Title: Improvements in or relating to variable speed gears
IPC: B62M11/14
Filed: 1921-06-14
Abstract: 177,737. Bartlett, B. G. June 14, 1921. Variable-speed epicyclic gearing suitable for motor-cycles comprises an element n, Fig. 1, which is braked to produce varying speeds with varying amounts of slip, and is adapted to be moved out of mesh so as to diminish friction when, say, a cycle is being manually propelled. A driven pulley g carries spindles e each having at one end a pinion o adapted to mesh directly with the gear n. At the other end of each spindle e is a wheel d meshing with an idler c carried by the pulley boss f, which in turn meshes constantly with a pinion b fast on the driving-shaft a. The gear n is secured to a sleeve m loose upon the shaft a. Upon the sleeve m between a shoulder t and a nut u is clamped a conical brake member q. A cap w turns on the boss of the brake q and is adapted to be moved against the resistance of a spring x so as to press the brake q against a fixed cone k so as to allow varying amounts of slip and so to control the speed ratio. When the cap w is thrust to the left, the brake q disengages the cone k, stopping the drive. On further movement, the gear n is withdrawn from mesh with the gears o. The terminal speed obtained by stopping the brake q may be altered by changing the gears in the train.

Title: Improvement in and relating to the manufacture of electric lamps
IPC: H01J9/30
Filed: 1952-06-30
Abstract: 720,426. Making electric lamps and similar devices. BRITISH THOMSON-HOUSTON CO., Ltd. June 30, 1952 [June 30, 1951], No. 16402/52. Class 39 (2) A leading-in wire 3 extendirig upwardly from the bulb or envelope 1a of an electric lamp or similar device prior to capping is set in readiness to receive a cap by a device comprising a pair of scissorlike arms 24, 25 (the latter being shown with an intermediate break in Fig. 1) pivotally mounted for movement in a horizontal plane upon a crosshead 26 which is mounted for vertical reciprocable movement, the operative ends of the scissor arms being provided with resiliently-mounted gripping members which grip the leading-in wire whereupon the crosshead is moved upwardly to stress the wire and set it into a straight vertical position. The crosshead 26 is guided by a pair of vertical rods 30, 31 supported by a rigid block 32 and is reciprocated by vertical movement of a spindle 35 linked to a cam-controlled connecting rod 36, the spindle 35 being slidable within the crosshead and provided with a pair of fixed collars or stops 37, 38 spaced to provide a lost motion before impinging on the crosshead to effect upward or downward movement of the latter. A wedgeshaped member 39 mounted on the upper end of the spindle 35 is arranged to engage rollers 40, 41 on the extremities of the scissor arms 24, 25 to effect the closing of their operative ends against the tension of a spring 29 connected between the arms rearwardly of their pivots 27, 28. Fig. 3 shows the outer or operative ends of the arms 24, 25 which carry inwardly directed V-shaped combing members 20, 21 and, above those, a pair of gripping members 22, 23. The combing members are so dimensioned that, when closed, they confine the wire within the apices of the notches without gripping it. The gripping member 23 is fixed rigidly to the arm 25 by a bracket 60, but the co-operating member 22 is mounted on a pivot 62 carried by a fixed bifurcated bracket 61 and has an arm connected to a tensioned spring 63 which tends to swing the member 22 forwardly, this effect being controlled by an adjusting screw 64. The co-operating gripping faces of the members 22, 23 are at 66 and 67 respectively, and the member 22 is adjusted so that it is forced to pivot back slightly when the scissor arms swivel together. Thus the leading-in wire is gripped and given a sharp pull when the crosshead 26 moves upwards. As shown, the bulb holders comprise a series of pairs of jaws 6, 7 pivotally mounted on base plates 5, the undersides of which are secured to an endless chain conveyer 11 operating between a pair of track rails 12, 13.

Abstract: 202,780. Little, J. June 14, 1922. Casings; regulating.- A centrifugal pump has means for controlling automatically the effective delivery area of the impeller so that the quantity of fluid is approximately constant when the head against which the pump is working is decreased. The casing is in two parts 1, 2 which carry the inlet 3 and delivery 4 respectively. An inner rotatable casing has portions 5, 6 the former 5 of which carries impeller blades 7 which are also attached to a plate 8 secured to the end of the driving shaft 9. A diffusion chamber is formed by plates 13, 14; the plate 14 is carried by arms 24 on the bearing sleeve 16 and the plate 13 with its peripheral flange 27 is carried by the rod 15 which can slide in the sleeve 16 but cannot rotate. The outer end of the rod has a piston 17 working in a cylinder 18 under the control of a spring 22 which can be adjusted by the screw 20 and the slide 21. The cylinder 18 is in communication with the pump delivery through the channel 23. When the pump is working the piston 17 occupies a position in which the delivery pressure is balanced against the spring pressure; as the head decreases the spring moves the piston and this operates the diffusion plate 13 and its flange 27 over the effective delivery area of the impeller thus keeping the quantity approximately constant. Apertures 25 are provided in the parts 5, 6 to equalize the pressure in the impeller chamber and in the surrounding casting. Similar apertures are provided in the plate 13.
