Patented June 4, 1935 PATENT OFFICE SAFETY SUPPORT FOR- BRAKE RODS Seth A. Crone, East Orange, N. J., assignor to Buffalo Brake Beam Company, New York, N. Y., a corporation of New York Application August 1, 1934, Serial No. 737,881

3 Claims.

The present invention relates to safety supports for the connecting bottom rods of brake levers for the purpose of supporting the bottom rod in case it should tend to fall upon the track.

5 An object of the present invention is to provide such a safety support which is so constructed that it may be hung upon the brake beam and then positive pressure be given to the support or a sharp blow in order to deflect portions of the 10 safety support whereby to cause the support to be positively bound or rigidly attached to the brake beam. Other objects are to obtain efficient and simple construction.

These being among the objects of the present 15 invention the same consists of certain features of construction and combinations of parts to be hereinafter described and then claimed with reference to the accompanying drawing in which Fig. 1 is a plan of parts of the brake mechanism of a car truck showing the present improvements attached thereto;

Fig. 2 is an elevation of the safety support showing it applied to a beam, the bottom rod being in section;

Fig. 3 is a sectional elevation at right angles to Fig. 2, and

Fig. 4 is a view similar to Fig. 3, except that it shows the support as finally clinched or rigidly attached to the brake beam.

Referring to the drawing, the compression member ID and the tension member ll of the brake beam, which is but partially disc1osed,may be of the usual construction. Mounted upon the brake beam so as to fulcrum thereon are the brake levers l2, l3 which at their lower ends are secured together by the bottom connecting rod 14.

The improved brake beam attachment is preferably formed from a wrought metal bar and constitutes safety means for supporting the bottom rod M in case it tends to fall on-the track. The

safety attachment comprises a stirrup or loop l5 forming the actual rod supporting member and is terminated by two parallel hooks, each comprising an upward leg IS, a cross piece I? and a downward leg I 8 at the outer end of the cross piece, so that each hook stands substantially at right angles to the plane of the stirrup or loop I 5. The legs I B, l 8 are also substantially parallel with each other.

The compression member I 0 of the brake beam may be of the usual channel form so that the flanges thereof lie the one above theother. It will clearly be seen from Figs. 2 and 3 that the safety support or attachment is hung over the compression member so that the cross-connections I! will extend across the top of the compression member. A slight recess I9 is formed at the inner angle between each cross connection I1 and downward leg l8, while another recess 20 is formed on the inner side of the lower end of each 5 free leg 18.

When the safety support is hung in place the recess I9 will be opposite to the upper flange of the compression member, while the recess 20 will be opposite to the lower flange thereof as shown 10 in Fig. 3. To permit ready engagement of the safety support with the compression member, the lower ends of the legs it of the hooks are beveled at their inner sides at 22. So applied the improved safety hanger would be loose upon the beam, but in order to insure its securement to the beam in a rigid manner a sufliciently sharp blow of a hammer directedupon the legs l8 at points between the flanges of the compression member will cause a deflection at 23 of such portions of the legs IS, in some such manner as shown in Fig. 4. The result is that the legs [8 are driven into firm contact with the flanges of the compression member, the upper flange being received in the recesses l9, while the lower flange will be received 25 in the recesses 20. 7

It is apparent herefrom that a very simple construction of safety attachment may be resorted to and it is only necessary to impart sufiicient blows thereto or pressure properly applied, in order to intimately bind and attach the safety attachment to the brake beam so that it will not rattle in service. If the bottom connecting rod [4 should drop it will be supported by the stirrups or loops I 5 of the safety attachments.

What I claim as new is:- 1. In a safety support for brake rods, the combination of a brake-beam channel member, and a bottom rod supporting member having a hook shaped member formed with two connected substantially parallel legs for engaging over the channel member, one leg being free, and the free leg extending downwardly past the two flanges of the channel and forcibly deflected between the flanges whereby to force it against the flanges and rigidly secure it to the channel member.

2. In a safety support for brake rods, the combination of a brake-beam channel member, and

a bottom rod supporting member of wrought metal, having a hook shaped member formed with two connected substantially parallel legs for engaging over the channel member, one leg being free, and the free leg extending downwardly past the two flanges of the channel and forcibly bent between the flanges whereby to force it against the flanges and rigidly secure it to the channel member.

3. In a safety support for brake rods, the combination of a brake-beam channel member, and

5 a bottom rod supporting member having a hook shaped member formed with two connected substantially parallel legs for engaging over the channel member, one leg being free, and having a recess at the inner side of its lower end and there engaging with the lower flange of the compression member, the free leg being forcibly deflected between the flanges to force the recessed end into firm engagement with the lower flange.

SETH A. CRONE.
