Patent GB-827559-A (GB)
Title: Improvements in or relating to dispenser
Inventor: SALISBURY ELLSWORTH CRAWFORD
IPC: G07F5/18
Filed: 1957-08-12
Abstract: 827,559. Coin-freed vending apparatus. IDEAL DISPENSER CO. Aug. 12, 1957, No. 25368/57. Class 27 In a machine for vending several different types of articles, such as bottled beverages, from corresponding sets of inclined shelves 27 by withdrawal of a selected bottle past a coinreleased gate 36, 37 or 38 the gates are normally locked by separate solenoid-operated release mechanisms 32 and insertion of a coin renders all three release mechanisms operative to release the gates but the action of withdrawing a selected bottle moves the corresponding gate to operate switches that de-energize the solenoids for the other two gates and thus hold them locked. Each gate is mounted on a shaft 42 spring-loaded towards the closed position in which a pin 60 on the latch 50 engages a locking shoulder 59 on a cam 46 carried by the shaft. A coin inserted in a slot 15 operates a switch D-3 which energizes a locking solenoid 126 of a holding relay 89 and the relay centre contacts move down so that contacts 93, 94 energize a circuit leading to double-pole switches A-3, B-3 in each gate release mechanism and contacts 104, 105 energize a coin-release solenoid 110 so that the coin is arrested. Opening of the contacts 93, 95 de-energizes a coin-rejecting solenoid 98 so that further coins inserted during the operating cycle are rejected by an obstruction to a return shoot. Withdrawal of a selected bottle rotates the corresponding gate 36 and a lobe 65 on the cam 46 engages a lever 66 to operate the switches A-3, B-3, thus completing a circuit to the solenoid 54 for the gate 36 and interrupting the current to the other release solenoids. Operation of the solenoid 54 withdraws the latch pin 60 and the gate is allowed to rotate further so that the lobe 65 engages a lever 84 and operates a switch C-3, thus completing a circuit to the unlocking solenoid 90 of the holding relay 89. The centre contacts of the relay move up and the contacts 93, 95 energize the solenoid 98 to remove the obstruction from the coin path and the opening of contacts 104, 105 de-energizes the solenoid 110 to release the coin into a coin box. Full-stroke rotation of the gate after operation of the switches A-3, B-3 is ensured by a pawl 76. Articles are successively vended from the uppermost shelf of each set of shelves and progressing downwardly and the customer gains access to the shelves by opening a door 20 having a transparent panel 21. A coin totalizer and change-giving mechanism may be provided and, when vending articles of different prices, a separate return wire from each of the gate release mechanisms leads back to the coin-receiving device.

Filed: 1930-07-16
Abstract: 359,503. Moulding paving slabs by stationary-mould machines. GHEUDE, L., 1, Rue AbbÚ Cuypers, Brussels, LEDOUX, A., 10, Quai de Meuse, Jambes, and DETHIER, E., 2, Rue Florent Dethier, both in Namur, both in Belgium. July 16, 1930, No. 25535/31. Convention date, May 22, 1930. Divided on 358,982, [Group X]. [Class 87 (ii).] Iron-bound paving slabs are pressed by running the hooped aggregate to the press ram, and then raising the latter so that the hoop enters a mould frame during the first portion of the stroke and the aggregate is compressed against a top abutment for the remainder of the stroke, the pressed slab leaving the mould in its suspended position on the - return stroke. In the form shown, metallic hoops 2 filled with cement are placed on pallets 4 and carried to the press on a conveyer 33, where they are raised by the ram 2 into the suspended mould 5 and afterwards pressed against a fixed abutment 10. On the return stroke the pressed hooped slab follows the ram downward leaving the mould suspended to receive the next slab. If the slab sticks in the mould, the supporting latches 16 are released simultaneously by operation of a hand-lever and the mould lowered for a short distance on the ram. The abutment 10 is then lowered by hand-operated screw mechanism 24 and the ram re-raised to eject the slab. The moulded block is removed by the delivery conveyer 34. The iron binding is formed with grouting recesses and corresponding projections are fitted temporarily to them to prevent deformation during pressing.
