RAILWAY TRUCK.

Application filed August 26, 1924. Serial No. 734,197.

To all whom it may concern:

Be it known that I, EINAB G. Hemmer, citizen of the United States, residing at Edwardsville, Illinois have invented a cerlmprovement in Railway Trucks, of which the following is a specification, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to railway rolling stock and consists in an improved truck construction.

My invention is particularly adapted for use in engine trucks of the type which carry the locomotive body through rockers or other supporting elements which must be mounted on the truck below the level of the top thereof in order to lower the point of support.

i The object of my invention is to provide a transom and truck frame construction of light weight yet possessing the strength necessary to take care of the load carried as required by the type of body supports re- In the accompanyin drawings which illustrate a preferred em odiment of my invention, I show a four wheel engine truck having an integral one piece frame, including wheel pieces, pedestals, transoms, and

rocker supporting members, and in these drawings- Figure 1 is a vertical longitudinal section through the center of a truck.

Figure 2 is a vertical transverse section.

on line 2-2 of Figure 1 and is drawn on a r scale.

igure 3 is a vertical transverse section on line 33 of Figure 1 and is drawn onthe same scale as Flgure 2.

The truck is equip ed with the usual wheels 1 and axles 2. t will be understood that the axle journals are provided with journal boxes, not shown, upon which rest the equalizers 3 which carry springs 4 upon which are mounted wheel pieces 5 of the truck frame. a i

Wheel pieces 5 are connected at spaced points by transoms, each of which consists .in a vertically-disposed body wall 7, the top of which is substantially on the level of the top of wheel pieces 5, although an upward projection 8 of-limitedlength may be provided, if desired. The top of the transom is provided with a reinforcing flange 9' extending outwardly and united with wheel pieces 5.

The ends of the transoms are of the same of this shelf between the transoms are connected with the bottom of the wheel pieces by vertical walls 11 and these walls may be reinforced by suitable ribs 12. The depth of these ribs 12 is limited because of the space requirementof the body supporting rockers 13 mounted upon shelf 10.

Due to the space requirements of rockers 13 and the resulting connection between the ends of shelf 10 and the wheel pieces there is a tendency 'for the frame to fail at the junction of the shelf and walls*or of the walls and wheel pieces. To resist this tendency, I rovide transom body walls 7 with. reinforcing flanges 14 located on the outside thereof and extending from points near the center of the transoms upwardly and outwardly to the wheel pieces with which the ends of the flanges 14 are united. Preferably the outer edge of each flange 14 is provided with a reentrant rib 15 which merges with wheel pieces 5 and also mer es with the outer edge of the corresponding ange 9, and ribs 15 may be sha d as indicated at 16 in Figprovided for the locomotive body 17 While I have shown my invention as applied to a four wheel locomotive truck adapted for particular body supporting elements, it is obvious that my invention may be applied to other truck construction with suitable modifications in the details thereof without departing from the spirit thereof as claimed.

I claim:

1. In a railway truck transom, deeper at its center than at its ends, a horizontal load carrying flan e, and an inclined reinforcing flange extending from a point on said transom intermediate the ends of said horizontal flange toward the end of the transom.

2. In a railway truck transom, deeper at its center than at its ends, a horizontal load carrying flange near the bottom of the transom, and inclined flanges extending upwardly and outwardly from a point on said transom intermediate the ends of said horizontal flange.

3. In a railway truck transom, a load carrying flange extending from near the center of said transom disposed independently of the line of strain in the transom roduced b the load, and a reinforcing ange exten ing from near the center of said transom disposed along said line of strain.

4. In a railway truck transom having a. vertically disposed body wall, a load carryin flan e on one side of said wall disposed in open entl of the line of strain in the transom ro uced by the load, and a reinforcing ange on the other side of said wall disposed along said line of strain.

5. In a railway truck transom, a vertically disposed body wall, a horizontal load carrying flange on one side of said wall near the bottom thereof, a horizontal flange on the other side of said wall near the top thereof, inclined flanges on the latter side of said wall extending upwardl and outwardly from near the center of t e transom, and a return rib on the edge of said inclined flange united with said top flange near the ends thereof.

'6. In a railwa truck, an integral frame comprising whee pieces, a transom connecting said wheel pieces and extending below the level of the same, a horizontal flange on one side of said transom and below the level of said wheel pieces, and an inclined flange on the other side of said transom extending inwardly and downwardly from each of said wheel pieces.

7. In a railway truck, an integral frame comprising wheel pieces, a transom connecting said wheel pieces and extending below the level of the same, a horizontal flange on one side of said transom and below the level of said wheel pieces, and an inclined flange 0n the other side of said transom extendin inwardly and downwardly from each of sai wheel pieces and rovided with a reentrant rib paralleling sai transom and united with said wheel pieces.

8. In a railwa truck, an integral frame comprising whee pieces, a transom connecting said wheel pieces and extending below the level of the same, a horizontal flange on one side of said transom and below the level insane of said wheel pieces, and an inclined flange on the other side of said transom extendini inwardly and downwardly from each. ofsaid wheel pieces and provided with a. reentrant rib varying in depth and deepest near said wheel pieces and united therewith.

9. In a railway truck, an integral frame comprising wheel pieces, a. vertically di posed transom connecting said wheel pieces, a load carrying flange on one side of said transom disposed independently of the line of strain in the transom produced by the load, and a reinforcing flange on the oppo site side of said transom disposed along said line of strain.
