Patent GB-408975-A (GB)
Abstract: 408,975. Cash registers. NATIONAL CASH REGISTER CO., Dayton, Ohio, U.S.A.- (Assignees of Green, C. W. ; 106, S. 4th Avenue, Ilion, New York, U.S.A.) Sept. 19, 1932, No. 26067. Convention date, Sept. 19, 1931. [Class 106 (i).] In a cash register of the key set and operated type having a totalizer and a number of item and operation counters and associated printing and resetting means, a resetting operation is initiated by a partial idle movement of the resetting means for the totalizer and certain of the counters, a further operative movement of the resetting means being prevented until a total printing operation has been performed. The invention is described as applied to a machine of the kind disclosed in Specifications 135,465, 157,824, and 259,478, [all in Class 106 (i)], and provided with a totalizer, " Customers," " No Sale," " Paid Out " and " Reset " counters and date wheels, all of which are adapted to print on a tear-off report strip. In addition, known means are provided to print the item, date, consecutive number and clerk's -number on a voucher, and the item and consecutive number on a record strip. The machine is controlled for sub-total and total taking by manager's and auditor's locks both of which give access to the total printing mechanism, and the latter serving to free the resetting mechanism. Casings. The printing-mechanisms for the record and total report strips are enclosed by a normally locked hood 92, Figs. 9, 10 and 13, provided with an inspection door 93 to give acess to the paper. The hood is pivotally supported by brackets 96, 97 on a rod 90, one of the brackets 97 co-operating with a spring-urged detent 99 to hold the hood in open position and accelerate its closure. The opening of the hood is permitted upon operation of either the manager's or the auditor's lock (not shown) and gives access to the usual control and resetting levers 405, 377. The inspection door is also pivoted on the rod 90 and is held in its extreme open and closed position by a spring detent 104 carried by brackets 100<1> depending from the hood. In the event of the hood's being opened while the door is in open position, the rear edge of the door engages a fixed part 105 of the casing and holds it stationary, the opening of the hood thus serving to close the door. Printing sub-totals. After the unlocking of the hood 92, Fig. 10, and the adjustment of the control lever 405 to its right hand or total-taking position, a sub-total may be printed by depressing a knob 400 to force platens 388 into engagement with the wheels of the totalizer and counters. Actuation of the platens is prevented, when the control lever is not in total-taking position, by the abutment of a stud 489 on the platen carrier with a locking lever 491 mounted on a shaft 492. However, the adjustment of the control lever to the right, through a link 498 and a stud 502 on the locking lever, adjusts a notch 503 in the latter in the path of the stud 489 to permit printing. A sub-total is distinguished by a symbol " S " printed under the control of the actuating means for the " Reset " counter described below. The control lever is normally locked by a slotted rod 429, engaging with one of a series of notches 439 in the lever, the rod being moved axially to an ineffective position upon the actuation of either the manager's or auditor's lock. Printing totals. The resetting lever 377, Figs. 10 and 11, is normally locked by the rod 429 engaging a notch 438 therein, and is freed only upon the axial adjustment of the rod by the auditor's lock. The lever is connected through a segment 477, gearing and lost motion mechanisms, to the slotted shafts 302, 337 of the totalizer and counters, respectively. The resetting lever is further locked, when the control lever is in any position other than that for total-taking, by the locking lever 491, a stud 497 on which engages within a notch 496 in a link 494 pivoted to the resetting lever. Upon being freed by actuation of the auditor's lock and adjustment of the control lever, the resetting lever is capable of a small idle movement terminated by the abutment of a stud 505, thereon, with a notch 509 in a dog 378, urged clockwise about its pivot 379 by a spring pawl 506. Further movement of the resetting lever is prevented until after a total has been printed, and return is prevented at this time by a full-stroke lever 507. Upon the actuation of the platens, a pitman 511 connected thereto is moved to the left and by means of a shelf 513 engages beneath a pin 514 on the dog 378, rocking the latter to free the resetting lever. At the same time, a pin 515 on the dog disables the full-stroke lever 507 and the pawl 506 takes over a shoulder 519 on the dog to hold the parts in position until the operation and return of the resetting lever, when they are released by a stud 522 on the control lever camming the pawl 506 counter-clockwise. To prevent a printing operation while the totalizer is partially reset, the link 494 is adapted to cam the stud 497 upwardly to remove the slot 503 from the path of the stud 489. The stud 489 by its engagement within the slot 503 serves to lock the control lever during printing. The resetting lever and operating keys are interlocked by a disc 530 on the main shaft 31, an arcuate slot 531 in which co-operates with a shaped part 532 of the lever to prevent movement of the one when the other is out of normal position. A total is indicated by the symbol " G " printed under the control of the actuating means for the " Reset " counter described below. Counting number of resetting operations. The initial idle movement of the resetting lever rocks the dog 378, Figs. 10 and 11, slightly counter-clockwise to cam a stud 376 upwardly and thus rock an operating bail 372 for the " Reset " counter idly clockwise about the shaft 337. At the same time, a printing element fast with the bail is shifted from a position in which it prints " S " to one in which it prints " G." The bail is returned to actuate the counter and restore the printing element upon the next actuation of the customer counter, i.e. upon the next machine operation. Resetting consecutive-number counters. The consecutive-number counters for the vouchers and record strip printing-mechanisms are mounted on grooved shafts 53, 124, respectively, Fig. 13, and are reset by an upward and downward movement of a lever 457, pin-and-slot connected to a toothed segment 460. The upward movement of the lever through the segment 460, link 470 and sector 441 rotates the shaft 53 to reset the counter for the voucher strip, and through the segment 460, pinion 464, arm 466, link 467 and sector 1170 rotates the shaft 124 idly. Conversely, the downward movement of the lever rotates the shaft 53 idly and the shaft 124 operatively to reset the counter for the record strip. This resetting mechanism is normally locked by a lever 443 abutting the sector 441. The lever is disabled upon the rocking of a shaft 452 in one direction or the other by the manager's or auditor's lock, the lever being connected to the shaft through a pin 454 projecting from an arm 453 into a cam slot in the lever.
