22 Claims. (Ci. 105228) My invention relam to railway cars and more particularly to improvements in body bolsters and the arrangement anddisposition of the body bolster with associated parts of the car 5 structure.

Heretofore considerable difficulty has been experienced in rigidly connecting the body bolster to the car center sill due to variations in the dimensions of the bolster and center sill l incident to inaccuracies of manufacture. This is especially true when cast steel bolsters are used because of the shrinkage which occurs in the casting operation. A principal object of the invention is, therel fore, to produce a body bolster of suchv design and construction that it may be rigidly secured to the car center sill notwithstanding variations in the dimensions of the bolster and center sill.

Another object of the invention is to produce a bolster having these characteristics which is especially suitable for application to drop bottom railway cars having an inclined floor sheet.

A primary feature of the invention consists in integrally forming a. body bolster which is adapted to be interposed between the car floor and center sill with portions for attachment to the car side sills and the top of the center sill.

Another feature of the invention resides in forming the bolster with a plurality of flanges v 80 disposedin spaced substantially parallel planes,

the flanges being adapted to be secured to vertically spaced portions of the .car center sill.

Another feature of the invention consists in forming the body bolster with a central horizontal flange intermediate the top andflbottom.

edges thereof for attachmentjo the top of the car-center sill.

A Other and more specific features of the invention residing in advantageous forms and combinations and relations of parts will hereinafter appear and be pointed out in the claims.

In the drawings illustrating a preferred emt of the invention:

' Figure 1 is a transverse vertical sectional view of a railway hopper car, the body bolster being in elevation, and the upper being omitted,

Figure '2 is a top view -partly in elevation and partly in section of the construction illustrated in Figure '1, portions of the inclined floqrsheets of the car being broken away, 7

Figure 3 is an enlarged fragmentary side elevational view of that portion of the bolster adjacent the center sill, the latter being in sec- 65. tiers,

portion of the car Figure 4 is a sectional view taken on line 4-4, Figure 1,

Figure 5 is a fragmentary sectional view taken on line 5-5, Figure 1.

Referring more particularly to the drawings 50 1 indicates the body bolster which mayadvantageously be cast as a unitary structure and preferably extends continuously from one side of the car to the other. The bolster is preferably formed with a substantially vertical main 85 webportion 2 and with to'p 'and bottom flangesv 3 and 4, respectively, which project on opposite side of the web. The top flange which extends continuously from one end of the bolster to the other is preferably inclined to supportingly cooperate with the underside of the inclined floor sheets 5 and 6, respectively. To obviate the necessity of offsetting one of the-sheets which is overlappinzlyi secured to the other sheet and to the top flange by rivets 7 the flange may be recessed as at 8 to l'receive the lower sheet 6. The top flange of the bolster is preferably connected to the web 2 thereof, by a portion 9 which extends at an oblique angle to the latter and at 'a right angle to the flange.

The top and bottom flanges 3 and 4 are re- 4 spectively connected by a plurality of diagonally arranged truss-like flanges 10 which intersect at points so as to evenly distribute throughout the bolster all forces and strains to which it may be subjected. Intermediate each of the truss- 7 like flanges 10 and adjacent portions of the top and bottom flanges the web of the bolster may be suitably-apertured as at 10", thereby reducing the weight of bolster without effecting its structural function. At its opposite ends the bolster is fashioned with flanges 11 which also project on opposite sides of the web 2 and serve to connect the top and bottom flanges. From the foregoing it will be seen that the body bolster is in effect a trussed girder a tension member along its upper edge and a compression member along its lower edge which are connected by diagonal and substantially vertical truss mem- The lower portions of the end flanges are suitably formedto receive the usual car side sills 12 which are rigidly connected thereto by rivets 13. The portions of the top flange adjacent the opposite ends of the bolster maybe respectively enlarged as at 14 to afford means to which suitably shaped side stakes 15 may be secured. The side stakes project upwardly from the bolster within the car side sheets 16 and each may be additionally secured to the bolster by a plate 17, which is secured to the end flanges 11 of the bolster by rivets 18 and which is interposed between and secured to the stakes and side sheets by rivets 19. The edges of the side sheets which adjoin at the ends of the bolster may. be connected by a cover-plate 20.

Adjacent its central portion the compression member of the bolster is cutaway to form a recess or opening for receiving a car center sill 21. The opening thus formed communicates with the adjacent apertures 10' with which the web 2 is provided. The center sill may be of usual construction comprising spaced beams having webs 22, inwardly projecting top flanges 23 and bottom flanges 24, the latter projecting on opposite sides of their associated webs. 1nterposed between the beams and rigidly secured to them by rivets 25 is the usual center casting 26. The beams are connected by top and bot= tom cover- plates 27 and 28, respectively, the former being secured to the inwardly projecting flanges 23 by rivets 29 and the latter to the flanges 24 by rivets 30. The bottom cover-plate 28 extends continuously from one side sill to the other and is connected to each by rivets 31 and to the flange 4 of the compression members of the bolster by rivets 32. Thus it will be seen that although the compression member is cut away adjacent its central portion the component parts thereof are rigidly connected and tied together by the bottom plate 28.

The portions of the compression members adjacent the sides of the center sill are disposed in spaced relation to the latter to compensate for variations in dimensions of the center sill and bolster and the bottom flange 4 of the bolster is fashioned to overlie the upper surfaces of the outwardly projecting portions of the bottom flanges 24 of the center sill beams. To permit a relatively large number of rivets 33 to be employed for the purpose of rigidly connecting the compression members to the bottom flanges 24 the flange 4 of the bolster is preferably enlarged as at 34. The rivets 33 in addition to securing the bolster and center sill together serve as additional means for connecting the bottom coverplate 23 'to the latter.

Underlying the bottom cover plate 28 is a center bearing plate 39 which is secured to the bottom flanges 24 of the center sill by rivets 30 and 33. In order to strengthen the connection between the compression members of the bolster the center plate 39 extends beyond the flanges 24 and is rigidly secured outwardly thereof to the bottom cover plate 28 and the compression members. Since the compression members incline upwardly and outwardly from adjacent the center sill this construction is particularly desirable as the forces transmitted to the cover plate 28 from the compression members tend to buckle the plate where it angles upwardly.

Projecting downwardly from the tension member of the bolster is a substantially vertical column member or strut 35 which comprises a web portion 36, a substantially horizontal flange 3'7 and vertical flanges or ribs 38.

The horizontal flange 37 and the ribs 38 project on opposite sides of the web 36 and the latter in effect constitutes a part of the main web 2 of the bolster. The flange 37 which is of a width substantially equal to the distance between the webs of the beams of the center sill contacts with the upper surface of the top cover-plate 27 of the center sill and is secured thereto and to the inwardly projecting flanges 23 by rivets 29 heretofore described. The ribs 38 rigidity the horizontal flange 3'7 and serve to connect this flange with the top flange 3 of the bolster, the ribs meeting the flange 3 adjacent the point of intersection of the diagonal flanges 10 which diverge downwardly on opposite sides oi the center sill. Since the flange 37 extends a greater distance on opposite sides of the web 2 of the bolster than does the top flange 3, the side edges of the ribs 38 converge upwardly.

From the foregoing it will be perceived that by riveting the portions 34 and 37 of the bolster to the flanges 24 and 23 of the center sill, respectively, a very rigid connection is obtained between these parts of the car structure. Furthermore it will be observed that since no part of the bolster is secured to the sides of the center sill the width of the latter may vary between certain limits without in any way eflecting the rigidity of the connection between the bolster and the center sill.
