Abstract: 604,165. Cash registers. NATIONAL CASH REGISTER CO. Nov. 20, 1945, No. 31210. Convention date, Dec. 6, 1944. [Class 106 (i)] A cash register of the Shipley type is adapted to print railway tickets having a main portion and a stub portion with two identical series of records, the ticket being fed backwards and forwards, after insertion into the machine, to receive the type impressions with proper line spacing. Alternatively, a coupon type of ticket with a single set of printing may be prepared, the automatic feeding being replaced by hand feeding. All the transaction keys release the machine, but in certain total-taking operations, the release bar must be used. There are interlocks between the auditor's key and the amount keys and between the auditor's key and the operators' keys. The auditor's total can be read by moving the main control lever to No. 2 Read and depressing the start bar, but moving the lever to No. 2 Reset locks the machine unless the auditor's key is depressed after being unlocked. Totalizers. The totalizers are arranged in three lines, No. 1 having one set of item totalizer wheels 62 selected for engagement with the amount actuators by the item keys 48-54, the No. 2 line has four sets of totalizer wheels 63 corresponding to the four operators' keys 56 and one set of wheels corresponding to the auditor's total key 58. The No. 3 line has seven sets of wheels 64 corresponding to the seven item keys 48-54. Amount keys and differential mechanism. Depression of any one of the amount keys 47, Fig. 9, rocks a zero stop lever 68 in known manner, and at machine release the main camshaft 46 makes one clockwise revolution to rock a lever 85 first clockwise and then back to normal position so as to rotate a drive segment 83 clockwise and back again. The segment 83 carries an actuator 76 with it until an extension 91 of a bell-crank 75 contacts the stem of the depressed amount key 47, when the bell-crank 75 shifts a latch 79 forwardly to release the actuator 76 from the drive segment 83, simultaneously moving a forward extension 93 of the latch 79 into engagement with one of a series of notches 94. After the actuators for the several amount banks have been positioned in this manner, the selected totalizer shafts are moved inwardly in known manner to engage the corresponding totalizer wheels 62, 63, 64 with the corresponding teeth 110, 111, 112 of the amount actuators 76, the totalizers being advanced by the return movement of the actuators. The differential movement is transmitted by means including a beam 96, pin-andslot connection 98, 99 and a link 100 to the indicating and printing mechanisms, known means being provided to limit movement from one entry to the next to a minimum. Transaction keys and differential mechanism. The transaction keys 48-54, Figs. 1, 10, and the ticket number key 55 are in one bank and control differential mechanism generally similar to the amount differential mechanism, so as to control the associated totalizers in the No. 3 line through a slide 149, Fig. 9, which imparts transverse movement to a slide 150 coupled to the totalizer line. The ticket number key 55 does not control any totalizer. Minimum movement mechanism controls a link 144 which positions indicating and printing mechanism according to the key depressed. Operators' keys and differential mechanism. A differential arm 161, Fig. 15, is mounted on a stud 162 and is driven by a cam groove (Fig. 16, not shown) through a latch mechanism carried. on a shaft 169. The latch mechanism comprises a driver 171 rotatable on the shaft 169 and connected to a cam follower 174 by a link 173. A latch 167 pivoted to a plate 168 also rotatable on the shaft 169 has a shoulder 182 normally engaging a step on the driver. An upwardly extending arm of the latch is coupled by a pin 166 to a lever 165 connected by a link 163 to the differential arm 161. When a nose 160 of the arm abuts a depressed key, or if no key is depressed when a shoulder 329 abuts a fixed stud 330, the pin 166 is arrested to disconnect the latch from the driver and engage a tooth 182 of the latch with one of a series of aligning notches 183. The plate 168 is thus positioned and near the end of the initial movement of the cam follower 174, a roller 192 pushes a beam 187 against the hub of the shaft 169 to set the beam 187 with minimum movement, the differential setting being communicated by a link 189 and printer segment 190 to the operators' type wheel 191, Fig. 23. The beam 187 also sets the shaft 169 which drives a gear segment 194, Fig. 9, and a rack 195 and slide 196 to position the indicating mechanism, and through a plate 199 and arm 201 to position the No. 2 totalizer shaft laterally to align the appropriate operator's or auditor's. totalizer with the amount actuators 76. After the amount actuators have been set in adding operations, the totalizer wheels are shifted inwardly to engage the actuators which return to home position after which the totalizers are disengaged. The differential arm 161 then returns to home position, but the indicating, printing and totalizer selecting mechanism remain in their selected positions until the next machine operation. Totalizer engaging mechanism. The totalizer engaging mechanism is generally of known type and is controlled by a lever 61, which can be set in central position for adding, upwards to any of three positions to select any of the three totalizer lines for reading, or downwards to any of three positions to select the totalizer lines for resetting. In adding, the machine requires one cycle only, but in reading or resetting, an additional cycle is required, the first cycle being used to engage the selected totalizer with the amount actuators. Manual movement of the lever 61 to any of the reading or resetting positions rocks a zero-throwout shaft 230, Figs. 9, 10, clockwise, but not sufficiently to render the zero stop levers 68 ineffective in the first cycle of a reading or resetting operation. Near the end of the first cycle, however, the shaft 230 is given an extra, movement by known means to rock the zero stop levers 68 so that the differential actuators 76 are free to move clockwise to be positioned under the influence of the selected totalizer. In reading and resetting operations, the totalizer wheels engage the actuators before the actuators are moved clockwise, which movement zeroizes the totalizer. In resetting operations, the totalizer wheels are then disengaged, but in reading operations the wheels remain in engagement with the actuators while the actuators are returned to home position to restore the totalizer to its former condition. Movement of the control lever 61 to No. 1 or No. 2 reading or No. 1 or No. 2 resetting positions automatically rocks a stop pawl 236, Fig. 10, clockwise to maintain the transaction differential mechanism in zero position so that none of the totalizers in the No. 3 line is selected. Automatic total transfer mechanism. Movement of the lever 61 to No. 1 reset position clears the No. 1 totalizer line and transfers the amount to the auditor's totalizer in the No. 2 line. A stud 263 (not shown) on the lever 61 co-operates with a spring-pressed cam lever, not shown, to rock a yoke 270, Fig. 15, counterclockwise to move a shoulder 276 beneath an extension 278 of the link 163 to obstruct movement of the operators' latch mechanism so as to have the same effect as depressing the auditor's total key 58. At the same time, the stud 263 operates a linkage, Figs. 17-20 (not shown), to rock the No. 2 totalizer engaging shaft 229, Fig. 9, counter-clockwise to engage the auditor's totalizer with the amount actuators 76 at the end of the first cycle, transfer taking place in the second cycle. Reading and resetting auditor's totalizer. A lock 59 prevents an unauthorized person from resetting the auditor's totalizer, but this totalizer may be read at any time by moving the lever 61 to No. 2 reading position and depressing the release bar 60. The lever 61, through link 303, Fig. 15, and gears 305, 306, 308, 309, positions a control plate 310 to hold a lever 313 in counter-clockwise position except when the lever 61 is moved to No. 2 reset position when the lever 313 is held by a control plate 317. Depression of the auditor's total key 58 by an unauthorized person shifts the control plate 317 to rock the lever 313 clockwise, whereupon a tail 322 of the lever locks a shaft 325 to prevent operation of the clutch between the motor and the machine. If the auditor has released the lock 59, however, the lever 313 is locked in counter-clockwise position and does not prevent resetting of the auditor's totalizer. When the lever 61 is in No. 2 reading position, the plate 310 holds the lever 313 in ineffective position, and depression of the key 58 enables the auditor's totalizer to be read. As the control plate 317 is moved only by the key 58, the lever 313 does not prevent the resetting of the No. 2 totalizers corresponding to the operators' keys 56. The control plate 317 provides an interlock between the auditor's key and the operators' keys. The auditor's total key 58 is not motorised and so the release bar 60 must be used to start an auditor's total or sub-total operation. Any of the keys 56, 58 may be released by a fingerpiece 331, Fig. 1. Printing mechanism. Printing wheels 106, 155, 191, Fig. 23, corresponding to the amount keys 47, the item keys and the ticket number key 48-55, and the operators' and auditor's keys 56, 58, carry two diametrically opposite sets of type for co-operation with a platen 335 for printing on an audit strip 333 line spaced automatically in known manner, and with platens 338, 340 for printing on an inserted slip 334. The platens 338, 340 are operated by an item hammer 339, Fig. 23, and a consecutive number and date hammer 341, Fig. 25. Once each cycle, a pitman 363, Figs. 22, 23, is moved to the right by cams 368, 370 to displace a hook 360 to release the h
