Abstract

449,482. Feeding sheets. YAMAZAKI, K., 994, 2-chome, Higashi-machi Nagasaki, Toshima-ku, Tokio. Dec. 29, 1934, No. 37277. [Class 100 (i)] In connection with a mimeograph in which the printing frame 6 is lowered on to the top sheet of a pile to effect the printing, the printed sheets are automatically separated from the pile by means of a sliding friction pad 15 carried from a reciprocating block 3 by means of a lever 14, the block 3 being reciprocated by the movement of the frame 6 which is connected to the block 3 by means of a cord 41 passing over a pulley 5. A spring 8 and cord 4<11> return the block 3 and pad 15 to their initial position. When the frame is moved towards the pile for a further printing operation. The block 3 slides on a guide bar 2 provided at the front of the table supporting the pile, and is provided with arms 10 in which a lever 12 is pivoted, the lever 12 controlling the motion of the lever 14 which is also pivoted to the arms 10. The lever 14 is connected to a lever 13 which normally moves with the lever 12 owing to an adjustable spring connection 16, 71, 18 which causes the lever 13 to be depressed as the left end of lever 12 is raised by means of a sliding plate 20 which is operated by an adjustable camplate 25 with end ramps 24<1>, 24<11>. The cam engages a roller 21 on an arm 22 pivoted to the plate 20 and restrained by a pin as the block 3 is moved to the left by the opening of frame 6. When the pad 15 presses on the pile the lever 13 can move anticlockwise relatively to the lever 12. On further motion of the block 3 the pusher 15 moves the top sheet to the left into engagement with a conical roller 27 and two idler rollers 28 which complete the delivery of the printed sheets. The roller 22 is driven from the shaft of the pulley 5 by gearing including a one-way ballclutch. Sheet-holding devices 38, 39 prevent the sheets from rising with the frame 6, and a cam surface 44 attached to the block 3 lifts the holder 38 from the sheet during the separating action of the pusher 15. The holder is unaffected by the return motion of the block 3.
