Abstract: 765,449. Cash registers. NATIONAL CASH REGISTER CO. Jan. 31, 1955 [Feb. 25, 1954], No. 2785/55. Class 106 (1); In a cash register or similar accounting machine having a plurality of control keys with one adapted to control two different functions, separate counters are associated with this key for the two functions, one counter is normally selected and the other by depression of certain other ones of the control keys in the immediately preceding machine operation. The invention is applied to the machine described in Specification 730,839, the present machine including a row 2 of item classification keys 115-119, Figs. 1 and 2, in addition to the row 1 control keys of the earlier machine for dealing with multiple-item transactions. The keys of row 2 each have an associated counter 126-130 besides which there are a " no sale " counter 131, a "paid out " counter 132 and a " customer " counter 133. The same key 114 is used for multiple-item total taking and " no sale " operations and, according to the invention, this key is adapted to actuate either the " customer " counter 133 or the " no sale " counter 131 in dependence upon whether or not a key of row 2 has also been depressed and its counter actuated during the immediately preceding machine operation. Row 2 transactions counters. The row 2 transaction keys 115-119, Fig. 2, are item classification keys and one of these keys is always operated with the key 112 or 113 of row 1 in item entering. The special counters 126- 130, Fig. 1, for these keys are each actuated once by operation of the corresponding row 2 key except that, in a multiple-item transaction, no row 2 key actuates its counter more than once. A pitman 372, Fig. 23, depends from the actuating yoke of each counter, as 130, and a stud 371 on the pitman is adapted to coact with a corresponding one of series of angularly offset stop arms 370 secured to a shaft 365 adapted to be positioned by the row 2 differential 159. A spring 389 urges the pitman against a common control rod 388 whilst an actuating rod 379 engages openings 377 in the lower ends of the pitmans. Cams on a main shaft 208 are adapted first to move the rod 388 rearwardly, then to move the rod 379 downwardly and upwardly and finally to restore the rod 388 forwardly. The pitman corresponding to the depressed row 2 key is held by its stop arm 365 in the normal forward position of Fig. 23 during the rearward excursion of the rod 388 and the rod 379 engages a surface 378 of the pitman opening 377 so lowering the pitman and advancing the corresponding counter. As regards the other counters, their pitmans 372 move rearwardly with the rod 388 and present a downward extension. of their openings 377 to the rod 379 and are not lowered by the rod to advance their counters. A restoring bail 399 is moved downwardly by the actuated pitman and, in the case of multiple-item transactions, is only moved upwardly to restore actuated pitmans upon finally actuating the key 114 to clear the multiple-item totalizer. In this way, second and further actuations of the same row 2 key in the same multiple-item transaction are not registered on the counter. Row 1 transaction counters. These comprise a " customer " counter 133, a " no sale " counter 131 and a " paid out " counter 132. The " customer " counter 133 is advanced at each actuation of the single item key 113 or multiple-item total key 114. The " customer " counter is not, however, advanced unless a key of row 2 has also been actuated, indicating a sale, since the key 114 is also used alone to initiate " no sale " operations, which are not registered by the counter 133 but by the counter 131. The actuating yoke 436, Fig. 26, of the " customer " counter is connected by a lever 434 and bell-crank 400 to the bail 399 and is moved in the take-up direction when the bail 399 moves downwardly, as described above, due to actuation of a row 2 key. A pitman 414 depending from an arm 415 free on the countershaft 361, is held up to a rod 425 by a spring 432 and has an angle slot 416 engaged by a rod 417. A " customer " stop 410 coacts with a roller 407 on the pitman and is positioned by the row 1 transaction differential 158. Cams on the main shaft 208 first move the rod 425 rearwardly, then the rod 417 upwardly and downwardly, and finally restore the rod 425 forwardly. Depression of either key 113 or 114 positions the stop 410 opposite the roller 407; this prevents rearward movement of the pitman 414 with the rod 425 and the pitman is, therefore, moved upwardly by the rod 417 so that an extension 439 restores the bail 399 upwardly to advance the " customer " counter, provided the bail 399 was moved down initially by actuation of a row 2 key with the key 113 or 114. In a " no sale " operation, initiated by operation of the key 114 without a key of row 2, the pitman 414 functions idly since the bail 399 remains in its upper position of Fig. 26. With the bail 399 remaining in its upper position, one of its supporting arms 401, Fig. 28, by means of a stud 452, positions a stop arm 454 opposite a roller 458 on a " no sale " pitman 459 similar to the " customer " pitman 414. With the stop arm 454 so positioned, the pitman 459 is raised and then lowered by the rod 417 to advance the no sale counter 131. In any other than a " no sale " operation, the stop arm 454 is moved clear of the roller 458, either by downward movement of the bail 399 due to actuation of a row 2 key, or by direct action of the row 1 differential in a " paid out " operation initiated by the key 110. With the stop arm 454 moved clear, the pitman 459 moves rearwardly with the rod 425 and is not moved upwardly by the rod 417 to actuate the " no sale counter 131. Actuation of the " paid out key 110 positions a stop arm 412, Fig. 26, opposite a roller on a " paid out " pitman (not shown), similar to the pitman 459 and adapted similarly to advance the " paid out " counter 132 when the stop arm 412 is so positioned.
