Abstract: 751,945. Statistical apparatus. VEB BUROMASCHINENWERK KARL-MARXSTADT. Nov. 12, 1954, No. 32890/54. Class 106(1). An electromagnet 3 mounted on a frame 1 by an angle bracket 2 is energized by pulses from a known scanning arrangement (not shown). A yoke 4 with a stop 5 and an angle spring 6 is provided at its upper end with an angle bearing 7 for accommodating a connecting bolt 8. On the bolt 8 is mounted an armature 10 with release arm which is held in the position of rest by a spring 9. A spring pin 12 is fixed to the arrangement. On a shaft 13 extending the entire length of the machine is a drum 14 which moves anti-clockwise, Fig. 2, and bears control members 16 in slots 15. There is also provided a detent notch 17, a stop snout 18 and a spring hook 19 for attaching the tension spring 20. Electrical pulses are fed by a scanning device (not shown) through a pulse distributer to the magnets of the individual sorting compartments. As soon as the pulse reaches a magnet 3 the armature 10 mounted on the connecting bolt 8 is attracted. This clockwise movement is transmitted to the release arm 11 connected to magnet armature 10. Since the pulse distributer and the movement of the record cards runs synchronously with the drum 14 which rotates in anti-clockwise direction, a control member 16 is brought into the operative position through the movement of the release arm 11 in a clockwise direction. The control member 16 is pulled by spring 20 into the corresponding position 15 of the drum 14. On further movement of the drum the control member 16 is brought into contact with the surface 22 of the preselecting lever 26 which is rocked in a clockwise direction liberating lock pawl 33 by the pin 23. Further movement of the control member 16 causes control lever 27 to be rocked and lock pawl 33 is pulled by spring 38 against control lever 27. The arm 28 engages in the guide hole 41 of the disc 42 and rocks the disc 42 anticlockwise. The tension wire 43 connecting arm 39 to arm 44, Fig. 6, causes arm 44 to rock against spring 51 clockwise, thus bringing card-branch-off 45, 48, 49 into open position. If one pulse only is given the preselecting lever 26 is liberated and the cardbranch-off is closed. If successive pulses are fed to the same sorting compartment as the cards run through, the control member 16 is released as before but before it runs off the sensing face 22 of the preselecting lever 26 the next control member 16 has already run into the sensing surface 22 and the lock pawl 33 continues to hold control lever 27 in operative position. The guide pawl 86, Fig. 10, pressed by the tension spring 83 against the threaded spindle 74 is moved downward with the compartment floor 80 fastened to the sleeve 79 by the rotation of the threaded spindle 74 and the friction resulting from this pressure causes the snout 85 of the guide pawl 86 to remain in engagement with the thread. If a record card is sorted to the remainder compartment the control rocker 106, Fig. 16, is pressed downwards, when the card passes through and the lever 109 mounted on the bolt 107 is rocked in a clockwise direction. The connecting member 110 transmits the movement to the angle lever 112 and notch 113 which normally retains the control member 92 and which is now released. The operating member 92 displaces the threaded spindle 74 by an amount corresponding to the thickness of a card.
