BRAKE-HANQER SUPPORT Application filed July 14, 1926. Serial No. 122,302.

Our invention relates to means for supporting the hangers for the brakes of railroad cars in such manner-that the hangers or links are pendently supported in place on the truck side frames. 1 j j Brake hangers are usually supported from an integral portion of the truck side frame which in our construction consists of projec tions or lugs cast integral with the steel side frame. These portions or lugs project from the side frame a sufficient distance and in a direction transversely of the wheelsof the truck; while the hangers or suspending elements are usually in the nature of U-shaped links as illustrated in the drawing or they may be of the loop or continuous link type.

Our invention contemplates a construction which will permit the use of eithertypes of links or hangers so'that the substitution of the one for the other maybe readily made without alteration or'change in the projecting portions or lugs on the side frame or in the keeper or retainerelement employed.

Our invention contemplates means where-' by a three point upward thrust receiving element or member is provided which at the same time acts as a keeper-or'retainer for the hanger or suspending element'and which is of such construction that it may be "inserted into place after the hangers or supporting means have been properly placed on the -projections or lugs of the side'frame and which therefore may be independently removed when occasion requires. Our construction therefore permits assembly of the parts and be readily accom- I hangers 1n order that the hanger may stradsuspension of the braketo plished.

The'objects' and advantages of our inven tion will be readily apparent from the detailed description of-the accompanying drawing, whereina I v Figure 1 s anelevationof a portlon of a truck side .frame and portions of the suspending hanger or link with our improved retainer element or keeper means'shown applied.

Figure 2 is a perspective view, of a porftion of the truck side frame and with its projecting portions or lugs, with parts broken away to show internal construction; the w Figure 3 is a perspective view of the keeper 7 or retainlng element looking at the bottom side thereof.

In the particular exemplification of the invention as disclosed in the drawing, a portion of the truck side frame is shown at 10 provided withthe projection 11 formed integral with the truck side frame and reenforced by the web portion 12. The projection 11 is disposed in a transverse direction relative to the truck side frame and the wheels and the projection is slotted. longitudinally to provide the top and bottom portions or bifurcations 13 and 14 on the wheel side thereof. The bifurcations or portions 13' and 14 at an intermediate point are each shown provided with a corresponding lip 15 arranged parallel in vertical spaced relation as more clearly shown in Figure 2 and each li apertured at 16 to receive a headed pin 1 which is 'inserted after the brake hanger and the keeper element have been put into place.

v The lower port-ion or bifurcation 14 of the projection 11 is longitudinally grooved as shown at-18 in Figure 2 to receive the usual supporting pin shown in dotted lines in F igure 1 at 19 when the hanger is of the U-shape shown at 20 in Figure 1; or to receive one end of the hanger if the latter is of the loop or continuous type frequently employed in this art The lower bifurcationis also slotted transversely as shown at 21,21 at suitable spaced points apart to receive the-legs or sides of the purpose of receiving the lip or projection 25 of the keeper or retainer element 26 shown in Figure 8.

lihe keeper or retainer element 26 is of a thickness corresponding substantially with the vertical spacing between the bifurcations 13 and 1 1- in order that the keeper or retainer element may freely slide into place after the hanger or its supporting pin, as the case may be, has been inserted into position in the groove 18. The keeper *or retainer element 26 comprises a metallic plate which is slotted transversely as shown at 27, 27 at points adapted to correspond with the transverse slots 21, 21, in order to fit over and around the upper ends of the hangers, whether of the 'U- shape or loop type, and permit fnee'osoillatory movement thereof.

.lhe'keeper or retainer element 'as stated is adapted to fit over the pivotally supported upper end of "the hanger and for that reason the keeper 'or retainer plate. along the inner longitudinal"sideis dished on its lower face as shown at 28 to accommodate it to the retaining pin 1'9'or to the upper'endof the loop hanger. The dishing 28 extends lengthwise ofthe keeper plate or retainer elem'ent'26beyond the transverse slots 27,27, terminating a slight distance short of the ends of the keep er platearetainer element so' as to leave the depending lips or projections 29, 29 at both ends. These lips-29amadapted to extend across'th'e end'softhe supporti-ng rod or headless pin-19 and thu's prev'ent longitudinal movement of the latter. As is apparent, these "depending lips 29, 29 will hold the supporting pin 19 against longitudinal movement and thus *obviates the-necessity of pro.- viding any additional means for "locking the pin in place. It'will be understood that the retainer element or keeper plate 26 is therefore of length slightly'greater than the length of the lower projection 14: so thatthed'epending lips 29, 29 will be disposed slightly beyond the sides of the two outer portions or ends of the lower bifurcation 14. j

The keeper plate or retainer element 26 at what may be termed its outer side is shown apertured at 30 which is adapted to register Withthe apertures 16 in the upper'and lower bifurcations13 and 14 to receive-the retainingpin 17. The projection or'li'p 25 ofthe vkeeper plate or element 26, as previously stated, enters the socketor pocket 23 in the wall of the projection 11 and rests on the shoulder or ledge24c'and acts as a centering element which also prevents "lateral oscil la tory movement of the keeper ;'plate or element j l With, our improved structure the keeper plate or element, especially when employed in connection with the U-typehanger, provides a three point'surface adapte'd to receive the upward thrust of the hanger orits suspending pin and thus relieves the upper bifurcation 13 of the integral side frame projection 11 of all wear.

In the application of the brakes, one set of brakes, namely the set on the side of the wheels toward which they are turning, causes a downward pull on the hanger, while the other set of brakes, namely the setof brakes on the rear side relative to the direction in which the wheels are turning, causes an upward thrust on the hanger during each application of the brakes. It has been found in practice that this constant upward thrust causes considerable wear on the supporting lugs or projections of the side frames, in ducing a considerable amount of chatter in the supporting elements, especially after a slight wear has been encountered. This soon results in an increase in wear and undue play to such an extent that proper application of the brakes is affected. As this wear, without our keeper plate, ison an integral part of the side frame where it cannot be renewed or repaired,'it-soon necessitates discarding the side fram'esof the truck before their usefulness otherwise is impaired, thus entailing considenable loss in time and expense.

The exemplification of the invention as disc losed'in'th'e drawing is believed to be the best embodiment of the invention, the description whereof is made in terms G11'113l0 V0(l merely to describe thestructure which may be modified in certain respects without, however, departing, fromthe spirit of our invention.
