Abstract

294,331. Thompson, G. H. May 31, 1927. Percussive hand-tools.-A portable rotary and percussive tool for boring coal, rock or the like comprises a drill chuck 18 rotated by worm gearing 20 from a flexible shaft attached to a spindle 3, within which chuck is adapted to slide a rod 17 which is struck by a rotary hammering device 12 geared to the spindle 3 and comprising one or more balls 14 housed in a rotating block and adapted to strike the end of the rod 17 projecting through a hard steel grooved liner 15. The travel of the rod 17 is determined by key plates 28 adjusted along the chuck by means of nuts 30 and adapted to engage flats 27 on the rod through slots in the chuck. Specification 14971/11, [Class 83 (iv), Metals, Working], is referred to.
