To a/ZZ whom t may concern:

Beit known that we, SAMUEL P. BUsH and JOHN H. MCCORMICK, of Columbus, in the county of Franklin and State of Ohio, have in- 5 vented `certain new and useful Improvements in Bolsters for Cars and Car-Trucks; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art :o to which it appertains to make and use the same.

Ourinvention relates to an improvement in holsters for cars and car-trucks, its object being to provide a cast-steel bolster constructed rable in use, of light weight, and capable of being manufactured at a comparatively small initial cost.

With these ends in view the invention con- `zo sists in certain features of construction and arrangements of parts, as will be hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure l is a View in side elevation. Fig. 2 is a plan view.

z 5 Figs. 3, 4, and 5 are transverse sections taken,

respectively, on the lines aa, b b, and c o of Fig. 1.

One member or plate 1 is downwardly inclined from the center-bearing 2 to the oppo- 3o site ends of the bolster, while the other member or plate 3 is preferably made straight throughout its length. At each end of thebolster the top and bottom members are united by the short side webs 6 6 and the central Webs 5,

3 5 the latter extending from the outer end of the bolster inwardly to a point 9 and inside the inner ends of the side Webs 6 6 and from the point 9 to the central web is divided into two ribs l0 10, which extend inwardly a considerable distance and merge into the top and bottom members. Depending flanges-11 are formed on the side edges ofthe top member 1 at the central portion of the bolster,while upwardlyprojecting anges 4 are formed on the side edges of the bottom member 3. It will be observed that the side webs 6 6, central webs 5, and side lianges 11 and 4 are constructed so 15 in such form asto render it strong and du-- that their ends overlap one another, so as together constitute continuous strengthening `flanges or ribs extending the entire length of 5o the bolster.

The center column or pillar 2 is reinforced and strengthened by the longitudinally and transversely arranged Webs 7 and 8, which connect the top and bottom members and serve to strengthen the central portion of the bolster and its center-bearing.

A bolster of the form and construction above described is adapted to be made of cast-steel and produced at a low initial cost. The dis- 6o position of the metal entering into its construction is such as to produce a bolster of minimum weight and of great strength and stiffnessto resist transverse shocks and strains resulting from blows or shocks imparted to a car in the direction of its length.

Having fully described our invention, what we claim as new, and desire to secure by Let- -ters Patent, isd

l. A cast-steel bolster comprising top and 7 0 bottom members having side connecting-Webs at the ends only and having central webs cast integral with opposite ends and terminating at points inwardly removed from the center of the bolster.

2. A cast-steel bolster consisting of top and bottom members each having cast integral therewith a vertical ange on each of its side edges which extend along the central portion of the bolster, substantially as set forth. 8o

3. A cast-steel bolster consisting of top and lbottom members having their ends connected by side and center webs and provided with side flanges all cast integral with the top and bottom members, substantially as set forth.

In testimony whereof we have signed this specification in the presence of two subscribing witnesses,
