Abstract: 444,033. Calculating-apparatus. NATANDERER-WERKE VORM. WINKL-HOFER & JAENICKE AKT.-GES., Sch÷nau, Chemnitz, Germany. Sept. 18, 1934, No. 26787. Convention date, Sept. 18, 1933. [Class 106 (i)] In a machine provided with a plurality of totalizers and with a travelling paper carriage selection of a totalizer is effected automatically under paper carriage control or manually by the setting of selector means and in such a manner that the selection by the manual set means renders the automatic control means inoperative. An electrical selector mechanism for nine totalizers is shown diagrammatically in Fig. 1. The mechanism comprises a bank of selector keys 1a .... 1i, carriage controlled contacts 38a ... 38i a set of solenoids 11a ... 11i, and electrical circuits connected to supply leads 22, 23. A switch 24 closed at a determined time in the cycle of operation allows current to flow to a conductor 40 through one of the solenoids and either through the corresponding closed contacts 38, conductor 39, and switch 25 and switch 244 or through one of the contacts 2a .... 2i of the selector keys and the return conductor 42, and switch 25, to the line '23. When a selector key is depressed the detent bar 41 is moved and the switch 25 is thrown over to a position other than that shown in Fig. 1 thereby disconnecting the conductor 39 and rendering the carriage contacts inoperative. In any particular carriage position a particular totalizer may be selected for additive items and another one for subtractive items. As shown in Fig. 1 the totalizers associated with the solenoids 11a ... 11d are arranged in two groups by providing parallel connections 18ab, and 18cd. These groups are disconnected from the conductor 40 by switch connections 12a .... 12d and the solenoids are connected by switches 14a .... 14d to a change over switch 46 operated by a subtract lever 44. By closing the connections 12a .....12d and opening the connections 14a ... 14d, and 18ab, 18cd the group selection may be rendered inoperative. Key selection of the grouped totalizers is prevented by displacing the corresponding key contacts 2a ... 2d. The other contacts may be rotated singly or as a whole to prevent key selection or the keys may be rendered inoperative by shifting the switch 244. Electrical connections. In a constructional form of apparatus wherein eighteen totalizers are mounted on a stationary drum the conductors leading from the key contacts and from the carriage contacts as shown in Figs. 2, 3, are mounted on rings 200, 201 of insulating material being connected to metal heels 202, 203 threaded on studs 206 attached to a carrier plate 207 of insulating material and are easily removable as a unit. The plate 207 and a distance annular insulating ring 214 carries the frames 213 of the solenoids, the coil windings being connected at one end to a common bus-bar 219 and individually connected at the other end to a terminal 221, the whole forming a removable unit. In order to select totalizers according to positive and negative amounts a switch, Figs. 19 and 20 is provided ; the leads 13a ... 13d from the contacts of switch 46 are connected to terminals 14a ... 14d having leads 15a ... 15d that are connected to other terminals 16a ... 16d mounted on contact members 219a ... 219d forming extensions of a bus - bar 219. The last mentioned contact members are each connected to one end of the winding of a solenoid the other end of the wire being attached to a terminal 221. In place of the bolts 206 longer bolts 382 are substituted which have connections to the rings 200, 201 that are connected by leads to the key and carriage contacts and carry in addition contact plates 17a .... 17d. The terminals 14a ... 14d and two plates 18ab, 18cd are mounted on a disc 387 of insulating material and provided with a sleeve 386 rotatably mounted on a bolt 385 secured to a fixed insulating plate 384. A disc 388 integral with the disc 387 carries the terminals 16a ... 16d. A notch in the disc 387 cooperates with a pin 390 on the plate 384 to permit a limited rotation thereof. In the position shown in Fig. 20 the plates 18ab, 18cd form parallel connections to the solenoids lla ... 11d in pairs. In the addition position of the switch 46 the solenoids 11b, 11d can be selected for positive amounts. Totalizer engaging mechanism. In one form of machine a fixed drum is shown provided with eighteen totalizers 50, Figs. 5, and 13 with shafts 51 carrying guide members 49 movable in radial slots in side plates 53, 54 the shafts being urged away from the centre by springs 55 to maintain the totalizer pinions 58 in engagement with aligning bails 59. The pinions 58 of each totalizer are moved into engagement with their differential actuating gear wheels 60 by means of a corresponding pair of arms 62, 63 on a spring controlled shaft 64 the arms having cam shaped ends engaging rollers 66 on the totalizer shaft 51. The actuator gears 60 alternate with transfer actuating wheels 61 and are loosely mounted on a sleeve 195, Fig. 8, secured to side plates 196, 197 and carried on a shaft the whole forming a removable unit. When a solenoid is energized to select the appropriate totalizer its armature displaces a spring controlled coupling pin 73 carried by the arms 62, 63 so as to project its end into the corresponding hole of an actuator plate 67, Fig. 7, rockable in timed relation with the actuator gears by means operatively connected to the main shaft of the machine. The main shaft is connected to one end of a thrust rod 76 the other end of which is pivoted to a disc 77 on a stud 78. During the first half of the cycle of operation in addition the disc 77 is rotated clockwise whereby a pin 90 passes by a notch 91 in a pawl 87 pivotally mounted on a slide plate 82. At the beginning of the return movement the pin bears in the notch and the slide plate is displaced to the right being held in its displaced position by a locking pawl 92 engaging a projection 99 on the plate. During this movement a roller 100 on the plate rocks a cam plate 101 which, through a double armed lever 103 and link 106, imparts an angular movement to the actuator plate 67. At the end of the return movement a hump 97 on the disc 77 releases the locking pawl 92 and the plate 82 returns to normal position under the control of a brake cylinder or dashpot 108. The cylinder 108 has a needle valve 109 the opening of which can be controlled to wholly or partly annul the braking effect. The drive of the differential actuators is obtained from the rack sectors 161 that mesh with the type bars 160 ; these type bars are connected at their lower ends by yielding means with racks 162 geared to the actuators. Transfer mechanism.-Each pinion 58 of the totalizer has a transfer tooth 166, Fig. 4, adapted to co-operate with corresponding teeth 167 of a transfer wheel 61. Each wheel 61 has a set of teeth 168, Fig. 5, thereon engaging similar teeth on the arm 169 of a three armed lever 170. At transfer when a wheel 61 is displaced the lever 170 is rocked against the action of a spring 173 and'the arm 171 is moved out of the path of a projection 181 on the rack 162 of next higher denomination so that an additional step movement is permitted by the yielding connection 163, 164. The lever 170 is held in its displaced position by a latch 176 which is adapted to be released, to allow the parts to return to normal position, by the operation of a flat sided shaft 180. This restoration is effected on the next succeeding cycle by a pin 152 on the disc 77, Fig. 7, rocking a lever 186 that is connected by a link 188 to an arm on the shaft 180. Non-add control. To prevent engagement of a totalizer during either half of the cycle of operation a stop roll 111, Fig. 7, on the paper carriage rocks a lever 112 and through a link 115 rotates a member 116 pin and slot connected to a link 120. When this link is moved it rocks a lever 122 and displaces a Jink 126 the end of which by engagement with a pin 129 on the pawl 87 moves the pawl to inoperative position so that the side plate 82 is not reciprocated. The member 116 is also connected by a link 156 to a non- add key (not shown). Total and sub-total taking mechanism. By depression a total key (not shown) a slide 135 is moved longitudinally to its fullest extent and a projection 140 thereon moves away from a pin on a pawl 132 pivoted on the plate 82 whereby the pawl is rotated about its pivot into the path of a pin 130 on the disc 77. At the same time a pin 143 on the slide 135 rocks the lever 122 to render the pawl 87 inoperative and by engagement with a pin 95 on the locking pawl 92 throws this pawl to inoperative position. When the disc 77 commences to rotate the pin 130 pushes the pawl 132 and plate 82 to the right to move the selected totalizer to engaged position ; at the end of this forward movement the pin passes the pawl 132 and the plate 82 springs back to normal to disengage the totalizer. For this purpose the action of the brake device 108 is annulled by a lever 144 acting on the needle valve 109, the lever being rocked on displacement of the slide 135 by its forked end embracing a pin 145 on the slide. During the total taking operation the slide 135 is held in set position by a latch 146 engaging a projection 153. Normally the latch 146 is inoperative by reason of its connection with a lever 150 engaging a pin 152 on the disc 77 when in its normal position. In taking sub-totals depression of the subtotal key gives half the full displacement to the slide 135 and during the operation is held by the latch 146 co-operating with a projection 194. By this setting, the pawl 132 is rendered operative, the pin 143 is not moved sufficiently to rock the lever 122 so that the locking pawl 92 also remains in effective locking position, the lever 144 swings idly permitting the brake cylinder 108 to function. The totalizer thus remains in engaged position during the forward and b
