Abstract: 406,654. Ticket printing and issuing machines; calculating apparatus. NATIONAL CASH REGISTER CO., Dayton, Ohio, U.S.A.-(Assignees of Robertson, W. H. ; 1302, Patterson Road, Dayton, Ohio, U.S.A.) July 27, 1932, No. 21170. Convention date, July 27, 1931. [Classes 106 (i) and 106 (iii).] Ticket printing and issuing and like machines, particularly adapted for recording postage and printing and issuing gummed postal labels, are provided with two totalizers on which all amounts are accumulated, one of the totalizers controlling devices for locking the machine when a predetermined value has accumulated. The mechanism, which is similar to that described in Specifications 285,500, 286,314 and 318,466, [all in Class 106 (i)], is enclosed in a casing 34, Figs. 1 and 13, secured to a base and is provided with openings for the various operating parts. The setting-keys are arranged in banks, the banks 37, 38 containing the value keys, the bank 39 the weight keys, and the bank 40 the postal zone keys. In addition, a repeat key 41, a lever 42 for setting the machine for performing adding or total-printing operations, and a release key 43 are provided. On actuating any key in the banks 37, 38 its inner end is moved into the path of movement of the segment 68, Fig. 2, corresponding to the bank and removes from this path a stop 61 which is normally in a position to arrest the segment at zero position. The segments are loosely mounted on a shaft 65 and are normally restrained from movement under the influence of springs 77 by a universal bar 75 carried by arms fast on the shaft 65. The bar 75 is moved clockwise and is then returned to normal position at the correct time during the operation of the machine, and during the first part of its movement allows the segments 68 to be moved by their springs until stopped by the inner ends of the depressed keys or by the stops 61. The bar 75 continues its movement and carries with it segments 90 also mounted on the shaft 65. These segments 90 are normally geared to the segments 68 by the broad pinions 86, but at the commencement of the operation of the machine, these pinions 86 are rocked out of engagement, for instance as described in Specification 285,500, [Class 106 (i)], and permit the segments 90 to be carried to zeio position by the bar 75. When the bar has completed its stroke, the pinions 86 are returned to couple the segments 68, 90 together, and the totalizer mechanism is rocked into engagement with the segments 68. The bar then returns, and carries the segments 68 with it so that an amount equal in value is added to the totalizer and also set on the printing-mechanism. One of the totalizers is visible through an opening in the outer casing, but the other is inside the machine. Both totalizers always show the same amount and cannot be reset. The latter totalizer is provided with a wheel 112 corresponding to each segment 68 and with two overflow wheels. The wheels are carried by a rod 113 supported by arms 114 on a shaft 116 adapted to be rocked by a link 128 and lever 126, Fig. 9, from a cam on the main shaft 80. The link 128 is restrained in its movement by means of a pin 132 engaging in a slot in the end of a lever 133, and is also provided with a pin 127 engaging a slot in an ear bent up from the lever 126 so as to permit its disengagement when required. The arm 126 is rocked to move the totalizer wheels 112 into engagement with the segments 68 when the bar 75 has completed its clockwise movement, and is again rocked to effect disengagement at the end of the counter clockwise movement of the bar. The printing- mechanism is set by the segments 90 which also act to drive the second totalizer through gears 135, 138, 152. The zone and weight gears 135 mesh with partial gears on the shaft 139 of the gears 138 and act in known manner. They do not co-operate with the totalizer, the totalizer wheels corresponding in position to the zone and weight gears being overflow wheels. The second totalizer is provided with a number of reading totalizer wheels 142, rotatable on a rod 144 carried by frames adapted to be rocked about a shaft 151, Fig. 6, to bring the gears 138, 152 into engagement. The frames carry a shaft 155 provided with a cam 156 co-operating with fixed studs 157, and a gear-wheel on the shaft 155 meshes with a segment 153 on the shaft 151 and rocked by a pitman 164. The pitman has a pin-and-slot connection with a lever 162 rocked by cams 158 on the main shaft 80, so that at the correct time the totalizer gears 152 are rocked into engagement with the gears 138. In order to prevent movement of the gears 138 after adjustment, a bar 145 is normally held in engagement with the teeth, the bar being attached to a rock-shaft 148 actuated by parts 237, 236, 235, 222 from the cam on the main shaft to permit rotation of the gears. The lever 42 acts to enable the accumulated total to be printed on an inserted slip without affecting the total, and to reset the total on the totalizer wheels. The lever 42 is pivoted on a shaft 65, Fig. 9, and carries a stud 213 engaging a slot in the lever 133, the lever being normally hold thereby to maintain the stud 127 of the link 128 in engagement with the lever 126. When the lever 42 is rocked clockwise from its normal position to the " read " or printing-position, the link 133 is rocked and disengages the link 128 from the lever 126 and couples it to the lever 222. The lever 222 is rocked by its cam to bring the totalizer wheels 112 into engagement with the segments 68 before the withdrawal of the bar 75, so that the totalizer wheels are rotated backwardly until their movement is arrested with the segments 68 in positions corresponding to the amount which stood on the totalizer wheels, the stops 61 having been thrown out of action by the movement of the lever 42. On the return movement of the bar 75, the segments 68, 90 are returned to normal positions, thus setting the amount on the type wheels. The lever 42 is formed with a cam surface engaging a roller 233 on a lever 234 fixed to a shaft 177 to which is also secured an arm 176, Fig. 6, having a pin engaging a cam slot in a bell-crank lever 168 connected by a link 166 to the pitman 164. Movement of the lever 42 thus results in disengaging the connection between the pitman and the lever 162 and locking the pitman against movement by moving a slot 180 therein into engagement with a fixed pin 181 so that the total shown on the upper totalizer is unaffected. Return of the lever 42 to " add " position resets the parts through the medium of a pin 256 and a cam surface 255 on the other end of the lever 234. Movement of the lever 42 to " read " position sets type-wheels, to print an indication that a " read " operation has been effected, through an arm 251 connected to an arm 253 secured to the outermost of a series of nested tubes 136 carrying the gears 135. The repeat key actuates mechanism similar to that described in Specification 285,500, [Class 106 (i)]. The type-wheels set by the segments 90 print on a strip of gummed paper which is fed out and severed, and also on a record strip which is kept in the machine. In order to print the totals on a separate slip, an aperture 499 for the insertion of the slip is provided in a door 498 in the casing giving access to the audit strip roll, the slip being held in position by a spring. The slot in the door and the communicating slot in the upper side of the casing are normally closed by slides 510, 502, Fig. 12, respectively carried by an arm 503 pivoted at 504 and having a cam slot at its free end engaged by a stud on a lever 520 itself under the control of a pin-andslot connection with one arm of a bell crank lever 515. The other arm of the lever 515 is under the control of an arm 511 connected to the arm 253, so that the apertures are uncovered when the lever 42 is moved to " read " position. A slide is arranged to close the lower end of the aperture 499 so that the slip can be arrested before the machine is operated in such a position that the total is printed in a certain position ; when the machine has completed its operations, the slide is moved, and the slip can be pushed further in to enable the total to be printed above the previously-printed total to facilitate subtraction. A lock 35 on a door 36 in the casing is provided, the key thereto being retained by the maker of the machine to enable the cabinet to be opened in case of breakage of the internal parts. A large door 528, Figs. 1 and 13, is provided for access to the motor, but is not large enough to enable the motor to be removed until the door 36 is opened. A notched stud 532 co-operates with a bolt 531 on the lock, and a shield 533 is provided to prevent access to the totalizers when the doors are opened. The back 534 carries a clip 535 adapted to slip into a bracket 536 on the back of the totalizer frame, and a bracket 537 projecting under the upper part of the main cabinet so that when this is locked in position the back cannot be removed. A collar 529 sealed on the lock 35, and a similar collar 360 sealed on a lock 349 have shouldered portions of larger diameter than the openings in the casing 34 through which their smaller parts pass, so that the casing cannot be removed from the machine until the collars are removed. Actuation of the release key 43 permits a link 277, Fig. 9, to fall and connect the mechanism to a driving-motor. The link carries a pin 313 engaged by a slotted arm 311 connected to a bail 308 pivoted about a shaft 228, and on movement of the link, the bail is moved into position to lock all the keys. The shaft 113 of the lower totalizer carries one or more projections 338, Fig. 4, secured to the totalizer wheel of highest order which act to lock the machine against further operation after a predetermined amount has been added to the totalizers. The tappets engage a pivoted finger 336 and force it against a lever 333 pivoted at 334, and formed with a slo
