BRAKE-HANGER BRACKET.

n Application filed April 12, 1923. LSerial No. 631,513.

Toall whom it may concern.' i Y Be it known that I, FREDERIC H. BENDER, a citizen of' the United' States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful `Improvements Brackets, `of which thefollowing is a specilication.

This invention relates to brake hanger brackets. I

-In the application of brake hangers to their supports, among other things, 1t 1s essential to consider proper clearance to ac-V commodate -movements of-the brakes when the brake shoe and'wheels are new rand when `worn, and' also to consider the safety with which thebrake hanger is held by its support to prevent falling of the brake mechanism and possible wrecking of a' train, and at lthe same `time consider the rapidity withV which parts maybe -assembled and disas-j sembled; l

`One object vof the invention is to provide simplefnovel andeflicient means for securely supporting brake hangers to meetthe I requlrements above mentioned.`

' Anotherobject is toprovidea simple brake hangerarrangementin `which the parts are interlocked in a manner vwhich insures safety inaddition to "a rapid assembly. and disasf semblyl of the'parts, and Vin, general adapted to meet the various requirements .for successful use under servicey conditions.,

by meansof the arrangement disclosed on the accompanying; sheets f of drawings, 1n

i of the side frame, the brake hanger bracket,

the brake hanger and its keeper.

The Various novel features of the inven- "tion will be apparent from, the following description and drawings and will be particularly pointedout in the appended claims.

Referring generally to all the figures of the drawings, it willbe noted that the invention is disclosed in connection with a side v frame 10 having an integrally formed brake hanger bracket 11, having upper'and'lower jaws 12 'and 13, respectively, which are spaced to provide an'opening 14 which eX- tendsrfrom one side of the bracket vor sup# port rearwardly between vthe jaws. A

.transverse groove or semi-cylindrical slot 15 is provided in thelower jaw 13 forthe reception of the upper :horizontal portionl 16 ofthe brake hanger, which, in this instance, has two downwardly extending arms 1'? which terminate in a 'lower horizontal portion 18- for attachment to a brake head in the usual manner.

f It is apparent 'from all the figures of the f drawings that the upper 'horizontal portion 516 of the brakev hanger is passed through .the openA side of the ysupport betweenthe jawsj12`and 13 and placed in the transverse slot 15. The hanger is then swung inwardly finto ,its limitingposition, as shown by the dot and dash lines at 18 in Figure. L1.y While the hanger is in such position, a keeper for locking `the hanger within the jaws is slid f These and lother objects are accomplished.V

endwise into its locking position, as shown hanger to be dislodged fromits normal sup# portedposition.V It will be noted that the keeper 19 is provided with a tail 20 which is ,curved and conforms generally to the undercurved surface of the lower jaw 13. kThis tail 20, when the hanger is in any of its nor- `mal operating positions, lies between the downwardly extending yarms '17 of the hanger. In other words, the keeper which locks the horizontal portion 16 of the hanger in its support, in turn is locked in its re- The ' Figures o taining position by virtue of the fact that the kee ser tail 2O is locked between the downwardly extending arms 17 of the hanger for preventing endwisc displacement of the keeper. As shown in dot-ted li-nes in and 7, the hanger portion is inwardly beyond the keeper tail 2O to peimit application and withdrawal of the keeper. Said position corresponds to the position shown at 18 in Figuie'el. rllhewdotted line position of the brake hanger, in Figure 4, lis the position or' a hanger when new shoes are in the Abrake `heads and a three-eighth inch'clearance is provided between the brake shoes and the wheel. rllhe position in -full lines in Figure l is the position of the hanger when there is no slice and the brake head is Iber-ringagainstthe wheel.. The vnormal operating position, of course, is intermediate the two last positions mentioned.

ABy means of the arrangement 'hereinabove -described the Vbrake head may "be quickly 4and easily applied to the support and iif'ithdrawn therefrom, the hanger locked iin-position gby the keeper, and the 'keeper in :turn `locked in vposition by the hang-er lso `that in effect it is an interlocking arrangement.

l vIVhena'iigewhanger is applied `tor replac ing an old one, it is conceivable that an unskilled orV careless worker might not replace thekeeper in lits'locking position, in -which event there is'tlie possibility that the brake hanger might be thrown out of its bracket,

resulting .in 'a falling of the brake mechaniemand a possible wreckage of a train.`

To prevent such an occurrence fan additioiidias been ymade to the arrangement shown Iin Figures l, y2 and 3 vand which is shown-in Figures '5, 6 and 7. Ji'igures itwill bejnote'd 'that the upperfjaw In said latter l2 is provided with an apertured ear 2l in which a rivet 22 is secured. Thekeeper is provided with an elongated ear '23 having an. elongated slot 24 therein in which -anA enlarged portion oi''the-lrivet 221is loosely `received. It is apparent, therefore, that Awhile Athe keeper is `tree to slide cndwise `between operative and inoperative positions when-the .hanger *is in fits `innermost position orper- `mitting such movement of the keeper, it is vimpossible accidentally to withdraw the keeper from 'the bracket. 'Accordingly when the bracket hanger is applied to its supporting bracket, the `keeper is always lthere for workmen to set infposition.

It is my fintention to cover all modifications of the invention yfalling within the :spiritand scope of the following claims.

I claim:

l. fIn brake mechanism the combinationof a brake hanger support havingan opening, a brake hanger having` a portion which passes through 'said opening' in algiven-plane .when-the 'former is being applied .to said support, and a keeper in said opening 'for preventing disp'lacement 0I" said hanger by movement of said hanger in the same plane, said keeper in turn being retained in position by said hanger.

2. In brake mechanism, the combination oi a brake hanger support having an open sidel andaigroove, a brake hanger having a portion passing through said open side when rthe 'fiel-mer Lis'fapplied to said support and a-given plane,and aikeeperin said jaws for retaining the hanger in position against "movement in the same plane, saidhanger in turn cooperating to 'retain the keeper in *locking position.

fi. In brake 'inechanisin,"the combination f of a brake hangerV support'having upperand lower jaws,'the lower jaw having a groove ther-ein for the reception of a brake hanger,

a 'brake hanger mountedin fsaidgroove7 and a-keeper having afportion `passing between said jaws and -a groove fitting over a portion vot *the hangerwithin-'saidfjaws forretaining the hanger in position, said keeper Aand vhanger having cooperating-portions whereby the'keeper normally is retained in its lockingv position.

5. In bra-ke mechanism, the combination of Ya brake hang-er supportihaving upper and lowerja'ws afbrake hanger placed between fsaid jawsfby -a movement in one direction,

and a keeper retaining `said vhanger within said vjaws passed into locking relationship --withrespect to'said support and hanger in another direction.

"6. In brake mechanism, the combination Aeta"brakehanger support having upper and ylower jaws, a vbrake 2hangerplaced between saidjaws by a movement in one direction, a keeper retaining said hanger within said jaws passed into locking Vrelationship with respect `rto said-support and hanger in another direction, and -means whereby the Vkeeper can beapplied vonly when the hanger is in a giveniposition.

7. In Fbrake mechanism, they combination of a brake hanger support having spaced jzaws, fafbrakeV hanger received between said .jaws,.andfa keeper havingan interlocked relationship with -said support and hanger -whereby'thehanger is'prevented from accidental displacement, said support rand keeper being movably interconnectedv wherebyftheikeeper iinay be ymoved from one posiA tiontoanotlierbut never disconnected 'from each other.

8. In brake mechanism, the combinationy the keeper may be moved from one position of a brake hanger support having spaced to another but may not be disconnected from jaws, a hanger mounted therein, and a Siidhsupport.` i 10 keeper associated with said jaws.' for retain- Signed at Chicago, Illinois, this 7th day 5 ing the hanger in position yagainst aociden Of April, 1923,
