Abstract

294,414. Thompson, G . H. Aug. 27, 1927. Divided on 294,331. Percussive hand-tools.-A portable percussive hand tool comprises a rotary block b driven by a flexible shaft (not shown) and containing one or more radial recesses h each with a ball or like member j which delivers blows on a tool head or transmitting rod m which projects through a grooved liner l when the tool is pressed on the work. The travel of the rod m is determined by key plates t adjusted by nuts u and adapted to engage recesses in the rod.
