DUNNING, OF ALLIANCE, OHIO, ASSIGNOR TO THE MCCASKEY REGISTER I A COMPANY, OF ALLIANCE, OHIO, A CORPORATION OF OHIO DUAL CASH REGISTER Application filed January 18, 1930. Serial No. 421,831.

The invention relates to cash registers and more particularly to a register having two independently operating adding and recording units.

The object of the improvement is to provide two'adding and recording units mounted upon a single base in which is located a cash drawer, one of the units being adapted for receiving and totaling all of the items of each transaction and being so constructed that the cash drawer is not opened by the operation thereof; the second unit being adapted to receive the totals of transactions entered on the first unit and being provided with a tier of keys for designating the clerk who made the transaction, the cash drawer being arranged to be opened only when one of said keys is depressed.

A further objectof the improvement is to provide means for operating the printing and adding mechanism of both units by a single operating handle; and to provide means for preventing the record strip upon each unit from operating when the other unit is being operated.

The above and other objects may be attained by constructing the register in the manner illustrated in the accompanying drawings, in which Figure 1 is a top plan view of the improved dual cash register;

Fig. 2, a longitudinal sectional view through the same;

Fig. 3, a perspective view of the mechanism through which the cash drawer is automatically opened when the second unit is operated;

Fig. 4, a detail sectional view through the rear portion of one unit showing the mechanism for operating the record strip when the unit is operated and for preventing operation of the record strip when the other unit is operated; and

Fig. 5, a perspective view of portions of the operating shafts of both units.

Similar numerals refer to similar parts throughout the drawings.

.Two adding machine units, designated generally at 10 and 11 are mounted upon a single case 12 containing a cash drawer 13.

A conical spiral compression spring 14 may be mounted in the rear end of the case 12 and adapted to be compressed by the rear end of the cash drawer when the same is pushed rearward into the case, as best shown in Fig. 2 and a lock plate holding member 15 may be mounted on the rear end of the drawer and provided with an aperture for receiving the bolt latch member 16 to lock to the drawer in closed position.

The bolt 16 protrudes downward through a guide opening in the bottom plate 17 of a bracket 18 secured to the top of the case, and the bolt is pivotally connected to the rear end of a rock arm 19 secured upon a rock shaft 20 journaled in suitable hearings in the bracket 18.

The rock shaft 20 is provided with a crank arm 21 pivoted at its upper end to aconnecting bar 22 extending forward in the case, and is also connected with an expansion spring 23 secured to the rear end of the case, acting to hold the lock bolt downward in engagement with the lock plate 15.

The rear end of the lock plate is preferably beveled downward and the lower end of the lock bolt is correspondingly beveled, so that when the drawer is pushed inward, the bolt will be pushed upward against the action of the spring 23 until it enters the aperture in the lock plate, into which it is pushed downward by action of the same spring, and at the same time the conical spring 14 is compressed, by the rear end of the drawer, so as to push the drawer forward whenever the lock bolt is released from the. lock plate. A

The forward end of the connecting bar 22 is pivoted to the upper arm 24 of a bell crank fulcrumed on a spindle 25 carried by a bracket 26 secured to the top of the case. The lower arm 27 of the bell crank extends forward under a point to which the lock releasing plunger 28 is adapted to be automatically moved when the clerks designating key on the second unit is depressed, as will be later described.

The releasing plunger 28 is mounted for vertical sliding operation in a guide barrel 29, wherein it is normally held upward by the coiled spring 30 located around a reduced portion of the plunger between the bottom of the barrel and a shoulder 31 at the upper end of the reduced portion.

The guide barrel is secured in an aperture 32 in the plate 33 mounted for sliding in a transverse guideway 34 secured to the top of the case. The bottom of the guideway and the top of the case are provided with registering transverse slots through which the guide barrel depends.

The constructionand arrangement above described permits a limited transverse sliding of the slide plate 33 in the guideway, so

that the release plunger may be moved out wardly from its normal position to a position directly over the arm 27 of the bell crank, when the second unit is operated, as will be later-described.

The parts are thus so arranged that by pushing the plunger 28 downward, when in the operative position, it will push the arm 27 of the. bell crank downward and through the bar 22 will operate the releasing mechanism to withdraw and disengage the lock bolt 16 from the lockplate 15, but when the plunger is shifted inward, to its normal position, it may be pushed downward without impinging the arm 27 of the bell crank and will not operate the lock releasing mechanism. 3

Means for holding the releasing plunger 28 in its shifted or inoperative position may include a bell crank 35 operating upon a vertical fulcrum36 secured within the case of the cash drawer, one arm 37 of the bell crank extending past the outer side of the releasing plunger guide barrel and the other arm 38 extending laterally in rear of the bolt 39 of the lock 40. v

This stopping means is so arranged'that when the stop bolt is withdrawn, the bell crank-is free to swing and permit the releasing plunger to move outward into operative position when the second unit is operated, as shown in Fig. 3, but that when the releasing plungeris shifted inwardto the normal, inoperative position, the stopping bolt 39 may be operated against the lateral arm 38 ofthe bell crank'and bring its rear arm 37 against 7 the outer side of the barrel :29, stopping the same frombeing shifted outward interoperative position, thus preventing opening of the cash drawerif desired. 7

v The transverse shaft 42 of the first adding machine unit, indicated generally at 10, is locatedadjacent to the rear side of the releasing plunger 28, the upper end of which extends upward in front of the shaft, when in the operative position, as shown in Fig. 3. 7 Upon the shaft 42 is secured a rock arm 43 which nay be in'the form of a cam, so located that its forward edge 44 will operate against the upper end of the releasing plunger 28, when the same is in the operative position, and will push the plunger downwardto actuate the lock releasing mechanism by ly through the unit 10 at a point, spaced above the operating shaft 48, and has at its right-hand end a-vrocke'r arm 51 to which is pivotally connected a link 52 pivotally attached at its other end to the'arm 43 upon theshaft 42. V y

it rocker arm 47a is fixed upon the inner or left-hand end of the operating shaft 48 and connected by a link 46a with the rocker arm 45a upon the transverse shaft 42a located through the second unit 11. ratchet segment 53 is upon the inner or left-hand end of the countershaft 50 and a similar segment-53a is lined upon the shaft 50a of the second unit and is pivotally connected, as by the link 52a with the rocker arm 43a on the shaft 42a. 7

A double pawl is pivoted above the segments and 53a and normally urged toward theposition shown in F 5, as by a spring As the shafts 50 and 50a are rotated counterclockwise, the teeth upon the segments 53 and 53awill ride over the pawls 54 which will prevent clockwise movement of the segments until the last tooth of each segment has passed over the pawls 54, atwhich time the segments may return to normal position without interference by the pawls.

The sliding plate 33 is pivotally connected, by a link 56, with one arm 57 of a bell crank which is fulcrumed, as at 58, upon any stationary portion of the device, a coil spring 59 being connected to said arm and to a stationary portion of the mechanism and adapted to normally urge the bell crank in the direction of the arrow shown in Fig. 3.

The ot Aer arm 60 of the bell crank has pivotally connected thereto a bar 61, located beneath the unit li'and extended to therear end except as modified and described for the pur pose of the present improvement.

7 The keyboard of the unit 10 may include sin rows of keys indicatedat 64, operatively associated with the usual mechanism for adding and recording items in dollars and cents.

' The unit 11 is provided with the rows of keys indicated at 64a forrecording and adding transactions in dollars and cents and with A toothed the row of keys indicated at 65 bearing letters or other symbols designating the clerks or at tendants, and if desired, with a row of keys 66 for indicating the goods or subject matter of the purchases.

A plurality of levers 67 corresponding in number to the rows of type bars, is provided in each of the units 10 and 11, these levers being pivoted as at 68 in the frame portion of each unit indicated generally at 69. Each lever is adapted to be swung forward upon its pivot, upon the operation of the machine, if any key'in its corresponding row has been depressed.

The upturned end 62 of the bar 61 is adapted to be engagedby the lever 67 corresponding to the row of keys 65 in the unit 11 where by the plunger 28 is'normally held out of the path of the cam 44 and only moved into the path of said cam upon operation of the unit 11 after one of the keys in the row 65 has been depressed.

As the corresponding lever 67 is moved away from the upturned end 62 of the bar 61, it will be seen that the spring 59 will pull the parts into position to bring the plunger 28 into the path of the cam 44, thus causing the plunger to be depressed and through the bell crank 2427 and link 22 the cash drawer is released and thrown open by the spring 14.

Each of the units 10 and 11 is provided with the usual platen roll 70 mounted on the rear end of the case covering the units and in front of the platen roll the usual type bars 71 are operatively mounted. The ink ribbon 72 is mounted on the spools 7 3 for operating around the posts 74 and between the key bars and the platen roll. A type bar 71a is preferably provided on the unit 10 for printing and adding, through the usual adding mechanism, the number of items entered into this unit in each separate transaction. 7

A record strip roll 7 5 is rotatably mounted on a bracket 76, in rear of the platen roll. whence the record strip 77 passes forward over a guide 78, thence under the platen roll and thence upward around the forward face of the same between the ink ribbon and the V platen roll.

A ratchet wheel 79, on one end of the platen roll, is actuated by a spring detent 80 to rotate the platen roll a limited distance each time a record has been imprinted on the record strip by swinging the operating handle-49, all in well known manner.

A reel 81 may be carried above the record roll as by the bracket arms 82 for winding the record strip thereon as the same is unwound from the record strip roll, and this reel may be geared to the platen roll by the belt 83 whereby with each rotation of the platen roll the record strip is unwound from the record strip roll and wound upon the reel 81.

In order to prevent the record strip on either unit from unwinding from its record roll when the other unit is being operated, a mechanism is provided including a lever 84, corresponding in position with the lever 67 of the key row 65 of the unit 11, and a similar lever corresponding with the lever 67 of the type bar 71a, said levers being pivoted as at 85 upon the frames 69 of the units, the lower end of each of said levers being normally held in engagement with the lower end of the corresponding lever 67 as by a pull spring 848 while the upper end of each of the levers 84 normally'engages under the bead 86, upon the plate 87 pivoted as at 88 upon the frame and having the spring detent 80 pivoted thereon as at 89, the pull spring 90 normally urging the detent upward upon its pivotal point.

The usual rocker shaft 91 is provided in each unit with the rocker arm 92 arranged to rock downward with each operation of the operating handle 49. The bar 98 is pivoted, as at 94, upon the rocker arm 92 and normally held beneath the bead 86 to prevent operation of the spring detent 80. V

\Vith this construction it will be seen that the record strip roll will not be unwound upon the unit 11, unless a key in the row of clerks designating keys in that unit has been depressed; nor will the record strip in the unit 10 be unwound unless a transaction is recorded on that unit, which will cause the corresponding lever 67 to move inward and the lever 84 to swing outward from beneath the bead 86, permitting the pivoted plate 87 to swing downward upon its pivot as the bar 93 is depressed by the operation of the handle.

The spring 90 will pull the spring detent 8O upward and into contact with the ratchet 79, advancing the same with each operation of the parts as above described and as the parts return 'to their normal positions, the bar 93 will rise, moving the pivoted plate 87 and detent 80 back to the inoperative position and permitting the lever 84 to return to its position beneath the bead 86.

Thus it will be seen that when either adding machine unit is operated, the record strip roll of that unit only will be unwound, the record strip roll of the other unit remaining stationary.
