WILLIAM E. WINE, OF TOLEDO, QHIO.

v SIDE BEARING.

Application filed February 3, 1923. Serial No. 616,672.

To all whom it may concern:

Be it known that WILLIAM E. "NINE, a citizen of the United States of America, residing at Toledo, in the county of Lucas and State of Ohio, has invented certain new and useful Improvements in Side Bearings, of which the following is a specification.

My invention relates to new and useful improvements in side-bearings, and in general to the well-known WVine side-bearing, and more particularly to the housing which supports and retains the roller.

One of the principal objects of the present invention is to form a housing which is relatively light in weight, though rigid in construction; in which there is placed a reversible wear-plate, which wear-plate in turn, is provided with rivets, the opposite ends of each of the rivets being similarly headed, and the housing further formed to receive the heads of the rivets which are downwardly disposed when the wear-plate is in position.

As is well-known to those familiar with the art, the Wine type of self-centering sidebearing comprises a housing in which there is a self-centering roller and beneath the roller and secured to the housing, is a wearplate, the securing means being in the form of rivets, the heads of which project upwardly to fit within depressions formed in the roller as the roller functions within the housing, thus preventing a longitudinal slipping of the roller when in action.

I have found in practice that the wearplate after long and hard usage becomes irregularly worn, thus presenting an irregular surface to the lower portion of the roller and thus changing its center. Likewise the rivet heads become worn and allow the hearing to shift longitudinally, which may mean that a lesser area of the roller bearing will be presented to the wear plate of the body bolster than is desired.

It was therefore necessary, when the wearplate became worn, to renew the entire housing or cut out the rivets and insert a new wear-plate and substitute new rivets. F urthermore, if a wear-plate was so constructed that the rivet heads simply loosely protruded through the same, the wear-plate could be reversed, but as the heads of the rivets also wear and become out near their base, they would fail to perform their aligning function with the roller and would have to be constantly renewed.

In the present application, therefore, I

have provided a reversible wear-plate in which rivets have been secured, which rivets, in turn, are similarly headed on their opposite ends, while in the base of the housing is formed openings for the reception of the downwardly disposed rivet heads. Therefore, when a new surface of the wear-plate is disposed to the roller, likewise, new rivetheads are disposed to the roller.

The openings formed in the base-plate of the housing are tapered to correspond to the angularity of the rivet heads, and the diameter of the opening is slightly greater than the greatest diameter of the rivet heads so that the plate may be quickly and easily reversed, but when once placed within the housing will be prevented from any shifting movement With the above and other objects in view, the invention consists in certain new and novel constructions and combination of parts as will be hereinafter more fully described and pointed out in the claims.

Referring now to the drawings showing a preferred embodiment of the invention,

Fig. 1 is a longitudinal section of the housing, the roller being shown in dotted lines;

Fig. 2 is a transverse sectional view taken on line 22 of Fig. 1; looking in the direction of the arrows;

Fig. 3 is a sectional view taken on line 3-3 of Fig. 1, looking in the direction of the arrows; and

Fig. 4 is a perspective of the wear-plate, a portion of the same being broken away for the sake of clearness of illustration.

Referring now more in detail to the several views, it will be seen that the housingv is preferably an integral casting having side walls 1 and 2, end walls 3 and 4, outstanding flanges 0r projections 5 and'6 and a base 7 which is slightly reduced on its upper surface at its opposite sides, as at 8. Extending downwardly and forming a part ofthe base are various ribs 9 so that the housing seen that in the top of the base 7 are formed the two apertures 10 which are beveled; these apertures being located centrally of the sides and in horizontal alignment.

lVith reference now to Fig. 4, there is shown the wear-plate 11 which is preferably formed of hardened steel which is drilled for the reception of two rivets 12, each of which has the conical shaped head 13 on its opposite end. As is well-known, conical headed rivets will be employed and the opposite ends peened so that the opposite heads will be identical in shape.

The angle or taperof the rivet heads corresponds to the bevel of the openings 10 formed in the top of the base 7, the greatest diameter of the opening being slightly greater than the greatest diameter of the rivet head, so that the rivet heads will fit snugly in place when the weai' plate is in position and at the same time be held against any lateral or longitudinal shifting. The size of the plate also is such that it fits snugly within the side walls of the housing, as may be seen from Figs. 1 and 8.

Openings 14: are formed in the side walls of the housing so that a retaining pin may be passed therein and into the roller, as in the other type of Wine side bearings.

It will be understood that when the wear plate and rivet heads wear on their surfaces which are disposed to the roller, the roller will be removed and the wear-plate inverted, thereby presenting a new surface of the wear-plate to the roller and likewise the unused rivet heads.

Furthermore, should both sides of the wear-plate become badly worn, and should both sets of rive-t heads become badly worn, it is a simple matter to remove the roller and insert a new wear-plate with its accompanying rivets and oppositely disposed heads. In this way, the housing may be used for a far greater period of time than would otherwise be the case.

I am aware that it is old to simply pro vide a wear-plate which is reversible in nature, and I do not claim the same broadly as such. but'what I do claim and desire to secure by Letters Patent is 1. A side-bearing housing comprising a base and retaining walls, a wear-plate resting on said base, said wear-plate having a rivet therein, the end of the rivet being formed into a head to correspond with the opposite head, the said base of said housing having an opening formed in its'top for the reception of either head of said rivet, and said Wear-plate with its accompanying rivet to be used first on one side and then on the other, I v v 2. Aside-bearing housing comprising retaining walls for a roller and an integrally formed base, said base provided with an opening in its upper surface, a wear-plate having a rivet rigidly secured thereto and said rivet having its end peened to correspond in shape to the head of the rivet, the opening in the base receiving one head of the rivet, and said wear-plate with its accompanying rivet being reversible to thereby present either surface of the wear-plate and its adjacent head of the rivet to the roller as desired.

3. A side-bearing housing comprising a base and integral side and end walls, the said thereby present the formerly downwardly disposed rivet head and undersurface of the wear-plate to the roller.

4. A side-bearing housing comprising a base and integral upstai'iding retaining wall for a roller, said base provided with two ta-. pered openings in its upper surface, a reversible wear-plate having two aligned rivets extending therethrough and tightly secured to said wear-plate, the opposite ends of the rivets being each similarly headed and one set of heads fitting within the tapered openings in the base when said wear-plate is in position.

5. A side-bearing housing comprising a base and integral upstanding Walls adapted to retain a roller within the housing, the upper portion of said base provided with two tapered openings therein, a reversible wearplate having two aligned. rivets extending therethrough and tightly secured therein, the opposite heads of each rivet being similarly formed, and one set of heads snugly fitting within the tapered openings in the base when said wear-plate is in position, and the width of the wear-plate being such that it tightly fits between the opposite side walls of the housing and thus assisting in preventing any shifting movement .of the wearplate.

6. A side-bearing housing comprising a base and integral upstanding walls adapted to retain a roller within the housing, the upper portion of said base provided with tapered openings therein, a reversible wearplate having aligned rivets tightly secured to said wear-plate and being oppositely headed, one set of heads snugly fitting within the tapered openings in the base when said wear-plate is in one position, the opposite headsadapted to extend into openings formed in the roller and a reversal of the wear-plate thereby reversing the rivet head,

the width of the wear-plate being such that it snugly fits between the opposite side-walls plate and extending upwardly and downof the housing, and the end Walls of the wardly beyond the wearing surfaces of said housing being provided with overhanging Wear-plate, and the base so formed as to reledges. ceive the downwardly projecting portion of 5 7.
