Patented May 2, 1939 UNITED STATES PATENT OFFICE ROLLER SIDE BEARING Arthur B. Severn, Pittsburgh, Pa., assignor to 10 Claims.

The invention pertains to roller side bearings for railroad cars and particularly of the type in which the roller can be readily adjusted in a vertical direction relative to the bearing.

An object of the invention is to provide a roller side bearing with a movable shim or stepped roller support, which upon movement relative to the roller raises or lowers the roller within the bearing.

Another object of the invention is to provide such an adjusting means which is readily accessi-ble; easily operated, and may be securely held inany position of adjustment.

Heretoiore man-y adjustable sidebearings have Each of them contemplated raising or removing the roller before removing or inserting shims beneath the roller boa-ring plate. Such an operation required the car inspector or other person making the adjustment to carry a supply of suitable shims and also means to raise the car body to permit removal or raising of the roller. In the present invention there is no necessity for adding or removing parts of the roller bearing. No special tools are necessary to raise or lower the body to permit adjustment. The only tool necessary is. a hammer which every workman or inspector carries. and he need only strike the stepped support plate with the hammer to effect the adjustment. By: making this stepped support plate separate from the bearing plate for the roller all adjustments. can be made without removal of the roller or other parts of the bearing.

In. the drawings forming part of the specificay tion:

Fig. 1'. is a plan View of a roller bearing, disclosing. the. invention; Fig. 2 is a section.- taken on lines 2 -2: of Fig. 1; Fig. 3 is a half end elevation. and half section taken on the, lines 3-3 of Fig. 1;; Fig. l is a plan view of a bearing. contai-ning' a modification of my invention; Fig. 5 is section taken on lines 5-5 of Fig. 4; Fig. 6 is a. View showing half in end elevation and half in: section: of the lines of Fig. 4.

Referring now to Figs. 1. to 3 inclusive of the drawings, reference character l shows a portion of a railway car truck bolster having an integral pocket formed on the upper face thereof comprising side walls 2 disposed transversely of the. bolster and connected at their end portions by end walls 3 to complete the pocket. Interiorly of the pocket and at each corner thereof are lugs 4 of less vertical height than the walls 2 and 3 for a purpose hereinafter-to be described.

Eachend Wall 3 has an aperture 5 therein extending upwardly from the base of the wall for a portion of the height of the wall and as shown in the drawings is preferably of a width equal to the spacing between the lugs 42. These apertures are for the purpose of making the bearing self-clearing as hereinafter set forth. Each side wall 2 of the body has apertures 6 therein extending upwardly from the base thereof and of a width substantially equal to the spacing between the lugs 4.

Disposed longitudinally of the bolster I and upon the upper face thereof is a stepped bearing member extending transversely of the pocket through the apertures 6 in the side walls 2. This stepped bearing member 1 has an end portion 8 of a depth and width substantially filling the aperture 6' in the pocket side wall 2. An upper face 9 is provided with a series of steps extending transversely thereof and reducing the depth of the member I in a direction longitudinally thereof. This stepped portion of the upper face 9. is of a length sufficient to extend beyond the pocket side wall 2 At the end of the bearing member 7 and in spaced relationship to the pocket side wall 2 is. an integrally formed upwardly extending portion l having a plurality of vertically spaced apertures ll) therein which extend transversely of the member I. Extending. outwardly from the pocket side wall 2* and on opposite sides of the member T are vertically disposed Walls ll of a height substantially equal to the vertical height of the portion l of the member T and having apertures I2 therein, these apertures being so spaced as to register with one or the other of the vertically spaced apertures N! as the member l is advanced within the pocket a distance equal to the width of one of the stepped bearing surfaces of the upper face 9 of the. bearing member 1?.

Disposed within the pocket and within the restricted area of the pocket as formed by" the corner lugs t is a roller bearing plate l3. The bottom of the bearing plate has steppedhearing faces therein corresponding to the upper face of the member 1 and is supported thereon; The upper face of the member 23 is concave in a direction transversely of the bolster and longitudinally of the pocket side walls 2. Disposed within. the pocket and upon the bearing plate i3 is a roller I l moving longitudinally of the pocket side walls 2' and of a diameter so that the periphery of the roller extends above the walls 2 and 3 of the pocket. As is usual in this type of bearing the roller forms a bearing for a wear plate i5 secured on the underf'ace of the body bolster indicated at It.

For the purpose of reinforcing the side wall 2 a beading H is. disposed on the outer face of the side wall. 2 around the aperture 5. therein.

In assembling the bearing the stepped bearing member 1 is inserted in the apertures of the pocket side walls 2. and moved longitudinally of the pocket until the endportion 8' extends pastthe inner face of the side wall 2. The roller bearing plate 13 is placed within the pocket on the member I and thereafter the roller [4 is inserted. A bolt I8 is passed through the registering apertures l and I2 of the portion 1 of the member l and the walls ll respectively as shown in Fig. l of the drawings thus locking all parts in position. When it is desired to lower the roller within the pocket the bolt I8 is removed and the portion 1 struck with a hammer advancing the member 1 one or more steps as desired and the bolt l8 replaced to again lock the member 7 in position.

By reason of the roller bearing plate l3 stopping short of the end walls 3 of the pocket an opening I9 is formed therein through which dirt or other debris can fall during the operation of the bearing and pass out of the pocket through the apertures 5 in the end walls 3. This feature makes the bearing self-clearing and prevents it being clogged during operation.

From the foregoing it will be obvious that considerable labor is saved in the adjusting operation. With the ordinary type bearing it is necessary to remove the car from service, place jacks upon the ends of the body bolster, raise the body a sufficient distance to permit removal of the roller and bearing plate in order to insert or remove shims but with the present invention the only tool needed is a hammer and the adjustment can be effected as set forth without removing the car from service.

Referring now to Figs. 4, 5 and 6 of the drawings, the invention is shown in a modified form adapted for use in that type of bearing in which a separate pocket is fastened to the upper face of the bearing. In these figures, reference character l indicates a portion of a railway car truck bolster having mounted on the upper face thereof and adjacent each end a casting comprising side walls 20 disposed transversely of the bolster and connected at one end by an end wall 2| and intermediate the ends by an end wall 22 to form a pocket. At each corner of the pocket and extending upwardly from the base thereof are lugs 23 which are of less vertical height than the side walls 20. The pocket end walls 2! and 22 have apertures 24 therein extending upwardly from the base of the wall to substantially the height of the lugs 23 and of a width substantially equal to the space between said lugs. The pocket side walls continue beyond the end wall 22 and are of less vertical height to form guides for a purpose hereinafter set forth.

Upon the upper face of the bolster and extending longitudinally of the pocket is a stepped bearing member 25 having an inclined upper face formed of a series of stepped fiat bearing surfaces extending transversely of the member 25 and upon which is supported a roller bearing plate 26 disposed within the pocket and between the lugs 23. At the thicker end of the member 25 is an upwardly extending head 25 and extending transversely of the member 25 as such thickened portion and adjacent the head 25 are apertures 27. Each of the pocket side walls 20 have suitably spaced apertures 28 therein to receive the belt 29 for locking the stepped bearing member 25 in position. For the purpose of securing the pocket casting to the bolster suitably formed lugs 30 are formed thereon and are riveted or bolted to the bolster by means of suitable fastening members.

As in the previously described embodiment of the invention the apertures 24 in end wall 2i provide for the removal of debris collected during the operation of the car and in order to remove Water or other debris which may form on the bearing plate 25, apertures 3| are preferably formed in the pocket side walls 20 intermediate the end walls 2| and 22 and adjacent the upper face of the bearing plate 26.

As in the previously described embodiment of the invention, the roller 32 is mounted within the pocket and upon the bearing plate 26 and vertical adjustment for the roller is provided by moving the stepped bearing member 25 transversely of the bolster. By providing a plurality of apertures 21 in the member 25 and spacing the apertures 28 intermediate the apertures 21 in the member 25, excepting for the registering apertures in walls 20 and member 25 adjacent the roller bearing plate 26, one of the apertures in the member 25 will always coincide with one of the apertures in the walls 20 regardless of the position of the member 25in making adjustments.

As in the previously described exemplification of the invention, but one tool is necessary to effect vertical adjustment of the bearing, it being obvious that it is only necessary to remove the bolt 29 and strike or pry the head 25 toward or away from the end wall 22 of the pocket the desired distance before reinserting the bolt 29.

The drawings and specification disclose what is now contemplated as the preferred forms of my invention. Many changes in the details of construction will suggest themselves to those skilled in the art and it is to be understood I do not wish to limit myself to the exact forms of the invention as disclosed except as necessitated by the scope of the appended claims.
