PAPER DELIVERY MECHANI SM Filed Sept. 15, 1950 1 76M? MW Patented May 10, 1932 UNITED stars aren't orrics FRED ."B. COLE, OF NORWALK, OHIO, ASSIGNOB T ROTARY PRINTING COMPANY, OF

NORWALK, 01-110, A CORPORATION OF OHIO PAPER DELIVERY MECHANISM Application filed September 15, 1930. Serial No. 481,871.

This invention relates to mechanism, for use in conjunction with any machine delivering a continuous web of paper, and is adapted to lay such paper back and forth in a fan 5 fold in a suitable receptacle, for transportation, storage or subsequent use. In large printing plants, it frequently results that printing presses or other machines deliver a continuous web of paper at a time or location where it is not feasible to utilize the same in some machine which is to act subsequently thereon, as for instance a machine which may cause registering printing or may fold the previous product. Accordingly, it is necessary to transport or temporarily store the product of the first machine.

My mechanism accomplishes the desired result very eficiently, by providing a simple device which takes the web of paper as it is delivered from the first machine and folds it back and forth in a suitable container which may be used for purposes of storage or transportation. The invention is illustrated in the drawings hereof and is hereinafter more fully described and its essential novel features summarized in the claims.

In the drawings, Fig. 1 is a sectional side elevation of one embodiment of my invention; Fig. 2 is a vertical sectional view thereof in a plane at right angles to Fig. 1, looking from the right hand edge of Fig. 1.

As shown in the drawings, A. indicates a suitable web of paper which is continuously delivered by any suitable machine which has acted thereon, such machine being indicated conventionally by the pair of coacting delivery rolls 10 and 11. My mechanism takes this web and folds it back and forth into the position indicated at A1 in a suitable crate or other container 20 which may serve to store it or transport it.

As shown in the drawings, I have provided a continuously rotating drum over which the web of paper extends. This drum is shown as suspended in

brackets

31 and 32 depending from the ceiling of the room. The drum is rotated in timed relation with the machine delivering the web. To this end I have shown a belt 35 passing over a pulley 12 on the original machine and thence over a is a rock arm 58.

pulley 37 on the shaft 38 of the drum 30.

The

pulleys

12 and 37 bear the same relation toeach other as do the peripheries of the rolls 11 and 30, which makes the peripheral speed of the drum 3O equivalent to the speed of delivery of the web A to the drum.

40 and 41 designate a'pair of standards suitably supported and extending to a region adjacent the drum 30. In this region the standards carry a pair of aligned

studs

42 and 43 projecting toward each other, on which is journalled, between the standards, a swinging hollow guide 50 which has side plates converging from a comparatively wide mouth at the pivoted end to. a narrow discharge slot at the swinging end.

As shown, the two side plates, designated 51 and 52, are cut away to formlight gratings, and these plates at their ends join

end members

53 and 54 which extend upwardly in position to be journalled on the

studs

42 and 43. The end member 54 is journalled directly on the stud 43 carried by the standard 41, while the end member 53 carries rigidly with it a short sleeve 55 journalled on the stud 42. Rigidly mounted on the sleeve By means of this arm, the guiding device may be rocked back and forth as indicated by the broken lines 50 and thecurved arrow X in Fig.1.

To rock the hollow guide in'c'onformity' with the peripheral speed of the drum 30, I provide a pulley 60 on a short shaft 61 carried by the standard 31, this pulley being connected by a belt 62 with a pulley 63 on the shaft 38 of the drum. On the shaft 51 of the pulley 60 is a crank 65 which is connected by a pitman 66 with the rock arm 58. The distance between the effective crank arm 65, from the axis of the pulley 60 to the point of attachment of the pitman, is less than the effective arm 58 from the axis of oscillation of the hollow guide to the point of attachment ofthe pitman. Accordingly, as the crank 65 revolves, the arm 58 is oscillated back and forth, giving the hollow guide the swinging movement indicated by the broken lines in Fig. 1.

To vary the length of the stroke of the folded strip of the desired length, I provide several openings in the crank 65 and the arm 58, enabling the pivotal attachment of the pitman at any one of several points on either the crank or the arm.

It is important that the rate of swinging of the hollow guide be adjusted with reference to the speed of the delivery of the web of paper A, so that the product may be taken care of as fast as fed, and to that end I make the

pulleys

60 and 63 adjustable in effective periphery, so that the speed of revolution of the crank 65 may be variedavith reference to the rotation of the drum 30. As shown, cause this variable periphery by making each pulley 60 and 63in the'form of apair of cones, as illustrated in Fig. 2, one of the cones of each pulley being adjustable toward or from its mate. This movement of a cone may be made, for instance, by the nut 69 screwing onto the rotatable shaft 61 or a similar nut 39 onthe shaft 38. The belt 62 is of such form that it may occupy a different radial position in the pulley according to the adj ustment of it, as illustrated by the relative positions of this belt in the

pulleys

60 and 63 in Fig. 2. Accordingly, by loosening the cones of one of the pulleys and tightening the other, the ratio of these pulleysmay be changed, and thus the pulley 60 may be caused to rotate materially faster or materially slower than the pulley 63, as desired.

By means of the adjustments described, I am able to cause the hollow guide to swing back and forth for the desired distance in proper timed relation to the peripheral speed of the drum 30, so that the guide will lay the web of paper back and forth in thereceptacle 20, in folds of the desired length as fast as received.

My device is very simple in construction and readily installed for use with existing machinery delivering a web of paper and is adapted to receive such paper as fast as delivered and fold in a continuous back and forth fold of any desired length. When thus folded in the receptacle 20, the material is in very convenient form to be transported to some other machine, or stored temporarily until its use is required, and then it may be fed directly from the receptacle 20 to the subsequently acting machine.

I claim:

1. The combination of a rotary drum over which a web of paper may pass, means for rotating it, a hollow guide pivotally mounted adjacent the drum having a comparatively wide entrance mouth and a discharge mouth, standards pivotally supporting the guide, a rock arm on the guide, a pulley rotatably connected with the drum, a crank driven by the pulley, and a pitman connecting the crank and rock arm.

2. The combination of a rotary drum over which a web of paper may pass, an oscillatory guide for the paper pivotally supported adjacent the drum, a rock arm for oscillating the guide, a pulley adj ustably connected with the drum to rotate at variable speeds with reference thereto, a crank on the pulley, a pitman connecting the crank with the rock arm andmeans for adjusting the points of connection of the pitman with the crank or rock arm, or both.

3. The combination of a rotary drum over which a Web of paper may pass, a pivotally mounted guide adapted to receive the paper from the drum, a receptacle adjacent the mouth of the guide, means for rocking the guide back and forth, including a pulley on the drum and a pulley connected therewith by a beit, said pulleys being adjustable todifferent effective relative diameters.

In testimony whereof, I hereunto affix my signature. 7 V
