Abstract: 837,432. Snap-action switches; retractive switches. MASON ELECTRIC CORPORATION. July 4, 1956, No. 20688/56. Class 38 (5). The moving contact of a switch moves along a path having recessed contacts under the action of a snap-action means connecting the contact and the actuating means and arranged to bias the contact into engagement with the path and to snap over centre as the contact is moved in and out of a recess. The contact path 30 has two rows of contacts 34, 36, 38 with insulation between, each contact having a recess 40, 42, 44 which is not as wide as the contact. The moving contact roller 32, comprising a conducting sleeve on a magnetic core bridges the two rows of contacts and is mounted in a cage 72 which can move freely, towards and away from the contact path 30, in a carrier 62. A snap-action spring 58 between the cage 72 and carrier 62 urges the roller 30 against the contact path and the carrier 62 is held in a spring 64 attached to an operating handle 60. When the handle 60 is operated the force exerted by the spring 58 retains the contact roller 32 in a recess until the spring 64 is strained sufficiently to cause the spring 58 to snap over and allow the roller to move to the next recess and it will then be moved into the recess with a snap-action. A member 96 is mounted on the handle so as to limit the " lost-motion " of the spring 64. A spring 102 can be fitted to return the moving contact assembly to the central position when the handle 60 is released. In Fig. 10 the moving contact assembly is mounted in a rotor and the contact path is a complete circle. The rotor shaft 252 is operated by a lost-motion drive and the roller contact carrier 284 is retained by shoulders on a member 244 against the snapaction spring 248. U.S.A. Specification 2,684,843 describes a suitable snap-action spring. Specifications 837,433, 837,434 and 837,435 also are referred to.

Abstract: 222,627. Hollingworth, E., (Crompton & knowles Loom Works). Aug. 20, 1923. Pile-fabric looms; creel-frame arrangements.- The tube frame 44 is supported, during the insertion of pile yarn, by a carrier 40 mounted on and extending across the loom from one tube end holder 18 to the other. The carrier is formed of two heavy metal plates 41, 42, a part 46 of the plate 41 extending through a loop formed by a plate &c. 45 near the middle of the tube frame 44. The part 46 fits in an opening. 47, and the plate 41 has a flange 43 extending under the tube frame. The rear plate may be cut off near its ends, the longer plate 41 being attached to the inwardly-projecting portions 50 of the holders. As successive tube frames are presented by the transporting chains to the usual arms 15 and holders 18, levers 33 are caused to actuate slides 32 to release the hooks 31 from the chains so that a tube frame may be freed therefrom and be deposited in the holders 18, and be firmly supported by the carrier 40.

Abstract: 352,490. Vehicle brake and door controlling apparatus. TOMLINSON, A. V., 65, Victoria Street, London.-(Compagnie des Freins Westinghouse ; 23, Rue d'Athenes, Paris.) April 10, 1930, No. 21247/29. [Class 103 (i).] Apparatus for controlling the operation of the brakes and doors on automobile vehicles and the like comprises a pedal or lever, the release of which effects an automatic application of the brakes and a release of the door-closing mechanism or a positive opening of the door in accordance with whether the vehicle is being driven or not. The opening of the doors depends on the position of the change-speed lever. The pedal 4 operates a rotary valve 6 cavities 14, 22 in which are adapted respectively to connect the cylinder 8 of the door engine to atmosphere and the cylinder 7 to vacuum or vice versa. When the vehicle is stationary a valve member 23 of a control valve 17 is held on its lower seating by a cam 28 on the gear lever when it is in neutral position. A bolt 32 connected to the pedal 4 locks the gear lever in this position when this pedal is released. In this position of the pedal also the cylinder 7 is connected through pipes 16, 20 and the valve 6 to a pipe 2 from the vehicle engine induction pipe, and the door is held open. The brake cylinder 1 is also connected to vacuum through a restricted aperture 39, pipe 25 and a double check valve 26, and the brakes are thus applied. To start the vehicle the pedal 4 is depressed reversing the connections to the door engine by means of the valve 6 and thus closing the doors and the air admitted to the cylinder 7 also releases the brakes by means of the aperture 39. The bolt 32 is retracted and the gear lever can be moved and allows the valve 23 to move to its upper position. If the pedal 4 is released while the vehicle is running it performs only a partial movement as the bolt 32 engages the boss 30 of the gear lever and both cylinders 7, 8 are connected to vacuum allowing the door to be opened by hand. The valve 23 is moved to its lower position during this operation by the vacuum below the diaphragm 18. The brakes also are applied through the aperture 39. A safety cock 34 can be operated by the passengers while the vehicle is running to connect the cylinder 7 and the brakes through the pipe 33 to vacuum. When the vehicle is stationary the pressure in the cylinder 7 is controlled by the driver only, by means of the valve 6 in view of the position of the valve 23. In order to render the closing action of the door engine free from shock a spring-controlled projection 35 is adapted to close the vacuum port 36 leaving open a restricted byepass 37. A vacuum reservoir may be provided as in Specification 306,880, [Class 103 (i), Brakes &c.], The brakes are normally applied by means of a pedal 3 and through a pipe 38 and the check valve 26.
