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
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.
