Title: Improvements in or relating to electric switches or circuit breakers
IPC: H01H73/30
Filed: 1936-03-23
Abstract: 472,496. Automatic circuit-breakers. CIRCUIT BREAKERS, Inc. March 23, 1936, No. 8691. Convention date, June 18, 1935. I-Class 38 (v)] In an automatic circuit-breaker of the kind in which the circuit-closing member is moved into the closed position against the action of a spring and is retained by holding mechanism which is actuated to trip or release the circuitbreaker on the occurrence of an overload, the switch-actuating member is entirely separate from the holding mechanism and is disconnected from the circuit-closing member during the final circuit-closing movement by the action of a member carried by a stationary part of the switch. In the construction shown in Fig. 1, the switch is mounted in a threaded plug 30 bearing a metal shell 52 and a central contact 31 connected to a spring contact 67 with which a movable contact 68 engages to close the circuit. The contact 68 is carried by a plunger 36 mounted in guide members 69, 72 and normally urged to the "off" " position by a spring 71. The switchactuating member comprises a button 74 carrying claws 76, which, when the button is pressed inwards against the action of a spring 80, engage the plunger 36 and carry the movable contact 68 into engagement with the contact 67. In this position a collar 70 on the plunger engages an opening in a spring plate 83, which grips the collar and holds the plunger in the circuit-closing position. As this position is reached, the nose 79 of a fixed sleeve 78 carried by the guide plate 69 engages the claws 76 and disconnects them from the plunger in order to provide a trip free release. The plunger is released on overload by the bending of a U-shaped bimetallic member 81 carrying the current ; it can also be released manually by a push button 86, both the member 81 and button 86 engaging the end of the spring plate 83. In a modification, Fig. 4, a bridge member 87 is slidably mounted on the plunger 36 and carries one or more indicators 89 which project above recesses 90 in the casing 66 when the switch is open. When the switch is closed, a spring 88 presses the bridge member downwards, and the indicators are drawn into the recesses. In another construction the bimetallic strip itself constitutes the detent device and carries a central ring adapted to receive and hold the collar on the plunger until the collar is released by the bending of the strip. In the construction shown in Figs. 8 and 12, an enlarged head 114 on the plunger 36 is adapted to be received in and held by bulges 113 on a pair of bimetallic members 110, 111 mounted in the base of the plug 30. On overload, the strips bend outwards to release the plunger, or they may be spread apart to effect the same result by means of a wedge member 124 operated through a bell-crank lever from a push button. To prevent arcing when the circuit is opened, a wiping contact 118 secured to the plunger, engages a stud 117 of high-resistance material and provides a shunt circuit during the first part of the opening movement.

Title: Improvements relating to hydraulic variable speed gears
IPC: F16H61/40
Filed: 1924-04-07
Abstract: 213,932. Kahlig, J., and Grazer Waggon-und Maschinen - Fabriks- Akt.-Ges. vorm. J. Weitzer. April 7, 1923, [Convention date]. Speed-varying mechanism.-Hydraulic variable-speed gears consisting of a pump and motor are provided with controlling means comprising a valve 1, which controls communication between the pressure and suction sides. The valve has a piston 3 working in a cylinder 4 supplied from the pressure pipe 6 through a non - return valve 8 and an adjustable needle valve 9, the other end of the valve being also acted on by pressure from the pipe 6 and being of less area than the piston. When a valve 14 or 15 is opened the cylinder communicates with the suction side of the gear through pipes 10, 13 and the reduction in pressure causes the valve to be opened. If the motor overruns the pump, the change in pressure conditions moves a slide valve 12 to place the pipe 10 through the slide valve in communication with the pump delivery, and the valve 1 is opened. The valves 14, 15 may be operated in any desired manner, e.g. from the level indicator when the gear is used in a hoisting plant, and one of these valves may be spring-controlled so that it remains closed only so long as pressure is exerted by the attendant. The areas of the piston 3 and valve 1 may be selected so that for different directions of movement of the motor the valve closes at different speeds, especially when the gear is used in hoisting plant having one rope only. The valve 1 is also opened when the pressure exceeds a predetermined limit, a valve 17 then yielding and putting the cylinder 4 into communication with the low pressure side.

Abstract: 562,576. Diaphragm pumps. TRIGGS, W. W. (Eisemann Magneto Corporation). June 26, 1942, No. 8827. [Classes 8 (i) and 102 (i)] A diaphragm pump for liquids or gases comprises a resilient diaphragm 12 having lateral rigidity, the central portion of which is coactive with the central portion of a peripherally supported leaf-like spring 30. The diaphragm and/or the spring may each consist of one or more flat or cupped spring steel laminµ, the diaphragm may be smooth or corrugated, and the spring may consist of a central hub with radiating arms. The periphery of the diaphragm is clamped between gasket rings 13 and its central portion is clamped by a nut 23, washer 24 and gasket rings 25 on a shoulder 21 on a bearing-free forked operating member 18 carrying a roller 19 for engagement with a cam 20, the operating member and roller passing freely through a hole 26 in the pump base member 10. The central portion of the spring 30 bears on the washer 24, and its periphery is supported by spaced seats 28 providing passages 29. The diaphragm 12 and the pump casing 14 define a pumping chamber 27 which communicates by relatively inclined check valves 42 with inlet and outlet chambers 37, 40 closed by removable caps 38, 41 which are fitted with flexible rubber diaphragms 54 to form pulsation-eliminating air chambers 53. Each check valve 42 comprises a leaf-like spring 46 which holds a valve plate 45 against a seat 44 on a sleeve-like cage 43 with a tapered throat 50. The cage 43 of the inlet valve is formed at the highest point of the annular recess surrounding the valve seat 44 with a hole 51 which co-operates with a slightly higher groove 52 cut at the highest point of the pump chamber 27 adjacent the throat 50 of the outlet valve, to provide for the escape of relatively light foreign fluids such as air or fuel vapour. The diaphragm 12 may be raised for priming purposes by means of a spring-controlled arm 65 on a shaft 60, the inner end 63 of which is machined off to form a pair of cam surfaces 64 which engage a shoulder 57 provided by a hole 58 formed in one leg of the roller fork 18.
