In general The machine to which the present invention is shown applied in its preferred form, includes a plurality of totalizers, one for accumulating each classification of transactions and one for accumulating each individual transaction. These totalizers are operated by differential mechanism under control of de pressible keys. The differential mechanism provides means for adjusting type elements (not shown) to print on the issuing receipt the amounts entered in the totalizers, together with the total of the same, and also to print on the record strip, which is retained in the machine, transaction and classification totals.

Printing and indicating mechanisms are present invention, they are neither shown or described herein.

The machine is provided with a plurality of clerks keys and special counters therefor (not shown), to set up type and control the 5 ness where it is desired to issue an itemized printed receipt to the customer and reta n in the machine a record strip containing not only the totals of each itemized receipt issued, but also the amounts of each single-item transaction.

Operating mechanism The machine is manually operated by a handle 50 (Fig. 1), mounted on a stud 51. Connected to the handle 50 is a pinion 52 meshing with a gear 53 mounted on a stud 54 projecting from the frame of the machine. The gear 53 meshes with a gear 55 secured on the main drive shaft 56. The ratio of the pinion 52 and the gear 55 is such that two rotations of the handle will cause one rotation of a main drive shaft 56.

The machine may also be operated by an electric motor. Only a part of the motor clutch mechanism is shown in the accompanying drawings. The motor is mounted on the left hand side frame of the machine. The clutch mechanism between the motor and the machine includes a spring actuated disk 57 (Fig. 10) mounted upon a stud 58. This disk carries a. lug 59, which normally contacts the forward end 60 of an arm 61 pivoted on a stud 62 on the frame of the, machine. An arm 63 secured to the arm 61 carries a pin 64 which normally rests on the curved edge 65 of an arm 66 pivoted on a printer drive shaft 67 'ournaled in the printer frame. The arm 66 is connected by alink 68 to an arm 69 secured to a shaft 70 extending across the entire machine and journaled in the frames thereof. 'hen the shaft 70 is rocked clockwise to relcase the machine, as will hereinafter be described, the arm 66 is rocked clockwise from beneath the pin 64, permitting the spring 75, attached to the arm 63 and to a pin 76 projecting from the frame of the machine, to move the end 60 of the arm '61 away from the lug 59. The clockwisemovement of the lever is limited by a pin 77 projecting from the frame of the machine. Upon release of the arm 61 the disk 57 is moved clockwise bv a spring (not shown), effecting an operative connection between the motor and the driving clutch to operate the machine.

The main drive shaft 56 is driven from a gear 78 secured to one of the driving clutch members (not shown). This gear meshes with a gear 79 freely mounted on a stud 80 supported in the side frame of the machine. Pinned to the gear 79 is a gear 81 which meshes with a gear 82 secured to the ma n drive shaft 56. The gear 81 also meshes with a gear 83 secured to the printer drive shaft 67. The main drive shaft 56 and the printer drive shaft 67 are given one complete rotation during an adding operation of the machine. The arm 61 is restorcd to its locking position near the end of the o eration of the machine by means of a disk 84 Fig. 9) pinned to the shaft 67. This disk carries a pin 85, which engages a curved edge 86 of the arm 63 to restore the arm 61 to stop the machine. This permits the return of the arm 66 and consequently the shaft 70 to their normal positions. Keg board The keyboard comprises one bank of clerks keys 96, a bank of transaction keys 30 and 32 (Fig. 4), a starting bar 33 (Fig. 1), a total lever 34 (Fig. 7) for controlling the machine for total and sub-total operations, and a plurality of banks of amount keys (not shown). A key 31 located in the transaction bank is provided to manually release any of the keys in this bank.

The banks of amount keys are not shown or described herein as they form no part of the present invention. Reference for a description of the same can be made to the copending application referred to, of which this is a division.

The machine is normally released for operation by depression of a clerks key 96 (Fig. 6), a transaction key 30 or 32 (Fig. 4), and the starting bar 33 (Fig. 1), which releases the shaft 70.

The starting bar 33 is detachably mounted upon a slide 100, supported by two studs 101 engaging elongated openings 102 in the slide 100. These studs are mounted on the frame of the machine. The bar is retained in its normal outer position by a spring 103. The slide carries a pin 104 embraced by a forked arm 105 pivoted on the stud 51 and connected by a link 106 to one arm of a bell crank lever 107 pivoted on a rod 108 supported in the frame of the machine. The other arm 109 of the lever lies in the path of a half-round stud 110, carried by arm 111 pinned to the shaft 70, to compel depression of the bar 33 to release the machine. Depression of the starting bar moves the arm 109 out of the path of the stud 110, thereby permitting the shaft to be rocked to release the clutch mechanism previously described.

When the shaft 70 is rocked to release the motor clutch, the stud moves under the arm 109, thus holding the starting bar 33 depressed. Near the end of the operation of the machine, the shaft 70 moves back to, and past its home position, and, consequently the stud 110 moves out from under the arm 109 and past the end of a non-repeat awl 118 pivoted on the rod 108. Removal of the stud 110 from beneath the arm 109 permits the spring 103 to return the starting bar 33 to its normal released position.

The non-repeat pawl 118 is provided to prevent repeat operations it the starting bar should be held depressed during the entire operation ofthe machine. This pawl is normally held against an off-set portion of the arm 109 by a spring (not shown), but when thestarting bar 33 is depressed, the arm 109 is elevated out of contact with the non-repeat pawl 118. and the stud 110 prevents the pawl from following the arm 109. If the starting bar 33 is held depressed during the entire operation of the machine, thus holding the arm 109 elevated, then near the end of the operation of the machine, when the shaft 70, arm 111 and stud 110 are moved back past their home positons and past the end of the non-repeat pawl 118, the spring (not shown) connected to the pawl and a pin on the machine frame, will rock the pawl counterclockwise until it contacts the elevated arm 109, thus locking the machine against another operation. In this position, the end of the non-repeat pawl 118 is in the path of the stud 110, consequently the machine cannot be releascd. even though the starting bar 33 is held depressed and the arm 109 remains elevated. l hen pressure is removed from the bar 33 the spring 103 restores the bar 33 and the arm 109 to normal position, and the non-repeat pawl 118 is returned to normal position by the arm 109.

The shaft 79 is moved by an arm 121 secured to the shaft outside of the right end frame of the machine. This arm carries a screw stud 122 supporting the spring retaining pilots 123, placed on the opposlte sides of a link 124, slotted at 126 to move over the stud. A coiled spring 125 surrounding the lower ends of the pilots 123, is compressed between the shoulders on said pilots the lower end of the slot 126 in the link 124. From this it can be seen that, as the starting bar is depressed and the arm 109'is moved counter-clockwise, the spring 125 is released to rock the shaft 70 clockwise to release the motor clutch mechanism previously described.

Transaction keys The transaction keys are divided into two groups arranged in a single bank and mounted in a common frame 129 (Fig. 4) supported by rods 93. The keys 30 of the upper group are used in registering multiple-item transactions. The keys 32 of the lower group are used in registering single-item transactions.

The keys are held in their normal positions by springs not shown and are retained in depressed positions by a spring urged locking detent 131 engaging pins 130 on the keys. The detent 131 is mounted on arms 132 and The key pins 130 also wipe against beveled edges 128 and 143 of recesses formed in a settingbar 136 (Figs. 2, 3 and to'shift the 3 bar and operate interlocking mechanism between the transaction keys and the starting bar 33. The settin bar 136 is supported by arms 137 and 138. Mounted in the arm 137 is a pin 139, which engages an upwardly extending arm 140 of a yoke 141, pivoted on the rod 108. As a transaction key is depressed, the pin 130 will engage the inclined edge 128 or 143 (Figs. 3 and 5) on the setting bar 136 and move the detent bar toward the left to rock the yoke 141 counter-clockwise. The arm 140 is maintained in engagement with the pin 139 by a spring 144. As the yoke 141 moves counter-clockwise, it carries with it a retaining arm 145 pivoted on the rod 108 and held in contact with the upper edge of the yoke 141 by a spring 146. This retaining arm has a pro ection 147 whichnormally lies in the path of a flattened stud 148 mounted in an arm 149 pinned to the shaft 70. An interlock is thereby formed between the transaction keys and the starting bar 33 so that if the starting bar is operated without depressing a transaction key, the machine will not be released for operation. If the transaction key is depressed in its proper sequence, the projection 147 will be out of the path of the stud 148 when the starting bar is operated.

The transaction keys are not restored to normal positions during the operation of the machine, as are the amount keys, and in some cases, the clerks keys, but remain in depressed positions until released by depression of another transaction key, or the release key 31 (Fig. 4). This release key has a pin 159, normally adjacent the angle side of a projection 160 on the detent 131 to move this detent to the left to release any depressed transaction key. Depression of the release key does not affect the setting bar 136, as this bar has a recess opposite the pin 159 as shown in Fig. 3.

In entering a multiple item transaction, the operated key should be locked in depressed position, and all other transaction keys locked against depression, until the completion of the entire transaction.

This result may be conveniently obtained by arranging the inclined walls of those recesses in the setting bar 136 which lie beneath the multiple item keys 30, so that upon depression of a multiple item key 30, the setting bar 136 is given a greater extent of movement than is imparted to it by the single item key 32, and by providing the arm 138, to which the lower end of the setting bar 136 is pivoted, with a notch 154 (Figs. 2 and 3) engageable by a locking bail 153 journaled on a shaft 152.

When a single item key 32 is depressed, the setting bar 136 is not shifted a suilicient distance to swing the notched arm 138 far enough to bring the notch 154 into the path of the locking bail 153. But, owing to the longer incline of the edges 143 of the recesses in the setting bar 136 beneath the multiple key will shift the setting item keys 30, depression of a multiple item bar 136 and its arm 138 to such an extent that, upon complete depression of the key and the restoration of the detent- 131 and its arm 133 to locking position, the notch 154 in the arm'138 is located in the path of the locking bail 153, preparatory to the entry of the edge of the locking bail 153 thereinto.

An arm 151, pivoted on the shaft 152, is secured to the lock hail 153 to control the latter. The inner free end of the bail arm 151 extends inwardly into the path of a stud 155 projecting from the usual differentially mov' able arm 275, which normally maintains the bail arm 151 and the locking bail 153 in idle position against the tension of a spring connected with the arm 151, which tends to rock the arm 151 and locking bail 153 counterclockwise toward the arm 138.

On a multiple item operation, a multiple item key, and the amount keys are depressed,

and an operation of the machine rocks the differential arm 275 clockwise, in a well known manner, to select the proper totalizer, and in so doing, the differential arm 275 releases the bail arm 151 to the action of a spring, which rocks the arm 151 and its looking bail 153 counter-clockwise, to enter the bail 153 in the notch 154 andhold the depressed multiple item key 30 in its depressed position (as shown in Fig. 3), throughout two or more operations of the machine.

The extended travel permitted the look ing bail 153 when it enters the notch 154,

positions the bail beneath the arm 133 to thereby look all other keys in the transaction bank against depression.

- When a single item key 32 is depressed, and the machine is operated, the limited travel permitted the locking bail 153 is such that the free end of the bail arm 151 remains in the path of the stud 155, when the bail contacts the unnotched end of the arm 138 (as shown in Fig. 2), so that upon the return of the differential arm 275, at the end of the operation, the stud contacts the. bail arm 151 and restores it, together with the bail 153, to idle position (as shown in Fin. 4). But. when a multiple item key 30 is depressed, and the machine is operated, the extent. of travel of the bail 153 withdraws the free end of the arm 151 from the path of the stud 155 on the differential arm 275 (Fig. 3) as above described.

Therefore, to effect the release of the depressed multiple item key 30, and the restoration of the locking bail 153 to its idle position, the usual total lever 34 (Fig. 7) is provided with a cam slot 190. After all the items of a multiple item transaction have been entered in the machine, the total lever 34 is manually shifted from its normal add position to the item total position,

and after the total is printed, the total lever is restored to its normal add position. A roller 189 carried on one arm of the intermediate lever 191, pivoted at 192, enters the cam slot 190 in the total lever. The opposite arm 193 of the lever 19]. has formed on one edge thereof a cam recess 187. A link 194, also pivoted at 192, and overlying the arm 193 of the lever 191, has a complementary cam recess 188 formed in its edge, which coop crates with the cam recess formed in the arm 193 of the lever 191 to constitute a cam sl t. A spring 199 connects a stud 198 on the link 194 with the arm 193 of the lever 191 to hold these parts together, with the stud 19 in con tact with the upper end of the arm 193. This arrangement provides a flexible cam mecha nism which will yield to prevent injury to the machine in case the shaft 152 is locked by a depressed key, at the time the total lever 34 is shifted from its add position. A crank 190 fast on the shaft 152, on which the bail carrying arm 151 is pivoted, carries a roller 195 entered in the cam slot formed by the complementary edges 187 and 188 of the arm 193 and the link 194 respectively.

When the total lever 34 is adjusted from its add position to its item total position, its cam slot 190 rocks the lever 191 in a counter-clockwise direction, and the arm 193 of the lever 191 together with the link 194, rocks the crank 196 and the shaft 152 in a clockwise direction.

A tappet 150 (Fig. 4), fast on the shaft 152, is thereby rocked to contact a stud on the bail arm 151.

As is customary in machines of the type to which this invention is applied, a total taking operation includes two cycles of rotation of the main drive shaft 56 of the machine, during the latter part of the first of which cycles, the shaft 152 is rotated slightlv farther in a clockwise direction (by means later described) which presses the tappet 150 against the stud on the bail arm 151 to rock the bail arm 151 clockwise sufiiciently to return the free end of the bail arm into the path of the stud 155 on the differential arm 275, when the latter is at a point some distance above the bail arm 151, so that as the differential arm 275 is restored, its stud strikes the free end of the bail arm 151 and withdraws the locking bail 158 from the notch 154 in the arm 138 to permit the release of the depressed multiple item key 30.

Near the end of the operation of the ma chine, the parts operated by the depression of the starting bar 33 are restored to their normal positions by a cam 200 (Fig. 1) formed in the side of the gear Cooperating with this cam is a roller 201 on an arm 202 pivotally mounted on a stud 203 projecting from the side frame. The upper end of the arm 202 carries a pin 204 which normally engages aslot 205 formed in the link 124.

As the gear 53 rotates, the arm is moved first clockwise and then counter-clockwise, which causes the link 124 to move downwardly and then return. During the operation of the machine, the headed stud 122 is in contact with the upper end of the slot 126, and the shaft is rocked counter-clockwise, which permits the arm 109 (Fig. 1) and the retaining arm 145 (Fig. 4) to return to their normal positions, at the same time allowing all of the parts cooperating therewith to return to their normal positions.

Clerks keys Four clerks keys 96 (Fig. 6) are provided. These keys are located near the left hand side of the machine and are mounted in a key frame 95 supported by the rod 93 and a rod 94. The keys 96 when depressed are so retained by a detent 164 which is moved toward the right when one of the keys is depressed. The detent- 164 is spring urged toward the left and after the key has been depressed, the shoulder 165 engages a pin 97 mounted in the shank of the key. The detent is slidably mounted on headed studs 166. The depressed clerks key is returned to normal by a spring (not shown) near the end of a single-item operation and near the end of the second cycle of a total-taking operation. The detent 164 is moved to release the keys by a bell crank, one arm 168 of which constitutes a cam adapted to engage a pin 169 on the detent 164 to move the latter to release any depressed clerks key. The bell crank is pivoted on a stud 170 and is held in its normal position by a spring 171. The other arm 172 of the bell crank is adapted to be engaged by a pin 173 carried on a segment gear 17 4 pivoted upon the sleeve 163. As the segment gear moves clockwise, the pin 173 strikes the arm 172 and moves it in a counter-clockwise direction. As the pin 173 passes off the arm, the bell crank will be returned to its normal position by the spring 171. When the segment gear 174 is moved counter-clockwise to its normal position, the pin 173 will strike the rear side of the arm 172 of the bell crank, thereby rocking the cam arm 168 clockwise to engage the pin 169, thus moving the detent 164 to the right. This movement of the detent disengages the shoulder 165 from the pin 97, permitting the depressed key to be returned to its normal position. When the pin 173 passes off the arm 172, the spring 171 again returns said arm to its normal position.

Mechanism is provided to compel the depression of a clerks key before the machine can be released for operation. Pinned to the shaft 70 is an arm 180 (Fig. 6) normally contacting the under side of a pin 181 carried by a releasing slide 182 slidably mounted on screw studs 166 and retained in its nor mal position by a spring 183. As a clerks key is depressed, the pin 97 will engage an inclined edge 184 of the releasing slide 182 and move the slide toward the left to remove the pin 181 from the arm 180. The shaft 70 is then free to be rockcd, as hereinbcfore described, to release the machine for operation.

The segment 17 4 has a rearwardly extending arm 210 (Figs. 6 and 7), connected by a link 211 (Fig. 8) to a lever 212 pivoted on the stud 213 projecting from the printer frame (not shown). The lever 212 has a downwardly extending arm 214 to which is attached a spring 215. This spring is normally under tension, and when released by movement of a link 220 to the right (Fig. 10) will, through the lever 212 and link 211, impart to the gear segment 174 its clockwise movement. The clockwise movement of the lever 212 and consequently the clockwise movement of the segment 17 4 is limited by a stud 216 in the path of an arm 217 on the lever 212.

The counter-clockwise movement of the segment 174 is accomplished as follows: The link 220, (Fig. 10) near its left hand end, is guided by a pin 221 projecting from the printer frame 209. At its right hand end the link 220 is pivoted to a lever 222. This lever is pivoted on a stud 223 and is given a movement first clockwise and then counterclockwise by a pair of cams 224, (Fig. 11), secured to the shaft 67 and cooperating with rollers 226, carried by the lever 222. The forward end of the link 220 engages the pin 173 on the segment 174 to normally maintain the segment 17 4 in position, and when the link 220 moves to the right, the segment 17 4 is released to the action of its spring 215. The end of the link 220 also controls the stud 173 to return the segment 174 to its normal position upon return movement of the link 220 toward the left.

The. gear teeth on the segment 17 4 are not used in the present invention, but it is though that a brief description of their use, as illustrated and described in the above mentioned co-pending application, will be helpful. This segment is adapted to receive a long and a short oscillation to impart to the issuing receipt a long feed and a short feed. The length of the feed is governed by the character of the transaction. The movement of the feeding mechanism on 'a single-item transaction is equal to the greater movement of the segment 17 4. When an item of a multiple-item transaction is entered, the feeding mechanism will move a distance equal to the shorter movement of the segment 174.

It is therefore to be understood that when an individual item of a multiple-item transaction is entered in the machine, it is not desired that the clerks key should be released.

A description of the mechanism for controlling the release of the clerks key will now be given.

Pivoted on a shaft 230 is an arm 231 (Figs.

8, 10, 12 and 13) which is operated by a flexible drive mechanism on account of the overlapping of time in the operation of the segment 174 and the arm 231. Projecting laterally from-the arm 231 is a pin 232 rojectin between two arms 233 and 234 ig. 8) held in contact with the pin b aspring 235 stretched between the arms. hese arms are driven by a pin 236 carried by a lever 237, pinned to the shaft 230. When the arm 231 IS moved counter-clockwise to the position shown in Fig. 12, the hook ortion of the arm will be in the path of a attened stud 238, carried by the segement 174. With the arm 231 in this position, the segment 174 will be limited to its shorter movement. The arm 231 is placed in this position by mechanism controlled from the transaction keys. Secured to the segment lever 240 (Fig. 10) is a cam arm 241 (Figs. 12 and 13) the outer edge 245 of which contacts a roller 242 carried by an arm 243 loose on the shaft 230 (Figs. 10, 12 and 13) This cam arm 241 has an inn-er edge 244 in addition to its outer edge 245. n single-item transactions the outer edge 245 of the cam arm is in contact with the roller 242, with the arm 231 in its ineffective position in relation to the flattened stud 238. With the arm 231 in this position, the depressed clerks key will be released on each single'item transaction operation. In a multiple-item transaction operation the cam arm 241 is given a counterclockwise movement, sufiicient to bring the inner edge 244 of the cam arm 241 opposite the roller, whereupon a spring 246, stretched between an arm 247 pinned to the shaft 230 and a pin projecting from the printer frame, will rock the arm 231 counter-clockwise into the path of the flattened stud 238. In this position the arm 231 will limit the clockwise movement of the segment 174. This limited movement of the segment is not sufiicient to carry the pin 173 past the arm 172, for which reason the cam arm 168 will not receive a clockwise movement, and the clerks key will not be released when the items of a multipleitem transaction are entered.

After the last item of a multiple-item transaction has been entered, the totalizing lever 34 (Fig. 7) is moved to the item total position, which lmparts an initial movement to the shaft 152 scribed.

In machines of the type to which the present invention is shown applied, two cycles of operation are performed by the machine when taking totals. During a multiple-item total taking operation, the cam arm 241 remains in the position to which it is moved during the multiple-item entry operation. However, when the total lever 34 is shifted to the itemtotal position the arm 231 is shifted to the position shown in Fig. 13. During the first cycle the cams 224 (Fig. 11) rock the lever 222 cam arm 168 is not moved, and

(Figs. 12 and 13) as previously declockwise which moves the link 220 to the right, as previously stated, whereupon the s ring 215 (Fig. 8) rocks the segment 174 c ockwise. Near the end of such first cycle of operation the link 220 is returned to normal and moves the segment 174 to its normal position to feed the receipt :1 short distance to space the total from the last printed item, as is fully disclosed in the parent application above mentioned. But, as the pin 173 did not pass to the right of the arm 172, due to the short movement of the segment 174, the the clerks key remains depressed at the end of the first cycle of 0 ration of an item-total operation. The mecli nism which shifts the arm 231 to the position shown in Fig. 13 is as follows:

Secured to the shaft 152 is an arm 250 (Figs. 10, 12 and 13) connected to one end of a pitman 251, which at its opposite end is bi urcated to slide on the shaft 230. The pitman 251 carries a roller 252, which engages an arm 253 pinned to the shaft 230. The ini tial, clockwise movement of the shaft 152 will, through the means just described, rock the arm 253, shaft 230 and arm 231 clockwise to the position shown in Fig. 13, thus leaving the 00k arm 231 above the stud 238 so that the segment 174 is limited to a short movement, and consequently, the depressed clerks key will not be released during the first cycle, as above mentioned.

Near the end of the first cycle of operation the shaft 152 is given an additional movement, hereinafter described, to move the pitman 251 farther toward the right (Fig. 10), and in so doing the roller 252 earns the arm 253 farther clockwise to move the hook of the arm 231 out of the path of the stud 238, to permit the segment 174 to receive its full extent of movement under the influence of the spring 215, during the second cycle of the operation. During such second cycle, and before the segment 174 can be moved its full extent as just stated, the cams 224 move the link 220 to the right to permit the spring 215 to function as above stated. Now, this full extent of movement of the segment 174 moves the stud 173 to the right of the bell crank arm 172, so that when the segment 174 is returned to its normal position by the link 220, the bell crank 172 is rocked by the stud 173, whereupon the cam arm 168, by its contact with the Stud 169 (Fig. 6), cams the detent 164 to the ri ht to release the depressed clerks key.

when taking totals from classification totalizers, other than the multiple-item totalizers, one of the single-item keys is depressed to select a totalizer, and therefore, the cam arm 241, under control would be shifted to such a position as to move the outer edge 245 of the cam arm beneath the roller 242, (Fig. 10), which would move the arm 231 out of the path of the stud 238, and then the segment 174 would receive two full of a single-item key,

extents of movement, one during each cycle of operation, which would result in the receipt getting two'long feeds, and the clerks key would be released during the first cycle of such a total taking operation. I

To avoid such a release of the clerks key, during the first cycle, a mechanism to move the roller 242 out of the path of the outer edge 245 of the cam arm 241 before such total taking operation, without moving the arm 231, is provided, and is controlled by the manual movement of the total lever 34.

As above mentioned, the shaft 152 is given an initial movement when the total lever is shifted to any total taking position, but as the initial movement of the shaft 152 is not sufficient to move the roller 242 out of the path of the outer edge 245 of the cam arm 241, an arm 254 is pinned to the shaft 152 and connected to one end of the link 255 which, at its opposite end, carries a roller 256 engaging a slot 257 in the arm 243 loose on the shaft 230, and a slot 258 in the arm 247 pinned to the shaft 230. As the shaft 152 is given its initial movement, the roller 256 moves downwardly in the slots 257 and 258 (Fig. 10), causing the arm 243 to move clockwise to a position in which the roller 242 is clear of the cam arm 241 (Fig. 13). When the shaft 152 receives an additional movement, hereinafter to be described, the roller 256 continues its downward movement in the slots 257 and 258 without imparting additional movement to the arms 243 and 247, the lower part of the slots being parallel each with the other. This additional movement of the shaft 152 imparts additional movement to the arm 253, which gives additional clockwise movement to the hooked arm 231 placing it in its ineffective position in the same manner as described for a multiple-item total taking operation. With the hooked arm 231 in its ineffective position, the segment 174 will be permitted its full extent of movement during the second cycle of a total-taking operation, which will position the pin 173 to the right of arm 172 of the bell crank. When the segment 174 is returned to its normal position, the cam arm 168 will move the detent 164 to release the depressed clerks key.

The mechanism for giving the shaft 152 its additional movement, on total-taking operations, will now be described.

Cooperating with a roller 260 carried by a pitman 261 is a cam 262 (Fig. 1). Connected to the lower end of the pitman is a lever 263 pivoted on a stud 203 and connected at its opposite ends, by the link 264, to an arm 265 secured to the shaft 152. The cam 262 is freely mounted on the stud 54, and, is normally retained in its in operative position by the roller 260 being in a notch 266, formed in the cam. When the shaft 152 receives'its initial movement, by the total lever 34, as previously described, the roller 260 is withdrawn from the notch 266 into the groove of the cam 262. At the same time a coupling plate 269 is shifted to lock the cam 2.62 to the gear 263, in a well known manner whereby they will be made to rotate in unison. The cam 262, through the pitman 261, lever 263, link 264 and arm 265, now rocks the shaft 152 far enough to move the roller 256 (Fig. 12) to operate the arms 243 and 247 in the manner, and for the purpose above described, and

also to move the pitman 251 to perform the function stated. The movement of the pitman 261, through the stud 267, cooperating with the slot 268, will cause the link 124 to move clockwise, thereby placing the pin 204 in an ineffective position in the opening 205 so that the shaft will not be returned to its normal position until the second cycle of operation, all of which is old in the art.

Differential mechanism Differential mechanism such as that fully shown and described in the parent case, is provided to operate the totalizers differentially, and to select them for operation, also to set up type-carriers in the printer, controlled by the amount and transaction keys.

Briefly stated, such an amount differential comprises a driving segment having an invariable movement, differentially movable racks for actuating the totalizer wheels and a latch mechanism, which serves to connect the differentially movable actuating rack with the invariable movable driving segment. The differential mechanism which cooperates with the amount banks is similar to that used with the transaction banks, hereinafter to be described, except that a differentially movable member, carrying three actuator racks or segments, which cooperate with the three lines of totalizer wheels, is used instead of the arm 275.

It is not thought necessary to describe in detail the differential mechanism associated with the banks of amount keys as this structure is old and well known in the art, and forms no part of this invention. Reference may be had to theabove mentioned Shipley application for a complete disclosure thereof.-

Transaction differential v 274 which likewise is rocked clockwise and back toits normal position. The arm 275 is normally connected to the segment 274 by means of a latch 276. The arm 275 is given a clockwise movement until it is disconnected i from the segment 274 by a depressed key. As

the segment 274 moves counter-clockwise to its normal position the arm 275 is again connected thereto and returned to its normal position, all of which is old and well known in the art.

Associated with the differential mechanism is a beam 277 which at its right hand end is bifurcated to cooperate with a pin 278 in a link 279. The link 279 at its lower end is connected to an arm 280 secured to one end of a sleeve 281 (Fig. 10) on a rod 282.

The movement of the arm 280 also selects the classification totalizers into which the amount set up on the amount keys is to be added. This selection is effected through segment gear 283 secured to arm 280, rack 284, slide 285, cam lates (not shown) secured to the slide am cooperating with projections on totalizer frames 286 and 287 on which the transaction totalizers are mounted. The upper totalizer frame 288 carries agrand totalizer which is not under control of the transaction keys. As this totalizer selection is nota part of the invention claimed herein, and, as it is fully described in the previously mentioned parent application, no further description of it will be given here.
