SPECIFICATION forming part of Letters Patent No. 745,262, dated November 24, 1903.

Application iiled August 27, 1903. Serial No. 171,007. (No model.)

T0 all whom, t may concern:

Be it known that I, ARNOLD STUCKI, a citizen of the United States, and a resident of Allegheny, Pennsylvania, have invented certain Improvements in Railway-Oar Bolsters, of which the following is a specification.

My invention consists of certain improvements in or additions to the railway-car bolster shown in my Patent No. 685,157, dated October 22, 1901, for the purpose of adapting it especially for use as a body-bolster.

In the accompanying drawings, Figure 1 is a side elevation of the bolster with parts of certain sills of the car. Fig. 2 is a view of the bolster, partly in plan and partly in sectional plan. Fig. 3 is a transverse section on the line a a, Fig. 1. Fig. 4 is a tranvers'e section on the line b l?, Fig. 1. Fig. 5 is atransverse section on the line c c, Fig. 1. Fig. 6 is a transverse section on the line d d, Fig. 1. Fig. 7 is a plan view of an element of the center bearing of the bolster; and Fig. 8 is a side view of one end of the bolster, illustrating a different construction from that shown in Fig. 1. Figs. 3 to 7, inclusive, are on a larger scale than Figs. 1, 2, and 8.'

In its general construction the bolster is similar tothat of the former patent and comprises a truss with flat top member 1 and bent bottom member 2, these members having pockets struck up therefrom near each end, so as to form abutting braces 3, which are suitably riveted together. Between the top and bottom members of the truss, at the center of the bolster, are interposed center braces 4, having top and bottom flanges riveted, respectively, to the top andbottom members, the central Webs of these braces being separated from each other, except atthe center, where the upper portion of each web is bent inwardly, so as to abut against the corresponding inwardly-bent portion of the other web, these two abutting portions being riveted together, as shown in Figs. 2 and 6.

At the center of the lower portion of each web 4. it is curved outward slightly, so as to form a socket for the reception of the upper portion of the king-bolt,which passes through a suitable opening in the bottom of the truss and in a cupped or dished center bearing 6, which is riveted or otherwise firmly secured to the bottom member of the truss and is braced and stiened vertically by means ofV an interposed block 7 ,consisting of a ring with radiating wings, as shown in Fig. 7.

At points intermediate of the center and ends of the bolster flanged stiffening-plates 8 are interposed between the top and bottom members of the truss, the flanges of these plates being riveted or otherwise secured to said truss members and their vertical webs being by preference ribbed or corrugated, as shown at 9, so as to stiffen the same and cause them to interpose greater resistance to the strains to wliichthey are subjected.

All of the longitudinal sills of the car rest upon the top member of the bolster, unless the side sills are deeper than the center and intermediate sills, in which case the top member of the bolster is discontinued at such a distance from the end of the bottom member as to accommodate said deeper side sills, against the inner face of which the top member of the bolster abuts, as shown in Fig. 1, the sills resting upon the projecting end portions of the bottom member of the bolster. In this case it is preferable to` bend downward the subjects them.

The flanges 11 of the top member of the bolster, projecting on each side of the pockets 3, are preferably stiffened by brackets 12, which may be suitably pressed up from the metal of which the top member of the bolster is composed,v as many of these brackets being employed as the car-builder may consider necessary to properly stiften these portions of the upper member of the bolster.

It will of course be understood that where the deep side sills are not employed both members of the bolster will extend to the same point and the side sills will be supported directly upon the top member of the bolster in the same manner as the center and intermediate sills. (See Fig. 8.) y

On the underside of the bolster are secured pressed strips of sheet metal forming side bearings 13 for coperation with similarbearings upon the truck-bolster.

A body-bolster constructed in accordance with my invention is very light compared with the strength possessed by it, the metal being disposed to best advantage to resist the strains to which the different portions of the bolster are subjected. The bolster is also cheap as compared with other bolsters now in use. It permits the ready passage of draftsills, brake-pipes, brake-rods, and other paraphernalia and is readily accessible in all of' its parts. Hence it can be thoroughly coated with paint or other protective material to prevent oxidation. The center brace is eX- ceptionally strong and rigid, and the labor cost of fitting together the various parts of the bolster is reduced to a minimum, very little shearing of the plates being necessary.

Having thus described my invention, I claim and desire to secure by Letters Patentl. The within-described body-bolster for railway-cars, the same consisting of top and bottom members forming a truss, these members being separated from each other by central, end, and intermediate braces, the end braces being formed by pressing pockets in the metal of the top and bottom members of the bolster, substantially as speciiied.

2. The within-described bolster for railwaycars, the same consisting of top and bottom members forming a truss, these members being separated from each other by central, end, and intermediate braces, the central brace forming a support for the center bearing of the bolster, and the end braces being formed by pressing pockets in the metal of' the top and bottom members of the bolster, substantially as specified.

3. The within-described body-bolster for railway-cars, the same consisting of top and bottom members forming a truss, thesemembers being separated from each other by central, end, and intermediate braces, the intermediate braces being composed of flanged plates, whose iianges are secured to the top and bottom members ot' the bolster and whose Vertical webs are bent or corrugated, substantially as specified.

1i. A body-bolster for railway-cars consisting of top and bottom members forming atruss, central braces interposed between said top and bottom members of the truss, a cupped or dished center bearing secured to the bottom member, and a brace or filler-block interposed between said cupped center bearing and the bottom member of the truss, substantially as specified.

5. A body-bolster for railway-cars consisting of top and bottom members forming a truss, said members being braced at the ends by means of abutting pockets struck up therefrom and the upper member being discontinued some distance from the end of the lower member so as to provide for the seating of a deep side ysill directly upon said lower member, substantially as speciiied.

6. A body-bolster for railway-cars consisting of top and bottom members forming a truss, said members being braced at the ends by means of abutting pockets struck up therefrom and the upper member being discontinued some distance from the end of the lower member so as to provide for the seating of a deep side sill directly upon said lower member, which, at and near its ends, is provided with depending side edge fanges, substantially as specified.

7. A body-bolster for railway-cars comprising top and bottom members forming a truss braced at the ends by means ol abutting pockets struck up from said members, the flanges of the top member extending beyond said pockets, being braced by means oi' brackets extending from said fianges to the sides of the pockets, substantially as specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
