RAILWAY VEHICLE STRUCTURE Filed April 18, 1931 4 Sheets-Sheet 4 Patented July 26, 1932 UNITED STATES PATENT OFFICE JOSEPH J. HARLEY, OF GRANITE CITY, AND EDMUND S. BECKETTE, OF .EAST ST. LOUIS, ILLINOIS, ASSIGNORS TO GENERAL STEEL CASTINGS CORPORATION, OF GRANITE CITY, ILLINOIS, CORPORATION OF DELAWARE "RAILWAY VEHICLE STRUCTURE Application filed a in 1s,

The invention relates to railway rolling stockand consists in a novel car body and truck bolster assembly structure.

It is customary to provide means for interlocking the body and truck bolsters to prevent their accidental separation from each other by vertical movement in opposite directions. Usually the interlocking means: is associated with the bolster center pin and takes the form of keys passed through slots in the center pin or is embodied in some more complicated center pin structure.

In electric locomotive construction, it is desirable to eliminate the center pin altogether so that an opening may be formed in the center plate structure to provide a conduit for an air stream leading from a blower on the vehicle body to the electric motors of the truck.

The main object of the present invention is to provide interlocking means between the vehicle body and truck'bolsters, which means will be spaced from the center plate portions or. the center of the bolsters and we accomplish this object by providing interlocking meanson each side ofthe center of the bolsters, such means preferably being in the form of interengaging hook-like devices provided on the body bolster and truck bolster, respectively.

It is a further object of the invention to permit the use of any desired type of side bearing and, with this object in view, we

' space the interlocking device from the side bearings and, preferably, locate tl 3 interlocking device between the side bearings and the center of the bolsters whereby access to the side bearings is facilitated so that inspection and repairs, or lubrication, if desired, may be attended to with minimum difliculty.

These general objects, and other more detailed objects as will appear from the following description, are attained by the structure shown in the accompanying drawings in which Figure 1 is a top view of one longitudinal half of a four wheel truck and a top View of the opposite longitudinal half of a body end member mounted on the truck.

Figure 2 is a side elevation of the truck.

1931. Serial No. 531,164.

Figure 3 is'a vertical transverse section taken on the line 33 of Figure 1.

Figures 1 and 5correspond to Figures 1 and 2, respectively, but illustrate a modified embodiment of the invention.

Figure 6 is a vertical transverse section taken on the line 66 of Figure 4.

Figure 7 is a fragmentary top view of a body and truck bolster assembly embodying another modification of the invention.

Figure 8 is a vertical transverse section taken on the line 88 of Figure 7.

Figure 9 is a detail section taken on the line 9-9 of Figure 8.

The truck shown in Figures 1, 2 and 3 has a frame 1 including a rigid transverse bolster 2 located intermediate the truck axles 3 and provided with a center plate structure 1 having an upwardly facing annular recessed portion 5 surrounding a central opening 6.

The body structure includes sills 7 and a transverse bolster 8 rigid therewith and provided with a depending annular projection 9 adapted to fit in recess 5. The inner side of projection 9 is extended upwardly, as indicated at 10, and forms the Wall of an air conduit leading downwardly from suitable piping (not shown) provided on the vehicle body whereby the cooling air stream is conducted through passages formed by the bolster walls '11 to a discharge opening 12, whence it is delivered to the motor.

A bracket 13 is bolted to the top of the truck bolster 2 and includes a side bearing member 14 and an inwardly extending lip 15 forming, with the remainder of the bracket, a hook-like device facing towards the center of the bolsters.

The body'bolster includes a side bearing member 16 and a hook-like device 17 spaced inwardly therefrom and having an outwardly extendin lip 18. Device 17 faces towards the end of t e bolsters and the lips 15 and 18 are arranged to interlock to limit the movement'of the bolsters away from each other.

Preferably, side bearing members 14 and 16 are provided with renewable wear plates 19. The distance between the opposing surfaces of lips 15 and 18 is greater than the distance between the side bearing elements so that tilting of the bolster will result in wear on the, elements 19 and not on the lips 15 and 118.

By spacing the interlocking elements 15 and 18 inwardly of the bolster from the side bearings proper, it is obviousthatworkmen will have little difficulty inrinspecting; and repairing the side bearings.

Bracket 13 has vertical flanges '20' at'its" ends arrangedtoengage the-ends .of-zthehookr like%-:device-17 so mate-provide an; additional interlocking means and to act as stops for. lime.
