Abstract: 15,218. Janik, E. July 7. Receipts, checking and recording.-Changegiving cash registers have coin receptacles from which varying numbers of coins are delivered by ejectors adjusted in height by stepped discs, connected together i n groups for the different units of currency. Two sets of keys are provided for each group of discs and receptacles, corresponding to the amount paid in and to the purchase price respectively, and limiting, when depressed, the operative movements of two motive-power devices which drive the set of discs in opposite directions. The movement of the latter motive-power device is transmitted also to the indicating, counting, and printing mechanism. The motive-power devices are wound up, and the ejectors actuated, by turning a crank at each operation of the machine. An indicator is provided for each coin receptacle to show when it needs refilling. The register shown in the Figures is adapted for German coin currency. Fig. 1 is a. vertical section of the machine, Fig. 2 a detail view of the mechanism for returning to.zero the indicator which records the amount of the previous transaction, Fig. 4 a horizontal section; Fig.. 6 a perapective view of a group of stepped discs and motive-power devices, Fig. 8 a front view 'of the crank driving-arrangement, and Fig.10 a view of'the printing-mechanism. There are four groups of coin receptacles 8, 9, 10, 11 for pfennigs, tens of pfennigs, marks, and tens of marks, 8<a> being for one-pfennig pieces, 8<b> for two-pfennig pieces, 8<c> for five-pfennig pieces, and so on, there being for each receptacle a slide 6 and stepped discs 2<a>, 2<b>, 2<c>, &c. To each group there are two springs 14, 15, Fig. 1, acting by means of bands upon the hubs 18, 19 of toothed segments 33, 34, which are loosely carried by a shaft 20 and have fixed to them arms retained by spring bolts corresponding to the two sets of keys 12, 13. The arm and spring bolt corresponding to one set of keys 13 are shown at 22 and 26<a> respectively. When a key is depressed, a loose sector 27 corresponding to the set is pushed on one side by the wedge-shaped projections 28 on the sector, thereby raising a bolt 26<a> by means of the pin 31 or 31<a> fixed to it, and releasing the arm 21 or 22, which is afterwards retained by the end of the depressed key. The toothed sectors 33, 34 act upon toothed wheels 35, 36, Figs. 1 and 4, firmly connected with the shaft of the corresponding stepped discs, and thereby turn the shaft and discs forwards and backwards respectively. A spring arm 37, the nose of which takes into a notch in a disc 39 on the shaft, holds the discs in the zero position. The number of slides 6 for each coin receptacle is the largest number of coins of the class which may require to be ejected at once. Instead of having more than one slide, more than one coin receptacle may be provided for each class of coin. A slide 45 upon a lever 46 pivoted at 47 carries a pin 47<a> which enters the eyes 43 of the slides 6, and, if there is more than one slide, a loose arm 42 is provided, having a projection 42<a> taking into the eyes to retain the slides which are not to be moved. Each slide 45 has also a pin 48, which engages in a hole in a bar 49, sliding longitudiually, and having a rack 53 driven by a toothed sector 55 on a shaft 54, which is turned first forwards and then backwards when a crank outside the casing is turned. The lever 46 has a pin 56 which is pressed against the stepped disc at the proper time by means of a cam 57 on the shaft 54, a lever 58, 60, toothed sector 61, and cam 63 acting on a spring 61 fixed to the lever. A cam-disc on the shaft 54 allows the lever to rise only when the adju3tment is to take place. The ejected coins slide to rolling-paths 66, and thence to the payboard. The springs 14, 15 are wound up by straps 67, 68 fastened to the periphery of rings or hubs 69 turning loosely on a shaft 70 and fixed to toothed segments 71. These segments gear with the teeth 72 of a partly-toothed disc 73 on the shaft 54. At the commencement of the turning movement of the shaft, the springs are wound up, ths smooth part of the discs preventing the return of the toothed sectors As the locking-levers 21, 22 are already released by the keys, to avoid jerks the levers are geared by means of toothed sectors 74, 75, 76, 77 with arms 76<a>, 77<a> which press against cams 78, 79 on the shaft 54. The cams are so arranged as to release gradually first the lever corresponding to the keys 12 and then the lever 22 corresponding to the keys 13. The crank 80, Fig. 8, is fixed to a toothed wheel 82 and connected by a pin and slot 84, 85 to a ratchet-wheel 83. The wheel 82 gears with a wheel 97, of twice its diameter, fixed to a partly-toothed wheel 98, which in the course of a revolution imparts one revolution to a wheel 100 and then one revolution to a wheel 101, thereby driving the shaft 54, by means of the wheels 102, 103, 104, 105, 106, alternately in opposite directions. This double rotation of the crank is to take place after the two sets of keys are depressed. The apparatus is locked in the final position by an arm 93 which arrests a stop 96 on the wheel 97. This arm and a spring pawl 96<a> are carried independently on a pivot 87 fixed to an arm 88 pivoted at 89, and the arm 93 has a projection 92 between pins 94 on the arms 88. In order to release the crank, it is turned backwards (to the left), and the ratchet-wheel acts upon the pawl 96<a> and carries back the arms 88, 93. To release the keys, a cam 107 on the shaft 54 strikes the jointed end of a lever 108, which yields in the forward motion of the shaft, but in the backward motion forces back the locking-sectors 27. Each locking- lever 22, corresponding with the purchase price, is connected to a toothed segment 111 which drives a spur-wheel 112 and rack 114. This rack slides upon a second rack 115, which engages with the driving- wheel 118 of the corresponding type-wheel 119, . Figs. 1 and 10, and with the driving-wheel 116 of the corresponding indicating-wheel 117. The typewheels 119<a-d> are fixed on concentric hollow shafts, while the indicating-wheels 117 turn loosely upon a shaft 117<a>. A rack 122 jointed to the rack 115 is pressed by a spring 123 against the ratchetwheel 124 of the counting-mechanism. The racks 114, 115 are connected together by a ratchet device 127, 128. As the wheels 117 are designed to indicate the amount of each transaction till the register is next used, the racks 115 return independently of the racks 114. With each rack 115 gears a spur-wheel 132, Fig. 2, fixed to a ratchetwheel 133, and turning loosely upon a shaft 136, to which is fixed a spur-wheel 132<a>. When the shaft 54 commences to turn forwards, a cam 142 (one for each wheel 132) acts upon the jointed end 141 of a lever 140, and by means of a link 144 lifts a pawl from the ratchet-wheel 133. A cam 201 on the shaft 54 then strikes a spring nose 200, pivoted to an arm 202 of a toothed sector, thereby turning the wheel 132<a> and shaft 136, and allowing each wheel 132 (which carries a tappet 135 arranged to be moved forwards by a pin 134 on the shaft) to revolve. The printing-device is contained in a case 149, Fig. 4, at the side of the cash register. The type-wheels 119 are placed side by side, and, in the return movement of the shaft 54, a cam 159 acts first on a lever 156, 155, which presses the tape 151 against the type-wheels, and then upon a lever 161, which rotates a ratchet-wheel 163, fixed to the receiving-roller, by means of a pawl 162. Each of these levers has a spring toe which yields in one direction. For transmitting motion from one group of stepped discs to another in the subtraction of the purchase price from the amount paid in, a device is made use of to enable the group of stepped discs on the extreme left to transmit movement to all the other groups, this transmission being interrupted only when one group is previously turned in the direction corresponding to the amount paid in. By the side of each stepped disc 3, 4, 5 is a second disc 167, 168, 169, Figs. 4 and 6, which is arranged to adjust to a value for the group less by one than the former disc. The stop 56 is fixed to a lever 171, pivoted to the adjusting-lever 46, and having a pin 172 arranged in the path of a helical segment 173, carried by a hollow shaft 174, one shaft serving for each group of discs. These shafts turn upon a fixed shaft 175, and have at one end an arm 176 which carries a pin 177 engaging from below with an arm 179 fitted to turn on the shaft 175. In a projection of the latter arm, a bar 181 slides, and has a slot embracing the shaft 175. The front end of the bar is pressed into a notch in a disc carried by the hollow shaft 183 of the group of discs. At the other end of each shaft is an arm 187, having a pin 188, which takes under a projection 185 on the bar 181 of the group to the left-hand side. When the discs turn in the direction corresponding to the amount paid in, the bar 181 is pushed back, forcing the projection 185 out of the path of the pin 188, so that no transmission takes place. When the disc turns in the opposite direction, the bar turns about the shaft 175, imparting a turning movement to the hollow shaft 174, and causing the helical segments 173, acting upon the pins 172 of the levers 171, to bring the stops 56 of the adjusting-levers under the second stepped discs. The movement of the lever 171 is resisted by a spring. A second spring 190 normally pulls down the arm 179 against a stopbar 192. To show when one of the coin receptacles needs re-filling, an arm 193 is provided which rests against the edge of the coins, and is connected by a lever to a rod 197.
