CARL F. EOKMAN, OF CHICAGO, ILLINOIS, ASSIGNOR OF ONE-HALF TO E. T. NAYLOR, OF MELROSE PARK, ILLINOIS.

INK-DISTRIBUTER FOR PLATEN PRINTING-PRESSES.

SPECIFICATION forming part of Letters Patent No. 792,652, dated June 20, 1905.

Application fi ed September 2, 1903. Renewed March 8, 1905. Serial No. 249,121.

To all whom it may concern.-

Be it known that I, CARL F. EOKMAN, a citizen of the United States, residing at Ohicago, in the county of Cook and State of Illinols, have invented certain new and useful Improvements in Ink-Distributers for Platen Printing-Presses, of which the following is a specification.

This invention relates to an ink-distributer for platen printing-presses. Heretofore considerable difliculty has been encountered in obtaining an even distribution of ink upon the printing-form, and when a large printingform is used it is necessary to double roll the formthat is, run the press two revolutions for one impression-so as to evenly distribute the ink over the printing-form.

This invention is designed to overcome the above objection, and I therefore provide an apparatus which may be easily secured to platen printing-presses and which is adapted to evenly distribute the ink over the printing-form, thus obviating the necessity of double-rolling the printing-form.

My invention is illustrated in the accompanying drawings, in which-- Fi ure 1 is a side elevation of my improved inkistributer for platen printing-presses. Fig. 2 is a front elevation with portions broken away, and Fig. 3 is a perspective view of the auxiliary socket detached.

Referring to the drawings, 1 indicates a roller-bearing frame, 2 the form-rollers, and 3 the roller-sockets, which are slidably mounted in the roller-frame 1. One of the sockets 3, preferably the intermediate socket, is provided with the openin 4.

5 indicates an auxiliary socket, which is provided with a spring supporting rod 6. This spring-supporting rod is passed through opening 4 in socket 3 and opening 1 1 in frame 1, and a spiral spring 7 is passed around the protruding end thereof. The spring 7 is held in position on rod 6 by means of the washer and key 8. When the auxiliary roller 9 is in the auxiliary socket 5, the spring 7 will normally hold the auxiliary roller 9 in contact with rollers 2.

10 indicates a key, which holds the auxiliary roller 9 in position in the auxiliary socket 5.

12 indicates a projecting arm rigidly secured to socket 3. This projecting arm is adapted to bear against the shaft 13, and when socket 3, carrying roller 2, slides forward in the frame 1 the auxiliary roller 9 will also be pushed forward, thus always keeping auxiliary roller 9 normally in contact with rollers 2.

In operation the roller-bearing frame 1, carrying the form-rollers 2, passes over the ink-cylinder, (not shown,) thus distributing the ink upon the form-rollers 2. The auxiliary roller 9 is so arranged as to normally be held in contact with the form-rollers 2. When the form-rollers 2 are rotated, the auxiliaryv roller 9 will also rotate, thus evenly spreading the ink over the surface of the form-rollers 2, and as the form-rollers 2 pass over the printing-form the ink will be uniformly distributed over the entire surface of the printing-form.

Slight changes can be made in the eneral form and arrangement of the several parts described without departing from the spirit and scope of my invention. Hence I do not wish to be limited to the exact construction herein set forth.

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

1. In combination with the roller-bearing frame, the roller-sockets and the form-rollers carried thereby, of an ink-distributer comprising a supporting-rod, one of the rollersockets and the said frame having alining apertures formed therethrough, said rod being spring-pressed and extending through the said apertures, an auxiliary socket on the end of said rod, with an auxiliary roller mounted therein, means for retaining said roller in said auxiliary socket, and a projecting arm secured to one of the said sockets and having an upwardly-extending portion to be engaged by the shaft of the auxiliary roller, said arm limitin the inward movement of the auxiliary rdller.

2. In combination with the roller-bearing frame, the roller-sockets and the form-rollers carried thereby, of a rod passing through alining apertures formed in the said frame and one of said sockets, a spring surrounding the rod and bearing against the frame, a nut on the rod at the outer end thereof engaging the spring, an auxiliary socket carried on the opposite end of the rod, an auxiliary roller having the shaft thereof mounted in said socket, means for retaining the shaft in the 10 socket, and an arm carried by one of the sockets for limiting the inward movement of the said auxiliary-roller shaft.

In testimony whereof I have signed my name in the presence of two subscribing Witmesses.

CARL F. ECKMAN.
