Abstract: 676,901. Machine tool details. ARNOLD, J. C. (Benjamin, M. L.). Dec. 20, 1949, No. 32657/49. Class 83 (iii). [Also in Groups XXIV and XXXIV] An index fixture for machine-tools comprises a step-by-step ratchet mechanism operated by fluid pressure. A spindle 6, screw-threaded at 13 for mounting a chuck &c. is rotatably mounted in a housing 1 and carries a fixed ratchet-wheel 16 and a rotatable member 15. The member 15 carries a gear-segment 18, a lug 19 carrying a spring-loaded pawl 20, and an arcuate cam-plate 26 coacting with a spring- pressed plunger 29. The plunger 29 locks the ratchet-wheel 16 when released by the cam 26 at the end of an operative (clockwise), indexing stroke. Counter-clockwise movement of member 15 is limited by engagement of the lug 19 with a pin 41 inserted in one of the openings 42. A spring-loaded holding pawl 37 for the wheel 16 is carried by an adjustable plate 39. The member 15 is oscillated by a piston-rod 48 having annular grooves 49 engaging the gear segment 18, the rod being reciprocated by pistons 46, 47 of different diameters in cylinders 44, 45. The smaller cylinder 44 is permanently connected to a source of fluid pressure, the larger cylinder 45 being supplied with fluid upon actuation of a valve which may be controlled by the machine-tool. If a compressible fluid, e.g. air, is used, the cylinder 45 may be supplied through a needle-valve in parallel with a one-way check-valve to give a slow clockwise movement of the driving pawl 20 and thereby minimize shock on the locking plunger 29. In a modification, the end 28 of the plunger is parallel-sided and the ratchet teeth are provided with slanted portions to facilitate its entry therebetween, the plunger sliding in a bushing tapered to fit a tapered hole in the radial bushes 30, 31 so as to be self-locking therein.
