Abstract

1,128,623. Intermittent gearing. FAIREY ENGINEERING Ltd. 15 Dec., 1965 [16 Dec., 1964], No. 51227/64. Heading F2Q. An intermittent rotary drive, e.g. for indexing a magazine of a fuelling machine for a nuclear reactor, comprises, secured on a drive shaft 21, a pinion 20 which engages toothed sectors 17 on a driven member 10 to drive the latter at constant speed between dwell periods, a roller 23 engageable with substantially radial slots 15 in the member 10 to decelerate and accelerate the member 10 immediately before and after the dwell periods, and a cam 24 which holds a pawl 13, radially movable in a fixed guide 14, in locking engagement with a notched block 11 secured to the member 10 to hold the latter during the dwell periods. Inlet and outlet slots 16 in the member 10 allow passage of the roller 23 while the pinion 20 meshes with a sector 17.
