UNITED STATES WILLIAM H. LONG, OF NEW YORK, N. Y.

PRINTING PRESS.

Application filed February 26, 1919.. Serial No. 279,284;

To all whom it may concern:

Be it known that I, WILLIAM H. LONG, a citizen of the United States, and a resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Print ing Presses, of which the following is a specification,

The invention relates to printing presses, and more especially to printing presses adapted to either print in a plurality of colors, to perfect the impression receiving material, as may be desired, or to print upon 'ones'ide of two webs, or other impression receiving material, run through the press to ther.

he objects and advantages of the invention will be set forth hereinafter in part, and in part will be obvious herefrom, or may be learned by practice with the invention; the same being attained through the instrumentalities and combinations pointed out in the appended claims.

The invention consists in the novel parts,

constructions, arrangements, combinations and improvements herein described.

The accompanying drawings, herein referred to and constituting a part hereof, illustrate one embodiment of the invention, and together with the descri tion serve to explain the principles thereo Of the drawings:'

Fig. 6 is an elevation, partly diagram matic, of the lower part of a press, showing a different form of. mechanism for chang ing the relations of the press cylinders, and

showing the off-set cylinder in printing relation with the sion cylinder;

Fig. 7 is a similar view to Fig, -6, but showing the off-set cylinder out of printing relation, and the late cylinder; cooperating plate cylinder and impresdirectly with the arge cylinder which may operate as an impression cylin or or as an F We'bs concurrentl by means of changing the positions and re at1ons of thelcylinders in Fig. 8 is an enlarged fragmentary detail accordance with the kind and manner of printing desired; and in accordance with certain features of the invention,- it is applied td what is known as ,ofi-set printing, plate printing, and to a combi: nation of direct late printing and of oifurther features and objects of the invention will 'appear hereinafterin connection with the description of the embodied machine and of the operation thereof.

Referring by way of example to the illustrated embodiment, a form cylinder 1 is provided, having inking mechanism, indiwhich mechanism in its details of construction may n acordance with certain features of the invention,' the cylinder 1 is construct- .ed and adapted either for printing directly.

'cated generally by the reference numeral 2, i

be of any acceptable or approved I upon a web,'or.-for printing upon an off-set,

inder then printing upon the web.

In carrying out this feature of the invenor rubber-surfaced cylinder, this latter vcyl- I tion, there is provided a cooperating oifset cylinder 3, and a cylinder 4. This latter cylinder in the arrangement of the press il-- lustrated in Fig. 1, operates as an' impression cylinder, but in the inter-relation of the cylinders shown in Figs. 2 and 3 it is adapted to operate as an off-set cylinderq'or asacombined off-set and impression cylinder, receiving the impressions from the cylinder 1 and imparting them to the web as will be later described.

Means are provided for changing theposi- A tions and inter-relation of the cylinders 1, 3

and 4, for the purposes and objects described, and in the embodied form thereof the cylinder 1 and its inking mechanism 2 are mounted upon a frame 5 having base plates 6 and? which are slidable on guideways 8 and 9 formed on' the press frame 10. On the base plates 6 and 7 at either side of the press, are formed gear racks 11 and 12, and meshing with these gear rack bars, respectively, are pinions 13 and 14. Pinions 13 and 14 are fixed upon a shaft 15 which is journalled at 16 and 17 in the press frame. The shaft 15 is provided with a squared head or heads 18 for the application of a crank.

In the embodied form of the invention, the cylinder 1 is adapted to use planographic metal plates stretched upon the surface of the cylinder in a well-known manner. Suitable damping mechanism, which may be of standard or other convenient form, is provided for damping the planographic printing plates preparatory to inking. By reason of the fact that in the present embodiment the direction of rotation of the cylinder 1 is'reversed, dependent upon whether it is in direct printing relation with cylinder 3 or cylinder4, in my preferred embodiment, I provide two damping mechanisms,one such mechanism cooperating with the cylinder 1 while running in one direction, and the other damping mechanism cooperating with the cylinder when it is rotating in the opposite direction, so that the damping operation .may in anyevent precede the inking operation.

mechanism 23 is provided, mounted upon the frame IQ of the press, and in position to cooperate w1th the press cylinder 1 when the cylinder 3 is interposed as aprinting ele-,

ment or instrumentality between the cylinder 1 and the cylinder 4, as shown in Fig. 1. A second damping mechanism 24 is w mounted upon the press frame, and is in po sition to cooperate with the cylinder 1 when; that cylinder is printing directly upon the it into operative relation with elther the one damping mechanism or the other. 1

By" rotating shaft 15. cylinder 1 is slid along the press frame 10, to the left-hand position as in Fig. 1 when cylinder 3 is interposed as one of theprinting cylinders, and to the rlght-hand position as inFigs.

2 and 3, when cylinder 3 is out of operative position and cylinders 1 and 4 cooperate directly.

In the embodied form thereof, a damping In the first of these two positions, cylinder 1 moves into operative relation with damp ing mechanism 23 and in the second of these positions cylinder 1' moves into operative relation with damping mechanism 24, as already described. v

In theembodied form of means for moving cylinder 3 into .and out of operative printing relation with cylinders 1 and 4, and as illustrated in Figs. 2, 4 and 5, cylinder 3 is elevated to what may be termed inoperative or non-printing position and is lowered into what may be termed the operative o1 printing ,.position. Referring in detail to the embodied means for so raising and lowering cylinder 3, the cylinder is journaled at-either end thereof in a" journal block 25. Each of the journal blocks is provided at either side with registering recesses 28 and 29 which are in position to cooperate with registering pins 30 and 31. This holds the cylinder firmly to position against the squeeze or pressure of the other cylinders.

The illustrated means for raisng and lowering the cylinder 3 comprise further lugs 32 fixed to or integral with the journal blocks 25 at either side of the cylinder. Th'ese lugs are internally threaded, and vertically disposed screw rods 33 pass therethrough at either side of thepress. The screw rods are journaled in top and bottom beari- n lugs 34 and 35 on the machine frame at eit er side. Across the press frame extends a shaft 36, having at either end thereof a pinion 37, which pinions mesh respectively with a diagonal or worm gearing 38 on-the bottom. end of each of the screw shafts 36. The shaft 36 has a square end 39, whereby it may be rotated, to turn the screw shaft 31 and thereby to raise or lower the cylinder 3 from inoperative or non-printing to operative or printing position and vice versa.

. 'Cooporating with the cylinder 4'isa cylinder '45, which is preferably an off-set cylinder and cooperating with cylinder is a plate cylinder 46, which is preferably a planographic cylinder, similar tocylinder 1.

Cylinder '46 is provided with an inking mechanism 47. and'with a damping mechanism 48 both of, which may be of standard or other suitableform. The various cylinders are driven by gearing of suitable design,'but which is'not shown in the drawing; The manner of operation of the hereinbefore described mechanism. and the arrangements of the web or other impression receiving material for the various ways of print-- ing and interrelation of cylinders, is substantially as follows:

In Fig. 1a web 50 is shown in a roll at the left hand side, and is threaded through the machine. passing between cylinders 3 and 4, and between cylinders '4 and 45, and

' out of the machine.

In the positions and inter-relations of the cylinders shown in Fig. 1, plate cylinder 1 rints upon off-set cylinder 3, which cylinder prints upon the web 50, the cylinder 4 acting merely as an impression cylinder. The plate cylinder 46 prints upon off-set cylinder. 45, which in turn prints upon the web 50, as it passes between the cylinder and the cylinder 4, the latter cylinder acting as an impression cylinder. This arrangement of the impression-receiving material and this interrelation on the cylinders provides for printing in two colors upon one side of the web.

*In Fig. 2 of the drawings, cylinder 3 has been moved to the non-printing or inoperative position, and plate cylinder 1 has been moved into contact with cylinder 4, the impression-receiving material being in the form of a web roll 51 and passing between the cylinder 4- and the cylinder 45. The plate cylinder 1 now prints upon the cylinder 4, which latter cylinder operating as an off-set cylinderprints in turn upon the web 51. Plate cylinder 46 prints upon offset cylinder 45. in the manner already described, and cylinder 45 in turn prints upon the opposite side of the web 51 from cylinder 4.- Cylinders 4 and 45 in this arrangement act as off-set printing cylinders to print ,upon one side of, and thereby to perfeet, the web, each cylinder at the same time acting as the impression cylinder for the other.

In Fig. 3 of the drawings, two webs 52 and 53 of impression receiving material are shown in roll form and as passing between the cylinders 4 and 45, which cylinders operate in the same manner as last described.

reason of the two webs bein run together through the press, each web is printed upon one side only, insteadof securing a perfected web as is the case when a single web is run through, as shown in Fig. 2.

If desired, one of the two simultaneously the web 53 will'run through in the manner shown in Fig. 3 and as already described,

' but the other web will run through in the same manner as the web 50, being printed upon by the plate cylinder 1, the cylinder 55 4 in the case acting only as an impression cylinder, while the web 53 will be printed by" the cylinder 45 in off-set as already described. Driving gears for cylinders'l, 3.

and 4 are shown in Figs. 4 and 5, but are omitted from Figs. 1, 2 and 3 for the sake of clearness. It will be understoodthat the driving connections for the press may'be of an usual and suitable character.

n Figs. 6 and .7 are shown a different form of mechanism for changing the relation. of the cylinders 1; 3 and 4. In this form or embodiment of the mechanism, the

off-set cylinder 3 is moved downwardly,

pinions 59, which pinions are fixed on a shaft 60, the, shaft being journalled in the press frame. The shaft has squared heads to take a crank, the rotation of the shaft moving the cylinder 3 into and out of printing or operative relation with the plate cylinder 1 and impression cylinder 4.' v

Means are provided in connection with the last-described mechanism for holding in position and for regulating or adjusting the position of clinder 3. As embodied, on the bottom en of the slidable frame 56, at either side thereof, are provided a stop and an interponent movable into'and out of position, to support the cylinder either in its upper or printing positionior in its lower on non-printing position. As shown, the movable stops comprise two arms 61, 'at either side of the sliding frame 56 and each pivoted thereto at 62. I v

The cooperating stop, which also provides in this embodimest the regulation or .ad-

justrnent for the printing pressure or squeeze, comprises a lug 63 onthe press frame, which is internally screw-threaded.

Threaded the'reinto is a .bolt 64, having locking nuts 65 and'66 operating on either. side of lug 63. A corresponding device is on each side of the press, and by turning the'bolts 64 at either side. the squeeze or printing pressure of cylinder 3 is exactly determined or adjusted. I

By swinging arms 61 outwardly as shown in F ig'. 7, cylinder 3- may be lowered by turning shaft 60 to the position shown in that figure, .and plate cylinder 1 moved up to print directly on'the web or to print on cylinder 4 as an offset cylinder. The remaining parts of the press may be substantially as already described.
