19,137. Kent, G. P. Sept. 11. Money-delivering apparatus; coins, separating.- Relates to coin-separating and change-distributing mechanism of the class designed for application to a key-operated cash register, and consists of a coin-separating device by which the coins tendered are separated and stored, a change-determining barrel, mechanism operated by the operation of the coin-separating device for setting the barrel in position according to the amount of the coin tendered, and mechanism associated with the barrel and with the cash register whereby the independent parts of the barrel are placed in position to ensure the ejectment of the correct change. The apparatus described is arranged to receive silver coins up to half-a-crown in value. Fig. 1 is a front elevation o:E the upper part of the apparatus, Fig. 2 a similar elevation of the lower part, Fig. 5 an end view of the apparatus of Fig. 2, Fig. 6 a side view of the coin-separating apparatus, and Figs. 15, 18, and 19 show views of a modified form of coin-separating and indicating- drum actuating-means. The machine is provided with two keys 2, 3, the former of which is depressed when no change is required, and the latter when change is necessary. The key 2 is at the extremity of an inwardly extending spring-held rod 5 having a projection 8, which, when the key is depressed, operates against a depending member 9 of a lever 10 pivoted, on the spindle 11 of an indicating-drum 12. The lever 10 carries a "no " change" plate 13, which, when the lever is operated, shows through a display orifice in the casing. On an extension 15 is mounted a lever 16 similar to the lever 10, and this lever is connected by a bar 17 with a shutter 4, which normally closes the slot 1 in which silver coins are placed. The pressure of the key 2 therefore allows a coin to be inserted, and the coin then falls on to a laterally sliding plate 18, which closes the lower end of the slot. To prevent the key from returning directly it is pushed in, a pivoted gravity pawl is provided on the frame, which engages a stop on the rod 5. The pawl is released, when the change key 3 is depressed, by the rocking of the shaft 173 and connexions therefrom to the heel of the pawl. A box 20 carried by the frame 19 is adapted to be slid forwards by the handle 48 and is provided with four guide slots 22, one for each denomination of silver coin. Pivoted upon a spindle 23 are four cam-plates 24 provided with flanges 25, each flange lying level with or slightly below one of the slots, and with edges 26 projecting different distances through the bottom of the box. These cam edges operate on a lever 29, which carries a rack 30 gearing with a pinion 31 on a shaft 32, which also carries two pinions 36 gearing with racks on the support for the coin-tubes 39. Pivoted in the frame is also a lever 44, which carries at its upper end a horizontally supported bar 46. When the handle 48 is pulled forwards the pin 49 clears the projection 50 and allows the rods 44, 46 to fall, and a pin projecting from the latter rod enters the coin slot and rests on the coin therein. The further motion of the box causes the slide 46 to enter one of the slots 22 and lock downwards one of the cams 24, the particular slot entered depending on the diameter of the inserted coin. The particular cam held down depresses the lever 29 and gives a corresponding movement to the pinions 36, thereby causing the rack 37 to move the corresponding coin-tube under the slot 1. At the end of the movement, a pin 53 pushes aside the plate 18 to open the slot to allow the coin to fall into the tube 39, where it is held on the forked end 57 of a stop 55 the other end of which works in a cam-slot in the rack 37. The operating handle 48 is then released, and the box 20 and the coin-tubes 39 return, and at the end of the movement the lever 55 is moved out by the slot to allow the coin to fall into the corresponding lower coin-tube 58, over which the tube 39 normally rests. Carried on the piece 65 which bears the rack 30 is another rack 69 gearing with a pinion 70 on a shaft 71, which also carries a pinion gearing with another pinion 74 in gear with a rack 75. Beneath the rack 75 is a rack 77, gearing with a pinion 78 on the shaft 11 of the drum 12, which indicates the amount of the coin tendered when the change key 3 is depressed. The key has an arm 79 attached, the upper end 80 of which travels parallel to the racks 75, 77, the former of which carries a bell-crank bracket 81, having a spring- controlled pin 82 on one arm. When the change key is depressed, this bracket is turned, and the pin enters a notch in the rack 75 above one of a series of holes in the rack 77. When the coin has been inserted and the box 20 is pulled forwards, a cam extension thereon contacts with the end 87 of a pivoted plate 88 and depresses the pin 82 into the hole in the rack 77, thereby locking the racks together and causing the motion of the rack 69 to be communicated to the drum 12 to display through the aperture in the casing, the amount of the coin tendered, the amount of the movement and therefore the indication given depending on the amount of motion communicated to the rod 29 by the locked cam-plate 24. If payment is made with more than one coin, two separate actuations are necessary, and the effect on the drum is cumulative ; the pin 82 at the second actuation entering another of the series of holes, the advancement through each hole adding sixpence to the amount indicated. A flexible connexion 91 leads from a pulley on the drum spindle, over a guide pulley 92, and is connected to the segmental member 94 of a lever 95, Fig. 5, pivoted on the spindle 96. The segmental member 94 is connected to a silver-change controller 98, which consists of a plate movable in both directions, and provided with stops 100 in the top edge, over the top one of which the extension 101 of the toothed segment 102 depends, which segment gears with a pinion 104 attached to a barrel 105 mounted loose on the laterally slidable spindle 179. The barrels 105, 106, 107 drilled with holes 108, 109 control the amount of silver, penny, and halfpenny change respectively, and in front are mounted slidable plungers 111 ... 119, which control the delivery of two shillings, one shilling, sixpence, one to five pennies, and a halfpenny, respectively, when pushed forwards by the barrels. The plungers are normally in line with holes in the barrels. When the coin-tendered drum 12 is operated, the connexion 91 causes the silver barrel to turn so that plungers corresponding to the amount tendered will be out of line with the holes and will be pushed forwards when the barrels are operated. The copper barrels will not be affected by this operation. In order that the correct change may be delivered, equivalent to the difference between the purchase and the coin tendered, the silver keys of a cash register are connected to cams 125 mounted in a frame 124, which cams slide forwards when the keys are depressed and depress through different distances the lever 130, with a pin 129 on which the depending surfaces contact. The lever 130 carries a toothed segment which actuates a rack 123 through wheels 132, 134, and this rack communicates lateral motion to the silver-change controller 98 and places another step beneath the projection 101 ; thus allowing the segment 102 to drop and so return the silver barrel through an amount corresponding to the amount of the purchase, so that plungers controlling the correct amount of change only are in position to be pushed forwards. The movement of the controller 98 through each space of one step deducts sixpence from the change. The pence barrels are, however, not set for the full amount and returned, but are set at once to the amount of change necessary. The pence keys of the cash register are connected to a series of similar cams 143, which operate similarly a pence controller 137 having steps 138, on the top one of which normally rests the projection 149 of a toothed quadrant 150, which causes, when the projection is allowed to drop to another step, the movement of the pence barrel to a corresponding amount. The cam-operated lever 140 is also connected to a transfer-cam 153 similar to the others and placed over the silver cams, which has two steps on its underside, of which the first causes the movement of the silver cams one step to deduct sixpence from the silver change when pence keys up to sixpence in value are operated, and the second of which causes a further deduction of sixpence when pence keys up to elevenpence are operated. A similar transfer-cam 161, with one step only, operates when the halfpenny key is depressed to allow the quadrant 166 to fall and turn the halfpenny barrel. After the barrels have been set in the correct position, the change is ejected from the shoots 58 by pulling the handle 168, which together with the arms 149, 166 are unlocked by the depression of the change key 3, which carries on its underside a bevelled depending catch which depresses a rod 171 and causes a lever 172 to be tripped so that the lever 175 is disengaged from the spring catch 176 and the locking- levers are disengaged from the notches 189. A second catch on the change-key rod engages the rod 171 and locks the key in its depressed position. As the ejecting-lever 168 is pulled forwards to press the barrel spindle along the slot 186, the catch 176 operates against the catch end 175, thereby further depressing the rod 171 and releasing the change key 3. The barrels are locked in position during their forward movement by pivoted catches 188 which engage racks 191 on the segment sides during the movement. The forward movement of the barrels presses forwards the change plungers selected, the others passing through the holes, and the bevelled front ends of the plungers pass through openings 198 in laterally-slidable spring controlled plates 192 ... 196 and move them over
