My invention relates to railway cars and more particularly to improvements in body bolsters. s

A principal object of the invention is to provide a body bolster of simple and rugged construction especially suitable for hopper cars. Another object of the invention is to provide improved means for rigidly connecting the bolster to associated parts of the car structure.

A principal feature of the invention consists in constructing the body bolster with top and bottom plate members, the top mem-v ber affording a support for the car floor and the bottom plate member having a portion for attachment to the top of the car center sill.

Another feature of the invention resides in providing a body bolster having a bottom plate member adapted to be secured to the top of the car center sill with a plur'ality of depending portions afiording means to which side bearing wear plates may be respectively secured.

A further feature of the invention consists in constructing a railway car with a body bolster adapted to rest upon and be secured to the top of the car center sill, the bolster being provided with depending portions af fording means to which side bearing wear plates may be respectively secured, and in associating therewith a plate passing beneath the center sill and secured thereto and to the depending portions of the bolster for rigidly connecting it to the center sill.

A still further feature of the invention resides in constructing a body bolster with end walls provided with substantially vertical recesses for respectively receiving car side stakes.

car center sill with a plurality of pairs of depending members, one pair of said members affording means to which side bearing wear plates may be attached and the other pair of said members aflording means to which car side sills may be respectively attached.

Figure 13 is a view similar to Figure 10 showing amodified form of the invention.

Referring more particularly to the drawings, 1 indicates the box-like center sill having two sill members 2, each being provided with a web 3 and top and bottom flanges 4;

and 5, respectively. The sill members may rigidly connected thereto by rivets 10 is the usual center casting or filler member 11.

The bolster 12 which may advantageously be formed as a unitary casting and which is adapted to be interposed between the car floor and car center sill, is provided with an inclined top plate member 13 and a substantially horizontal bottom plate member 14. The top plate member 13 is arranged to lie in a plane parallel with the inclined floor sheets 15, the latter being supported thereby and overlappingly secured thereto by rivets 16. The bottom plate member 14 extends substantially continuously from one end of the bolster to the other and the central portion thereof rests upon and is rigidly secured to the top of the center sill. The rivets '7 employed for connecting the top cover plate 6 of the center sill to the sill members thereof may be employed for securing the bottom plate member 14 of the bolster to the center sill and the portion of the bottom plate member engaging the center sill is preferably enlarged as at 17 so that a large number of rivets may be employed for obtaining a very rigid connection between the bolster and center sill. Depending from the lower plate member 14 on opposite sides of the center sill are members 18, respectively, affording means to which side bearing wear plates 19, of any usual construction, may be secured. These depending members are rigidly connected to the center sill by means of the bottom cover plate 8 and rivets 20, the latter also serving as connecting means for the side bearing wear plates 19.

The top and bottom plate members of the bolster are preferably connected by a substantially continuous system of transverse webs. As the webs in one half of the bolster are arranged in the same manner as the webs in the other half thereof and have similar functions, the corresponding webs in each half are designated by similar reference numeralsf Adjacent the center of the bolster the top and bottom plate members are connected by two substantially vertical webs 21 which are respectively preferably arranged substantially in the same planes as the webs 3 of the sill members 2. In will thus be seen that the load imposed upon the top plate of the bolster adjacent thecenter thereof will be transmitted through the transverse webs 21 directly to the sill members 2. etween the ends of the bolsterand the respective vertical webs 21 the top and bottom plate members are also connected by transverse substantially vertical webs 22, respectively disposed in planes intersecting the surfaces of the downwardly depending members to which the side bearing wear plates are secured. The adjoining vertical webs 21 and 22 are each connected by transverse diagonal webs 23which respectively extend upwardly from the point of intersection of the webs 21 bolster therein. To efl'ectually resist these bending I they intersect substantially half way between the vertical webs 22 and the ends of the bolster. At their ends the top and bottom plate members are connected by end walls 25, which -will be hereinafter described in detail. Due

to the arrangement of the connecting webs, it will be appreciated that the forces incident to the weight of the car and its contained lading are transmitted through the body bolster to the car truck (not shown) in a manner such that they are evenly distributed through the bolster, thereby preventing undesired concentration of forces at particular points in the bolster.

As is well understood, bufiing forces to which railway cars are subjected, are communicated to the car center sill and from there transmitted to the. body bolster and thence into adjacent parts of the car construction. Due to the inertia of the car body and because the outer ends of the bolster are rigidly secured to the side sills of the car, the buffing forces thus communicated to the induce severe bending stresses forces the portion of the bolster intermediate the vertical webs 22 is formed with side plate members 26, which respectively connect the marginal edges of the top and bottom plate members, the vertical webs 21 and 22, and the diagonal webs 23 thereof. As the bottom plate membe'r'is slightly wider than the top plate member, the side plates 4 26 diverge slightly downwardly and in order to reduce the weight of the bolster with-v out affecting its strength, they may be suitably apertured as at 27. Each of-the apertures is preferably of a shape similar to that formed ,by adjacent portions of the top and bottom plate members and the neighboring transverse webs. The portions of the side plates bounding the openings may, if desired, be formed with rigidifying beads or ribs 28. From the foregoing it will be seen that the central portion of the body bolster is in effect a trussed girder having upper and lower chords connected by diagonal and substantially vertical truss members, the upper and lower chords and the outer vertical members being of substantially channel section and the diagonal and inner vertical members being substantially I-section. The

enlarged portion 17 of the bottom plate preferably centrally disposed webs 30, which .vertical webs 22to the end wal 525.

from the respectively extend continuousl This 7 web may be formed with apertures31 similar to'thoseformed in the side plates 26. From the foregoing it will be observed that adjacent its end portions, where bending moments are a minimum, the bolster is of substantially I-section while adjacent its cen-' tral portion, where bending moments are greatest, the bolster is of substantially box section. In order that the neutral axis of the top plate member adjoining the longitudinal webs 30 may lie substantially in the plane of the latter, the upper portion of the webs incline'upwardly,-as at 32, in a direction opposite to that of the top plate member, intersecting it at substantially right angles. To prevent undue concentration of load in the vertical web members 22 adjacent the point where they intersect with the bottom edges of the inclined portions 32 of the lon gitudinal webs 30, they are connected adjacent this point tovthe diagonal webs 23 by inclined webs 33. Thesewebs 33 are disposed in a plane-substantially parallel to the top plate member and incline downwardly from the adjacent lower edge of the inclined portions 32 of the longitudinal webs 30 and intersect with adjacent portions of one of the side plates 26. Thus continuity of the force reaction furnished by the bolster is assured.

Each of the depending members 18 is formed with a web 34 and a bottom plate 35, the latter affording the means heretofore described towhich the side bearin wear plates 19 are secured. In order to rigidify the depending members, each is provided with a pluralityof flanges36 and 37, the flanges 36 being arran ed in spaced relation and pro jecting inwar 1y, from the. web 24 toward thecenter sill and the flange 37 being disposed in a plane intermediate the planes of the flanges 36 and projecting outwardly from the web toward the adjacent side sill. All of the flangesmay be suitably reinforced by marginal ribs or beads 38. The flanges 36 are preferably disposed in the plane of the V neighboring side plates 26 and, in effect, constitute continuati'ons thereof, while the flanges 37 are disposed in the longitudlnalwebs 30 and likewise constitute prolongations thereof; As the bottom plate members 35 of the depending members 18 are of a width greater than the bottom cover plate 8, the webs 34 thereof project on opposite sides of the flanges '36 and they taper upwardly so that their upper portions will be of a width corresponding to that-of'the bot- 1 tom plate member 14. j The respective outer ends of the longitudinal webs 30 are bifurcated to form substantially vertical recesses 39 in the end walls 25 of the bolster to receive suitably shaped car side stakes. In the preferred embodiment of the invention, the recesses formed in the ends of the bolster are substantially V-shaped and receive correspondingly shapedside stakes 40. The side stakes are formed with laterally projecting flanges rigidly secured in overlapping relation tothe outer face of the end walls 25 by rivets 41. In order that a very rigid connection may be obtained between thebolster and'side stakes, the latter extend downwardly to apoint adjacent the bottom plate member 14. It will, of course, be appreciated thatmany forms of side stakes may be employed which may or may not necessitate a modification in the end formation of the bolster. In :Figure 13, a side stake 42of T-section is illustrated, the T being arranged so that its stem'43 projects into the recess formed :inthe end of the bolster andso that-its flange 44 may be ov erlappingly secured to the outer face of the end wall of the bolster. IVhile the major'portion of the outer face of eachof therecesses'in the ends of the bolster are smooth andsubstantially continuous, the portion45 thereof adjacent the intersection of the top plate member and the inclined portion 32'of-the web is cut away to obviate the necessity ,of using cores at this point in the casting operation of the bolster. Should this portion Lofthe recess be formed similar to other portions thereof, it will be appreciated that it would be necessary to use cores in the angles formed by the top plate member, the inclined portions 32 of the longitudinal webs 30 andthe adjacent inner sur face of theend walls of .the bolster.

, Although the side stakes extend continuously from adjacent the bottom of the \bolster to the top of the car, the latter portion of the car construction is not disclosed as it forms no part of the invention. The side sheets 4620f the car are overlappingly secured to the outer faces of the flan es .of the side'stakes by the rivets 4'1, emp oyed for connecting the sidestakes to the bolster, and by the rivets 47. If desired, 'the adjoining ends of the side sheets may be connected'by a plate 48 which also "functions to close the recess formed in theouter faces of theside stakes illustrated in the preferred embodiment of theinvention." The marginal side plane of the wedges of the floor-sheets 15 may beflanged upwardly, as'at 49, and secured to'neighboring portions of the side sheets by any suitable one end of the cal to the other,.it is preferred to make them in sections, and 51, respectively. The sill 50,-which extends continuously from the bolster to the adjacent end of the car, is of greater depth than the sill 51, which extends from one body bolster of the ear to the other. Each is formed with a web52 and a bottom flange 53, which are respectively connected in overlapping relation byrivets 41 and 5-1 to the end walls of the bolster and the inturned bottom thereof. r

From the foregoing it will be perceived that not only is the'bolsterof such design that it will withstand the severe service conditions to which it is subjected but that its design is such that it may be easily and rigidly connected to the various parts of the car structure.
