Abstract: 1330575 Selective punching apparatus J J MATCOVICH and J E MAGEE 24 Sept 1971 44702/71 Heading B4B Apparatus for successively recording a plurality of successive marks, e.g. punched holes or printed marks, in spaced positions on a record card, e.g. corresponding to the number of pins left standing after a ball has been rolled in a bowling game, comprises means for generating electrical signals representative of each of the marks, means, e.g. punches 74 responsive to the signals for punching holes corresponding to the signals and with a further hole indicating the generation of the signals and means 92 responsive to the presence of the further hole for producing relative stepping movement between the card and the punching means for thereby moving the card to a position for receiving holes corresponding to subsequent signals. The card is moved over a stationary tray 12 by means of a retainer 40 pivotally mounted in a carriage 42 which is slidable under the tray. The carriage is provided with teeth R1A to R10A and R1B to R10B adapted to be engaged by a pawl 100 pivotally mounted on an arm 98 actuated by a solenoid PWS; an escapement pawl 52 is also provided. The punches 74 are slidably mounted in plates 70, 72, Fig. 4 and 5, and effects a punching operation when a selected interposer 84 is moved by its solenoid IPS between the punch and a punch head 76. The punch head is moved downwardly by a solenoid PR5 via an arm 78. Each time the punch head is moved down, a further indexing punch 74a punches a hole in the card irespective of whether or not any of the punches 74 1 -74 10  have been selected. This punch is adapted to co-operate with a sensing plunger 92 which is raised and lowered by a solenoid SRS such that when the index hole is punched in the card, the plunger, upon actuation of the solenoid, passes through the hole thereby actuating a switch SM. In operation, a card 20 is placed on the tray 12 and retained by the retainer 40. The carriage is then pushed into the recorder against the action of the spring 58, the carriage being retained in its innermost position by the pawl 52, engaging the tooth R1A, Fig. 5. If upon rolling a ball no pins are knocked down signals are produced which via circuitry (Fig. 6) not shown cause the solenoids IPS to be energized so that the interposers 84 are moved over the punches. The solenoid SRS is also energized so that the sensing pin 92 is moved away from the card. The solenoid PRS is now energized so that the punch head 76 is moved downwardly to cause the punches to perforate the card. The index punch 74a is also actuated to punch a hole in the frame index column of the card (Fig. 2, not shown). Upon termination of the input signals (after about five seconds) the solenoids IPS and PRS are de-energized so as to cause the punches to be returned by springs 79. At this stage the solenoid SRS is again energized so that the pin 92 rises and passes through the hole in the card punched by the punch 74a and, in so doing, actuates the switch SM thereby energizing circuitry which de-energizes the solenoid SRS and energizes the feed solenoid PWS. The arm 98 then moves the pawl 100 so that the latter engages the pawl 52 causing it to disengage the tooth R1A and thereby allow the carriage to move one step and so position the second frame column marked on the card under the punches.
