Abstract: 941,261. Addressing-machines; copying documents. SCRIPTOMATIC Inc. May 25, 1960 [May 25, 1959], No. 18418/60. Headings B6C and B6D. [Also in Division B2] Apparatus for duplicating printed material from a master card to a workpiece comprises means to feed a workpiece along a straight path in a first predetermined plane, means to feed a master card along a path in a second predetermined plane parallel to said first plane and spaced therefrom, transfer means operable to move said master card perpendicularly to said second plane to a predetermined position adjacent the workpiece, and a pair of opposed rotatable rollers operable to engage the master card and workpiece at said predetermined position and feed them simultaneously along a predetermined path, said rollers also forcing the master card and workpiece into pressure applying engagement to duplicate the printed material on the card. Envelopes W, Figs. 17 and 23, are fed in succession over a table 103, Figs. 4, 17 and 23, between a moistening roller 110 and co-operating roller 111 and between pressure rollers 112, 113, to a hopper 157. Hectographic address cards C are fed in succession from the bottom of a stack by a stripper plate 51 secured to a feed plate 47 having a concave upper surface so as to support the stack of cards at their front and rear edges only, below adjustable gauge blocks 42, between rollers 68, 69, and between members 75, 76 having bevelled teeth to prevent return movement, into a chamber 74, where it rests on a table 78. Camactuated wires 82 rise through slots 79 to raise the card against an envelope, the card and envelope being passed together between the rollers 110, 111, 112, 113, there being provided openings 141, 142 in the table 103 in alignment with the rollers. The rollers consist of arcuate segments. The cards pass to a hopper 164. Each envelope actuates an arm 171 to close a switch 105, while the leading edge of each card actuates an arm 97 to close a switch 98. The switches 105, 98 when both closed actuate the envelope feed and operate a one-revolution clutch to actuate the wires 82 and the rollers. The envelopes may be fed manually. There may be provided sensing mechanism comprising two sensing switches 201, Figs. 20 and 22, adjustable along rods 202 and each having an arm 201a to sense a notch 200 in the address card in a particular position, while the card is on the table 78. The arm 201a if not in use is held behind a pin 207. There is provided a reversing switch which controls whether closing of a sensing switch causes printing or stripping of a particular card, and a four-position selector switch, which can be set to print (or strip) when the first sensing switch, both sensing switches, or either sensing switch, is or are closed, or to print from all the cards regardless of the sensing switches. For stripping, the electrical circuits are such as to operate the clutch but not the envelope feed. Damping copy-sheets.-Solvent in a container 115, Fig. 13, flows into a well 116 and thence by a flexible hose 118 to a supply tank 119, Figs. 13 and 23, which is open at the upper end and has a wick 121 immersed therein, projecting into contact with a capillary-grooved applicator roller 122 which engages an absorbent surface of the roller 110. The roller 122 and the tank 119 are carried by a yoke 124, Fig. 15, pivoted to fixed arms 125 of a bracket 126, a leg 127 of the yoke being positioned between cross arms 129, 130 of the bracket. A coil spring between the arm 130 and the leg forces the roller 122 into the path of the roller 110, this movement being limited by an adjusting bolt threaded through the arm 129 and engaging the leg 127. The tank 119 rests beneath a pair of retaining pins 134, Figs. 13 and 15, and is urged into engagement with the roller 110 by a leaf spring 135, the pressure being adjusted by a bolt extending through the yoke into engagement with the leaf spring.
