Abstract

581,875. Drilling. POBJOY AIRMOTORS & AIRCRAFT, Ltd., and STENHOUSE, J. July 10, 1944, No. 13149. [Class 83 (iii)] The depth of feed in a drilling &c. machine, particularly a portable machine, is limited by a stop attached to the casing or other fixed part and contacting with the work. A sleeve 10, attached to the casing 11, carries a stop 14 surrounding the drill. A screw 141 engages a helical slot to adjust the amount of feed, or in a modification the parts 10, 14 have a screwed connection. A scale and vernier may be provided to indicate the setting and apertures 143 provide for the escape of cuttings.
