Specification of Letters Patent. Patanted June 17 1913.

Application filed April 25, 1912. erial No. 623,022.

side bearings for railway cars.

One object of my invention is to provide side bearings strong, simple, eficient and of durable construction.

A further object is to provide side bearings which will permit an increase, over the present railroad practice, of theclearanoe space between the upper and lower bolster bearing plates under excessive oscillation of the bolsters.

A further object is to provide side bearings which in their action will compensate for the wear of the bolster center plates.

A further objectis to provide side bearings having a resilient member capable of absorbing shock and reducing the concussion between the u per due to the tipping oi the bolsters under load, and the oscillations of the car body.

My invention consists in the means that I employ to practically accom lish these objects, as herein shown and escribed, and more particularly pointed out in the claims.

In the accompanying drawings forming a part of this specification Figure 1 is an end view of the upper and lower bolsters of a railroad car provided with side bearings embodying myinvention. Fig. 2 is an ele-' vation of side bearings shown in place be tween the upper and lower'holsters. Fig. 8 is an enlarged end view showing details of both upper and is a ,.hottom plan hr the resilient bearing. Fig. 5 is a plan view of one end of the resilient bearing plate.

In the drawings bolster of a car,

6 represents the body the truck bolster, 8 the lower side bearing base casting secure to the truck bolster, 9 the upper side bearing base casting secuged to the body bolster, 10 an anti-friction roller, 11 a supplemental rocker or cradleinter osed between the antlfriction roller -and t e lower base casting.

and State ings being cylindrical,

My invent-ion relates to improvements in forming bearing plate 20 may he slipped. The

and lower bolsters 20, and at the same lower bearings. Fig. 4

'24 to permit the movement of The lower base casting-.8 is secured to the truck bolster by bolts or rivets 12, which pass through its base flange 13, and is provided with integral flanges or lugs 14 to receive betweenthem the supplemental rocker or adjustable cradle 11.

The anti-friction roller 10 may be of any suitable form-that illustrated in the drawtrunnions 16 at each end. The trunnions and provided with 16 are provided with suitable bearings 17 rigidly secured in adjustable cradle 11.

The upper base castingQ is secured to the body bolster 6 by bolts or rivets 18, 18, which pass-through its base flange 19. The upper base casting is provided with suitable means for securing at either end the resilient bearing plate 20. I prefer to secure the end of the bearing plate 20 by providing thehase casting 9 with the depending flanges 21, 21 the slots 22, 22 into whichithe flanges '21, 21 are preferably notched, as indicated at the points 23, 23, to permit the insertion of the rivets 24, 24, which are passed through the perforations 25, 25 in the base casting 9,.and engage the resilient bearing plate 20 at the notches 26, 26 provided at either end of the bearing plate 20, as shown in Fig. 5.

The spring or bearing'plate 2O furnishes an extended tread face 28 with which the anti-friction roller 10 directly contacts. The bearing plate 20-is made of resilient metal, preferably fiat spring steel of suitable thickness and strength to resist pressure transmitted through the antifriction roller. casting 9 opposite the anti-friction roller 10 is suitably cut away or hollowed out between its ends to furnish a bearing at each end for the spring or resilieiit bearlng time to permit the .fiexing of the spring 20 toward the face 27. I prefer to accomplish this by making the face 27 of the base casting 9 curvedbetween its ends, as shown in Fi 3, thus permitting the spring or resilient aring p ate 20 to rest throughout its length against the face 27 upon its extreme flexing movement.

plate The notches 26 in the plate 20 provide a suit yieldingly The face 27 of the base able loose engagement withthe rivets 24,

the resilient bearing plate 20. Also the bearin plate 20 by reason of its under lo'a tends to curveabout the anti-friction roller, thus enlarging the area of. contact between the anti-friction rollerand bearing plate over the area of contact provided by a bearing plate, which at all times presents a tread surface in a straight plane, and thus also tending to right the car trucks iutheir relation to the car body. 7

-I claim 1. In a side bearing for railway cars, in combination an upper and a lower base castmg, an anti friction roller secured to one of 'face adapted said castings,a flat spring secured to the a curved surface within which the spring may bend. under pressure.

3. In a side bearing for railway cars, the

combination of an upper and a lower base casting with a fiat plate of resilient metal inter osed between the base castings, and an antiriction roller secured to one of said castings, the other base casting bein pro- .vided with seats for either end of the said' spring, and a space between said seats with in. which the said sprin may bend.

4. In a sidebearing ibr railway cars, the combination of-an upper and a lower base casting'with a flat plate of resilient metal interposed between them, and an anti-frictlon roller secured to one of said castings,

the other base casting being provided with seats for either end of the said spring, and a space between said seats within which the said spring may bend, the said spring being held in position by flanges extending over said seats, eachof said flanges being perforated to receive a rivet, and the said spring being notched at either end to engage said rivets.
