Filed: 1935-02-26
Abstract: 452,590. Ships' steering-gear. DONKIN & CO., Ltd., PAULIN, W. S., and STOREY, E., Walker Gate, Newcastle-on-Tyne. Feb. 26, 1935, No. 6076. [Class 114] [See also Group XXIX A hydraulic-control apparatus has the motive fluid supplied by a single pump adapted either to be driven by power or operated manually. The Figure shows the invention applied to a hydraulic steering-gear for ships. The rudder 8 is operated by a pair of rams 5, 6 working in opposed cylinders 9, 10 connected by pipes 11, 12 with a variable capacity pump 13. The driving shaft 14 of the pump is coupled by a hand-operated clutch 15 either to an electric motor 38 or to a sprocket 16 connected by chain 17 and sprocket 18 to the helm 20. The strokevarying mechanism of the pump is actuated by a shaft 25 coupled to the mid-point of a floating lever 53 linked at one end to a pair of rams working in opposed cylinders 47, 48 and at the other to a worm quadrant 56 meshing with a worm 61 rotatable by a hand wheel 57 acting through bevel gearing 59. An indicating pointer 35 is operated by a worm on the hand-wheel shaft or may be operated electrically. The cylinders 47, 48 are coupled by pipes 45, 46 and valve 63 to a similar pair of cylinders housing a pair of plungers connected by a link 42 to an arm 7 on the rudder. When it is desired to change to manual operation the motor 38 is disconnected, the hand wheel 20 coupled up, and the hand wheel 57 operated to move the member 25 so as to impart stroke to the pump, the member 25 being subsequently locked in this position by a pin inserted in hole 62. To allow the rams 40, 41 to idle during manual operation the valve 63 is moved to connect the four cylinders 43, 44, 47, 48 to a make-up tank 64 the quadrant 56 may also be disconnected from its actuating arm. In a modification having no follow-up mechanism the hand lever for operating the clutch is interconnected with the switch controlling the pump motor. The handle for operating the stroke varying mechanism acts through two sets of bevel gears and a pinion and rack, the shaft carrying this pinion being provided with a hand lever and locking device whereby the pump control may be looked away from its neutral position during hand operation of the pump.

Title: Improvements in or relating to change-speed transmission control system
IPC: F16H63/30
Filed: 1956-02-28
Abstract: 801,549. Change-speed control. STUDEBAKER-PACKARD CORPORATION. Feb. 28, 1956 [Aug. 1, 1955], No. 6145/56. Class 80 (2).  A direct-, under- (or over-) drive two-speed gear on a vehicle is electrically controlled, through a relay switch 106, by the usual accelerator pedal 34 and by an output-driven centrifugal governor G, which actuate switches- SW3, SW4 respectively, in parallel circuits each including a resistor R such that energization of the relay 106, to cause upshift, requires the closure of both switches SW3, SW4 together, whilst once the relay has been operated it is maintained operated by the continued closure of either one switch SW3, SW4 alone. Thus complete accelerator release, to close the switch SW3, will cause upshift providing the vehicle speed is above that (12-30 m.p.h.) required to close the governor switch SW4, and subsequent depression of the accelerator pedal, although reopening the switch SW3 will not cause downshift unless the vehicle speed falls to that required for reopening the governor switch SW4, nor will downshift be caused by re-opening of the governor switch SW4 on deceleration unless the accelerator pedal is within its normal range of movement, with the switch SW3 open. The two-speed gear may be that described in Specification 477,530, wherein upshift from spring-maintained reduced-drive to direct-drive is caused by supplying hydraulic pressure to an annular piston 58, which thrusts axially a reaction sun 46 to release an outer coned brake surface 52 thereon, and clutch an inner coned surface on an input ring gear 38, the gears meshing planets carried by an output shaft 16. Pressure liquid, pumped by an engine-driven pump 72 through a spring- or air-pressureloaded accumulator 78, is supplied to the piston 58 to cause upshift, when a ball valve 88 is opened through a plunger 90 and lever 94 by energizing a solenoid 98 through the relay switch 106. Included in the relay energizing circuit are also the engine-ignition switch SW1, a manual upshift lock-out switch SW2, and an accelerator kick-down switch SW5, closure of which latter causes downshift at any speed, providing the switches SW1, SW2 are also kept closed.

Abstract: 314,455. Rice, C. S. Feb. 28, 1928. Theft alarms.-In a device for preventing the theft of motor vehicles, the falling of an object such as a metal ball from a position in which it is normally supported, consequent upon movement or vibration of the vehicle, is utilized to render inoperative the ignition of the engine. As shown, a metal ball 3 is supported by a recessed platform 2 in a casing 1, and is normally held in position by a dished plate 4 mounted on springs 6 and depressed by a lever 7 pivoted in the top of the casing. Contact strips 10<a>, 11<a> in the casing are connected respectively to earth and to the ignition magnets, and contact strips 10<b>, 11<b> to a battery and a horn or bell 13. When the lever 7 is thrown over to release the plate 4 from the ball 3, movement or vibration of the vehicle will cause the ball 3 to fall on the contact strips, earthing the magneto and completing the circuit of the horn 13. In a modification, for an engine having battery ignition, the ball falls on and tilts a spring-controlled pivoted contact-plate arranged to break the circuit of the induction coil and to close the circuit of a horn.
