ROLLER SIDE BEARING.

SPECIFICATION forming part of Letters Patent No. 695,849, dated March 18,1902.

Application filed November 8,1901. Serial. No. 81,584. (No model.)

To all whom it may concern:

Be it known that 1, JOHN C. l/VANDS, a citizen of the United States, residing at the city of St.-Louis, State of Missouri, have invented a certain new and useful Improvementin Roller Side Bearings, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a plan view, partly in horizontal section, of my improved roller side bearing. Fig. 2 is a side elevational View, partly in section. Fig. 3 is a vertical cross-sectional view on line 3 3, Fig. 1; and Fig 4 is a side elevational View.

This invention relates to a new and useful improvement in side bearings designed particularly for use in connection with railway rolling-stock. The side bearing shown in the accompanying drawings is of that type known as roller side bearing, and in practice is arranged near the ends of a truck-bolster and on each side of the center plate or bearing, said truck-bolster side bearings cooperating with the side bearings arranged on the bodytransom, which transom forms the support for one end of the car-body.

The objects of this present invention are to simplify the construction of roller side bearings and to provide resilient means whereby the antifriction device is returned to a normal or central position after each operation and independently of the movement of the top side bearing.

My invention consists in the construction, arrangement, and combination of the several parts, all as will hereinafter be described and afterward pointed out in the claims.

In the drawings, 1 indicates what I will designate as the base-plate of myimproved side bearing, said base-plate carrying a track plate 2, which track-plate is preferably made up of hard metal and removable, so as to be renewed when worn.

3 indicates a wall rising from one side, preferably the outer, of the base-plate, said wall having an overhang 4. 5 indicates a spring-housing rising from the opposite or inner side of the base-plate, said housing being formed with a slot 6, preferably, throughout its length, said slot opening inwardly, and said housing also having an overhang7 extending inwardly from the lower edge of its top wall.

8 indicates a frame provided with sockets 9 in one wall and recesses 10 in the opposite wall. ,These sockets and recesses are alined, so as to receive spindles 11, which are journaled therein, said spindles carrying rollers 12. Rollers 12 overlap each other and are staggered and nested, as shown, being preferably loose on their respective spindles, whereby they may rotate independently of each other. A plate 13 is secured to the frame 8 to holdthe spindles in proper position in the recesses 1O.

14 indicates a web or fin extending from the frame 8, one portion of said fin, as indicated at 15, projecting under the overhang 4, and another portion of said fin, as indicated at 16, projecting under the overhang 7.

17 indicates abutments projecting into the spring-housing'at each end of the fin 15. These abutments 17 are designed to operate through the slot 6.

18 indicates spring-followers arranged in the spring-housing,between which is confined a coiled spring 19. A fixed stop or abutment 20 is arranged at one end of the springhousing, and a removable stop or abutment 21 is arranged at the opposite end of the spring-housing, with which abutments or stops are designed to cooperate the springfollowers. The inner walls of the abutments 17 in the normal position of the parts are substantially in the vertical plane of the inner faces of the abutments 20 and 21, as shown in Fig. 2.

In assembling the bearing the track-plate 2 is preferably riveted in position. The frame 8, carrying the antifriction-rollers, is assembled, the rollers being strung on their respective spindles, and the spindles inserted in the sockets 9, which, as shown in Fig. 3, are enlarged at their bottom walls to permit of the tilting of the spindles and the subsequent dropping of the spindles in position in the recesses 10. The plate 13 is nowriveted in position. The antifriction-rollers being assembled in the frame, the frame is now in readiness to be introduced into position, and

to accomplish this the spring 19 is compressed between its followers and the followers inserted between the projections 17. The stop 21 is of course not in position and enables the roller-frame to be inserted at one side of the bearing, so that the spring and its followers will be properly housed. After these parts are in position the stop 21 is secured in place.

It will be observed that the antifriction device is guided insuch manner that it will move on an arc of a circle described from the king-pin of the truck and that the independent rotation of the several rollers will permit of this movement,the rollers rotating according to the arc of their path of movement as determined by the radius of that arc. The liability of these sectional rollers to wear is thus reduced to a minimum and fiat faces are avoided because there is little inducement for frictional contact.

The roller as an entirety can be assembled in the shop in readiness for application. The parts are easily assembled and dismantled, so that repairs and renewals may be quickly made. The base-plate and its integral walls are preferably made of malleable iron, while the track-plate is made of harder metal. The frame may also be made of malleable iron and the rollers of harder metal.

I am aware that many minor changes in the construction, arrangement, and combination of the several parts of my device can be made and substituted for those herein shown and described without in the least departing from the nature and principle of my invention.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is-

1. In a side bearing for cars, the combination with an antifriction device having lateral fins, and curved guideways cooperating with said fins, one of said guideways forming a spring-housing; substantially as described.

2. In a side bearing for cars, the combination with an antifriction device having lateral guiding projections, of a spring-housing in which said projections operate,and a spring in said housing; substantially as described.

3. In a side bearing for cars, the combination with an antifriction device having lateral projections, of a spring-housing forming a guideway with which said projections 00- operate, followers in said housing, and a centering-spring cooperating with said followers; substantially as described.
