A box-shaped bolster having a member thereto by rivets 5, thereby forming a subin the form of a rolled member provided with projecting flanges located some distance inwardly from its side edges; substantially as described.

2. A bolster consisting of a plate member, side walls located some distance inwardly from the side edges of said plate member, a rolled member of approximately the same width as the plate member, and projecting flanges on said rolled member which are conple construction and possesses a great degree of strength.

Preferably7 the bottom member 3 is bent upwardly from the central portion of the bolster toward the opposite ends of the bolster and thence extends parallel to the top plate 1, so that the bolster is of greatest depth at its central portion from which point IOO vss

3. A bolster consisting of aplate member, angles connected thereto, a rolled member provided with projecting flanges located some distance inwardly from the side edges thereof, and means for connecting said flanges to the vertical legs of the angles fastened to the plate member; substantially as described.

4. A bolster consisting of a tcp plate, angles connected to the underneath face o'll said plate with their horizontal legs projecting in opposite directions, a rolled member' having upwardly extending flanges located some distance inwardly from the side edges of said member and embracing the vertical legs of the angles .that are secured to the top plate, and fastening devices passing through said flanges and angles; substantially as described.

5. A bolster consisting of a top plate, side walls located some distance inwardly from the side edges of said top plate, a rolled member of approximately the same width as the top plate and provided with flanges which are connected to the side walls of the bolster, and a center bearing connected to said rolled member by fastening devices which pass throughthe same outside of the flanges thereon; substantially as described.

6. A bolster consisting of a top plate, side walls, a bottom plateconsisting of a rolled member provided with upwardly projecting flanges which contact with the top plate at the end portions of the bolster, and means for connecting said rolled member and top plate together; substantially as described.

7. A bolster consisting of a top plate, a bottom plate consisting of a rolled member provided with upwardly projecting flanges, said rolled member being spaced away from the top plate at the center of the bolster and bent upwardly to engage the top plate at the end portions of the bolster, and lillers interposed between said top plate and rolled member at the end portions of the bolster; substantially as described.

8. A bolster consisting of a top plate, angles connected to said top plate to form the side walls of the bolster, a rolled member provided with upw ardly projecting flanges which are secured to the vertical legs of said angles, said member being bent upwardly so that its Vflanges will contact with the top plate at the end portions of the bolster, fillers arranged between said top plate and rolled member cn each side of the flanges on said member, and fastening devices extending through the top plate, fillers and rolled member to connect said parts together; substantially as described.

9. A car bolster in which one of the members is a special rolled beam having flanges arranged perpendicular to the web portion and located some distance inwardly from the side edges of said web portion; substantially as described.
