CORNELIUS VANDERBILT, OF NEW YORK, N. Y.

TRUCK-BOLSTER.

SPECIFICATION formingpart of Letters Patent No. 735,044, dated July 28, 1903. Original application filed July 26, 1902, Serial No. 117,073. Divided and this application filed February 20, 1903. Serial To (tZZ whom it may concern.-

Be it known that I, CORNELIUS VANDER- BILT, a citizen of the United States, and a resident of the borough of Manhattan, city and State of New York, have invented certain new and useful Improvements in Truck-Bolsters, of which the following is a specification.

This application is a division of an application filed July 26, 1902, Serial No. 117,073.

Certain features of the bolster herein shown and described are claimed in the application of which this is a division and also in application Serial No. 110,139, filed June 4, 1902.

The object of my invention is the production of a bolster characterized by great strength combined with lightness. The bolster is preferably cast in a single piece, steel being the metal best suited for the purpose. If desired, however, the bolster may be constructed or built up of one or more pieces of rolled, pressed, or cast metal, and I donot desire to limit my invention to a bolster constructed of a single piece of cast metal, but refer to the appended claims to point out and define my invention.

In the accompanying drawings, Figure 1 is a plan, Fig. 2 a side elevation, partly in section, and Fig. 3 an end elevation, of my improved bolster.

The truck-bolster comprises an upper web 4 and a lower web 5. These webs are separated at their middle portions and gradually converge toward their ends until they unite, forming a single web 6. The side bearings 2 of the bolster are located between the center bearing 1 and the point of junction of the webs 4. and 5. This construction renders the bolster stronger for resistinglateral and other stresses imparted thereto by the side bearings than would be the case if the side bearings were located beyond the said point of junction.

The bolster is further provided with front and rear walls 7, which extend from the top web 4: to the bottom web 5, whereby the bolster is formed as a hollow beam. For convenience in casting and for lightness the ap- (No model.)

ertures 10 may be formed in the said walls. The center portions of the walls 7, however, are preferably continuous, as shown at 11. The walls 7 preferably extend from one end of the bolster to the other, the portions 9 of the said walls depending from the webs 6 at the ends of the bolster. The lower edges of the portions 9 are united by a horizontal web 8, which may serve as a spring-seat for the ends of the bolster. The

parts

6, 8, and 9 together form a box-like structure approximately rectangular in cross-section and having open ends which contribute to the lightness of the bolster.

Preferably, although not necessarily, the middle portion of the bolster is provided with transverse braces 12 and a longitudinal brace 13, which unites the upper and lower webs 4. and 5 and walls 7. It is evident, however, braces may be omitted, if desired.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

1. A cast-metal truck-bolster having ap proximately rectangular, box-section, open ended ends, and longitudinal top andbottom members,said members beingintegral at their ends and forming one wall of said box, substantially as described.

2. A truck-bolster having top and bottom webs, separated at their intermediate portions and united at their ends, front and rear walls depending from said united ends, and a web connecting the lower edges of said front and rear walls, substantially as described.

3. A truck-bolster comprising top, bottom,

front and rear walls forming a hollow beam,

said top and bottom walls being united at their ends, and a web uniting the lower edges of the ends of said front and rear walls, substantially as described.

In witness whereof I have hereunto signed my name this 19th day of February, 1903. CORNELIUS VANDERBILT. In presence of JAMES J. Cosonovn, DELOS HOLDEN.
