Gil Schlehman searched the patent office for telegraph-related patents and
compiled the following list. It specifies the patent number, the person to
whom the patent is assigned, the location, the date, and any useful
information about the patented item.
The first three pages show a listing of all of the telegraph-related patent
numbers. These patent numbers were extracted by searching all of the patents
using a set of guidelines. The specific guidelines that were used for the
search are shown below the three pages of listings. These three pages and
the last page may be searched by using the Edit/Find(on this page)
feature of your browser.
The fourth page is a copy of the guidelines for locating the appropriate
indexing codes used to identify specific telegraph related instruments. This listing was
used to locate the telegraph items listed in the three preceding pages.
Clicking on this picture will either enlarge it for easier reading or bring up
an 'enlarge' button depending on how your computer is set up.
The fifth page shows the actual telegraph patent numbers that were extracted
by the preceding guidelines. This page may also be enlarged by clicking on
it.
The sixth page is a simple but VERY useful list of patent numbers and
their associated patent dates. This list should be helpful in dating
antiques for which the patent number is known.
