Abstract: 5348. Jackson, W. H. March 5. Tills.-Check-tills of the type described in Specification 12,620/07, in which the amount is entered on a ticket strip and duplicated on a record strip moving at right-angles to the ticket strip, and in which one or both sides of the ticket are printed by a printing-machine actuated by the operation of the till, are provided with (1) means by which a detailed bill can be issued, (2) improved means for interlocking the drawer, flash-plate, cover-glass, ticket-issuing gate, and the doors for insertion of the paper rolls, (3) means for easily changing the printing-rollers and for releasing the ticket paper from the grip of the printing-rollers when at rest, while at the same time it is gripped by special devices, thereby preventing fraudulent removal of a ticket, and (4) means for operating the duplicating-ribbon for the autographic record. Fig. 5 shows a section of the till at the line V, V, Fig. 1. Fig. 2 shows an inverted plan of the lid of the till. The drawer 2 runs on rollers or bowls and is provided with the usual rack and pawl to ensure a full stroke of the drawer for operating the apparatus. A can 11 on the drawer engages a projection on slide 8 moving in vertical guides and carrying a rack engaging a pinion 13 on a loose sleeve which, through a ratchet drives the shaft 12. The ordinary bell, registering-counter, and coin-displayers may be added if desired and be suitably actuated from the drawer, but are not shown on the drawings. The slide 18 is held up when lifted by the tooth 19 of the lever 21 so long as the drawer is opened far enough to allow the toe of the lever 21 to drop clear of the edge of the drawer. The shaft 12 operates the screw cam 22 for moving the take up roller 23 for the record strip; a cam 24 on the shaft 12 also moves the inking-ribbon rollers 29, 30 by means of a lever 36 actuating a double pawl 34 mounted on a pivot so as to be moved over and held by a spring to drive either of the rollers 29, 30, each of which is slotted in order to engage the ends of the lever 44 when the ribbon is all wound on to the other roller. The lever 44 then acts through the rocking frames 40, 37, so as to throw the driving-pawls 34 into engagement with the other roller 29, 30. The double pawl may alternatively be reversed by a hand device actuated from outside the casing, the end of the ribbon being distinctively coloured to indicate the necessity for reversal. The feed-roller 25 is actuated from the shaft 12 through a clutch device and draws the ticket paper from a roll (not shown) which is supported in slotted guides 87 and is inserted through a door 123 in the casing. The impression roller 52 and the inking-rollers 89 are mounted in bearings in lifting-frames 92 supported on a cross-bar 94, and are lifted clear of the feed-roller except while the drawer is being opened. The drawer carries a pawl 96, which engages a tooth 98 on a lever 99, which as the drawer is opened moves the bar 95 and removes it from beneath the lever 131 supporting the cross-bar 34, thus allowing the spring 91 to press the printing-roller against the feed-roller at the time the feed-roller on the shaft 12 is operated. In a modified construction, the ticket is passed from the impression rollers beneath the record strip and then out through a slot in the lid of the till instead of being pulled beneath the record strip and passed out through the gate 111, as shown. At the end of the movement of the drawer, the pawl 96 engages a tooth 101 on a lever 102, which replaces the bar 95 and lifts the rollers 89, 52. On the return stroke of the drawer, the pawl 96 is inoperative, being merely depressed against the action of the spring 97. To make a detailed entry on the record strip, the pinion 64 is turned by a milled head outside the case so far as is necessary to supply the required length of paper as indicated by a scale. The rack 63 is thus moved towards the back of the casing, moving with it a frame 55 carrying a glass plate 57 by means of a lug 58 thereon and a slot in the rack bar, and also rotating the pinion of the roller 23, thereby taking up through the pawl 70 and ratchet-wheel 71 a length of record strip of the same length as the distance through which the plate 57 is moved. The lever 72 is moved by a lug on the rack 63 so as to enter the depression 73 in the drawer, thus preventing the movement of the glass and the record strip while the drawer is open and ensuring the replacement of the glass when the drawer is opened. The total amount of the transaction is recorded on a further space on the record strip which is exposed by movement of the flash plate 75, as described in Specification 12,620/07. The lug 79 on the flash plate moves the timing-arm 28 about its pivot so as to present the slot 77 to the screw 27 on the shaft 12 and also swinging the stop 84 clear of the drawer lock 80. This latter ensures the operation of the flash plate, as, unless the lock 80 is removed, the drawer cannot be opened. When the drawer is open, the lock 80 lifts the rod 85, and this rod 85 prevents operation of the flash plate after the drawer is opened and ensures that the drawer cannot be opened until the flash plate is replaced to cover the entry made. The timing-arm 28 is replaced by the screw cam 27. The gate 111 through which the tickets are issued is pivoted on pins 112 and has a cam 114 which causes a pawl 121 to lock the shaft 12 when the gate is moved from its normal position. The opening-jaw 108 is mounted on a pivot 118 and is lifted by the engagement of a projection on the sliding frame 92 with the end 119 of the lever 117, and is closed when the printing-rollers are lifted by means of the spring 115. This grips the extruded ticket, and the serrated edges of the jaws facilitate its detachment. The door 123 through which a new ticket roll is inserted has a cam acting on a rod 125, which is spring-pressed by a spring 126 to lock the shaft 12 by the pawl 121 when the door is opened. A pivoted bar 132 with a knife edge or other gripping-edge mounted on pivots grips the paper if any attempt is made to move the paper backwards. Another gripping-edge 127 mounted on a bar 130, connected to the lever 131 grips the paper except when the drawer is open, and so prevents abstraction of length of paper between the jaws of the gate 111. For convenience of exchanging the printing-matter, the type or dies are fixed upon thin metal barrels 134 or upon strips of flexible material. The barrel 134 has internal projections 136, which enter grooves 137 in the cylinder 52, and is held thereon by a detachable flange.
