29 Claims.

This invention relates to railway trucks and, more particularly, to a device adapted to normally underlie an associated brake beam to serve as a support therefor upon failure of the usual supporting means.

The principal object of my invention, generally considered, is to provide a safety device adapted to be movabiy connected to the side frame of a railway vehicle or truck so that it may be positioned to underlie a brake beam to serve as a safety support therefor, or swung out of the way so as not to interfere with the application or removal of said beam.

Another object of my invention is the provision of a safety device adapted to be pivotally mounted between flanges extending from the tension member of an associated side frame so as to extend inwardly therefrom and normally underlie an associated brake beam, or be swung toward said frame out of the way of said beam so as not to interfere with the application or removal thereof.

A further object of my invention is to provide a safety device for brake beams including a bracket involving a web adapted for connection with an associated side frame and anges extending therefrom, and a safety bar pivotally mounted between said flanges for either underlying an associated brake beam or being swung out of the way toward the associated frame.

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 drawing illustrating my in- 1 vention, the scope whereof is defined by the appended claims:-

Figure l is a fragmentary side elevation of the inner portion of a railway vehicle side frame with one embodiment of my invention applied thereto, the associated spring plank and brake beam being shown in section.

Figure 2 is a fragmentary horizontal sectional View showing my brake beam safety bar in operative position in full lines and in inoperative position in skeleton lines.

Figure 3 is a fragmentary-view corresponding to Figure l, but showing a modified form of my invention, with the safety bar removed.

Referring to the drawing in detail, like parts being designated by like reference characters, and rst considering the embodiment of my invention illustrated in Figures l and 2, there is shown a portion of a railway vehicle or truck side frame l comprising a tension member 2 and bolster guide columns 3, only one of which is illustrated, up-

(Ci. 18S-210) standing therefrom for spacing intermediate portions thereof from the compression member (not shown). The tension member 2 may comprise flange or shelf portions l extending inwardly from the inner face of the inner Wall, web or flange 5 of said tension member, and serving to extend the spring plank or spring seating area 6 of the frame on which rests the spring plank 'i'.

Portions 5 and alone or in combination with spring plank 'l comprise the usual spring seat structure.

In the present embodiment of my invention, the flange is extended to provide an auxiliary shelf portion beneath the guide columns 3, from whence it is diverted upwardly, as indicated at 8, to taper or provide generally triangular reinforcing gusset portions, disposed at an angle to the flange i and which finally merge into the diagonal end portions Q of the tension member. Underlying the ange portions 1i and 8, and spaced therefrom, are angular flange portions lil forming, with the flange portions i and 8, a pocket i i receiving the foot of a safety bar I2. The flanges :l and lil, and the foot of the safety bar l2, are, in the present embodiment, apertured, as indicated at i3, i4, and l5, to normally receive and form bearings for a pivot pin lil, by means of which the bar i2 is pivoted to the frame i so that it normally underlies the associated brake beam l? to serve as a support therefor in case the usual supporting beam means i8 should fail, while at the same time it is adapted to be swung toward the frame i, as indicated in skeleton lines in Figure 2, so as not to interfere with the application or removal of said beam.

The safety bar, in the present embodiment, comprises portions thereof angularly disposed with respect to one another, so that the foot portion i 9 may lie generally parallel to the frame I when in normal position, while the body portion 2@ extends inwardly and diagonally, terminating in a head portion 2i which provides an upper, preferably iiat, surface 22 normally underlying the associated brake beam Il and in close proximity thereto, so that if the beam should accidentally be torn from its normal fastenings, it will not drop on the track, but will instead be supported on the safety bar I 2 and a corresponding supporting device on the other frame, it being understood that although only a portion of one of these truck side frames is illustrated, yet each side frame desirably has two safety bars pivotally mounted thereon so that each of the two brake beams has a bar underlying each end thereof. In order to prevent the bar l2 from unintentional deiiection from normal or operative position, the same is desirably held in position, as by a securing device or cotter 23, which may extend through normally registering apertures 2li and 25 in the foot portion lg of the bar and the flange lil of the side frame therebeneath. Undesired removal of the pivot pin i6 may be prevent-ed in any desired manner, but, in the present embodiment, in which the axis thereof is diagonal, so that the bar l2 may be swung diagonally upward to lie along the diagonal end portion 9 of the tension member Ki2, it will be seen that no separate securing means is necessary as the spring plank l lies, above the head of, and on the axis of the pin when assembled, and prevents loss or undesired removal thereof.

In the present embodiment, the safety bar l2 is formed as a casting, with a generally upright web 26 extending substantially the full length thereof, the parts of said web comprising the foot I9 and the head 2l, however, being angularly disposed with respect to the intermediate portion thereof, as shown most clearly in Figure 2. The intermediate or body portion 20 of the safety bar or casting l2 is generally Z-shape in section, that is, the upper and lower flanges 27 and 28 extend in opposite directions, the upper ange 2 merging into the angularly disposed foot portion of the web 26, and the web portion provided with the brake beam supporting surface 22 at the other end. The lower flange 28 merges into the deflected portion of the web 26 in the head of the casting and is extended beneath the web portion 26 at the foot end to form the flange portion 29 which receives the retaining cotter 23. The web 26 is expanded at the junction between the body and foot portions thereof to form the apertured spool Sii which receives the pivot member i6. It will, however, be understood that the bar, if desired, may be of a form different from what is here specifically described.

Referring now to the embodiment of my invention illustrated in Figure 3, a construction is there disclosed which is identical with the previous embodiment, except that the flanges ia and Illa, instead of being integral with the frame or tension member 2@L thereof, are formed as part of a bracket or casting 3l, the web 32 of which, from which the flanges da and lila extend, being connected to the tension member 2EL of the associated frame la in any desired manner, as by means of rivets 33. In this way, my safety bar may be employed with frames of conventional construction by merely connecting a bracket member thereto and then pivoting the safety bar to said member.

From the foregoing disclosure, taken in connection with the accompanying drawing, it will be seen that I have devised a safety bar secured in place by means intersecting said bar and an asso.- ciated frame, or'flanges extending therefrom, or from a member secured thereto, adapted to either underlie one end of a brake beam for catching said beam in case the usual supporting means should fail, or be swung out of' operative position to avoid interference with the application or removal of the beam, means being provided for securely holding the bar in operative position, and said bar being adapted for use either with a frame especially designed for the pivotal mounting thereof, or with a conventional frame to which a supporting bracket member is secured.

Although preferred embodiments of my invention have been illustrated, it Vwill be understood that modifications may be made within the spirit and scope of the appended claims, and although the beam I1 is shown with a plate 34 riveted thereto and overlying the supporting surface 22 of the bar l2, I do not wish to be limited toy this showing.
