Democratic Sentinel, Volume 16, Number 25, Rensselaer, Jasper County, 8 July 1892 — Screw Machine. [ARTICLE]

Screw Machine.

C. M. Spencer, of Windsor, Conn., the Inventor of the original screw machine and the Spencer repeating shotgun, has been at It again. This time he has made a device that turns out eight screws a minute, with slots and threads cut all ready for packing. One peculiarity of the machine is that It requires little or no attention. After the apparatus Is started it will go on making screws until the material gives out. Sometimes Mr. Spencer starts it up and goes to Hartford. He stays all day, and upon his return at night the machine Is still grinding out screws.
