SIDE BEARING.

Application filed January 22, 1921. Serial in; 429,126.

clear and exact description of the invention,

such as will enable others skilled in the art to which it appertains to make and use the same.

T his invention relates to a roller bearing, and particularly to a side bearing for railway cars, which bearing is adapted to be supported upon and carried by the truck bolster, and the roller thereof adapted to bear upon the wearing surface provided on the body bolster of the car.

It is an object of this invention to provide such a bearing having few parts, which parts can be made of rugged and simple castings and which can be easily assembled. It is another object of the invention to so construct the parts that certain thereof will be sprung into place with relation to the others, and when so positioned, will be normally retained in operative relation.

These and other objects and advantages of the invention will be apparent from the followingdescription made in connection with the accompanying drawings in which like reference characters refer to the same parts throughout the different views, and in which,

Referring to the drawings, the bearing is seen to comprise a frame or housing member 1 which comprises parallel side walls 2 and end walls 3 which are of much less height than the walls 2. The end walls 3 are reinforced at each side by upwardly curved webs i which extend to the lower portion of the side walls 2 which are suitably downwardly curved to meet the same and form a casting of smooth outline and pleasing'ap' pearance. Web members which are, in effect, continuation of the side walls 2, ex-

tend in a straight line downwardly at each side of the end walls 3 outside thereof. The bottom of the housing member 1 comprises a rectangular flange member having the end portions and the side portions 6, which flangesurrounds a rectangular opening in the bottom of the housing member. At the longitudinal center of the flange member 6 are formed inwardly extending lug membore 7 which form a ledge on their upper surface and are beveled outwardly on their undersurface. The side walls 2 of the housing are also provided centrally with outstanding bosses 8, formed on the inside of the housing with channels 9 and the side walls 2 flare outwardly a short distance just above the longitudinal base flange member 6. Securing lugs are formed at each side of the housing member 1, and,.asshown in 1, there are two of these lugs extending in spaced relation on one side of the hearing and one on the opposite face. The lugs are provided with upstanding finishing bosses 10 through which the securing memhere are adapted to pass. The side members 2 of the housing are provided with a slot 2 which extends upwardly at each side from the center of the bearing in substan tial parallelism with the top of the bearing surface of the base member andthe side walls 2 are further provided with cored openings at each side of the longitudinal center to avoid excessive weight.

The base member of the bearing comprises a rectangular plate 11. As shown in Fig. 3, the top surface of this plate comprises two plane surfaces which slope downwardly toward the transverse center of the plate where they are joined by a surface taken on a substantially three inch radius. The ends of the plate 11 are beveled, as-shown in Fig. 3, and the plate is provided with suitable cored spaces on each underside formedbetween the side flanges thereof and a central longitudinal rib. The plate 11, at the sides thereof, and at the longitudinal center, is provided with recesses 12. asshown in Fig. 6, and the flanges 13 which extend along the sides of the plate below the bearing surface are carried over this recess and extend upwardly along the sides of the plate at its'center to the level of the top surface, as shown in Figs. 4 and 6. The lateral surface of the plate, at 1ts central portion, is beveled downwardly and a laterally extending lug is thusformed at this portion, as clearly shown in F1g. 2. The plate is also provided with lugs 15 at the center of the end portions which extend outwardly slightly from the beveled end surface of the plate.

The roller member 16 of the bearing is suitably cored at its center to avoid excessive weight and apertures 17 extend from this cored porion axially of the roller at each side thereof. A locking pin 18 extends through the roller and has collars 19 formed thereon at some distance from each end. The roller member 16 is preferably made of special cast steel. The frame or housing member 2 will be of malleable iron or soft steel and the base member 11 will preferably be made of steel subjected to a suitable heat treatment. In assembling the bearing, the pin 18 will be placed in the roller 16 and the roller and then dropped into the frame member 1 from the bottom thereof. plate members 11 will then be placed in position with th ledge formed by portion l t at one side over the ledge in the housing formed by the lug 7. The plate will then occupy an inclined position in one side inclined downwardly away from the bottom of the housing. The plate will then be swung upwardly and the beveled surface of the portion 1% will contact with the under beveled surface ofthe portion 7 of the housing. The plate will then be forced or sprung into the housing member 1 and the ledge on the side of the plate will spring over the ledge formed by the lug 7 in the housing. When the plate is thus positioned it cannot drop out of the housing and will be prevented fron'i rising therein by the end surfaces th reof engaging the ends of the housing. The end of the pin 18, as shown, will project into the slot 2 f the side members 2 of the housing and the parts will be held in operative relation, as shown in Fig. 2. In the operation of the device the roller 16 will roll on the top surface of plate 11 and the pin 18 will travel in the slot 2, the rib or collars 19 contacting the ends of the apertures 17 and preventing endwise movement of pin 18.

With this construction it will be noted "that the roller member 16 bears only on the plate 11 and is not in any way supported upon the pins 18. The pin 18 merely rests on the bottom of the opening 17 and is loosely carried by said roller. t will also be noted that the ends of the pin 18 do not contact with the edges of the slots 2 in the side walls of the housing. The pin, however, is prevented from moving endwise out of the roller by the collars 19 and the roller is prevented from rising out of the housing The walls by the pin engaging the of the slots 2.

The lugs 15 will prevent undue end play of the plate 11 in the housing. The roller 16 will be returned to central position by gravity, th same rolling down the inclined plate 11 toward the center thereof.

The plate 11 is provided with the extended iorizontal flanges or ledges 13 at the sides thereof. These extend under the walls of the housing to provide an increased bearing surface on the truck bolster in order todistribute the load over a greater surface. Otherwise the load would be too concentrated.

From the above description it is seen that applicant has produced a simple and efficient side bearing. The parts are easily made, rugged in construction, and are so designed that they can be quickly and easily assembled without the use of securing belts or screws, and when once assembled will be retained in operative position.

It will, of course, be understood that various changes may be made in the form and details of the device without departing from the scope of applicants invention, which, generally stated, consists in the mattor shown and described and set forth in the appended claims.
