To all whom it may concern.-

Be it known that I, HENRY HAETT, a citizen of the United States of America, and a resi-' dent of Chicago, county of Cook, State of Illi nois, have invented certain new and useful Improvements in Delivery Apparatus for Printing-Presses, of which the following is a specification.

My invention relates to delivery apparatus for web-perfecting presses, and has for its object improvement in certain details of construction hereinafter specified.

In the accompanying drawings, Figure 1 is an end elevation; Fig. 2 is a side elevation. Fig. 3 is a detail similar to Fig. 2, showing a different position; and Fig. 4 is a perspective view showing the course which the webs follow in bringing three webs upon the former.

In the said drawings, is a V-shaped former pivoted on the shaft 11 and supported from the frame 12 by the adjustable brace 13. Along the sides of the V of the former are secured a series of hemispherical projections or corrugations 14, the object of which is to reduce the tendency to wrinkle and pinch when two or more superimposed webs pass over the former 10. Supported on the shaft 15 are two arms 16, which carry a guide-roller 17 The roller 17 is journaled in boxes 18, which are adjustable in the arms 16 by means of the screws 19. An adjustable stud 20 serves as a means for limiting and adjusting the vibratory movement of said arms 16, and consequently the roller 17, in one direction. A spring 21 on the stud 20 serves to resist movement in the opposite direction, and a nut 22 serves as a means for regulating the amount of such resistance. At one side of and somewhat above the roller 17 and the apex of the former 10 are the pulling- rollers 23 and 24, one of which is adjustable by means of screws 25 and blocks 26. On the shaft 11 is a roller 27, the periphery of which is in line with the face of the former 10. Located at the rear of and slightly below the roller 27 is an idle roller 28, under which the webs pass and from which they pass over the roller 27 to the former 10. In front and above the roller 27 is a roller 29, which is driven from roller 27 by the gears 30. J ournaled in the top of the brackets 31 on frame 12 is an idle roller 32, and just be= low this is another roller 33, which is journaled in boxes 34, that are vertically adjust able by means of screws 35. Mounted on the rollers 29, 32, and 33 are the tapes or belts 36, which come in contact with the upper web as it passes over roller 27 to the former 10. The speed given to these belts is such as will maintain the upper web at the same speed as the other webs, and the amount of grip or bite which the belts have on the web is determined by the vertical adjustment of the roller 33. For example, when the roller33 is at its upper position, as shown in Fig. 2, there is but a slight contact between the roller 27 and the belts 36; but when the roller is at its lower position, as in Fig. 3, the arc of contact is very much increased. It will be apparent that the screws serve as a means for obtaining any degree of contact between these extremes. To compensate for the differences of belt length due to different positions of the roller 33, there are a series of belt-tighteners consisting of rollers 37, carried on the arms 38, which arms in turn are secured to shaft 39 by set-screws 40. The shaft 39 is supported in brackets 41 and is or may be held from turning by means of the set-screws 42.

From the foregoing description it will be evident that the bite of the belts 36 or their controlling action by virtue of their contact with the face of the upper web passing over the roller 27 is adjustable by means of both the arc of contact and the tightness of the belts 36. With the roller 33 at a fixed point the amount of controlling action can be varied by varying the belt tension through adjusting the tightening rollers 37. With the rollers 37 in a fixed position the belttension .and the arc of contact may be adjusted to- 10 the folded webs pass under the guide-roller 17 to the pulling- rollers 23 and 24 and from thence to the ordinary cutting and folding cylinder. The adjustment of the roller 17 laterally by the screws 19 and vertically by means of the stud 2O permits its location at such point as will be most advantageous for the number of webs and quality of paper handled. The spring 21 permits the roller17 to have a slightly-vibratory action whenever there may be variations in the tension of the webs between the former 10 and the pullingrollers 23 and 24.

What I claim is 1. In the delivery apparatus of a printingpress, a V-shaped former provided with hemispherical projections gations on the gflollers, of an idle roller, pivoted arms edges of the V, substantially as described' 2. In the delivery apparatus of a printingpress, a former provided with corrugated edges, adjustable tension devices for paper passing to said former, and other adjustable tension devices for paper passing from said former.

3. In the delivery apparatus of a printingpress, a roller over which superimposed webs pass, a belt or tape in contact with the upper web as it passes over said roller, and means for varying the are through which such contact occurs.

4. In the delivery apparatus of a printingpress, a roller over which superimposed webs pass, a belt in contact with the upper web as it passes over said roller, and means for varying both the force and the arc of contact of said belt.

5. A former, a pair of pulling-rollers laterally removed from the apex of said former, an idle roller serving as a guide-roller and located between said pulling-rollers and said former, and means for adjusting the position of said idle roller.

6. The combination with a former and pullin g-rollers laterally removed therefrom, of an idle roller serving as a guide-roller and located between said pulling-rollers and the apex of said former, and devices for adjusting said idle roller both vertically and laterallv.

7. The combination with a former and pullin g-rollers laterally removed therefrom, of an idle roller serving as a guide-roller, pivoted arms upon which said idle roller is supported adjacent to the apex of said former, and devicesfor adjusting the position ofsaid idle roller in said arms.

8. The combination with aformer and pullupon which said idle roller is supported, devices for adjusting the position of said idle roller on said arms, and other devices for adjusting the position of said arms on their pivot.

9. The combination with a former and pulling-rollers laterally removed therefrom, of a guide-roller located between the two, and means for permitting said guide-roller to vibrate under the tension of webs passing from said former to said pnllingrollers.

10. In combination with aformer, a guideroller located adjacent to the apex of said. former, means for permitting said roller to vibrate under the tension of webs passing from said former, a spring for resisting such vibration, and means for adjusting the tension of said spring.
