UNITED STATES APATENT OFFICE.

TRUCK HOLSTER.

Application filed October l2, 1925. Serial No. 62,049.

This invention relates to improvements in railway car truck bolsters, similar to that shown in Patent No- 1,269,817, granted June 18, 1918, and more particularly to improvements in the end plate construction thereof.

lt is characterized chiefly by providing an end guide and reinforcing means which includes two side and one end member attached together, and each independently attached to the main frame of the bolster.

The ends of the bolster, since they are accessible from the outside of the car, are commonly used for the record and identification marks for the entire bolster, and it is,

therefore, desirable that the piece that bears the marks should remain attached to the bolster when the guide plates are to be renewed so that the record marks will not be lost.

This invention accomplishes the above desired objects. Other objects are to provide for independent removal of either or both of the side plates; to enable the use of more suitable material in the side or wear plates; to facilitate attachment or removal for repairs; and has other objects and advantages which will become apparent in. the following description with reference to the accompanying drawings, in which:

Figure 1 represents a truck bolster having an embodiment of my invention.

Fig. 2 is a plan view of one end of Fig. 1.

Fig. 3 is a side elevation of the end.

Fig. 4 is aplan view of the end guide and reinforcing construction.

ln my end piece construction, I use two substantially rectangular side plates which have vertical guide shoulders formed thereon and which are preferably of a shape suitable for rolling. These plates or guide pieces are riveted to the flanges of the upper truss member and to the side flanges of the end piece which lap over the ends of the guide plates.

rlhe end pieces are cast and provided with pocket which fits over the ends of the bolster frame members, and the bottom of the pocket is extended in a ledge or flange which is riveted to the bolster frame.

Referring in detail to the drawings, the upper truss member 1 is channel-shaped with the marginal flanges 2 thereof extending downwardly. It is bowed up in the center and has the ends 3 upturned so that they lie flat on the ends of the inversely bowed lower truss member 4 which is thickened at the ends so as to provide a shoulder abutting the ends 3 of the web portion of the member 1. A strut 5 extends between the medial portions of the truss members l and 4, which are secured together at the ends by rivets 6.

In my improved end construction, the two substantially rectangular side plates '7, having guide shoulders 8, are riveted at either side to the flange portions 2 of the upper truss member 1, and the bolster end plate 9 comprises a transverse portion 10 having` inwardly extending flanges 11 at the ends thereof, which flanges are riveted to the side plates 7. The end piece 9 is also provided with a pocket or recess 12 which fits over t-he joined ends of the truss members l and 4, and the bottom of the pocket 12 is extended in a projecting ledge or flange 13 which fits under the joined ends` and the end plate 9 is permanently secured to the trussframe independently of the fastening of the side plates by riveting. Preferably the flange 19 is fastened to the end of member 4 by the rivets 13.

The end of the bolster, since it extends through the truck frame, is visible from the outside of the car and accordingly the marks, such as the trade name, serial num ber, date of manufacture, repair record, and other desirable marks, are usually placed on its outer face 14.

1When the guide plates 7 and 7 become worn or damaged from the severe service to which the same are subjected, either or both may be removed by cutting the rivets, and replaced without 'removing the end cap 9 which is now permanently secured to the truss members.

Therefore, the identification of the par-` ticular bolster is not in danger of being lost. Also in this construction, the end reinforcing construction may be easily attached and the wearing parts and 7 may be of a dif ferent material which is more suitable for the requirements than the cast material heretofore used.

Although but one specific .embodiment of this invention has been herein shown and described, it is to be understood that details of the construction shown may be altered or omitted without departing from the spirit of this invention as defined bythe vfollowing claims I claim: 1. In combination in a trussed truck bolllt) ster having a channel-shaped compression member with the marginal flanges extending downwardly, a tension member having its ends secured to the ends of the web et' the compression member, and a' strut between the medial portions of the said members, guide plates riveted te the flanges of the compression member at each end ot' the bolster, and end members riveted to the end of the tension member and to the two adjacent side plates.

Q.' In combination in a trussed truck belster having' a channel-shapes eompressien member with vthe marginal flanges extending downwardly, a tension member having its ends secured to the ends of the web of the compression member, and a strut between the medial portions of the said. mem bers, guide plates riveted to the flanges oit the compression member at e: ch end of the bolster, and end members riveted to the end of the tension member and having` flanges overlying the ends of the adjacent guide plates and riveted thereto.

In combination in a trussed truck bolster having a channel-shaped compression the compression member, and a strut be` tween the medial portions ot the said mem bers, guide plates riveted to the flanges of the compression member at each end of the bolster, and end members having a flange underlying the end vof the tension member and riveted thereto, and having flanges overlapping the adj aeent ends of the guide plates and riveted to the same.

il. In a car truck bolster, guide plates secured to the ends of the bolster' at the sides thereof, and end plates secured to the two adjacent guide plates and also secured te the ends of the bolster independently ot the fastenings for the guide plates.

5.111 combination in a. car bolster, an upper flanged truss member having up! turned ends, a lower truss member having` its ends secured to the upturned ends ot the upper member, a strut between the medial portions lot the upper and lower members, guide plates riveted to the 'flanges ofthe upper member at the ends thereof, and end members having apocket to fit over the ends et the two truss members and riveted thereto and havingl side flanges overlappingl the adjacent` ends of the guide plates and riveted to the same.
