SIDE BEARING FOR RAILWAY CARS.

Application filed October 3, 1927, Serial No. 223,717. Renewed February 28, 1929.

My invention relates to side bearings for railway cars.

An important object of the invention is to provide a side bearing of the above mentioned character, which may be readily adjust-ed to different elevations, and which is self-locking for the adjusted positions.

A further object of the invention is to provide a side bearing of the above mentioned character which is simple in construction, strong and durable.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawings, forming a part of this specification, and in which like numerals are employed to designate like parts throughout the same,

Figure 1 is an end elevation of a railway car truck, showing my side bearings applied thereto,

Figure 2 is a plan view of the same,

Figure 3 is a plan view of the side bearing embodying my invention,

Figure 4 is a side elevation of the same,

Figure 5 is a longitudinal section taken on line 5-5 of Figure 3,

Figure 6 is a transverse section taken on line 6-6 of Figure 3, and,

Figure 7 is a perspective View of one of the adjustable wedges.

In the drawings, wherein for the purpose of illustration, is shown a preferred embodiment of my invention, the numeral 10 designates a railway car bolster, arranged above the usual truck bolster 11, and pivoted thereto at 12, by the means embodying the usual king-pin. Arranged upon opposite sides of the pivot 12 are my side bearipgs 13.

Each side bearing 13 embodies a preferably rectangular casing or box 14:, having its longitudinal axis extending transversely of the truck bolster 11. This box is provided upon its opposite sides and adjacent to its bottom with any suitable number of ears 15, preferably formed integral therewith, which ears are bolted to the bolster 11, as shown at 16. Arranged within the casing or box 1 1 and extending longitudlnally thereof in parallel relation to the sides of the same, are partitions or walls 17, preferably integral with the casing or box.

- These partitions are vertically arranged and are provided with vertical slots 18, extending through the tops of the same. Mounted within the casing 14 between the partitions 17 and the side walls 19 of the casing or box, are stationary wedges 20, having their upper faces inclined, and provided with teeth or ratchet teeth 21, which are inclined toward the upper ends of the wedges. While the wedges 20 are shown as made separate from the casing or box 14, they may, of course, be formed integral therewith.

Arranged upon the stationary wedges 20 are adjustable wedges 22, the tops of which are horizontal and the bottoms of which are inclined, corresponding to the inclination of the tops of the stationary wedges 20. The inclined bottoms of the wedges 22 are provided with teeth or ratchet teeth 23, inclined downwardly, to interfit with the teeth 21, as shown. The adjustable wedges 22 are equipped with pins 24, rigidly attached thereto and these pins project outwardly be yond the box 14 through longitudinal slots 25, formed in the sides 19. The purpose of these pins is to provide means for lifting the wedges 22 and effecting their longitudinal movement.

The numeral 26 designates a roller, mounted upon a shaft 27, which is horizontally ar ranged within the vertical slots 18, and rest upon the horizontal tops of the adjustable wedges 22.

In operation, the car bolster 10 has its outer portions adapted to engage or rest upon the rollers 26. When it is desired to vertically adjust the roller 26 to elevate it, the wedges 22 are shifted longitudinally toward the upper end of the stationary wedges 20. The teeth 23 of the adjustable wedge 22 will trip over the teeth 21, and when the adjustable wedge becomes stationary, these teeth will automatically interlock, and hence the adjustable wedge is locked at the adjusted elevation. The wedge 22 is, therefore, self-locking, without the aid of pins or the like, and there are no parts to work loose which would permit of the improper lowering of the wedge 22.

It is to be understood that the form of my invention, herewith shown and described, is

to be taken as a preferred example of the same, and that various changes may be made in the shape, size and arrangement of parts, without departing from the spirit of my invention, or the scope of the subjoined claims.

Having thus described my invention, I claim:

1. A side bearing to be arranged between a car bolster and truck bolster upon one side of the pivot connecting such bolsters, comprising a pair of stationary Wedges arranged in spaced relation and having upper inclined faces provided with teeth, adjustable wedges having lower inclined faces provided with teeth and mounted upon the stationary wedges, the adjustable wedges being adapted to be shifted longitudinally of the stationary wedges and the co-acting teeth serving to lock said wedges together, a roller arranged between the pairs of wedges, and a shaft carrying the roller and mounted upon the adjustable wedges.

2-. A side: bearing to be arranged between a car bolster and truck bolster upon one side of thefpivot connecting such bolsters, coniadjustable wedges being adapted to be shifted longitudinally of the stationary wedges and .the co-acting teeth serving to lock the wedges together, stationary members having substantially vertical openings, a roller arranged between the wedges, and a shaft carrying the roller and mounted Within said openings and supported by the adjustable wedges.

In testimony whereof I affix my signature.
