SIDE BEARING.

UNITED STATES PATENT OFFICE.
WILLIAM A. BOOK, OF CHICAGO, ILLINOIS, ASSIGNOB TO WILLIAM H. MINER, OF
CHAZY, NEW YORK.
SIDE BEARING.
Application filed April 3, 1919.
To all whom it may concern Be it known that I, WILLIAM A. Boon, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Side Bearings, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.
This invention relates to improvements in anti-friction bearings.
The object of the invention is to provide an anti-friction roller bearing of simple and inexpensive construction and more especially adapted for railway cars.
In the drawings forming a part of this specification, Figure 1 is a vertical, sectional view taken through the ends of a car body and truck bolster, showing my improved bearing in the form of a side bearing. Fig. 2 is a top plan view of the side bearing shown in Fig. 1. Fig. 3 is a vertical sectional View taken substantially on line 3-- 3 of Fig. 2.
In said drawing, 10 denotes the under portion of a car body bolster and 11, the upper portion of the corresponding truck bolster. In the drawing, I have shown my improved side bearing secured to the truck' bolster and as shown, the side bearing employs a casing or base casting A and an antifriction roller B.
The casing A, as shown, is of substantially hollow, rectangular form and has end walls 1212, side walls 13-13, bottom wall 1 1, and corner perforated lugs 15-15 by which it is adapted to be riveted to the bolster. In order to increase the life of the bearing, the lower wall of the casing A is provided with a steel insert, as indicated at 16, said insert forming the bearing surface for the entire friction roller B.
The roller B is of cylindrical form and has an axially extending opening 17. Seated within this opening 17 are two plungers 1818 and an interposed spring 19. The ends of the plungers 18 are made substantially spherical as indicated at 20 and work in longitudinally extending, opposed converging grooves or channels 2121 in the opposed faces of the side walls 1313 of the casing A. Said grooves or channels 21 are curved in cross section to better cooper- Specification of Letters Patent.

roller with the casing A, the side walls of the casing A are slightly cut away 011 an incline as indicated at 22, so as to permit the plungers 18, carried by the roller B, to he slipped vertically downwardly within the casing A.
As will be noted by an inspection of Fig. 2, the opposed sets of converging grooves 21, are so arranged that the maximum space between bottoms of said grooves occurs in alinement with the axis of the roller B, when the latter is in central normal position. Consequently, when the roller B is moved to either side of normal, the plungers 18 will gradually be forced inwardly of the roller B, as said plungers travel along the inclined grooves 21. When the actuating pressure is removed from the roller B, the spring 19 will then act upon the plungers 18, forcing the latter outwardly and consequently compelling the roller B to return to its central normal position.
The arrangement is simple and all the parts may be cheaply manufactured and all parts assembled before application to the car.
I claim:
1. In a roller bearing, the combination with a retaining member, of an anti-friction roller adapted to roll back and forth with respect to said member, the latter having upstanding side walls opposite the ends of said roller, the inner faces of said walls being formed with opposed sets of longitudinally extending converging grooves having the maximum distance between said grooves in alinement with the roller when the latter is in normal position, and axially movable spring contained plungers, carried by the roller and cooperating with said grooves to return the roller to normal position after actuation thereof.
2. In a roller bearing, the combination with a hollow retaining member, having side walls provided with inclined grooves on their inner faces, of an anti-friction roller, movable back and forth within said memher, said roller carrying axially disposed spring pressed plungers adapted to have their ends project within said grooves, the
ends of said plungers being rounded and said grooves being correspondingly curved to engage said plungers.
3. In a bearing, the combination with a hollow retaining member having side walls, the latter on their inner faces being provided with inclined channels, of an anti-friction element, spring controlled plungers carried. by said element and cooperable with said channels, said element and plungers carried thereby, being insertible from the top of the retaining member.
4. In a roller side bearing, the combination with a retaining member having side, end and bottom walls, the inner faces of the side walls being provided with opposed sets of longitudinally extending converging grooves of an anti-friction roller mounted in said member, said roller having an axially extending opening and spring mounted within said opening and plungers at the ends of said spring, normally projecting beyond the ends of said roller and cooperating with said grooves to efl'ect return of the roller to normal position after each actuation thereof.
In witness that I claim the foregoing I have hereunto subscribed my name this 25 day of Feb. 1919.
WILLIAM A. BOOK.
