Abstract: 811. Macbeth, G., and Macbeth, M Jan. 12, 1914 Cash registers with item-printing mechanism.-In cash registers in which racks for setting type-wheels or the like are carriedby members controlled for differential movement by keys, the racks have an initial movement independently of the gates, for the purpose of imparting a preliminary rotation of the type-wheels to ink the types. (1) In the machine shown, two racks 43, geared respectively to the pence and the shillings typewheels 72, 73, Fig. 6, have p i n-a n d-s lot mountings 46, Fig. 1, on vertically movable gates 20, the typewheels engaging inkrollers 81, Fig. 6. The two gates are arranged at the right and the left of the machine, opposite sets of keys for pence and shillings, the gates being provided with inclined bars 22, Fig. 1, adapted by engaging the projected keys to limit differentially the upward movement of the gates. The gates are tensioned upwards by springs 30 connected to levers 54, which are loose on a shaft 8 and are connected by links 55 to the gates, the springs being normally prevented from acting by weights 50, which rest on the levers 54. The weights are secured to the shaft 8 and are connected by a link 52 to an operating-lever 2 arranged between the two sets of keys. A frame 27, provided with bars 28 which normally engage the top inclined bars 22, is carried by links 29 and supports a bar 33 provided with a pin 35 engaging an arm 36 on a shaft 11. On operating the keys, the frame 27 is pressed back and the shaft 11 effects the release of a detent 39 for the lever 2 and a detent 42 for the racks 43, the racks being then lifted by springs 47 through a distance limited by the slots 46. This initial movement of the racks causes the type-wheels 72, 73 to rotate over the ink-rollers 81. On pulling forward the lever 2, the weights 50 are lifted, and the springs 30 then lift the gates, the racks rotating the type-wheels to select the types. Near the end of the outward stroke of the lever 2, a tappet 59 thereon lifts the bar 33 and releases the lever 36, springs returning the detents 39, 42 to the normal position. On returning the handle, the gates are pulled down by the links 55, and the racks are pulled down below the normal position by the engagement of the tappets 59 with lugs 62, and on being released by the tappets, the racks are moved upwards by the springs 47 into engagement with the detent 42. The springs 30 and the weights 50 may be replaced respectively by weights and springs. A rotary crank may replace the lever 2. The pence-rack 43 engages a pinion on the shaft 9 bearing a type-wheel 72 at each end, and the shillings-rack 43 engages a pinion 49 on a sleeve 77 geared by a shaft 79 to an alined sleeve, both sleeves having a shillings type-wheel. (2) The type-wheels for printing on the record-web are at the right of the machine, and the typewheels 72, 73 for printing on the ticket-web 83 are at the left of the machine and are associated with date or date and time printing wheels 84 which, before impression, are rotated over an ink-roller 81<x> by means of a spring-tensioned arm 93 controlled by a link 92 on the impressionlever 86, a slotted connexion 96 being provided to prevent movement of the wheels 84 during impression. Voucher-issuing.-The ticket-web 83, Fig. 6, passes between a spring-pressed feed-roller 99 and a feed-roller 98 having a free-wheel pawl connexion 97 with a pinion 95 engaging a sector 94 on the shaft 3, the feed occurring on the downward or return stroke of the sector. The platen hammer 85, formed with parts to engage all the type-wheels 72, 73, 84, is mounted on a slide and is lifted by a lever 86 loose on the shaft 3 and actuated by a tappet 87 on a rocking arm 88. The hammer is returned by a spring 82. The record-web is fed by a pawl carried by a wrist-plate on the shaft 3, the wrist-plate being provided with a tappet adapted to engage a platen-actuating lever. The tickets are cut off by a sliding knife 105, Fig. 6, actuated by a spring 109 on the tripping of a detent 106 by a tappet 107 on the sector 94. The trip is raised and the spring tensioned by a lever 184, which engages a cam 110.
