Abstract

1442104 Percussive drills SOC DE PROSPECTION ET D'INVENTIONS TECHNIQUES 9 Aug 1974 [10 Aug 1973] 35141/74 Heading B4C A power drill has a driving piston 1 driven from a motor 5 which piston is mounted in a cylinder 1 and separated by a compressible air space 4 from a driven piston 3, the piston 1 having a pin 15 which engages in a helical slot 16 in the cylinder 2 to cause rotation of the cylinder as the piston reciprocates, the rotation being transmitted in one direction only by a one-way clutch 14. The pin 15 may have a roller to engage an angularly adjustable ramp mounted on the machine casing so that the amount of twist given to the drill for each rotation can be varied. To allow for rotation of the pin 15 about the piston axis a ball joint 9 is provided in the machine drive.
