Abstract

474,056. Percussive tools. WARSOP, H. E., and WARSOP PETROL DRILL & TOOLS, Ltd. April 27, 1936, No. 11895. [Class 124] In an internal-combustion percussive tool in which the explosion takes place between a controlled piston and a free piston b, the latter is returned by a spring c. It is cushioned at the outer and inner ends of its strokes since its flange closes parts d and h respectively. The lower end of the cushioning space is closed by an anvil block e which is cushioned by air at the outward limit of its stroke. Specification 356,572 is referred to.
