CASH

Application filed June 21,

This invention relates to attachments cash registers and the like and is more paticul'arly adapted to be used in connection with the type of cash register shown and described in Letters Patent of the United States issued to Thomas Carney, No. 497,860 on May 23, 1893, and to Joseph P. Cleal, No. 7185565, issued January 13, 1903.

The present device is shown attached to a. machine of the type illustrated in the above mentioned Carney and Cleal patents, said machine being constructed and operating substantially the same as the machines shown in these patents and more particularly that shown in the Cleal patent. An object of this invention is to enable a merchant selling ta);- able goods to keep an account of all sales and also to keep an accurate account of all money taken in as tax which is collectible by the Revenue Department of the Government. This is accomplished by arranging the parts of the machine so that before the merchant can register the amount of sale of goods, he must first register the amount of on said sale. If the saledoes not involve tax, a no tax key must be depressed before the amount ofsaid sale can be registered.

It is a. further object of the present invention to provide means for indicating the amount of tax, in addition to the regular means torindicating the amount of the sale. It the goods sold are non-taxable the machine will indicate no tax and the amount of the sale.

With these and incidental objects in view. the invention consists in certain novel tures of construction and combinations of parts, the essential elements of which are set forth in appended claims, and a preferred form or embodimeirt cat which is hereinafter described with reterence to the drawings which accompany and form part of the specification.

Fig. 14: is a detail view of the interlock between the tax register and :main register and shows the parts in the position they assume when a tax key has been depressed.

Described in general terms, the machine includes two separate keyboards, one for registering the regular amounts of a sale and one for registering the amount of tax on all taxable goods. These mechanisms controlled by said keyboards are so interconnected that a key in the tax'keyboard must be operated before any oi. the regular aiz'lonnt keys can be manipulated, thus 'insur he registration of the tax for each tax able sale. Proper indication is provided under the direct control of the keys.

Should a sale be non-taxable, a no tax key is provided and must be depressed before any of the regular amount keys can be operated thus indicating no tax.

Described in detail the tax registering at tachment includes two banks of keys 25 and 26 (Fig. 4). The keys 25 are for registering tens of cents and the keys 26 are for registering units of cents. A no tax key 27 is provided in the tens bank of keys for re leasing the machine and for indicating when a sale does not involve the taxation.

Means is provided for preventing the depression of more than one key at a time in a bank. This means includes lugs 28 (Figs. 1 and 13) secured to the keys 25 and 26, which cooperate with key stops 29 pivotally mounted on frames 30 (Figs. 1 and 4) can ried by rods 31 mounted in side frames 32 and 33. Secured to the frames 30 are cover plates 34 which have slots (not shown) through which the keys project and which serve as guides for said keys. The key stops 29 are so arranged that when any key is depressed its lug 28 will be moved between two of the key stops, rocking them apart and holding them in these positions thus closing the spaces between all the other key stops 29, which prevents any of the other keys from being depressed until the depressed key has been released.

The lower ends of the keys are pivotally mounted at 38 on differential drivers 39 loose on a rod 40 carried by the frames 32 and 33. The keys 25 and 26 are laterally spaced and guided at their lower ends by the drivers 39 and thin guides 41 mounted on and extend ing from the rod 40 to a rod 42 carried by the frames 32 and 33. These guides 41 are laterally spaced on the rod 42 by means of collars 43 (Fig. 9). Through this arrangement the differential drivers 39 and the keys are always held in perfect lateral alignment.

The differential drivers 39 are provided with slots 44 (Figs. 1 and 13). These slots 44 are graduated commensurate with the values of the keys. The group of differential drivers 39 for the units bank of keys is provided with slots graduated indentically the same as those shown in Fig. 1 associated with the tens bank of keys. The slot 44 in the driver 39 (associated with the no tax key 27) is not graduated but is a true are swung from the center of the rod 40 upon which all drivers 39 are pivoted. The purpose of this will be hereinafter described.

Cooperating with the slots 44 associated with the tens bank of keys, is a rod 48 carried by an arm 49 and a lever 50 rigidly connected by a sleeve 45 (Figs. 8) loose on a rod 51 mounted in the frames 32 and 33. Cooperating with the slots 44 associated with the units bank of keys is a rod 52 (Fig. 8) carried by an arm 53 and a lever 54 rigidly connected by a sleeve 46 loose on the rod 51. The rods 48 and 52 are held in their normal positions by arms 55 (Figs. 1, 8 and 13) loose on the rod 40, and held in engagement with said rods 48 and 52 by means of springs 56. Integral with the levers 50 and 54 are totalizer actuating segments 57 and 58 which cooperate with a tax totalizer to be hereinafter described.

From the above description it will be readily seen that when, for example, the 4 key in the tens bank is depressed the differential driver 39 to which this key is pivotally connected will be rocked clockwise, whereby the slot 44 in this driver will move the rod 48 downwardly, to rock the arm 49 and the lever 50 countercloclnvise and move the segment 57 upwardly to the fourth position, thus registering 4 on the tens totalizaer wheel, to be hereinafter described. When the rod 48 is once started downward, it, by its engagement with the edges 47 of the unoperated differential drivers 39, prevents any of the latter drivers from being moved.

The means for returning the key and the mechanism associated therewith to normal positions, includes an arm 59 (Fig. 1) integral with each of the differential drivers 39, each arm 59 having a slot 60 cooperating with a flattened rod 61 carried by a restoring arm 62 and a restoring lever 63 (Figs. 1, 8 and 13) fast on a shaft 64 carried by the frames 32 and Stretched between the rear end of the lever 63 and a stud 65 carried by the frame 33 is a restoring spring 66.

From this description it will be clear that when the differential driver 39 is rocked clockwise by the depression of the key, the arm 59 will be rocked clockwise, and through the slot 60 and the rod 61 rock the restoring arm 62, the shaft 64 and the restoring lever 63 counter clockwise, thus stretching the restoring spring 66. After the key has been re leased by means which will be hereafter described, the restoring spring 66, having been put under extra tension, will rock the lever 63, the shaft 64 and arm 62 clockwise and cause the rod 61 to force the arm 59 and consequently the differential driver 39 counter clockwise to normal position, thus raising the key to its normal position.

hen an operation of a key 25 and 26 is required to register a tax, these keys must be simultaneously depressed, because when any one of the arms 59 begins to rock clockwise upon depression of a key 25 or 26, this arm will cause the rod 61 to be moved to engage the projections 67 of all other arms 59, thereby preventing movement thereof, and consequently preventing depression of any other key 25 or 26. If, however, two keys are depressed simultaneously, the slots 60 of both arms 59, corresponding to the keys being de inc and pressed, will embrace the rod 61 thereby permitting continued depression thereof.

Means is provided for locking any 01" the tax keys or the no tax key in depressed position until after one of the amount keys has been depressed. Upon the depression of H he us, to be neleina rtei oethe regular amount scribed, this locking means is released and allows the restoring spring 06 to return the tax keys in the manner above described. This mechanism includes an arm 1, Sand 13) integral with tl stor' lever 6. Pivotally mounted on the arm To is a catch 71, the forward end of which is held in contact with a latch plate 72 by means of a spring 73 stretched between the rear end of a catch 71 and the pin T l, carried by the restoring lever 63. The latch plate ii is, mounted on two studs 75 carried by the frame hen the lever 03 rocked counter clockwise by the depression of a key, a previously described, the catch 71 is move forwardly until it strikes a t also Fig. 14) pivotally mermarm 78 fast on a shaft 7 9, L. arm 76 clockwise until a pin 80, carried thereby, engages a finger 81 of a latch arm 82 also pivoted at 77 to the arm 78. The pin 80 rocks the latch arm 82 clockwise until a shoulder 83 thereon is disengaged from a block cured to the side of the latch plate 7 catch 71 is provided with a shoulder 88 which hooks over a point 89 on the latch ilate 7:2 when said catch reaches the end of its forward movement (Fig. l l). A spring 90 stretched between the pin 80 and a pin 91, carried by the arm 78, holds the arms 82 {UK 76 in their normal positions.

lfVhen the catch 71 engages the trip arm 76 (Fig. 14), and rocks it clockwise, as above mentioned, the pin 80, carried by rocks the latch arm 8:2 clockw the shoulder 84:, thereby allowing the arm the shaft 79, wnicli shaft is regular key coupler to be la be rocked clockwise so tha amount keys also to be here." may be operated. After the latch arm 82 has been released from the block and when the arm 78 is rocked clockwise, as will be later de cribed, said arm 78 moves the latch arm 82 downwardly in the d its length until a toot 85 thereot pin 80 on the catch Tl rocks counter clockwise thereby disc. from the latch plate T2 to spring 06 t act to return 1 and differential drivers 39 to normal positions.

A full stroke device is also provided so that after a tax key 25, 26, or the no-sale key 27; has been slightly depressed, the operator must depress the key the full amount before said key can be ret .rned to normal position. This full stroke device includes a pawl (Figs. 1 and 8) pivotally mounted on the side of the arm 70 and held in normal position by a spring 96 stretched between a pin 97 carried by said pawl and a pin 98 carried by the arm 70. The lower end of the pawl is provided with asquare tooth 9'1: which. coope ates with a notched retaining pla e 99 mounted on the studs T5 adjacent the latch plate 72.

any one of the keys 25, 26 or 27 is and the arm 70 rocked counter se the square tooth 9-l of the pawl 95 engages the notches on the retaining plate with the notches on the retaining plate 9.9 and acts as a retaining pawl thereby making )lC to r aturn the arm 70 until said been moved counter clockwise a dis LilllCQ suthcient to cause the tootn 9d of the pawl to pass off the right-hand end (as l 1) of the retaining plate 99. also as a full stroke device g the keys to be entirely rcnial positions, after having been register any amount of tax. In -1:. as a tull stroke for the return of o. te :ey, the pawl 95 as it strikes the r1ght of the retaining plate 72 when the 70 is started in its clockwise direction, is ro ked in the reverse direction from that in which it is r .cked during a depression of the key and the square tooth 94; of said pawl cooperate with the notches in the retaining plate 99 to ii-event countor-clockwise morement of the arm 70 saio arm has started clockwise towards its normal position.

Tam totalieer The totalizer vtor accumulating t amounts oi taxes commensurate with the values of the keys depressed includes, six totaliser wheels 101 1 and 10) loose on cured to the side of the tens star wheel is a. pinion 111 2, 8 and 10) which meshes with an actuating pinion 112 (Figs. 1 and 10) which in turn meshes with the actuating segment 57. The pinion 112 is carried by a V shaped arm 118 fast on a rod 11% carried by the frames and 83.

As previously described, the actuating segments 5? and 58 are moved upwardly come inensurate with the values of the keys depressed in the tens and the units bank-s re;

spectively. The upward movement of these segments causes the actuating pinions 109 and 112, and consequently the pinions 108 and 111 to be rotated corresponding to the values of the keys depressed, thereby rotating the units and tens totalizer wheels 101 commensurate with the values of the operated keys. The means for transferring from the units to the tens totalizer wheel includes a disk 117 (Figs. 2, 3 and 10) secured to the side of the units wheel 101. Integral with the disk 117 is atransfer tooth 118 so positioned in relation to the units totalizer wheel 101 that when said wheel passes from 9 to 0 the transfer tooth 118 engages ahalf-roundpin 119 carried by a transfer arm 120 fast on a shaft 121 and rocks said transfer arm counter clockwise (Fig. 3). The transfer arm 120 carries a pin 122 which enters a cam slot 123 formed in the V-shaped lever 113. The free end of the transfer arm 120 is shaped to form an obtuse angle, normally engaged by a notch 125 of a spring pressed retaining arm to hold the transfer arm 120 in its normal position. When the tooth 118 engages he pin 119 and rocks the transfer arm 120 counter clockwise, as above described, the V-sha aed lever 113 through the pin 122 and cam slot 123 is rocked clockwise. The counter-clockwise movement of the transfer arm 120 moves the free end thereof from the notch 125 into a notch 126 in the retaining arm 124, and said transfer arm is held in this position until positively restored by means which will be hereinafter described. The clockwise rocking of the V-shaped lever 113 causes the pinion 112 to roll over the actuating segment 57, thereby turning the pinion 111 and consequently the tens totalizer wheel 101 one step, or in other words, adding one on this wheel. The transferring from the tens wheel 101 to the hundreds wheel 101 and so on through the higher order wheels 101 is accomplished by the usual Geneva star wheels 127 (Fig. 10) and gears 128 and as this Geneva transfer is old and well known in the art it will not be described herein. These transfer elements are carried by a shaft supported in the arm 103 and an arm 129 secured to the shaft 105. For a detailed description of a transfer device of this type reference may be had to Letters Patent of the United States, issued to Thomas Carney, No. 532,762, on January 22, 1895.

After the transferring from the units to the tens amount wheel has taken place the totalizer pinions 108 and 111 are lisengagcd from the actuating pinions 109 and 12.

The means for disengaging the totalizer pinions 108 and 111 from the actuating pinions 109 and 112 includes arm 130 1 and 10) integral with the totalizer sup porting arm 104. The arm 130 carries a pin 131 which projects intoa cam slot 132 formed in a totalizer engaging and disengaging lever 133 (Figs. 1, 8 and 10) fast on a shaft 134 mounted in the side frames 32 and 33. Integral with the lever 133 is an arm 135 (Fig. 4). Fast on the shaft 134 and parallel With the arm 135 is an arm 136 (Figs. 1 and 8). The arms 135 and 136 carry arod 137 which projects through slots 138 formed in the differential drivers 39.

Near the end of the clockwise movement of any one of the drivers 39, the rod 137 is moved downwardly by the slot 138 thus causing counter clockwise movement of the arms 135 and 136 and consequently of the shaft 134 and totalizer engaging and disengaging lever 133. Each of the differential drivers 39 is provided with a clearance slot 139 leading off from the slot 138 to permit downward movement of the rod 137 with respect to the drivers 39 not rocked from normal. position. This counter clockwise movement of the lever 133, through the cam slot 132 therein and the pin 131 causes a counter clockwise rocking of the arm 130 and consequently of the arms 103 and 104, thereby disengaging the totalizer ainions 108 and 111 from the actuating pinions 109 and 112 respectively.

During the disengaging of the totalizer pinions 108 and 111 from their actuating pinions 109 and 112 respectively the transfer mechanism previously described is restored to normal position. The means for acconn lishing this includes a transfer restoring arm 140 (Figs. 1, 2 and 3), fast on the shaft 121. The arm 140 carries a stud 141 which cooperates with a toe 142 integral with the totalizer supporting arm 104.

It will be remembered from the previous description that when the transfer takes place, the transfer arm 120 and consequently the shaft 121 are rocked counter clockwise (Fig. 3), this causing the transfer restoring arm 140 to be rocked likewise. When the totalizer supporting arm 104 is rocked counter clockwise, as above described to disengage the tax totalizer from the actuating pinions 109 and 112, the toe 142 of the arm 104- strikcs the stud 141 and rocks the transfer restoring arm 140, the shaft 121 and consequently the trans fer arm 120 clockwise to normal positions. This movement, however, does not happen until after the totalizer pinion 111 has been disengaged from the actuating pinion 112, and therefore the amount which was transferred to this pinion 111 and its totalizer wheel 101 will remain thereon. The restoring of the transfer arm 120 to normal position, through the pin 122 and cam slot 123, r cks the Vshaped lever 113 counter clockwise to normal position ready to receive the next transfer operation when the units Wheel passes from to 0. The restoring of the transfer arm 120 removes its free end from the notch 126 to the notch 125 in the arm 124, and said arm 120 is thereby held in its normal position.

Means is provided for aligning the units I star wheels 106 of the units and. tens to whe ls and are in such relation theretosaid star wheels engage the lower ends of t pawls 1 before the pinions 108 and 111 are entirely disengaged from the pinions 109 and 112, thereby insuring positive alignment of the totalizer wheels when they become fully disengaged to allow restoring of the tripped transfer device.

One of the pawls 1415 is normally held against a collar 1 1-7 mounted eccer rically on a stud 148 carried by the side frame The collar 1417 may be turned on the stud to adjust the pawls 1415 in the exact proper relations to the star wheels 106 and after adjustment said collar it may be locked in position by means of a screw 149.

The means for aligning the totalizer engagii'i'g and disengaging lever 133 includes two notches 151 and 152 formed in the upper end thereof. I The notch 151 is normally engaged by a pawl 153 loose on the shaft 105, said pawl is held by a spring 15 1 stretched between the forward end of the pawl 153 and a stud 155, carried by the side frame 33. \Vlie the lever 133 is rocked counter clockwise to disengage the totalizer, the pawl 153 is disengaged from the notch 151'and enters the notch 152, thereby holding said lever and the totalizer in alignment until it is again engaged with its actuating pinions.

When the no taX' key 27 is depressed, its corresponding driver 39 is rocked clockwise but as the slot 14 therein is on a true are about the center of the rod 19, as previously descrihed, the lever and the actuating seg ment 57 will not be moved, therefore not. will be i dded upon the totalizer when the no tax key is depressed.

Tam indication tax commensurate with the value of an o The means for indicating the amou t o 163, has two double flanges 165 (Figs.

"cooperating with the guides 161 to stabilize the targets as they are raised and lowered. The lower end of each indicator target has a pair of loops 166 to support the targets on the upper ends of links 167 connected to indicator lifting arms 169 by pivot pins 168. The indicator lifting arms 169 are pivoted on the rod 10 between the differential drivers 39 and the guides 11. The indicator target box 162 is secured to a yoke 170 (Figs. 4 and 8) integral with parallel arms 171 fast to side frames 32 and The means for raising the proper target into view when a key is depressed includes an indicator operating arm 175 (Fig. 1) integral with the differential driver 39. The arm 175 carries a pin 176 upon which the indicator lifting arm 169 normally rests. From this description it will be seen that when any one of the keys is depressed and the corresponding differential driver 39 is rocked clockwise, as previously described, the indicator operating arm 175 through the pin 176, raises the associated indicator lifting arm 169, link 167, and target 160 so that the characters thereon will be exposed to view above the target box 162.

The means for holding the target in view .tcr it has been raised includes a latch arm igs. 1 and 9) integral with the indig' arm 169. Held in engagement back of the latch arm 177 by means or a spring 178 is a retaining bail 179 carried by parallel arms 180 loose on a rod 181 carried by the side frames 32 and 33. When the indicator lifting arm 169 and arm 177 are raised to expose the indicator target to view, the retaining bail 179, engages underneath a shoulder 182 formed on the retaining arm 177 and holds the indicator target in view until released by the depression of a key in a subsequent operation of the machine.

Means is provided for concealing the target until is has been raised to its proper height. This means includes a flash 1'85 (Figs. 1, 1 and 9) which surrounds the target box 162. Connected to the flash 185 by pin and slot connection are two parallel flash-operating arms 186 fast upon a shaft 187 mounted in the side frames 32 and 33. Integral with the right hand arm 186 (as viewed in Figs. 4 and 8) is a segment 188 which meshes with his description it can be readily seen, when the lever 63 is rocked counter clockwise 1), as previously described, that through the segments 188 and 189, the shaft 187 and the flash-operating arms 186, will be rocked clockwise to raise the flash 185 simultaneously with the raising of the indicator target, it being remembered that the raising of the target and the rocking of the arm are both caused by the depression of any of the keys 25, 26 or 27. Upon release of the key and its restoration to normal position, the lever 63 is rocked clockwise to nor mal position, and therefore the flash-operating arms 186 will be rocked counter clockwise, to lower the flash 185 to its normal home position while the lifted target remains exposed to public view.

In a subsequent operation of the machine a cam edge 190 on the latch arm 177 rocks the retaining bail 179 and the arms 180 counter clockwise thereby releasing the previously raised indicator target and allowing it to return to normal position.

Amount registering mechanism The mechanism for registering and indieating the amount of the sale after the tax has been registered by the means previously described, will be only briefly described here, as this mechanism is substantially the same as that fully illustrated and described in the above mentioned Carney Patent, No. 497,860, and Cleal Patent, No. 718,565, and reference to these patents may be had for a more minute description of these mechanisms. Described briefly, those mechanisms, as substantially illustrated here, include a series of amount keys 195 (Figs. 4 and 12), pivotally mounted upon a rod 196 carried by side frames 197 and 198. Common to all of the keys 195 is a key coupler 199 (Figs. 4 and 12) pivotally mounted at its right hand end in the frame 198, by means of a trunnion 191 (Figs. 4 and 11), its left hand end being fast upon the shaft 79 (Fig. l), previously described, mounted in the side frame 33 and the frame 197. Each of the pivoted keys 195 is provided with a notch 200 adapted to cooperate with a lip 201 formed on the rear edge of the key coupler 199 when any of the pivoted keys is depressed at its outer end. Suitably mounted in the side frames 197 and 198 is a transverse rotation shaft 202 (Figs. 11 and, 12) given a complete rotation upon each oscillation of the key coupler 199 by a mechanism shown in Fig. 11. By referring to said figure, it will be noted that at its right hand end the key coupler 199 is provided with a stud 203 which projects into an elongated slot 204 formed in a vertically reciprocable double rack 205. At its lower end the double rack 205 is provided with an open slot 206 receiving a stud 194 mounted on the right hand side frame 198. At its upper end the rack 206 is also slotted, and on the side walls of the slot, the rack 205 is provided with oppositely faced rack teeth 207.which cooper ate with a pinion 208 fast on the rotation shaft 202. This mechanism is of substantially the same construction and operation as the mechanism shown in the aforesaid Carney Patent, No. 497,860, and Cleal Patent,

to the right hand end of the shaft 202 and cooperates with a full stroke pawl or lever 210 pivoted at 211 to the right side frame 198 of the machine, and held in engagement with the ratchet 209 by means of a spring 212 seated in a block 213 on the right hand side frame 198.

It will thus be seen that upon each complete depression and return of the pivoted key levers, the key coupler 199 will be oscillated and through the connections shown in Fig. 11 and just described, a single rotation will be given to the shaft 202. The function of the key coupler 199, as is well known in the art, is to permit the starting of an operation of two or more keys, for example, the $1.00 key and the key, and then the completion of the operation by pressing eitoer one of those keys. By reason of the engagement of the lip 201 of the key coupler 199 with the notches 200 in the keys, the $1.00 key and the 70 key will be fully operated by the complete depression of either one of the two.

From the mechanism just described, it can be seen that it is necessary to oscillate the key coupler 199, and from the mechanism previously described in connection with the tax keys 25 and 26 it can also be seen that before the key coupler 199 can be oscillated, it must of necessity be free to oscillate. In other words the latch arm 82, Figs. 13 and 1 1, which it will be remembered is connected to the arm 78 fast on the key coupler shaft 79, must be released from the block 84L in order to allow the arm 78, the shaft 79 and the key coupler 199 to be rocked. The releasing of this latch arm 82 from the block 8%, as has been previously described, is caused by the depression of one of the keys 25 or 26 in either of the two banks representing the taxable amounts. After a key in either one of the tax banks has been depressed, and released the latch arm 82, any of the keys 195 (Fig. 4) may be depressed to register the amount of the sale upon a purchase totalizer, to be hereinafter described.

It will also be remembered that when one of the tax keys is depressed, the catch 71, as it rocks the trip arm 7 6 to disengage the latch arm 82 from the block 8 1, hooks over the point 89 of the plate 72. This construction makes its necessary for the operator to depress one of the keys 195 to register the amount of sale into purchase iTOttlllZQl after.

one of the tax keys 25 or 26 has been depressed to register the tax of a sale into the tax totalizer to compl te the registration before another tax key can be depressed. The depression of one of the keys 195, it will be ren'iembered, raises the key coupler 199 and pon release of the key 195 the key coupler 199 rocks clockwise (Figs. 11 and 12) and causes the shaft 79 to be rocked counter clockand 216 12) just above the e in the previous operation.

The indicator bars 21'? are yielding-1y held in their lowermost positions by springs 219 so that the lower ends of said bars cont-act t 1e rear ends of the pr. oted :eys 195. Each of the indicators 21S bears a special character or characters which are preferably identical with the char appearing on the forward ends o't t appropriate pivoted keys.

Operation For convenience in describing the operation of the machine, let it be assumed that the merchant has a taxable sale of 90 to register. On a ten percent basis, the tax on this amount would be 99%.

To register this amount, the merchant first depresses the 9 tax key 26 in the units bank (Fig. 4:) thereby rocking its appropriate dif ferential driver 39 (Fig. 1) clockwise and the slot 4:4? in this driver will move the rod 52 (Fig. 8) downwardly, thereby moving the actuating segment 58 upwardly a distance commensurate with the value of the 9 key, the upward movement of the segment causing a rotation of the actuating pinion 109 (F ig. 10) and totalizer pinion 108 a distance of nine spaces, whereby 9 will be registered upon the units wheel 101 of the tax totalizer. During the clockwise movement of the differential driver 39, the pin 176 rocks the associated indicator lifting arm 169, (Figs. 1 and 13) and its corresponding link 167 is raised and exposes the 9 indicator target 160 to view. After the target has been lifted, the spring 178 rocks the retaining bail 179 beneath the shoulder 182 of the latch arm 177, and holds the target exposed until it is released by a subsequent operation of the machine. During the raising of the target, it is concealed from view by means of the flash185 which, it will be remembered, is raised by the flash-operating arms 186 through the operation of the segments 188 and 189 which in turn are rocked by the slot 60 in the arm 59 integral with the differential driver 39. The slot 60, it will be remembered, also causes a counter clockwise movement of the arm 70, whereby the catch 71 strikes and rocks the trip arm 76 which rocks the latch arm 82 clockwise releasing its shoulder 83 from the block 84. The catch 71 finally hooks over the point 89 of the latch plate 72 and remains in this position. Near the end of the clockwise movement of the dif-' ferential driver 39, through the slot 138 therein and rod 137, the totalizer engaging and disengaging lever 133 is rocked counter clockwise to disengage the totalizer pinions 108 and 111 from the actuating pinions 109 and 112.

After the merchant has made a complete depression of the 9 key causing the elements to be operated as just described, he then depresses the 90 key 195 (Fig. 4) to register the amount of the sale. The depression of this key rocks the key coupler 199 counter clockwise, causes the 90 indicator 218 to be exposed to view, and rocks the seg ment 236 to accumulate the amount of sale on the totalizer wheels 228. The shaft 202 is also given a complete rotation thereby rocking the totalizer frame 232 so that the totaliZer elements will be engaged with their actuating segments 236 and disengaged therefrom after the amount has been accumulated thereon. The depression of the 90 key and the consequent rocking of the key coupler 199 rocks the shaft 79 clockwise (Figs. 1 and 13) thereby rocking the arm 78 clockwise and moving the latch arm 82 downwardly in the direction of its length a distance suflicient to cause its foot 85 to ei'igage the pin 86 on the catch 71 and rock said catch counter clock- Wise, and thereby disengage its shoulder 88 from the point 89 on the latch plate 72. Upon release of this catch 71, the restoring spring 66, having been put under extra tension, acts and rocks the lever 63, the shaft 64;, the arm 62 and the arm 70 clockwise to their normal positions. The movement of the arm 62 through the rod 61 rocks the arms 59 and consequently the differential driver 39 counter clockwise to normal positions. During the last part of the counter clockwise movement of the driver 39 the totalizer engaging and disengaging lever 133 is rocked clockwise to normal position, thereby engaging the tax totalizer with its actuating elements. The flash plate 185 is also lowered by the rocking of the lever 63, through the segments 188 and 189. The 9 indicator target 160 of the amount of the tax and the 90 indicator 218 of the amount of the sale will remain exposed to view until a subsequent operation of the machine, when they will be lowered to normal positions and new indicator targets raised dependent upon the keys depressed.

Should the sale not involve tax the no tax key 27 is depressed in place of one of the tax keys 25 or 26 and the mechanism is operated in substantially the same manner as when one of the keys 25 or 26 is depressed, except that no amount will be accumulated upon the tax totalizer. However, it is necessary to depress this no tax key in order to unlock the key coupler 199 so that one of the keys 195 may be depressed to register the ordinary amount of the sale involving no tax and therefore the no tax target will be exposed to View showing that the merchant sold a non-taxable article.
