SUPPORT FOR BRAKE HANGERS.

Application filed March 18, 1927. Serial No. 176,394.

My invention relates to supports for pendently securing the hangers of railroad car brakes'to the truck frames, and involves the provision of, suitable socket forming means,

preferably in the form of an extension or arm of such length and thickness as to permit lengthwise slotting for the purpose of producing a hanger link or hanger supporting pin receiving socket; the arm being either integral with or otherwise secured to the truck frame so as topresent the socket preferably in a lateral direction and at a point substantially in alignment with the wheels of the'truck. I

The invention also contemplates suitable means whereby the hanger and the hanger supporting pin will be oscillatably held in the socket; said means involving a structure whereby lateral movement of the link hanger or longitudinal movement of the hanger suportin in is revented'said means bein P e P a constructed to permit an interchange of hangers to be made.

The objects and advantages of my invention'will be readily apparent from the detailed description of thedrawings, where- Figure 1 is a side elevationof my improved arm shown integral with the truck frame (of which a portion is shown partly in section) and provided with my keeper means as employed with a U-shape hanger of which portions are broken away.

As disclosed in the drawings, my improved support contemplates the use of either type of v brake hanger at present in use, namelythe U-shape link as shown at 15 in Figurevl, or

mentary member of said modified form of the continuous link hanger. shown at 16 in Figure 6; thus permitting substitution of the one type for. the other without necessitating change in the'support orkeepery'means.

The exemplification of the invention as disclosed in Figures 1 to 5, comprises an'extension or arm 17, which is prefera'blyshown integral with the top web 18 of a truck frame, although it maybe separatelyformed and suitably bolted or otherwise secured to the truck frame.

The extension 17 consist-s of the flared portion 19 shown'provided'with areenforcing rib 20. The arm which is of comparative width has a side wall 21 extending down- ,wardly and terminating in the horizontally disposed portion 22 formed parallel with the upper flared end 19 of the extension 17; the horizontally disposed portions adjacent to the side wall 21 being also united by means of the end flanges 23. The bottom portion of the extension 17 is'a'lso shown reenforced by means of a web'24; formed integral with the side of the extension or arm'provided with the vertical wall 21; the "web: 24in the particular exemplification being shown formed integral withthe truck frame.

The laterally enlarged horizontally disposed upper and lower portions of the arm are arranged at the outer end of the extension or arm 17 and provide a socket slightly removed from the truck frame,1open at the ends and one side to receive the hangers and the keeper elements later to be described. The upper and lower horizontally disposed portions'are shown provided with aligned. apertures 25 and 26 the aperture 25 in the upper portion being'preferably enlarged and made rectangular or non-circular inconfig uration forthe purposeof receiving the head of the bolt 27,'after the hanger and keeper elements have been placed inthe socket, and turning of the bolt-thus prevented. The keeper means, disclosed in the first five figures of the drawings consists of a pair of 105 complementary plates 'or'members 28 and 29 of suitable thickness to permit the same to be introduced into the socket in the arm as shown v the plates.

in Figures 1 and 3. The two plates are sub stantially identical, except that plateQS is shown chamfered at lengthwise of the in-- termediate portion between the transverse slots 31, 31, while the plate 29 is ln'ovided depth to accommodate the enlarged upper eyleted ends of the U-shaped hanger 15, without necessarily increasing the width oi the entire plates, while at the same time permitting the supporting pin 37, which passes through the eyeleted ends of the hanger 15 to be seated in the longitudinal groove of The supporting pin 37 has its ends resting in the grooves 38 arranged in 7 both ends of both plates in order to provide sufiicient bearing for the pin; the groove 38 being in alignment with the intermediate longitudinal groove 35, as clearly shown. The ends of the plate 28, in alignment with the chamfer 30, are also chamfered as shown 39 to receive the ribs 40 of plate 39. Transverse movement of the plates on each other is thereby prevented.

In order to prevent longitudinal movement of the supporting pin 37, one of the plates, for example plate 28, has its ends provided with the lobes or ears 41, 41 which are adapted to lap the ends of the plate 29 and be disposed across the ends of the grooves 38, as shown in Figure 1. V

The plates or members 28, 29 are shown of length greater than the length of the socket in" the extension orarm of the trnck'trame and therefore extend beyond the socket portion as shown in Figure 1. In order to properly seat the complementary keeper ele ments and firmly hold them in the socket, I have shown both members or plates 28, 29 provided with a right angular boss or shoulder 42 adapted to fit into the closed side of the socket intermediate of the end flanges 23 In practice, the supporting pin 37 is passed through the eyeleted ends of the U-shape hanger 15 and the pin placed into the groove 235 and end grooves 38, with the U-shape hanger straddling the intermediate portion of the keeper element or plate. The top plate is then placed onto the lower plate and the assembled elements then inserted into the socket in the arm, with the angular bosses 42 inserted into the closed side of the socket,

thus bringing the apertures 43, 43 of the two plates into register with the openings 25 and 26 in the arm so that the bolt 27 may be put into place and the nut 44 applied thereto, thereby firmly holding the elements in position but allowing such free oscillatory movement of the hanger as is required in the proper operation of the brakes.

As both plates 28 and 29 are similarly I grooved, it is apparent that either plate may constitute the upper or the lower plate, as in either event the lobes 41 will be disposed across the end of the pin-receiving groove andprevent its longitudinal movement as clearly evident from Figure 1. The chamifersand ribs of the two plates provide a nonsni'iting relation, transversely, between the two plates while the lapping lobes will prevent longitudinal shifting or movement This construction of my improved keeper means has been shown in connection with a i i-shape type of hanger; but it is apparent that a continuous link type of hanger as shown at 16 in Figure 6 may be employed therewith.

With the type of keeper means shown, it

is evident that the supporting pin 37 will have suitable support throughout its length to give it the necessary rigidity for supporting the hanger and brake shoes and that wear resulting from oscillations of the brake hanger will be confined to elements which may be easily replaced as all wear resulting rein. movement of the pin 3?, or oscillations or the continuous type of link. 16, will beconlined to the plates themselves and therefore the integral extensionor arm of the truck frame encounters no wear. The construction, however, is such that assembly of the parts is very easily accomplished. I

In Figures 6 to 10, I show a modified form of the keeper means intended especially for use with the continuous link hanger 16, namely in. situations where no hanger supporting pin isemployed. The keeper and wear receiving means comprises the complementary plates or members 45 and 46 shown in Figures 9 and 10. The keeper members of Figures 9 and 10 are identical with the intermediate portions of keeper members 28 and 29 heretofore described; that is to say, the keeper membcrs45 and 46 consist of the portions of plates 28 and 29 intermediate of the transverse slots 31, 31. Keeper member 45 comprises a fiat block or plate having a transverse groove 47 identical with the groove 35 of the previously described means. The keeper member 45, like keeper 28, is kerfed at 48 to receive the rib 49 of keeper member 46 which likewise consists of a block or plate of dimensions substantially equal to those of block-or plate 4534 Keeper member 46 is also provided with the longitudinal groove 47 the two semi-circular grooves of the two members when the two plates are arranged one above the other as shown in Figure 7 constitute a channel having a diameter sufiicient to receive the end of the continuous link 16 and permit it to have free swinging or oscillatory movement. The two blocks or plates 45, 46', like plates 28and 29, preferably areeach shown provided with the angular surfaces or bosses 42, 42 which terminate short of the ends of the plates in order to fit into the rear end of the socket formed intermediate of the parallelly disposed upper and lower portions of the extension or arm 17. The keeper members 45 and 46 are each provided with registering holes 43 which will register with the holes 25 and 26 formed in the upper and lower portions of the arm for the purpose of receiving the retaining bolt 27, with the head of, the bolt fitting into the non-circular enlarged opening 25 in the top wall of the socket as shown in Figure 7, for the purpose heretofore described, With this construction, like in the previously described construction, all wear resulting from the vibrations and oscillatory movements of the hangers will be confined to the keeper and wear receiving elements 45, 46 and no wear transmitted to an integral portion of the truck frame. It is also apparent that these keeper elements with the hanger may be quickly removed from the socket, to permit renewal when occasion requires; or permit replacement by the keeper members 28, 29 in the event it is desired to substitute the U-shape type of hanger 15 and the supporting pin. I

One side of the enlarged portion of the supporting member or arm,which is off-set from the median line to permit the brake hanger to straddle said portion,is shown with an enlarged non-circular opening 25 to permit the head or enlarged part of the bolt or its nut to come into contact with the adjacent keeper plate and thus effect a firm clamping relation between the two plates. This is of material importance as it is essential to provide means whereby the plates are held in firm seating relation with each other and also firmly clamped to the arm against vibration and chatter.

I have shown the arm preferably formed with a substantially horizontally disposed slot, but it is apparent that the slot may be differently disposed and that modifications in the keeper means may be made, without, however, departing from the spirit of my invention.

What I claim is: V

1. In brake hanger supporting means. a pair of plates arranged face to face with said opposing faces grooved lengthwise to provide a hanger and a hanger supporting pin channel, one of said plates at the ends of the grooves being provided with projecting lips adapted to lap the other plate at the ends of the groove therein.
