Abstract
424,473. Variable speed gearing. GAMBIN ET CIE, and MASSOT, P., 128, Rue du Point du Jour, Billancourt, Seine, France. July 18, 1934, No. 21028. [Class 80 (ii)] [See also Group XXII] A machine tool with a variable-speed drive is stopped by applying braking action simultaneously in front of and behind the variablespeed gearing. A shaft 15 geared to, say, a milling-machine is driven through variablespeed gearing of any kind from a shaft 8 driven through a friction clutch 10 from an input bevel gear 6. Springs 11 hold the clutch 10 engaged as long as the drive is required, and a sleeve 3 of the clutch is splined on an inner sleeve 9 keyed to the shaft 8. To stop the machine, the sleeve 3 and a sleeve 4 splined on the shaft 15 are simultaneously thrust left. This first opens the clutch 10 to interrupt the drive, and then brings cone brakes 26, 28 simultaneously into engagement with fixed cones 27, 30, respectively, so that the braking action is applied to both the shafts. A train of pick-off change gearing 18, 19, 20, 21, 22 is shown connecting these shafts. An arrangement of twin spring levers is described controlled by a device for effecting the simultaneous throwing over of the sleeves 3, 4.
