Specification of Letters Patent.

To all, whom, it may concern.-

Be it known that we, CHARLES H. PALMER and JOHN W. DENMEAD, of Akron, in the county of Summit, and in the State of Ohio, have invented certain new and useful Improvements in Printing-Presses; and we do ereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which- Figure 1 is a side elevation of a multicolorprinting press embodying our invention.

ig. 2 is an end elevation thereof. Fig. 3 is a detail View, in side elevation, on a larger scale, of one of the form-cylinder mechanisms; and Fig. 4 is a detail view in section ofone of the form-cylinder bearings.

Letters of like name and kind parts in each of the figures.

The object of our invention is to provide a printing-press of such construction as to greatly facilitate the work of assembling its parts, to enable the forms to be moved rela tive to the impressionecylinder for both avoiding printing on the blankets andqiermitting adjustment for accurate register, and to enable the inking-rolls to be lifted from the forms to avoid injury to the inking-rolls when they are not in use and to these ends our invention consists in the printing-press having the features of construction substantially as hereinafter set forth.

We illustrate our invention as embodied in a color-printing press of usual general construction that is. it comprises a frame A, an impression-cylinder B, and a series of form-cylinders O and C, grouped around said cylinder. The frame A com rises a base and two side pieces that are bolted to the refer to like base, and in each side pieceis a box or bearing D for the shaft E, on which the impression-cylinder B is mounted. Each frame side is fori'ned of two parts that are joined on a horizontal plane passing just above the bearings of the shaft E, each shaftbearing D being placed in a cavity in the upper art of the lower section of the frame side, w ch is covered by the bottom of .the upper section of the frame side. It will be apparent that with this construction of frame the Work of assembling is rendered very convenient and easy, because the work of mountingthe large impression-cylinder can be done without the hindrance that would be occasioned by the necessary presence of the upper side section were it an integral part of the lower section. To give as com lete access as 0881- ble to the parts inside the frame, the ame sides are, as shown, of open-work construction.

For driving the impression-cylinder it has 'a large gear F, that meshes with a gear G on a driving-shaft H.

For each form-cylinder there is a shaft I, and upon the latter is a gear J, that meshes with and receives motion from the impression-cylinder gear K. Said shaft I is ournaled at opposite ends in boxes L and L, that are respectively mounted in openings in arms or brackets a and a on the two frame sides, which openings in a direction radial to the impression-cylinder axis arelonger than the boxes, so that there may be bodily movement of the form-cylinder to and from the im ression-cylinder. The form-cylinder is he (1 yieldingly at the inner limit of its motion by means of a spring M, interposed be- .tween the outer end of each box and a screw a. At its inner end the box is engaged byv the ends of two screws 0 and O, that fix its inward movement. Two screws 0 and O are provided for each box, so that should it be necessary to move the cylinder outward-as, for example, to disengage the cylinder-gear from the gear F to free that cylinder for adjustment for securing perfect registersuch can be done Without its being required to again adjust it, one screwin such case being used'to force the box outward and the other being undisturbed, so that on the return of the cylinder to its inward position the undisturbed screw will arrest it at the same place it previously occupied.

J ournaled on a round projection Z on each box L concentric with the cylinder-shaft is a rocking plate P, that has a peripheral camsurfaoe p, which engages a projection or roller Q on the side of the box bracket e and which when moved in one direction acts to move the box and cylindcroutward against the pressure of the spring and when moved in the opposite direction permits the spring to act to restore the former position of the parts. The outward movement of the cylinder by action of the cam is not sull'icient to disengage the gears J and K, but is only sufl cient to prevent rinting by the cylinder, and is provided to 0 sviate printing on the blanlrets when no paper is run through the press.

For rocking the cam p'late I it has an arm ,1), and to enable all of the groups of formcylinders to, be simultaneously operated the series of arms on the same side of the press are connected to ether by links R and R and the end one of t is series on one side is connected by a link S to an operating-lever T, that is secured to a shaft U, mounted in bearings on the frame sides and extending across the press from side to side. The familiar device of a notched segment and dog is provided for locking the lever at each limit of its swing to secure the form-cylinders in one or the other of their positions, It will be understood that the cam-plates and the link colinections are on both sides of the press and that the series of cams on the side that does not have/the operating-lever is connected to the shaft U, so that both series may be operated by the one lever.

For each form-cylinder there is an'inlr-fo'untain V of common construction, from which ink is taken and transferred to the form by a series of rolls. The main distributing-roll W of each inking apparatus is fixedly mounted in hearings on extensions or brackets on the frame sides; but the other rolls X and X are iournaled in a frame Y, that is hin ed at one extremity by a pivot Z, so that tie frame, with said rolls, may be swung outward on the pivot away from the main distributing roll and the lorm-cylinder. Attached pivotally to the free extremity of the frame Y is pne end of a bar or link A, whose other end has a pin or stud a which en ages a notch or ooen ended slot in the cam-p ate P,'so that by the rocking of the latter the roll-carrying i'ralne may be moved. When the cam is rocked to shift the cylinder from contact with the im ressioncylinder, the inking rolls are simu taneously lifted from the form'- cylinder, and on the return of the form-cylinder to printing position the inking-rolls are restored to contact with the form-cylinder. It will thus be seen, too, that the single operating-lever controls the movements of both all of the form-cylinders and all of the movable inking-rolls. Should it be desired to move the inking-rolls independently of the movement of the form-cylinders, this can be done by reason of the pin-and-slot form of connection between the bars A and A and the cam-plates P and P. A-rod B connects the two frames Y and Y of the same mechan- ISIIl. I

By mounting the inking-r0lls X and X in movable frames the rolls which have contact with the form-cylinders can be lifted out of from resting on the irregular type-surfaces obviated. The supply of ink to the mam distributing and the form cylinders is stopped when the latter are not printing, and access I to said cylinders for cleaning or other purposes can be readily load without disturbance of the working position of the inking-rolls in their bearings. .i

The doctor-roll D is vibrated by a cam E on the form-cylinder shaft, which acts on a roll F on a yoke G, that is connected with the doctor roll-carrying frame H Having thus described our invention, what we claim is l 1. In a printing-press, the combination of the imcressiomcylinder, a form-c linder, a moveb e bearing for the latter, a p urality of independentlyedjustable stops for said hearing, and yieldin means for automatically pressing said bearing against said stops.
