GEORGE E. RUNYON, OF KANSAS CITY, KANSAS, ASSIGN'OB OF ONE-HALF TO GLEN I HAZEL, OF KANSAS CITY, KANSAS.

ROLLER BEARER.

Application filed February 20, 1922. Serial No. 537,757.

To all whom it may concern:

Be it known that I, Gnonon E. RUNYON, a citizen of the United States, residing at Kansas City, in the county of Wyandotte and State of Kansas, have invented certain new and useful Improvements in Roller Bearers, of which the following is a specification.

My invention relates to roller bearers adapted to be applied to printers chases for the purposes of supporting the ink distribut ing rolls of the printing press type-high during their travel over the form locked up in the chase.

Heretofore, it has been customary to support the distributing rolls by the metal rollers at each end thereof. Said metal rollers travel on thetracks forming part of the press and have sufficient traction to drive the associate distributing rolls. Under favorable temperatures this old method is more or less satisfactory, but when the relatively sensitive distributing rolls are subjected to changes in temperature which 1 cause them to expand or contract and thus become larger or smaller diametrically than the metal rollers, too much or too little ink is applied tothe type and results in unsatisfactory printing.

By the use of my invention the d1stributing rolls are held type-high while traveling over the form, irrespective of diametrical variations and said distributing rolls have sufiicient traction on the roller bearers constituting the present invention, to prevent slippage and consequent uneven distribution of the ink upon the type.

A further feature of the invention resides in the fact that my roller bearers are applied to the outside of the chase instead of being locked up with the form, and hence just as soon as the chase is removed from the press the roller bearers can be removed instead of waiting for the form to be removed from the chase, where it sometimes remains for several days. Thus a less number of roller bearers are required in the printing shop.

Other features will hereinafter appear, and in order that the invention may be fully understood, reference will now be had to the accompanying drawing, in which:

Fig. 1 is a plan view of a chase equipped with my roller bearers upon which two of the distributing rolls are mounted.

Fig. 2 is a fragmentarycross section on l1ne II-II of Fig. 1.

Fig. 3 is a side elevation of the chase with the roller bearers in position thereon.

roller bearers 2, which are removably applied to the opposite ends of the chase A to hold the distrilouting rolls D type-high.

Each roller bearer 2 consists of a rail 4 tapered at its ends as indicated at 6, so that the distributing rolls D can readily mount and leave the track formed by the rails 4.

Each rail 4 is equipped adjacent to its ends with holders 8, which are substantially C- shaped in cross section to snugly engage the top, bottom and outer surfaces of the end bars Gr of the chase A, as shown more clearly by Fig. 2. The holders 8 may be secured to the rails 4; in any suitable manner. In the drawings I have shown their upper portions countersunk in the lower portions of the rails 4 and firmly secured to the latter by screws 10.

In practice the roller bearers 2 are applied to the outside of the bars G of the chase A, instead of being locked up with the form B and the parts are so proportioned that the upper surfaces of the rails 4c are type-high, so that when the distributing rolls D travel on said rails 4 they will be supported type-high irrespective of any diametrical changes which may have occurred due to changes in temperature, and hence uniform distribution of the ink upon the type is assured.

When the chase A is removed from the printing press the roller bearers 2 can be slipped off the ends of said chase A without waiting for the removal of the form B, and applied immediately to another chase ready for the press.

From the foregoing description it will be understood that I have provided simple devices which are well adapted for the purpose intended, and while I have shown and described the preferred form of my inven tion, I reserve the right to make such changes as properly fall Within the spirit and scope of the claim.

Having thus described my invention, What v5 I claim and desire to secure by Letters Patent, is:

An attachment for printers chases consisting of a pair of rails adapted to lie on top of the end bars of said chase, and holders of substantially C-shape in cross section 10 fixed to said rails to removahly secure the same to the chase.

In testimony whereof I affix my signature in the presence of two Witnesses.
