PAlER-FEEDING DEVICE.

To all who/m it may concern:

Be it known that l, HARRY C. Garratn'rnn, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new; and useful Improvement in Paper-Feeding Devices, of which the following is a fnll, clear, and exact description, reference being had to the accompanying drawings.

The object of this invention is to provide a simple attachment for printing machines to enable the paper to be fed thereto very rapidly in single sheets.

The invention is well adapted for use with a hand operated rotary printing mechanism of the type known commercially as the multigraph.

The invention comprises essentially an adjustable clamp and guiding members so arranged as to hold the paper so that it may be conveniently shoved forward en masse until the top sheet is released and then that sheet fed to the machine.

The invention is more particularly hereinafter described and its essential characteristics are set out in the claims.

In the drawings, Figure 1 is a sectional side elevation of a multi graph equipped with mypaper feeding device; Fig. 2 is a section through. the paper feeding device proper; Fig. 3 is a perspective of such feeding device; is a cross section on the line 4-4 of Fig. 3, and Fig. Iis a section similar to Fig. 2 but showing a modified form of paper supporting saddle.

Fig. 1 shows a printing drum 5 having longitudinal channels 6 adapted to carry type, there being a rotary impression platen S-and 9 designate paper feed rolls which are adapted to vgrasp asneet of paper and feed it between th'e roller 1.0 4and the impression platen when the feed .rolls are revolving. This revolution taires place at the proper-time by reason of a segmental rack 11 on the printing drum engaging a pinion 'l2 which meshes with a gear 13 on the feed roll 8. The machine thus described is that shown in 'Patent No. 812,735 granted Feb. 13, 1906 to ll. C. 4Gammeter. As shown in that patent, there is a table 15 on which the paper to be y:printed lies, it being shoved forward by hand into the grasp of the rolls 8 and 9.

Practice has demonstrated that it is difli- Speeication of Letters Patent. Fatentd July 25, 1911,

cult to feed the 1p time, and to enab e this to be done, l have devised the attachment which is the subject of this invention, this attachment .being adapted to rest on and be removably .carried by the table 15. 4 As shown, my attachment comprises a sheet metal base 2O having one upturned guiding edge 21. The other guiding wall 22 is a separate sheet of metal which has its lower portion hanged first inwardly at 23, and then out- 6E:

wardly, at 24, to make a suitable stiff supportfor the wall. Through-the outward extension 24 of this ange are clamping screws 25 which pass through slots 26 inthe base 20,

whereby the wall 22 may beadjusted in or 7u^` i out and clamped in desired position. Tles clamping screws may pass through slots in the table 15 and form also the means 'for holding my attachment to the table. 'the` inner ends of the walls 21 and 22 are prefl '35 erablyturned over, as shown at 28 and 29 to insure the paper being held down on the f plate.

The adjustably positioned clamping 'del y vice for the paper comprises parts carried by a bar 30 slidably mounted'on theplat'e 20 by extending beneath"lu`gs'31 turned'npi ward from the. plate.' At its v,outer end this bar is turned backward toward itself in a.

Usshape as shown at 33 and at the extreme 85 left of this U is fastened a steel spring or clip 34;. The inner end of the spring or clip .is g bent downwardly, as shown at 35, and tends to bear against a curved saddle mounted on the bar, being either a curved plate 36 se# 90 cured thereto (as by lugs37 occupying recesses in the bar) or a roller 36a carried by the bar, as shown in Fig. l

The several sheets of paper before they are placed in the feeding device are fanned out by being bent back and forth to cause each sheetto slightly overhang the-one below it, and then the spring 34 is raised and paper placed between the end 35 and the saddle 3G, with the top sheet extending only slightly 100 beneath the spring. New in the operation of the printing mechanism, the paper is pe-n riodically shoved forward by suitable means, which may be the hand of the operator;

The friction between the'ditferent sheets of 105 paper being greater than that between the paper and the smooth saddle and the springv 35, the whole pile of paperfeeds forward as' aper rapidly a sheet at a 55 a unit until the top sheet passes from beneath spring 34. Thereupon this top sheet being free is alone fed forward by a continuation of the same pushing action which shoves forward the whole pile, the spring holding all the other sheets. This movement takes place for each forward pressure on the paper. For each sheet the whole pile of paper,

cluding means for holding paper at the' clamp out of engagement with the main paper support. l
