Abstract: 799,011. Statistical apparatus. VEB BUROMASCHINENWERK KARL MARX-STADT. Feb. 8, 1955, No. 3748/55. Class 106 (1). A record card verifying machine comprises a card carriage controlled by a .magnet, a key-. board data setting means and an alarm means for indicating incorrect marking. The machine includes ten operating keys 22, Fig. 2, corresponding to the " 0 "-" 9 " index positions of a column of a record card, two operating keys 34 corresponding to the " 11 " and " 12 " index positions and a correcting key. The card is in a carriage which passes it column by column between a contact roller 21, and sensing members 20. Each key 22, 34 has an associated switch, one contact of which is connected to a line 30, the other contact of the switches of keys 22 being connected to a line 28 and the other contact of the switches of the keys 34 being connected to a line 37. Depression of a key 22 results in closing of switch contacts 24, 25, 26 and opening of switch 23. Depression of a key 34 results in opening of switch 19. In operation the card is tested column by column, skipping certain zones if desired. The operator depresses the keys 22, 34 corresponding to the data which each column should contain. If the card column is correctly marked a circuit is completed to the magnet 27 energization of which steps on the carriage to present the next card column to the sensing members 20. If any column is marked incorrectly a circuit is completed to a quick-acting relay A and to the glow lamp 31, relay A opens contacts a1, thus preventing operation of magnet 27 so locking the card carriage. If a column which should not be marked is marked a circuit is completed to relay A so that energization of magnet 27 is again prevented. If a column in a skipped zone is marked a circuit is completed to relay B and the glow lamp 31, relay B opens contact band so prevents energization of magnet 27. The record card is marked at each correct column as described later, by a ball-point pen recording mechanism. Keyboard construction and recording mechanism. Upon depression of a key 22, Fig. 3, an arm 39 is rocked counter-clockwise to move a slide 42 to the left, whereupon a pin 43 rocks a stirrup 45 counter-clockwise and a member 46 attached thereto raises bars 49, 50, 51, Fig. 5. The bar 51 is locked by detent 53 and angle levers 57, 57a are rocked to close the contacts 24, 25, 26, 29. Upon depression of a release key 62, Fig. 3, movement is transmitted via a rocker 64 and a bar 65 to the bar 51 which is rocked against the action of a spring 70 so as to be released from member 53, Fig. 5, angle lever 57 is released and contacts 29 open. The contacts 29 are also opened by movement of the armature 60 when magnet 27 is energized. On movement of the armature 60 a connecting rod 73, Fig. 3, is moved downwardly through the linkage 71, 72 and a rocker 74, Fig. 8, is moved counter-clockwise against a spring 83. A saddle 75 attached to the rocker 74 extends across the record card. A ball-point pen 92 is secured by a spring 98 to a member 91 carried by a lever 81 and having a slight pivotal movement with respect thereto. On the above counter-clockwise movement of the rocker 74 an arm 79 rocks the lever 81 counter-clockwise against a spring 85 and causes the pen to mark the record card. The pen 92 may be secured by a straight wire spring, Fig. 12c (not shown), or by a loop spring, Fig. 14 (not shown).
