A TTORNEYS E 771, fanfare Patented Jan. 24, 1933 UNITED STATES PATENT OFFICE RAY M. FENTON, OF YOUNGSTOWN, OHIO, ASSIGNOR TO THE NEWTON STEEL COMPANY, OF YOUNGSTOWN, OHIO, A CORPORATION OF OHIO SHEET FEEDING APPARATUS Application filed .Tune 29, 1930. Serial No. 463,073.

This invention relating as indicated to sheet feeding apparatus, has particular reference to an apparatus adapted to be em ployed for the purpose of feeding sheets to cold rolls and the like during one step of the treatment of such sheets in the course of their manufacture. Considerable difliculty has been experienced heretofore infeeding sheets especially in packs to rolls due to the fact that no means has been provided for positively aligning the sheets with respect to each other as well as with respectto the rolls to which they are fed. By employing the mechanism comprising my invention the sheets may be fed to the rolls in such a manner that lateral alignment of the sheets is positively insured with respect to each other and with respect to the rolls,-and also this mechanism is adapted to be adjusted so that, as occasion may demand, the sheets may be fed to such rolls in any one of a number of'relative lateral positions. Other objects of this invention will appear as the description proceeds. To the accomplishment of the foregoing and related ends, said invention, then, consists of the means hereinafter fully described and particularly pointed out in the claims.

The annexed drawings and the following description set forth in detail certain mechanism embodying the invention, such disclosed means constituting, however, but one of various mechanical forms in which the principle of the invention may be used.

In said annexed drawings: Fig. 1 is a side elevational view of the apparatus comprising my invention; Fig. 2 is a plan view thereof; Fig. 3 is an end elevational view thereof; Fig. 4 is a part sectional, part elevational view of the rolls and associated housing members to which the sheets are adapted to be fed by the apparatus comprising my invention; Fig. 5 is a fragmentary elevational view of one terminal of the carriage supporting tracks showing the carriage stop member associated therewith; and

Fig. 6 is an end elevational view of the structure illustrated in Fig. 5.

Referring more specifically to the drawings and more especially to Figs. 1 and 2,

the apparatus comprising my invention is shown associated with vertically aligned rollsfl and? which have their necks 3 and 4 respectively journaled in bearing blocks 5 and Gpro'vided therefor. The bearing blocks 5 whichrotatably support the lower rolls. 1 are positioned between the spaced housing members'7 and 8 which may have guide ways formed on the opposed faces thereof adapted to slidably engage the bearing block 6 in which the upper roll 2 is journaled. Contact between the rolls land 2 is insured by compression springs 9, the pressure exerted thereby being regulatable by means of screws 10 which, at their lower terminals, contact with plates 11 and which are locked in position by nuts 12. The lower roll 1 has a sprocket 13 secured to one projecting terminal thereof and the opposite'terminal of such roll is provided with a pinion 14 which meshes with a pinion 15 secured to the upper roll whereby driving communication is established from such lower roll 1 to the upper roll 2. The housings for the rolls 1 and 2 are preferably bolted or otherwise secured to sills 16 which may be mounted on suitable pillars such as 17.

The sill 16* may have framed thereto-transversely extending members 18 which serve as a means of support for track rails 19. The track rails 19 are longitudinally inclined as most clearly indicated in Fig. 1, such inclination being preferably away from the rolls 1 and 2.

Movably mounted on the track members 19 is a carriage which has a substantially fiat bed 20 to which is secured depending bracket membors'21 which serve as a means of support for pins 22 which pass thcrethrough and on which are j ournaled wheels 23 which support the carriage. The track members 19 have associated therewith at their terminals stop members 24 which are secured thereto in the manner most clearly illustrated in Figs. 5 and 6 and which have concave faces 25 preferably of a curvature or radius equal to the radius of the wheels 23. The stops 24 prevent the carriage from running off from the track on the rear end thereof due to the slope of such track and prevent such carriage from being pulled off from the front end thereof as the sheets positioned on such carriage are drawn throughthe rolls 1 and 2. J ournal'blocks 26 mounted on the sill member 16 adjacent the carriage and journal blocks 27 mounted on the cross members 18 have journaled therein shafts 28 which are threaded as at 29 throughout the portion thereof between such journal blocks. One of the shafts 28 has a hand wheel 30 secured thereto for the purpose of the manual operation thereof and.

both such shafts have sprockets 31 secured.

feeding apparatus may be briefly described as follows. After the rolls 1 and 2 have been usted relatively to each other by means of the screws 10, a pack of sheets or a single sheet is placed on the bed 20 of the table, the operators pushing such sheet or sheets laterally until the edges thereof contact with the vertical guide member 34. Afteror during such alignment of the sheets against such guide member, the sheets and the carriage on which the sheets are supported is pushed forwardly up the, inclined track 19 until the forward end of the sheet or sheets is enga ed by the rolls 1 and 2, As the sheets are pus ed forwardly toward the rolls, the stationary guide member 34 which has been adjusted previously laterally with respect to the track 19 so as to insure the proper alignment of the sheets entering the rolls, serves as a means for bringing to a common plane, the edges of all of the sheets on the bed 20 of the table. By employing the mechanism just described, it will be noted that the proper alignment of the sheets relative to. each other and to the rolls is accomplished'easily and practically automatically as such sheets are fed to the rolls. The lateral adjustment of the stop 34 enables such stock to be properly positioned so that the sheets will enter the rolls at the proper position relative to the sides or rough portions of such rolls. This lateral adjustment of the stop 34 is particularly advantageous from the standpoint'of enabling the operators to feed the sheets to the rolls in such a manner that the smooth or unbroken body portions thereof will at all times be fed to the smooth or polished central portions of the rolls. In this manner all marking of the sheets is avoided which would occur if the sheets were not accuratel aligned and prop erly fed to the rolls. T e adjusting screws 10 whereby the pressure between the rolls on their opposite ends may be regulated are also capable ofbeing employed for the purpose of insurin the proper lineal passage of the sheets through the rolls. By maintaining the screws 10 in proper adjusted position so that the pressure between the rolls on their'o posite ends is the same, the sheet or sheets w 'ch are, pulled through the rolls will so passbetween the housings without pulling to one side, which usually results in a marking of the sheets.

Other modes of applying the principle of my invention may be employed instead ofthe one explained, change being made as regards the mechanism herein disclosed, provided the means stated by any of the following claims or the e uivalent'of such stated means be employ I therefore particularly point out and distinctly claim as my invention:

1. In combination with rolls for sheets, of a movable carriage for feeding such sheets to such rolls, a longitudinally inclined track sloping away from such rolls supporting said carriage, a stop extending longitudinally and along one side only of said track adapted to engage the edges of such sheets, and means for moving said stop laterally relative to said track.

2. In combination with rolls for sheets, of a movable carriage for supporting such sheets and feeding the same to such rolls, a longitudinall inclined tracksloping away from such ro is for supporting said carriage, stops associated with said track for limiting the longitudinal travel of said carriage, a

uide' for said sheets extending longitudinaly and along one side only of said track normal to the bed of said carriage, and means for moving said guide laterally relative to said track. a

3. In combination with rolls for sheets, of a. movable carriage for supporting such sheets and presenting the same to such rolls, a longitudinally inclined track sloping away from said rolls for supporting said carriage,

y of said track normal to t o bed of said carriage, and means for moving said guide laterally relative to said track.

4. In combination with rolls for sheets; of a movable carriage for supportin such sheets and presenting the same to sue rolls;

a longitudinally inclined track sloping away from such rolls for supporting said carriage; stops associated with said track limiting the travel of said carriage; a guide for the edge of such sheets extending lon 'tudinally of said track, mounted independe ntly of said carriage and normal to the bed thereof; and means for adjustably moving said guide laterally relative to said track and carriage.

Signed by me this 19th day of June, 1930.
