Abstract: 597,903. Change computing and delivering apparatus. HOPE, C. June 29, 1945, No. 1664] [Class 27] In apparatus having change-computing mechanism operated differentially by coin-receiving means and by means for setting-up the sales amount, the delivery of change is controlled by feelers which engage suitably contoured members, such as rotatable slotted discs, forming a part of the computing mechanism. The coin-receiving means comprises a series of rotatable compartmented units for the different denominations, and these units are turned stepwise from a datum line as the coins are inserted separately into successive compartments. Operation of a change key then causes reverse rotation of such units, and by such an amount, as is necessary to bring the appropriate change coins opposite an ejecting device, this selection of the units and the extent of their reverse rotation being determined by the feelers in co-operation with the contoured members of the computing mechanism. The machine shown handles notes as well as coins. The receiving units are rotary drums 62-64 and 73-78. There is a copper section comprising the drums 62, 63 and 64, for the three copper coins, and a copper sales-setting drum 65 all rotatable about a copper computing sleeve 54, and a similar silver section comprising silver coin drums 75- 78 and a silver sales-setting drum 81 on a silver computing sleeve 55 coaxial with the copper sleeve. In addition, there is a ten-shilling note receiving drum 74 and associated sales-setting drum 80, and a pound note drum 73 and salessetting drum 79. Transfer gearing connects the copper and silver computing sleeves, and there are interlocks with the note-receiving sections which have no computing mechanism. Note-receiving mechanism.-Each note-receiving drum 73, 74 comprises a pair of axially spaced discs with opposed pairs of radial shelves 83, Fig. 6, forming the pockets 82. A tendered note is folded, laid through an opening 85 on to a shelf 86 and a cover 87 closed down on it. A key 96 is then depressed and this, through a pawl 107 on a rocking frame 106 connected by a link 105 with the key, steps the drum clockwise to bring an empty pocket opposite the note which is then thrust in by a slide 102 operated by the key through a link 101 and bell-crank 99. A feeler lever 93 pivoted at 92 blocks movement of the key in the absence of a note, but is rocked clockwise to free the key for a full movement by contact with the note during its initial movement. As notes accumulate they are stripped from the drum by a blade 114 and pass to a till 116. Coin-receiving mechanism.-Similar mechanism, Fig. 8, is associated with each coin drum 62-64 and 75-78, the drum being stopped by a pawl 107, and the coin inserted by a slide 102 both actuated by a key 96 locked by a feeler lever 93 in the absence of a coin. Sales-setting mechanism.-The sales-setting drums 65 and 79-81 are substantially identical. That for silver comprises a drum 81, Fig. 5, loose on the silver computing sleeve 55 and provided with finger apertures corresponding to values in steps of sixpence up to nine shillings and sixpence. The salesman inserts his finger in the appropriate aperture, and draws it down to the bottom of a slot 168 in the casing so turning the drum anticlockwise the appropriate amount. When released, the drum is returned by a spring drum 163 and cord 162. Totalising mechanism 195, connected through pawl and ratchet mechanisms 193 with all the drums, records the total sales. Change -computing mechanism.-Each coininsertion key 96, Fig. 8, in the copper and silver sections has a feed pawl 155 pivotally connected to it at 156 and controlled by a pin-and-slot connection 153, 154 with the lever 106A carrying the feed pawl 107 for the coin drum. Depression of a key 96 consequently moves its pawl 155 lengthwise and, after a predetermined lost-motion, the pawl engages and turns a ratchet wheel 71 clockwise an amount appropriate to the coin. The three ratchet wheels 71 of the copper section are secured to the copper sleeve 54, and the four ratchet wheels of the silver section to the silver sleeve 55. At the completion of the paying-in operation therefore, these sleeves are turned clockwise an amount corresponding to the total copper and silver coins respectively inserted. The copper and silver salessetting drums each have a driving pawl 174, Fig. 5, normally held clear of a ratchet 72 by engagement with a fixed stop 177. When a sale amount is being set up, the pawl moves clear of the stop, engages the ratchet 72 and turns it anticlockwise an amount appropriate to the sale. The two ratchets 72 are secured respectively to the copper and silver computing sleeves which are therefore brought back to a position corresponding to the charge due. Change delivery mechanism.-In accordance with the invention for each denomination of coin there is secured to the copper or silver computing sleeve a slotted control disc 57-59 and 67-70. These discs 'are each engaged by a spring-loaded feeler 122, Fig. 8, when a single change key 214, Fig. 6, is depressed, the feelers being connected with the key by means of a rock-shaft 215, arms 217 and slip couplings 218. Each feeler also carries a pawl 225 adapted to turn its respective coin drum back a number of steps dependent upon the upward movement of the feeler and that is determined by the depth of the slot in the control disc and consequently the position of the relevant computing sleeve. As shown in Fig. 8 the florin disc 68 has shallow slots 197 which result in no movement being given to the florin drum, intermediate slots 198 which result in backward movement of the drum through one step to bring one full coin pocket opposite a discharge chute 161, and full depth slots 199 which -result in -backward movement of the drum through two steps. The rock shaft 215 also actuates ejectors 226 located between the drum halves and which eject such coins as are brought opposite the discharge chute 161 which conveys them to an external tray 52. Delivery of a ten-shilling note is similarly effected by an ejector 226, Fig. 6, after backward movement of the drum 74 by a pawl 225 controlled by a feeler 122 which coacts with a selector segment 117 having a single slot 118 and rotatable about sleeve 55. When the pound note inserting key 96 is depressed the rocking frame 106, which carries the driving pawl 107 for the pound drum 73, also turns the segment 117 anticlockwise by engagement with a roller thereon so bringing its slot 118 opposite the feeler 122 in order that a ten shilling note shall be issued with the change. Pawls 124 and 125 hold the sector displaced until this has occurred. Interlocking and transfer mechanism.-The pawls 124 and 125 are controlled respectively by the ten shilling sales drum 80 and the two coin sales drums 81, 65 so that, if the sale exceeds ten shillings, both pawls are released, the segment returns at once to normal and the ten shilling note is not discharged. Delivery of a ten shilling note is similarly prevented when one has been tendered, and also when a pound note is tendered with coins. Each of the coin change control discs is identical and complete in each of its four quadrants, and transfer gearing interconnects the copper and silver sections. If the copper sleeve is turned back beyond zero, a pawl 179, Figs. 1 and 5, carried by an arm 178 on it momentarily drops into an aperture 185 in a fixed disc 184 as the zero is passea, so engaging and carrying back a ratchet 182 secured to the silver sleeve, to deduct sixpence from the silver change, the copper change being correspondingly increased. The silver sleeve cannot be turned back beyond zero unless a note of either kind is inserted, this, by the rocking of the frame 106 or lever 106A as the note is being inserted freeing a pawl 202, Fig. 3, from notches 201 at the zero positions of a disc 200 on the silver sleeve. The copper sleeve is similarly locked against movement beyond zero if no silver or note has been inserted. Modification.-In a modified construction, the ten shilling note-receiving drum also actuates the silver computing sleeve which has an extra control disc for determining delivery of ten shilling notes. The ten shilling setting-drum is omitted, and the shillings drum scaled in steps of one shilling to nineteen shillings. The copper drum is scaled in pennies to elevenpence, and an additional drum has a single halfpenny step.
