Vibro-shave
The Vibro-Shave electric razor was manufactured by the Electric (Safety) Razor Corp., which was located in Long Island City (NY, USA), and (initially) sold by the Electric Razor Sales Company of America, with offices at Chicago, New York City and Montreal. The Vibro-Shave was a double edge safety razor with a small AC-only machine in the handle, which made the apparatus vibrate. In 1925 a patent for this "vibratory razor" was granted to Saul Shaler of New York, and assigned to the Electric Safety Razor Corp. The patent describes a solenoid magnet and a spring return to provide the vibratory movement. Usually the razor took alternating current, in the early days from a light bulb socket. For direct current an interrupter device could be used. The Vibro-Shave razors have been sold in the second half of the 1920's and later. Unlike the Lek-tro-shav and the Collins, there are still many Vibro-Shaves on the second-hand market, which means that this must have been one of the first successful electric safety razors. Several versions of this shaver have been produced. There was a Model A (chromium plated, without on/off-switch, $5.-) and a Model B (gold plated, with on/off-switch, $7.50). Vibro-Shave also marketed a beauty-set.
I just saw two of these for sale at a local to me antique store! I had no idea what it could possibly be! That handle is huge! It was exactly like the red one above....
