Abstract

597,864. Percussion tools. PHILIPPOVIC, J. W. Jan. 24, 1946, No. 37671. Divided out of 597,859. [Class 124] In a pneumatic percussive tool the socket member 3, the motor cylinder 1 and the cylinder head unit 5 are held together by elastic tiebolts 8 connected to the socket member and to the cylinder head unit. The tie-bolts may be formed from circular section spring steel rod bent into a helix 11, the axis of which is substantially perpendicular to the longitudinal axis of the bolt, as shown in Fig. 2, or into a smooth curve of at least half a wave, as shown in Fig. 3. The motor cylinder 1 may be formed with grooves 12 and flats 13 to accommodate the straight and bent portions, respectively, of the tie-bolts. To minimize the formation of ice around the exhaust ports 14, the latter are arranged in pairs, the axes of each pair converging downwardly towards each other. The cylinder head unit may be formed with downwardly inclined handles 15 as described in Specification 597,859.
