JOGGER FOR PAPEE-FOLD TNG IvIACI-IIN Application filed me 22, 1912. Serial lea-705,322;

To all whom it may cjoncern I Be it known that I, CLARK A. S1eAroos,'a citizen of the United States and a: resident of Omaha, in the county of Douglas and Statejof Nebraska, have invented certain new and useful Improvements in Joggers for laper-Folding Machines, of which the following is a specification.

My invention relates to paper folding machines and more particularly to the devices known as Joggers or paper straighteners It is the object of my invention to provide a paper straightening and gaging device of simple and inexpensive construction, which may be quickly and easilyadjusted to different positions so as to accommodate sheets of varying sizes, and having a special form of driving connection by which the straigh the straightening and gaging devices .are

connected and with which they directly cooperate. The said parts are the framemembers 1 and 2, the-carrier-belts or'tape's 7' 3. a driving roller 4: and a driving shaft 5.

The general arrangement and functions of 3 these parts will be apparent.

or carrier-belts 3 are those on which the pa- The tapes per is received when first delivered to the folding machine, and they move continuously in the directions indicated, at one end passing around a roller 6 vand at the other end passing around small individual pulleys 7 as indicated in Fig. 3. On the framemembers 1 and 2, respectively, are secured standards Sand 9, and upon the latter standard is revolubly' mounted a small pulley 10.

A. transverse endless belt 11 passes around the driving rollerl, thence the upper and lower portions of said'belt are reversed by crossing them, and they then pass" around the pulleylO, across the machine between" the upper and lower portions of the carrierbelts, and around a pulley 12 disposed in horizontal alinement with the pulley 10, so that the upper portion of the transverse belt lies just beneath and in contact with the upper-portions of the carrier-belts. The

pulley 12 is journaled on a lever 13 which 1S pivotally connected with the standard .8. i v

Through. the upper end of the. lever 18 is passed a small adjusting screw'ltof which theend may be screwed in against'the standg ard so as to push the lever outwardlyjand tlghten the transverse belt.

Specification of LettersPatent. Patented De 15 1914 I In the upper partsof the standards 8 and 9 arecarried theparallel transverse rods 15 and 16, the same beingdisposed slightly below the'upper portion of the transverse belt 11, the rod 15 being behind the said belt and the rod 16 being in front of the belt when viewedas in Fig. 1. The endsot the rod 15 areffixedly secured in the standards,"

and thero'd 16 is revolubletherein, the portionof said rod between the standards being threade'd'u Theouter end portion of the rod 16 has a pin 17 passing through it, said pin being adapted for engagementwith a notch formed in the tubular hubportion of a crank 18 which is removably disposed on the end of the rod for the purpose of enabling itto be readily turned. The innerend portionof the rod 16 is reduced in size and, after passing through the standard '9, has a 'coil spring 19placed around it, the one endofthe spring bearing against the'face of the standard and the other end pressing against a washer held on the end of the rod by a pin 2-0. On the central portions of the 90."

rods 15 and16 is supported the plate 21 the f same being slidable on the rod 15, and being movable transversely along the rods by turningthethreaded rod 16 which is screwed through it. Along the outer edge of'the plate an upwardlv extending guide-flange 22 of Whichthe ends are curved outwardly,

as shown in Fig. 1. The upper surface of the plate .is so disposed as to be in contact 'with' the carrier-belts which pass over it,

and in said upper side of the plate is a transverse groove 'throu e'h which the belt 11 asses, as shown in Figs. 2 and 3. "A'notch is formed in the guide-flange 22 etrinciden't with the groove in the plate, and at the sides of said notch are outwardly extending lugs 23 between which is pivotally mounted the roller-arm 24. Said arm extends inwardly from the pivot-pin, its inner end is turned upwardly and forked, and between the forked ends is revolubly mounted the ing member 27 ,which passes inwardly from c the arm and around a small pulley carried on the end of a lever 28, thence outwardly and around a pulley 29 mounted on the standard 8, and thence extends inwardly and has'its other end connected with the outer edge of the plate 21. The lever 28 is fulcrumed on a lug extending out from the side of the frame-member 2 and its lower end lies adjacent to a cam 30 carried on the driving shaft'5. On said end of the lever is-a roller 31 which is held in engagement with the cam by means of a spring 32, connected with the lever and the frame, as shown. When the flexible connecting member 27 is not placed in tension by movement of the lever 28 the weight of the roller 25 causes it to drop into engagement with the transverse belt 11, or, if a sheet ofpaper is being conveyed over the plate 21 by the carrier-belts, to press said paper down into engagement with the transverse belt. When the flexible connection is placed in tension by movement of the lever 28 the roller-arm is swung upwardly, and paper carried by the belts 3 can pass freely under it.

In the operation of the mechanism the belts 3 and the transverse belt 11 are each moved continuously in the directions indicated in the drawings. The plate 21 is adjusted transversely by turning the threaded rod 16, so that the inner side of the guide-flange 22 is at the position to which it is desired to gage the edges of the sheets of paper being conveyed by the belts 3; The lever 28iis actuated intermittently by the cam 30 so that the flexible connection 27 is alternately placed in tension and the tension relaxed.

When the tension on the member 27 is relaxed and the roller 25 thereby permitted to drop down, the paper is pressed against the belt 11 and moved transversely thereby until its outer edge is brought into engagement with the guide-flange 22. The parts are so proportioned that after the edge of the paper is brought to engagement with the guide-flange the tendency of the belt 11 to move it farther will be insuflicient to cause the paper to wrinkle or bulge upwardly. Should the paper tend to'bulge upward between the roller and guide-flange, it is held down by the portion of the roller-arm adjoining the forked end thereof.

' It should be especially noted with reference to the flexible connection for actuating the roller-arm, that by the peculiar arrangement of the cord 27, when the position of the plate 21 is changed the driving connection is also changed automatically and the timing of the movement of the roller-arm is not changed. Thus, if the plate be moved either inwardly or outwardly, the ends of the cord attached to the plate and to the arm 26 are both moved in the same direction and the cord passes around the pulleys on the lever 28 and standard 8 to permit the movement. By this meansthe operator is enabled to change the position of the gage and straightener even while the machine is running, the crank 18 being turned with one hand while the other hand is used to lift the upperportions of .the belts 3 over the roller 25, roller-arm, guide-flange and the lugs 23, when the transverse movement given to the plate is suchthat the said parts must move past any of the carrier-belts.

Now, having described my invention, what I claim and desire to secure by Letters Patent is:

1. In a device of the class described, the combination with carrier-belts, of a stationary frame, a gage, means for adjusting the position of the gage transversely of the carrier-belts, conveying means for moving paper transversely of the carrier-belts toward the gage, a pressing device carried on the gage and adapted to engage paper on the carrier-belts to hold the same against said conveying means, an intermittentlymoving actuating-lever for, said pressing device, and a unitary flexible element slidably engaging the frame and connecting the actuating-lever and pressing device so as to transmit the movements of the former to parts slidably connected with the actuating lever and the frame, for the purpose set forth.

3; In a paper folding machine, paper carrying devices, a frame, a jogger mechanism for moving paper transversely to the carrying devices, means for varying the position of the. jogger mechanism transversely to the 1,120,983 ,2 i i i 3 carrying devices, an actuating lever for the In testimony whereof I have hereunto jogger mechanism, and a flexible member subscribed my name in the presence of tw having OIIIIG of its'ends clcnnected vvithha fixeg Witnesses.
