C132 BEARING FCT. CLES.

I hereby declare the following to'bc a full,

clear, and exact description or' the invention, such as will enable others skilled in the art to which it appertains io make and use the same. y

Our invention relates to improvements in side bearings for cars and the like, of the type disclosed and broadly claimed in a copending application executed of even date herewith and iled by Franklin L. Barber and Edwin W. Webb and also an application executed by Edwin lV. Webb of even date herewith. l

To the above end, generally stated, the invention consists of the novel devices and combinations of devices hereinafter described and defined in the claims.

In the accompanying drawings which illustrate the invention, like characters indicate like parts throughout the several views.

Referring to the drawingsz.

Figure 1 is a plan View of the improved side bearing;

Fig. 2 is a view partly inside elevation and partly in longitudinal vertical section taken on the line 2-2 of Fig. 1;

Fig. 3 is a horizontal section taken on the line 3-3 of Fig. 2;

Fig. 4 is a transverse vertical section taken on the line 1 -4 of Fig. 2;

Fig. 5 is a detailed view principally in section taken on the line 5 5 of Fig. 2; and

Fig. 6 is a View corresponding to Fig. 2 but illustrates the movable parts of the side bearing moved to one of their extreme positions.

The numerals 7 and 8 indicate, respectively, the body bolster and the truck bolster of a railway car.

The improved side bearing is carried by a body bolster 7, and includes a cast rectangular housing 9, with an open top and bottom. Cast with the upper portion of the housing 9, at the corners thereof, are four horizontally disposed ears 10, having bores l1, through which rivets or other fastening means, not shown, are passed to rigidly secure the side bearings to the body bolster 7.

Epzcmicn cf Letters Patent.

Patented Nov. 12, 1918.

The top surfaces Cf the housing 9 and ears l0, extend in an oblique plane to conform to the surfaces ofthe body bolster to which they are secured and have flat engagement therewith.

On the inner surfaces of the end walls of the housing 9 lare shoulders 12 on which is loosely supported a cover 13, which lits within thc housing 9 and is held thereby, against horizontal movement. The upper surfaces of thc cover 13 extend in the saine oblique plane as thc upper surfaces of the housing 9 and cars 10, so as to bear directly against thc body bolster 7. T he top of the cover 13 is cored for the sake of lightness and the saving of material. The ends of the cover 13 terminate short of the respective ends of the housing 9 and cast therewith, at the bottom thereof, are small anges 14:, provided for a purpose that will presently appear. On the bottom of the cover 13, at the ends thereof, are guides 15 which slidably receive and support a wearing plate 16. When the cover 13 is in position in the housing 9 the wearing plate 16 is held thereby, against removal from the guides' 15.

In each end of the housing 9, is formed a pocket 17 and extending into the housing, at the bottom of each pocket, is a bifurcated bracket 18. On the bottom of the pockets 17 and on the upper faces of the brackets 18 are formed roller seats 19 that have diverging contours which extend from the centers thereof.

A pair of rollers 20 are mounted in the seats 19 and support the ends of a self-centering carrier 21 in the form of a single bar. The ends of the carrier 21 work in the pockets 17 and have on their lower edges, roller seats 22 of the same shape as the roller seats 19 with the exception that they are inverted with respect thereto. A pair of longitudinally spaced fulcrum notches 23 are formed in the upper edge of the carrier 21. Hub-like stops or extensions 24 are formed on the vertical faces of the carrier 21 centrally between the notches 23.

The body bolster 7 is supported from the truck bolster 8 by a pair `of rockers 25, located, the one in advance of the other. These rockers 25 are provided with apertures 26 which extend in the direction of the rocking movement thereof and through which aperture the carrier 2l extends. Fulcrum pins 27 carried by the rockers 25, in the aperbe moved therewith.

tures 26, extend through the fulcrum notches 23 and are normally out of engagement t-herewith. The upperl segmental bearing surface of the rocker 25 supports the wearing plate 16 and the lower segmental bearing surfaces thereof, rest on a bearing plate 28 secured to the truclrbolster 8.-

Normally the rockers 25 rest on the wearing plate 28 and support the car body and load through the wearing plate 16 and cover 13. I/Vhen the load is thus supported the fulcrum pins 27 are entirely out of contact with the fulcrum notches 23 and as long as the load continues on the rockers the movement is simple and said rockers will move back and forth on the wearing plates vand carry with them the carrier 21. V

I/Vhen the car is on a -curve the rockers 25 will be positioned, as shown in Fig. 5, to a greater 0r less degree and as the rockers 25 are interlocked to the carrier 21 by the notches 23 and pins 27, said carrier will This movement of the carrier 21 moves certain of the inclined surfaces of its roller seats 22 onto the rollers 20 and also moves said rollers onto certain of the inclined surfaces of the roller seats' 19. With the rollers 2O thus positioned in the roller seats 19 and 22, the carrier 21 is lifted into a position to bring the fulcrum notches 23 in said carrier into close relation to the fulcrum pins 27.

If the rockers 25 continue to support the load from the wearing plate 28 until the car passes beyond the curve the movable parts of the side bearing will return to normal positions under the action of the holsters with respect to each other, but if the car body lifts with respect to the car truck, the carrier 19 will lift the rockers 25 out of engagement with the wearing plate 28 and said rockers will then swing on the fulcrum pins 27, in the fulcrum notches 23, into perpendicular or normal positions. This swinging movement of the rockers 25 will carry with them the carrier 21, which carrier will at the same time assist in positioning the rockers. The rollers 2O and carrier 21 will at the same time self-center themselves and also assist in positioning the carrier 19. It will thus be seen that the rockers 22 will instantly return to nor,- mal positions and will again be ready to support the load when the car body again assumes a normal position. Extreme movements of the rockers 25 are limited by engagement thereof with the hubs 24 and flanges 29 on the lower inner edges of the ends of the housing 9, (see Fig. 5).

In assembling the improved side bearing the rollers 20 are iirst mounted on the seat 17 and the end portions of the carrier 21 inserted through the apertures in said rockers and the pins 27 interlocked with the notches 23. The assembled rockers and carrier are then placed in the housing with the ends of said carrier resting on the rollers 20. The wearing plate 16 is then secured to the cover 13 and said `cover placed vin the housing and supported on the shoulders 12. To hold the parts in assembled relation before the side bearing :is secured to the body bolster, the upper edges of the end walls of the housing 9 are bent inward as indicated by broken lines at 30 by poundingor -otherwise so that they will overlie the flanges 1&1 on the ends of the cover 13 and thereby hold said cover in position.
