Abstract: 8882. Heide, H. C., [American Mechanical Cashier Co.]. April 20. Calculating-apparatus ; receipts, checking and recording.-Machines for computing, indicating, recording, or otherwise facilitating money transactions, or other operations involving weights &c., but, more particularly, subtracting-machines, such as change indicating or giving machines, are provided, in combination with the number-indicating means, with means for giving results, and with connecting means between these other means and operative with the significant figures of the number-indicating means in a lower numerical place to present on the result-giving means in a higher place the value of the higher place less one of its units. A changecomputing machine for American money, or mechanical cashier, with an automatic till from which the change is taken, is shown in Fig. 2, and is shown schematically in Fig. 35. Fig. 4 shows the machine in sectional plan. The amount-paid or deposit keys 2 are arranged across the front of the machine, while the purchase or price keys are arranged in four groups 3, 4, 5, 6, three nines, and a single key, in front of the deposit keys, as shown in Fig. 35. The result is given by the wheels 7, loosely journalled on the shaft 8, and corresponding to the deposit keys. The means connecting the number-indicating and the result-giving means consists of a system of independently-movable members 3<a>, 4<a>, 5<a>, 6<a>, comprising various sets of connections corresponding to the various numerical places of the machine. The members include also various auxiliary sets of connections corresponding to certain sub-denominations. The sets of connections corresponding to the respective numerical places may be composed of separate and independent elements, or each set may be composed in whole, or in part, of the same members, which form another set or sets. Some of the auxiliary sets are composed of independent elements, and some are composed in whole, or in part, of elements forming parts of other sets. Actuation of the deposit keys operates the three sets of locking-devices located on the shafts 91, 102, 131 above the connecting-bars, and also sets the sign cylinder 180 to show 'amount received' and the cylinders 7 to indicate that amount. The actuation of the deposit keys also releases the locking-bars 89 so that the purchase keys can be actuated, as also the purchase-price indicator and recorder actuating-bars 239. Actuation of the purchase keys sets the two systems of locking- devices operated by them, the devices being, normally, held in their locking-positions by the locking of the actuated keys, and releases the main shaft 23 of the machine. The shaft 23 is rotated through one revolution by a crank handle, and its motion is communicated to the shaft 21. The first part of the revolution of the shafts 23, 21 permits the connecting - bars which have not been locked to move forward so as to set the corresponding dogs 171. The cams 174 then act to lift the frame 165 and release certain detents 153 and all the detents 177. This permits all the cylinders 7 operated to return to their normal positions, and renders operative the cylinders 7 corresponding to the actuated detents 153 to indicate the result. At the same time, the cash drawer 195 is released, and the sign cylinder presents the sign 'amount of change.' The bars 239 are also moved forward to actuate the indicator cylinders 233 and the recorder cylinders 245. During the latter part of the revolution of the shafts 23, 21, the connecting- bars and the recording-bars are returned to their normal positions by the action of cams 20, the locking-bars 89 for the purchase keys are moved and release the keys by cams, and other parts are returned to their normal or inoperative positions. The auxiliary locking-devices for the keys 4, 5, 6 are a series of rocking plates, similar to the oscillating transverse rockers, shown in Fig. 4, of the setcontrolling locking-devices located beneath the connecting-bars. Suitable means retain the deposit keys in their actuated position. When the machine is used for paying out money, the cylinder 180 is set to 'paid out' by the thumb-wheel 215, Fig. 13, this operation serving, through the action of the links 226, to release the paid-out sets of connections, controlled by the shafts 205, 206, and to lock all other sets of connections, and to release the purchase-key locking-bars 89. The movement of the frame 255, by the operation of the paid-out devices, is not sufficient to release the recorder bars 239. The money to be paid out is indicated on the purchase keys by their depression, and the shaft 23 is afterwards rotated. The recording- cylinders 245 continuously add up the amounts of the purchase prices indicated on the machine. In the modified machine, shown in part in Figs. 18 and 19, receptacles 270 are provided, in which money received is deposited, and from which amounts, constituting the change, are delivered automatically by the ejecting-fingers 275. Excess money is discharged into the drawer 278 by the ejectors 280. The mechanical parts in the automatic change-giving apparatus are the same as those in the non-automatic machine, except in those parts relating to the cash drawer. Numerous arrangements of the various sets of connecting- bars are adopted in order to effect the subtraction of various sums of money from other and particular sums set by the deposit keys in different monetary systems. The improvements are applicable to machines working with English money.
