The most widely used source of electrical voltage for telegraph circuits was the 'Gravity' or 'Crow's Foot' battery and other similar 'wet' batteries.
0000t The first battery was demonstrated by Volta in
1799.(14KB)
He made his 'Voltaic Cell' by piling up alternating disks of copper
and zinc and separating them by salt-water moistened pads. This museum
quality handmade replica of the first voltaic cell was completed in 1999,
200 years after Volta made his first cell. Every detail has been
precisely recreated.

Pope:
After Volta demonstrated his battery, many versions were made. The most widely used of these was the "Crow's Foot" battery which was named after the unique foot-shaped zinc electrode.
Crow's Foot batteries typically were contained in a 6-inch diameter by 8-inch high glass jar. A copper star-shaped electrode rested on the bottom of the jar and an insulated wire led up and out of the jar carrying the positive voltage. A zinc "crow's foot" shaped electrode was suspended in the upper portion of the jar. The Jar was half filled with water and a considerable amount of copper sulfate or "blue vitriol" was added to the water. After a period of time, the battery would begin producing a voltage of about 1 volt.
The following description of how the battery works is from: "Electric Wiring" by Albert A. Schuhler. McGraw Hill, 1943. It is in the section entitled: "Telegraph Wiring, Job 208, Gravity Cell"
"The electrolyte is derived from a blue vitriol and water solu- tion. The blue vitriol must completely cover the copper element, and sufficient water must be added to cover the zinc element. A teaspoonful of sulphuric acid is added to this solution to give the best results. In order to prevent creep- ing of the electrolytic salts, the top of the jar is generally dipped into hot paraffine. Best results are obtained by pouring a layer of pure mineral oil over the top of the electrolyte, because it prevents evaporation as well as the creeping of salts. To put the battery into service after these steps have been taken, it is necessary only to place the cell an a short circuit for about 24 hours. This action produces a light liquid called sulphate of zinc, which forms around the zinc element and protects it. The copper sulphate solution, which remains at the lower end of the jar, is the heavier liquid. Very little care is required for the maintenance of gravity cells, because all they require is an abundant supply of blue vitriol and water. The best results are obtained when both liquids meet at a point midway between the zinc and copper elements. When the blue line falls too low, that is, on the level with or below the top of the copper element, blue vitriol and water should be added. When the copper sulphate begins to fade in color to a light blue, it indicates that blue vitriol should be added. Care must be taken that the blue vitriol crystals fall to the bottom and do not rest on the zinc crowfoot. The blue line should never be permitted to reach the zinc element. If the line rises anywhere near the zinc, the copper sulphate should be siphoned out by means of a hydrometer syringe, or the cell placed on a short circuit. As long as the cell continues in action, the quantity of sulphate of zinc increases. When this becomes too dense, or above 1.15 specific gravity, the top of the liquid should be siphoned out and water added to the remainder."
The following photographs show a typical crow's foot battery and its components: PLEASE NOTE: The battery shows the copper sulphate and water mixture BEFORE it separates into the two layers and no visible dividing line can be detected.

0005 WHITE CERAMIC WATERBURY BATTERY JAR COVER:(23KB)
This is a typical white ceramic battery jar cover. It was placed on top
of a glass battery jar and the electrical connections were made to screws
mounted in the holes on top of the cover. The battery manufacturer usually
cast their name into the cover and, in this case it is clearly visible and
reads: WATERBURY PRIMARY CELL, WATERBURY BATTERY CO. WATERBURY, CONN. USA.
It would be interesting to know the relationship between this company
and the GORDON Battery Company (See number 0001).
0006 WHITE CERAMIC EDISON BATTERY JAR COVER:(25KB)
This cover simply reads: EDISON, Made in USA. It has a special additional
hole (marked 'oil' through which ' battery oil ' could be added.
Edison battery oil covered the solution in the battery and reduced
evaporation.

10 * SINGLE-NEEDLE TELEGRAPH SET WITH GONG AND TELEGRAPH-LIKE KEY: (36KB)
This old wooden instrument measures 24" high by 9" wide by 6" deep. It
has a glass window through which the galvanometer needle can be viewed.
The three positions of the needle are labeled: TRAIN ON LINE/LINE
CLOSED/LINE CLEAR. The upper portion is supported by brass pedistals,
exposing a large electrically operated gong. A telegraph key knob juts
out forward from the right side of the instrument and doors open to
reveal that the key lever bends upwards 90 degrees to make and break
contacts. (Most needle telegraph sets use a right-to-left knob or 2
lever key to control the needle movement.) A hand written tag inside
reads:p 6 76. needle 160. bell 45. No 8 22. This unit was used to
control the movement of railroad trains on the British railroads.

19 * EARLY BRITISH RAILROAD TELEGRAPH SET:(15KB)
This early railroad telegraph set used a series of bell rings to
carry information about the trains which were operating. A wooden
cover which I was not able to obtain protected the coils and
contacts from dirt.
21 EARLY PORTABLE GALVANOMETER: * 2-1/4" diameter galvanometer in old
wooden box w/leather carry strap 70-0-70 scale. & room for dry battery.
24 TANGENT GALVANOMETER:(25KB)
A large 4" diameter horizontally oriented
compass indicator is located in the center of a 7" vertically oriented
coil of wire all mounted on a wooden stand with leveling screws. The coil
taps are marked 2,50,& 500. Made by Philip Harris Ltd,Birmingham,
England.
30 * THOMPSON MIRROR GALVANOMETER:(47KB)
Mirror galvanometers such as this were used to detect the weak signals
from early submarine telegraph cables, and by Thomas Edison during his
telegraph experiments. A kerosene light or candle was placed in front
of the unit and, when the mirror moved in response to weak electrical
signals, the reflected spot of light moved across a calibrated scale
mounted on the wall of a darkened room. Due to the laws of optics,
the spot of light moved over twice as large an angle as the mirror and
this served to amplify the sensitivity of the instrument. This is an
all brass mirror galvanometer standing on a brass tripod stand with
overhead Earth's Magnetic Field compensating magnets. It was made by
Elliot Brothers-London. Traded to Vince Thompson, K5VT.
31 ANOTHER STYLE OF MIRROR GALVANOMETER:(10KB)
This small mirror galvanometer has a white paper scale integrated
into its design. Light reflects from the moving mirror and onto
the white scale allowing measurements to be made.
32++ * Many MIRROR GALVANOMETERS:(45KB)
By several manufacturers, meter shunts, standard cells, standard
resistors, used to measure the tiny electrical currents on
telegraph lines and ground returns.
(For more details, See my
SCIENTIFIC INSTRUMENT MUSEUM in a different part of this website.)
33 ** ABRAHAM RHEOGRAPH PRISM SYNCHROSCOPE: (32KB)
The first dual-channel Prism Synchroscope. A horizontal rotating
prism provides a time-base for twin high sensitivity, low mass
mirror galvanometers. Projects dual-trace plus time-base information
on a screen. Used to display telegraph cable voltages as a function
of time. In original wooden box. Circa 1907.
35 * FARADAY PHILOSOPHICAL MOTOR: (35KB)
Same as permanent exhibit at Smithsonian. Twin circular mercury
pools with vertical rotating armiture. The first demonstration
of the rotational forces of electric current. Used as a philosophical
stimulus to early beard-scratching and thoughts about duplex telegraph
and polar relays. Circa 1830s.(Traded to John Williams).
40 UNUSUAL NEEDLE TELEGRAPH TRAINING SET: (50KB
This wooden set consists of a needle behind a glass window on one side.
There is a GPO stamp and a complete description of the code alongside
the meter as follows: A/\ B\/// C\/\/ D\// etc. Left deflections
of the needle signaled dashes and right deflections signaled dots.
Note that the code is NOT the morse code but the international code.
As one well-known British key collector told me: "We didn't have much
use for Sammy's code over here." Under this window there are two red
up-down key knobs. Pushing down the left knob moves the needle left
(dash). and the right knob moves it right (dot). The unusual aspect
of this set is that there is an identical window on the back of the
set so that an instructor can send on one side and a student seated
on the other side can practice receiving.
43 ** EARLY BENJAMIN PIKE DIAL TELEGRAPH SET:(15KB)
This is a very early dial telegraph sending and receiving set manufactured
by Benjamin Pike Jr. of 291 Boradway, New York. The transmitting unit
consists of a simple dial with the letters of the alphabet printed around
the edge. The dial of the transmitting unit is first set at the
top position marked Sign. Rotating this dial in a counterclockwise
direction causes a metal brush to make a series of electrical contacts
corresponding to how many letters have been passed. For instance,
turning it to the letter ''C'' would produce 3 electrical pulses.
43a A closer view of the dial:(19KB)
43b The BENJAMIN PIKE DIAL TELEGRAPH RECEIVING
UNIT:(15KB) consists of an identical dial to that on the
transmitter with a pointer that is moved clockwise by an extremely
early electrical coil-operated actuator. It steps clockwise exactly
one letter every time an electrical pulse is received. The pointer
is initially set at the center top of the dial and steps clockwise
until the last pulse is received and it is pointing at the desired letter.

45 MINIATURE FRENCH DIAL TELEGRAPH SET:(13KB)
This tiny sending and receiving set is patterned after the
British Wheatstone design. Rotating the sending dial to a letter causes an
interrupter to send a string of pulses which step the receiving
dial to the same letter. The lever on the side engages or
disengages the bell which rings for each pulse received.

46 UNUSUAL MINIATURE FRENCH DIAL TELEGRAPH SET:(13KB)
This is an unusual and tiny sending and receiving set that is
patterned after the British Wheatstone design. It is somewhat similar
to the set described above however, a tiny telegraph key with an
ivory knob is used to generate the pulses which rotate the dial
of the receiving set to the appropriate letter. The unit is
incomplete. It is missing the solenoid coils and other
parts of its mechanism.

48 * VERY UNUSUAL PORTABLE FRENCH DIAL TELEGRAPH TEST
SET: This lovely set was sold at the 2005 Antique Wireless Association
conference. The set allowed the telegraph lines to be tested at any
location by simply throwing a wire over the telegraph line and inserting
another wire into the ground. The set could be closed to protect the internal
apparatus while transporting it.

50 THE ORIGINAL MORSE TELEGRAPH KEY was actually a notched piece of metal
called a Portrule. It was pulled along and the parts of the metal that were
not notched made contact with another piece of metal, completed the electrical
circuit, and produced the dots and dashes of the Morse Code.
50a THE VAIL 'CORRESPONDENT':(41KB) This simple so-
called 'strap key' was used in early tests by Morse and Vail that led up to
the 1844 demonstration. It was given the name 'strap key' because it
consisted of just a simple strap of spring brass.
50b THE ORIGINAL MORSE TELEGRAPH KEY CALLED THE 'LEVER
CORRESPONDENT' THAT WAS USED IN THE 1844 BALTIMORE-WASHINGTON
DEMONSTRATION:(36KB) This key is on display in the Smithsonian Institution
in Washington, DC and it is on loan from the Vail Museum in Morristown,
NJ.
50x A REPRODUCTION OF THE VAIL LEVER CORRESPONDENT MADE BY

51 ** EXTREMELY EARLY PALMER AND HALL BOXED COMBINATION
TELEGRAPH KEY AND RELAY SET:
This extremley rare Palmer and Hall telegraph set is contained in a wooden box
that protects the early camelback key and relay from damage. One end of the
box folds down to allow operation of the set while still in the box. The
relay and the box are labeled: Palmer and Hall and the box label reads: PALMER
& HALL electricians, 158 Washington St. Boston, Mass. The box measures: 8.5 x
6 inches. The owner was kind enough to allow me to include these photographs
in my museum prior to selling it on ebay.

52 ** EXTREMELY EARLY TELEGRAPH AND MINSTREL AMBROTYPE:
(57KB)This extremely early ambrotype is from the Jim Bollman (email:
jim@themusicemporium.com ) collection of very early banjos. It is copyright
(c) Jim Bollman and it is provided courtesy of The Music Emporium
( http://www.themusicemporium.com ).
Ambrotypes were introduced after dagerreotypes and around the middle of the
19th century. They consist of a transparency which is mounted on a black
background. This one shows a grouping of 8 young boys with a banjo and two
telegraph instruments. The grouping and banjo indicate that these boys are
members of one of the popular minstrel groups of the mid 19th century. Three
of the boys are wearing hats and at least two are wearing uniforms which
suggest that they work in a telegraph office. They are holding two extremely
early telegraph instruments and I believe that this is the earliest photograph
of these instruments that has been found.
The left instrument appears to be a Thomas Hall relay similar to the
number 68 ** Palmer & Hall relay shown in my
museum:(16KB)
The right instrument appears to be a similar Hall relay mounted on the same
board with a very curved telegraph key which may be an Hall or some other key.
If it is an Hall key, it is much earlier and more elaborate than the number 67 Hall telegraph key in my museum:(15KB)
Click here to see an enlarged (but very slow loading)
view of this entire picture:(191KB)
I have selected the right instrument and enlarged it to allow much
closer inspection. This is an enlarged view
with no sharpening:(17KB) It reveals that the key has a light-colored
probably ivory knob.
Adding a very high degree of sharpening allows a few more
details to be seen:(26KB)
Still more enlargement:(8KB) starts to show more
additional details of the key's design. However, you will probably have
to step quite far back away from your computer screen to view it.
CONCLUSION: I believe that the key is a Palmer and Hall camelback as
shown in This picture from the Hall Catalog:(12KB).
Although it is difficult to see all of the details in the ambrotype
because the head of a minstrel gets in the way, most details seem to match
the catalog illustration.

53 VERY EARLY PALMER AND HALL OR HALL BOXED PORTABLE
COMBINATION TELEGRAPH KEY AND RELAY SET:
This extremely rare portable telegraph set is enclosed in a strong wooden box
that protects the tiny miniature straight lever key and miniature relay
from damage. The overall design and the spring adjusting mechanism for the
relay is quite unusual. Although there are no obvious markings on the set,
the knurling on the hardware, the shape of the parts, and the design strongly
suggest that it was made by Palmer and Hall or Hall in Boston, Mass.

55 EXTREMELY EARLY CATON 'MORSE'
WEIGHT-DRIVEN REGISTER:(54KB)
This extremely early Morse Register is a fine example of the first
style of paper-tape recorder to be used on the telegraph lines. It
is powered by a weight and pulls a paper tape past a stylus that
makes indentations in the tape for dots and dashes. It was used
in a railroad depot in Stockton Springs, Maine. It was acquired by
James Coose (W1CBU) of Stockton Springs when the station closed and
given to his son-in-law Robert Littlefield (W1MFU) and transferred
to this museum by Diane Coose Littlefield in 1996. It was made by the
Caton Instrument Co. in the 1850's.
The base is stamped: OTTAWA - ILL 433.

This early straight lever key was made by the Caton Instrument Co.,
Ottawa, Ill. The long legs pass through holes in the operating table
and wires are attached to binding posts at the end of each leg.
The lever is stamped CATON, OTTAWA, ILL 7?? (illegible),
and the base is stamped with the number 494. Circa 1860's.
57 ** EARLY CATON 'LINEMAN'S TEST SET OR POCKET
RELAY:(18KB)This magnificent pocket relay or 'lineman's test set'
consists of a sensitive sounder and a very early and tiny strap key.
There is a tiny ivory knob on both the key and the shorting lever.
These sets allowed linemen to tap into telegraph lines with a pocket-sized
instrument and they were also used by the military for intercepting and
sending false messages to the enemy. The set is enclosed in an
oval hard rubber case and in a thick leather protective case.
These pocket sets are very hard to find and this one is owned
by collector Bill Carpenter, AA8EY.

60 VERY EARLY ELABORATE CAMELBACK KEY & SOUNDER:(63KB)
This all brass key with leaf spring has a massive elaborately curved
lever of the earliest "camelback" or "humpbacked" shape which was
adopted soon after Morse's demonstration. These keys were only made
for a short time because the steel shaft, press fit into the lever,
tended to work loose with use. The sounder is also heavy brass but,
although it was mounted on a board along with this key, I believe that
the sounder may be from a later period. The original wooden base is
missing. The two instruments came from a burned railroad
station in Canada. Circa 1848. The lever shape and large dished
adjusting screw heads are very similar to the two keys shown below.
It has been suggested that these keys were all made by the Dominion
Telegraph Company in Canada but unfortunately, we have very little
information about Canadian Telegraph Companies.
62 VERY EARLY ELABORATE CAMELBACK KEY:(32KB)
This all brass key with early hairpin spring has the same massive
elaborately curved lever as number 210. The hairpin spring suggests
that it is of a slightly later design. It is stamped NWT, the
initials of the early Northwest Telegraph Company of Western Canada.
All underside parts are stamped "2" and it is also stamped 1880., an
inventory date? It came from Canada. Circa 1850.
63 VERY EARLY ELABORATE STRAIGHT LEVER KEY:(32KB)
This extremely early all brass straight lever key is very similar to
the two extremely early camelback keys above. Note that the shorting
lever and adjusting screws are virtually identical to those above.
Like the two camelbacks, it was also located in Canada and it may have
been made by the Dominion Telegraph Company. Circa 1850's. Collector
Pete Malvasi, W2PM owns a sounder which appears to match this key and which is
labeled Dominion Tel Co. and this lends credence to the suggestion that
Dominion made this key although the key below is very similar to this key and
carries the label: FOSTER, Toronto suggesting that this key might have been
made by Foster.

STRAIGHT LEVER KEY {One Mystery Solved!}:(32KB)
This extremely early all brass straight lever key is very similar to the key
above (Number 0063). Note that the shorting lever and adjusting screws are
virtually identical to those above. This key is labeled: FOSTER, TORONTO and
it appears to be a very early key made in the 1850s. Several keys have
turned up in the last 10 years that are similar to this key but none of them
has carried a maker's name. It is apparent that this key solves the mystery
of who made these other keys by showing that it was "FOSTER" of Canada who
made them.

70 VERY EARLY CHARLES CHESTER WEIGHT-DRIVEN MORSE REGISTER:(18KB)
This very early register was made by Charles T. Chester of New York in
the 1850's. It is an embossing register which means that it marked
dots and dashes by making impressions in the paper tape rather than
by depositing ink on the tape.
A pair of them was originally purchased and one was traded.

80 CIVIL WAR ERA PHELPS CAMELBACK KOB,
Marked G.M.PHELPS-MAKER.:(27KB)
These Phelps Camelback keys were the most widely used of the Civil War keys.
Camelback keys have an upward lump like a camel's hump on the lever
between the knob and the pivot. They were only made for about 12 years
from 1853-1865 because the steel trunnion shaft which was press-fit
into the lever would gradually work loose with prolonged use.
The brass lever would then slide left and right making the key unusable.
This key is all brass except for the steel trunion shaft. The key has a
shorting switch and the revolutionary Phelps-invented spring adjusting
screw which was copied and used on just about every key manufactured
after his invention. This particular Phelps key is mounted on
wooden base with its legs shortened to fit into the base. (a common
but unfortunate modification.) A very early
and primitive Tillotson sounder is also mounted on the base making
it into a portable Key (and sounder) On Base, commonly called a
KOB.(1860's)

I have often been asked for drawings of the historic Phelps
Camelback Keys by Civil War Reenactors and others who are
interested in making replicas. I have traced a Phelps key
onto 1/4-inch squares graph paper and added the dimensions as best
my shaky hands would allow and I hope that there is enough information
to allow people to build a key from these plans. I offer these plans
in low, medium, and high levels of resolution. They are
copyrighted but single copies may be made and printed for individual
use by any interested person. I would really appreciate seeing
pictures of your completed or in-progress keys!!

90 ** CIVIL WAR TELEGRAPH OPERATOR'S TOMBSTONE WITH
KEY AND TELEGRAPH POLE:(27KB)
This tombstone was erected in honor of James Francis Leonard of
Frankfort, KY. He was a telegraph operator during the Civil
War and is credited with having discovered that the sounds made by
a register as it impressed dot and dash marks on paper tape could
be copied by ear. This led to the widespread use of sounders
for copying the Morse code although many people still insisted
on a permanent paper tape record of the messages because they
did not trust copy-by-ear. In 2004, I was sent a photo of the base of
the tombstone showing the name 'Taylor'. I do not know the significance
of this name.

Edmund Prandstatter of Munich, Germany. It is interesting to note
that registers were still being produced and sold at this late date
in Germany while Americans had abandonned registers in favor of
copying code by ear from sounders around the 1860's. It is also
interesting to note that there are NO sounders offered for sale
anywhere in the catalog !!

(KROB) SET:(21KB)
This set is a typical example of the early European land-line telegraph
systems which consisted of a straight-lever German-design key,
an ink writing register, and a galvanometer for measuring the
condition of the line. It is called a ''KROB'' set which stands for:
Key and Register on Base. A roll of paper tape on which the dots and
dashes were written (in ink) is stored in the drawer under the register.
This set is stamped with the French manufacturer's name but the
design of the key and register are clearly Siemens.
The name stamped on the set reads: Societe Industrielle des Telephones,
25 Rue du 4 Septembre, Paris. I believe that the set was probably
originally manufactured or certaily licensed by Siemens.
NOTE the interesting telegraph key which has the characteristic
German Siemens spring-mounted lower contacts AND surprisingly, it has
two tension springs. One spring is mounted in front of the trunnion
and one spring is mounted in back of the trunnion. It is unclear
why the spring in back of the trunnion was needed.
The only other two-spring key that I have been able to find is
listed in the Spark and Radio keys' and the 'German Military keys'
sections of this museum.

190 LARGE WESTERN UNION TRANSATLANTIC CABLE KEY:(51KB)
Two large old brass levers mounted on a 4-1/2x6" black rubber base.
The left lever was used to send dots. Pressing it drove the cable
voltage positive. The right lever was used to send dashes and drove
the cable negative. Since the cable was thousands of miles long,
it acted as a huge capacitor and the full plus-to-minus voltage was
necessary to help it discharge. The messages were recorded on a
moving paper strip and it took skill to visually tell the difference
between dots & dashes.

192 LARGE ELLIOTT BROTHERS TRANSATLANTIC CABLE
KEY:(51KB)This is a very fine example of an early submarine cable key. It
has survived in very good condition and shows a plethora of adjustments that
allow it to be set to the exact tension and spacing desired by an operator.
The left lever was used to send dots. Pressing it drove the cable voltage
positive. The right lever was used to send dashes and drove the cable
negative. Since the cable was thousands of miles long, it acted as a huge
capacitor and the full plus-to-minus voltage was necessary to help it
discharge. The cable messages were usually recorded on a moving paper strip
and it took skill to visually tell the difference between dots & dashes.
This key, however, was used with the super-sensitive relay shown below
instead of the typical paper tape recorder.

193 SUPER-SENSITIVE POLAR RELAY USED IN SUBMARINE
TELEGRAPH CABLE LINES:(70KB)The electrical signals on a submarine
telegraph cable were usually recorded on a moving paper tape and then
translated into letters by eye. This relay has the extremely high resistance
of 506 Ohms, making it sensitive enough to detect the very small voltage
changes in a submarine cable. In addition, it has numerous very fine
adjustments that allow it to be set to react to very weak signals such as
thouse received over very long cables. There is some engraved writing on the
top of the relay but I have been unable to read it because it is not engraved
deeply enough into the metal. This relay was located along with the
Elliott Brothers Submarine Telegraph Cable Key shown above and was probably
also made by Elliott Brothers.

212 COMPLETE PORTABLE WESTERN UNION TELEGRAPH
OFFICE:(17KB) This is a complete portable 1870's Telegraph office.
It is contained in a special box which serves as a desk and which can
be attached to a telegraph pole.
It was carried in a railroad car and used for emergency communications
along the railroad line. This is a very interesting set so I have included
many different views of it and it's components. Several views are
very similar to each other but have slightly different color balance.
As you can see, the set can be attached to any convenient telegraph
pole using a chain attached to the back of the cabinet.
It can be electrically hooked into any telegraph line using the
special connector called a 'Wrecking Clamp'. A blueprint shows the
wiring of many of the telegraph poles along the railroad line so the
telegraph operator can know which line to tap into.

232 EXTREMELY UNUSUAL STRAIGHT LEVER FLAT TERMINAL LEWIS
KEY:(16KB) This is the strangest Lewis Key that I have ever seen.
The lever is nearly straight which is unusual for Lewis keys but
the most unusual aspect of the key is the three flat-topped terminals
which, as you can see from the underside view connect to the
normally open, normally closed, and frame of the key.
There is no way to connect wires to these terminals directly so
I can only assume that the key was slid into some sort of spring
loaded contact assembly. I have included several different views
of the key.

because they made a permanent record. This is a very early brass
register with an unusual armiture which presses the paper tape up
against the (missing) pen to mark dots or dashes on the tape in
ink. It has a key wound mechanism (with key) which runs
constantly.

patent reads "Patent July 1874. No address on base. >Traded out.
693 * UNUSUAL TRANSITIONAL SOUNDER WITH VERTICAL
AND HORIZONTAL SPRINGS:(17KB) This is an interesting sounder
which has parts for both horizontal and vertical springs. Although
the Anvil is broken off, you can see where the horizontal spring
adjusting screw was mounted. You can also see how the vertical spring
was mounted. The transition from horizontal springs to vertical
springs is generally believed to signal a major shift in
sounder design strategy and this sounder appears to incorporate
both designs.

694 * VERY EARLY GREELEY SOUNDER: All plated. E. S.GREELEY & CO.
5 & 7 Dey St. New York.
740 VERY UNUSUAL SOUNDER-ACTUATOR?:(8KB)
This extremely unusual sounder/Actuator was found at an abandonned
railroad station in the far west. It is of cast iron
construction and looks very early. The sounder mechanism has
an added long lever which allows it to act as an actuator to
perhaps activate another mechanical mechanism.
800 * EXTREMELY EARLY TILLOTSON RELAY:(33KB)
This extremely early L.C. Tillotson relay exhibits the early
spring-through-the-post design along with the post-mounted contacts.
These features were abandonned early in the design of relays. It
is stamped L.C.T. & CO. 6 DEY ST. NY. 60 ohms. Circa 1850's. (Traded
to John Casale - W2NI.)

1005 THOMAS A. EDISON DUPLEX TELEGRAPH MODEL:(30KB)
This model, manufactured in Edison's laboratory consists of a
1 X 2 Ft. board (28KB) with a
set of wires on the bottom (34KB).
On this board, 3 wind-up clockwork mechanisms labeled "Terry Clock Co.
Waterbury, CT, Pat'd Dec 1, 1868 are mounted.
Each clockwork mechanism has had its escapement
removed and replaced with an air-propellor to govern its speed (47KB).
Each clockwork mechanism turns a rotating disk that
makes contact with an adjustable wiper contact (46KB).
The disk has an insulated spot that breaks
the contact at an adjustable point in its rotation (54KB).
The device was an early experimental model of a form of mechanical
time-division multiplex designed to allow 3 telegraph messages to be
sent on the same line.

1012 SIEMENS BROTHERS CABLE KEY:(29KB)
This massive cable key has its entire mechanism mounted on high
columns above the base because of the high voltages which
were often necessary in order to transmit messages through
the very long cables. It measures 6-1/4"long by 4-1/2"wide
by 5" high. The base is stamped Siemens Brothers & Co. The
unusual triangular levers are used to hold the contacts in
the closed position.

Large and massive cable key similar to 1012 with the high
voltage columns but labelled Elliott
Brothers and with brass handled shorting cams.>K5VT
1015 UNUSUAL ROCKER-TYPE BRITISH CABLE KEY:
This is a very unusual cable key that uses a rocker-type mechanism.
Pressing the left knob puts a positive voltage on the cable and pushing the
right knob puts a negative voltage on the cable. There is no maker's name on
the key but the hardware strongly suggests that it is British.
1016 * Ted Huston's CABLE DISCHARGE KEY:(14KB)
This large key was used to discharge the capacitances on
the long submarine cables in order to permit measurements.
The high columns isolate the high voltages on the mechanism from
the base. It is in the Ted Huston collection.

stamped WESTERN ELECTRIC CO.
1025 * VERY EARLY STRAIGHT KEY: Old all-brass key has a straight 1/4X1/4
inch brass lever bent down for an early-style knob. Wooden base with
cotton-covered wires embedded in channels on the underside. The spring
has a long gentle taper like Clapp-Eastham "Boston" key which it slightly
resembles.
1026 * VERY EARLY STRAIGHT KEY & SOUNDER:(32KB)
Key like #1025 with matching sounder.
1050 BEARINGLESS ''STEINER'' KEY: (20KB)
The Steiner key is a very small key which is characterized by
having no trunnion or bearings. The lever is supported only by a spring
and knife edge. This one has a brass base which is stamped
W.E.Co. New York. Pat'd Dec.21,1880. Mounted on newer wooden base.
1054 ''RESTORED'' STEINER KEY: (17KB)
This is a small Steiner Key which has had its long legs cut off
so it could be mounted on a metal base. The key has been
chrome plated and the insulators have been replaced with white
plastic material. The shorting lever knob has been replaced with
a machined knob. I personally prefer to leave these keys in the
as-found condition with perhaps a light cleaning to remove dirt.

Pat'd Dec.21,1880. This one has been mounted on a newer marble base.
1057 * STEINER KEY WITH UNUSUAL WESTERN ELECTRIC
SOUNDER:(15KB)
This Steiner Key was used with this very unusual Western Electric
Sounder. The key has a brass base stamped W.E.Co. New York.
Pat'd Dec.21,1880. The sounder has an unusual round anvil. I believe that
this is a transitional design between the Western Electric
rectangular frame sounders and the Western Electric all round
frame sounders.

1062 * PRIVATE-LINE CAST-BASE KOB WITH STEINER
KEY:(35KB) This KOB has a Steiner Key and sounder cast into
it's base. Private-Line KOB's were designed to be used on
''private telegraph lines'' in homes and businesses. They were
made on cast iron bases which were often decorated with flowers
and designs to better integrate into a home or business environment.
1067 EXCEPTIONALLY UNUSUAL STEINER KEY AND STRANGE AND
COMPLEX RELAY ON WOODEN BASE, KOB:(40KB)
This instrument was probably made and used by Western Electric since they
were the most frequent users of Steiner keys. Its base was covered with mud
indicating that it was immersed in a flood at some time. Removal of some mud
revealed that the base and key were painted black while the relay was nickel
plated brass.
The Steiner key is the only one if its kind that I have ever seen. It has a
rectangular frame over the lever. This rectangular frame converts the
normally-open contacts of the Steiner key into normally-closed contacts. All
of the Steiner keys that I have seen are configured like the one on the
Private-Line KOB and other Steiner keys shown above and have normally open
contacts and no rectangular frame. I believe that the closed-circuit feature
of this Steiner key was probably found to be necessary to work with the
complex relay system to produce some sort of duplex operation.
The most unusual feature of this instrument is the extremely complex relay
mounted on its wooden base. It was probably used in some kind of duplex
circuit. Duplex circuits often employed complex relays in an attempt to send
two signals on the same line and this is certainly a very complex relay. It
has a set of single-pole double-throw contacts on top that move back and forth
when BOTH of the coils are energized simultaneously. It has another set of
single-pole double-throw contacts located toward the key that move from side
to side when one OR the other coil is activated or when there is an imbalance
in the pull exerted by the two coils. This is generally called a polar relay
configuration in that the contact remains in its last position untill pulled
over by the other coil. It is also clear that a box, probably made of wood,
was mounted on the four pins that stick up around the relay. The exposed
coils that could be easily damaged also suggest that the box was used to
protect them and perhaps to keep people from trying to adjust the
very delicate mechanism. Close views of the underside of the base show that
the wiring was changed probably several times in what must have been an
attempt to explore different circuit configurations.

A modern version of the lovely Ericsson keys shown below. (This key
is the same as number 5050.)
1200 LARGE EARLY SWEDISH ERICSSON-STYLE KEY:(15KB)
This is the classic early Swedish land-line key made from the 1870s well
into the 20th Century. The key has a very long lever and a crisp 'feel'.
Operators were trained to sit in front of the operating table with their
upper arm straight down and their lower arm pointing straight ahead. Their
seat height was adjusted so their arms made a right angle with each other.
Their lower arm was thus parallel with the operating table. They were
taught to grasp the key knob firmly with thumb and forefingers and to
use ONLY up and down whole-arm movements to operate the key. You can see
the cuts in the wooden base which were used to allow the wires to come
up to the key connectors from the operating table. This is my
all-time favorite key to own and to operate on the air.
1215 SWEDISH ERICSSON-STYLE KEY: (49KB)
Very large old all-brass key on a wooden base with very long lever and
beautiful brass hardware and switch block. Made in 1880's by ERICSSON

EARLY DANISH - GREAT NORTHERN TELEGRAPH WORKS KEY:
This Danish key carries a label that reads: Great Northern Telegraph Works,
Copenhagen, Denmark. No. 77773. It is not likely that 77773 of these keys
were made since they do not show up very often. I think it is more likely
that the manufacturer started with a high serial number. The picture was sent
to me by another collector.
{1223} 5070 * {Duplicated from Wireless Keys section.}
LATER DANISH - GREAT NORTHERN TELEGRAPH WORKS KEY:
This appears to be a later version of the Danish key above. This Danish key
carries a label that reads: Great Northern Telegraph Works, Copenhagen,
Denmark. No. 13779. Since it is not likely that 13779 of these keys were made
it is more likely that the manufacturer started with a high serial number.
Circa 1960s. The picture was sent to me by another collector.
