Abstract

377,676. Percussive tools. SCOTT, T. R., 162, Harvest Lane, and WHEATLEY, A., 74, Woodside Lane, both in Pitsmoor, Sheffield. March 21, 1931, No. 8695. [Class 124.] A percussive tool has a crosshead H oscillated by a crank connected by springs K to the tool holder M, which fits upon a helically-splined spindle Q<1> secured to the crosshead H provided with pawl and ratchet mechanism R therein. The springs are secured to sleeves J, L, mounted on the members H, M. Stops N or O, O<1> may be provided to limit the stroke of the tool. The chassis A may be fed by screws B or the machine may be adapted as a hand tool.
