Abstract

163,886. Stott, E., and Dawson & Sons (Otley), Ltd., W. April 20, 1920. Sheet-separators; dropping-roller and like sheet feeds; sheet guides and carriers. - Sheets are fed to printing and like machines from a pile by separating the top sheet by its front edge, raising said edge vertically or inclining it to the top of the pile, projecting a roller or the like beneath the raised sheet and the pile and bringing a further roller into contact with the proiected roller and feeding off the sheet by the revolving of these rollers. To assist in the feeding and separation of the top sheet, a stripping rod or tube may be moved over the top of pile between this .and the separated sheet. As shown in Fig. 3, the top sheet of a pile is separated by nozzles 12 on a suction tube 11 which is oscillated by rock ing arms 13 operated by levers 14 from cams 19 on a shaft 20. The arms 13 are moved to and from the pile by means of lever and link mechan. ism 21, 23, 24, 25 operated by cams 26 on the shaft 20. As shown in Fig. 3, the suction separator has raised the top sheet of a pile, and a stripper bar 28 carried by an endless chain 27 has moved under the top sheet, and it is carried by the chain across the pile to complete the separation of the sheet. The sheet is further separated and forwarded by means of sectional rollers 41, 49 which are mounted in oscillating levers 35, which are moved in a clockwise direction to bring the roller 41 under the separated sheet, the levers 48 of the top roller 49 being held by pawls 50, 51 away from the roller 41. When, however, the position shown in Fig. 3 is reached, a trip lever 52 trips the levers 48, and the rollers grip the separated sheet, and as the levers 35 move in an anti-clockwise direction, the rollers 41, 49 are rotated by a fixed rack 46 and gears 45, 44, 43 to move the sheet between guides 53, 54 to forwarding rollers 55, 56. In place of a bar 28 carried by endless chains, a reciprocating stripping plate or tube may be employed.
