A revolution in communication occurred with the development of the telegraph.
However, the early telegraph keys used to send messages caused severe strain
on the telegrapher's wrist - a condition now known as carpal tunnel syndrome.
In 1902, inventor Horace G. Martin patented the first in a line of devices
which solved the problem: the Martin Autoplex, an electro-mechanical sending
device which required batteries.
Two years later, Martin went into business with a group of entrepreneurs,
forming the United Electrical Manufacturing Company. It was also in 1904 that
Martin filed his second patent for a new sending device which used a weighted,
vibrating arm and did not require the use of a magnetic coil or batteries.
This device was the basis for the first Vibroplex.
In 1908, the association between Martin and U.E.M. ended when the latter went
out of business. However, J.E.Albright, who began a business catering to the
telephone industry in 1890, began marketing the Vibroplex for Martin. On March
12, 1915, Albright filed a certificate of incorporation in New York for the
Vibroplex Company, Inc. Within a few short years, Vibroplex came to represent
the best of the telegraphic, and later Amateur Radio, industry.

Vibroplex Company:

This CD link will take you to the
Complete Vibroplex Website as it appeared in 2006
and is reproduced on this CD.
It includes some history and a complete 2006
catalog of Vibroplex keys, parts, and services.
This CD also includes an
Illustrated List of Discontinued Vibroplex Keys.
and a great deal of additional material including some design drawings.
This CD also includes the
"Date your Vibroplex Keys" section of the Vibroplex
Website that presents the research of John Ellwood - WW7P that allows
you to learn the year in which your Vibroplex was made when you know its
serial number.
The following photographs show some of the day-to-day operations of the
company in 2006.
This is Felton "Mitch" Mitchell, W4OA, the President of the
Vibroplex Company.
Office Manager, Betsy Hopson, WB4ZYK, keeps up with all orders, email
communications, and customer service. "Vibroplex prides itself on our
customer service. Talking with the customers is my favorite part of the job.
You meet the nicest folks, many from overseas, and make friends for life. It
is especially nice to meet someone at a hamfest that you have been talking to
for years!"
Maura Durant's job is to keep up with all the inventory and keep
orders flowing to vendors and machinists. "This is a full time job, and it
surely does help me to understand what goes into the making of a key and you
can talk to customers better when you understand the parts."
Joan Turner is shown gathering parts for building keys.
Vibroplex has nearly 400 parts in stock. Many parts are still available for
obsolete keys. "Most parts are made by our machinist, Kevin Mills, while others
are subcontracted. We also subcontract plastic fabrication, chroming and
powder coating. Vibroplex is very fortunate to have Kevin Mills as our head
machinist. He is a brilliant problem solver and attends to details and
accuracy in all of his work."

Most of the components of the keys are assembled in advance to speed
the key making process. Liz Fearn puts together the mainframes for all
of the key models. The lever arms, contact posts, and damper assemblies
are all assembled in advance.
All Vibroplex keys are assembled by Joan and Liz. They may be put together
one at a time or in groups of five to 10 at a time. They make about
10 - 20 keys a day. Vibroplex offers customizing, left
handed keys and upgrades that include jeweled parts.
This is production manager Joan Turner in the Assembly Room.
Liz Fearn makes sure that each key is properly packed for shipment.
Vibroplex uses a special key insert and key box to secure the keys.
Then they are double-boxed for shipping. Liz says "We have found that
no matter how carefully an order is packed, the key may still be treated
like a bowling ball by the carrier. We stand by our customers to help
resolve any damage problems. That is why we strongly suggest that
customers keep the original key box in case they have to ship the
key in the future."
Maura checks keys in stock for shipping.
Maura says "We make every effort to keep a quantity of each model of key
in stock for shipping so that orders may be filled immediately. Sometimes,
however, back orders for parts delay our ability to ship a key despite our
best efforts."
This is Betsy Hopson, WB4ZYK, the office manager and refurbisher evaluating
keys that have been sent in for refurbishing. "Our philosophy is not to do
anything drastic to a key that would affect the age value and integrity of the
key. That is why we refurbish rather that restore old keys. The biggest
challenge to date has been several Hurricane Katrina keys that sat in salt
water for days. In that case the bases had to be replaced, but the top parts
were cleaned and allowed to show the corrosion spots as a reminder of what the
key and owner had experienced. I also have a great time with an old key like
the Model "X". Nothing is done to this key except for a good cleaning. Since
each part is cleaned individually, it is fun finding ways to keep track of the
parts and get them back together correctly!!" Betsy refurbishes about 40
keys a year.
This is the building that houses the Vibroplex Company in Mobile, Alabama in
2006.
