This particular key was made in , and is known as the “original” model. Production of keys of this type began in , and are they still being made today. Originally, they were used strictly by landline telegraphers, but once radio came into use, they became favorites of radio operators as well. Today, their use is largely restricted to the amateur radio community. With such a long production history, these keys are not especially rare, but this example is in exceptionally nice condition, and still has the original nickel plating on the operating parts, and the decorative pinstriping on the black finished cast iron base is also largely intact. A key of this type allowed a skilled operator to send code at a faster speed, with less fatigue, than was possible with a standard key. The secret of its operation is weighted rod center left in the pictures that is joined to the operating lever with the black knob and paddle at the right by a piece of spring steel. As the lever is moved to one side, the rod vibrates and produces a series of dots using the contact just above the nameplate. Dashes are produced by moving the lever to the opposite side, once per dash, using the contacts at the far right.

December 22, Levey goes to Federal District Court for infringing on the patents of Mecograph / Martin / Vibroplex telegraph keys. At the time Max Levey was operator of the AtoZ Electric Novelty Company, which was producing clone versions of the Vibroplex Original semi-automatic telegraph key.

Martin, a New York inventor filed a patent on May 7, for a completely mechanical semi-automatic morse code transmitting key, which he named the “Vibroplex. Pushing a paddle mounted on one end of the lever to the right caused a spring-mounted contact further along the lever to vibrate against a stationary contact, making strings of dots. Dashes were made manually by pushing the lever to the left.

The speed of the dots could be altered by sliding a weight along the lever. Virtual Bug Project v. A Vibroplex No 4. Later named the Blue Racer bug key. A super example of this model with a black japanned base with the lovely gold detailed pinstriping, plus a U shaped damper mechanism. The main arm has been replaced at some time and is longer than normal, but this anables an extra weight to be added to slow the dots down.

John Elwood, WW7P, did a heroic job of determing the age of Vibroplex keys by serial number. One place to find his document is on the Vibroplex site here. Using WW7P’s data, I built a spreadsheet and calculated how many serial numbers were used in each year from to and then I graphed it.

This usually involved wrapping the cable with brass bands to keep it from unraveling and stripping it so that the individual layers could be seen.

This cable was laid from France to England in the ‘s and is an interesting example of early telegraph cable design. Several pieces of this cable were generally saved and made into museum and display pieces to commemorate the laying of the cable. This process usually involved applying a metal band to one end of the cable, peeling back the other end to display the internal layers and construction, and signing the metal band with the maker’s name.

This is a commemorative piece of a submarine telegraph cable which was laid over years ago to connect France and England. It was manufactured by Siemens and Halske whose name appears on the metal band.

The action is quite complex and operates on the ‘release of tension on the lever’ principle to circumvent the Martin-Vibroplex patent.

The Vibroplex exhibit booth was constantly busy and sold a lot of keys and parts. This is the only known example of this incredibly small and exceptionally strange bug.

It carries the stamped wording: The threading on the screws does not appear to be American standard so the bug may have been made in Britain or some other country. I would tentatively date the bug in the time period based on the hardware and appearance of the parts. This is not a one-of-a-kind bug because it carries serial number 7 stamped into the end of the base and its major internal metal parts are internally labeled with Three letter “G”s stamped into the metal.

Note that “G” is the 7th letter in the alphabet. The bug was first received in disassembled condition. Although the main upright that supports the upper pivot of the dot lever is missing it has been possible to reassemble the bug so that its design and operation can be studied.
