Patent Number Date Title Name City Description
817,587 Apr. 10, 1906 Machine for drilling nuts and the like Martin Nelson ON, Canada This multiple-spindle drilling machine was sold by Nelson-Blanck Manufacturing Co. as a drilling head accessory. Ads from 1914-1917 feature their two-spindle version; from 1919 to 1921 they also offered versions with 3, 4, 6, 8, 10, or 12, and available in both in-line and circular configurations. The distance between spindles was adjustable. They also offered custom designs. In 1925 it appears that Nelson-Blanck was acquired by Buhr Machine Tool Co. and we assume that firm also manufactured these patent drill heads.
121,993 Nov. 16, 1909 Machine for making blank nuts Martin Nelson Detroit, MI 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 Manufacturing 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.
