ILLINoIs RAILWAY EQUIPMENT COMPANY, A CORIORATION or ILLINoIs BRAKE-HANGER- surron'r Application filed May 16, 1927. Serial No. 191,623.

7 My invention relates to means whereby the hangersof railroad car brakes. are pendently secured to the truck frames so as to permit the necessary oscillatory movement thereof during brake application; the present invention beingmore particularly adapted to the closed link type of hanger.

One object of my invention is to provide a construction whereby a firm non-vibrating lo and non-chattering relation between the hanger supporting or keeper element. and the truck frame is provided to overcome the wear resulting from the use of constructions of this general character. a

The objects of my invention and its advantages will be readily comprehended from the detailed description of the drawing, wherein V Figure 1 is a side elevation of anarm or projection integral with the truck frame (broken away) anda portion of the hanger.

Figure 2 is a vertical sectional view taken on the line 2-2 of Figure 1.. I

Figure 3 is a cross-section taken substantially on the line 3-3 of Figure 2 looking in the direction of the arrows.

Figure 4 is a view substantially. similar to Figure 2, showing a modified form.

Figure 5 is a vertical sectional view sub- 3 stantially similar to Figures 2 and 4, but

showing another modification.

In the particular exemplifications of the invention, the truck frame 10 is shown provided with an arm or extension 11 formed integral therewith and disposed in a direction transversely of the truck. The outer end of the arm 11 is enlarged and provided with a pair of laterally disposed vertically spaced slots which are shown preferably entirely through the rear wall or web of the arm, thereby providing the parallelly, disposed portions 12, 13 and 14 arranged one above the other in spaced relation and connected at opposite sides by the webs 15, 15. The intermediate portion 13 is preferably of slightly shorter length transversely than upper and lower portions 12 and 14, as can be clearly seen in Figure 2. The slots intermediate of the portions are intended to receive a clevis memberor U-shaped strap 16 on the wheel side thereof of such width as to fit comparativelysnugly between the web portions 15, 15 as shown in Figure 3. lVith the clevis or strap of substantial width as shown in Figure 3, the closed end or loop portion thereof will provide the necessary bearing for the link hanger 17; or a hanger supporting pin of a well knowntype of U-shape hanger is employed, the clevis thereof having a width substantially equal to the spacing between the sides of the hanger 17 As shown in Figure 2, the sides of the clevis straddle the intermediate portion 13 and are of thickness corresponding substantially to the distance between the respective portions 12, 13 and 14 so as to fit snugly therebetween. The clevis, which is preferably of a steel forging, adjacent to the closed or loop end thereof, is shown pressed or slightly offset to provide the inner shoulder portions 18 adapted to abut againstthe intermediate portion 13 when the clevis has been completely inserted or forced intoplace. As the vertical dimensions of the loop portion of the keeper means or clevis is such that said loop portion partially enters between the upper and lower arm portions 12 and 14 (which are longer than the intermediate portion 13), I show the clevis provided with the shoulders 18 formed to prevent the too far inward movement of the keeper means or clevis which might cause the hanger 17 being brought'into binding relation with the arm portion 13 and prevent proper free movement of the hanger. The shoulder portions 18, at the same time, provide a partial closure for the inner side of the loop and prevent a sliding movement in the clevis toward and away from the arm of the upper end of the hanger. The shoulders 18, however, are partially rounded to permit free oscillatory movement of the hanger 17 necessary during proper application and release of the brakes. These shoulders 18 preferably extend throughout the entire width of the clevis and provide a wide bearing surface against the slotted portions of the arm 11.

The upper and lower sides of the clevis 16 are each provided. with a slot 19 disposed lengthwise of the clevis and adapted to partially register with slots formed in the portions12,13 and 14 of the truck frame arm or 7 say, the slot 20 in the upper portion 12 'is 'slot 21 in the intermediate ,7 V p p I greater length than slot' 7 made of somewhat greaterlength than the v portion 13, while slot-21is1of slightly 7 g 22 in the lower portion-14. The; slots in the clevis 16 may be slightly longer than the i 1. 50 thQQ ldSnftheke-y, while the forward lon largest slot 20 in the upper port-ion 12."

These slo-ts'are intended-to receiveea lock- 'ing key or wedge member23 'whichis adapted toentendentirely :throughfl the ,upper and lowenportions' 12 and lasjwellas through theintermediate portion 13 and both sides of the ,clevis, 16, Theo-rear side or-longitudinal edge 24 ref the locking key )or wedge member is vertically disposed, I being; perpendicular gitudinal edge is anade sloping in order to taper the keytoward the lower end thereof, 'asdeaflyIshownimFigure-2; V I 1 yA shownq-inzl igure-2, therear vertical edge 2e ofwth'e key member 23 contactswith the inneriends of {the slots 19 in the clevis 16,

while 1 the forward slopinglongitudinal side contacts with :the forwardsloping ends or the slots 20,121 and, 22 :in .the portions v12, 13 'fi-ll d' 14-, respectively, when the wedge memtransverse dimensions of the ,wedge member relativeito ithe slotsi20, 21 and 22 being such that the rear longitudinal side 24 .oifthe WedgeEmem-ber will-not :be in contact with the Iearends oftheslot's 20,21 and 22 while 7 transmitting ,itsiwedging action tothe clevis.

This .permitsgithe, clevis 16. zto be completely forced into place or drawn into the slots until the shoulders -18 of the clevis 1-6 are in abut I tingirelationw-iththejinterinediate portion 13. v in-*F1gurel lshowzamodlfied iorm wheretapereder beveled as shown at-29 to provide a somewhat enlarged opening to receive the loop end ofthe clevis 30. The clevis 30, whichis in general respects similar to clevis :16, except that the loop portion thereof is somewhat larger than the remainder of the clevis; thereby providing 7 the projecting shoulder portions 31 which eXtendbeyond the horizontal planes ofthe upper and lower legs of the clevis. The distance,vertically,

between the shoulder portions 31, is slightly That is to 7 ends of the slots arranged in the ,slots,

. ranged in straddling less than space between the sloping faces 29 of the portions 26 and28, at the'outerends thereof, in order that the head or loop end of the clevis 30,1nay enter between the upper and lower portions 26, 28.

The portions 26, 27and 28 are also each providedJwith a longitudinally disposed slots 20,. 21 and 22, respectively; with the rear alignment, while the iorwardends oi the slots are made sloping downwardly and inwardly and each slot receding orbeeoming shorter toward the bottom pertien28. The legs or two sides of the clevisarealsg longitudinally slotted at 19, like-clevis 16, in'order that the key or wedge member 23inay be inserted through all of rllhefrelation between the rear endsof'theslots 19and the inner. shoulders 18 or the clevis is such that theouter shoulder portions 31- of the headof the clevis will be drawn into wedgingirelation with the tapered or beveled surfaces 29, before the inner shoulders 18 ofthe clevisare in abutting relation with the-intermediate arm portion 27;

awhile the rear vertical edge oi": the key or wedge member23 willbe out ofcontact with the inner ends of the slots :20, 21 and 22, as shown inrFigure 1-. 'AS a result er this con struction the forcingxor wedgingiaction is transmitted to the clevis and cause it to be held firmly, in position. V 1.

The wedge members 23 are preferably made of suitable metal whichpermits the lower-tapered end to be .bentl'latera'lly as shown at 32 after the 'key rmembers have been driven through the slots-to an extentwhere the header" theclevis is drawn l'between the portions12 and 14 in theiconstruction shown in Figure 2, or the shoulder; portions 31 of clevis '80-are drawn :into firm wedging relation with the sloping-faces of the portions 26 and 28 shown in Figured.

In Flglll65, l'sh'ow a modification of the manner in which the clevis is secured or locked in placeso as to prevent all possibility of vibration or chatter; The arm 11 at its enlarged outer end is transversely slotted inithe same manner as heretofore described, to produce the verticallyspaced portions 38, Stand 35; theslots receiving the legs or two sides of the clevis or keeper 1nember 36 arrelation with the intermediate portion 34. The clevis 36 is substantially identical with clevis 16, except that the sides or legs are provided with belt receiving holes instead of slots; the bolt holes of the clevis registering with similar holes in the intermediate portion 34 and the lower portion 35, to receive theibolt 37. The upper portion 33 is provided with alarger and noncircular hole to receive thebolt-head 88, thus not only preventing rotation of the bolt, but placing the head into direct contact with the clevis 86. t f l In practice, the truck side frames and therefore also the projecting arms 11 are usually ofcast metal while the clevis consists of a suitable steel forging possessing more or a less resiliency. It is apparent therefore that g sults in objectionable and serious play. With my constructions large bearing surfaces not only are provided between the elements, but

' the various methods of fastening the clevis in place will securely hold the latter in place; the fastening means being such that adjust ments are possible to take up any possible wear that may result. This is quite essential in brake-mountings or supports where improper wear cannot be permitted because such wear would allow the brake shoes to drop down too far and consequently prevent proper application of the brakes in keeping with the rules and requirements. I

I have shown what are believed to be the best embodiments of the invention which have been described in terms employed merely as terms of descriptionand not asterms of limitation, as structural modifications may be made without, however, departing from the spirit of my invention.
