SHEET-REGISTERING CONVEYER.

To all whom it may concern:

Be it known that I, ARNOLD B.- ANDERSON,

' a citizen of the United States, and a resident of Nanuet, in the county of Rockland and v State of New York, have invented a new Conveyer,

and Improved Sheet-Registering 1 d cear, an

This invention relates to sheet .conveyers for box making machines, presses, folders and the like, and-has to deal more particularly with means for automatically causing the sheets to. be automatically registered or uniformly fed into the machine with which the conveyer is used.

The invention has for its general objects to improvev and simplify the construction andopera'tion of apparatus of 'the characterreferred to so as to. be reliable and .eificient in use, comparatively simple and 1nexpensive to manufacture and keep in operative condition, and so designed as to be readily convertible to permit the sheets to be regrsteredby either edge. A further object of the invention is'the provision of means cooperating; with the feed rolls of the sheet conveyerto cause a sheet to automatically move into engagement with agage and be maintained in such engagementwwhile the sheet is being conveyed by the rolls, the effect being that suc-= cessive sheets I will feed uniformly in the same position or in registration.

Still another object is the employment in connection with the conveyer rolls of endless belts which extendv parallel .with the rolls'and are driven in either direction ac-- cording to which of two gages is used as the means for registering the sheets, and by the combined action of the conveyer rolls and belts each sheet when placed on the conveyerv will have a composite movement due to such combined action, so that a' sheet as it is fed forwardly will be moved into engagement ,withthe gage andbe maintained in such engagement until the sheet passes out of the conveyer, with the result that all sheets will feed into the machine in the same manner.

With such objects in view, and others.

which will appear. as the description proceeds, the 1nvent1on comprlses various novel features of construction and arrangement of parts which will beset forth with particu' larity in the following description and claims appended hereto.

Specification of Letters Patent.

' Patented Apr. 4, 1916.

Application filed November 28, 19 14. Serial No.874,492.

.In the accompanying drawings, which bars 1 and 2 are bearings 3 for the journals 4 of rolls 5. These rolls are arranged par= allel to eachother and close together and rotate all in the same direction, so as to feed a sheet in a direction at right-angles to the axis of the roll, the sheet being placed on top of the rolls, and by the contact of a plurality of rolls at. one time on the sheet, the latter is moved forwardly. These rolls 5 may be "driven in any suitable-manner, as, for instance, by sprocket wheels 6 engaging with an endless sprocket chain 7, as shown in Fig. 4, such chain receiving power from a shaft 8 at the delivery end of the mecha; nism. At the delivery end of'the mechanism may be employed'any suitable means for feeding away the sheets, as, for instance,

two coacting feed rolls 9 and 10, which, of

course, constantly rotate in one direction, as do also the conveyer rolls 5. Extending transversely of the. rolls and at the ends sheets to engage one gage or'the other, such means comprising a plurality of endless smooth belts 15 which extend parallel with the rolls 5,. with one belt lying between each pair'of adjacent rolls, and the upper surfaces of the upper flights of these belts are approximately in the same plane with the top of the rolls 4, so that a sheet will have simultaneous engagement with such rolls and belts, whereby the sheet when first placed in themechanism will have a 'composite movement which is the-resultant fo'rwardly-conveying impulse of the rolls 5 and the laterally-conveying impulse of the belts 15, and this lateral movement will continue until the sheet comes into contact with the proper gage 11 or 12, and the engagement will be maintained between the edge of the sheet and such gage as long as the sheet is being moved forwardly by the rolls 5.- The belts 15 pass around lateral rolls or pulleys 16 and 17 and either one of these pulleys will act as a driver, according to the direction in Which the belts are to travel. These pulleys 15 and 16 are provided respectively with clutches 18 and 19, whereby either pulley can be connected with a common driving means, such as the shaft 8 of the lower feed roll 10, there being beveled gears 20 between the shaft 8 and the clutches 18 and 19. To prevent the gages from interfering with the belt the gages have recesses 21 in their bottom edges,as shown in Fig. 4, and the upper flight of a belt passes through each recess, and the portions 22 between the recesses 21 are engaged by the edge of a sheet as the latter is fed forwardly. It will be observed that the clutch 19 in Fig. 1 is closed, so that the pulley 1'2 is the driver for the belts 15, and it drives the belts in a direction indicated by the arrows placed on such belts, so that if a sheetis applied to the conveyer mechanism while the rolls 5 are rotating. and the belts are traveling, the sheet will travel forwardly and at the same time move toward the gage 12, this being due to the fact that the sheet is gripped both by the rolls. and the belts. The belts will continue to exert a draft on the sheet, whereby it will be maintained in engagement with the gage 12 while the rolls continue to cause the sheet to travel forwardly. When the other gage 11 is to be used, the clutch 19 is opened and the clutch 18 closed, whereby the belts 15 will travel in the opposite direction and cause the sheets to engage the gage 11. The clutches are provided with shifting levers 23, Fig. 2, and in order to maintain the belts taut the same are provided with tighteners 24, asshown in Fig. 3, such tighteners engaging the lower flight of the belt.

From the foregoing description taken in connection with the accompanying drawing, the advantages of the construction and method of operation will be readily understood by those skilled in the art to which the invention appertains, and while I have described the principle of operation, together with the mechanism which I now consider to be the best embodiment thereof, I desire to have it understood that the mechanism shown is merely illustrative and that such amazes changes may be made when desired as are within the scope of the appended claims.

-Having thus described my invention, I claim as new and desire to secure by Letters Patent: 7

l. A mechanism of the class described comprising means for forwardly feeding sheets of paper, continuously traveling spaced parallel belts associated with the said means and extending transversely to thedirection of travel of the sheets to impart a lateral movement to the sheets, and a gage against which the sheets are maintained by the belts during the forward feed of the sheets, said gage being in the form of a bar having recesses in its bottom edge in-which the belts run, whereby the portions of the gage between the recesses extend below the plane of the sheet-engaging portion of the belts.

2. A mechanism of the class described comprising a plurality of closely arranged parallel rolls rotating in thesame direction, means for driving the rolls, endless tapes disposed parallel and each arranged between adjacent rolls, and the top plies of the tapes being in a common plane in which the tops of the rolls lie, rolls extending transverse to the first-mentioned rolls and disposed outwardly beyond the ends thereof and around which the endless tapes pass, means for rotating the last-mentioned "rolls to move the tapes simultaneously in the same direction, and a gage extending parallel with and disposed across the tapes and first-mentioned rolls, whereby the tapes move the sheet laterally against the gage'while the first-mentioned rolls feed the sheet forwardly.

3. A mechanism of the class described comprising a plurality of parallel rolls rotating in the same direction for conveying a sheet forwardly, a plurality of gages between which a sheet is placed on the rolls, endless belts extending parallel with and etween the last-mentioned-rolls and adapted to engage a sheet simultaneously ARNOLD B. ANDERSON.
