SPECIFICATION forming part of LettersI'atent No. 776,045, dated November 29, 1904. Application filed May 5, 1904:. Serial No. 206,551. (No model.)
To t/Z whom, t may concern/.-
Be it known that I, SAMUEL Pensoorfi Busi-I, a resident of Oolumbus, in the coun ty of Franklin and State of Ohio, have invented certain new and useful Improvements in Bolsters; and
I 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 to which it appertains to make and use the same.
My invention relates to an improved bolster, the object of the invention being' to provide an improved bolster of minimum Weight and maximum strength and which shall be of simple construction and neat and attractive appearance.
With this object in view the invention consists in certain no vel features of construction and combinations and arrangements of parts, as will be more fully hereinafter described, and pointed out in the claims.
1n the accompanying drawings, `Figure l is a view in side elevation illustrating my improvements. Fig. 2 is a top plan view. Figs. 3, 4, 5, and 6 are views in section on thelines c e, o c, and l d, respectively, of Fig. l; and F ig. 7 is a side view of a modification.
My improved bolster, which is preferably one integral casting, comprises, in the main, top plate or member 1 and bottom plate or member 2, spaced the greatest distance apart at their centers, Where they are connected by a center strut 3 and converging toward their ends, the lower member, 2, having an appreciably-greater incline than top member l and contracted laterally throughout its central or intermediate portion, as shown. Upper member 1 at both side edges is provided with depending langes 11, which join the bottom member 2 throughout that portion thereof adjacent to its ends, and said upper member l is provided with center bearing 4c and side bearings 5. Lower member 2 projects beyond the ends of upper member' l, is rounded and provided with streng'thening-iianges 6, and spring seats or posts 7 are located centrally of the bottom member near itshends and below the recessed ends of the upper member. The sides of the bolster near its ends are `tlairged, forming bearings 8 for the truckposts and strengthen the bolster, and the bolster is preferably lightened by numerous openings 9.
The center strut 3 is shown with lateral strengthening-ribs 9 at its upper end, connecting the same with top member l andside flanges 1l, and in addition Ato these ribs, which may extend throughout the length of the post, it may be provided with various other sti'engtlieningl'ibs located longitudinally or laterally of the bolster, or both, if desired.
In Fig. 7 the bolster is shown as havingthe side flanges of the top member l forming the central strut as they continue down to and join the bottom member 2.
The bottom member 2 may have side [i anges or not, as preferred, the post may have radiating ribs, the bottom member may havelongitudinal ribs, the ends may have a central web connecting the upper and lower members, and the ends may have cross-ribs, and a great many other changes might be made in the general form and arrangement of the parts described without departing from my invention. Hence I do not restrict myself to the precise details set forth, but consider myself at liberty to make such slight changes and alterations as fairly fall within the spirit and scope of my invention.
Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. A bolster, consisting of atop member, a bottom member, a central strut connecting said members, and side flanges on the top member connecting' the same with the bottom member at `its ends only, all of said parts be ing cast integral.
2. A bolster, consisting of a top member, a bottom member, a central strut connecting' the top and bottom members, side iianges on the top member connecting the same with the bottom membcrat its ends only, and all of said parts comprising one integral casting.
3. A bolster. consisting of a top member, a bottom member, a central strut connecting' them, side flanges throughout the length of the top member connected with the bottom at the ends of said members, all of said parts member at the ends thereof, ribs connecting being east integral.
the Center strut, top member, and side llanges, ln testimony whereof 1 have signed this and all of said parts comprising one integral specification in the presence or' two subscrib- 5 casting. -ing Witnesses.
4. A bolster, conslstmg or top and bottom SAMUEL PRESGOTT BUSH* members,a central strut connecting said members and comprising their sole connection at Witnesses:
the center, and side flanges Connecting the FRANK J. TOWN, IO members and comprising the sole connection J. lV. GLAZER.
