BRAKE-HANGER sorronn Application filed January 15, 1927. Serial No. 161,415.

My invention pertains to means whereby the brake hangers of railroad cars are pendently supported in place from a portion of the truck frame; the invention having for its object the provision of means adapted to the use of either the continuous link type of hanger or the U shape type of hanger, and therefore permits an interchange of hangers. 7

Another object of my invention is to provide retainer elements for holding the hangcrs in place and of such construction that positioning of the hangers may be easily made and removal when necessary as readily accomplished; the keeper elements being adapted to receive certain of the thrusts encountered by the hangers and therefore taking care of wear resulting from the constant vibration and cillatory movement of the hangers.

Another ob ect of my invention is to provide a construction whereby the hangers or links will be held in proper brake-applying position for temporary use in the event of loss or misplacement of the keeper element while on the right-of-way, without permitting an improper dropping down of the hanger and therefore of the brakes.

My present invention contemplates an arm or extension preferably cast or formed integral with the truck frame and made to provide a pocket or socket to receive either the'link "hanger or a hanger supporting pin and my improved keeper elements; the latter, in conjunction with the pocket or socket forming portions of the arm, being such that lateral or sidewise play of the keeper elements is prevented and also endwise movement of the hangersupporting pin made impossible.

Another object of my invention is to provide a construction whereby rotation of the supporting pin when the U-shapehanger is employed, is made imposslble because of an interlocking relation therewith and as a result all wear, resulting from vibratory and osa Figure 2 is a vertical sectional view taken substantially on the line 22 of Figure 1 looking in the direction of the arrows.

Figure 12 is an elevation of a portion of the arm on the truck frame and of the construction shown in Figure 10; the figure showing. the use of'a continuous link hanger, only a portion whereof is shown. 7

My invention contemplates the use of either the U-shape type of hanger shown at 15 in Figure '1 or, the link hanger shown at 16 in Figure 6; the invention involving means whereby thehanger Wlll be securely held in "place while at the same time permitting the necessary oscillatory movement thereof; Describing the exemphlicationdisclosed in Figures 1 to '5, we find a portionof'the truck side-.fran'ie shown at 17 which, on its inner side and disposed in a direction transversely of the side-frame is provided with an arm 18 preferably integral with the frameand having a top horizontally disposed flange portion 19 which, at predetermined points in the particular ex- These arcuate portions are intended to. provide suitable spacing or clearance therebeneath to receive the enlarged eyeleted ends of the Ul-shape link 15 ,when the latter is employed: The flange portionflg is formed in- I emplii'ication in Fi ure 1, is preferably shown provided with the upwardly disposed arcuate portions 20, 20 arranged coincident with the.

with the arm 18.

flange of comparative width and disposed lattegral with end flange portions 21, 21 which, in turn, are formed integral with the lower end flange portions 22, 22; the lower end flanges 22 being in spaced relation with an intermediate lower flange portion 23 arranged in horizontal alignment therewith. The spacing between the flanges 22, 22 and 23 is'suflicient to provide a socket therebetweeu for the side portions of the hanger 15, or hanger 16 as the case may be, and allow the necessary oscillatory movement thereof. The lower flanges 22, 22 and 23 are shown reenforced by the lips 24: formed integral therewith and That is to say, a continuous erally from the side of the arm 18 is employed, being cut away at bottom for passage of the sides of the hanger, to provide an enclosed pocket open on one side toward the wheels of the truck. 7

The arm 18, at a point intermediate of the arcuate portions 20, 20 and adjacent to the slots or spacings in the pocket for passage of the hanger sides, is provided with the in tegral laterally disposed ribs 25, 25, integral with the top and bottom flange portions or pocket walls 19 and 23. The upper parts of.

' tures to receive a bolt 30 whereby the retainer 40 or keeper element 31, shown in Figure 5, is locked in place; the bolt passing through anaperture 31 in the keeper.

My improved keeper or retainer element,

shown in Figure 5, comprises an elongated plate, of thickness commensurate with: the

vertical width of the pocket on thearm-lS,

with its ends 32, 32 curved or bent towardone side of the longitudinal axis of the plate and therefore arranged parallel with each other. The ends 32, 32 are preferably shown curved at 33 to provide suitable sockets adapted to receive the enlarged upper eyeleted ends of the U-shape hanger 15 when the latter is employed. The plate or keeper element 31, intermediate of its ends 32, is

provided adjacent to its bottom with anjupwardly curved lug or lip 34: formed to pro vide a longitudinal socket 35 for reception of the supporting pin 36 for the U-shape hanger .15 or the upper end of the hanger 16, see

F igure'6. T he keeper element is cut away or recessed at opposite ends of the lip 34 to provide the shoulder portions 37, 37,.see Figure 5, which are adapted to abut against the ribs, 25, see Figure 4. The ends 32 of the 'the supporting pin keeper plate are disposed beyond the sockets between the flange portions 22 and 23 of the lower wall of the pocket, namely at the ends of the main portion of the pocket in the arm 18. These ends 32 of the keeper plate 31 are apertured at 33 in alignment with the longitudinal socket 35 formed by lip 34 to receive 33 of the U-shape hanger 15.

The end walls 21, either one or both, of the pocket, are shown ofl set at 21 in order to provide a small socket at either end, or both ends,of the pocket at a point beyond the ends of the main portion of the pocket where the ends of the keeper plate are 10- cat-ed. The small pocketor pocketsformed by the off-set 21 is for the purpose of receiving the extended ends 36 of thepin 36.

The extension or ends 36 are non-circular in cross-section and are preferably of cross-sectional dimensions less than the diameter of the main portion of the pin That is to say, in the particular exempliflcation a segment of the pin at the ends is cut away to provide a flat side which engages with the shoulder 39 formed by the off-set 21" of the end walls 21 of the pocket; the socket at the end of the pocket being just SUfiflClGfit to receive the reduced end. It is apparent that the pin 36, will, therefore, be held against rotation, with the result that all wear is confined to the replaceable parts of the sup port, namely to the more inexpensive parts, the pin and the link. the reduced portion of the pin is disposed beyond the shearing-point with the result I thatthe structure 1s in no way weakened, but

is fully capable to withstand the strains to which it is subjected. Y r

In application, the pin 36 is inserted through the apertures 38 and through the eyeleted upper end of the hanger 15 and the pin is placed in the socket 35 of the curved lip 34 of the keeper plate. The keeper plate, with the suspended hanger, is then'inserted into the pocket defined by the flange portions 19, 21, 22 and 3; the pin being positioned so that ends 36 will enter the sockets at the ends of the pocket with the flat portions bearing against the shoulders 39.

abut a 'a-inst the ribs 25 while the ii 3 34 will extend into the socket or space intermediate of the Vertical ribs 25, see Figures 2 to 4. The keeper plate is thus properly positioned and also held against any lateral oscillatory movement.- The locking bolt 30 is then inserted through the registering apertures in the pocket defining flange and the keeper- It is also apparent that WVhen the keeper plate has been properly 7 insertedinto place, theshoulders 37, 37 will the upper end of the link is placed in the socket of the lip 34 and wear resulting from oscillations and the downward thrusts will be confined to the link and to the removable keeper element or plate. It is apparent that an interchange of links may be had with my improved structure without, necessitating alterations. In both constructions the keeper plate with the suspended hanger is inserted. edgewise into the open side of the pocket disposed toward the wheels of the truck.

With the ribs 25 extending toward the outer edge of the pocket in the arm 18, it is apparent, that in the event of loss or misplacement of the keeper plate 31, the hanger link or the supporting pin will be held in place against downward movement and dropping of the brakes below proper braking position therefore prevented, as the bolt 30 will maintain the hanger in the pocket or socket and on the ribs 25 until a replacement of the keeper may be made.

In Figures 7 to 12, I show a modification of my invention ,Figures 7 to 9 illustrating the use of the U-shape hanger with its supporting pin, while Figure 12 illustrates'the use of the link hanger. I

In this exemplification of theinvention, a portion of the truck frame is shown at 40 and provided with a transversely disposed extension'or arm 41 of sufficient thickness to permit being slotted longitudinally on one side to provide the elongated pocket or socket open toward the wheels of the truck, intermediate of the top and bottom bifurcations 42, 43. In order to stiffen and reenforce the arm I have shown it provided'with the top rib 44, while the bottom is provided with the web 45 flaring toward and connected with a vertical portion of the truck frame.

At points coincidentwith the sides of the hangers (which are of more or less standard construction), the arm is slotted transversely to a predetermined extent as at 46, 46, to permit the hangers to be pendentlyheld in place and have the necessary oscillatory movement. In the particular exemplification, theseslots 46 are also shown disposed slightly beyond the rib'44 in order to provide clearance for the enlarged eyeleted ends of the U-shape hanger, The socket in the arm is also shown provided with spaced transverse walls or ribs 47 which reenforce the b furcations; the

ribs being cut away to provide supporting pin or hanger receiving grooves and to maintain the same in spaced relation with the bottom bifurcatlon 43 in order that the keeper plate or element 48 may be introduced beneath the pin or hanger as the case maybe. 7

The keeper 48 comprises an elongated. plate of thickness commensurate with the spacing between theupper and lower bifurcations 42, 43, and provided with transverse slots 49, 49 adapted to register with theslots 46 of the arm. One longitudinal side of the plate adformed on the arm; the keeper element 48 and the bifurcations 42, 43 are provided with registering apertures as at 52, 53, to receive a locking pin or bolt 54, which locks the keeper element in place. e The keeper element atoneor both ends is provided with a small rib as at 55, partially closing the en-dsof the pin receiving groove; while'the upper bifurcation 42 on the arm, at least at one end, is provided with a fiatsided lip 56, which is adapted to be in alignment with the rib of the keeper element when the latter is in place; the lip 56 also partially ex tending across the end of the pocket or socket so as toleave a space between lip 56 and the rib 55, as shown in Figures 7 and 8.

T he U-shape hanger supporting pin 57 beyond the shearing point, namely beyond its hearing in the grooved end lug 50 of the keeper element, is provided with a flat-sided extension 58 (see Figure'7) whichis adapt-' ed to fit into the space between the lip 56 and the rib 55 and as a result will hold the pin against rotation. i

\Vith this construction, like in the previously described structure,- all wear will be confined to the pin, and the integral portions of the truck frame or of the arm and the more'expensivekeeper plate will be free of any wear. A seriousobjection to hanger mountings as heretofore employed is therefore entirely eliminated, while at the same time permitting an interchanging of the hangers, themselves, as is apparent from Figure 12, where the link type of hanger 16 is shown substituted for the U- shape hanger 15 and itssupporting pin 57;

the structure in Figure 12being in every other respect similar to that shown in Figure 7.

Itis apparent that the rib 55 and the lip 56, like the shoulder '39. in the construction shown in Figure 1, will hold the pin gainst longitudinal movement also.

hanger 15 is employed. Figure 6 shows the application of a continuous. link hanger'l6 instead of thew-shape hanger 15 and its sup- 'porting pm 36 which; isshown in Figures 1 and 4..
