Abstract
169,589. Mathes, A. Aug. 6, 1920. Cylinder machines; stencilling; tripping and like arrangements.-A machine for type or stencil printing comprises an inclined frame 2 in which is mounted type, or which can be fitted with a zinc-covered wooden frame when used for stencil printing. An impression roller 19 is mounted in adjustable spring-pressed bearings 18<a> carried by a pair of connecting-rods 15, at the outer ends of which bearing-rollers 14 are fixed which engage the undersides of rails 13 as the roller 19 is moved in an upward direction by crank-discs 31, connecting-rods 35, and links 16. The sheets are registered against front stops 24 on an adjustable frame 23 normally held raised by a cranked lever 27 operated on by a lever 30. which is on a shaft 29 controlled by a roller 37 on a lever arm and bv a cam 38 on the shaft 6 of the crank-disc 31. The stops 24 are depressed slightly from their normal position by the roller 19, and at the end of the upward travel of the roller 19, the cam 38 permits the stops to fall and the sheet is delivered in a downward direction. The rollers 14 return over bridge pieces 12 of the frame, and a new sheet is positioned against the stops 24 before the roller 19 reaches the full line position. The frame 2 is mounted in the main frame 1 by means of slots 3 which take over a rod 4, and by means of pivoted arms 7 with rollers 5 which rest on the shaft 6, the position of the frame being controlled by set-screws 11 in lugs 10 arranged to press on the rod 4 and on the arms 7. When printing from type, an ink cloth is arranged above the type carried by the frame 2. When it is desired to print from a waxed sheet or stencil, this is fixed in a frame 40 which is mounted in bearings 42 on the frame 1. Tllis frame is moved to and from the frame 2 by means of a lever 45 acted on by a cam 47 and the hard rubber roller 19 is replaced by a soft roller which receives ink from rollers not shown and acts both as an inking and impression roller.
