Patented May 3, 1932 UNITED STATES PATENTIOFFICE JOHN A PILCI-IER, F ROANOKE, VIRGINIA, AND WILLIAM E. WINE, 0F TOLEDO, OHIO RAILWAY CAR I Application filed March 24, 1928. Serial No. 264,466.

Our invention relates to railway cars and more particularly to improvements in the construction and arrangement of the body bolster and associated parts.

A principal object of the invention is to produce a body bolster of simple and rugged construction especially suitable for application to drop bottom railway cars having an inclined floor.

A further object of the invention consists in forming the interior of a drop bottom railway car, having a longitudinally inclined floor portion and employing inside side stakes, with means whereby the flow of granular lading or the like downthe inclined floor portion is uninterrupted by the side stakes.

A primary feature of the invention consists in providing a railway car with a body 2 bolster formed of a plurality of sections respectively secured to opposite sides of the car center sill, each of said sections being formed with an upstanding plate-like extension interposed between the top of the center sill and the car floor affording a sup- I port for the latter, the bolster extensions being rigidly connected.

it further feature of the invention resides in constructing a drop bottom railway car involving a car body having a floor and'sides, with side stakes overlapping the inner faces of the car sides and a body bolster having its ends projecting outwardly beyond the inner edges of adjacent side stakes, the car body having upon its interior transversely inclined portions extending downwardly away fromv the car sides in 'alinement with the stakes longitudinally of the car.

Another feature of the invention consists in forming the car body of a drop bottom railway car with a floor sheet and a side sheet, and in combining therewith a body bolster disposed below the floor sheet and .a side stake rigidly secured to the bolster adjacent one of its ends and projecting upwardly therefrom inside of the car body, the

bolster being provided adjacent the side stake with an upstanding projection, the upper face of which is inclined transversely of the car and extends downwardly toward the longitudinal axis thereof, one of said sheets being fashioned with a correspondingly inclined portion to overlappingly engage the upper surface of the bolster projection.

A still further feature of the invention resides in constructing a body bolster, adapted to be disposed below the fioor of a railway car and connected to the center sill thereof, with portions projecting upwardly beyond the car floor adjacent the opposite ends of the bolster, said portions being respectively arranged in overlapping engagement with portions of the car sides.

Other and more specific features and advantageous constructions and relations of parts will hereinafter appear and be pointed out in the claims.

Referring to the drawings, 1 indicates the car side sills and 2 indicates the box-like center sill, the latter being formed of a pair of flanged members 3 arranged in spaced relation and having their webs 4 substantially parallel. The members 3 have lower and upper flanges, the latter being connected by a plate 5. Interposed between the members 3 is a filler casting 6 which also serves to hold them together.

' The body bolster, generally designated by the reference numeral 7, is formed of a plurality of sections 8, preferably of cast steel.

Since the two bolster sections are of identical construction corresponding parts ofeach seca tension 11 overlying the top of the center sill..

These extensions may advantageously be rigidly connected by a plurality of. plate-like members 12 respectively disposed in overlapping relation to opposite sides of the extensions and secured thereto by rivets 13.

The sections of the bolster may be also con-- nected by a bottom cover plate 14 whichfin addition to being secured to the lower marginal flanges 15 of the bolster sections byrivets 16, passes beneath and is secured to the center sill and side sills. Each of the bolster sections may advantageously be formedadjacent their outer ends with an integral push pole pocket 63.

Adjacent the outer ends of the bolster, the lower marginal flange 15 thereof, is substantially horizontal to cooperate with the horizontally disposed legs 17 of the respective side sills. From the inner edges of these legs of the side sills portions 18, of the lower marginal flange 15 on the'opposite sides of the center sill, incline downwardly toward the latter and merge into intermediate horizontal portions 19 affording surfaces to which the usual side bearing wear plates may be attached. From this point portions 20 of the flange 15 incline downwardly toward the center sill and merge into the inner vertical flanges 9 of the bolster sections. Any suitable center bearingmay be employed for pivotally mounting the body bolster on the truck bolster, diagrammatically shown at 21, the upper part 22 of the center bearing being advantageously secured to the plate 14 and a portion of the center sill:

The upper portion of each bolster section is formed as an angle 23 having flanges 24 and 25, respectively, which are relatively inclined with respect to theweb portions 26 of the bolster, the flange 25 engaging with the under-side of the floor 27' of the car and serving as a support therefor. This angle portion 23 is so formed that its neutral axis lies substantially in the plane of the webs 26 of the floor contacting flange 25 of the bolster extensions 11 being offset downwardly so as to permit the top surface of the upper securing plate 12 to lie in substantially the same plane as the top surface of the flange 25' formed on the body portions of the bolster. Portions of the bolster either directly or indirectly thus supportingly engage the underside of the floor of the car for the entire width of the latter.

By this construction the forces imposed upon the upper portions of the bolsters by the weight of the lading which may be carried in the car directly above the bolster will act in the plane of the webs of the bolster sections, thus reducing to a minimum any eccentricity which may be developed in the floor supporting portion of the bolster by reason of these vertical forces.

Each of the bolster sections is provided with a plurality of diagonal truss-like flanges 28, projecting on opposite sides of the bolllt ster webs 26. The truss flanges of each of the holster sections extend from the outer lower corner thereof upwardly and inwardly to the top angle 23 of the bolster, thence downwardly and inwardly toward portion 19- of the bolster to which the usual side bearing wear plate is attached, then upwardly to the angle 23 of the bolster and from there downwardly to the upper corner of the center sill, thence merging into the inner vertical flange 9 of the bolster.

In this manner the truss flanges are arranged to most effectively resist forces tending to distort the bolster and particularly those forces applied to the bolster whenever the entire weight of the car is imposed on the side bearings. Furthermore, it will be appreciated, that since the portions of the truss flanges which respectively merge with and, in

fact, form continuations of the inner vertical flanges 9 of the bolster sections, diverge upwardly from adjacent the top of the centersill to the top of the sections, a greater area of the sections may be overlapped by and se cured to the connecting plates 12 than would be the case should the inner flanges be disposed in a vertical plane from top to bottom of the sections, whereby a most rigid connection between the sections is obtained.

At each end the bolster is fashioned to permit a side stake 29 to be rigidly secured to the web 26 thereof, the side stakes being advantageously formed as bulb angles. For this purpose a portion of the member 23 at the top of the bolster terminates at-a point 30 inwardly of the ends of the bolster and a portion of each of the outer vertical flanges 1O "terminates at a point 31. In this manner it will be seen that the outer face of the web 32 of the bulb angle contacts with a relatively large area of the web 26 of the bolster.

and may be rigidly secured thereto by a plurality of rivets 33; the outer leg 34 of the bulb angle, when the stake is thus attached to the bolster, constituting in effect a continuation of that portion of the outer Vertical flange 10 of the bolster which terminates at 31.

The side stakes are disposed in overlapping relation to the inner faces of the car sides 35 and project into the'car body. To prevent them from interfering with or interruptingthe flow of lading down the inclined floor 27 of the car and from retaining any lading within the car, each of the bolster sections is provided with a portion 36 projecting upwardly beyond the car floor in substantial alinement with the side stakes longitudinally of the car.

These projections are formed by a portion 37 of the web 'of the bolster, a portion 38 of the outer vertical flange 10 and a continuation of a portion of the floor contacting flange 25 which extends substantially vertically upward as at 39 and then inclines upwardly and outwardly as at 40, the portions 38 and 39 respectively constituting outer and inner surfaces or faces of the projections 36. In addition to being inclined transversely of the car and extending down wardly toward the longitudinal axis thereof, the upper surfaces 40 of the projections 36 are inclined downwardly longitudinally of v the car toward the center thereof to the same extent as the floor contacting flange 25.

The car sides 35 are preferably formed of a plurality of sheets 41 overlappingly sesecured to the leg 34 of the side stake by rivets 46 and to the outer vertical flange 10 of the bolster by rivets 47.

Instead of forming the marginal edges of the floor sheets 48 with inclined portions to overlie the top surfaces 40 of the projections 36 and securing the said floor sheet to the side sheets 49, adjacent the outer end of the bolster projections 36, it is preferred to form the side sheets 49 with inwardly inclined portions 50 which terminate in down-turned flanges 51. the latter being secured to the upstanding flange of the'floor sheet, by rivets 53. One of the rivets 53 on each side of the car rigidly secures the overlapping portions of the floor sheet 48 and the side sheets 49 to the corresponding inner faces 39 of the projections. The inclined portions 50 of the side sheets may advantageously be secured to the inclined top portions 40 of the bolster projections by rivets 54.

The upper corners of the floor sheet 55 are cut away to pass around the side stakes and the marginal edges of the floor sheet are flanged as at 56, the latter overlapping a portion of the inner face of each of the legs 34 of the side stakes and the inner face of the side sheets 45 which extend downwardly and are secured by any suitable means to the upstanding legs of the respective side sills. The marginal flanges 56 of the floor sheet 55 are secured to the cooperating portions of the side stakes and side sheets 45 by rivets 57. The portion of the floor sheet 55 adjacent each of the side stakes is supported on its underside by a bracket or auxiliary member 58 which is rigidly secured to the web of the neighboring side stakes by rivets 59.

The upper surface 60 of the member 58 is inclined correspondingly to the floor contacting flange 25 of the bolster and the face of the member contacting with the side stake is fashioned with a plurality of recesses 61 and 62 for respectively receiving the protruding portion of the side stake and one of the rivets employed for securing th side stake to the bolster. The rivets 59 which secure the member 58 to the side stake also serve as additional means for rigidly securing the latter to the bolster.

It will thus be appreciated that any lading in longitudinal alinement with the stake between the car end and the body bolster will be deflected transversely of the car toward the floor sheet 48 by the inclined portions 50 of the side sheets 49. The projections 36, in addition to affording a support for the in clines 50 of the side sheets, permit a greater number of rivets to be used in securing the side stake to the bolster than would be the case with. bolsters of usual design. Since a 'major part of the force required for supsteel. sections, each of said sections having an integral upstanding plate-like extension overlying the top of the center sill and each having an upwardly extending flange terminating adjacent the top of the extension, the lower portion of said flanges affording means for respectively securing the bolster sectlons to oppositesides of the center sill and the integral extensions of the bolster sections affording means for securing the sections together.
