To all whom it may concern.-

Be it known that I, SPENCER O'IIS, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, am

the inventor of certain new and useful Improvements in Body-Bo'lsters for Railway- Cars, of which the followingis a specification.

My invention relates to that class of bolsters having an upper compression member, Io a lower ltension member removably attached tolsuch compression member, and struts arranged between the compression. and tension members provided with means for holding the main sills, subsills, and truss-rods and permitting such sills to be removedwithout disturbing the upper compression member or truss-rods. Y l p The principal object of the invention is to provide a simple, economical, and efficient zo body-bolster for railway-cars. 1

A further objectof the invention is to provide a body-bolster for railway-cars having an upper compressionmember and a lower tension member removably attached thereto,

2 5 with struts arranged therebetween having pockets adapted to receive and removably holdthe car-sills, so as to efficiently hold the sills in the struts and permit their removal by moving thelower tension member without 3o disturbing the upper compression member.,

Afurther object of the invention is to provide a bolster comprising the above elements, in combination with a central bearing-plate extending outward longitudinally of the bol- 3 5 ster beneath the sill-supporting struts, whereby such bearing-plate serves l to materially strengthen the bolster and support the sills.

A further object is, to provide a body-bolster with struts adapted to receive and hold 4o the sills of a car removablyV therein and a removable lower tension member so arranged in connection therewithas to permit the removal of the sills without disturbing either the upper compression member of the bolster or the sill-bearing struts,such struts also servin g to brace the bolster, so as to prevent transverse play.

Other and further objects of the invention will appearfrom an examination of the draw- 5o ings andthe following description and claims.

the upper compression member.

The invention consists in the features, combinations, and details of construction herein- A after described and claimed.

In the accompanying drawings, Figure lis alongitudinalelevation of'abody-bolster con- 55 structed in accordance with my. improvements, Fig2, a plan view thereof; Fig. 3, a view in elevation of one of thesill-bearing struts; Fig. 4, a sectional plan viewof the strut shown in Fig.,3, taken on line 4; and 6o Fig. 5, a transverse sectional view of the bolster, taken on line 5A of Fig. l. In constructing a bolster'in accordancewith my improvementsl I provide an upper'metallic compression member ct, having downwardly-extending metallic web portions b, attached thereto by means of; angle-irons c and rivets d, such compression member being also provided with curved outer ends e and bolts f for strengthening the parts and hold- 7o ing them firmly together. A lower metallic tension member gis provided and removably attached to such compression member and Web portions by means of angle-irons h, arranged on both sides of the web. These angle-irons are riveted to such tension member by means of rivets and removably attached lto the web by means of bolts j, which extend through perforations in the angle-irons of the lower tension member and through the web 8o portions above described, so as to hold the lower tension member removably attached to v Bolts k also Y extend through both the upper compression and lower tension members, at each end thereof, and,together with the bolts and angleirons already described, serve to still more securely hold the lower tension member removably in position. A metallic Vcenter strut Z is mounted intermediate the upper and lower 9o forsupporting truss-rods r, so that the entire Ioo weight supported by such truss-rods rests directly over the center of such side-wall portions, the upper ends of which are connected downwardly-extending side flanges w, adapted to engage the lower tension member of the.

bolster and hold the parts in position. Each of the side struts is also provided with a standard portion y, extending upward from the base and having a pocket 2 at its upper end and immediately over the center thereof adapted to support a truss-rod 3 therein. The inner side of each of such struts is provided with horizontal walls 4 and 5 and a perpendicular wall 6 at right angles thereto, all extending outward transversely of the bolster and forming a pocket adapted to receive and hold in position a sill 7 and efficiently brace the bolster and sills with relation to each other. The lower portion of the inner side of each of these side struts is provided with a perpendicular wall 8, adapted to rest against a sub or draft sill 9, and, together with the center strut and the removable tension member, hold such subsill removably in position between them. lThe above elements of each side strut are all connected by lneans of an integral web 10, and the perpendicular wall of the upper pocket portion is provided with perforations 11 for receivinga bolt 12 therethrough, which passes through the sill 7 in such pocket and the' main center sill 13 ofthe car, so as to hold such sills firmly in position and at the same time permit them to be removed upon the removal of the lower tension member without disturbing either the upper tension member or the struts. The struts are all preferably' attached to the upper suspension member by means of rivets 14.

The perpendicular wall of the upper pocket portion of each of the struts is of such length, as shown in Fig. 2, as to greatly exceed the width of the upper tension member, and as the inner face thereof rests snugly against the sill, which is mounted in the pocket, it will be readily seen that these struts not only serve to firmly hold the sill in position, but serve as a material strengthening-brace for the bolster, bracing the bolster transversely, longitudinally,and perpendicularly, thus adding greatly to the rigidity of the car.

In order to still further perfect the eciency and strength ofl the bolster, a center bearing-plate 15 is provided, comprising a circular base or bearing portion 16, having end portions 17, which extend outward therefrom beneath the sills and to the outer edges of the sill-supporting pockets of the sidev struts. This bearing-plate is attached to the lower tension member by means ot'- bolts or rivets 18 or in any ordinary and well-known manner, and as it extends entirely beneath the sills and the sill-supporting pocket portions of the side struts it will be seen that it adds materially to the strength of the bolster and serves not only as a. bearing-plate, but also in the capacity of a sill-supporting member. Side bearing-plates 19 are attached to the lower tension member, near the opposite ends thereof, by rivets 20 or in any ordinary and well-known manner and are removable with such movable tension member.

The opposite ends of the lower tension member extend downward and toward the center at an incline from the ends of the compression member, and being connected, as above described, to the web portions of the bolster and to the upper member it will be readily seen that the parts are well adapt-ed to stand' the great stress and strain to which they are subjected and at the same time provide the lightest possible construction consistent with the strength required. It will also be readily understoodby those skilled in the art that the side struts, being provided with pockets at the upper ends thereof which open inwardly, are adapted to eiciently hold the sills of the car therein mounted and form a material brace between such sills and bolster. In this way great rigidity of the parts is as required. The center sills or sub or the draft sills, and particularlyv the latter, .may thus be readily removed and new sills replaced without disturbing the upper tension member of `the truss-rods. It will also be seen that although the lower tension member when in position is held lrigidly in place, as above described, it is readily removable and serves, in connection with the transversely-extending pocketed struts and elongated bearing-plate, to form a very eficient bolster, well braced in all directions with relation to its respective parts and also with relation to the car-sills.

It is desirable that the extreme outer ends of the bolster be made as strong as possible and that the angle of the upper compression member and the inclined portions of the lower tension member be maintained substantially as shown in Fig. 1, so as to afford a high degree of strength and employ as light a construction as possible in connection with the other advantages of a built-np bolster. A pair of filling-plates 22 is therefore mounted at each end of the bolster on4 opposite sides of the webs and between the transversely-extending flanges of the upper compression and lower tension members, and the ends 23 of the upper compression member are bent inward, so as to engage the extreme ends 24 of the lower tension member, the parts being held in position, as already described, by means of bolts k and f. By this construction of the outer ends of the bolster it will be seen 'that the weight, which rests upon the extreme ends ofthe bolster, may be sustained with the same efficiency substantially as if the lower tension member and its langle-bar extended` IOO upper compression member, a lower tension member` removably attached thereto, and strut mechanism mounted intermediatesuch members and provided with pockets for receiving and removably holding center sills of the car-frame, substantially as described.
