Abstract: 18,956. Marks, E. C. R., [Morris Cash Register Co.]. Aug. 23. Autographic cash recorders with item-printing mechanism.-Several check-strips are combined with a single record-strip, upon which notes may be written, the items being printed upon one of the check-strips and upon the record-strip by means of a typewriter having lateral-spacing and tabulating mechanisms, and the strips being fed forward and the cash-drawer simultaneously unlocked by the operation of a key appropriate to the check-strip. Drawer interlocks.-The cash-drawer has upon its sides longitudinal flanges 29, Fig. 2, which ride on rollers 28 near the front of the casing; a third roller 30 is mounted on the rear of the drawer itself and runs upon a fixed central rail 32, the outward movement of the drawer being effected by a spring 34 upon the raising of a drawer bolt 37, the lower bevelled end of which is adapted to pass through a slot 38<a> in a liorizontal plate 38, secured to the back of the drawer, and turned down at its rear portion. Inward movement of one of the drawer-andfeed keys 67<a> rotates, by means of a universal bar 69 and associated link-work, a collar 39<a>, the ratchet upper surface of which lifts an oppositely-shaped collar 40 fast upon the drawerbolt and suitably restrained against rotation. The drawer is thus freed, and when it is shut by the operator the turned-down portion of the plate 38 cams up the bolt until it can engage in the slot and re-lock the drawer. Keys for special transactions; delivering check to customer. - The record-strip 46 is the full width of the cylindrical platen 43 and its right - hand portion is accessible through a writing-aperture 110<a>, Fig. 1, in the cover-plate for the purpose of making notes. To the left of this, four check-strips 53 ... 56, assigned to various classes of transactions and preferably of distinctive colours, are situated side by side and pass over the platen above the record-strip, suitable inking-means being provided whereby items may be printed on the upper and lower strip simultaneously by the levers of a typewriter. Operation of one of the drawer-and-feed keys effects feeding-movements of the record-strips and of the check-strip to which it is assigned as follows. The spindle 48, upon which the recordstrip supply-roll 47 is mounted, fits into a socket 48<a>, Fig. 12, at one extremity, and is braked by means of a flat spring 48<f> secured to the socket; the other end of the spindle rests in a socket 48<b>, Fig. 13, with an upward aperture 48<c> closable by a hinged bar 48<d>. The take-up roll, upon a spindle 50, mounted similarly to the supply spindle, is provided with a ratchet feed-mechanism 50<b>, 51 operated from the universal-bar 69 of the drawer-and-feed keys. The check-strip 53, for example, is fed from a supply roll 66, the four rolls being mounted in a spring-controlled position upon a common spindle and each provided with a detent wheel, blade-spring, and washer whereby rotation of one roll is not transmitted to the others; the strip then passes through a flat-tube 53<a> which is bent around a feed-roller 58 and the platen 43, and is considerably cut away opposite each in order to expose a portion of the check-strip. Rollers 58<a>, mounted in spring arms, press the check-strip against its feed - roller, which has an emerv surface and is held loosely upon a spindle 58<1>, Fig. 7, between collars 60 with an interposed spring tending to produce engagement between opposing clutch - teeth 61<b>, 61<a> upon adjacent faces of the roller and of a loosely - mounted pinion 61 respectively, thus constituting a oneway clutch, adapted, upon the oscillation of the pinion by a segment 63 as the key is operated, to rotate the roller in one direction only. The feed of the check-strips is greater than that of the record-strip. Item-printing mechanism. - A typewriter of the top-strike lateral-movement kind is provided and, by means of tabulating-mechanism, may be positioned to print upon any one of the checkstrips. Key-levers 78<c> are pivoted upon a rail 79 and have at their rear ends segments engaging other segments upon the type-levers 78, the spring press-rods 83<a>, 85<b> retaining the parts in normal position. The whole of the keyboard and type-lever mechanism is mounted upon a framework having rollers for movement upon transverse rails and continually urged to the right by means of a spring drum 92, Fig. 16, and a cord 93. Depression of any key, including a space-key 85, raises a universal escapement-operating bar 81, thereby, through suitable connexions, moving the spring rod 88 rearwards and causing its flanged front end to carry with it a spring-controlled escapement rockframe 89<a>, mounted on a fixed part of the machine, which carries rigid and movable pawls for engagement with a rack 91 and adapted to produce a step-by-step movement of the typewriter framework. The tabulating-mechanism for positioning the typewriter to print on any one of the four check-strips consists of three keys 95<c>, each adapted to bring a rearwardlyprojecting lug 96 into the path of a lug 94 upon the travelling framework, and further to disengage the escapement pawls so that the framework may be arrested in such position. An inkribbon 100 passes, from a roll 101, above all the check-strip impression apertures, over a guideroll, and back between the record and the checkstrips to a roll 102, the two rolls and their operating-pinions 101<b>, 102<b> being mounted upon a spring-controlled rock-frame, which may be manually set for engagement of either pinion with a rack-bar 105 moving with the travelling framework of the typewriter, whereby the direction of feed of the ribbon may be reversed.
