Abstract: 1,202,057. Automatic sales accounting; counting-apparatus. DRESSER INDUSTRIES Inc. 18 Aug., 1967 [9 Sept., 1966], No. 38283/67. Headings G4D and G4T. A dispenser is provided with means for printing a record of the value and amount of fluid dispensed comprising a slidable drawer adapted to receive a ticket, a printing counter mounted within the drawer and driven by the dispenser, and a printing roller mounted adjacent the drawer and movable to press the ticket against the counter when the drawer is withdrawn from the dispenser at the end of a dispensing operation to print a record on the ticket. General.-A manifolding ticket 60 and credit card 58 are inserted in a drawer 14. The drawer is closed to unlatch a handle 110 which may be rotated to dispense fluid. Rotation of the handle moves a latch 118 into engagement with the drawer to prevent the drawer being pulled out during a dispensing operation. As the drawer nears its inner position, ticket 60 engages sensing levers 98 which move cam plates 80 forwardly to press an inked printing roller 50 against the ticket in preparation for printing when the drawer is pulled out. Volume shaft 24 and cost shaft 26 are driven by the dispenser to rotate the lowest order counter wheels 130a, 132a. After dispensing fluid, the lowest order counter wheels are justified, if they are in an intermediate position between two digits, and the counter wheels locked in position. When drawer is pulled out, the printing roller 50 is rotated by the drawer and a record taken from the credit card, raised indicia on the counter wheels 130, 132, and fixed printing surfaces 66, 68 displaying the date and unit cost of the fluid. As the drawer nears its fully open position, hooks 108 engage sensing levers 98 to retract earn plates 80 and raise the printing roller 50. Drawer 14 is pushed in to free resetting handle 112 which is rotated to zeroize the counters. Counters.-The counter wheels 130a-130d, and 132a-132d are mounted on shafts 142 and 144, respectively. Each counter wheel cooperates with a spring latch 162 mounted in a recess 164 in the shaft 142 or 144 and engaging a slot 168 in the counter wheel, Fig. 14. When the handle 110 is rotated a start shaft 38 is rotated to move a rack 188 downwardly. The rack rotates gears 180 to move the shafts 142, 144 longitudinally, disengaging the latches 162 from the counter wheels which are now free to rotate. Tens transfer mechanism 152 and spring fingers 156 are mounted on a carriage 154. During dispensing the carriage is moved to the right, Fig. 17, through shaft 38 and link 240, to place the tens transfer mechanism in engagement with the counter wheels. A slide 246 carrying fixed wedges 258 and spring-loaded movable wedges 252 is moved at the completion of a counting cycle to justify the lowest order counter wheels. On completion of the dispensing operation, shaft 38 is returned to its original position to disengage the tens transfer mechanism and move the shafts 142, 144 longitudinally in the reverse direction. Rotation of resetting handle 112 rotates shaft 40 to unlatch a spring motor 190. The latter rotates gears 194 on shafts 142, 144, whereby the shafts 142, 144 pick-up and rotate the counter wheels back to zero when the latches 162 engage slots 168. A flywheel 206 is driven by resetting movement of the shafts 142 and 144 to ensure correct resetting.
