Title: Improvements in power-operated gear shifting mechanism
IPC: F15B13/06
Filed: 1934-11-07
Abstract: 439,075. Controlling variable-speed gearing; locking levers. BENDIX-WESTING- HOUSE AUTOMOTIVE AIR BRAKE CO., Pittsburg, U.S.A. Nov. 7, 1934, No. 31976. Convention date, Nov. 8, 1933. [Classes 80 (ii) and 80 (iii)] [See also Group XXIX] Fluid-pressure cylinders 19, 20 for selecting and operating, respectively, gear-striking rods 16, 17, 18, are controlled through valves 28, 29, 30, 31 by a ball-mounted hand lever 24, which moves in a gate 25 to simulate the movement of a conventional gear-shifter lever. To provide a degree of sensitivity, the valves offer a progressively-increasing resistance to the movement of the lever, and the striking-cylinder 20 is controlled through a follow-up relay 32, which gives it a movement proportional to that of the control-lever. The selecting- cylinder 19 acts, through a pair of antifriction balls, to rock a selecting-lever 86, rotatable on, but axially movable with the piston-rod 14 of the striking-cylinder 20. Both the selecting- cylinder 19 and the relay-cylinder 32 are selectively put in direct communication with the atmosphere or with a pressure-air tank 21 by the valves 28 .... 31, and the relay-cylinder 32 controls two valves 98, 99 which supply pressure-air to either side of the strikercylinder 20 from a separate tank 22. The valves 98, 99 constitute the follow-up control, their single body being rigidly mounted on the piston-rod 14 of the striker-cylinder, and they are operated by a common rocker 118 secured to the relay piston-rod 96, so that movement of the latter opens a valve and the subsequent follow-up movement of the rod 14 closes it. The cylinders 19 and 32 both have precompressed neutralizing springs. The main control valves 28-31 each comprise a piston 61, Fig. 2, loaded by opposed springs 64, 65 and such that, when acted on by the pressure in the outlet-chamber 52, the piston rises, thereby releasing a spring-loaded inlet valve 49, cutting off communication with a pressure chamber 47. The load on the operating spring 64 is thereby increased. This spring 64 is operated on by the control lever 24 through a camsurface 37 on the lever, an adjustable rocker 38 and a sliding cup 66. When released, the piston 61 vents the outlet-chamber 52 to atmosphere at 45 through a port 62 in the piston which is closed, when the piston moves downwardly, by an upper seat 59 on the inletvalve 49. The follow-up control valves 98 99 are of the same construction. The striker-rods 16-18 are located in gear and neutral position by a spring ball-detent. The valve-housing 28-31 is clamped to the steering-column of a vehicle. Levers, locking.-The control-lever 24 is locked in gear positions by a spring-loaded external sleeve 70, Fig. 2, engaging the bevelled sides of the gate, which sleeve must be grasped and pulled upwardly by the operator before he can move the lever.

Title: Improvements in coin-freed vending machines
IPC: G07F5/26
Filed: 1928-11-05
Abstract: 325,197. Dehn, F. B., (Mills Novelty Co.). Nov. 5, 1928. Delivery of articles stored in piles. - Relates to coin-operated vending machines of the kind in which there are a plurality of magazines, each with a separate ejector, and a single coin-controlled mechanism and in which a selected ejector may be actuated to effect the discharge of an article from its magazine while the remaining ejectors are held in locked position. According to the invention, a selector bar prevents the actuation of all but one of the ejectors, this ejector, after actuation, being held in locked pcsition by the coin-controlled mechanism and thereby holding the selector bar against movement until another coin is inserted. Each magazine 12, Figs. 4 and 5, for articles 13, is provided with an ejector 85 of U-shape having an operating knob 82. Spring-controlled locking catches 72 co-operate with the ejectors, so that the last ejector pushed in to deliver an article, is prevented from moving outwards under the action of an associated spring 78. After the insertion of a coin and actuation of an outside lever, a shifting bar 65 is moved against the action of a spring 68 and pins 69 thereon engage upstanding portions 71 of the catches 72, to release these and allow the ejector to be moved outwards, all the ejectors being now in their outward position. Each ejector is provided with a, lip 91 which, by the outward movement, is disengaged from a corresponding notch in a laterally movable selector bar 93, the notches in the bar 93 being so arranged that only one notch can register with an ejector at a time. The bar 93 is moved by a knob 102 to bring a notch opposite the ejector of the selected magazine, the ejectors of the other magazines being thereby blocked and a pointer .on the knob 102 indicating the selected magazine. When the selected ejector is pushed in, it pushes out the bottom article past a retaining spring 107 to a delivery tray 109. This ejector being now held by its catch 72, its lip 91 locks the selector-bar 93. The operation of the outside handle, after prepayment, rocks a shaft 46, Fig. 1, carry ing an arm 47 provided with a pawl 53. On the return oi the shaft 46 by a spring, the pawl 53 engages a lever 57 which rocks a lever 61. A roller 64 on the lever 61 engages the bevelled end of the shifting-bar 65 and moves it to release the ejector-retaining catches 72. Coin action, with stationary coin forming abutment.-The outside handle operates a lever 17 and a member 43 rigid therewith, the member 43 carrying a pawl 44 which engages an arm 45 on the shaft 46 to rock this. In the absence of a coin, a lug 34 on the lever 17 engages a shoulder 25 on a lever 24 connected to a lever 28 which carries a pin 31 moving into the coin shoot 16. A coin prevents movement of the pin 31 and the lever 24, thereby allowing the lever 17 to pass. Coin-slit closing-devices.-Pivoted fingers 112 are engaged by the articles 13 in the magazines 12 and hold a coin-slit closing-device in its open position until the magazines are empty.
