Title: Improvements in or relating to motor vehicle quarter-light assemblies
IPC: B60J1/04
Filed: 1958-01-16
Abstract: 877,692. Vehicle windows. BAYERISCHE MOTOREN WERKE A. G. Jan. 16, 1958 [Jan. 16, 1957], No. 1596/58. Class 137 A motor vehicle quarter-light is actuated by a device comprising a member resiliently urging the quarter-light into the closed position and movable into the open position by the difference in pressure between the inside and outside of the vehicle. As shown, a quarter-light 1 has secured to it a bracket 7 the free end of which is slotted and is pivotally attached to one arm 5b of a toggle 5b, 5a, the free end of the arm 5a being attached to a fixed bracket 6. A second toggle, 8, 9 has one end pivoted to a pin on the bracket 7 and the other pivoted to the arm 5b, a spring 10 urging the arms into the closed position. When, due to the movement of the vehicle, the pressure outside the vehicle is reduced, the pressure inside overcomes the resistance of the spring 10 and the quarter-light opens to an extent depending on the difference in pressure. A hook 12 may lock the device in the closed position and the toggle- 5a, 5b, may be used to open the quarterlight manually. In a modification, Fig. 3 (not shown), the spring 10 is replaced by a spiral spring, adjustable in tension, the second toggle is housed within the arm 5b, and the device may be locked in the closed position by moving the second toggle beyond the dead centre position.

Title: Machine for automatic selling
IPC: G07F11/16
Filed: 1937-02-18
Abstract: 492,366. Coin - freed apparatus. STANBRIDGE, H. Feb. 18, 1937, No. 1676/36. [Class 27] Testing coins.-The upper face of a coin inserted through a slot a<2> engages a finger bl of a pivoted lever B carrying a pair of pins b2 normally locking a pair of fingers c, pivoted at c<1> on either side of the slot, and blocking the coin passage' by their tips c<3>. A coin of sufficient thickness raises the lever B and pins b<2> sufficiently to free the fingers c which are thrust aside by the coin. The rim of the coin on insertion displaces a pair of fingers E turning with levers F whose bevelled rear ends depress a bar G connected by a pin g<1> with a lever D having a downturned end d<1> serving to block the entrance of under-diameter coins. If the coin is of full diameter, the end dl of the lever D is raised sufficiently to clear the coin. Coin action, weight and multiple coin.-The fingers c close, under spring action, behind an accepted coin and draw it over an aperture H in a fixed plate through which it falls onto a pivoted spring-actuated flap. When two coins have been inserted, their weight tilts the flap and they fall edgewise into a shoot L. The base of the shoot is formed by a projection m<1> on a sliding wall M which is normally held in a raised position by a spring contact blade beneath. The weight of the coins depresses the shoot wall M and base m<1> to close the contact and energize an electromagnet operating the delivery mechanism. In its lower position, the wall M clears an aperture L<3> in the opposite fixed wall of the shoot so that it immediately rocks inwardly to release the coins, the contact then raising it to its original position and breaking the circuit. Articles stored in piles.-The articles are stored in a vertical pile over a delivery drawer W which is connected by a rack V, gearing T, and a rack S with the armature of the electromagnet. The open front of the drawer is covered by a pivoted flap X locked by engagement of a pin x<1> with a spring-loaded catch Y. The momentary energization of the electromagnet causes the drawer to be thrust out, the catch Y being lowered out of locking engagement with the flap X as a tooth y<1> passes out of an aperture w<2> in the drawer. The drawer is held open against the 'action of a return spring by engagement of a notch w<1> therein with the tooth y<1> of the catch. When the article is removed from the drawer, the flap X falls and its pin x<1> depresses the catch to release the drawer which consequently closes.

Title: Improvements relating to automatic fluid-operated regulators
IPC: G05D16/18
Filed: 1934-01-17
Abstract: 431,710. Fluid-operated regulators. GORDON & CO., Ltd., J., and SCHIPPERS, J. F., Regent House, Kingsway, London. Jan. 17, 1934, No. 1712. [Class 135] Means are provided for compensating the spring - loading of a weigh - beam which beam is influenced by fluid - pressure and controls a servomotor actuating a main regulating valve or the like, the valve or the like having a determined position for every position of the weigh beam. The compensation may be such as to bring the spring - loading to a substantially constant value whenever the weigh-beam is stationary in its range, producing a substantially con - stant value of the controlled condition, or the spring-loading may be over- or under - compensated to give a varying range of the controlled condition. Where the servomotor is operated by compressed air, means may be provided to retard the opening of its pilot valve. In the Figure, the weigh-beam 14 fulcrummed at 15 is acted on at 16 by a bellows, &c., housed in a chamber 17 and subject to the fluidpressure to be controlled by the main valve. In rising, the beam 14 by a rod 13 turns a lever 9 about a floating pivot 10 to depress a pilot valve 5 admitting compressed air led in at 6 to the lower end of the servomotor 4 raising a cross-head 2 and closing the main valve attached by a ball and socket joint 1. The floating pivot 10 is carried on an arm 11 pivoted at 12 and is simultaneously raised, by a cam 21 moving with the cross-head 2 and acting on a roller 22, to restore the pilot valve 5 to its raised position. The extension of the loading spring 18 acting on the beam at 19 is compensated by a cam 35, also carried by the cross-head and acting on a roller 34 which by a bell-crank pivoted at 32 and a link 30 controls the movement of a plate 27 pivoted at 28 and supporting the lower end of the spring. The amount of compensation of the spring extension may be varied by adjusting the cam 35. To limit the rate of opening of the pilot valve while allowing movement for small changes in pressure, a screw 37, mounted on an arm 38 pivoted to the arm 31, and guided at 39 for vertical movement, projects normally centrally into a slot in the end of the weigh-beam; the weigh-beam moves smoothly in contact with the screw 37 once the latter has contacted with the edge of the slot. The cam 35 may be omitted, the control of the spring compensating lever and the screw 37 being effected by the cam 21 through levers.
