Title: Improvements in progressive change speed devices
IPC: F16H29/14
Filed: 1931-02-17
Abstract: 373,161. Variable-speed gearing; clutches. HENRIOD, C. E., Areuse, Neuchatel, Switzerland. Feb. 17, 1931, No. 5040. Convention date, Feb. 17, 1930. [Class 80 (ii).] Variable-speed and reversing ratchet gearing is of the type described in Specification 176,356, [Class 80 (ii), Gearing, Variablespeed &c.], in which a flywheel 3, Fig. 2, fast on a driving shaft 21 carries planet gears 12 meshing with a sun gear 7 on a driven shaft 8 and adapted to drive the same intermittently as the planet gears are locked to crank pins 9 drawn round in an eccentric recess 40. The invention comprises cam means for operating the intermittent locking between the cranks 9 and the planets 12, so that the speed of the shaft 8 can be varied from solid driving continuously down to zero and beyond that to effect reversal. Circular ribs 13 projecting from the wheel 3 support, on their outsides, the planet gear rings 12, and, in their insides, rocking bosses 4 each carrying a crank 9. Each boss 4 is locked to its planet 12 when a coned pin 5 is pulled outwards by a lever 19 as it sweeps round over a relatively fixed cam 24 operative for a quarter of a revolution. Each pin 9 projects from one of the bosses 4 into a shoe 39, Fig. 3, in the annular recess 40 in a revoluble member 38 running on a ball bearing 29 on a boss 28 forming part of a disc 26 which is turned to vary the speed. As the disc 26 is turned about a centre 27, the groove 40 moves from concentric position to positions more and more eccentric. Control is effected by turning a gear 34, through which screws a rod 33 joined to the disc 26. The control gear 34 engages a gear 37 carrying a rim cam 35 and a face cam 36. In the con. centric position of the groove 40, the cam 36, by acting on a striker 25, Figs. 1 and 2, has moved a sleeve 23 towards the wheel 3 so as to mask the cam 24 and hold the levers 19 with all the planetary locking devices operative, so that the gearing turns solid. As the groove 40 is moved eccentrically, the mask 23 is withdrawn, allowing the cam 24 to operate the locking devices in succession, and the cam 24 is moved . through a sleeve 20 by a rod 22 from the cam 35 so that each pin 9 is locked to its gear 12 when the pin is moving most uniformly. The speed of the shaft 8 is brought to zero and then reversed as the control gear 34 is turned. The locking device may comprise three segmental friction blocks 17, Fig. 1, carried by the oscillating plate 4 and thrust out against a return spring 18 by the coned pin 5 into gripping engagement at the selected movement with the hollow planet gear 12. The locking device may alternatively comprise floating toothed pinions 15 carried in the thickness of the disc 4 and meshing with inner teeth 6<1> on the gear 12 and with a segmental sun gear 16. The coned pin 5, by expanding the gear 16, spoils the toothed mesh and locks the parts solid.
