Abstract: 212,589. Chick, T. W., and Rapid Change Syndicate, Ltd. Sept. 16, 1922. Money delivering apparatus.-Relates to coin delivery machines of the key-board. controlled type. In order to avoid excessive resistance to the operation of the ejecting mechanism due to the weight of the stored coins, means are provided for separating from each group a portion from which ejection can be effected. The device comprises a casing 1 having finger keys 2 to determine the total value of the coins to be delivered, and a lever 3 which is operated to eject the coins bv the ejectors 4. A casing 5 contains chain conveyers, each comprising two endless chains 11 passing round a sprocket wheel 12 and wheels 13, 13<1>, the chains having transverse partitions 15 forming with a stationary table 16 compartments to receive and retain coins 17 on edge. Each conveyer is independent and has a coin receiver 18 allotted to it. Each sprocket wheel 12 is formed with a ratchet wheel 20 driven by a pawl 21 which is carried on a bar 22. The bar is moved by the operation of the lever 3, a mask 23 determining the effect of each pawl on its ratchet wheel according to the space left vacant in the receiver for coins. The mask 23 is mounted on a lever 24 pivoted to a toothed segment 26 which is carried' by a lever 27 pivoted on a sleeve 28 of a squared shaft 29. A detent 3 having an arm 53 which is raised by a bar 54 on the operation of the lever 3, engages the teeth of the segment 26. A feeler 33 touching the coins in the receiver 18 is pivoted to a lever 35 freely mounted on the sleeve 28, and the levers 27,35 have bosses with interengaging jaws which allow limited movement between the levers. A lever 38 on the squared shaft 29 has a lug 39 which lifts the lever 35 and the feeler 33 each time the shaft 29 is rotated on each delivery operation of the machine. The coins in the conveyer fall down a shoot 48 to the receiver 18, the shoot 48 being normally closed by a shutter 69 provided with teeth 70 and an opening 72. The shutter is opened by a lever 73 which is pivoted to a rod 76 moved back by the pin 77 of a crank 78 mounted on the shaft 29. The delivery lever 3, Fig. 3, operates a cam plate 63 having cams 65 for operating a bell-crank lever 67 on the square shaft 29, and also cams 60 which operate the pawls 21, Fig. 1, and release the detent 30. In the example shown, two intermittent feeding motions are given on each delivery operation of the machine. At the beginning of the movement of the lever 3 the feelers 33 are raised and held raised until the pawls 21 rotate the ratchet wheels 20 to the extent allowed by the masks 23 previously set by the feelers 33. If coins are required in any receiver 18 the conveyer will move forward and coins will fall over the shoot 48 into the receiver 18. Towards the end of the movement of the lever 3, the detent 30 is raised 'by the bar 54 to release the segment 26 and allow the lever 27 to rise by the action of a spring to the top position determined by the engagement of the bosses of the levers 27, 35, so raising the mask 23 to the top position. The mask levers 24, the segments 26, the levers 27 and the feelers 33 then fall together under the influence of a spring 47 until the feelers 33 strike the coins in the receivers 18, the detents 30 slipping on the segments 26 which have been released by the bar 54. The masks are thereby set for the next operation. Should a coin jam in the receiver, the casing 5 oan be raised and a wire loop 82 pulled to tilt the receiver and eject the coin. If the receiver becomes empty, a projection 84 on the receiver engages a lug 85 on a lever 44 and locks the delivery lever 3.
