Abstract

208,210. Chopping, F. Sept. 11, 1922. Drilling-machines.-In hand and power driven drilling or like machines in which the feed mechanism is allowed to slip when the tool meets excessive resistance, the spindle b engages a screwed sleeve c rotatably mounted thereon by means of a spring pawl h. The pawl is pivoted directly to the spindle at h<1> and its pressure on a notched disc c<1> integral with the sleeve is adjusted by a spring j<2>. The machine frame consists of a bracket a adjustably mounted on a pillar or angle bracket e which may be secured to a bench &c.
