Description

rojecting laterally from an arm 497 astened to a rock shaft 498 projects. The initial movement of the shaft 438 places the right hand end of the elongated opening 495 in contact with the in 496. And as the machine is operated eshaft 498 is rocked counter-clockwise bya further movement .of the link 494 by mechanism to be hereinafter described. I
Secured to the shaft 498 is an arm 499 having a. pin 500 projecting into a slot .501 formed in a sliding coupler 502 guided in its movements by studs 503 mounted in a drawer lunger lever 504 and extending into a set 505 in the sliding coupler. As the arm 499 moves counter-clockwise the coupler 502 moves forward, placing the shoulder 506 in a position to be contacted a projection 507 on the arm 479 secured to the shaft 478. With the coupler 502 in this forward position, the counter cloekwise movement of the shaft 478 will cause the drawer plunger lever 504 to swing in a like direction and lift a drawer plunger 508 to release thecash drawer 473.
The drawer plunger is mounted in abase 509 of the frame with a s ring 510 entwined about the plunger etween a pin 511 and the'base. A col'lar 512 secured to the drawer plunger, above the base, controls the lower position of the lunger. In the upper end of the plunger is a vertical slot, in which the drawer plunger lever freely operates. A horizontal 'n 514 secured in the plunger passes t r h an elongated opening 515 formed in the rawer plunger lever. The opening 515 in the rawer plunger lever (is e10 ated to permit the plunger to rise, when c osing the cash drawer, without moving the'lever and also toallow a greater movement of the lever than that required to lift'the plunger.
A spring 516 attached to a stud 517 mounted in the base and to the arm 497 moves the shaft 498' clockwise to return the coupler 502 to normal position.
As the plunger uses it is withdrawn from v a -bracket 518 fastened on the back of the cash drawer, allowing a spring 519 to move the drawer forwardly. As the drawer moves forwardly a bell crank lever 520 freely mountedupon the shaft 498 moves -clock= wise under the action of a'spring 1 (Fig. 42) until an car 523 formed on the lever 520 engages a shoulder 522 formed on the link 494 which-has been moved forwardly during the operation of the machine. With the link 494 latched in its forward position the totalizing lever 172 cannot be returned to the adding position. 'This condition makes it necessary to return the cash drawer to its normal position, which moves the lever 520 counter-clockwise and moves the ear 523 from the path of the'shoulder 522 on the link 494.
r The drawer plunger lever, in addition to releasing the cash drawer, operates the bell mechanism. The forward end of this lever 504 has a formed car 528 which normally contacts a pin 529 projecting laterally from a bracket 530 secured to the base 599. Freely mounted upon a stud 531 secured in the bracket 530 is a bell hammer 532. In the normal position of the hammer a shoulder 533 thereon engages a pin 534 projecting laterally from the bracket '53 This hammer is retained in its normal position by a spriug 535 attached to a pin 536 on the frame and to a trip pawl 537 freely mounted in a stud 538 secured in the bell hammer. The x trip pawl 537 has a forwardly extending arm 539 normally in contact with a pin 540 on the hammer, and also an upright extending arm 541 in the plane of the ear 528 on the drawer plunger lever 504. As the draw- 1 or plunger lever moves counter-clockwise the ear 528 engages the arm-541 and causes the bell hammer to move clockwise on its pivot until the ear disengages from the arm, as the ear and arm rotate in opposite directions, at which time the bell hammer returns to normal position under the tension of the spring A pin 542 mounted in the arm 479 contacts a projection 543 extending downwardly from the drawer plunger lever, and as the shaft 478 moves clockwise this lever position.

[a general Described in general terms, the machine in its preferred form includes a plurality of totalizers one for each classification of transactions, and one for totalizing each separate transaction. These totalizers are operated by differential mechanisms under the control of the manipulative means in this case, the amount keys.
The differential mechanism provides means for adjusting the printing mechanism 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, transaction and classification totals.
The differential mechanism also provides means for adjusting the indicating mechanism to indicate the amount of each item recorded and the total of the items of a transaction.
The printing mechanism includes a single amount type line date type wheels, consecutive number type wheels, and suitable electros. The amount and transaction type wheels are set differentially by tube lines and a train of gears. The date type wheels are set by manually operated knobs in the usual manner. The consecutive number type wheels are operated by a differentially tined pawl.
This machine, in its present embodiment. is especially adapted for use in places of business where it is desirable to issue an itemized printed receipt to the customer and also retain in the machine a record strip containing the totals of each transaction.
hen the total of a transaction is printed the transaction totalizer is restored to normal or Zero position. A sub-total from a classification totalizer may be printed and the totalizcer not restored to Zero, or a total may be printed and the totalizer restored to Zero.
Operating madam-5am. The machine is manually operated by a handle (Figs. 1 and 2) provided with a stud 56 extending into a short tubular bearing s cured to the right hand frame of the machine. Connected to the handle 55 is a pinion 57 meshing with a gear 58 mounted on a stud 59 projecting from the frame of the machine. The gear 58 meshes with a gear 60 secured on the main driving shaft 6 The ratio of the pinion 57 and gear 60 is such that I 30) mounted on. the left side frame that patent. Only a part of the motor frame and the switch for the motor, and a part of the clutch mechanism for the motor are shown in the accompanying drawings. 7
The motor is carried by a frame 62 (Fig. the
mine. A clutch shell 63 (Figs. and 27 forming one part of the clutch device, lad-shown m section in Fig. 27, is rotated by a worm 64 (Fig. secured to the armatun! daft of the motor and in mesh with a worm gear 65 secured to the clutch shell 63. K pinto 66 (Fig. 27), forming'another memberet the clutch cooperates with rollers 67 carried by a disk 68 and is connected there'- to the clutch shell 63 upon release of in the aforesaid Kettering and Chryst patelltz- Thedisk 68 has a shoulder 69 (Fig. contacting the end of a lever 70 (Fig. W 40) mounted on a stud 71 on the frame of the machine. An arm 72 (Fig. 40) secured to the lever 70 carries a pin 73 which norwally rests on a curved edge74of an arm 75 freely mounted on a shaft 76, journaled in the rinter frame. The arm 7 5 is connected y a link 77 to a bell crank lever 78 to a shaft 79 extending across the entire machine, and journaled in the frames thereof. When the bell crank lever 78 is rocked clockwise to release the machine, as
term a printer frame 82, to move the lever 700m of the path of the shoulder 69. The clockwise movement of the lever is limited by a pin 84 (Fig. 40) projecting iromthe frame of the machine. Upon releaseof the Fever 70 the disk 68 is moved forwardl by spring actuated plungers 85 (Fig. 27{ to m the rollers 67 into operative position, amia tally described in the above mentioned Kettering and Chryst patent. The movenew: the lever 70 also releases a spring actuated disk 86 which, as it moves in a 1 I direction, rocks a yok'e 87 pivoted on I stud 88 (Fig. 26) counter-clockwise, and thereby closes theci'rcuit through the motor. One side of the yoke 87 carries a rolier89 contacting the disk 86. The opposite side of the yoke engages a rolier-QO (Fig. 30) carried on an arm 9I,-prov'ided with an insulating block 92 to lower a twitch biade 93 into contact with a switch machine, as fully shown and described blade 94, thereby closing the circuit through the motor. The clutchplate 66 (Fig. 27),
is fastened on a sleeve 95 mounted on a stud 96 on the frame of the machine. A gear 97 (Figs. 25 and 40), secured on the sleeve 95 mesheswith a gear 98 on a stud 99 on the frame of the machine. This gear 98 also meshes with a gear 100 fastened to the shaft 76, rotated once at each operation of the machine. Secured to the gear 98is a ear 101 meshing with a gear 102 fastene to the shaft 61, which rotates once at each operation of the machine.
. The lever 70 is restored to locking position, near the end of the operation of the machine, by a cam 103 (Fig. 40) secured to and rotating with the shaft 76. This cam contacts an extension 104 on the arm 72 and moves the lever 70 in a counter-clockwise direction to move the lower end of said icver'70 into the path of the shoulders on home position at time end of an operation.
This device consists of a cam 105 secured to the shaft 61 and cooperating with a roller 106 carried by a stud mounted on an arm 107 pivoted at a point 108. A spring 109 is attached to the right hand end of this arm and to a pin projecting from the side frame of the ,machine. As the shaft 61 rotates clockwise, the arm 107 is moved in a, like direction and gradually increases the tension I on the spring until near the end of the operation, when the contour of the cam permits a rapid return of the arm 107'by the spring I Keyboard.The keyboard mechanism at the present machine is the same as that shown and described in the Shipley Patent No. 1,619,796, and reference is hereby made the same. Only a brief description of the keyboard and its cooperating mechanism will be given herein- The keyboard includes four banks of thereto for a full and clear description of amount keys, one bank of transaction or' mounted in an individual frame 111 (Fig.
18) mounted on crossrods l12'carriedbythe machine frame. The keys are retained in their normal outward positions by compression springs 113.
When a key is depressed it cooperates with a detent 111 (Fig. 19) and is thereby retained in its depressed position, as is well known in the art. Each bank provided with a zero stop pawl 115, pivoted to the frame of the bank and adapted to rocked to ineffective position upon the depression of any key in the bank, and held in this position until the parts are again returned to normal.
The present machine is normally released for operation by the depression of the starting key 116 (Fig. 11), which releases the shaft 79 to rock clockwise (Figs. 1% and to move the arm from beneath the stud 73 to release the motor as before described. Depressing the starting key moves a pin 118 (Fig. 1%), projecting from the key, into contact with an inclined wall 119 of a notch in a release bar 120 supported by links 121 and 122 pivoted on studs 123 and 12d fastened in a key frame 125. link 121 (Figs. 1-1 and 17) has a hater projecting pin 126 cooperating with a 127 in an arm 128 pivoted upon which extends through the machine and is supported at each end by the fran'ies of the machine. As the starting key pin 118 contacts the release bar 120 the arm 128 is rocked in a counter-clockwise direction. Fastened to the arm 128, by a rivet 130 and a stud 131, is release pawl 132, which is freely mounted upon the rod 129 and moves with the arm 128. As the release pawl 132 moves in a counter-clockwise direction it moves out of contact with the flatside of a pin 133 on an arm 139, connected to the shaft 79 in a manner to be presently described. As the arm clears the pin 133 it permits the shaft 79 to rock clockwise, to release the motor clutch mechanism, previously described. A non-repeat pawl 136 freely mounted upon the rod 129 is normally held in contact with the lower side of the pin 133 by a spring 137 attached to a pin secured in the nonrepear pawl and to a pin secured to the arm Should the starting key be held depressed during the entire operation of the machine the non-repeat pawl 136 moves coiuiter-clockwise in front of the flat surface of the pin 133, as the pin moves toward the right. during the o eration, and prevents a repeat operation. Tao release pawl 132 is formed so as to overlap the edge of the non repeat pawl 136 at the point 138 to return the non-repeat pawl to its normal position.
The flat sided pin 133 is mounted in an arm 139 projecting from a sleeve 110 freely mounted upon the shaft 79 (A ig. This sleeve has a finger letl extending forwardly to engage a pin 14:2- mounted in an arm 1 13 secured tothe shaft 79 (Figs. 15 and 16).
An arm 14 1 (Figs. 2 and 15) is fastened to the shaft 79 outside the right hand frame of the machine. The arm 141 carries a screw stud 115 upon which are pivoted two spring clips 116.. placed on each side of a link 1217 slotted to move over the stud. A coil spring surrounding the lower ends of hese clips is compressed, between shoulders on said clips and the lower wall of a slot 1 19 in the link i 7 From this it can be seen that as the starting key is depressed and pawl arm 132 (Fig. 17) moved counterclockw'se, the spring 1-18 (Fig. 2) is released to rock the shaft 7 9 clockwise to release the motor clutch mechanism, previously described. The movement of the shaft 79 is limited by a fl. r on the arm 11% and a stud 151 projecting laterally from the frame.
The star-tins key 116 1%) cannot be release the n chine for operation until one of the transaction keys 152 is depressed. A pin pro ecting laterally from a dot 151. is normally in the path nt of a shoulder 155 on the starting key. When a transaction key is depressed a projection 156 thereon contacts a pin 157 mounted on the detent 151- and moves the detent downwardly and the pin 153 out of the path of the shoulder on the starting key.
After a transaction key is depressed it can be released only by oepressing another transaction key or by depressing the release key 158, which has an inclined edge 1.59 contacting a pin 160 mounted in the detent 15 1.
The transaction keys cannot be depressed while the starting key is held in its depressed position, because when the starting key is depressed the pro ections 161 on the release bar 120 are moved into the path of key pins 162. The release bar 120 is held in normal position by a spring 163.
The amount keys 110 (Fig. 19) are also locked against manipulation after the starting key is depressed by a universal rod 168, carried between arms 167 secured to the shaft 79. The ui'iiversal rod 168 extends into a slot 169 in a link 170 pivoted on a stud 171 for each bank of amount keys. This link is connected to a l cking bar (not shown) which. when the shaft 79 is rocked in a counter-clockwise direction, is moved into position to lock out the aforesaid keys, as is fully described in the Shiplcy patent previously referred to.
Depressing the starting key also locks the totalizing lever 172 (Fig. 5) against manipulation. The pin 131 (Fig. 17), projects into a slot 173 in a yoke 17-1 freely mounted upon the shaft 79. The lef hand side of the yoke has a laterally projecting pin 175 contacting an angle edge 176 formed on a second yoke 177 freely mounted upon the rod 129. Afer the farting key is depressed,
55 mounted u to yoke 177 is moved clockwise, causing an on: 178 to enter one of several slots 179 in the totalizing lever plate 166. spring 180 normally holds the car 178 of the yoke 177 out'of the slot 179.
Near the end of the operation of the machine the parts operated by the depresaion of the starting key are restored to their normal itionsby a cam'181 (Fig.
w 2. formed in t e gear 58. Cooperating with is cam is a roller 182 mounted on a stud carried by a lever 183 freely mounted on a stud 184 projecting'from the side frame of the machine. The upper end of the lever u 183 carries a pin 185 which normally engages a slot 186 formed in the link 147. As the gear 58- rotates, the armis moved first clockwise and .then counter-clockwise, which 0011888 the link 147 to move downward and g return. When the machine is released for operation, the stud 145 moves against the upper wall of the slot in the link 147, and, therefore, when the lever 183 lowers the link 1147 the shaft 79 is rocked counter-clock- 3| .wise. This movement of the shaft 79 moves the pin 142 (Fig. 16) into contact with a lever 187 freely mounted on the shaft 129.
.As this: lever is moved counter-clockwise its lower end 188 contacts a pin 189 mounted a in the erm 139 and moves this arm in a counter-clockwise direction, which restores the pin 133 (F i 17) to its normal position, allowing all 0t er parts cooperating with said pin to return totheir normal ositions. The total lever 172 is provide for the pose of controlling the machinein total and sub-total printing operations.
Difl'erential mechanism 0 The differential mechanism of the machine is employed to operate the different totalizers, to select them for operation, and also to set type carriers, in the printing mechanism, as controlled by the banks of (.5 amount keys and the bank of transaction The amount differential mechanism w'l be described first.
.Dc'femntz'ak-Amownt banks-There is a difierential unit for each of the four I! amount key banks and two extra units of higher denominations operated in adding operationsonly when a transfer to them is necessary. Each unit is supported by hangers 195 and 196 (Figs. 18, 19 and pon rods 197. A rod 198 extends through all of the differential units, including the transaction unit, and acts as a stabilion;- for said units.
Each difierential unit is driven by a pair of cams 199 and 200 fixed on the shaft 61. These cams cooperate with rollers 201 and 202 respectively on a Y-shaped lever 203 ivoted on a stud 204 on the hanger 195.
8 110 airs of cams 199 and 200 are arranged I spirally on the shaft 61, that is, the units from the driving segment 209.
cams are set slightly ahead of the tens cams, the tens cams slightly ahead of the hundreds cams, etc- This arrangement of cams is illustrated in the above mentioned Chryst Patent No. 1,230,864 and isfor the purpose of entering transfers successively as is well known in the art. I
To the upper end of the lever 203 is pivot ed a link 208 pivoted to a driving segment 209 loose on a hub 21.0 fastenedin the hanger 1.96. The cams 199 and 200 (Fig. 19 oscillate the lever 203 first counter-clockwise and then clockwise to normal position, thus movement'through the link 208 rocking the driving segment 209 first counter-clockwise and then clockwise to its normal position.
There are two totalizer actuating segments 211 in each unit, mounted between and secured to two nearly circular disks 212 and 213 having fast thereto a hub (not shown) journaled on thehub 210. The actuating segments 211 operate totalizer pinions 214 of the front and back totalizer lines, to be hereinafter described. The differentially movable disks 212 and 213 are connected to the invariably movable segment 209 by a latch 215 carried by a bellcrank 216 and a link 217 pivoted at 218 and 219 respectively to the disks 212 and 213. A foot 221 of the latch 215 is normally held in contact with the segment 209 above a shoulder 222 by a spring 223 (Fig.18) stretched between the upper end of the bell crank 216 and'a pin mounted in the plates 212and 213.
By this latch connection the plates 212 and 213 and segments 211 are rotated coun ter-clockwise (Fig. 19) until an arm 224 of the bell crank 216 strikes the end of a depressed key. When this occursthe bell crank 216, link 217 and latch 224 are moved clockwise, thereby removing the foot 221 from the shoulder 222. The foot 221 then rides upon the outer periphery of the segment 209 as the segment continues itsinvarb able movement. When the latch is thus disioo' connected the forward end thereof engages one for each of the nine keys, and one at the zero position. \Vhen there is no amount key depressed the latch is disconnected in the zero position. Adjacent the disk 212, and pivoted on the center 198, is a reset spider 230 (Fig. 18) having an arm 2531 provided with a slot into which a stud 232 carried bythe arm .224 projects. The arm 231 is in the plane of the zero stop pawl 115, and when there is. no key depressed the upper edge of the arm 231 strikes the pawl 115, thereby disconnecting the latch 215 This arrests the rotation of the segments 211 and their supporting members.
