Title: Gear for washing machines
IPC: F16H61/02
Filed: 1964-10-07
Abstract: 1,045,814. Change-speed gear; friction and ratchet clutches. FICHTEL & SACHS A.G. Oct. 7, 1964 [Oct. 8, 1963], No. 40882/64. Headings F2C and F2D. [Also in Division D1] A two-speed gear in a washing machine comprises an input shaft 1 driving a sun-gear 3 meshing planet pinions 5 in turn meshing a reaction ring-gear 4, a step-down drive being obtained for washing from the carrier 7 through a roller ratchet clutch 11 and a shaft 2 mounting a driven pulley 14. For spin drying, the speed of a motor powering the input shaft 1 is increased, so that a mass 17 at the end of a shaft 15 rotating with the input shaft flies centrifugally outwards against the bias of a spring 22. The mass 17 is engaged by the end 32 of a helically coiled clutch spring 19, secured to the enlarged end 16 of the shaft 15. As the mass 17 flies outwards, it abuts a tab 21 at the end of a coil spring 20 frictionally gripping the hub of the driven pulley 14, which is rotating at the slower speed of the planet carrier 7. The helical coil clutch spring 19 is then contracted onto the end of the shaft 2, provided it is rotating in the correct direction, and direct drive is obtained, the ratchet clutch 11 over-running. The ratchet clutch 11, Fig. 3 (not shown), comprises rollers in a cage 12 restrained against rotation by a light friction drag spring 13. The rollers lie within pockets in the hub of the planet carrier 7 and engage the cylindrical outer surface of the shaft 2. Thus rotation of the planet carrier 7 in either direction transmits drive to the shaft 2, whereas the shaft 2 can rotate freely in either direction relative to the planet carrier 7.

Abstract: 946,754. Making lamp bases; jointing by forging. SYLVANIA ELECTRIC PRODUCTS Inc. Dec. 8, 1959 [Dec. 15, 1958], No. 41776/59. Headings B3A and B3H. [Also in Division H2] A method of making a base assembly for an electrical device which includes an insulating plate having an aperture therein and a pin having a beaded shoulder intermediate the ends thereof, comprises the steps of positioning the pin in the aperture with the shoulder abutting one surface of the plate, crimping the pin adjacent the other surface of the plate and simultaneously pressing the plate against the shoulder, the crimping causing lateral spreading of the pin over the other surface of the plate. An apparatus for performing the method comprises a pin staking assembly 26 mounted in the ram 20 of an arbour press. The assembly 26 comprises a cross-bar 28 and a pair of arms 30 pivoted on pins 32 and limited in their movement by pins 34 extending through elongated slots 36 in the cross-bar. The insulating plate 1 with the pin 3 is positioned on a jig 24. As the ram moves down the arms 30 contact the top surface of the disc and close on to the sides of the pin, simultaneously the downward thrust of the ram presses the disc 1 against the shoulder 5 on the pin. After the pin has been staked the crimped end is formed to a tab by the device 30 shown in Fig. 6, in co-operation with a spacing anvil 40 which is slipped over the jig 24. The device 38 comprises a sleeve 44 attached to the ram 20 and containing a spring- loaded plunger 46 which is retained by a cam 50 attached to the sleeve. On the plunger 46 is bracket 52 on which a rocket arm 56 is pivoted by a rod 54 and mounted on the rocker arm is a cam follower 58 and a flattening iron 60. A flat spring 62 biases the follower against the cam. A stop screw 66 limits the movement of the rocker arm. As the ram moves downwards the flattening iron first deflects the pin 3 and then rotates clockwise to bend it over, and as the rotation of the arm is stopped by the screw 66 the last part of downward movement of the ram results entirely in compression of the tab. Specification 946,751 is referred to.
