SIDE FRAM AND BRAKE SUPPOR STRUCTURE Claus J. Werner Clasen, Chicago, Ill., assignor to American Steel Foundries, Chicago, Ill., a corporation oi' New Jersey Application July 17, 1947, Serial No. 761,598 6 claims. (ci. 18s-'205) My invention relates to railway car trucks and has particular reference to novel support means for the truck brake rigging. i

The principal 'obj ect of the invention is to provide a bracket which is cast integral with the side frame and which will serve as a support for several parts of the brake mechanism of the truck. v

A further object oi the invention is to design a bracket of the type described possessing the characteristics of light weight, necessary strength and simplicity of design, and economy of manufacture. y

A still further object of the invention is to devise a novel support for a structure carrying a portion of the brake mechanism.

These and other objects of the invention will be apparent from the specification and drawings, wherein:

Figurel is a fragmentary side elevation of a truck structure incorporating my novel invention;

Figure 2 is a horizontal sectional view taken substantially in the plane indicated by line 2-2 of Figure 1 showing the bolster as associated with the side frame; and t Figure 3 is a sectional view taken in the plane substantially as indicated by line 3-3 of Figure 1..

Referring to. the drawings in detail, the inven tion is illustrated in connection with a railway car truck comprising the side frame 2 (Figure 1) havinboard column member wall I8, the web 30 being oiset as at 3i (Figure 2) adjacent the column to afford clearance for the associated inboard bolster lug I4.

At thevupper corner of the web 30 remote from the frame is formed a jawlike structure, generally designated 32, comprising a pair of diagonally aring a compression member 4,`a tension member 5,

and an integral upright column 6 adjacent each end of the frame and merging with said compression and tension members and defining therewith a bolster opening 8 (Figure 1) centrally of the side frame and a window opening I0 adjacent each end of the frame.

A bolster I2 (Figure 2) may have an end disposed in the bolster opening 8, the bolster being spring-supported from the side frame in the usual manner, as will be readily understood by those skilled in the art. The bolster may be provided at each side thereof with inboard and outboard interlocking gibs or lugs I4 and i6 embracing the v adjacent column therebetween.

Each column 6 may be of U section comprising inboard and outboard webs or walls I8 and 20 joined byv an intermediate wall or web 22.

On the inboard side of the frame at the juncture between each column and the compression member is formed an integral bracket 28, (Figures 1 and 3) the bracket comprising a vertically disposed laterally extending substantially rectangular web 30 integrally formed with the inboard side of the compression member and the adjacent ranged vertically spaced substantially parallel webs or

flanges

34, 34 extending from one side of said web 30 in a direction toward the adjacent end of the frame and forming a throat 36 adapted to seat the top chord of a loop hanger (not shown) in the usual manner.

The

flanges

34, 34 are provided with

vertical openings

38, 38 for reception of a pin (not shown) for securing the associated loop hanger, as will be readily understood by those skilled in the art.

The upper flange 34 is connected to the compression member of the side frame by a laterally extending arcuate web 40 merging at opposite ends with the inboard side of the compression member and said upper flange 34. A vertical rib 4i joins the top surface of the upper iiange 34 and the top surface of the web 40. The web 40 also merges at the edge adjacent the bolster opening, with the top edge cf the web 30, thus strengthening the connection between the web 30 and the side frame. To lighten the structure the web 30 may be cored away as at 42 (Figure 3).

On the web 30 beneath said bolster structure 32 is mounted a bracket 44 ailording support for a tubular member, support or crosspiece 46 extending between the side frames of the truck and constituting a basal contact member for engagement with and actuation of a load compensating device forming part of the brake mechanism. The load compensating device is not shown inasmuch as vit forms no rpart of the present invention. Suiiice it to say that the crosspiece 46 serves as an actuating part for said load compensating device.

The bracket 44 comprises a vertical web or mounting plate 48 seated against the web 30 of the bracket 28 beneath said structure 32. At one end of the web 48`is formed a cylindrical housing 50 closed atth'efend adjacent the web 48 by a wall 52, therwall '52 merging with said web 4 8. Within the lhc'iusing are disposed a pair of axially y spaced cylindric'a-lv

resilient bushings

54, 54 such as rubber, said v'bushings being sleeved over the adjacent-fend of the crosspiece 46 and affording a resilient support therefor. It will be noted that the cylindrical housing is formed at its open end with a pair of axially spaced inturned

annular flanges

55, 55, the flanges being spaced from the end of the tubular member 46 whereby said tubular member is afforded universal angling with respect to` the bracket 44 against the compression of the resilient bushings 54.

Horizontally disposed reinforcing

gussets

58, 56 connect the wall 52 of the cylindrical housing 50 with the opposite sides of thev web 48 of the bracket M.l

structure connected to the inboard side of said column and member, a substantially vertical wall beneath said structure connected thereto I'he brackets 28 and 44 are connected to each A other by a plurality of bolts 58. 58 extending through aligned openings in the webs 30 and 48 of the respective bracket.

To reduce the stresses on the bolts, the web 30 ofthe bracket 28 is provided with a horizontal ledge or flange 60 at the bottom edge thereof, said ledge extending laterally from one side of the web 30 beneath the structure 32 and affording a seat as at 62 for the lower,` edge of the web 48 of the bracket 44. At the juncture between the web 30 and the ledge 60, the web 30 may be cored away as at 64 (Figures 2 and 3) to insure a close iit for the web 48 of the bracket 44. For the same purpose the web 48 of the bracket 44 is provided on the surface facing the web 30 with a vertical flange 66 which seats against the vertical edge of the web 30 as at 68. 'I'he ilange 66 on the side opposite that which seats against the web 3D is connected to the adjacent gusset 56.

It is to be understood that I do not Wish to be limited by the exact embodiment of the device shown which is merely by way of illustration and not limitation as various and other forms of the device will, of course, be apparent to those skilled in the art without departing from the spirit of the invention or the scope of the claims.
