Title: Improvements in coin collectors for automatic vending machines
IPC: G07F1/04
Filed: 1934-07-06
Abstract: 423,483. Coin - freed apparatus. HEILAND, A., and DOMCKE, E., 101, Bulowstrasse, Berlin. July 6, 1934, No. 19915. [Class 27] Coin action, weight and multiplecoin.-In coin-collecting mechanism for vending machines, the coins inserted in a slot 6, Fig. 1, roll down a shoot 7 and drop in succession into shoots 12-12<111>, the last coin of the number required for prepayment for an article passing to a shoot 12<iv> where it trips or actuates mechanism to release the previously inserted coins of the series and to effect goods delivery. Each of the shoots 12-12<111> has pivoted at 3 outside one wall 1<1>, Fig. 3, thereof a shutter 2 provided with a tongue 4, which enters the shoot through a slot 5, when a coin has dropped into the shoot and moved aside a tail-piece 15 on the shutter, the coin coming to rest on a support 13 carried by a rockable rod 14. The tongue 4 provides a platform over which the next coin rolls to the next shoot of the series, each shutter in its open position carrying a stop 9 which prevents the coin from jumping over the open mouth of the shoot. The last coin passing down the shoot 12<iv> displaces a bar 17 projecting from the rod 14 and rocks this rod to release the coins on the supports 13. The rocking of the rod 14 actuates a device, (not shown), to allow or effect delivery of an article. When the coins are released, the shutters return by gravity to their open position. One or more of the shutters may be closed by levers 8, which are under the control of an official, so that the mechanism may be set for collecting payments of different amounts.

Abstract: 293,770. Menz, W., and Hielscher, A. July 11, 1927, [Convention date]. Road-traffic signals on vehicles. - Signals for indicating a proposed turn to the right or left of a motor-vehicle are actuated by handle 17, and are subsequently restored to neutral position by a cam-shaped member 20 fixed to the steering-wheel 19. Each handle 17 actuates its own signal by lifting a sliding element 5 to the posttion shown, thereby operating a Bowden cable 14 against the action of a spring 3. In this position the apparatus is locked by a projection 7 on a spring-pressed pivoted member S engaging the top edge of the fixed casing 1. When the steering-wheel 19 is being brought back to the '' straight ahead " position, the outer edge of the member 20 engages a spring-pressed bolt 9 and releases the locking-element 8, so that the spring 3 restores the slide 5 to the initial position. Electric lamps for the signals may be lighted, or electric actuation thereof may be effected, by contacts moving with the slide 5 and co-operating with contacts on the casing 1.

Abstract: 1,138,304. Road traffic signals. BULLFINCH (GAS EQUIPMENT) Ltd., and R. K. LYNES. 4 May, 1967 [7 May, 1966], No. 20324/66. Heading G4Q. A control system for gas illuminated traffic signals 69, 70, 71 includes means 60 for providing pulsating gas pressure and a timer 7-10 actuated by the pulsating gas pressure. Each impulse of gas pressure steps a ratchet member 27 round one notch, and a variable ratio transmission drive 9, 34 couples this to a cam 47 which actuates angularly adjustable switches 51, 52, 55, 56. A pin 58 on disc 34 co-operates with arms 41 to actuate further switches 46. The gas is also fed via solenoid operated valves 65, 66, 67, 68 to the traffic signals. As described, Fig. 8, two sets of signals at opposite ends of a section of road to be controlled are connected to the timer via change-over contacts on switch 46. Assuming both signals show red, then with the switch 46 as shown, rotation of the timer will switch the left hand signal through its phase sequence R, RA, G, A, R as switches 51, 52, 55, 56 are sequentially operated to complete the circuit to solenoids 116 which operate the valves. At the end of the sequence, pin 58 operates switches 46 to connect the right hand signal to the timer while the left hand signal remains at red. The next rotation of the timer thus switches the right hand signal through its phase sequence.

Title: Improvements in or relating to methods and machines for making grids for electron discharge tubes
Inventor: KELLY EARLE SAMUEL
IPC: H01J19/00
Filed: 1962-05-30
Abstract: 933,180. Making grids for electron-discharge tubes. PHILIPS ELECTRICAL INDUSTRIES Ltd. May 30, 1962, No. 20853/62. Addition to 884,472. Classes 83 (2) and 83 (4). A modification of a method of making grids for electron discharge tubes as disclosed in the parent Specification, wherein instead of gripping and stretching the backbones with the pair of stretching jaws after the pair of feeding jaws has been brought to a standstill, a wound portion of the backbones between the two pairs of jaws is stretched during the movement of the backbones and the feeding jaws by gripping the backbones with the pair of stretching jaws and moving the stretching jaws at a faster rate than the feeding jaws, after which the feeding and stretching jaws release their grip of the backbones and return to their starting positions. The modification to the apparatus comprises a pivot 18 fixed on the slide 10 upon which is mounted a lever 16, one end of which is arranged to abut against a fixed stop 13 and the other to carry a roller 17 which bears against a bracket 20 secured to the slide 14. Movement of the slide 10 to the left causes the end of the lever 16 to abut the stop 13 and rotate in an anticlockwise direction such that the roller 17 contacts the bracket and moves the slide 14. The jaws 15 close and a wound portion of the backbones 3 between them and jaws 11 is stretched due to the faster rate of travel of the slide 14 relative to the slide 10. An alternative lever arrangement comprises a block 25 to be fitted to the slide 10 which comprises an arm 24 pivoted about a shaft 26 and abutting a stop assembly 21 to be fitted to a stationary part of the machine. The other end of the arm 24 carries a shaft 27, a pivoted coupling 28 to which is fitted a pivoted hollow member 30 having an air outlet 31 and a small bore 36. A bracket 32 which is to be secured to the slide 14 carries an internally threaded sleeve 33 through which a rod 34 is screwed so that its end protrudes into and abuts against the face 35 of the member 30. The distance between the slides 10 and 14 is adjusted by varying the depth of engagement of the rod 34 within the sleeve 30. An adjusting screw 24 varies the distance between the shafts 26, 27 and hence the relative speeds of the slides 10, 14. In operation as the slide 10 moves to the left the arm 24 pivots in an anti-clockwise direction about shaft 26 and the rod 28 and member 30 push the rod 34 causing the bracket 32 and hence the slide 10 to move to the left so that a wound portion of the backbones between the two pairs of jaws is stretched. The feeding jaws subsequently open and the slide 10 together with the block 25 and member 30 return to their starting positions. The bore 36 restricts the release of air which acts as a damping medium, from the member 30 during the return stroke of the rod 34.
