Patent GB-259478-A (GB)
Abstract: 259,478. White, A. E., (Remington Arms Co., Inc.). April 7, 1926. Cash registers with item-printing mechanism; printing totals; zeroizing-mechanism.-In a keyset and operated machine, such as that described in Specifications 135,465, 140,363, 157,823, 157,824 and 157,825, various interlocking devices are employed to ensure the correct manipulation of the item-entering, total-printing and zeroizing mechanisms so that no two of these can be operated simultaneously. The keys pivoted at 30 operate the main shaft 41 through the coupler 34 in the known manner and actuate the totalizer 57 and the item type-wheels 52 through the camslotted plates 44 and sectors 51. The totalizer is carried by a frame pivoted at 60 and rocked into and out of actuating engagement by cams 61 on the main shaft 41 acting through a bell-crank lever 63, cam-slotted plate 68, pin 70, pitman 71 and cam-slot 73. The record-strip is mounted by means of winding and guide rollers between the cheeks 80, 81 of a frame pivoted on a shaft 45 and normally bearing by its own weight against the main framework 23, the record-strip in this position being adapted to receive the item imprints from the wheels 52. The impression is given by a hammer platen 90 pivoted loosely on a shaft 89 and rocked by means of a spring- controlled hammer 95 pivoted to the printing- frame at 97 and provided with a trigger latch 99 co-operating with the part 101 of a lever 102 fixed to a shaft 86 rocked by a cam on the main shaft. The hammer 95 strikes against an arm 93 pivoted on the shaft 89 and connected with the platen through a spring-controlled clutch disabled by a manual lateral movement to allow the platen to be raised to give access to the type wheels, inking-ribbon &c. To print a total the printing- frame may be drawn forward by means of the lever 102 so as to position the platen above the totalizer whereupon the platen is automatically operated to print the total. The lever 102 in its forward motion first engages the trigger latch 99 and then as the entire frame rocks about shaft 45 a stud 140 on the lever enters a fixed cam groove and by further rotation of shaft 86 the trigger is released and impression effected. Covers and shields for the printing and counting devices. The salesman has access to the record-strip for replenishment purposes by means of a lid 26 provided with a window and writing- slot and normally fastened bv a hook 129 fixed to a shaft 127 rotatable by means of a lock 105. This shaft and lock are mounted on a cover 27 hinged at its lower edge and retained in position by another hook 128 secured to the shaft and engaging a lug 131 on the cabinet. Rocking of the shaft by means of the lock 105 is insufficient in extent to disengage the hook 128 but by positioning the function-controlling lever to the " total and re-set " position the manager rocks the shaft sufficiently to release both hooks and thereby free the lid and cover. The mechanism for this purpose includes a toothed gear connection between the lever and a. shaft 65 having a cam to rock a bell-crank 126 and, through an arm 1133, the shaft 127. The cover 27 carries a shield 150 for the totalizer which is further protected by a cover 151 supported by the main sideplates of the printing-frame. Preventing total-printing by salesman. While the cover 27 is in place the drawing forward of the printing-frame for the purpose of printing a total is prevented by means of an arm 109 secured to a shaft 563 and normally lying in the path of a pin 110 on the printing-frame. When the cover is turned down a. pin 1361 on an arm rigid with the cover, by traversing a cam slot 136 in an arm 138 fixed to the shaft 563, lowers the arm 109 to permit the forward movement of the frame. Locking the registering keys while the cover 27 is open. This is effected by another arm 139 secured to the shaft 563 and co-operating with the key coupler. Interlock between the printing-frame and the platen. One part of the clutch previously mentioned for connecting the platen with its actuating arm 93 is carried by the arm and when moved to the right (Fig. 6) to disconnect the platen a locking-edge 157 is brought above the frame 56 so that the printing-frame cannot be moved forward. When, on the other hand, with the clutch engaged, the frame is rocked forward the edge 157 will co-operate with the side of a cut 158 to prevent disengagement of the clutch and' consequently the lifting of the platen. Re-setting the totalizer. The totalizer shaft 58 is slotted at intervals to pick up the usual pawls on the type-wheels when it is axially displaced and then rotated. The rotational movement is imparted by a toothed sector 160, Figs. 2 and 7, forming part of a re-setting lever 1601 but normally the pinion 161 is out of alignment with the sector so that manipulation of the lever 1601 by the salesman will be ineffective. On the end of the shaft 58 is a knob co-operating with a cam 165 rigid with the rotatable barrel of a lock 166 riveted to the cover 151. Thus the manager after opening the lid and cover and inserting his key in this lock 166, can shift the shaft axially to render operation of lever 1601 effective. Full-stroke device, for re-setting lever 1601. The sector 160 carries a pawl 172 which, in the home position, Fig. 7, takes under a fixed lug 174 but when the lever is moved away. Fig. 9, rises, under spring action, and is held by a second pawl 178 so that complete restoration of the lever is impossible. At the end of the outward journey of the lever the pawl 172 abuts against a part 46 and being thus rocked counterclockwise is again held by the pawl 178 so that the lever may be returned to its normal position and the holding pawl 178 displaced to free the pawl 172. Access to the full-stroke device is prevented by a shield 180, Fig. 2, fixed to the sector 160 and a shield 188 secured to the pitman 182' referred to below. Interlock between re-setting-mechanism and the main shaft. To the re-setting sector 160 is pivoted one end of a guided pitman 182, Fig. 7, shaped at its lower edge to co-operate with a cut-away disc 181 on the main shaft. Thus with either of the co-operating parts out of normal position the other cannot be moved. Interlock between the total-printing and resetting-mechanism. A hook-shaped plate 190, Fig. 7, pivoted at 183 and slotted at 191 to engage a pin 192 on the pitman 182 is concentric at 194 with the shaft 45 so that the shaft 86 may pass freely, when the printing-frame is rocked to take a total, and simultaneously prevent movement, of the resetting-lever. Similarly when the latter is shifted the plate 190 hooks over the shaft 86 to obstruct displacement of the frame. Record-strip column lines, ruling. A block secured to the framework alongside the item typewheels is formed with four ridges to print lines longitudinally on the strip to form columns for the insertion of autographic notes as to quantities of goods sold &c.
