in wil INVENTOR FrederioK LFuller BY M ATTORN EYS Patented Apr. 7, 1931 ULNHTED STATES PATENT OFFICE FREDERICK L. FULLER, OF ILION, NEW YORK, ASSIGNOR TO REMINGTON ARMS COM- IANY, 1130., A CORPORATION OF DELAWARE CASH REGISTER Application filed September 29, 1922. Serial No. 591,317.

This invention relates generally to cash registers and has particular reference to improvements in cash registers of the multiple drawer type.

One object of the invention is to provide an improved construction for selectively operating a plurality of independent cash drawers.

Another object is to provioe an improved 19 mechanism for selectively ringing bells or sounding equivalent alarms to call at ention to the opening of the diii erent drawers, in connection with mechanism for preventing such alarms when desired.

In the accompanying drawings the improvements are shown in one form which they might take when applied to or embodied in a machine of the type shown and described in U. S. application Serial No. 9 263,125 vtiled Nov. 19, 1918, by Frederick L.

Fuller, as well as British Patents 135,465;

157,823; 157,82 and 157, granted for the same invention. This embodiment is only illustrative, however, as the improvements are capable of modification and change to 1 ermit applying them to machines of various types and it is the desire not to be limited to the form herein shown and described.

ld ith the above and other objects in view 39 the invention consists in a novel combination and arrangement of parts, the features of novelty of which are pointed out in appended cla- .s, and a preferred form of embodiment ot which is hereinafter described with reference to the drawings accompanying and forming a part of this applicafion.

Of said drawings:

Fig. '6 is a detail perspective view of the drawer releasing mechanism with several parts omitted and others broken awayfor the sake of clearness, also a part of the bell hammer actuating devices.

Fig. 7 is a top plan view of certain details of the drawer releasing mechanism and 00'- operating parts.

Fig. 8 is a plan view of the control lever and its index plate.

Fig. 9 is a vertical transverse sectional view of the machine showing the means for rotating the main operating shaft and means whereby the totalizer and item type wheels are actuated differentially by the amount keys.

The machine shown in the acompanying drawings has the usual value keys 4 pivoted upon a rod 5. Resting upon the rear ends of the keys is a key coupler 6 pivoted at 7. WVhen the outer ends of the keys are depressed the key coupler is rocked clockwise (Figs. 1 and 9) and a nose 8 enters notches 9 formed in the rear ends of the keys 4. The purpose of such coupler mechanism is well known in the art and need not be discussed here.

Each value or amount key 4 is provided with an upwardly extending arm 10 carrying a stud '11 co-operating with slots 181 (Fig. 9) in plates 121, the slots 181 being graduated in such a manner that the depression of the amount keys will impart a differential movement to a frame 131 to which the plates are secured. Rigid with each frame 131 is a segmental rack 141, meshing with a pinion 151 secured to a corresponding item type carrier 12 so that movement of the seg ment by operations of a key sets upon the type carrier a number corresponding to the value of the key depressed.

It is to be understood that the amount keys are arranged. in banks and that for each bank there is a differentially actuated frame 131, a segmental rack 141 and an item type carrier 12.

Rotatably mounted below the item type wheels 12 and engaging the segmental racks 141 are pinions 161 and 162 attached to the numeral wheels of totalizers designated as A and B in Figs. 1 and 9 of the drawings. The totalizers may be utilized for the purpose of registering amounts for separate departments or clerks and have manipulat-ive means associated therewith in order that eithertotalizer may be operated so as to register amounts of the various transactions. The item recording and totalizer engaging mechanism is not directly involved in this invention and for a more detailed description of the form employed in the illustrative machine reference may be had to the Fuller application above-mentioned.

Extending transversely of the machine is a shaft 13 designated as the main operating shaft. This shaft is given a complete rotation at each operation of the machine and carries cams and other devices for operating various parts of the mechanism. The mechanism for accomplishing this comprises a vertically reciprocable plate 170 9) pivotally connected to the key coupler 6 and carrying rack bars 171 and 172 which'alternately mesh with a pinion fast upon the shaft 13 as the coupler is reciprocated. In this manner a complete reciprocation of the rack plate will effect a complete rotation of the main operating shaft 13. This mechanism is not described here in detail, it is old and well known in the art.

As shown in Fig. 9 there is provided a ratchet wheel 173 secured to the shaft 13 against which bears a pivoted spring pressed pawl 174 to prevent retrograde motion of the main operating shaft 13 and insure a complete operation of the machine.

At the extreme left end of the keyboard are two keys denoted by reference character 2 (Figs. 1 and 3) which may be used as departmental or clerks keys. These keys may have various functions such as totalizer selecting and engaging, setting a special type carrier and operating a special indicator. They may also have another special function whereby when either of them is depressed through a small arc of movement it lifts he coupler to a predetermined point and arrests it at this particular point. This point is known as the coupling point and when the coupler is in this position, other keys may be connected thereto. By now further depressing any amount key which has bee connected to the coupler the transaction may be completed. These functions constitute no part of the novelty of the present invention and suitable mechanism for carrying them out is fully disclosed in the Fuller application and British patents hereinbefore mentioned. I v

The means whereby the coupler is lifted to the coupling point by either of the keys 2 comprises "a coupler lifting cam surface 1 1- (Fig. 1) formed on the rear end of each of the keys 2 and co-operating with a face 15 on the rear edge of a shoulder on the coupler 6. The rear side 16 of the notch in each key 2 provides a stop face which engages the front ed e of the shoulder of the coupler and stops the motion of the keys. The coupler is retaincd in its lifted position by the pawl and ratchet mechanism 173v and 174; (Fig. 9) hereinbefore described.

The machine as herein disclosed has a centralized locking mechanism which controls the manner in which the machine is to be operated as well as accomplishing other functions such as looking the register, re leasing the drawers, conditioning the machine for printing totals and resetting the totalizers and counters. v

The mechanism for accomplishing the various controls mentioned comprises a lever 17 (Fig. 1) pivoted on the shaft 18 and provided with a downwardly extending sector arm 19 carrying teeth 20. Mounted on the key shaft 5 adjacent to the right side of the machine is a gear sector 21. Secured to the gear sector 21 is a somewhat larger gear sector 22 in mesh with a gear sector 23 fast on the shaft 24. (Figs. 1 and 3). Near the center of the machine this shaft carries a cam plate 25 (Figs. 6 and 7) provided with a nose 27. Pivoted to the base of the machine as at 28 (Fig. 2) is a drawer catch release lever 29 arovided with a rearwardl extendin b hook 30 and an upwardly extending hook 31 adjacent the key coupler. To the front of the pivot 23 the lever carries pivoted at 33 an upwardly extending pawl 32 provided with a tail 34 bearing against a pin 35 carried by the drawer catch release lever.

The key coupler 6 is provided with a downwardly extending trip arm 36 in line with the pawl 32 which is held forward in the path of the arm 36 by a spring 37. A drawer catch 38 is pivoted to the base of the machine at 39 and is provided with a notch 391 against which bears a bracket 40 carried by the upper cash drawer 101. A spring 41 (Figs. 1 and 6) is connected to the catch 38 and the release lever 29.

The locking lever 17 is provided with a handle 12 extending through and slidable in a slot in the cabinet (Fig. 8) and is provided with a pointer 43 movable over a scale 171 which bears at proper points words which designate the manner in which the machine maybe operated or controlled. When the locking lever is oscillated to the position indicated by Closed drawers as shown in Fig. 8, the oper tion of the parts thus far described is as follows: On the downward stroke of'the keys the coupler is moved upwardly and the trip arm 36 forces the pawl 32 rearwardly until the arm clears the pawl whereupon the pawl will swing back into the path of the trip arm. On the return stroke of the keys the coupler descends and the arm 36 strikes the pawl 32, thereby rocking the release lever 29 about its pivot and causing the hook 30 to clear the catch 38 with the result that the drawer operating spring 44 forces the upper cash drawer 401 open. Since the rear end of the lever 29 is then no longer supported by the catch, the spring 41 will rock it downward about its pivot, causing its hook 31 to overlie the-coupler, and thereby locking the coupler and keys until the drawer is closed.

Slidably mounted on the shaft 24 and the shaft 28 is the locking slide 45 formed with a slot 46 embracing the shaft 28 and a slot 47 embracing the shaft 24. Secured to the shaft 24 is a cam 53 (Figs. 2 and 7) similar to cam 25 and provided with a nose 54 and a notch 55. The slide 45 is provided with a stud 48 extending into the notch 55 on the cam 53 and with an inwardly extending hook 49 (Fig. 6) which overlies the coupler and is adjacent to the hook 31.- The lower edge of the locking slide 45 is formed with a notch 50 and a horizontal edge 51, (Fig. 2) either of which may co-operate at times with the pin 35 carried by the drawer catch release lever 29 as will be hereinafter described.

When the locking lever 17 is rocked to its extreme forward or Lock register position the sector 20 will rock the sectors 21 and 22 in a counterclockwise direction, causing sector 23, shaft 24 and its attached cam plate 53 to rotate in a clockwise direction. The cam slot 55 has engaged the stud 48 and forced the locking slide 45 rearwardly, causing its hook 49 to overlie the key coupler and lock the machine against operation.

If the locking lever is now moved rearward one step to the Opened drawers position, the notch 55 in the cam 53 will force the stud 48 and attached locking slide 45 forwardly, thus withdrawing the hook 49 from the key coupler. In this position the pin 35 will contact with the horizontal edge 51 of the slide and prevent the hook 31 from engaging the coupler when the drawer is open. It will, therefore, be possible to operate the machine without closing the drawer between operations.

It the locking lever be moved to thethird or Closed drawers position as has been described heretofore, the notch 50 will cooperate with the pin. 35 and permit the hook 31 to overlie the coupler. When the machine is operated with the lever set in this position it is necessary to close the drawer litween successive operations.

If the lever be raised to the fourth posi- 0 tion, the machine will be conditioned to allow the printing of totals and resetting of the totalizers and counters, but since this mechanism is not involved in this invention it will not be described in the application.

If the lever be raised to its extreme rearward or Release drawers position the cam plate 25 will be rotated in a counter clockwise direction sufiiciently to allow the nose 27 on the cam to engage a stud 52 carried by the forward end of the drawer catch release "lever 29 and rock the same about its pivot and thus release the catch 38 to permit the drawer to open.

A similar drawer releasing mechanism has been provided for the purpose of releasing the lower drawer 402 and the same will now be described. The key coupler is provided with a second trip arm 361 (Fig. 3) similar to the arm 36 of the upper drawer releasing mechanism and is in line with a pawl 56 (Fig. 7) pivoted to the rear end of the lower drawer catch release lever 57. The drawer catch release lever 57 is provided with a hook 58, the function of which is identical with that of the hook 31. The drawer catch release lever has in addition a rearwardly extending hook 59 (Fig. 6) adapted to co-operate with a drawer catch 60 which is suitably pivoted to the frame of the machine as at 61. The drawer catch release lever 57 is also provided with a pin 70 (Fig. 7) adapted to cooperate at different times with either the notch 50 or horizontal edge 51 of the locking slide 45. The pin 70 has its end formed preferably as shown and co-operates with the similarly formed pin 35. The purpose of this construct-ion is to provide a maximum amount of bearing surface between the pins and the releasing slide 45 which is common to both, as well as to allow an independent rocking movement of release levers 57 and 29.

A spring 601 (Fig. 2) is connectedto the release lever 57 and to a stud 62 carried by the forward end of the drawer catch 60 pivoted about a stud 61 (Fig. 6). The rearward end of the drawer catch is further provided with a transversely extending stud 63 to which is attached a link 64 the lower end of which is connected to an arm 65 secured to shaft 66. The shaft 66 is mounted between the side frames and carries a latch 67 which has a function similar to the drawer catch 38 of the upper drawer 401. The shaft 24 carries a cam 53 as aforesaid, the nose 54 of which is adapted to co-operate with a stud 68 carried by the forward end of the releasing lever 57. (Fig. 7.)

From the above description it is evident that upon the descent of the key coupler both of the drawer catch release levers 29 and 57 will be rocked about their pivots and cause the hooks 30 and 59 to clear their respective catches 38 and 60 to allow both drawers to pen.

When the locking lever is oscillated to the Closed drawers position the notch 50 will co-operate with the pins 35 and 70 to allow either the'hook 31 or the hook 58 to overlie the key coupler when the corresponding drawer is opened thereby locking the machine against further operation until the. drawer is closed.

In the Open drawers position the pins 35 and 70 will co-operate with the horizontal edge 51 of the slide to preventhooks 31 and 58 from engaging the coupler when either drawer is open. I

In the Release drawers position the noses 27 and 5 1 of their respective cam plate 25 and 53 will, engage the studs 52 and 68 carried by the drawer releasing levers 29 and 57' respectively to rock the same about their pivots to release both drawers.

From the above description it is evident that both drawers will be opened at each op eration of the machine, but, since it is desirable that each clerk obtain access only to his particular drawer, some means must be provided to prevent the opening of the other drawer and to this end the following mechanism is employed. Mounted to the right of each operating or clerks key is independently operated cam plate 7 3 or 74. Each cam plate is formed with a cam slot 75 and a dwell 76 as clearly shown in Fig. 6; with each of theslots is a'stud 78 carried by the rear end ofthe corresponding clerks key.

A tube 781 is journaled in a bracket consist ing of the side ears 80 and a bottom plate 81 secured to the base by suitable screws. To one end of the tube is secured the cam plate 73 and to the opposite end is secured a blocking arm 7 9. A shaft 83 passes thru the aforesaid tube or sleeve and has-likewise secured to it-at one end the cam plate 7 iand to the other end a blocking arm 84. -Asshown clearly in Fig. 6, the catches 38 and are provided with two studs 85 and. 86, respectively, normally resting slightly above the blocking arms 79 and 8-1. (Fig. 1.) The result of this construction is that whenever a clerks key is depressed to its coupling point its corresponding cam plate will be carried rearwardly by means of the stud on the key engaging the cam portion of the 'slot whereupon the blocking arm will berooked upwardly. As a result of the upward movement of the blocking arm the end of said arm will pass in front of the stud which is at.-

tached to the catch of the drawer which is to remain in closed position. g

Upon a further depression of the keys the stud carried by the clerks key will. enter the dwellof the camv slot and retain the blocking armin its upwardlyraised position. Upon the subsequent upwardor return stroke of the key the trip arms 36 on the keyv couplerv will trip the pawls on the drawer releasing levers and the hooks 30 and 59 will be raised from engagement with the drawer catches.v Only one drawer catch will be operated, however, since one of the blocking arms will be raised upwardly in the path of the stud carried by the drawer catch which, is to remain inoperative; The stud on the drawer catch which is,

' Jo-operating to be operative will pass over the upper edge of the blocking arm and the drawer will be released in the usual manner. From this it is evident that'whenever the drawer releasing mechanism of the lower drawer is eiiective, the clerks key which corresponds to the 9 lower drawer will cam plate 7 3 forwardly, whereupon the blocking arm 7 9 will be raised and render the upper drawer releasing mechanism ineffective. In the same manner the cam plate 74. will render the lower drawer releasing mechanism ineiective whenever the upper drawer is to be released.

As a precaution against one clerk surreptitiously opening the cash drawer of another clerk, there is provided a suitable alarm or bell mechanism which, normally is operated upon the opening of thecash drawers.

In the present embodiment this mechanism comprises two bells 90, and 91 (Fig. 3) one preferably constructed so as to ring out a tone distinguishable from the other when struck. Said bells are carried by studs 92 secured to the rear frame of the machine. l Vith the, exception that the bells'are constructed to give, different tones the bell mechanisms are identical and the following description will apply to both. I a

The bell striking mechanism consists of a yoke or frame 93 (Fig. 4) pivoted to the machine frame as at 94 and has integral or secured thereto a bell-hammer 95 normally lying near the bell. Movement of the frame 93 in, one direction is limited by a stud 97 secured to the machine frame abutting against a lug 971 integral with the frame 93. lhe frame 93 is, in addition, provided with a nose 98, the function of which will appear later. i l

Placed directly behind the rear end of the clerks keys are two vertical actuating bars 99 the lower ends being guided by screws 100 passingthrough elongated guide slots 101. The upper ends of the actuating bars are formed with bent over portions or lugs 102 which are normally directed in alinement with the rear ends of the clerks keys as clearly shown in Fig. 1. The width ofeach bent over portion is substantially the same as that of the keys and is normally engaged and lifted whenever aclerks key is depressed. The upper ends of the actuating bars are guided by passing through'slots 104 formed in a plate 103 5') mounted upon the machine frame in 'a manner whicn will hereinafter be described. The lower end of each actuating bar 99 is provided with a foot 105 to which is pivoted a trippawl 106. Said trip pawl carries a trip plug 107 which is directly-under the nose 98 of the frame 93 and adapted to contact therewith. A spring 108 connected to the lower end of the trip pawl and frame returns the actuating bar toits normal position. 7

The result of this construction is as follows: Whenever either clerks key is depressed its rear end will contact with the bent over portion 102 of the corresponding actuating bar 99 and raise said bar to the position shown in dotted line in Fig. 1 of the drawings. In so doing the trip lug 107 of the trip pawl will contact with the nose 98, the counterclockwise rotation of the pawl being prevented by the upper edge of the pawl bearing against a lug 109 formed on the foot 105 of the actuating bar. Upon a further depression of the key the frame 93 will be rotated against the tension of the spring 96 until the lug 107 passes over and clears the nose 98 whereby the frame will be quickly released to force the bell hammer against its respective bell and ring the same. As aforesaid, the spring 108 will tend to return the actuating bar to its normal position, and upon the descent of the same the lower edge of the trip lug 107 will contact with the upper edge of the nose 98, and the trip pawl will be rocked in a clockwise direction about its pivot until the lug clears the nose and the parts will then again assume their normal position.

It is frequently found desirable to operate the machine without ringing the bells, and means has been provided to move the lugs 102 on the actuating bars 99 out of the line of travel of the rear ends of the keys in order to prevent the tripping of the hammers of the bell mechanism.

The plate 103 (Fig. which, as before stated, is slotted to guide the upper ends of the actuating bars 99, is slidably mounted upon the frame of the machine by a guide screw 108 passing thru a bell crank lever 109 and an elongated guide slot 110 formed in said plate. One end of the bell crank lever is bifurcated to engage a stud 111 secured to the guide plate. The other end of the bell crank lever carries a stud 112 co-operating with a slot 113 formed in a link 1131. The forward end of said link is connected to a bell muffler lever 114 pivoted to the frame of the machine as clearly shown in Fig. 1.

The result of this construction is that whenever the bell muffler lever 114:15 rotated forwardly the. bell crank lever 109 will slide the guide plate to the left as viewed in Fig. 5. The bent over portions 102 of the actuating bars 99 are now out of line of travel of the rear ends of the keys and will not be lifted whenever a. key is'depressed. Any suitable means may be provided to retain the bell mufiler lever inits inoperative position so that the machine may be operated without actuating the bell striking mechanism. The operation will doubtless be understood from the foregoing, but may recapitulate to render sequential action of the various parts clear in the relation which they bear to each ther. p y

' it will be assumed that the clerk who has control of the lower cash drawer has made a transaction which he desires to register. The clerk operates his related key 2 (which in this case is the high key) and raises the key coupler to its partially elevated position at which point the desired amount keys may be attached to the key coupler. While the clerks key is being elevated to the coupling point its associated stud 78 will play in the cam portion 75 of the cam slot formed in its associated plate 73, thereby rocking the sleeve 781 to which it is secured. Upon a further movement of the key coupler by the depressed keys the stud 78 willplay in the dwell 76 of the cam plate. WVhile the stud was operating in the cam portion of the cam slot it rocked the tube 781 sufficiently to bring the locking arm 79 in front of the stud 85 carried by the upper drawer catch 38. During a further depression of the keys the arm 79 will be retained in'its blocking position and during the return stroke of the keys or a downward movement of the key coupler the trip arms 86 will actuate the trip pawls of both drawer releasing levers, thereby disengaging the hooks 30 and 59 from the drawer catches 38 and 60. The springs 41 and 61 which are secured to the drawer catches will tend to rotate them, but it will be noted that since the locking arm 79 has been placed in the path of the stud 85 it will prevent any movement of the drawer catch 38 related to the upper cash drawer. Since there is no locking arm in the path of the stud carried by the drawer catch related with the lower cash drawer, the drawer catch 60 is free to be moved about its pivot 61 and through the intermediate connections comprising the stud 63, link 64 and arm 65 will allow the movement of the rock shaft 66 and the drawer catch 67 so as to permit the exposing of the lower cash drawer.

\Vhenever the machine is adjusted to the position shown in the drawings and the cash drawer is left open, the hook 58 associated with the drawer releasing devices for the lower cash drawer will hook over the key coupler and lock the machine against another operation until the cash drawer is closed.

When the clerks key mentioned hereinbefore is depressed its rear end will contact with the lug 102 of the left bar 99 3) raising it upwardly and through lug 107 on the pawl 106 contacting with the nose 98 of the frame 93 will move the bell hammer 95 away from the bell 92 against the tension of of the rear ends of keys so that the bars 99 will not 'be' elevatedwh'enever a key is depressed. The mode of operation of the mechanism for releasing the upper cash drawer is similar to that just described in connection with lower cash drawer, with the exception that the other clerks key is operated. In this case the bell 92 will be struck emitting a tone quite different from that of the remaining bell 90. The present invention is preferably used in connection with cash registers having multiple counters, so that there may be a drawer and a corresponding counter for each clerk. By this arrangement the drawers and counters must balance and mistakes may be instantly located.

While the form of mechanism herein shown and described is admirably adapted to fulfill the objects primarily stated, it is to be understood that it is not intended to confine the invention to the one form' of embodiment herein shown and described, as it is susceptible of embodiment in various forms all coming within the scope of the claims which follow.
