Abstract: 317,062. Hasler Akt.-Ges. vorm. Telegraphenwerkstatte von G. Hasler. Aug. 9, 1928, [Convention date]. Counters with recording - apparatus; printing subtotals; stop-mechanism. - In a controlling or checking device for value-stamping machines provided with . counting mechanism, wherein the state of the counter is impressed upon a record card when the card is changed, the holder of the card is displaceable tangentially of the type-wheels by a device actuated to effect the card changing, by which device the card is impressed in one position of the card holder at the beginning of a counting period and in the other position at the end of the counting period, so that the card exhibits two different sets of numerals one above the other, the difference between the sets corresponding to the amount counted during the period the card has been in the machine. In franking-machines, a stopmechanism is provided to lock the counter and permit the removal of the card after a predetermined increase in the amount counted. In cash registers, this mechanism is omitted to allow removal of the card for example upon change of the clerk in charge. As shown in plan in Fig. 2 and end elevation in Fig. 3, the device is applied to a franking-machine and comprises a cardholder 5 disposed parallel to the type-wheels 2 of a counter and guided for vertical displacement in plates 7. The card 4 is insertable into and removable from the holder 5 through a slot 30 in the casing, only when the holder is in the lower position in which position it is maintained against the upward action of spring-urged arms 10, 11 by means of interconnected levers 48, 53 engaging slots in downward projections 8 of the holder. The initial impression is effected by movement of an impression roller 17 from left to right, Fig. 2, by the manual rotation of a screwthreaded spindle 15. At the right-hand end of its travel, the roller support trips the lever 48, and the holder thereby released moves to its upper position. The movement of the lever 48 allows a rod 46, engaging a hole in the rearward end of the lever, to pass through a flared hole in a second lever 49, the resulting rocking of which unlocks the machine, but locks the spindle 15 by interposing the forward end of the lever into the path of a stud 56 thereon. When the allowable amount has been added into the counter, the type-wheel corresponding to the maximum digit actuates a wheel 41 that, through shaft 40, star wheel 42, lever 43, shaft 44 and lever 45, lifts the rod 46 to release the lever 49 and thereby lock the machine and release the spindle 15. The final impression of the card is effected in a position below the initial impression by a. reverse rotation of the spindle. At the left-hand end of its travel, the roller-support returns the cardholder to its lower position by engagement with a cam-shaped projection 31 on the arm 10, the cards are consecutively numbered by an auxiliary counter 38, 39 actuated from the card holder through a pawl 36 and ratchet-wheel 37. The number of the machine is impressed on the card at the initial impression only, by means of a stamp that is vertically guided on a frame member 1 and moves with the card-holder.
