Abstract
217,283. Backhouse, H. T. March 6, 1923. Sheet - feed tables; dropping-roller feeds; sheet - registering devices.-A sheet-feeding mechanism of the kind in which the sheets are fed by hand from a feed table to a preliminary registering-device, from which they are fed automatically over a continuation feed - board or its equivalent to devices for registering the sheet laterally and longitudinally for seizure by the grippers or like members of a printing or other press is constructed as an attachment which can be applied to existing machines. A feed-table 6 is supported from the feed-board 4 of an existing machine, and is fitted at its front with an extension 8 over which the operator feeds the sheets to stops 17 mounted on an oscillating shaft 20 which is geared to a shaft 19 from which feed rollers 15 are supported. These rollers 15 are depressed to coact with a driven roller 9 as the stops 17 are raised to permit the advance of the sheets. The roller 9 drives endless tapes 12, and these tapes forward the sheets over a board 10 to the front stops 26 of impression cylinders. The sheets are registered laterally against a side stop 28 by a reciprocating pusher 27 operated by a cam 300, lever 31, and rod 32. The shaft 19 is also oscillated b the cam 300. The shaft of the roller 9 is driven from the printing machine by a shaft 30 acting through variable speed-gearing, which is arranged to slow down the sheets as they approach the stops 26. Sheet-carriers. - The sheets are preferably pressed on to the tapes 12 by means of anti-friction rollers 35 mounted in arms on U-shaped rods 37 carried on rods 38 supported bv a rod 39. The rods 37 are carried by sockets adjustable longitudinally of the rods 38, and are also laterally adjustable. Sheet guides and smoothers.-The sheets are guided to the stops 17 by guides 24, and may be acted on by smoothers as they pass over the board 10.
