of which theoliowing deseriptien, in eenv neetion with the accompanying drawing, is a specification, like eharaeters en the firmwlo ings representing like parts.

. This invention relates to improvements in tlre class of sheet feeding apperetns described in United 4States Paient No. 748,219, dated Eeeembe 29, 1903, the ebjeei o the present invention being to render easier and more certain the operation of the combing` wheel or other device in feeding the sheets continuously one after the other from the top of a pile of sheets, it being understood Ythat when a sheet. fails to be presented to the usual guides of the press to which Ythe sheets are supposed to be ed, the press will be stopped. V

In the patent referred te the sheets of the pile of sheets against which the combingwheel acts are maintained in a horizontal. positionY and considerable pressure ,is required to be exerted through the wheel so start the to -sheet `ef the pile, and with thin sheets t e pressure required for startm the top sheet 'from the pile of horizontal y laid sheets is suiiicient ai; times to in-Y jure and wrinkle the paper.

I have discovered by experiment that the sheets may he unerringly fedY from the pile by less pressure of the combing-Wheei on the: top-sheet of the pile, and without liability of injuring the-sheet, ii the support sustaining the pile of sheets is located in such 40 position that the sheets inciine forwardly and downwardly toward the inelined side of the ridge, as inse doing the tendency of each sheet to slide down and eff the pile is made evaiable to iessen the Yfrietiien to be overcome in startinfjeach from the top of the pile, and as sie friction of in@ most sheet en the sheet below it less electrieai influence is set np remevai of the successive sheets.

The drawing shows assueien portion of a sheet feeding apparatus, with my improvements added, te enable my inenien to be fzleseribedl The A' upperis reduced, dining the having the incline-df face e combing wheel 'A ere enti may be all as fully described in United Stetes--Peient-ele. 48,2i9, dated Beeeniher 29, 9E-3i In that ment ne ridge has e sioi i and'inimedieteiy below the apex ei the ridge i is jenrnaieri e reeir she 'te which is red en erin. 8 earrying e piae that. is yidingly snsreine in the sint o ehe ridge. rsfte eornbing wheel .acts on the tepY sheeef the i pileit projects said sheet orwardiyentii the front erige strikes the inelined snifeee oatiie ridge, said sheef; et this time being bent downwardly slightly by its own weight.l The veelfiiainned movement nf elle eombing wheei Y pushes the frentvedge of *tre sheeting@V the ineiined surface ei the ridge until aetai npon by the feeding wheei whieir operating Y in'conjunction withithe plate carried by the arms operates to feed the front portion of lthe ,sheet faster than 'the portion acted onby the eolnbing wheel whereby the sheet is straightened and lifted from the remaining sheets.

In the present appiicatien I employ es Vstated above the ridge heving the inclined facets, and I else employ the feeding wheel i 6 located above the peek of the ridge. In Iny presi-:ntL invention, iroweventhe erm 8 pivoted 'to the shaft 'i earri'esea relier l2 instead of the, plete above referred to, said miler receiving the ieee-ling edge oi 1the sheet on its way te be grasped by the feeding relier 6 whereby the sheet is acted npon and fed forward by 'the two roli-ers. Moreover in my invention the top of the support B sustaining the pile of sheets B is not arranged horizontally as previded i'or in said patent, i but is instead inclined downwardly inthe direction of the ridge plate, and the reside is L that the top sheet of the pile Qceupiese plane which inclines downwardly toward the inciined face a ef the ridge, the piene of the meets the face e etY e peint ediacent the lewer edgeY thereof. The restait of thiseensfruetien is that since the sheets eik oeenpy ein in# the top of the pilewhieh ere above the lower edge of theinelined snrfeee iisY 5o slide te: Y ward the eidge top sheet isircted upon by the combing wheei so that eiess amoent of rictierr is: :requiredV beiween the combing wheei and top sheel te effect theVA 'feeding ofthe sheets. Finether, es the sheets are projeeted' ferwendl, es shewn in the drawings, lthe 'ent edges iieree ,strike the inelineel i suriee e ofthe ridge at a aint nearer he bese than possible with t deviee shown top sheet having sneh en inclination that it i 10e I elined piane, the tendency 'ef those sheets at in the patent referred to above, and consequently as the front edges of the sheetsslide up the inclined face a of the ridge and are then grasped by the feeding wheel'6 more' room-is provided'for the various sheets to separateto permit air to enter between them. This results in eliminating to a great extent the tendency of the sheets to stick together and provides an Aapparatus by means of which the sheets can be more readily and acwith the device shown in the patent above referred to.

Having described my invention what I claim as new and desire to secure by Letters Patent' is 1. In an apparatus of the class described, a ridge havingan inclined surface, a support for a pile of sheets of paper having its top surface inclined downwardly toward the ridge, and a combing wheel to act on they up- `Y permost sheet of the pile and startit toward the ridge,the inclination of the support for the pile ofV sheets being such that the/tof support 'for a pile of sheets ofpapr, said its to occupying a plane insupport havin ly .an downwardly from a clined forwar horizontal plane, and a ,combing wheel acting upon tpe uppermost sheet of the "pile, vcombined""wi th an inclined :ridge and two rollers to which the end of the topmost sheet leaving the pile andr passing up the incline is delivered, the rotation of the wheels at the apex of the incline aiding Ain taking the topmost sheet rfrom the` top of the pile.

In testimony whereof, I have signed my name to this specification, in the presence o two subscribing witnesses.
