27 Claims.

My invention relates to railway rolling stock and consists in an improved truck frame and brake beam mounting structure.

A comparatively recent development in cars 6 has been the use of trucks without any bottom tie or spring planks, which parts have hitherto been used for mounting brake beam guides, safety guard, and third or fourth point supports. In the absence of the spring plank or corresponding member, some other manner of carrying the parts mentioned for cooperating with the brake beam is desired, and hitherto no successful apparatus has been provided so far as I am aware.

The object of my invention is to provide means on the side frame for carrying a suitable brake beam guide, safety guard, or support.

In the accompanying drawings which illustrate my invention,

Figure 1 is in part a side elevation and in part a vertical longitudinal section through a six wheel car truck embodying my invention.

Figure 2 is a top view of one longitudinal half of the same truck.

Figure 3 is a vertical transverse section through the side frame taken substantially on line 3-3 of Figurel. I

Figure 4 is a section similar to Figure 3 but illustrating a modified form of my invention in which the arm for supporting the brake beam elements is made separately and applied to the side frame.

Figure 5 is a top view of the arm shown in Figure 4.

Figure 6 is an end view of the same.

Figure 7 illustrates another modification of my invention.

In the truck shown in Figures 1, 2and 3, the usual axles and wheels are indicated at 1 and 2, respectively, and it will be understood that the axles are provided with journal boxes upon which the equalizing truck side frame elements 3 and 4 are mounted. The features of these elements aside from those illustrated form no part of my invention.

The side frames are provided with suitable recesses 5 and seats 6 for receiving and mounting -the bolster supporting springs 7. Above and inside of each spring seat 6 is a bracket 8 to which the brake hanger may be pivoted in the usual manner.

Below the brake hanger bracket and extending inwardly from the side frame is an arm 9 which is adapted to extend under the level of the brake beams which are here shown as being of the truss type, each having a compression member 10 and a tension member 11. On the inner end of arm 9 are transversely and downwardly extending elements which form a bracket 12 adapted to carry a member 13 which extends longitudinally of the truck and forms a fourth 60 point support or guide for the brake beams.

This means may also serve as a safety guard to prevent movement of the brake beam downwardly of the truck.

In Figures 1 and 2, I show the brake beams as 5 being equipped with fourth point supports 14 resting upon member 13.

In the preferred embodiment of my invention illustrated in Figures 1, 2 and 3, the side frame, spring seat, brake hanger bracket, and brake beam support arm are formed integrally, and it is believed that such embodiment of my invention is the most economical and will possess adequate strength with the minimum amount of ma- I terial and also will eliminate the expense of assembling separate parts and the necessity of inspecting and maintaining a separate part structure.

My invention may be embodied in separa parts, however, and in Figures 4, 5 and 6 I illustrate a support arm 15 which is formed independently of the side frame, spring seat, and brake hanger bracket and is adapted to be attached to a longitudinal web of the truck side frame 16 by rivets 1'7 spaced transversely of the web. The

inner end of the arm is provided with integral bracket elements 18 corresponding to those provided on the structure-shown in Figures 1, 2 and this form of my invention, the hanger bracket is indicated at 19, but it will be understood that this may be used or not and forms no part of the support arm 15.

In the modification illustrated in Figure '7 the hanger and bracket 20 and the brake beam support arm 21 are formed integrally with each other but separatley from the side frame 22 and the laterally projecting flange 23 on the brake bracket and support arm casting is secured to a horizontal web of the side frame by rivets 24 spaced transversely of the web ,and may form the seat for the bolster springs. In this structure, I have shown a boss 25 on the lower side of flange 23 9 and have pmvided a corresponding recess 26 in the side frame to receive the boss and assist the rivets 24 in retaining the bracket arm casting in position.

In each of the last two forms described, the

plate the exclusive use of all such variations as come within the scope of my claims.

I claim:

1. A car truck side frame having an arm sup ported exclusively thereby and extending inwardly therefrom for carrying a brake beam engaging element below the brake beam.
