Abstract

827,560. Chucks. BERTHOLD, L. Aug. 15, 1957 [Oct. 19, 1956], No. 25799/57. Class 83 (3). In a chuck, jaws 5 are closed by compressionsprings 3 acting on a plate 2 integral with a tapered-collar 4 which engages the jaws; and the jaws are opened by oil-pressure admitted through a duct 8 to a cylinder 9, in a non- rotatable cylinder 6, to move a piston 7 engaging pins 10, which engage the thrust-plate 2. A sleeve 11, mounted on the cylinder 6, engages a shoulder 12 of the chuck body 1 to provide an abutment for the cylinder when pressurized; and a number of spring-urged pins 16, engaging the machine headstock, operate, when the pressure is released, to displace the cylinder so that the sleeve 11 is clear of the shoulder 12 during rotation of the chuck. The cylinder- and-sleeve assembly is slidably enclosed by a retaining ring 13. The ring 13 is attached to a headstock (not shown), by screws 14, and the body 1 is attached by screws 17 to a base 18 secured by screws 19 to the spindle 20.
