Description

NITED STATES PATENT OFFICE.
HERBERT R. KEITHLEY, OF BUFFALO, NEW YORK.
UNDERFRAME RAILWAY-CARS.
SPECIFICATION forming part of Letters Patent No. 659,402, dated. October 9, 1900. Application filed August 1, 1900. Serial No. 25,520. (No model.)
To all whmn it Wwty concern:
Be it known that I, HERBERT R. KEITHLEY, a citizen of the United States, residing at Buf-- fa'lo, in the county of Erie and State of New York, have invented newand useful Improvements-in Underframes for Railway-Oars, of which the following is a specification.
The object of my invention is to provide a steel underframe for railway-cars which is comparatively light and which at the same time possesses the necessary strength and rigidity to withstand the severe shocks to which cars are subjected.
In the accompanying drawings, Figure 1 is a fragmentary side elevation of my improved under-frame. Fig. 2 is a transverse section in line 2 2, Fig. 1. Fig. 3 is a detached side elevation of the center sill.
Like letters of reference refer to like parts in the several figures.
A A are the side sills ofthe underframe. These sills are composed of longitudinal Z- bars, with their upper flanges preferably facing inwardly and each Z-bar constructed of a single plate of pressed steel. If desired, the Z-bars of each side sill may be rigidly tied together by horizontal top and bottom plates a a, which are riveted to the flanges of the Z bars, forming practically a boxgirder. The middle portion a of each side sill is made of greater depth than its end por-- tions to provide the necessary strength in that portion of the underframe, and the sill gradually increases in depth from its end portions toward its deepened middle portion,as shown in Fig. 1. e a
B is the center sill, which is constructed, substantially, like the side sills, the same comprising two longitudinal Z-bars, each constructed of a single plate of pressed steel, and, if desired, the two bars may be connected together by upper and lower plates 1) b, which are riveted to the flanges of the bars and which form a box-girder with the Z-bars. In the construction shown in the drawings the Z-bars of the center sill are placed so that their upper flanges face outwardly; but, if desired, they may be arranged to face inwardly like the upper Z-bar flanges of the side sills. As shown in Fig. 3, the middle. portion 19 of the center sill is made deeper than its end portions, similar to the side sills. If desired, the upper flanges of the Z-bars of which extend across the upper and lower' sides of said sills, and a horizontal channelbarf, which embraces said Z-bars. The peculiar construction of this end connection of the sills and the particular construction of the bolster herein shown form no part of my present invention, but are described and claimed in another application for patent filed by me April 24, 1900, Serial No. 14,093, series of 1900.
I claim as my invention- 1. An underframe for a railway-car having a side sill composed of Z-bars, each Z-bar constructed of a single plate of pressed steel and having its middle portion made of greater depth than its end portions, and top and bottom plates riveted to the flanges of said Z- bars and forming a box-girder therewith, substantially as set forth.
2. An underframe for a railway-car having a center sill composed of Z-bars, each Z-bar constructed of a single plate of pressed steel and having its middle portion made of greater depth than its end portions, and top and bottom plates riveted to the flanges of said 2- bars and forming a box-girder therewith, substantially as set forth.
3. An underframe for a railway-car having side and center sills, each composed of a pair of Z-bars and top and bottom plates riveted to the flanges of said bars to form a box-girder, each of saidZ-bars being constructed of a single plate of pressed steel and having its middle portion made of greater depth than its end portions, substantially as set forth.
Witness my hand this 30th day of Ju1y,1900.
HERBERT R. KEITHLEY.
