ILLINOIS RAILWAY EQUIPMENT COMPANY, A oonroRA'rIo v or ILLINOIS BRAKE HANGER Application filed November '6, 1929; Serial No. 405,099.
My invention relates to hangers for the brake shoes of railroad cars 5 the invention having for its object the provision ofhangers adapted to standard truck frame construction' and possessing greater strength than the hangers heretofore employed, while at the same time providing hangers which may be made Without substantial increased cost of manufacture and at the same time being materially strengthened to withstand [the wear and strains to which brake hangers are subjected.
The objects and advantages of myinvention will be readily comprehended from the detailed description of the accompanying drawings, wherein- Figure 1 is a side elevation of a portion of a truck side frame and car-wheel, showing one form of my improved hanger in brakeshoe supporting position.
Figure 2 is a detail view of the hanger in front elevation, with portions of the bracket and brake-shoe lugs shown in section.
Figure 3 is a detail view in elevation of the hanger shown in Figures 1 and 2, as viewed in Figure 1.
Flgure 4 1s a view similar to Figure 2,1llustratlng a modification of the type of hanger shown in the preceding figures.
hanger as viewed at rig t angles to Figure 4. Figure 6 is a top end view of the hangers shown in Figure 2 and in Figure 4.
Figure 7 is a view similar to Figures 2 and 1, illustrating a modified form of hanger.
Figure 8 is a side elevation of the hanger, as viewed at rlght angles to Figure 7.
Figure 9 is a cross sectional view taken substantially on the line 9-9 of Figure 7 as 11) viewed by the arrows.
Figure 5 is an elevational'view of the brake-shoe hangers, inconjunction with suitable meansfor retaining thehangers in place. Aszmy present invention relates to the hangers per se, further detailed description ofthe bracket and keeper element neednot beau entered into. v
In Figures 1 to 3, inclusive, I have shown one form of my invention in the nature of what. is known as the cont nuous or closed .link type having the two elongated parallels sides 18, 18 united at their ends by the integral end portions 19 and 20.- I The sides 18 and the upper end 19 are usually. circular in -cross-secti0n; the" upper end 19 being seated 111 a groove formed mthe lower portlon or lug of'bracket 15 so as to permit the hanger with the brake-shoe to swing toward and awayfrom the truck-wheel.
In order to provide the hanger with a wide bearing surface against the sides 'of I the qg bracket or keeper-elements arranged inthe Jsupport orbracket, Iprovide the upper: end
of the hanger with the integral portions or "lobes 21, '21, which-are made substantially .circular,-as shown in Figures 1 and 3,and err-1.75 tend beyond the normal plane of the hanger; that is to-say, these enlarged portionsor lobes extend laterally beyond the sides 18, 18 andupwardly beyond theupper end 19.
These portions or lobes 21, '21'are made .180
with substantially flat inner faces so as to lap the opposite sides of the bracket 15, as
' shown inFigure 2; the-sides 18, at their upper ends, tapering toward the portions 21, 21
above the upperend 19 to provide reenforcing i 85 ribs22.-'
With my improvement, a very much stronger hanger is providedthan heretofore has been the case, as my hangerisof material- 1v greater strengthat a point where it en- 9o counters the greatest wear, namely at the curved upper end where the strains are encountered. I i T f Inorder to provide a self-locking hanger in its relation with the shoe, I show the lower 05 end 20 oblong .ingcross-section, namely with its opposite vertical sides substantially flat,
as shown inFigure 3. This permits the hanger to-be. inserted into an undercut slot in the shoe headsojthat, when the {shoe and 109 hanger are in normal operative position, dissociation of the hanger and shoe head will be impossible.
In Figures 4 to 6, inclusive, I show a modification of the hanger previously described, in that thelower end 23, like the upper end 19, is also provided with the side enlargements or portions 24, 24, similar to the upper enlargements 21, 21. That is to say, in Figures 4 and 5, I show both ends of the hanger provided with the wide bearing surfaces which are reenforced by the ribs 22 which extend longitudinally of the sides 18 of the hanger and thus greatly reenforce the. wide bearing surfaces which extend beyond the main body portion of the link-or hanger at points where the wear and-strains are encountered.
The lower end23 of the hanger shown in I Figures 4 and 5, like the lower end 20. of the hanger shown in Figures 1 to 3, is also preferably provided with the flat vertical sides for the purpose heretofore mentioned.
The forms of hangers. thus far described are particularly intendedsto be-of the cast metal type, with the. portions receiving the wear and strains materially strengthened and-wide bearing surfaces providedat opposite sides ofthe link.
In Figures 7 to 9, inclusive, I illustrate another modification of my invention as applied to the U-type of link or hanger, which may be a drop forging andtherefore more cheaply made and which consists in converting a U-shape hanger into acontinuous link. I In carrying out this modification of the invention, a forged U-shape link 25 having enlarged apertured ends 26, 26 isemployed; while the lower or closed end 27 is preferably flattened,'as previously described. The inner faces of the enlarged 'apertured ends 26 are countersunk about the-apertures, as
or bushing 29 having a bore substantially the size ofthe'apertures in the enlarged ends 26-for the purposeof receiving the ,pin or rivet 30, see Figures 7 and 9;
With the main part of the hanger a forgnew sleeve to be inserted and employing a new pin or rivet, thus obviating the necesssity of discarding the entire link.
With my invention, brake hangers having wide bearing faces for bearing against the sides of the keeper elements or brackets are provided while at the same time hangers having greater strength than is the case with hangers as heretofore employed and therefore hangers possessing a greater period of 2. A brakehanger composed of an elongated U-shape link provided with enlarged apertured ends, the inner opposing faces of said enlarged ends being countersunk about the apertures, a sleeve disposed between said ends with the sleeve-ends seated in the countersunk portions, and a rivet disposed through said apertured ends and the sleeve.

shown at 28, to receive the ends of a sleeve ing, the arms -or sides of the hanger may be slightly sprung or spread apart to permit the bushing or sleeve 29 to be inserted into the countersunk portions 28 about the apertures. 1
After the bushing or sleeve 29 has been sprung into place, I then insert the pin or rivet member 30 through the apertures of the U-shape link and through the sleeve 29 and upset or, rivet the ends in'place, as shown at 31, thereby firmly holding the sleeve in place :andproviding a continuous link with wide bearingfaces on opposite sides of the bracket in which the hanger is suspended. I
.It is also apparent, that in the'event the sleeve 29 becomes worn, it may be replaced :upon removing the rivet and'spreading the hangersldes apart,'thereby permitting a
