Thisinvention relatesto neiv-v and-useful? improvements 1n safety supports for brake` beams.'

The'V object o'f the: present invention is'vtov. provide" a resilient support vfornormally port" adapte'dito 'engage and-ieinforee 'said` resilient'` supporti when* the' latter is placedV supportingf abrakez beamand a rigid sup-j port vmember disposed below' and normally spaced-from thelirst`= member so asnotto' affect' the'l normal "operation thereof i and adaptedv to reinforcetliesam'e and'for-m a rigid support for the'brake beamin'- case ofthe displacement of tlreilatter.

In the form shown in Figure 3, the rigid member 24 is formed channel-shape and both of the vertically disposed flanges are apertured for receiving pins 17.

In the modified form shown in Figures 1 and 5, a bracket 25 is detachably secured to the spring plank by bolt and nut fastening devices 26 and is provided in its upper face With a longitudinally disposed channel for receiving the resilient member 18. The ends of bracket 25 terminate in extenthereivith'; However, When'thebrake-,beam -i sions 27 which extend a suitable distance past the spring plank under the resilient member and have their upper faces curved to correspond to the curved portions 2O of resilient member '18.l Thus, instead of providing a separate member to form the rigid support, said support is formed integral with the bracket. The spacing of the ends of the rigid portions from the resilient member 18 permits free yielding movement of said resilient member within a predetermined range and said rigid members act as safety elements which reinforce the yielding member and which prevent the droping ofthe brake beam to theground in case the latter is displaced. 4

Obviously other changes in the construction and arrangement of parts of my improved brake beam support can be made and substituted for those herein shown and described Without departing from the scope of my invention.

I claim:

l. A safety support for brake beams comprising a resilient track member', and a flanged member for supporting the said track member, .said flanged member being provided with terminal portions normally spaced from said resilient track member and adapted to support and reinforce the same when the latter; is flexed downwardly.

2. A safety support for brake beams comprising a yielding member for yieldingly supporting a brake beam, and a fianged member in fixed supporting relation with the central portion of said yielding member and provided with terminal portions underlying said yielding member and normally spaced therefrom and adapted tol support and reinforce said yielding member when the latter is forced downwardly beyond a certain distance.

3. A safety support for brake beams comprising a yielding member adapted to yieldiingly support a brake beam, and a bracket for supporting the central portion 0f said yielding member and having terminal portions normally spaced from said yielding member and engageable thereby when said member is flexed-downwardly a predetermined distance.

4. In a car construction, the combination nf a car truck part, a bracket carried thereby, a resilient support member carried by said bracket and forming'a yielding support for a brake beam, said bracket being provided With terminal extensions normally spaced from said yielding member and adapted to be engaged thereby and support said brake beam when said yielding member is subjected to excessive weight.

5. A safety support for brake beams comprising a plurality of members, one of said members being resilient and forming# an operative yielding support for a brake beam and the other of said members terminating short of said yielding member and held in fixed relation therewith and provided with downwardly flanged terminal vextensions normally spaced from said yielding member and adapted to reinforce said yielding mem*n ber and form a rigid support for said brake beam.

6. A safety support for brake beams comprising an attaching bracket provided with integral terminal extensions and a resilient supporting member mounted in said bracket and extending under the tension member of said-brake beam toy form a yielding track therefor, the lterminal extensions of VSaid bracket being rigid and extending under said resilient member so as to reinforce the latter and form aI rigid support for ,the compression member when the latter is disv placed. 1 Y

7. In a car construction, the combination with a part of a car truck, of a resilient member carried by said part for yieldingly supporting a brake beam, and a flanged support member supporting said yielding member and havinga terminal 'extension underlying a portion of said resilient memberand adapted to form a rigid support for vsaid brake beam.

8. A safety support for brake beams comprising a yieldingsupportmember for form ing a third or fourth pointi support for brake beams, and a bracket forv carrying said support member and having an extension underlying a portion of said yielding member and normally spaced therefrom, said extension being adapted to catch and support said brake beam in case the latter'is displaced.

In testimony whereof I hereunto affix my signature this 12th day of March, 1925;

FREDERIC T. DE LONG.`
