Description:

The available information on this patent only give the inventor's location as "United States". We guess his location to be Detroit given the then-recent establishment of the Nelson-Blanck Mfg. Co. in that city to make the inventor's patent multi-spindle drilling head.

This patent shows a machine that cuts nut blanks from bar stock of appropriate cross-section, in contrast to the usual method, at the time, of punching the blanks out of sheet steel. This machine's method was claimed to make a stronger nut.
