13 Claims.

In multiple drawer cash registers it has heretofore been old to press in a clerks key or rotating clerk's lever to select the drawer to be operated, which drawer is operated when the machine is operated. If, for instance, there are six clerks, a separate drawer being provided for each clerk, and. these clerks are designated by the letters A to F inclusive, the drawers are likewise designated by the same letters and when the clerk presses clerks key A or operates the lever so as to position the indicator corresponding to the position A when the machine is operated drawer A will be opened. It is sometimes desirable, however, to use a machine of the above description as a cashiers machine in which all of the drawers may be locked except one and this one may be any one of the drawers. The cashier still desires to register the sales made by the respective clerks but desires to open only the drawer which she 20 has selected, which may or may not be a drawer corresponding to the clerk whose transaction is being registered. Suppose she selects drawer B as the drawer which will always be operated. She would lock all of the other drawers but she would still operate the clerk's lever or key so as to register the sale as being made by the clerk, such as for instance, clerk F. I have provided novel mechanism whereby this result can be accomplished. Other objects and advantages of the invention will appear in the detailed specification and claims which follow.

In the drawings:

Fig. 2 is a side elevational view partly in cross section of the arrangement of the drawers and the mechanism whereby they are operated;

Fig. 3 is an enlarged detailed view of the coupling mechanism shown at the bottom of the shaft at the right of Fig. 2, which view is partly in cross section;

Fig. 4 is a plan view of the mechanism shown in Fig. 5; and

Fig. 5 is a side elevational view partly in cross section of the mechanismshown at the bottom of Fig. 1.

The clerks lever or key I is provided with a segmental gear 2 which meshes with and drives a pinion 3 which is connected with a pinion 4 which drives a gear 5 which drives a gear 6 connected to the clerk's indicator 1. The pinion 3 also meshes with and drives a segmental gear 8 rotatably mounted on a shaft 9, which segmental gear meshes with and drives a rack Ill on a slide rod II which is suitably guided by means of rollers l5 so that its motion is a simple up and down motion. The slide II is provided near its lower end with a rack l2 which meshes with and drives a pinion l3 mounted on a stud l4. The

pinion l3 meshes with and drives a pinion l6 secured to a shaft I! mounted in standards I 8, which standards are supported by the top H! of the drawer mechanism. Secured to the shaft I1 is a beveled pinion 2D. The pinion meshes with and drives a pinion 2i secured to a shaft 22, which shaft has secured thereto a collar 23 provided with a square socket 24 which as shown in Fig. 3 may receive a finger 25 of an arm 26 pivoted on a pin 2'! carried by a collar 28. As shown in Fig. 2 the collar 28 is provided with a prong 29 which is received within a groove 30 in a tube 3| which surrounds the shaft 22. The tube 3| is provided with staggered fingers 32 and with fingers 33, which are in alignment with each other; that is, one is directly below or beneath the other. These fingers normally lie in a plane directly beneath an arm 34 of a lever 35 which has a downwardly projecting arm 36 which may engage the fixed walls 31 behind the cash drawer to act as a stop. These levers 35 are normally pulled upwardly by means of springs 38. The levers 35 are provided with upstanding lugs 39 which at their forward end terminate in cam surfaces 40. The cash drawers 4| each carry a rear wardly extending arm 42 provided with a downwardly extending flange 43. When the drawer is pushed inwardly the flange 43 contacts the cam surface and cams the lever 35 downwardly until the flange 43 passes beyond the lug 39, at which time the spring 38 pulls the lever 35 in a clockwise direction so as to position the lug 39 behind the flange 43 and hold the drawer in its closed position.

The main drive shaft 44 of the machine is provided with a disk 45 which carries a cam 46. As viewed in Fig. 1, this shaft rotates clockwise and when it has practically completed its rotation the cam 46 engages a nose 4'! of a lever 48 pivoted on a shaft 49 pressing the said lever downwardly. This lever over-lies a slide rod 50 which in turn over-lies a flange 5| carried by a lever 52 pivoted on a stud 53 carried by a plate 54 mounted on the top 59. When the lever 48 is depressed as above described the rod 50 is depressed, which rotates the lever 52 counterclockwise as viewed in Fig. 1. This lever is provided with a stud 55 secured to a rod 56 which at its other end carries a stud 5'! connected to a bell crank lever 58 which has a finger 59 which is received between collars Gil secured to the tube 3|.

Let us assume that the first position of the lever I is the position in which the lever should be placed to register a sale made by clerk A. When clerk A rotates the segmental gear 8 he raises or lowers the slide rod ll, which rotates the shaft I! by means of the rack 12 and pinions l3 and I6, which in turn rotates the shaft 22 by means of the pinions 20 and 2|. As the shaft 22 -lever she does not rotate the tube 3i.

is rotated the collar 23 which is secured to the shaft 22 is likewise rotated and the collar 28 is also rotated by means of the finger 25, arm 26, and pin 27. This rotation of the collar 28 rotates the tube 3| by means of the tongue and groove connection 29 and 30. The parts are so arranged that if the topdrawer corresponds to clerk A, one of the staggered fingers 32 will be positioned immediately below the arm 34. corresponding to the clerks drawer A. Whenthe machine is now operated the cam depresses the lever 48, rod

50, and lever 52, thereby pulling the rod against the tension of the spring 5! which rotates the lever 58 in a counter-clockwise direction as viewed in Fig. 5 elevating the tube 3i by means of the finger 59 and the upper collar 50. As the tube 3| is thus elevated the topmost staggered finger 32 engages the topmost arm E l, rotating the upper lever 35 in a counter-clockwise direction as viewed in Fig. 2, thereby removing the lug 39 from contact with the flange 53 so that the drawer is freed and may be opened by the customary drawer operating spring which forms no part of this invention and is not shown. Precisely the same operation would take place if clerk B positioned the lever i to a position to indicate B on the indicator 7, in which case the lug 32 corresponding to B clerk would cause drawer B to be opened but would not open any of the other drawers.

If, however, the proprietor desired to use the cash register as a cashiers machine and wishes for drawer B alone to be opened each time the machine is operated regardless of how the operator may move the lever I, he would open the back of the machine and rotate the arm 26 in a counter-clockwise direction as viewed in Fig. 3, thereby disengaging the finger 25 from the socket 2 3. so that the rotary motion of the shaft 22 would not be imparted to the tube 3! He would new position all of the fingers 3S beneath the arms 34, this being possible when it is remembered that all of the fingers 33 are in alignment with each other, and if one is positioned beneath an arm 34 all of the other fingers 33 will be positioned immediately below their respective arms 3d. The shaft 22 is under no condition rotated as much as one complete revolution. The operator in positioning the fingers 33 beneath the arms 34 would have moved the sleeve 3i and arm 26 to such a position that the shaft 22 would not rotate the socket 2 5 into such a position that the arm 26 could again re-enter the socket. The operator is now free to move the lever I to indicate any clerk but when she so moves this It will be understood that each of the drawers is provided at its front end with the usual key lock, not here shown, and that the operator, when so usin the machine, will have locked all the drawers in their closed positions with the exception of the drawer which is to be used. When she now operates the machine the tube 3! will be elevated in precisely the same manner as when the machine was used as a clerks cash register and all of the levers 35 will be rotated counter-clockwise as viewed in Fig. 2 but only the drawer which is unlocked, of course, can be projected outwardly by means of its spring. It is obvious that it is immaterial which of the drawers the proprietor may select as the cashiers drawer so that this drawer and no other will be opened each time the machine is operated regardless of the posi tion of the lever I.

-I have, therefore, provided a means to convert the cashiers machine into a clerks machine, or vice versa.

I realize that many changes may be made in my invention without departing from the spirit thereof and I, therefore, desire to claim the same broadly except as I may limit myself in the appended claims.
