14 Claims.

This invention relates to railway trucks and, more particularly, to means for connecting the lower portions of the side frames at opposite sides of said trucks.

The principal object of my invention, generally considered, is to provide the equivalent of a spring plank for connecting side frames of trucks, breakage at the ends of said spring plank acting member being avoided by articulated or universal connections with said side frames.

Another object of my invention is the provision of means connecting either bolster spring supporting members or the tension member portions beneath bolster or window openings of side frames, with the provision for articulation or universal movement at the points of connection to avoid breakage of said connecting means.

Other objects and advantages of the invention relating to the particular arrangement and construction of the various parts will become apparent as the description proceeds.

Referring to the drawings illustrating my invention, the scope whereof is defined by the appended claims:-

Figure 1 is a fragmentary side elevational view of an end portion of a spring plank acting device or side frame connecting bar, an associated frame, bolster, bolster springs and spring plates being diagrammatically and fragmentarily illustrated.

Figure 2 is a fragmentary plan of the side frame connecting device shown in Figure 1, with portions of the frame and associated springs being diagrammatically illustrated.

Figure 3 is a fragmentary detail plan view of the side frame connecting device, as shown in Figure 2, but on an enlarged scale.

Figure 4 is a transverse sectional view on the line 4-4 of Figure 3, looking in the direction of the arrows.

Figure 5 is a plan view of the side frame connecting bar socket or intermediate member serving for attachment with a side frame or spring 45 supporting plate thereof.

Figure 6 is an end elevational view of the socket shown in Figure 5.

Figure '7 is a side elevational view of the socket member shown in Figure 5.

Figure 8 is a horizontal sectional view of the socket member on the line 88 of Figure 7, looking in the direction of the arrows.

Figure 9 is a fragmentary view corresponding to Figure 1, but showing a modification.

Figure 10 is a fragmentary plan, partly in horizontal section, of the form shown in Figure 9.

Figure 11 is a vertical sectional view on the line I I--ll of Figure 10, looking in the direction of the arrows.

Referring to the drawings in detail, like parts being designated by like reference characters, and first considering the embodiment of my invention illustrated in Figures 1 to 8, inclusive, there is diagrammatically shown a fragment of a truck I comprising a side frame 2 having a tension member 3 and a window opening 4 above said tension member and receiving a bolster 5 and bolster springs 6 disposed between upper and lower spring plates I and 8, respectively. In the present embodiment, the springs are shown as comprising an elliptic orleaf spring 9- and coil or helical springs III.

The frame 2 is, in the present embodiment, of thetype described and claimed in the Barrows Patent No. 1,652,808, dated December 13, 1927, although I do not wish to be limited to this showing. Said frame, therefore, has diagonal reinforcing portions M which cut across the lower corners of the window opening for rigidifying the construction.' Underlying the lower spring plate 8, in the present embodiment, is

what may be termed a springplank end member or spring supporting plate l2 which is desirably upwardly corrugated or embossed, as indicated at I3, to interlock with the diagonal reinforcements Ill on the frame, as will be understood. Other means for interlocking the plate H with the tension member 3 or upper web 14 thereof may be provided, if desired, in accordance with the usual practice.

The spring plank end member if, or what might be termed the truck or side frame connecting bar adapter, has inwardly extending ears i5 spaced longitudinally of the frame 2 and provided with depending apertured lugs i6 receiving a normally horizontal pivot pin H which, in turn, passes through a socket member or casting M for pivotally mounting said member between the ears IS. The socket member l8 has a receptacle or slot M which normally receives the end portion of the side frame tie member 20. Said tie member is desirably pivotally connected to the socket member is by means of a normally upright pivot pin M which intersects the pin H and is received in a corresponding cut-out portion 22 therein, whereby said pin I1 is retained in position without theuse of auxiliary fastening means. The pin it may be prevented from undesired removal or loss by means of a head 23 and a cotter 24 passing through the lower end portion where it projects below the socket casting l8.

Although only one side frame and the adjacent ends of the bolster and spring plank acting device are illustrated, it will be understood that the spring plank acting device desirably connects with a similar side frame in a similar manner at the opposite side of the truck.

Referring now to the embodiment of my invention illustrated in Figures 9, and 11, there is diagrammatically shown a portion of a truck I comprising a side frame 2 having a tension member 3 and a window opening 4* above said tension member. Said window opening, as in the previous embodiment, is adapted to receive a bolster (not shown) and bolster springs B which, in the present embodiment, are shown resting on a lower spring plate 3*. As in the previous embodiment, the springs are shown as comprising an elliptic or leaf spring G and coil or helical springs Ill The truck 2 in the present embodiment, is of the double truss type as described in connection with the first embodiment, although I do not wish to be limited tothis showing. Instead of having a spring plank end member or spring supporting plate, as in the preceding embodiment, the upper Web M of the tension member 3* serves as this plate in addition to its usual function. In order to serve the purpose, said Web W is, in the present embodiment, formed with inwardly extending ears lb spaced longitudinally of the frame 2 and provided with depending apertured lugs .iii which may form continuations of the triangular gussets at the inner side of the frame, said gussets reinforcing the connection between the portions of the web M beyond the upright web portions 255 of the to )ll member and tying said extensions to said upright portions. As in the previous embodiment, tit pending lugs it receive a normally horizonm pivot pin li which, in turn, passes through a. socket member or casting it which may correspond with the member ill of the preceding embodiment, for the purpose of pivotally mounting said member between the ears l5.

The socket member it has a receptacle or slot W, as in the preceding embodiment, which normally receives the end portion of the side frame tie member 20 which may correspond with the member 20 of the preceding embodiment. In the present embodiment, the tie member is pivotally connected to the socket member W by means of a normally upright pivot pin Zi which intersects the pin it and is received ina corresponding cut-out portion 22 therein. The pin 2 i may be headed, as indicated at 23 and prevented from undesired removal or loss by cotter or other retaining means 24.

Although only one side frame and the adjacent ends of the spring plank acting device or tie and associated parts are illustrated, it will be understood that the tie desirably connects with a similar side frame in a similar manner at the opposite side of the truck.

From the foregoing disclosure, it will be seen that I have devised a member for connecting the side frames at opposite sides of trucks, and particularly the spring supporting portions or tension members of said frames. It will also be clear that I have obviated the employment of the rigid,-

or substantially rigid, spring plank which has been employed to connect side frames at opposite sides of railway trucks and which sometimes breaks, particularly adjacent the places of connection with said side frames, and have substituted therefor a tie, as the connecting member or bar, which extends between the side frames and is articulated or universally connected thereto, thereby obviating strains due to relative movement of the frames in longitudinal or transverse planes, and consequent breakage and/or strains due to such movements, while at the same time providing adequate spacing means between the side frames, and particularly the tension members or spring supporting portions thereof.

Although preferred embodiments of my invention have been illustrated, it will be understood that modifications may be made within the spirit and scope of the appended claims.
