(Cl. E36-22) 2 Claims.

This invention relates to improvements in cash drawer operating mechanism for cash registers and accounting machines.

This application is a division of application Serial No. 116,004, filed by Warren P. Loudon on September 16, 1949, now Patent No. 2,528,774.

The invention is shown applied to a machine of the type disclosed in United States Patents No. 2,209,763, issued to Ernst Breitling on July 30, 1940, and No. 2,587,019, issued to Frank R. Werner on February 26, 1952, and in the co-pending United States patent applications of Frank R. Werner, Serial No. 46,165, filed August 25, 1948, and Serial No. 53,114, led November 3, 1948.

As pointed out in the above-named parent case, the invention is illustrated in a machine adapted for use by cooperative societies, and, as illustrated therein, the machine is adapted for use in Great Britain, where cooperative societies are well organized and consist of many cooperating stores.

The object of the invention is to provide a cash drawer operating mechanism which is disabled by a setting device on the keyboard to prevent release of the cash drawer when certain kinds of entries are made in the machine.

With this and incidental objects in view, the invention includes certain novel features of construction land combinations of parts, a preferred form or embodiment of which is hereinafter described with reference to the drawings which accompany and form a part of this speciiication.

Fig. 4 is a detail View of another part of the cash drawer releasing mechanism.

Fig. 5 is -a top plan View showing the cash drawer releasing mechanism and shows both the automatic and the manual release mechanisms for the cash drawers.

Fig. 6 is a detail view of a transaction manipulative device.

General description The cash drawer release mechanism disclosed herein is illustrated to be controlled by manipulative devices of a keyboard illustrated in the above-mentioned parent case. In such machines, the selective release of cash drawers is normally under control of a differentially settable manipulative device, which, as illustrated in the parent case, controls the entry of items by different clerks, since each clerk has a separate cash drawer allotted to her, the manipulative device controls the release of the clerks allotted cash drawer.

The illustrated machine also embodies a transaction manipulative device, and, when certain transactions not representing cash taken in are entered, this manipulative device disables the release of all the cash drawers.

Cash drawer mechanism The cash drawer cabinet 33 (Figs. 1 and 2) houses four cash drawers, 365, 386, 381, and 385. One cash drawer is allotted for each of four clerks; that is, one for each of the four positions of the clerks selecting lever Il'i. The cash drawers are suitably mounted on tracks on which rollers carried by the cash drawers run for each operation of the drawers when the drawers are released to move out of the cabinet 33. Each cash drawer is impelled outwardly by a spring 38S when released. Normally, latches 390 (shown in Fig. 3), 39|, 392, and 393 maintain the respective drawers in their inaccessible position. The latches 330, 395, 392, and 393 (Figs. l, 2, and 3) are selectively operated under control of the clerks selecting lever Il.

The cash drawers are arranged in two tiers, the drawers 385 and 361 being in the left-hand tier, and the drawers 336 and 386 being in the right-hand tier.

The latch 35B for the upper left-hand cash drawer 335 is pivoted on a shaft 39!! (see also Fig. 5), carried by a bracket 395, supported in the top of the drawer cabinet 33. The latch 396 is spring-urged, by a spring 356, into engagement with a. stud carried on an arm 852 secured to a shaft 853 journaled in bearings on the drawer cabinet 33. The right-hand end (Fig, 5) of the shaft 653 carries an arm 854 (Fig. 2) provided with a stud 855 projecting into a notch in the free end of a drawer release arm S56, pivoted on a shaft 857. The arm 85S is provided with an upwardly-extending arm 356, which lies in the path of a rod 397 (Figs. 1 and 5) carried between the two Iarms 39S of a yoke 399 when the clerks selecting lever ||1 is in its upper position. The yoke 399 is pivotally mounted on the shaft S59, supported in the frames -29 and 3Q. The arm c62 is provided with a roller 565, which lies in the path of movement of a cam 4&6 secured to the shaft |03.

When the machine is operated with the clerks selecting lever ||1 in its uppermost position, the rod 391 moves into engagement with the arm 335 and rocks the arms 390` and 056, together with the connections including arm 054, shaft 053, and arm 852, to rock the latch 390 counter-clockwise (Fig. 3) to release the upper left-hand cash drawer. The rod 301 is moved into engagement with the arm 306 when the cam 400 is rotated and engages the roller 405 to rock the yoke 403 clockwise. Clockwise movement of the yoke 403 moves the yoke 399, together with the rod 391, to the left (Fig. l) to engage the arm 300 of the latch mechanism to rock the latch 39@ counterclockwise to release the upper left cash drawer.

The latch 39| for the upper right-hand cash drawer 300 is pivoted on a stud 401 (Fig. l) carried by a bracket supported on the top of the cabinet 33. The latch 39| is provided with an upwardly-extending arm having a face l! l 9, which lies the path of the rod 331 when the clerks selecting lever ||1 has assumed its second position. The lever I |1 has pivoted thereto a link f* the lower end of which is pivoted to the rod nel', by means of which the rod 331 is positioned.

When the clerks selecting lever Il? is moved counter-clockwise into its second position (Fig. l), the link 420 lifts the rod 381 into the path ci the face M9. Thereafter, during machine operati-on, when the cam 405 rotates to rock the yoke liti) clockwise, the yoke 39,0, pulling on the rod 33?, rocks the latch 39| to release the second cash drawer.

The lower left-hand cash drawer 301 is held in closed position by a latch 302 (Fig. 2) having a stud Walid projecting into a slot 403 of a link M0. The link (lill is connected to an arm (il i (see also ll) clamped to a sleeve 412 on shaft 053. The sleeve extends toward the right (Fig. 5), where an arm. 4 3 is secured thereto, adjacent the befcrementicned arm 354. The arm 513 is provided with a stud, like stud 855 (Fig. 2) projectinc into a notch in the end of a bell crank- 4M, lar to the bell crank 856 but having a face one step higher than the face M0 on the latch 33S. When the clerks leve-r ||1 is moved into its third position, the rod 331 is moved opposite the face M5, and therefore, during the machine operation, when the rod 391 is moved by the cam (306, the rod 391, acting on the face M5, rocks the train of mechanism including the bell crank M4, the arm 4|3, the sleeve (llt, the arm i, the link M0, and the latch 302 to release the lower left-hand cash drawer.

The lower right-hand cash drawer 33t is provided with mechanism like that for lifting the latch The latch 333 for the drawer 3233 is connected to a link MS, which is connected to a bell crank having a surface 422 (Fig. 1). As the clerks selecting lever |11 is moved into its fourth position, the rod 391 is moved opposite the surface When the rod 301 engages the surface 422, the lower right-hand cash drawer 308 is released :y the mechanism including the cam 4103 and the yol-tes and 300.

A manual release is provided for releasing all ci the cash drawers when the proprietor wants 'to check the cash in the cash drawers without operating the machine. For this purpose, a slide (Fig. is provided. The slide 33d has formed thereon two cam surfaces, 423 and 42:4, which lie adjacent the bell cranks normally ope-rated by the rod 301 during machine operation. When the proprietor operates the control lock, described in the parent case, to remove a flange 342 from the right end 34| of the slide 333 in preparing the machine for printing totals, the slide 33B is free to be moved rightwardly (Fig. 5). When the ange 342 is out of the path of the slide 338, the proprietor` grasps a finger piece 425, formed on the left end of the slide 33S, and shifts the slide 338 to the right. Movement of the slide 338 to the right causes the cam surfaces 423 and 424 to wipe against the rear ends of the drawerreleasing bell cranks, rocking them counterclockwise to lift all of the latches 390, 39|, 392, and 333, thus releasing all the cash drawers simultaneously without operating the machine.

Drawer release control by transaction Zever The machine as disclosed in the parent case is provided with a setting lever 200 (Figs. 1 and 6) for controlling the machine for various transactions. One of the functions of the lever 200 is to control the cash drawer release mechanism.

An operation of the machine with the. transaction lever 200 (Fig. l) in its ninth position results in the cash drawers all remaining latched in closed position. To accomplish this result, the connection between the cam 406 and the rod 391 is disabled when the transaction lever is moved into the ninth position.

The drawer release mechanism is disabled by the transaction lever 200 by a stud 800 mounted on an extension thereof. The various positions assumed by the stud 800 are shown in chain lines in Fig. l. Lying in the path of the stud 860 is an. arm 08| forming an upwardly-projecting extension or one arm of a yoke 062. The left ends (Fig. l) of the two arms of the yoke 89E-2 are provided with clearance slots 8d3, through which the shaft Elli passes. The two arms 40| and 4t2 of yoke 03 are provided with the beforemention'ed L-shaped slots 864, through which the shaft 4&0 also passes. A spring 005 normally maintains the shaft 400 in a notch comprising the vertical section of the L-shaped slot 8M, so that the shaft |503 is normally effective to actuate the rod 391 in the manner hereinbeiore described. When the transaction lever 2?:0 is moved into its lowermost, or ninth, position, the stud 800 engages the arm 0%5 and rocks the yoke 852 to litt the shaft 400 out of the vertical section of the L-shaped slot 364. Thereafter, when the cam 405 actuates the yoke 403, the horizontal section of the slot 064 moves over the shalt 400; therefore the rod 391 is not moved, and the selected cash drawer latch is not actuated to release a cash drawer.

While the form of mechanism shown and described herein is admirably adapted to fuliill the objects primarily stated, it is to be understood that it is not intended to coniine the invention to the form or embodiment disclosed herein, for it is susceptible of embodiment in various other forms.

What is claimed is:

l. n a machine of the class described, the combination of a cash drawer, a manipulative device, a latch for normally maintaining the cash drawer in inaccessible position, an operating member engageable with the latch when operated to actuate the latch to thereby release the cash drawer for movement into an accessible position, a coupling rod carried by the operating member, a main shaft, a cam on the main shaft, a driving element actuated by the cam, a notch formed in the driving member to receive said coupling rod whereby the operating member is coupled to the driving member, a bell crank having a slot engageable with the coupllng rod, and means on the manipulative device to actuate the bell crank and thereby Withdraw the coupling rod from engagement with the said notch, y
