Abstract: 13,236. Chiger, S. June 29, 1910. Money-delivering apparatus. - In a coin-counting and change-giving apparatus wherein the ejecting-slides are actuated by compressed air and controlled by drums provided with shoulders, adjusting-parts connected to the drums are provided with scales each associated with a setting-part, which latter parts are moved to indicate the sum of the amount tendered, after which the adjusting-parts are moved so that the figures on their scales corresponding to the purchase amount are placed opposite the setting-parts, the drums being thereby set in position to deliver the amount of the difference as change. The machine is provided with thirteen coin-slots made up of a set 2 for copper coins, a set 2a for nickel coins, a set 2b for silver coins, a set 2<c> for gold coins, and a slot 2<c> for notes &c., which are placed in packets. Each slot leads to a channel 3 in which works a roller push 4 to push the coins past an abutment 11 to actuate a counting-lever 10. into two or more coin-tubes 5, 6. The lever 10 actuates a ratchet-wheel 13 attached to a counting-train. The ejecting-slides 14 are attached to pistons 17 in cylinders connected through taps 19 to atmosphere or to compressed-air pipes 20, the taps being operated by rods 52 and returned by springs. Each slide carries a tappet 28 to actuate, on advance, a lever 29, which through links 30, 31 releases a pawl 32 to allow the ratchetwheel 13 to spring back through one step to show the number of coins contained through windows 13<1>. Attached to the wheel 13 is a pinion 33 with the same number of teeth as there are slides for each tube 5. The pinion 33 engages a sector 34 with the same number of teeth, and advances it to the right, when the first coins enter. An intermediate wheel may be provided. When the pinion returns to its first position, when the tube 5 is empty, the sector 34 is returned and prevents operation of the ejectors 14. The storage tubes 6, from which coins are not ejected but removed by pulling out a slide 14<1>, have a normally raised flap 9 which, when lowered, throws out a clutch between the wheels 13, 33. The tubes 20 communicate with a compressed-air reservoir 26 through taps 21 on a common spindle provided with a handle 23. Fig. 1, working in a slot in the casing. For controlling the ejectors, four drums 55, 55<1>, 61, 62, Fig. 2, are provided in German coinage for units and tens of pfennigs, units and tens of marks. The drums are mounted on concentric shafts 58, 63, 64, 65 carrying end disks 67, 68, 69, 70, and between the shafts are shafts 114, 115, 116 which, together with hollow shafts 117, 118, carry indicators 109 ... 113, and are connected to cog-wheels 119 engaging adding and indicating mechanism. A further hollow shaft 71 provided with a disk 72 carries a cog-wheel 73 acting on the mechanism for delivering paper money. A ratchetwheel 66 is fitted to each drum, which has a number of rows of projections corresponding to the number of ratchet teeth. Intermediate rows are also provided for spare coin tubes. The wheels 66 are engaged by pawls 74, 75, 76, the pawls 74 being carried on levers 59 mounted loose in the shaft 58, and being connected to the levers 59 by links 78, 80 the joint of which carries a roller 81 engaged by a fork 82 attached to an arm 84 of the lever 59. The arm 84 has a projection 85 against which is spring-pressed a roller 88 on a slide 87, the back end of which engages a guide 126 having notches 127, 128, and the front end having a nose 124 capable of engaging a lever frame 120 reaching across the machine. The frame 120 is pivoted on the shaft 55 and has projecting pieces 57, and a handle working in a slot 121, Fig. 1, *in the frame, and connected to the rod 7 of the pushers 4. The pawls 75, 76 are mounted on a shaft 92, the former having a tappet 94 and a projecting piece 93 connected to an arm 99, with the lower end of which a fork 100, carrying a cam 102, engages, and the latter pawl having a pin 96. The toothed sectors 34, Fig. 2, are connected to wedge-pieces 39 working between rollers 40, 42, the latter being carried on a rod 41 pivoted on a rod 43 the other end of which carries an arm 104 in a slotted support 106, the end of which lies under a projection 103 of the arm 93. The lower end of the rod 41 has a lug 46 projecting under jointed pieces 47, 51 carried by a shaft 48 on crank-arms 49 held by springs 60. In working, the coins tendered are inserted, and the indicators 109... 113 moved along the numbered disks until opposite the figures corresponding to the amount. The disks are then turned until the figures corresponding to the purchase amount lie opposite the indicators. The drums are then in position to cause the ejection of the difference as change. The lever 120 is then turned, the pushers 4 being simultaneously actuated. The first movement swings the levers 57 out of the path of cams 56 to allow the springs 60 to swing the levers 51 into the path of the projections 64. The movement of the lever 120 is communicated to the levers 59 by the noses 124 and the pawl 74 forces the drum round to engage a projection 54 over a lever 51 to force down a rod 52 so that on the subsequent opening of the taps 21 the change will be ejected. If any coin-tube be empty, the corresponding sector 34, having been returned to the left, raises its wedge 39 to swing over the lever 41 under the lever 51 to prevent operation of the rod 52. Turning of the drum then depresses the lever 41 and raises the lever 104, and consequently the pawl 75. The pawl 74 is also disengaged bv the outward pressure of the cam 102 on the roller 81, so that the drum is turned back by its spring until held by the pawl 76, in which position a row .of intermediate projections are carried above the levers 51. The projections interact with levers 51 corresponding to the spare coin-tubes. For instance, on the shaft of the lever 43 of the five-mark tube are hung levers corresponding to spare two- and three-mark tubes. These tubes have counting-trains complete, but their wedges 39 have greater slope and their supports 106 longer slots. Consequently, when a five-mark tube is empty, its drum springs back as described, and further movement of the lever 120 causes the engagement of the secondary projections with the rods 52 of the reserve three- and two-mark tubes. If either of these is empty, its wedge rises and moves over the lever 41 to stop the movement. At the same time, the pawls 74, 75 are thrown out by the rising of the lever 104, which is now of sufficient extent to cause the throwing-out of the pawl 76 by the engagement of its pin 96. The drum is thus free to return to its normal position, and the tubes must be filled before change can be ejected. The pawl 75 in its forward movement passes the double fork 95 on the lever 120, being held on the right-hand fork if the first tube is empty, and on the left if both the additional tubes fail. On returning, it allows the lever 120 to carry back the levers 59 by raising the pawl 75 to press out the projection 85 against the roller 88 to prevent the retraction of the slide 87 and the disengagement of the nose 124, as the notches 127, 128 are passed. The ejected coins fall into a pivoted trough 130 divided into compartments by partitions rising through slots in its base. The trough can tip on its pivots so that the partitions leave the trough free to allow the coins to slide into a bowl.
