Apparatus for Effecting Electrical Signaling
In earlier blogs in this series, we have discussed a number of patents related to electrical signaling that involved George Owen Squier. Squier, an Army General, was also the Chief Signals Officer during World War I.
Patent number 1608252, Apparatus for Effecting Electrical Signaling, was like some of the other Squier patents, a collaborative effort. This patent was granted to Squier, and Joseph O. Mauborgne and Louis Cohen. It was granted in November 1926. Like other patents related to electric signaling (e.g., 1641608, 389451, and 566442) this patent offered refinements to telegraphy.
The patent states that it offered a device to increase the speed at which signals could be transmitted and received. The apparatus could, the patent says, be applied to cable, wire, and radio telegraphy. The patent also states, however, that the inventors do not claim the method or apparatus generating the signals at the transmitting end, but only that “the respective dots and dashes which constitute the signal shall vary in amplitude but not in time.” The machine consisted of the receiving circuits for dots and dashes, circuitry, vacuum tube amplifiers, detectors, and relays.
The device offered the capability to receive “telegraphic signals where the dots are distinguished from the dashes by variations in amplitude” by employing a means to amplify the signal. The purpose of the invention was to enhance the strength of the dot and dash currents. This would enhance the quality of the message received.
