Patent GB-208431-A (GB)
Title: Improvements in or relating to rotary duplicators
IPC: B41L13/06
Filed: 1923-02-09
Abstract: 208,431. Ellam, F. Feb. 9, 1923. Stencillling ; tripping and like arrangements.-In rotary duplicators, that portion of the cylinder with which the paper first contacts is provided with a roughened surface to prevent slip and the forward end of the feed table is also roughened so that indiarubber discs which engage the top sheet of a pile and moves it lorward are prevented from moving when the pile is exhausted. The pressure roller is thereby prevented from being inked by moving against the cylinder. The cylinder is provided with a recess having a series of pins 12 for engagement by the perforations of the stencil 11, and mounted in guideways 14 is the roughened surface 15 of emery cloth or the like, which can be slide from the position shown in Fig. 2 to its operative position after the introduction of the stencil. The sheets are stacked on a table having gripping-devices 20 of known type and a gauge 22, one part 19 of the table being detachable and the other part 16 having a roughened surface. A reciprocating carriage 23 controlled by pairs of parallel links 27, 28 supports a pair of pivoted links 40 carrying a crossbar 42 with a series of india-rubber discs 43. The discs, which are prevented by a spring detent and ratchet from rotation in one direction, engage the uppermost sheet and feed it forward to the cylinder. Should there be no sheet left, the discs engage the roughened surface of the portion 16 of the table and the friction prevents the reciprocation of the carriage 23. For this purpose the carriage is made spring-actuated in the feeding direction by a spring 31 and bell-crank 30, and is positively returned by a cam 33 and thrust rod 36. A spring 39 returns the thrust rod, which is free to be moved up and down even when the carriage is arrested. The pressure roller 46 is passed by springs 50 toward the cylinder, and is kept from its operative position, unless a trip gear is operated by the reciprocating carriage, so that when there is no sheet in position the roller is not inked by the cylinder. A cam-operated thrust rod brings the pressure roller back from its operative position. Adjustment of the pressure roller is obtained by a hand-operated cam 53 acting on the leaf springs and controlled by ratchet and detent. Should the arms 40 which carry the cross bar and india-rubber discs be swung back to the inoperative position indicated in dotted lines, a handle 69 is raised and a projection 70 engages a stop 71 if the carriage be moved forwards. Instead of providing a roughened surface on the plate 15, the ink-carrying cloth, the cylinder itself, or the stencil may be provided with a roughened surface.
