Abstract: 767,284. Copying-telegraphy. ADDRESSOGRAPH - MULTIGRAPH CORPORATION. April 1, 1954 [April 8, 1953], No. 9571/54. Class 40 (3). Apparatus for reproducing on a copy strip, information carried by separate and discrete record members, e.g. business address cards, in which the records are passed at a constant, i.e. predetermined, rate to a scanning mechanism by a conveyer to which the cards are passed by feeding means and in which the copy strip is fed past the printing mechanism by further feed means, each of the feed means is driven from a main drive shaft and a change-speed mechanism is included between the main drive shaft and the first-named feed means to alter the rate of which the cards are fed to the conveyer. As shown, in Fig. 8, the scanning apparatus comprises a drum 20 with four helical slots scanning separate lines of the matter on the cards, and the reproduction is effected by four electromagnetic units 36 cooperating with a multi-turn helical ridge on a drum 35, the copy strip T and a carbon ribbon C being fed in combination past the drum 35 which, together with the drum 20, is driven by a motor M1. The strip T and ribbon C are drawn from the supply reels 30, 33 and pulled through the printing apparatus via guiding and idling rollers by means of take-up reels 31, 34 positively driven by a chain 73 from a wheel 74 on a shaft 75 carrying a wheel 76 meshing with wheel 88 on a shaft 130 carrying wormwheel 89 driven by worm 143 on the main shaft 140 driven from the motor M2. The strip T is also positively fed by a toothed drum 80 driven by the gear train 85, 86, 87 from the gear-wheel 88. The lowermost card of a stack of cards is inserted by feelers 103 between pairs of rollers 105 and transferred to a frame reciprocated by an arm 117. The card is thereby inserted between loops of conveyer belts 125 carried on pairs of rollers 126 and passed to a scanning position in relation to the drum 20. The rollers 126 are driven by gearwheels 128 and 129, the latter being on the shaft 130 carrying the gear-wheel 89 driven from the main shaft 140. The rollers 105 are driven from gears 110, 111, the latter meshing with gear-wheel 165 driven from gear 162 at the output of a change-speed device 160, the input of which is driven from shaft 140 by pulleys 145 and 147, shaft 150 and pulleys 156, 157. The gear-wheel 111 carries an eccentric crank 98 reciprocating an arm 99 secured to a shaft 100 which carries the arms 101 operating the feelers 103 and also a gear-wheel 102 meshing with a wheel 119 which rocks shaft 118 carrying the arm 117 by which a card is inserted between the loops of the conveyer belt. The changespeed device 160 may be continuously variable, or may be replaced by a gear train, Fig. 9 (not shown), in which two co-operating wheels in the train may be replaced by a pair having a different gear ratio. The associated pair of gear-wheels 76, 88 may be replaced by a pair having a different gear ratio in order to change the speed of the passage of the tapes T, C through the printing apparatus. The ribbon copy strip T may be replaced by a manifold copy strip which is normally held in folded form in a supply magazine and which, after the recording process, is fed to a magazine in which it is stored in folded form, Fig. 11 (not shown). Specifications 690,164, 693,576, 693,578 and 767,285 are referred to.
