T he inventionrelates .to improvements in railway u car-brakcs, and consists in the novel brakefsho'e head hereinafter 'described and 'particularlypointed out.

the claims. The',object 'of the invention is to'providel .a highly escient, (mme and sembrare- Shoe head capable of economical manufacture, and to this end, in the preierred construction, I construct the lead of'fforged metal and in three separatepieces .secured together` and forming between them a. guide-way for the key by `which the shoe maybe connected with said'head..

The brake shoe lrd comprises a forged metal-face plate in one integral p'" The isventionwiu b e fully u pdemtoodrmm the' se."

. forged detainee-plate 15 i'sof substantiels unitransverse middle portion with a' box-loop 2O containing in its upper and lower ends the slots 21 for the key 22, the latter beingvof standard construction: and util'- xzedfor securing `tllebrake-shoe 23 to`th e' head said below the loopA 20 and against-the, Iug24. The slots 21 are preferably notmerelyvertical slots'but extend latertent ofthe key 22 is free between'the wall oi the lug 24 wliichengages-itand-theinner surfaces of tlrejplte 15 which it. engages, 'and the-.keyiis enabled to have a slight yielding action outwardlywith the shoe 23, this being ,due to the.- fact that` a-given portion of the key immediately above and 4b low the lug '24 is free from the surroundingparts.' f

In forming the vertical slots'21''n the face plate 15 for the ey, I do not' remove'ffror'nthe plate-the metal l which occupies the position; 'ofjthe'l slots, but cutthe metal on thxee sides and presstlelips 2 6 thus formed outwardly from the plateso asto create the s lots 2Iv edgesof saidlips'being turnedoutwardlyto engage r andlo'wer edges of said lfiange, as shown in Fig. 1.- The lips 26 and outer end ofthe box-loopZQ flange 27 of th beam and extend transversely the vfull said vlips by-engaging the opposite edgesof the beamilange aid in creating a rigid' structure.

vided with integral box-loops '28, 29, respectively, fonned by slitting Athe metal transversely and pressing the thus partly separated portions outwardly, whereby the loops are fashioned andvertiealopenings or recesses is properly recessed or slotted', as at 30, to pass uponthe form widthj from end to end and is formed at about its 'have a hearing against the face of plate 15 above and A Patented oct. 22', 1907,

f desire to limit myI invention, in everyjinstancalio the 0- outwardly and merge into the upper'flange 18 which -formation of said plate'from forged metal.

downwardly, as at 34, (Fig. 1), wh'ereby a recess is cref4A A ated for the upper edge of the hmm-flange' 27 and said flanges'33 are' enabled to engage the 'outer facel of 'said beamla'nge. Adjacent to their lower end the flanges 33 again turn outwardly 'and thence downwardly to the web of the body-beam 19, thereby forming an eye or loop 35 to receive the usualbcamhanger when it is de sired to suspend the beam from' a point close to said web and in line with the box-loop 20 of the face-plate 15.' After forming the loop 35 thejianges 33 extend engages thebody-bea'm. -Thebox-like part 32 of the upper backsection 16 sustains the flanges 33 and its side walls afford a key-way for the key 22 and-contain aneye 36 to receive the lower end of a brake-beam hanger. The metal in the sides of the bolt-like part 32 is not cut out taform the eye 36 but on the contrary is pressed laterally, es denoted at-37,-Fig. 4, te form a broader bearing' for the hanger than thethickness of 30 sides around' said eye 36,'this increased strengthbeing' said-walls could normally afford and to strengthen. said more d esirable at the upper than at the lower side of said .eye. The section 16'as` whole is particularly.' strong andeflicient and) ispressed from an integral Phew- Th'e'lower back-section 17' also comprisesa vertical cehtralbox-like pat 38 and laterallyextending parts or flanges 39,v which at their lower ends andai: each-side of the vertical center of said section are riveted to the face-plate 15. The flanges39 above their lower end ,portions vextend outwardly from the plate 15 and thence turn upwardly, as at'40, (Fig. 1)', whereby a recess is A created for the lower portion of the beam-flange 27 and -said flanges 39 are enabled to engage# the outer face ofl said beam-flange. Adjacent their; upper end, close to the web of the beam 19, the flanges 39 tum outwardly and extendalong said webrand finally merge into the lower flange 18 which lengages the body-beam.`

The box-like part 38 of the lower section *17 sustains the flanges 39 and its side-walls, at the lower end of the sec'- tion, afford a continuation of the key-way. for the key 22.

When the upper and lower back sections 16, 17 are in l I position there is a space left between their upper and lower end portions to receive the box-loop 20 and lips 2 6, said spare being also sufficient to receive between the said box-loop and lips andthe adjacent portions of Y the flanges 33, 39 facing the sam'e,'the flange 27 ofthe body-beam 19, yvhl'e the `web of said beam is held between the flanges or jaws 18, as shown in Fig. 1, and thereby a ve'ry rigid and durable connection of the brake-shoe head with the .body-beamuis afforded.

The modification shown in Figs. 8, 9 and l0 pertains solely to the formation of the upper back-section 1G.

In the construction shown inFigs, 1, 2 and 3 the sideA walls of the bon-like part 32 are throughout their extent separated from eachotherand the4 eye 36 for the hanger is formed by flanging the metal, as at 37, to pro vide a bearing of considerable extent for the hanger pin. There are instances, however,in which the elon-- gated bearing around theeye 36 would prove to be inconvenient in receiving the lower end of the 'commonly used pot-hook or S-shaped` hanger, 'and to meet this condition I provide the construction shown in Figs. 8, 9 and 10 which differs from the construction shown in Fig, l in that I press together the side walls of the outer portion o th'e box-like'part 32`to form along the outer vertical center portion of the upper back-section- 16 a double wall'41 and in this wall form th'eye 42 for the lower end of the'hanger. It is important that the metal -along the upper portion of the eye 42should afford a 'verystrong bearing and to secure this result I omit in forming lthe eye 42, to completely sever the metal therefor but use a punch having a beveled end s o that `said punch may only sever the metal. along' the line below the 'points numbered 43 in'Fig. 9, and push the metal out from the -hole formed by the punch, thereby. creating a lip along the upper side of th hole which lip I thereafter pressupwardly against the face of the main sheet of metal, therebyv forming a fiange'44'at the upper.

-edge of the eye and at the outerside thereof.` The eye 42is primarily formed by punching two`holesin the plate before the latter is pressed up into the'backQsection 16 and forming at each hole the flange 44 as above described, after which when the, metalfplate is formed into the back-section and the double wall 41 created, the

e aforesaid holes punched in the plate come together to A'constitute the eye 4 2, said eye vat such time having at its upper side and at 'each side of the .double wall 41` the flange 44, the upper edge of the eye then having the strength of four thicknesses of the metal plate, as shown in Fig. 8, and affording not only a suitable bearing for I the lower end of the hanger but avery durable con' struction; The' eye 42 of Fig. corresponds with that part of the invention connected with the eyef36 of Fig. 1

that .the metal of the plate from whichthe upper back.- section 16' is formed is'not cut out, especially at. the upper edge of the holes, to form the hanger-eye but isleft integral with the platej aud'presscd laterallyso as to increase the strength vol the structure about the upper edge of the eye and afford a .suitable hearing for the lower end ofthehanggenv f- I have illustrated the brake-shoe head as applied to a flanged beam 19 which ordinnrilyis of I-shapo but may 'beof any ofthe several shapes used for bmke beams.

The beam 19 is what is commonly called a structural beam-but I desire it to be understipd that the bmkeshoe -head'of my invention is also applicable to tnissbeams. In everyiusirfmce the recess formed between the Vupper and lower'sections to receive thc inner part 'of the body-beam should be informed to the shape of ,to engage the body-beam and aid in affording a proper abutment for the saine. If the flange 27 of the body beam .I9 should, for i|i .-ua|ue, lie in the shape of a, bulb, which is :t common structural shape, the lips A2() linstead said part so as to, along `the portions 34, 4o of the flanges 33, engage the same, and likewise the -lips 26v formed from the face-plate 15 should be pressed iinto a position oi standing vertically would be presse'd lfurther outwardly at their end po tions t-o lap partly around -the bulb.
