Title: Improvements in variable speed gear
IPC: F16H3/48
Filed: 1926-11-17
Abstract: 285,558. Rushfirth, S. Nov. 17, 1926. Variable-speed epicyclic gearing comprises a planet-carrying gear box i, Fig. 1, with a combined clutch and brake member m slidably splined thereto outside and biased by a spring n to hold the clutch m<2> in engagement so as normally to yield a high-speed solid drive. The member m<2> engages a female clutch member d fast on a driving-shaft c'. When the member m is thrust to the left by suitable means t, the clutch is disengaged and a flange m<1> is pressed with braking effect against a fixed friction surface b<2>. The carrier box i is thus held against rotation and a lower speed is transmitted. Two such gears are shown in series in Fig. 1, the one on the left yielding a reduced speed only, the one on the right a reversed drive as well. In each of these is a pair of stepped planets k, l meshing with gears e, h on driving and driven shafts respectively, the train e, k, l, h being operative for reduced speed. In the form on the right this train is designated e<1>, k<1>, P, h<1> and reversed driving is effected by sliding the gear h<1> out of mesh with the gear l<1> into mesh with an idler s<2> driven from the gear k<1>. In Fig. 5 is shown a form of gear which may be arranged within the carrier box i and yields three forward speeds and one reversed drive. There is the solid drive, and the first reduced speed through train e', k<1>, l<1>, h<1> as before. A gear h<2> loose on the end of the driven shaft c<2> constantly meshes with an additional planet o. The second reduced speed is effected by sliding the gear h<1> until the clutch face engages a clutch face on the gear h<2>. The reverse is effected in the configuration shown through an idler s<2> as before. In Fig. 7 is shown a form adapted as an auxiliary series two-speed gear upon a vehicle. A coupling flange is shown at w for driving a change-speed gear of any type. A toothed rim v is for starting the engine.

Abstract: 716,767. Road-vehicle spring-suspensions ; rubber springs. FORD MOTOR CO., Ltd. Nov. 20, 1952 [Jan. 10, 1952], No. 29389/52. Classes 108(2) and 108(3) A resilient bumper has a wing 44 of relatively narrow width extending outwardly from, and at an angle to the base portion 34. As shown in Fig. 2, the bumper is of rubber and has two wings 44 inclined at 70 degrees to each other. There may be only one wing, Fig. 8, (not shown), or there may be four, Fig. 12, (not shown). In Fig. 2, the base 34 has a slot 38 of T cross-section extending lengthwise of the damper. A slightly arched plate 47 extends through the slot 38 and is bent down at each end to form flanges which are bolted to the base 14 of the bumper. The slot 38 has a rib 56 to assist in preventing nipping of the rubber. In a modification, Fig. 9, (not shown), the downturned ends of the plate 47 are formed with ears which are bent to engage openings in the opposed legs of a U-shaped bracket. The base of the bracket engages the base 34, and the outer ends of the legs are flanged. In a modification of the latter construction, Fig. 10, not shown), the plate 47 and T-shaped slot 38 are dispensed with. The base of the U- shaped bracket has a rectangular-shaped aperture through which a part of the rubber base portion extends. This portion is enlarged so as to be clamped in position by the U-shaped bracked against the surface .to which the latter is bolted. In a further modification, Fig. 12 (not shown), there is no slot 38 but a longitudinallyextending projection engages by means of a reduced neck-portion an aperture in the base of the U-shaped member. As applied to a vehicle laminated spring suspension, the base 14 or U-shaped bracket, are bolted to the vehicle frame in a position so that following a predetermined deflection of the spring, the wing or wings 44 will engage the axle housing. Fig 1. (not shown). Alternatively, it may be positioned so that the wings engage the top leaf of the spring at a point intermediate its forward ananchorage and the axle. Fig. 11 (not shown). In operation, initial engagement of the wings 44 causes them to bend over at a comparatively low rate. When the wings engage the part 30 the rate sharply increases Characteristic curves of operation are shown. The bumper may be made by cutting off sections from a length of extruded rubber.

Title: Improvements in or relating to apparatus for controlling a helicopter in azimuth
IPC: G05D1/08
Filed: 1948-11-12
Abstract: 698,031. Automatic control systems. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Nov. 12, 1948 [Nov. 14, 1947], No. 29404/48. Class 38 (iv). [Also in Group XX] Apparatus for the azimuth control of a helicopter having a steering propeller comprises a gyro responsive to the velocity of the helicopter about its turn axis for controlling pitch changing mechanism of the steering propeller and means for controlling the response of the gyro to the turn velocity. In Fig. 4 a lifting rotor LR of a helicopter and a reversible-pitch steering propeller SP, mounted aft with axis athwartships to prevent rotation of the fuselage, are each driven through a transmission 24 from an engine E, the lifting rotor being driven through a free-wheeling unit 24a. Pitch of the lifting rotor is under the control of two handles 27, 28 associated with a pitch control unit. Handle 27 also controls the engine throttle and ensures a lifting rotor pitch suited to the throttle opening. Handle 28 may be moved from a central position in the direction in which it is desired to travel to produce a cyclic variation of blade angle, during revolution of the lifting rotor, from a maximum at one point to a minimum at a point 180 degrees therefrom so that the rotor thrust has a horizontal component producing travel in the desired direction. Turn of the craft in azimuth is prevented by a rate-of-turn gyro (see Group XX), responsive to angular velocity and acceleration about a vertical axis, precession of which controls the position of a pair of contacts C1, C2 relative to a contact C3, vibrated by slight unbalance of the gyro rotor, to control the relative energization of opposed fields DF1, DF2 of a D.C. generator GEN so that a motor M supplied from the generator effects the appropriate adjustment of steering propeller pitch. The orientation of the craft in azimuth and hence its direction of travel may be set by operating pedals 29 to move the slider of a potentiometer P from its normally central position until the torque applied to the gyro by the differential adjustment of the energization of electromagnets P1, P2 establishes a new datum position. In a modification, Fig. 5 (not shown), gyro contacts C1 C3 only are used to control the energization of a spring-biased solenoid-operated valve of a hydraulic system controlling steering propeller pitch. In this arrangement to reduce the duty on the contacts the energization of a further winding of the solenoid-operated valve is made dependent on the throttle setting.
