Patent GB-360831-A (GB)
Abstract: 360,831. Ticket-printing machines. A. E. G.-FAHRKARTENDRUCKER GES., Hennigsdorf, Osthavelland, Germany. July 31, 1930, No. 2.3131. Convention date, Aug. 9, 1929. [Class 106 (iii).] A ticket-printing machine with adding mechanism for totalling the values of the tickets printed and with means for printing these values, is provided with a device controlled by the mechanism for printing the tickets, whereby on the printing of a ticket, when the means for printing the values are in the printing position, the means are moved out of that position to prevent fraud by blocking up the mechanism printing the totals on the adding mechanism. Rotation of the handle 1 in the direction of the arrow causes, through the cam plate 3 and rods 2a, 2b, movement of the cheeks 2 in the direction of the arrow X. The ends of the cheeks carry the printing platen 4 for the tickets and the adding mechanism which is thus moved to the right, causing, through the rack 6 connected by pins 5, moving in slots 17 in the wall of the adding mechanism, to an extension 18 of the printing machine, rotation of the toothed wheel 8 and actuation of the adding mechanism wheels 7 and corresponding type wheels 16. When it is desired to take an imprint of the type-wheels 16 a strip of paper is introduced through the opening 20 in front of the platen 12 and the lever 11 rotated to cause actuation of the lazytongs system 13, 14a, 14b and consequent pressing of the platen 12 and paper against the type-wheels 16, a pin 14 moving to the top of the slot 15 in the slide 9. If the adding mechanism were now in this printing position and the lever 1 were to be operated to print a ticket the consequent motion of the adding mechanism to the right with respect to the rack 6 would cause the lever 10 pivoted at 10a to the adding mechanism casing to pull down the slide 9 and with it the pin 14 to return the lazytongs system and lever 11 to their original positions and pull the platen 12 away from the type-wheels 16 which can thus rotate freely.
