BRAKE-BEAM SUPPORT.

Application led July 12,

` This invention relates to improvements in brake beam supports, reference being had to the accompanying drawings which illustrate the preferred form of the invention; though it is to'bc understood that the vinvention is not limited to the exact details of construction shown and described, as it is obvious that variousmodiiications thereof within the scope of the claimswill occur to persons skilled in the art.

In said drawings:

Fig. 1 is a fragmentary view of parts of a truck frame 'as seen with the truck end on, the spring plank shown being in longitudinal section as indicated by the line 1-1 in Fig.l 2, and the supports in cross'- section; Fig. 2 is a fragmentary plan View of the spring plank and the supports; 4 Fig. 3 shows a cross-section through the spring plank adjacent one of the supports, taken as indicated by the line 3 3 in Fig. 2, the support being shown partly broken away;

Fig. 4 is a fragmentary sectional view .of the spring plank and a support, similar to Fig. 1 but on a larger scale, illustrating the installation or removal of a support.

My invention relates to brake beam supports and their mounting, and particularly emergency or safety supports (as they are termed), for preventing brake beams which may get loose from falling to the railway track and causing accidents. I aim not only to mount the emergency support in such away that it will be secure when properly fastened, but also to guard against its being carelessly left insecurely fastened. In the form of embodiment here shown and described, my invention is in some aspects in the nature of an improvement of the construction shown and described in U. S. Patent 1,405,429, Feb. 7, 1922, to A. E. Ostrander.

The parts of the truck shown in the drawings include the car wheel 5, the truck bolster 6, the spring plank 7 with one of the bolster columns 8, and the brake lever 9. In the present instance, the spring plank 7 is of channel construction, with horizontal web 10 and upstanding flanges. The safety or emergency brake beam supports 12, 12 carried by the spring plank 7 project to either side thereof with an upward slope, ,in position to sustain the brake beams Qnot 1925.- ser'iai. N.- 121,879.)

with the spring plank web 10,l bycutting or punching a portion thereof free along three, sides and bending ;or yjoggling it outwardl adjacent itsfremainingattachment or root,as shownlat 15in Figs. 1 and 4. In Fig.A =2, two tongues 14, 14 are shown foreach ofthe supports 12, 12.

As Vsho'wn'inthe drawings, each tongue 14 not only engages the 4corresponding support 12, as'above described, but also penetrates it, V,through .an opening lslotted at the base of the `depending angle b ar flange 13..- Byitsfengagement inthe opening 16, -thetongued14 prevents thel support. 12 from shifting in the direction of its own length.

transversely of the spring plank 7. As here shown, each angle bar 12 fa-ces the attached end 15 of each tongue 14 associated with it, so that the tongue penetrates the flange 13 near its own free end.

Disengagement of a support 12 from the corresponding tongues 14, 14, may be prevented by displacing a portion of the plank web 10 laterally, so as to engage the support 12 at one side. As shown in Figs. 1

and 4, the securing means thus employed consists of the free ends of the tongues 1 themselves, which are bent upward (or back) towards the web 10 and into the opening left therein by the initial oii'setting of the tongues, as shown at 17. This is done, of course, after the support 12 has been put in position and pushed home to the roots of the tongues 14, 14 with the latter straight, as shown in full lines in Fig. 4,-the bent position of the free tongue end being shown in dotted lines in Fig. 4.

Not only is such a mode of securing a support 12 against disengagement, by means of a portion of the spring plank web 10, very effective and reliable in itself, but it also Htl support is engaged with the 'tongues 14, 14 and pushed home in the manner indicated in Fig. 4, the entire absence of anythingto prevent its disengagement by a simple re.- verse movement is so obtrusively obvio-us that the workman is not at all likely yto 'nel glect bending the ends of the tongues 14;, 14 laterally, as already described. the boltsecured construction shown in the abovef mentioned Ostrander Patent No, 1,405,429, on the other hand ,-where the tongue of the spring plank web does not penetrate the support at all, but bolts through support, and plank web are relied on to secure the support against disengagement,-it occasionally happens that the nut-s are carelessly left olf the olts, which are then very likely to be jolted out of. the holes'and allow the support to l come disengaged. Such failure to put the nuts on seems to be largely induced by the fact that the mere presence of the bolts in their holes does really,so long as they remain ther e,prevent. disengagement ot'1 the support.

'lVhat is claimed is:

l. The combination of a truck part having a web, a laterally offset tongue attached thereto, and a brake beam support engaged between said part and said tongue, with a portion of the web displaced laterally to secure the support against disengagement.

2. The combination with a truck part and a laterally offset tongue attached thereto, of a brake beam support engaged between said part and said tongue and supported and penetrated lby the latter, with means beyond the portion of the support penetrated by 1,605,452 EST AVALABLE COP\ Seid. tongue. f9.1. preventing disengagement of said support. l
