Another of Bangerter’s machines would take small, smooth, round steel rods and automatically make perfectly finished pinions with pivots, shoulders and smallest holes. An automatic trumpet of his invention would play a complete tune and was so simple in operation that a one-year-old child, by simply blowing in it, could play it. United States Patent 543668 for a Hair Clipper, issued to F. Bangerter, San Francisco, is specified as follows:-- 543668. Hair Clipper. Fred Bangerter, San Francisco, Cal., assignor, by mesne assignments, to Charles H. Greene, same place. Filed July 21, 1894. Renewed July 2, 1895. Serial No. 554,715. (No model.) Claim 1. In a Hair Clipper, the combination of the stationary and movable plates, a pair of pivoted handles, one of said handles being hinged or connected with one of said plates so that the device may be turned to different angles, an opposing plate having its rear portion recessed and provided with rearwardly and upwardly extending curved arms, and the other handle having arms adapted to enter the recess of said plate and engage the curved arms thereof in whatever position the device is turned. In 1892 he exhibited an automatic figure in a big department store in San Francisco which drew a complete portrait of Christopher Columbus. United States Patent 512089 was issued to Mr. Bangerter for an “Automatic Delineating Machine,” a toy doll which would correctly write the complete alphabet. Later he so improved this figure that it could spell and talk while writing. At the Paris Exposition in 1900 he exhibited a most remarkable machine which made collar buttons. Three rods of metal were used at the same time--one to make the head of the button, one the bottom or base, and the other the stud. The three parts of the collar button were perfectly made and finished. The head was drilled and tapped, the stud was threaded and screwed into the head while spun into the base or bottom. The manufactured collar buttons fell into a box at the rate of 300 an hour--thus effecting a great economy of metal. In 1905, at the Belgium Exposition, he displayed an intensely interesting novelty--an “Automatic Jeweler"--which, with arm and hand, operated an ordinary machine which turned out perfectly made collar buttons of which thousands were sold within the Exposition Grounds. A most marvelous contrivance was his four-spindle [Illustration: BANGERTER’S AUTOMATIC FOUR SPINDLE WATCH CHAIN MACHINE, Composed of Over Three Thousand Parts.] automatic watch chain machine composed of over three thousand parts. This machine made from wire of four different metals, namely, gold, silver, nickel and German silver, being fed into the machine at the same time would automatically make four watch chains of four different patterns completely and properly finished. The chain itself, an invention of Mr. Bangerter, was called the Bangerter Chain. Patent sold in France. BANGERTER’S POWDERLESS GUN.
