Specification of Letters Patent.

Patented Feb. .1 6, 1 91 5.

Application filed July 3, 1909. Serial No. 505.925.

To all whom it may r-oncern Be it known that I, CLARK A. Srearoos, a citizen of the United States, residing at Omaha, in the county of Douglas and State of Nebraska, have invented certain new and useful Improvements in Paper-Folding Machines, of which the following is a specification.

My invention relates to machines for fold-- number of guides formaintaining it in such alinement. In the'usual construction of machines of thls class, 1n which a series of tapes are passed over the same rollers,

the maintenance of a uniform tension thereon'is difiicult by reason of the unequal expansion and contraction thereof due to changes ofatmospheric moisture and temperature, and the unequal stretching of old and new tapes. It is also desirable that the transverse intervals betweenl thetapes of each series may be adjustable in order that .the tapes may. be. placed .in the positions for handling any particular.

best ada ted width 0 paper. It is also desirable that the gages for limiting the movement of the paper by any series of tapes be positioned adjacent to the tapes, and when the transverse positions of the tapes are ad usted that similar transverse adjustments of the gages be made simultaneously therewith.

My invention provides a simple, efficient and inexpensive device for attaining all 0 the above desirable effects.

Constructions embodying my invention are illustrated in the accompanying drawings, in which Figure 1 is a side elevation of the device,

Fig. 2 is a plan view thereof, and Fig. 3 is a front elevation of the same.

In carrying out my invention I provide brackets 1 each over ahorizontal member 2 of the machine frame, the lower portion of the bracket fitagainst the face of the frame memberfiange 3 extending over the top tin an a ported thereon,

' 1 at the side thereof the innerside of the bracket shoulders 14 of a form adapted to fit so arranged thereof, as shown. In the lower partof the bracket is a horizontally extending slot through which is passed a bolt 1- extending also through the frame member By means of said bolt the bracket is secured to the frame member so as to be adjustable longitudinally thereof, the flange 3 preserving the alinement of the parts. Through the upper part of the bracket at one side thereof acylindrical rod 5 passes slidably and rotatably'through the bracket, the rod having at its inner end a fork 6 in which is journaled a tape pulley 7. 'The outer end of the rod is threaded and provided with a nut 8, and around the rod between said nut and the bracket. is'disposed a coil spring 9' of which the tension may be adjusted by varying the position of the nut upon the rod. By means of said spring the tension upon the tape 10 which passes over the pulley 7 is maintained substantially the same even though the length of the tape may be varied slightly by stretching or by changes of atmospheric moisture or temperature, and if at any time the tape tension is not as desired it may be quickly adjusted by turning the nut upon the threaded rod 5 to change'the' tension of the spring 9.

As my devioe-is to be applied to each of have shown butfrom a single roll in.

two parallel portions connected by a U- shaped bend 13. The parallel portions of the rod are passed through openings in the gage plate 11 which is thus slidably supand the ends of the rod are passed through openings in the bracket opposite the rod 5. At

are made in the rod and the outer ends thereof 15 are bent down over the face of the bracket, as indicated, so that the rod is thereby retained in position in the bracket. The parallel guide portions of the rod are as to be slightly above the upper side of the tape 10 and the inner ends said portions are slightly upturned at the bend 13, so that the rod forms a guide to prevent upward buckling of the paper which is carried by the tape into engagement with the gage plate 11. The gage 'plate .is adjustable longitudinally ofthe guide rod by means of the screw 16 which is threaded through the bracket 1, connected at the inner end to the gage plate, and carries at the outer end a small hand wheel 17 by which the screw may be turned. Since the bracket 1 carriesfiboth the tape pulley and gage plate, transverse adjustment of both, without changing the relative positionsthereof, may be made by loosening the bolt 4, moving the bracket to the desired position, and then tightening the bolt.

It will be apparent that 'by the use-of the device described, all the tapes of a foldingmachine may be adjustedto and auto-- inatically preserved at a substantially uniform tension, the gages for limiting the 3o gage.
