sPnoIFIcArIoN forming part'of Letters Patent No. 740,592, dated Qatar 6, 1903. Application filed October 173, 1902. Serial No. 127,198. (No model.)-

To all whom it may concern:

Be it known that I, GEORGE W. SoHooK, a

citizen of the United States, residing at South My invention has relation to improvements in paper-folding machines; and the object is' to provide a simple and effective means for deflecting the folded sheet as it passes from between the folding-rollers in either direction.

The invention embodies a double-inclined deflecting device arranged under the foldingrollers and mechanism for shifting the dc fieotor so as to deflect the sheet either toward the front or rear of the machine.

I have fully and clearly illustrated my improvements in the accompanying drawings, to be taken as a part of this specification, and wherein Figure 1 is a top plan view of a pair of folding-rollers, shown as broken away at the middle portion to disclose the paper-defiect-' ing plate or device.

Fig. 2 is a side view of the feed-end portion of a paperfolding machine, showing the lever and slotted armfor holding it in set position. Fig. 3 is a view showing a portion of the frame, the folding rollers in cross-section, and section throughthe deflecting-plate with the shifting mechanism. Fig. 4 is a detail side View of a portion of the deflector-plate and the shifting mechanism connected therewith.

Referring to the drawings, wherein the a same designations are used to point out simi lar parts or elements in the several figures, 1 2 designate the side rails of the frame of the machine, wherein are journaled a pair of folding-rollers 3 t in the usual manner, and

across the machine, preferably in advance of the rollers, is mounted a rock-shaft 5, one

end of which, as 6, projects through the side rail or plate of the frame and has secured thereto a lever 7, whereby the shaft may be rocked in its bearings. The lever 7 is provided with a clamping-screw S, the neck of .which is posited in a curved slot 9 in arm 10, secured to the face of the frame-rail. It will be seen that when the lever is moved to a desired position it can be 'set by tightening up the clamping-screw. Adjacent to each end of the rock-shaft 5 is a radial arm 11, by

means of which the shifting mechanism is operated.

Supporting-rods 12 are pivotally secured at their lower ends to the inner faces of the frame and have their upper ends bent at right angles to their bodies, as at 13, to the inner ends of which are pivotally connected one end of the connecting bars or links 14:, the other ends of which are connected to the radial arms 11.

15designates the device or plate for deflecting the foldedpaper 16 in the desired direction as-it passes through the rollers. This paper-deflector consists of a body having its' working faces inclined in opposite directions, as shown, the faces of which are preferably concaved in vertical direction. The ends of the deflector are closed and are pivotally mounted on the parts 13, as clearly seen in Fig. at of the drawings.- 7 7 It will now be seen that by rocking the shaft 5 the deflector may be moved with a substantially horizontal slidable movement to the position seen in full lines in Fig. 3,

and the paper will be turned in the direction of the rear of the machine to be subjected to subsequent operations of the mechanism to produce additional folds; but ifbut a single fold is all that is desired then the deflector is shifted to the position indicated by the dotted lines in Fig. 3, and the paper will be deflected toward the front of the machine and on severanee drop as desired.

Having thus described my invention, what I claim, and desire to secure by Letters Patout, is--- 1. The combination with the folding-rollers of a folding-machine, of a slidable deflecting member located below the rollers and having its front and rear faces converged upwardly to a common dividing edge, and means for slidably shifting the deflecting member back and forth in a substantially horizontal plane to alternately direct the work in opposite directions.

2. In a paper-folding machine, the combi nation with the first pair of folding-rollers, of a triangular deflecting-plate arranged under the rollers having coneaved surfaces, a rock shaft, pivotally mounted bars to support the plate, a connection between the rockshaft and the pivotal supports, and a lever to rock the shaft.

3. In a paper-folding machine, the combination with the first pair of folding-rollers, of a deflecting-plate having double-inclined sides concaved in vertical direction, pivotallysupporting arms having their upper ends
