Machine for drilling nuts and the like
|
Martin Nelson |
ON, Canada |
This multiple-spindle drilling machine was sold by Nelson-Blanck Mfg. 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. |

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 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. |
