Description:

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.
