Title: Gear train for toy vehicles
IPC: A63H17/06
Filed: 1968-02-08
Abstract: 1,214,943. Toy vehicle. WONG MING NGAI. 10 Feb., 1969 [8 Feb., 1968], No. 6298/68. Heading A6S. [Also in Division F2] The wheels of a toy vehicle are actuated by the movement of a segmented cogwheel which engages, via idler cogs, with a cog secured to an axle of the vehicle, the arrangement being such that the movement of the segmented cogwheel in forward and reverse directions causes an idler, fixed to a shaft mounted at two spaced portions for lateral movement in two slots, to be carried in and out of driving contact with the cog on the axle of the vehicle. The motive power for the segmented cog-wheel may be provided by a spring compressed by moving a part of the vehicle. In Fig. 1 a spring (not shown) causes container 1 of a toy dumper truck to pivot about 3 away from chassis 2. Depression of 1 towards 2 compresses the spring and moves segmented cogwheel 4 downwards (reverse direction). Sets of cogs 6, 7 and 8, 9 rotate to cause a shaft bearing cogs 10, 11 to be moved in slot 12 to disengage cog 11 from cog 13 secured to an axleof driving wheel 14. Release of pressure on container 1 with consequent release of the spring causes reverse movements such that the shaft bearing cogs 10, 11 is moved in slot 12 so that drive is transmitted to cog 13 from cog 11. The slot 12 extends radially of cog 13 in a direction parallel to a tangent of cog 9. Each pair of cogs 6 and 7, 8 and 9, 10 and 11 is constructed in a plastics material formed as a unit 16 (Fig. 2) and located on a metal axle by means of sleeve 15 to lessen the risk of slipping.

Title: Improvements in or relating to frictional driving clutches
IPC: F16D43/12
Filed: 1941-05-16
Abstract: 545,751. Friction clutches. BORG & BECK CO., Ltd., and GODFREY, L. P. May 16, 1941, No. 6363. [Class 80 (ii)] In a plate friction clutch having releasing levers 20 which are pivoted at 22 to a member 23 fixed to a cover 11 and in which a thrust transmitting member 30 engages the levers..20 and an overhanging lug 33 on the pressure plate 10 for declutching, the levers 20 engage a second thrust transmitting element 38 to force the pressure plate more firmly into the clutch engaging position. The clutch is of the kind in which springs urge the pressure plate towards the engaged position. As shown, each lever 20 has a weight 35 secured thereto so that when the clutch is engaged, the centrifugal force of the weight acts on the lever and thrust transmitting element 38 to increase the clutching force. The member 38 is formed as a screw and is adjustable on the pressure plate 10. The thrust member 30 is a plate of T-shape. The pivot 22 of each lever 20 is carried by a member 23 supported by a screwed adjusting member 26 carried by the cover 11. Anti-rattling springs 42 are fitted. Specification 456,925 is referred to.

Abstract: 525,762. Electric cables. BEAVER, C. J., DAVEY, E. L., and GLOVER & CO., Ltd., W. T. Feb. 28, 1939, No. 6564. [Class 36] In cables with concentric conductive layers such as f, g, h arranged at various radial distances from the conductor G, each layer is produced by the helical winding of two strips of metallized insulating material. The metallic portion of each strip is narrower than the whole strip, the first strip is lapped on helically with the metallic surface outside and a small space left between adjacent turns and the second strip is then applied with the metallic surface inside and covering the above spaces. The material used for the strips as well as for all the intervening insulating strips is preferably paper impregnated before being wound and there is preferably gas in the spaces between the turns and layers.

Abstract: 676,257. Variable-pitch propellers. UNITED AIRCRAFT CORPORATION. March 21, 1950 [March 30, 1949], No. 6993/50. Class 114. Blade settings are varied by the vane motors 30, fluid for which is supplied by pumps 34 rotating with hub and engaging the cam 40 which is normally stationary. The fluid is controlled by valve 38, the position of which is controlled by the plate 58, whose axial position is determined by rotation of the member 130 and cam slot 134, the member being rotated about the shaft axis bv rack 108 under control of servomotor 80. Fluid for the servomotor is supplied by pump 96 and controlled by governor valve 92 to maintain constant speed. For feathering and reverse with shaft running the electric controlled valves 104, 144, 146 are operated to cut out the governor valve and direct fluid from pump 96 to the servomotor. For feathering the blades with the shaft stationary the cam 40 is rotated about the shaft by the motor 78, thus operating the pumps 34. Under these conditions auxiliary pump 158 supplies fluid to operate the servomotor. Specifications 560,522 and 670,412 are referred to.

Abstract: 1,240,565. Hoist brakes. EATON YALE & TOWNE Inc. 12 Feb., 1969 [9 July, 1968], No. 7560/69. Heading B8B. [Also in Division F2] A self-sustaining arrangement in the form of a Western mechanism, in a hoist, includes a ratchet disc 15 having friction material 18 of substantially the same dynamic and static coefficients of friction bonded to opposite faces thereof and engageable during hoisting and to prevent lowering of a load, by a pressure disc 14 on a load shaft 11 and a hub 13, the latter threadedly engaging a screw portion 12 of the shaft 11. The arrangement runs in a bath of oil which circulates for cooling purposes through passages in the discs 14, 15 and the hub 13, and along grooves 19 on the friction material 18 and grooves 21 on the surfaces 113, 114 of the hub 13 and disc 14. The surfaces 113, 114 are finished to 10 micro inches, which with the friction material 18 bind and unbind without any erratic gripping and releasing action whereby the lowering of a hoist load can be performed smoothly, frictional contact between the material 18 and surfaces 113, 114, being maintained throughout. In operation, the hub 13 is driven by a gear-wheel 27 on a drive shaft 26 in one direction to screw the hub on the thread 12 into binding relation with the disc 14 and ratchet 15, which free wheels in this load-lifting direction, and the hoisting shaft 33 is driven through gearing 32, 31, 30, 29 from the load shaft 11 to which the disc 14 is secured. The load is lowered by reversing the drive on the hub 13 whereupon it unscrews on the portion 12 and unbinds the ratchet disc 15 which is prevented from rotation in this direction. Rotation of the load shaft 11 due to the lowering of the load tends to screw the hub 13 back into binding relative with the ratchet disc 15 which causes the lowering to be braked if the reverse drive to the hub 13 is stopped.
