PAPER-FEEDING-MACHINE ATTACHMENT.

Specification of Letters Patent.

yatented Dec. 22, 1908.

' r Application filed September 4, 1908. Serial No. 451,692.

county of Kings and State of New York,

have invented certain new and useful. Imf provements in Pa er,-Feedingl\lachine Attachments, of whic the following is a specification.

The resent invention relates to improvements in that classof machines which is designed to feed'successively. one sheet of paper at a time from a pile to a' printing press, paper folding or ruling machine, or other Inachin'es designed to operate upon paper.

More particularly, the invention relates to that class of feeding machines which carries a stack of sheets of paper or the like upon a substantially horizontal table, and from which the sheets are fed by the feeding mechanism unto the feed table.

In order to maintain and hold the other.

sheets of a ile in fixed and proper positions as the top seet is being so arated therefrom,

holders are provided usua y, which assure to some extent the separation of but a single sheet of paper from the pile by resting upon the sheets under the top sheet as the top sheet is being removed. Suchholders consisted, heretofore, usually of a single contact block, and it will be casily'seen that, when the sheets of paper'are held only at a single point, the same may be easily brought out of their proper positions by the sheet advancing means; for instance, the advancing means may, although not carrying the same in the direction of their own travel, force the sheets sideward. On the other hand, since the rear edges of the sheets of paper do not coincide as the same are combed, the contact block, heretofore in ,use, will from time to time allow two sheets to be fed unto the feeding table if not adjusted with particular accuracy.

It is now the object of the present'invention to provide means, whereby the aforesaid defects of the feeding machines are obviated.

To attain this end, the device consists of a plurality of fingers, engaging the stack of paper but caused to be disengaged with the same immediately before the top sheet is being removed;"as-now the top s eet is being advanced, the fingers engage in. succession the remaining sheets and always at the small est possible distance beyond the top sheet, whereby, first, the sheets under that top sheet are prevented in theirforward movement, and, second, their proper position is assured.

Other objects of the invention will be apc parent from a reading of the specification and an examination of the drawin s, forming p art of the present application for ette'rs'Patent.

The invention 1s illustrated in the accompanying drawings, in which Figure 1 is a side elevation of a paper feeding machine having'the attachment, forming the subject matter of the present application for Letters Patent, and Fig. 2 is a side elevation on line 2-2 of Fig. l, on an enlarged scale.

It will be observed that in Fig. 1- of the drawings only those parts of the feeding machine are shown which are necessary to understand the operation of the improved paper feeding device, which can obviously be attached to a paper feeding machine of any suitable construction, whereby the paper is being fed from a pile to a machine designed to operate upon paper.

In the drawings, 3 indicates one of a pair of the side parts of the frame of the feeding machine, and 4 one of a pair of the uprights, between which and the transverse vertical wall 5 of the frame of the machine is arranged in any suitable manner a vertically movable table (not shown in the drawings), carrying the stack of paper indicated at 6. The transverse vertical wall 5 is provided at its upper end with a forwardly bent lip 7, unto which the sheets are fed by a feeding means 8, actuated by the main shaft 9 of the apparatus, which main shaft is journaled in the side frame 3 and operated by any suitable source of power, for instance, by the intermediary of a chain 10, meshing with a sprocket wheel 11, mounted upon the main shaft 9. The mechanism for transmitting motion from the main shaft 9 to the feeding roller 8 is immaterial and is notvdescribed.

The sheets are fed from the forwardly bent lip 7 within reach of transporting rollers 12 and -13, and thus unto the feed band 14, which bring the same, in a well known manner, unto the cylinder of the press or to any other suitable apparatus or machine. The

' apparatus thus far described does not differ in any essential way from the feeding machines heretofore m use.

The paper retaining or holding device,

forming the subject matter of the present application for Letters Patent, is adjustably mounted on a bar 15, arranged arallel to the plane of the top sheet'of the p' e of-paper and at right angles to the main shaft 9 of the apparatus. This bar is mounted in the brackets 16 and 17, attached to the side frame3 and .the up ght 4,"reslpectively, and carries the frame..18 of the s eet retaining device,

1 which frame is provided with upwardly extending extensions 1:) and 20,' which engage {the-shaft 21, arranged parallel with the bar 15 and at right angles to the shaft 9. The

. shaft 21 is rotatably mounted in bearings 22 rprovided with a hole 26,.fitting the station-- and 23, carried by the-frame 3 and. the upright 4, respectively, and is provided at its inner end with a bevel gear 24-, in mesh with a similar gear 25, mounted upon the main shaft 9'. The purpose of this arrangement will be hereinafter'more fully described.

The frame of the paper retaining device is my bar 15 and allowing of a sliding movement of the frame relative to the bar,when

.it becomes necessaryto adjust the position.

of the frame upon said bar. serves to secure the frame upon the shaft in the desired adjusted position. The frame 18 is furthermore provided with a slot 28, at

right angles to the plane of the paper, covered by an upper plate 29 and a lower plate 30,

i suitably attached to said frame and provided with holes 31 and 3:2, res ectivcly, which holes are engaged by the ho ding or retaining fingers33. The fingers are slidably arranged in the plates 29 and 30, between which are arranged springs 34, each encircling one finger and bearing against the plate 29 and the lower enlarged end 35 of the fingers, tending tokeep thus said fingers in their lower positions. The lower end of the fingers may be provi ed with frictional shoes 36, made of resili t ate'rial, such as rubber. The upds df the --fingers are provided with flanges 37, limiting the downward movement of the fingers, which are pivotally connected with two-armed levers 38, carried by.

gfour'c'ams 41 mu t be provided. -These cams are arranged-on a sleeve 42, which is secured by means of a key 43 to the shaft 21.

lifted simultaneou'sly, but are brought in contact with the paper sheets'successively;

mentioned hereinbefore, the fingers are the cams 41 are, therefore, as shown in the A set screw 27 drawings provided with acting faces of different lengths.

The rearedge of the frame 18 is provided with a finger 44, contacting with the rear edges of the sheefii of paper and determining thereby the prdper position of the fingers 33 upon the machine.

The operation of the device is as follows: The main shaft 9 of the ap aratus operates the feeding means 8 and a so the retaining means or fingers 33 in unison motion. More articularly, the earns 41 shift the two-armed evers 38, whereby the fingers 33 are lifted against the tension of the springs 34, immediately before the feeding device 8 starts to, The top sheet is advance the top sheet. thereby free to move .forward. As shown in the drawings, the fingers I, II, III and IV are actuated by the cams I, II, III and IV,- respectivelyl As the sheet is moved by the feeding mechanism 8 toward the transporting rollers 12 and 13 and beyond the edge of the shoe 36 of the finger I, its corresponding roller 40 slides down the incline of the cam I, whereby its spring 34 causes the finger to contact with the sheet next to the top sheet, holding thereby thissheet from movement. As the top sheet is advanced further by the feeding means 8, the fingers II, III and IV are one after the other disengaged with their corresponding cams and brought by their respective sprin s in contact withthe sheet next to the top s eet. Attention is called to the fact that the cams are arranged upon the shaft 21 in such a manner, that the finger IV engages the sheet next to the top sheet immediately' before the top sheet comes within the reach of the transporting rollers 12 and 13. It-will be observed thatthus the sheets under the top sheet are'held at a plurality of points, maintaining and holding thereby-the same in a fixed and proper position and assuring thus practically the separation of but a single sheet of aper. If, however, the sheets are comber as shown in Fig. 1 of the drawings, 'each finger will hold one or more sheets under the top sheet in a fixed position, depending upon the relative position of said sheets.

Obviously, it will be necessary to adjust the positions of the cams and" the frame 18 upon the machine, as different sizes ofpaper are placed upon the paper carrying table. For this purpose the key seat 43 in the shaft 21 may be extended throughout the whole length of theshaft 21, or througha portion of four fihg'ers 33' the same according to the requirements.
