Abstract

613,769. Hand and breast drills. GOLDNIAN, A. July 2, 1946, No. 19721. [Class 83 (iii)] In a hand drilling-tool having a handle by which the tool can be held in one hand and the working pressure applied by the same hand, the handle is formed to permit the mounting of a breast plate on the tool casing for use alternatively to the handle. The casing 1 has an integral spade handle 9 with a hole 28a through which a rod 28 carrying a breast plate 27 can be passed and secured to a socket 29 on the casing by a bolt 31. A handle 32 may also be screwed into the casing. The tool spindle 8 is rotated by a bevel wheel 3 which closes the aperture 2 in the casing and has a handle 6. Two rings of teeth on the wheel engage two bevel pinions 12, 12a mounted on the spindle and spaced by a sleeve 22. Within the sleeve a sliding dog clutch 16 can be engaged with one or other of the pinions to provide fast or slow rotation of the spindle by means of an eccentric 17 on a shaft 18 rotatable with a snap action by a knob 19. The eccentric can be withdrawn from the clutch against a spring 24a and the knob has a locating mark co-operating with " fast " and " slow " indications on the casing. An idler pinion 26 is also provided.
