Patent GB-547565-A (GB)
Abstract: 547,565. Cash registers. NATIONAL REGISTRIERKASSEN AKT.-GES. Feb. 27, 1941, No, 2688. Convention date, Feb. 29, 1940. [Class 106 (i)]. In machines fitted with apparatus for issuing dividend, refund, rebate stamps, &c., an adjustment of certain parts adapted to the transactions to be carried out ensures that the total amount of stamps delivered together with a receipt check corresponds to the sum of the single purchases for which stamps are issued even when transactions not entitled to stamp issues are additionally recorded on the receipt check. The usual toothed segment 3 for each bank is displaced according to the value of the key 2 depressed in each bank. The segments are arranged on coaxial telescopic shafts 4. The movements of the segments 3 are transmitted by linkages 81, 4, 91 to the telescopic shafts 71, of a stamp-issuing mechanism. The part of the mechanism for the cent key bank will now be described the devices being similar for each bank. A rod 11<SP>1</SP> linked to a double lever 101 has an elongated slot in which slides a pin 12 of a toothed segment 13 carried on a pin 15 on a change-over lever 14 pivoted on the shaft 4. The lower end of the lever 14 is loop-shaped and co-operating therewith is a cam 22 on the drive shaft 19 of the stamp mechanism. The shaft 19 also carries a latch pawl 23 and a lever 20 a roller 21 of which co-operates with the segment 13. A roller 25 for each bank feeds a strip of stamps 32 and acts as a marking roller for the stamps to be cut off the strip. The roller 25 is driven by a toothed wheel 24 meshing with the toothed segment 13. A spring 41 tends to swing the segment 13 around its pin 15 to disengage it from the toothed wheel 24. The impression roller 26 may be moved away from the roller 25 against the influence of spring 29 to insert a strip by pressing down the arm 30. A knife 33 is operated to cut off the strip by a cam lever 23 engaging a pawl 33<SP>1</SP> connected to the knife by linkage 34, 25, the knife being returned by a spring 49. An arc-shaped lever 37 linked to a pin 38 and also connected by a rod 40 to a pin 39 of lever 14 carries a tooth 371 which locks wheel 24 as soon as segment 13 has been disengaged from the wheel 24 by spring 41. The machine is equipped with a change-over mechanism involving a drive from the shaft 181 to the shaft 19 including toothed gears and cam mechanisms so that the shaft 19 is not driven when certain control keys are depressed and thus no stamps are issued. Normally when for instance a key in the bank shown is depressed the sector 3 is positioned according to the value of the key. The levers 101 and 11<SP>1</SP> are also positioned according to value of the key. Upon operation of the machine by hand or by motor, the shaft 19 makes a revolution and as the cam 22 wipes around the inside of the loop, the lever 14 is rocked to disengage the sector 13 from the wheel 24, the sector being rocked by the spring 41 until the pin 12 engages the end of the slot in the lever 11<SP>1</SP>. During the last part of the revolution, the sector 13 is reengaged with the wheel 24 and is rocked by engagement of roller 21 with the tail piece to rotate the wheel 24 according to the value of the bank key depressed, when finally the pawl 331 is moved by the cam lever 23 to operate the knife 33. The Specification as open to inspection under Sect. 91 comprises also a modification in which the depressed key positions indicator tablets according to the value of the key depressed and a spring feeler lever adapted to engage the tablets co-operates with pawl and ratchet stop mechanisms to ensure feed and issue of the corresponding stamps on operation of the machine. This subject-matter does not appear in the Specification as accepted, but now forms the subject of Specification 549,667.
