Abstract: 158,084. Haddan, A. J. H., (National Cash Register Co.). Oct. 27, 1919. Statistical machines with several totalizers: printing totals.-Comprises totalizer-selecting mechanism for machines controlled by punched record-sheets having a plurality of totalizers with a set of differentially movable actuators common thereto, the various totalizers normally being out of engagement with the actuators, but being selectively brought into engagement by electrical means controlled by the punched record-sheet. In the machine illustrated diagrammatically in Fig. 15, there are five rows of totalizers, the first four rows having fourteen totalizers while the fifth has thirteen. The machine is arranged for fourteen clerks, the first four rows of totalizers representing totals under " cash," " charge," C.O.D. and grand total for each clerk. The six on the left in the fifth row of totalizers represent totals for departments, while the two groups of three totalizers on the right represent respectively grand totals for each class of transaction, and cashier's totals, the central and thirteenth totalizer in the last row representing the number of the machine from which the record-sheet is taken. Each totalizer, Fig. 4A, comprises a set of registering wheels 103 each rigid with a pinion 104 and loosely mounted on a shaft 105 the ends of which are carried by a lever 107 and bellcrank 108 pivoted at 109. Journaled on studs 110 on the levers 107 are levers 111 which engage under the shafts 105, the other ends of the levers being engaged by catches 115 on spring levers 116 pivoted at 118 and forming the armatures of electromagnets 117. When the latter are energized, the catches 115 are withdrawn, and pins 124 on lugs on the levers 116 engage projections 125 on the levers 111 and positively rock the totalizers to engage the differentials rack bars. The armatures are returned by their springs while a bar 130 cam-actuated from the main shaft 96 of the machine positively returns the totalizers bv projections 147 engaging the levers 111. This shaft 96 is driven through bevel gear from a shaft 53 which upon operation of the main handle is clutched to a worm wheel driven from the motor shaft and is given a complete turn during which the mechanisms of the machine pass through a cycle. The differential rack bars of like denomination are moved by shafts common thereto which are driven through clutches from the driving mechanism. The totals may be printed at any time by rotating a paper drum. by means of a handle, a wheel on the axle of the drum engaging a fixed rack and causing the drum to roll over the totalizers and print the record shown in Fig. 14. The strip 122, Fig. 13, is perforated by the machine from which the record is taken, such machine having three rows of punches, the strip being fed forward threefourths of the distance between two rows of punches at each operation of the machine. Perforations 303 in the row having twenty index positions represent the amount. A perforation 304 in the next row represents the clerk. A perforation 305 through any of the first six positions in the third row represents a department; a perforation 306. through the eighth, ninth or tenth positions in this row represents a cashier, while a perforation through the eleventh, twelfth, or thirteenth positions represents the class of transaction. The perforation 308 through the seventh position denotes the totalizer indicating the number of the machine and is the last perforation made. The rows of perforations representing the sales overlap and the three rows common to a sale are indicated by brackets. The punched record-roll is taken from the punching machine and placed on a spindle 323, Fig. 1B, from which it passes over guide rollers 314, 316 and table 315 to a storage roll 317. Pins 328 on two discs 329 co-operate with holes 330 near the edge of the strip and are driven through ratchet gear 336, 331, 338 from a cam-groove in a sleeve carried by the shaft 175 driven from and at the same speed as the shaft 53. Rollers 350 on spring arms 351 bear on the strip and prevent tearing of the paper. Slidably mounted in a box 357 having a top and bottom made of insulating material are three rows of pins corresponding to the rows of punchings. The box rests on the table and is supported by parallel links 360, 358. The box is raised by cam and link mechanism operated from the shaft 175 before the differential racks begin their return movement, and during this elevation the strip is fed. Near the end of a cycle, the box is lowered and the pins contact with the strip, the pins passing through where the paper is perforated. The table has contact plates as shown in plan in Fig. 15. The amount pins contact with the plates 366, the transaction pins with the plate 367, and all other pins with the plate 368. Fig. 15 shows diagrammatically how the various totalizer magnets are connected to the battery 85, contact pins, and contact plates. Two holes are punched to represent each digit in the amount, and commutator switches controlled by these punch holes determine the extent of movement of the differential rack bars. The magnets 117 of each of the first three rows corresponding to class of transaction have each one terminal connected to a brush contact 414 bearing on a shaft 412 having an insulated longitudinal strip. A brush 410 is connected to each transaction pin 356t while the other contact 411 is connected to the corresponding grand-totalizer magnet. The shafts 412 carry arms 417 and these are held as shown in Fig. 11 by the spring armatures of magnets 420. When switch 396 is closed and a transaction pin contacts with its plate the magnet 420 is energized and the arm 417 turns under its spring, the brushes 414 &c. being now in contact with the bar 412. A cam 436 on the shaft 53 operates a link 433 to restore the shaft. The switch 396 is closed once during the rotation of the shaft 53 by a cam. Specifications 17534/08 and 158,180 are referred to.
