ROLLER ADJUSTMENT FOR PRINTING-PRESSES.

Application filed August 30, 1917.

To all whom it may concern Be it known that we, SIDNEY M. VVEATH- ERLY, a citizen of the United States, residing at Hartford, Hartford county, and State of Connecticut, and HOWARD J. STAcH, a citizen of the United States, residing at Hartford, Hartford county, and State of Connecticut, have invented and discovered certain new and useful Improvements in Roller Adjustments for Printing-Presses, of which the following is a specification.

Our said invention relates to journal bear ing adjusting and locking devices and consists in the combinations and arrangements of elements hereinafter described and particularly set forth in the accompanying claims.

The invention has for its purpose to provide a journal bearing adjusting and looking means which is readily accessible for adjusting the separate parts without interfering with the adjustments to be malntained; and whepein the several elements may be set up or taken down in a quick and easy manner.

The invention is designed with special reference to printing presses, to enable the pressman to regulate the pressure of the composition distributer roller against the ink cylinders, and also to regulate the pressure of the steel vibrator roller on the com position roller, to the end of preventing "the composition roller from heating up and melting from friction, and also to improve the distribution of the ink.

Heretofore the journals of the composi tion distributer roller and the steel vibrator roller were fioatingly mounted in the slots of the roller carriage-way, and gravity carried the composition distributer roller against the ink cylinder with its full weight,

and this, with .the weight of the steel vibrator which rides on the composition roller,

caused excessive friction and resulted in heating up the composition distributer roller, with the result that the same softened or melted and would run down. And 1t 18 to avoid these disadvantages that the ar- Specification of Letters Patent.

Fig. 2 a sectional view, taken on the line 22 of Fig. 1.

Fig. 3 a side elevational view of a modified construction, partly broken away, and

Fig. 4 a sectional view, on the line H of Fig. 3.

Referring to the construction in further detail, and with like reference characters representing corresponding parts in the different views, 6 designates the frame of the press, constructed with the usual pair of guide-ways 7, and having a large ink cylinder 8 and a small ink cylinder 9 journaled in said frame, after the usual manner. A composition distributer roller 10 has the shaft 11 thereof journaled in the journal boxes 12 (one being shown) that are slidably mounted in the guide-ways 7; and a vibrator roller 13 has its shaft slabbed as at 14, and slidably mounted in said guide-ways as shown.

The pressure regulating and locking device, to which this invention pertains, has reference to the composition distributer roller and the vibrator roller, and the means therefor consists of similar devices carried by said rollers within each guide-way, and those on one side only will be described.

The journal box 12 carries a screw 15 threaded therein, and said screw has an angular head 16 adapted to fit closely within the guide-way 7- and against the frame at the lower end thereof, in such a manner as to prevent turning after being set. In mounting the composition roller in the frame, the screws 15 are first adjusted and the roller is then set. into the slots or guide-ways, with the heads 16 of the screws resting upon the flat bottoms of the slots and the composition roller in contact with the ink cylinder for its relatively large heads 18, of square design in cross-section, for fitting within the guide- Patented Apr. 20, 1920.

ways 7, to be held against turning, as will 7 or plate that fits snugly within notches 21 formed in the frame adjacent the entrance opening to the guide-way 7 The screw is provided with a knurled head 22 for regulating and firmly holding the entire adjusting mechanism, including the vibrator and composition rollers, after the manner stated.

The arrangement shown in Figs. 3 and 4 difiers from the construction above described, in that the adjusting screw 15 of the distributer roller has a round head 23 provided with apertures 24 to receive a suitable instrument for turning the screw to obtain the desired adjustment of said roller without requiring the removal of the roller from the guide-ways. In like manner, the adjusting screw 17 of the vibrator roller has a cylindrical head 25 provided with openings 26 for the purpose of adjustment. In all other respects, the construction, arrangement and manner of adjusting and locking the parts shown in Figs. 3 and a, are the same as that of arrangement shown in Figs. 1 and 2.

The adjusting screws 15 and 17 are respectively provided with round lock nuts 27 and 28 having apertures for adjustment, and said nuts bear against the ournal boxes 12 and slabbed ends 14: for locking the screws 15 and 17 in their adjusted positions even if the vibrator and distributer rollers are removed fromslots 7 Similar lock nuts 27 and 28 are provided for the adjusting screws 15 and 17 shown in Figs.

g It is obvious that those skilled in the art may vary the details of construction and arrangement of parts without departing from the spirit of our invention, and we therefore do not wish to be limited to such details except as required by the claims.

Having thus fully described our said invention what we claim as new and desire to secure by Letters Patent, is

1. In a printing press, means for adjusting the distributer roller, the ink cylinder and the vibratorlroller in definite relation to each other and securing them positively in such relation, comprising a frame having guide-ways, an inkcylinder journaled adjournal members mounted to slide in each of said guide-ways, the distributer cylinder journaled in said journal members, adjusting screws interposed between said journal members and the frame, another set of journal members mounted in said guideways, a vibrator roller mounted to operate thereon, adjusting screws interposed between the first journal members and the second journal members at each end of the frame, and clamping screws mounted in supports on said frame and adapted to bear against said outer ournal members, whereby said several parts may be adjusted to bring said ink cylinder, distributer roller and vibrator roller into definite-position in relation to each other and lock them in such position, substantially asset forth.
