Abstract: 372,742. Statistical machines. TAUSCHEK, G., 1, Meinhartsdorfergasse, Vienna. Dec. 2, 1930, No. 36294. Convention date, Dec. 3, 1929. [Class 106 (i).] A perforated record-card-controlled statistical machine having reading and counting mechanism therein, has removable additional counters externally of the machine, the cardreading mechanism controlling both the internal and the external removable counters. The additional counters are connected electrically to the machine proper and are fixed to a bracket on the outside of the machine. The invention is illustrated for use with Tauschek cards but may be adapted for Hollerith or Peirce cards. The cards are fed from magazine 1 by rollers 2 to brushes 5 connected by lines 6 to sockets 7. These sockets may be connected (1) by lines 12 to sockets 9 leading to the internal counter mechanism shown in Fig. 2 or (2) by lines 91 to the additional counters. There are sixty brushes 5 and seventy-five counter magnets 10 which latter may be split up to form a number of counters by disconnecting the tens transfer. (1) Adding and subtracting.-Internal counter devices. Each socket 9 is connected by a line 11 to a counter magnet 10. According to the number of holes in a card column the corresponding magnet is energized a corresponding number of times and through armature 13 and pawl 14 feeds a slide 15 the correct number of steps to the left. The slides are retained by pawls 42 which are subsequently removed, for restoring the racks, by rod 41 operated by linkage 40, 39, 38, Fig. 3, and cam 27 on disc 22. Attached to each slide is a U-shaped rack 16 which coacts with a gear wheel 17 on the corresponding counter wheel, the latter being frictionally mounted on its shaft. Just before the setting motion to the left, Fig. 2, of members 15, the upper racks 16 are engaged for addition. Each slide 15 carries a piece 23 which allows a stepped type-bar 18 to rise according to the amount the slide 15 is set to the left, the type-bars being controlled by a bail 20 actuated from cam disc 22. This sets the correct numbers at the printing line. The item having been added the upper racks 16 are then disengaged from the wheels 17 and the slides 15 are returned to the right. For subtraction, a lever 31, Fig. 3, is moved to the left so that just before the members 15 are set to the left by magnets 10, the lower racks 16 are engaged with wheels 17 and thereafter move the numeral wheels in the opposite direction to that for addition. The three positions of the racks 16 -upper or lower or neither racks engaging the wheels 17-are determined by bars 36 carried on a plate carrying a pivot pin 33, Fig. 3. A lever 29 has two slots 31<1>, 34<1> at right-angles to each other. Moving in slot 34<1> is a lever 31 pivoted at 33 and having a pin 32 which acts in slot 31<1>. When lever 29 is inclined as shown (up to the left) the top racks 16 engage the wheels 17 (adding position); with lever 29 horizontal, wheels 17 engage with neither the upper nor lower racks 16; with lever 29 inclined down to the left the lower racks engage wheels 17 (subtraction zeroizing position). Lever 29 moves on a fixed pivot 30 and is controlled by magnets 59, 84 and contacts 51. Transfer mechanism.-When a numeral wheel passes from 9 to 0 a lug 43 on it rocks a lever 44 counterclockwise, Figs. 2 and 9, so that an arm 45 is released and moved by a spring 47 to the right into contact with a pin 49 leading to the magnet 10 of next higher denomination. Subsequently a single impulse is transmitted over a common line 50 to springs 47, arms 45, and any contacting pin 49 so as to feed the higher wheel one step. The arms 45 are restored by a bail 55 actuated by links 52, 53, 54 and a cam 134, Fig. 3. Total-taking mechanism. - Total-taking is effected by reversing the switches 56, Fig. 1, and by placing an unperforated card on the table 4, Fig. 2. A pin 58 and pair of contacts 57 for each rack member 16 is connected to a switch 56. With slides 15 at zero, contacts 57 are closed. If any two switches 56 are shifted, all contacts 57 for columns between those switches are in series in the total-taking circuit. As there are no holes in the card on table 4 the circuit is thus closed through contact 57 to the total magnet 59, Fig. 3. When this magnet is energized, it coacts with cam 72 so that pawls 42 are latched up away from slides 15; lever 29 is positioned horizontally so that members 16 are moved to central position where neither upper nor lower racks engage the wheels 17 ; a zeroizing bar 78, Fig. 2, is moved into the path of lugs 43; the slides 15 are moved ten steps to the left; the lower racks 16 are then engaged with the wheels 17 and the counter wheels are moved on to zero (in the same direction as for adding) as the slides 15 return to the right. The pieces 23 are then set corresponding to the numbers which were in the counter and type-bars 18 are now raised and totals printed. After the type-bars have been restored downwards, the lower racks 16 are disengaged from wheels 17 and slides 15 are restored to the right by springs 125. (2) Additional removable counters. Seven additional counters mounted on the bracket A of the machine, Fig. 1, are connected by lines 91 to the plugboard 8, Figs. 1 and 7a. Fig. 7b shows the connections at one of the additional counters. The sockets 7, 9, 95, 94, 92, 93 of board 8 are connected as shown by wires 91a, 91b, 91c respectively to the sockets 96, 97, 98, 99, 100, 101 of the additional counter. By these means an internal counter and an external counter may, if desired, both accumulate from the same columns of the card. A switch 102 is controlled by a magnet 103 so that when the latter is energized, the switch is moved from the position shown to connect the sockets 96 to the lower socket of each pair of sockets a .. h. A similar switch 104 controlled by magnet 105 breaks the circuits to the tenstransfer contacts 107. When a card column is read by a brush 5 the circuit passes over a socket 7, line 91a, and socket 96 to switch 102 where it is divided. Part of the current flows through a plug 97 and wire 91b to a plug 9, Fig. 2, and on to a counter magnet 10. The other part of the current passes through switch 104 to one of the magnets 109 of the removable additional counters. This magnet, through armature 110 and pawl 111, Fig. 5, steps the counter wheel 112 on according to the number of holes read in the card column. Transfer mechanism.-When a numeral wheel of an external counter passes from 9 to 0 a lug 113 on it moves a member 114 to close the contacts 107, Figs. 5 and 7b. If the entry has been effected by card perforations, the magnet 105 is energized to move switch 104. This disconnects each counter magnet 109 from its plug 97 and connects it to the contacts 107 for the next lower denomination, whereby transfer is effected. Total-taking; zeroizing-mechanism; statistical cards.-As in the case of the internal counters a total-taking card with an unperforated column corresponding to the switch 56 which has been set, initiates total-printing. A second card, Fig. 8, with a hole 127 in advance of the card field is read by a special brush 5 which is connected to a plug 128, Fig. 7a. All such plugs 128 used are in series and are connected with the total magnets 59, 84, Fig. 3 ; plugs 128 are also connected by a line 126 to a magnet which completes the control of the total-taking circuit. Other columns of the second card, Fig. 8, have nine holes each therein to give the counter-wheel actuators the necessary number of impulses to zeroize all wheels. For manual zeroizing, a handle 118, Fig. 5, actuates catches 123 for all counter wheels, these catches engaging the lugs 113 to rotate the wheels to zero. Handle 118 moves approximately 120. The record cards may be replaced by perforated strips or plates. The electrical controlling devices above described may be replaced by equivalent mechanical means.
