Specification of Letters Patent.

Patented Au 12,1913.

Application filed October 18, 1909. Serial No. 523,120.

To all whom it may concern Be it known that I, ERNEs'r O. CART- WRIGHT, a citizen of the United States, residing at Springfield, in the county of Clark and State of Ohio, have invented certain new and useful Improvements in Apparatus for Printing, of which the fol lowing is a specification, reference being had therein to the accompanying drawings.

This invention relates to an apparatus for printing.

The object of the invention is to so pass a sheet or web of paper between the platen and form-bed of a printing press as to enable the same to receive two or more impressions, each from a different form, either on the same or on opposite sides of the sheet or web.

A further object of the invention is to provide means for reversing the direction of movement of the paper after it has passed once between the formbed and the platen and for laterally displacing the same and thereby causing it to pass a second time between the form-bed and platen; and further, to provide means for regulating the relative positions of the impressions made by the two forms.

With these objects in view my invention consists in certain novel features and in certain combinations and arrangements of parts hereinafter to be described, and then more particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a vertical, sectional view, taken longitudinally of the forward portion of a press embodying my invention; Fig. 2 is a bottom, plan view of the turning devices; Fig. 3 is an elevation of one end of said turning devices; Fig. 4 is an elevation of the other end of said turning devices; Fig. 5 is a sectional view, taken on the line 00 as of Fig. 2; Fig. 6 is a sectional, detail view of the adjusting mechanism; Fig. 7 is a diagrammatic view showing the paper threaded through the turning devices in such a manner as to present the opposite sides of the same to the form-bed; Fig. 8 is a similar view showing the paper threaded through the turning devices to twice present the same side of the paper to the form-bed; and

Fig. 9 is a detail view of the form-bed and platen showing the arrangement of the forms and platen.

In these drawings I have illustrated one embodiment of my invention and have shown the same as applied to a platen printing press of the type shown and described in Patent No. 926,851, granted to me July 6, 1909, but, inasmuch as this press forms no part of the present invention, I have shown and described only so much of the same as is necessary to an understanding of the present invention and it will be understood that the invention is capable of application to printing presses of other types. As here shown, the printing press comprises a main frame 1, within which is mounted a fixed platen 2 and a reciprocating form-bed 3 adapted to move in a line at right angles to the face of the platen. Mounted on the upper portion of the main frame and near the forward end thereof is a suitable feeding mechanism 41 adapted to feed the paper between the platen and the form-bed from a roll, which is also supported near the forward end of the frame. This feeding mechanism is so arranged that the paper is threaded from the roll through the machine and is engaged by the feeding mechanism after it has received the printing impression or impressions.

In carrying out the invention the web of paper is fed from the roll upwardly to a point near the top of the main frame of the press, about guides (5 and 7 and downwardly over the face of the platen near one edge thereof and in a position to receive an impression from one of the forms 8, of which there are two mounted side by side on the form-bed. While these forms are here shown as distinct and entirely separate one from the other, it will be understood that the matter to be printed by the two impressions may both be embodied in the same form and may be so arranged that the two portions thereof will occupy different parts of the form-bed. After passing between the platen and formbed and receiving the first impression, the paper is passed downwardly to a point beneath the platen and there passed through suitable turning devices, comprising angle bars, as hereinafter described, which serve both to reverse the direction of movement of the web of paper and also to laterally displace the same. The paper then extends upwardly from the turning devices and passes a second time between the platen and formbed near the opposite edge of the platen and in a position to receive an impression from the second form carried by the form-bed. Thence it passes about the guide 6 to the feeding and shearing mechanism.

The turning devices are here shown as mounted in a frame comprising side members 9 and 10 rigidly secured to the lower edges of the side members of the main frame of'the press at points beneath and slightly in front of the platen. Mounted on the side members 9 and 10 of the frame are two

angle bars

11 and 12 arranged at an angle of 15 degrees to the face of the platen and extending in different directions so that their planes intersect one another at an angle of degrees. These angle bars are rigidly secured one to the other at their forward ends, where their planes intersect, and may, if desired, be formed from a single bar. The rear end of each bar is turned at an angle to the bar itself, and is mounted on the frame, as hereinafter described. In the present instance the out-turned ends of the angle bars comprise the end portions of a bar 13 which connects the diverging ends of the

angle bars

11 and 12 and extends beyond each of said angle bars, the several bars being rigidly connected one to the other and preferably formed integral. A second angle bar 14 is also supported from the frame members 9 and 10 and extends at an angle of 15 degrees to the face of the platen. This bar is arranged at a lower level than the

bars

11 and 12 and has its greatest length lying at one side of the center of the press so that it crosses the angle bar 12 near the center thereof and at right angles thereto, and, consequently, it extends parallel with the angle bar 11. The angle bar 1st has its ends 15 and 16 turned outwardly, as shown, and supported from the side members 9 and 10 of the supporting frame, as will be hereinafter described. The end portion 15 of the angle bar 1 1 preferably forms a part of a straight bar extending between the two frame members and having the angle bar 1% rigidly secured thereto and preferably formed integral therewith.

Arranged below the face of the platen and in the rear of the supporting frame for the turning devices are two

guide rollers

17 and 18, the roller 18 being in a different plane and slightly in the rear of the roller 17. \Vhen it is desired that the impression by both forms should be made upon the same side of the paper, the web is carried downwardly across the platen, under the guide roller 17, under and about the angle bar 11, thence over and beneath the angle bar 12, thence again beneath the guide roller 17 and upwardly across the face of the platen on the side opposite the side over which it passed on its downward course. The roller 17 is here shown as comprising two sleeves loosely mounted on the bar 13, between the ends of the angle bars 11 and 1.2, and free to rotate in opposite directions to accommodate themselves to the direction of movement of the paper. The roller 18 is here shown as a sleeve loosely mounted on a shaft 28 to be hereinafter described. It will be noted that the arrangement of the guide rollers and angle bars is such that the same side of the paper engages each of the bars and rollers and that the printed surface of the paper, which is the surface opposite that shown in engagement with the rollers and bars, does not at any time come in contact with these bars or rollers. The angle bars 11 and 12 each being arranged at an angle of 45 degrees to the face of the platen serve to reverse the direction of movement of the web of paper and to laterally displace the same so that it travels up in a path exactly parallel with its downward path. When it is desired to print from the two forms on opposite sides of the paper, the web of paper is fed downwardly across the platen in a position to receive the impression of one of the forms on one side thereof, thence about the guide roller 17, beneath and about the angle bar 11, thence laterally about a guide roller 19, which is arranged at right angles to the face of the platen and preferably in a position at one side of the supporting frame for the angle bars. The web of paper passes over and about the guide roller 19, thence under and about the angle bar 1 1, which, as above stated, is located beneath the angle bar 12, thence rearwardly and about the upper guide roller 18, thence over the face of the platen with that surface of the paper which has already been printed next to the platen, thereby exposing the other side of the paper to the impression of the second form. It will be noted that the arrangement of the angle bars and rollers is such that the printed surface of the paper comes in contact only with the last guide roller 18, and this roller being freely rotatable, will not smear or injuriously affect the ink on said. printed sur face.

In order that the impressions received from the two forms may occupy their proper relative positions upon the sheet or web of paper, it is necessary that means he provided for varying the distance, 0., the amount of paper, between the two impressions. To accomplish this the angle bars are movably mounted and may be raised and lowered in such a manner as to regulate the length of paper between the two impressions on the web. In the present instance this movement is secured by mounting the ends 13 of the angle bars 11 and 12 in bearing blocks 20 which are journaled in bearings 21 carried by tubular brackets 0r sleeves 22, which, in turn, are slidably mounted on vertically arranged posts 23 rigidly secured at their upper ends in sockets 24 mounted near the rear of the supporting frame. The post 23 has teeth 25 formed in one edge thereof and meshing with a pinion 26 mounted in a housing 27 carried by the tubular bracket or sleeve 22. The two pinions 26, arranged to engage the posts 23 at the opposite ends of the supporting frame, are connected one to the other by a rod or shaft 28 which is rigidly secured to the pinions and which causes the same to move in unison, thus causing the two sleeves 22 to be adjusted simultaneously and to a like extent. The shaft 28 extends beyond one of the housings 27 and is provided with suitable means for ro-' tating the same, such as a cross bar 29. A jam nut 30, of the construction hereinafter described, is rotatably mounted on the shaft 28 and adapted to be tightened against the adjacent pinion 26 to lock the pinion and the shaft against movement, thus retaining the angle bars in their adjusted positions.

The end portions 13 of the angle bars 11 and 12 extend beyond the bearings 21 and through the apertured ends of arms or links 31, within which they are secured by set screws 32. These arms or links extend forwardly and are rigidly secured to the ad jacent ends of a shaft or rod 33 by means of set screws 34. This rod is mounted in bearings 35 carried by the lower ends of links 36, which links are pivotally connected at their upper ends to the side members 9 and 10, respectively, of the supporting frame. Thus, the rear ends of the angle bars, which are mounted on the sleeves 22, are free to move in a vertical plane, the forward ends of the bars adjusting themselves to this movement by means of the links 36. The angle bar 14 has its rear end portion 15 mounted in the same bearing block 20 as the end of the angle bar 11, thus maintaining these two bars in fixed positions relatively one to the other. The outer end portion 16 of the angle bar 14 is slidably mounted in the lower portion of a bracket 37 and is secured in position there in by a set screw 38. This bracket is supported by that end of the rod 33 which extends beyond the arm 31 and has a housing 38 in which is mounted a pinion 39 which meshes with the teeth 40 formed in the upper edge of the projecting portion of the shaft 33. A similar bracket 41 is supported upon the end portion 13 of the angle bar 12 which extends beyond the arm 31 and has teeth 42 in its upper edge. The bracket 41 also has a housing 43 in which is mounted a pinion 44 meshing with the teeth 42 of the bar 12. The two pinions are rigidly connected one to the other by a rod or shaft 45 which has means, such as the cross bar 46, for rotating the same, and by means of which the two pinions are caused to rotate in unison, thus moving the brackets 37 and 41 equal distances along the

bars

13 and 33. A shaft 46 is journaled at its opposite ends in brackets 37 and 41, respectively, and has mounted thereon the guide roller 19, the position of which relatively to the angle bars is varied when the pinions 39 and 44 are actuated to shift the brackets 37 and 41 on their supporting members. The construction and arrangement of the shaft 45 and the pinions 39 and 44 and the locking means therefor is similar to that of the shaft 28 and the pinions 26. This locking means, as here shown, comprises a nut 47 rotatably mounted on the shaft 45 and screw-threaded to engage a screw-threaded opening 48 in the adjacent end of the housing 43, thus permitting the inner end of the nut to engage the pinion 44 and lock the same and the shaft 45, with which it is engaged, against rotation. Any suitable means may be provided for actuating the jam nut 47, but, in the present instance, a finger 49 is secured thereto and affords a ready means for actuating the same. By actuating the pinions and moving the guide roller 19 toward or away from the angle bars, the paper may be adjusted to cause the second impression, which, when the roller 19 is in use, is on the opposite side of the paper from the first impression, to occupy a proper position thereon relatively to the first impression.

The operation of the apparatus will be readily understood from the foregoing description. It will be apparent that I have devised a method of printing, by means of which the web of paper may be fed through the press and across the platen in such a manner as to enable two forms, both of which are mounted on the same form-bed, each to engage the paper, the impressions on the two forms being made upon different parts of the paper and in a predetermined relation one to the other. Further, it will be apparent that I have provided a simple, easily controlled mechanism for reversing the direction of movement of and laterally displacing the paper to enable the method to be carried out, and that this mechanism is adjustable to permit the relative positions of the two impressions to be regulated, whether these impressions be on one side of the paper only or on opposite s1des the reof. In thls manner I am enabled to prlnt in two colors upon the same side of the sheet of paper or to print on both sides of the sheet of paper, both sides being printed in the same color or each side in a different color, the paper being passed through the press but once to receive both impressions.

\Vhile I have shown and described the mechanism in connection with a continuous web of paper it will be obvious that the invention is not necessarily confined to the use of such a web of paper. Therefore, I wish it to be understood that I do not desire to be limited to the details of construction shown and described, for obvious modificat-ions will occur to a person skilled in the art.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is
