HARRY S. BROOKS, OF ELMIRA, NEW YORK.

APPARATUS FOR PRINTING IN COLORS.

SPECIFICATION forming part of Letters Patent No. 444,231 dated January 6, 1891.

Application filed June 11, 1890. Serial No.355,082. (No model.)

To aZZ whom it may concern.

Be it known that I, HARRY S. BROOKS, of Elmira, in the State of New York, have 'invented new and useful Improvements in Apparatus for Printing in Colors, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

My invention relates to machinery and appliances for printing colored work on a webperfecting press running at high speed, whether for printing lines of the same or different colors, or for printing signs, emblems, or patterns, printing lines and emblems. &c., all simultaneously and in unison, and without conflicting.

My object is to produce an apparatus by which I can embellish the pages of a newspaper printed upon a welrperfecting press running at the highest speed with vertical, horizontal, or parallel lines of different colors, and also with signs, emblems, 0r patterns of the same or of different colors arranged in Vertical longitudinal parallel lines, or other shapes and designs.

My invention consists in the several novel features of construction and operationhereinafter described, and which are specifically set forth in the claim hereunto annexed.

It is constructed as follows, reference being had to the accompanying drawings, in which Figure 1 is a side elevation of my apparatus, showing also its relation and mounting as to the impression and type cylinder. Fig. 2 is a top plan view of the same.

A is a tank for holding fluid ink, and it is divided into compartments a I) 0 cl 6, each for holding different colors, and each compartment may be subdivided to give more range of colors or more variety, &c., as hereinafter explained.

Each compartment is provided with a dis charge-gate 1, and 1 is a rod connected to the gate for adjusting and regulating such discharge by opening or closing the gate. These compartments discharge the ink upon an ink-roller 2, and 3 is an ink-distributing roll maintained in frictional contact with the roller 2 by a spring 4 behind the box 2 upon the arbor 2 at either end of the roller, said box being mounted and adapted to slide in a horizontal slotway 5 in the frame 6, and 7 is an adjusting-screw to regulate the tension of the spring. The roll 3 is also adjustable vertically by means of the spring 8, bearing upon the box 3", carrying its arbor 3 ateither end, said box being mounted in a Vertical slo-tway 8 in the frame, and movable therein and regulated by a set-screw 9.

B is my roll for printing the lines, signs, symbols, emblems, or patterns separately, consisting of different printing cylinders or rolls 10, 11, 12, 13, and 14 of any width desired, all of the same diameter and mounted upon a common shaft 1) and adjustable thereon in an ordinary manner to vary the location of each or the distance between any two of them. The periphery of each roll is properly engraved by any process with the copy of the sign, symbol, or emblem which I desire to imprint upon thepaper, or some can be so engraved and others adapted by being made thin to imprint lines upon the paper. All of these rolls are supplied with ink from the roll 3, and this roll is also in frictional contact with t em. The shaft b of these rolls is mounted at either end in a bearing 17, inserted into a mortise b in the front edge of the frame, and held removably therein by the cross-bar 15 and screws 15.

O is the im pression-cylinder over which the web passes, and the prlnting-rolls are all in contact with and are rotated by its rotation, so that the web is impressed or imprinted with all of the different lines, signs, symbols, &., represented by the different rolls simultaneously and before the web reaches the type-cylinder D.

WVhat I claim as my invention, and desire to secure by Letters Patent, is

The combination of the ink-tank having a discharge-gate, the frame supporting the inktank, each having a horizontal slotway, a vertical slotway, and a mortise, the ink-roller having arbors, boxes in which the arbors rotate, located in the horizontal slotways, the springs pressing against the boxes, the inkdistributing roll having arbors, boxes for the latter located in the vertical slotways, the springs pressing on the vertical boxes, the printing-roll, having a shaft, and bearings for the latter located in the mortises, substantially as described.

In Witness whereof I have hereunto set my hand this 22d day of May, 1890.

' HARRY S. BROOKS.

In presence of- RICHARD H. THURSTON, HOWARD P. DENISON.
