Patent GB-810797-A (GB)
Abstract: 810,797. Calculating-apparatus. BURROUGHS CORPORATION. July 10, 1956 [July 18, 1955], No. 21352/56. Class 106 (1). [Also in Group XVI] A totalizer of an accounting machine is split to provide a counting section in addition to the amount section, and counting may take place additively or subtractively irrespective of whether the amount section is conditioned for addition or subtraction. The invention is applied to the machine disclosed in Specification 709,181, modified, as described in U.S.A. Specification 2,807,412, by the provision of four interspersed totalizers on the rear line. All the totalizers are split into amount and count sections. Total counts may be set on the four leftmost columns of keys for entry by means of the normal differential actuating mechanism into the count sections of the front (crossfooter) totalizer and a selected rear totalizer and total counts may be transferred from the front totalizer to a selected rear totalizer. The platen on the paper carriage is divided to form a small tally-strip section 1057L which when in printing position is linespaced independently of the main section. The machine is particularly adapted for banking transactions and a list of cheques may be made on the tallystrip as the amounts are added on the front totalizer. At the same time the number of cheques is counted on the count section of that totalizer. When a subtotal is taken, the carriage is automatically skip-tabulated to an Item column, where in a repeat sub-total operation, the total amount and number of cheques are printed. Count section of front totalizer.-The front (A) totalizer frame 766, Fig. 5, carries on the left four pairs of intermeshing pinions 4140, 4141 on the rods 771, 772 which carry the corresponding intermeshing pairs of pinions of the A totalizer. Each set of pinions 4140, 4141 is movable axially with a sleeve, the two sleeves being movable in opposite directions, to align one set of pinions or the other with the associated actuators 511, by a plate 4148 rockable by a lever 4150. This movement is independent of the similar movement imparted, as described in the prior Specification, to the pinions of the A totalizer. The forward count pinions 4141 are constantly aligned with the pawls 830 and segments 850 of the transfer mechanism. No fugitive one mechanism is provided in the count section and its lower order transfer segment 850 is held stationary. Normally, the forward count pinions 4141 are aligned with their actuators 511. However, if a shaft 4167, Fig. 4, is rocked, as described below, a link 4164 is lowered so that, when it is moved rearwardly by a cam stud 4174 on the mainshaft 126, a stud 4162 in a lever 4160 will be shifted. The lever 4160, and the lever 4150 controlling axial movement of the count pinions, are thus rocked to align the rearward pinions 4140 with the actuators. The count pinions are meshed with their actuators in the same timing as the totalizer-pinions (viz. during the return and forward strokes respectively for addition and subtraction) and consequently, when the forward pinions 4141 are aligned with the actuators, the count is algebraically in the same sense as the entry into the totalizer, whereas, when the rearward pinions 4140 are aligned, the count is in the opposite sense. When a total or sub-total is taken from the front totalizer, a stud 4178 is raised to prevent lowering of the control link 4164 so that the forward pinions 4141 determine the total taken from the count section. Item-counting: control by carriage.-The rear interspersed totalizers also have count sections as described below and counting units may be entered into both the front totalizer and a rear totalizer under the control of lane 24 of the carriage programme limit. When the sensing pin 4180, Fig. 11B, for lane 24 encounters a No. 4 projection, a stud 4187 in the control lever 4181 releases transverse slides 4188, 4189. If these are free to move, notches therein release a longitudinal slide 4200 controlled by an arm 4202 cam-operated in synchronism with the differential slides. If this is also free to move, a stud 4210, Fig. 4, therein cams a lever 4211, shaft 4212 and arm 4214 so that the latter enters the path of a stud 4216 in the stop bar 483 of the lowest count order. This stop bar is thus arrested in position " 1 " instead of moving freely to zero position, and a unit count is entered into the front and selected rear count sections. The transverse slide 4188 is blocked, under the control of the key-locking mechanism, if no amount key has been depressed and the slide 4200 is blocked by a stud 4206 in the transverse bar 3352 described in U.S.A. Specification 2,765,980, which selects the rear totalizer under the control of programme lane 25, when the No. 1 rear totalizer is selected. Movement of the arm 4214 to arrest the lowest count order stop bar 483 in position" 1 " is prevented by depression of any key in the three upper count orders, each of these orders having a slide which is cammed forwardly on depression of a key to rock a bail 4243 having a hook 4244 which latches under arm 4245 on the shaft 4212. Depression of a non-count key 4102, Fig. 4, rocks an arm 4266 on the shaft 4239 so that the latch 4244 blocks operation of the stop arm 4214 for the units count order. Item-counting in front totalizer: add/subtract control.-The count section of the front totalizer counts additively when engaged in add timing during an addition operation in the front totalizer. On depression of the subtract key for the front totalizer or on operation, under carriage control of the subtract link, a bail, Fig. 14 (not shown), is rocked to rock the control shaft 4167, Fig. 4, so as to cause, as described above, the alignment of the rear count pinions 4140, Fig. 5, with the actuators. Thus, although the totalizer is engaged in subtract timing, a unit, or an amount set on the count orders of keys, is added into the count section. In a correction operation under the control of a key 326, Fig. 11A, or a key 4103, in which an amount is added into the front totalizer to cancel the erroneous subtraction of that amount, the count section is actuated subtractively. For this purpose the keys 326, 4103 rock a lever 2166 having an extension 4260 coupled to rock the control shaft 4167. Similarly, when the correction key 320 is depressed to cause addition in the rear totalizer line, a mechanism 4262, 4264, 4265 actuates the front totalizer control lever 920 to cause subtraction in the front totalizer. As the forward count pinions 4141 remain aligned with their actuators and as the operation takes place in subtract timing, subtraction takes place in the count section. Count sections of rear totalizers: add/subtract control.-The actuators 511, Fig. 11B, cooperate also with a rear line of four totalizers comprising interspersed pinions 2803. The totalizers are split between the tenth and eleventh orders by the removal of a transfer pawl finger so that the four highest orders, which are laterally compressed to correspond to their closely-spaced actuators, may be used as a count section. In addition to the entry of counting units by the actuators associated therewith as described above, counting units may be entered additively or subtractively into a counting unit section corresponding to the selected totalizer by movement of the transfer link 834, Fig. 9, upwardly or downwardly. For this purpose, a stud 4270 in the link is actuated by one arm 4271 or the other 4272 of a lever on a shaft 4273 carrying a lever 4276 with studs 4277, 4278. According to the position of a slide 4287, Fig. 11A, a cross-slide 4290 carried thereby will, on depression, engage one or the other of these studs so as to operate the transfer mechanism. The slide 4287 is normally positioned so that the unit will be entered additively. The cross-slide 4290 is depressed by a stud 4295 in a bial 4296 connected by a link 4298 with a bail 4300 actuated, through a by-pass pawl, by a slide 4311, Fig. 11B, controlled synchronously with the actuators. The slide 4311 is released by the cross-slide 4188 if an amount key is depressed but is further controlled by a pawl 4315 normally latching it at 4316. If there is no control projection in programme lane 17, the corresponding control lever 4320 fully depresses the pawl 4315 to latch the slide 4311 at 4318 but if a No. 7 projection is effective, the pawl releases the slide and a unit is entered into the count section. Depression of any of correction keys 320, 326 or 4103, Fig. 11A, is arranged to rock the control lever for the rear line to subtraction position, to rock the ribbon control lever, and to shift the slide 4287 so that count units will be entered subtractively. Other counters.-A counter 4341, Fig. 1, is actuated by a slide 4339, Fig. 11B, similar to the slide 4311 and controlled in similar manner by the cross slides 4188, 4189 and 3352 to count selected items. Other counters may be controlled in the same fashion. Control of carriage movement: lane 15.-As in the modification of the machine described in the prior U.K. Specification, a No. 5 projection in lane 15 prevents operation of the carriage return and line-spacing mechanism whereas a No. 7 projection prevents line-spacing only. The lane 15 control lever 2238, Fig. 15, is blocked, however, by a link 2243 except when operation is initiated by either the uppermost or the lowermost motor bar 292, 294, Fig. 1. In the present machine, the lane 15 control is also effective in the case of an operation initiated by the front totalizer sub-total key 322, this normally causing a carriage return. When the lane 15 control is blocked, a skip-tabulation occurs. Line-spacing and suppression of tabulation under carriage control: lane 19.-If none of the motor bars 292, 294 or 322 is depressed, and a No. 5 projection is effective in lane 19, the lever 4359, Fig. 15, is rocked and a link 4362 rocks a lever 4
