Abstract: 323,545. Castell, J. H. Oct. 5, 1928. Delivery of gramophone records; storage. -- Records in envelopes 3 are supported on a central bar 36 and are pressed towards the free end of the .bar by a spring 41, and the end record which is free of the bar is delivered through a slot by a lever 26, Fig. 4, when an external hand-lever 6, Fig. 3, is turned after the insertion of appropriate coins. As shown, supplies of different records are stored in separate chambers 1, and an external selector arm 17 set by the purchaser renders the appropriate delivery mechanism operative. The external operating and selecting levers. 6, 17 turn spindles 5, 8 running through the coin chamber 4 and all the storage chambers 1. Each delivery lever 26 is connected by a link 25 to a plate 7, Fig. 6, loose upon the spindle 5 but driven by a pawl 12 which is carried upon an arm 11 on the spindle and engages a tooth 13 on the plate 7. The selector mechanism moves one of the pawls 12 into operative position, as in Fig. 4, whilst the other pawls 12 are out of range of the tooth 13 as shown in Fig. 6. For this purpose, a pin, 16 on each pawl engages in a slot 15 formed in a plate 10. The plate 10 is slotted at 10<a> to slide over the spindles 5 and 8, this adjustment being effected by cams 9 on the selector spindle 8. The spindles 5, 8 are interlocked by the device shown in Fig. 8 comprising a slider 23 engaging recesses 20, 22 so that the spindle 5 can only be turned when the selector spindle 8 is in one of its set positions and the spindle 8 can only be turned when the operating spindle 5 is in its normal position. To exclude rain, the delivery slot is closed by a pivoted shutter 50, Fig. 9, kept in place by a spring 52. The hinged front of the record chambers is secured by a fastening 55 operated by a lever 57 within the coin chamber 4. " Empty notices," displaying.-A cross-bar 49, Fig. 4, in each chamber rests upon the records and falls when the last record is delivered so as to show an " empty '' notice 44 against a window 45. Coin action, mechanical-connection and multiple-coin. - A number of coins, eg. four of different size, are inserted in slots as at 31, Fig. 5. Each coin first turns a bell-crank lever 34 free from a locking shoulder 35 on a lever 28, which extends the whole width of the slots and is fast on the operating shaft 5. The levers 34 are held in the raised position by a spring 34<b> engaging a flat 34<d> until the lever 28 in returning engages the short arms 34e. After passing the levers 34, the coins rest upon the ends of corresponding levers 29 which are normally held in position by springs 33 to lock the lever 28 at the shoulder 28<a>. If the shaft 5 is now turned, the coins transmit the movement of the lever 28 to the levers 29 so that the shoulder 28<a> is not obstructed. The coins finally pass the ends of the levers 29 and fall into the till. Unless all the required coins are inserted the lever 28 remains locked at 35 and 28<a>. As claimed, the arrangement of the three levers 34, 28, 29 may be adopted for operation by a single coin, or in multiple-coin apparatus only one of the three levers may be repeated according to the number of coin slots. Empty machines, locking. - A cross-bar 60, Fig. 4, supported on the records and extending across all the chambers is conected with a lever 66, Fig. 5. so that when the machine is empty the lever 66 drops and locks the levers 34, preventing the insertion of a coin in any slot.
