P. A., Stockholm, Sweden Application September 25, 1939, Serial No. 296,379 In Sweden August 31, 1938 2 Claims. (Cl. 235-437) The present invention relates to a device in cash registers, bookkeeping and calculating ma— chines of the kind provided with amount or i2 rigidly united with the frame of the machine, said member strives through the action of a spring 54‘ extending between said pin H and a pin l3 ?gure key banks and one or more salesmen’s or on the member to assume the position shown in transaction key bank. One object of the inven Ci Figures 3 and 6. In the plate l2 there are fur tion is to produce a simple and reliable device ther secured cylinder or Yale locks I5. To the for locking by means of a removable key the inner ends of the locking cylinders l6 there are depressable keys of each salesman’s or transac ?xed pins or projections l1. When the mem bers 8 and the locking cylinders l8 assume their tion key bank. Another object is, in a device of this kind, to provide means for preventing locking of the keys oi a key bank, as long as any key in said bank is depressed. Still another object is to produce a cash regis positions shown in Figures 3 and 6, in which po sitions the keys cooperating with the locks can be removed, each of the pins ll rests against one ter of this type in which the key bank locks and . the zeroizing lock are arranged for selective op eration, so that the zeroizing mechanism can function only when the key banks are locked position. and vice versa. 56 is rotated in the direction indicated by an ar edge E8 of a recess i9 made in the respective member. A rocking outwards of the respective plate 4 is thus impossible, unless the respective locking cylinder i6 is brought out of locking When this is to take place the locking cylinder One embodiment of the invention is illustrated 20 row in Figure 3. The pin ll will now cooperate on the accompanying drawings, in which with the edge 20 of the recess it, said edge serv— Fig. l is a front view and ing as cam or guide surface, the respective mem Fig. 2 is a side view of a device according to the invention. Figures 3, 1i and 5 show details of the device assuming various positions and Figures 6 and 7 show on a larger scale sec tions on the lines VI—VI and VII-VII in Figures 3 and 4 respectively. Figure 8 is a detail view of the interlock slide. 7 On the drawings the salesmen’s or transaction key bank I is provided with eight keys 2 divided into two groups, the keys of the group 3A being intended for actuation by one salesman and the form a rocking movement away from the key shanks and ?nally reach the inactive position shown in Figures 4 and 7. In this position the pin H on the locking cylinder will prevent the member 8 from being returned to the initial posi tion by the spring (4. The keys may now, with out being prevented by the rail 4, be depressed, and Figure '7 shows how the pin 6 of a depressed key has passed the free edge of the plate 4. salesman. In order to give each salesman a pos The retaining of the keys in the depressed posi sibility of locking his keys, 1. e. to prevent a de tion is provided for by the common locking rail pression of the same, it has been arranged as 22, only visible in Figures 6 and 7. follows: In order that a salesman shall not be able to Along each of the key groups 3A, 3B there 40 lock his keys before all keys have resumed their extends a plate 4, one edge of which is turnable inactive initial positions the member 8 has a around a shaft 5 mounted in the key bank striking surface 2|, positioned relatively to the (Figures 6 and 7). The free edge of the plate 4 turning centre [6 of the locking cylinder in such may thus be rocked away from and towards the a way that the pin H, as is shown in Figure 5, respective key shanks, the latter being provided 45 strikes against said surface before the locking with pins or projections 6. These pins are cylinder has reached the position that allows re adapted to cooperate with the free edge of the moval of the key. In this position the spring I4 plate 4, when the same assumes its position is prevented from returning the member 8 and shown in Figure 6 i. e. rocked towards the key the plate 4 to their initial positions, since the shanks, and to prevent a depression of the keys. 50 plate 4 abuts against the pin 6 of the depressed To enable a locking of the plate 4 in this key key 2, as indicated with dot-dashed lines in Figure 7. locking position there is formed a projection 1 on the plate, which projection enters a slot 9 in a In the embodiment shown on the drawings member 8. The latter is provided with a notch there is between the two locks serving for lock~~ l0 entered by a pin II, which is ?xed'to a plate 55 ing the salesmen’s or transaction keys at third keys of the group 3B for actuation by another 7 ber being thereby against the action of the spring id displaced in the direction indicated by an arrow in Figure 6. At the displacement of the member 8 the corresponding plate 4 will also per v2 2,284,884. lock 23, by means of which a member ‘24 united with the zeroizing device of the machine may be actuated. Since, for several reasons, the sales be able to enter amounts on another salesman’s keys. It is, however, of no less importance that the salesmen shall not be able to lock their keys men’s or transaction keys should be locked dur until all keys have returned to their inactive posi ing the zeroizing, said device is constructed in 5 tions and that the person performing the zeroiz such a Way that it is impossible to insert a key ing shall not have any possibility of actuating the into the lock 23 before the keys have been re moved from the locks l5, i. e. before the keys 2 salesmen’s or the transaction keys. Several embodiments are, of course, possible have been locked. ' For this purpose there is pro within the scope of the invention and the device vided a slide 25 behind the locks l5 and the lock 10 may advantageously be modi?ed in order to cor 23. This slide is provided with a guide‘ slot 26 respond to various demands in various machines and three semicircular openings 21, 28 and 29 without giving up the idea upon which the in (Figure 8), said openings being positioned in vention is based. such a way that, when the slide assumes the po Having now described my invention, what I sition shown in Figure 1, the keys corresponding 15 claim as new and desire to secure by Letters to the locks 15 may be inserted far enough to Patent is: enable a turning of the locking cylinders. The 1. In a cash register including at least one inner end portions of the keys then enter the re 'salesman’s or transaction key bank having a plu— rality of depressible keys, a rockable member cesses 21, 29 of the rai1'25, the shape of said re cesses allowing a turning of the respective keys. hinged on an axis parallel to said key bank, said member having an edge portion extending along The recess 28, on the other hand, is, when the slide 25 assumes the position shown in Figure 1, said key bank and being rockable into and out of the path of a portion of each key in said key located beneath the key-hole of the lock 23. The key to said lock cannot, therefore, be in bank, resilient means urging said member into a serted far enough to enable a turning of the locking cylinder. Thus, no zeroizing can be ef fected when the portions assume the positions shown in Figure 1. If, however, the keys are removed from the locks .15, it will be possible to move the slide 25 1 from the position shown in Figure l and upwards until the guide pin 30 in the guide slot ‘12$ strikes against one end of said guide slot. The slide then assumes such position that the recess 28 al lows an insertion of the key into the lock 23 far enough to allow a turning of the locking cylinder. When the slide 25 assumes this position it is, however, impossible to insert any of the keys of the locks is to the necessary extent. In order to prevent a zeroizing of the totalizers key locking position in which its edge projects into the path of said key portions, a locking de vice to be operated by a removable key, and a re ciprocable link connected with said member and positively cooperating with a movable portion of said locking device to rock said member into a position in whichrsaid keys are freed for depres sion when said locking device is unlocked and to prevent locking of said locking device when said rockable member is not in its key locking position, each key including a portion disposed in the path‘ or" a portion of said rockable member when said key is depressed, whereby said rockable member cannot be restored to its key locking position and said locking device cannot be locked as long as any key in said key bank is depressed, of the machine, unless the person performing said operation has ?rst made it possible to ob 2. In a cash register including at least one salesman’s or transaction key bank having a plu serve the totalizer or totalizers, the slide 25 is rality of depressible keys, an elongated plate provided with a projection 31 serving as a ?nger rockable about an axis parallel to its longitudinal edges and to said key bank into and out of a key grip. Said projection 31 is of such shape that, when the slide 25 assumes the position shown in locking position, resilient means urging said plate . Figures 1 and 2, the projection will be located a cover 33 covering the totalizer or totalizers, said cover being preferably hinged and lockable. The into its key locking position, each'key having a shank carrying a projection adapted to cooperate with a longitudinal edge of said plate to prevent depression of the key when said plate is in its key locking position and with one of the plate slide 25 cannot, consequently, be displaced from its position shown in Figures 1 and 2 until the plate to its key locking position while said key between the edges that are formed by a station ' ary portion of the casing of the machine and surfaces when an effort is made to return the cover 33 has been opened and the tctalizer or totalizers have been made visible. 7 i w in) is depressed, a locking device to be operated by a removable key, and a reciprocable link connected As will be clear from the above the invention with said member and positively cooperating with does not only offer a simply constructed, space a movable portion of said locking device to‘ rock saving and reliable locking device for the sales said plate into a position in which said keys are men’s or the transaction keys, but the present freed for depression when said locking device is device prevents also such false and injurious op 60 unlocked and to prevent locking of said locking erations as are caused in earlier machines, often device when said plate is not in its key locking only due to lacking attention, in which machines position, whereby said locking device cannot be looked as long as any key in said key bank is there is no mechanical devices at all for prevent ing such false operations. Especially in cash registers that are used by several salesmen it is of 65 special importance that one salesman shall not depressed. _ I . KARL MATTS VIGBORG.
