To all 'wliom it may concern:

Be it known that I ALBURT DE PnJ-Auo, citizen of the United States, residing" at Cleveland, in the county of Cuyahoga and State of Ohio, have'invented certain new and useful Improvements in Paper-Feeding Machines,- of which'the following-is aspecification.

My invention relates to paper feeding machines, and the invention consists in a machine conspucted and adapted to operate substantialjy as shown and described and particularly pointed out inthe claim;

In the accompanying drawings,'Figure 1 is a plan view of the machine, and Fig. 2' is a side elevation thereof. Fig. 3 is' alongitudinal sectional elevation showing the feed rolls andthe lower sheet of paper in the changing position where the tucking or separating roll for. the paper has acted and the feed roll is in osition to carry the sheet forward, and Fig, 4" illustrates the further step wherein the feed roll has delivered the paper into the bite of the discharge roll and idler, all as will hereinafter fully a pear.

The machine as thus shown is a apted to feed single sheets of paper from. the bottom of a pile or stack of sheets indicated herein by P.

B represents a suitable bed or base covered in part by a plate A on which'the paper is laid and held in a straight block or stack from which the bottom sheet is separated downwardly and out as is usual in such machines. Said bed or base Bfhowever 0011-, structed otherwise, has an opening across its front or feeding end adapted to allow the sheets of paper as they are operated upon by the mechanism beneath to be handled by the rolls 0 and D and withdrawn from the ledge 2 at the front and tobe fed to the discharge rolls E and F as will presently be seen.

In the operation of the machine after a bundle or stackof paper has been properly positioned on plate A and base B it is necessary, first, to withdraw the bottom sheet from off the ledge 2 so as to get control thereof by the feed mechanism and deliver the same bodily and quickly from the pile to the use for which it is intended after it passes through rolls E and F. To this end the initial or tucking or separating roll C is provided :With a rubber or equivalent ad-v hesive strip 3. lengthwise on its surface to require. Thus it will be seen by the arrow thafi roll O has a reverse rotation turning over the top rearward and adapted'to withdraw the sheets ofpaper successively from ledge 2 and thus cause a slack or tuck to form therein behind said roll as seen in Fig. 3. The size ofsaid roll and the width of adhe'sive strip 3 are such as to make such withdrawal complete, as in Fig. 3, and wherein it is seen that said strip 3 has just done its work. This done forwardly rotating feed roll- D with its adhesive strip 4.- engages said sheet and projects it forward into the bite of rolls E and F which lie just to the front of said feed roll in right relation to receive the edge of sheet cZ.- As to the rolls C and D they are of the same size and have the same width 'of engaging'strips and the same relative throw by said strips respectively, one backward a given distance and the other forward the same distance and both rotate at the same speed but reversely. Hence being once set alight they must always work together inregular succession and without variance or failure.

The sheet d having been fed to the rolls E and F, it is withdrawn with a specially quick movement both because the operation of the machine requires this for clearance and because of the possible demand of the printing or other machines to which the sheets are supplied. To these ends theroll E is geared for speed as shall be seen, and the rolls or rollers F are idlers mounted on a shaft 0 which is suspended at its ends in ever, there are. moments when said rolls E and F are out of touch as'will-now be seen. Thus, the said shaft 7 has a lever or' arm :9 (see Fig. 1-): fixed on one end and pro- :vided' with a roller 10 at its side adapted to.

be engaged by a cam or rojection 11 fixed on the corresponding en of shaft 12 which carries roll D, orwhat may be the spindle of said'10ll. Assaid cam rotates it slightly depresses arm 9 against the Sustained action of spring 8 and lifts idler rolls F momentarily from the positive roll E. This is done to allow the edge of the sheet of paper to be thrust between said rolls as seen in Fig. Th as the said cam has passed said arm the idler F drops into engaging position and the high speed at which roll E is driven causes the sheet to be withdrawn in a sort of instantaneous movement and while both the rolls 0 and D are yet out of working relation with the paper. Of course as soon as said rolls 0 and D complete their rota.- tion another sheet is withdrawn and so on continuously. Hangers. 6 and arm 9 are rigid with-shaft 7.

Now, having reference to the driving mechanism for the several rolls, either hand or power may be used according to the size of the machine. In the present case the large drive gear G is shown as having a hand crank h, and said gear meshes with a pinion It mounted on a short shaft carrying ear and which meshes with. pinion 16 on shaft or trunnion 17 of roll E. Thus geared the speed of roll E obviously is greatly increased as compared with the source of rotation in gear G. On the other side the said drive gear G meshes with a gear 18 on the shaft 19 of roll. (l and which Sl'lttfl has a pinion 20 at its opposite end i'neshing with a like gear 21 on the shaft 12 of roll. D and of the same size in order to obta n uniform rotation of said rolls. If power were employed it:- wculd be applied by any suitable means to or in coi'inection with gear (it. Obviously, this transn'iitting mechanism may be mechanically varied or changed and the same results obtained in so far as operative effects are eonceri'ied. In this connection it will be seen that the bed plate A is provided with longitudinal slots (4 (see Fig. 1) adapted to afford longitudinal adjustment in respect to bed ll and. particularly to increase or diminish the space for the drop of too paper in the opening in said plate. as it comes behind roll {3 in order to tl(.C()lllll'l'l)(li\lL the machine to papers of dill'crent degrees of stillness or thict: as and to allow more orless room for sag or slack of the paper at that point xx. n withdrawn from ledge. 2 according to its quality or character in these particulars. This exceedingly in'iportcint in machines of this kind, and screws iii are shown to loch. plate in slots 0;.

it is especially to be noted here'n that all. are .ments of the operating part, are con- 2 tinuous in the same direction, and that all rolls rotate without cessation and at appointed speed. Furthermore, the slack producing roll 0 is arranged at the rear of roll D, which brings the initial forward feed roll D nearest to final feed r011 E. The gap between the last named rolls is thus reduced to a minimum, and therefore each sheet requires but a comparatively slight initial forward feed before being gripped by and between the more positive and faster final feed rolls E-F. Strips 3 and 4-may be of different widths to feed the bottom sheet different distances, either forward or backward. Obviously the throw forward must always be sufficient to enter the paper between rolls E and F.

Ledge 2 is shown in the drawings as having a beveled face 7) to direct the sheet downward if too stiff to flex and bend freely of its own accord and by its own weight. The upper face of this ledge is also preferably on a higher plane than the top surface of plate A, thus raising the pile at the front end of the sheets more than at plate A. Release of the paper-from ledge A and its discharge into rolls E and F is thereby'more freely and. surely effected. The difference in elevation between these resting parts for the paper relatively slight, but important, and though not-Iapparent to the eye in the drawings at first glance, it is nevertheless thus shown. i

"v "hat I claim is: v

A paper feeding machine having a bed for the paper provided with an opening in its front and bottom and a fixed transverse ledge at the front end of said bed at he edge oi said opening having an inclined deflecting edge for the paper, a rotatable separatin roll beneath said, opening adapted to eithdraw the lower sheet of paper baclc ward from said ledge, a feed-roll nextjn/ advance of said separating roll adapted to I rotate in the opposite d n :t'ion from said separating roll and carry the and a pair of dischai of said teed-roll ada 'itetfl to withdraw the sheetof papcrf edily fromthe machine, said feed-roll an l s sep: i.i.'ating roll each having adhesive strips engage the paper.

a. testnnony whereof I ailize my signature in presence of two witnesses.
