(ln the inner tare ot' the frame plate 1 is a :nain gear 10U el'iieh is designed to mesh with a suitable driving member (not shown) astior exainple. with a gear on one of the-drums 01 a rotary printing machine. 'llliis gear 100 meshes with :in idler 101 (Figs. i? and 8) ruhieh nieslies with another idler 1022 each on ,stads earried b v tlie fra'nie plate, and the idler 10?y nnxfilies with a gear 103 on a .shaft 101 mounted in the frame plate. On the eater end of this shaft 101 is a. pinion 10.3 niesl'iing with a large gear 10G', which is rigidly connected during operation (though adi? ably as hereiiiat'ter described) to the shaft .30. rrordingfly, Whenever the printing press is rotated, the shaft is rotated at a roi-res;ondig speed. 1t is to be linden stood that the diameter of the fading rollers 51 is; the pitch diameter of the gear 106, so that, the feeding action of 'these rollers is that of the printing mechanism. or other nnrhanisni, which receives the paper.

Though praurtire ixus demonstrutefl that my hiding inrclmuisni is very rei ain, re wiring in the regulur .feeding of but one sheet :1t u time, l 'consider it leso-:able to provide tlirow-out mechanism to stop the feeding operation in case two sheets are fed at once, since the feeding of two sheets results in a wasted sheet, in disturliin the count. und in throwing an unduly ieiwy impression on the printing mechanism. usmucli ns my mechanism is designed to he geured with u printing press, I proridc the actual stopping ineehnnisin 0:1 that press but ounect it electrically with the nutomutic rliuuusmt The result is that when the counter rollers on thesame shaft with the wiping fingers simplifies the construction and economizes space and lets the wiping fingers deliver the buckled portion oiV the sheet direetl \7 to the feed rollers. The wiping fingers and feed rollers and their shafts may be mounted in small` compass beneath the 'forward ends of a pile of pa.- per, and are thus outof the way. This dis position. of parts adapts the machine for ve"y convenient embodiment in a small device for .use in conjunction with an office printing press, if desired.
