Title: Improvements in and relating to calculating machines
IPC: G06C11/08
Filed: 1931-07-02
Abstract: 381,562. Punching mechanism for calculating machines. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. July 2, 1931, No. 19156. Convention date, July 7, 1930. [Class 31 (ii).] In a calculating machine the readings of the totalizer wheels are transmitted to another machine, a typewriter, or perforating mechanism by means of a set of electrical contact bars which are displaced simultaneously in accordance with the readings while the control of the other machine or mechanism is effected successively according to the denominational setting of the contacts. In Figs. 1 and 2 is shown the control for a perforating mechanism working on a code system with perforations representing the values 1, 2, 4, and 8. The number to be transmitted is carried by pinions 1 each of which is adapted to co-operata with a pinion 3 mounted on the armature of an electromagnet 6. Each pinion is biased to return to a zero position by a spring 5 and carries a stepped disc 12 adapted to be engaged by a finger 14 pivoted on an axis 13. The finger 14 is formed integral with an arm 15 having a slot engaging a pin 16 on a notched bar 16 adapted to co-operate with a set of contacts 201, 202, 20<4> and 20<8>. The contacts are normally held out of engagement with the notched bar 16 by a corresponding blocking bar 25 provided with notches a and controlled by a main operating shaft 30 through an arm 28 and one of a set of cam discs 31, 34, &c. On the shaft 30 is mounted a cam disc 40 operating a yoke member 35 which acts to release and eventually restore the notched bars for all denominations. When the electromagnets 6 are energized the pinions 3 engage the totalizer wheels 1 which are thereupon zeroized to transmit their setting to the stepped cams 12. The shaft 30 is then operated to free the notched bars which are displaced to an extent depending on the step of the cam engaged by the respective fingers 14, the contacts being closed in consecutive denominations successively by the release of the arms 28 seriatim through the cam discs 31, 34, &c. The electromagnets are de-energized to withdraw the pinions 3, but these are held in their set positions against the action of their springs by the engagement of the fingers 14 with the stepped discs 12 until the fingers are restored by the yoke 35. The closure of the contacts for each denomination effects the energization of corresponding electromagnets 41<1>, 41<2>, 414, 418, Fig. 2, to control, through their armatures, the operation of punches 43<1> .. 43<8>, to perforate a record card 45 in columns corresponding to the denominational values.
