UNDERFRAME FOR CARS.

Specification of Letters Patent.

Patented Aug'. 20,1912.

Application filed October 26, 1910. Serial No. 589,097.

To all whom t may concern;

Be it known that WILLIAM l. Brrr'rnivnolrr, deceased, late a citizen of the United States, residing at Bettendorf, in the county of Scott and State' of Iowa, did invent certain new and useful Improvements in Underframes for Cars, of'which the following is a full, clear, and. exact description.

This' invention relates more particularly toy the 'underframes of railway cars, and vparticularlyto the cars described and illustrated in an application for Letters Patent of the United States, tiled. by l/Villiam P. Bettendorf, deceased, May 16th, 1910, Serial No. 561558'.

The principal object` of this invention is lto obtain such a construction of the underframe that the center of gravity of the car can be ylowered considerably. and yet possess that resiliency or yielding quality which it is so desirable to have, particularly in steel cars.

A further object of this invention is to obtain a strong and durable construction that can be economically made.

These and other objects are accomplished by the means hereinafter fully described and as particularly pointed out in the claims.

In the drawings z-Figure 1 is a plan View bodying this invention. Fig. 2 is a transverse vertical section of the same, taken' on dotted lline 2, 2, Fig. l. Fig. 3 is a longitudinal vertical section, taken on dotted line 3, 3, Fig. 1. i l

The principal elements of the underfraine to Which this invention relates, comprise the body-holsters, the center-sill and draft-sills, or equivalent structure therefor. The bodyholsters A are made of cast metal and I prefer to make them hollow in order to lessen their Weight as `much as possible. The outer ends, of these body-holsters are provided with integralbra'ckets o, that exten in a transverse upward direction to the running-board E of the car, which latter 1s riveted to the ends of the same.

At their centers of length the body-bolstersare provided with pockets B that eX- tend lengthwise of the car in the vert-ical plane of the king-bolt C. These pockets are adapted to contain coiled springs or other tion. The underside of the bo ster, A., at its center of length, .is provided with a male centeringr plate which is seated in the 0b- \'crse centering plate of a suitable truckbolster X. The rear side of this bolster is provided with wings D, D, thc inner vertical surfaces of which are parallel and are arranged so as to be an equal distance from the vertical longitudinal plane of the kingbolt, and the upper flanges of these wings are bent .outward and are otherwise constructed to afford means to which the flanges of a horizontally disposed I-bearn center-sill F can be secured by rivets -or otherwise. This horizontally disposed single I-beam center-sill extends longitudinally from one body-bolster to the other, its web is horizontal and may be recessed as at F at its ends `to accommodate the central enlargements of the bolsters in which the pockets B are made, and likewise the devices used in connection with said pockets. The upper flanges at the ends of the I-bcam web are bent or curved outward, and areri'veted or otherwise secured t the curved flanges of the wings D, D. This bending of-the flanges of-thc wings D of the bolster, and the upper flanges of the center-sill enables the body of the car tobe lowered, and as the ends of these center-sill flanges abut against the rear surface of the body of the bolster, the shearpreferably. I-shaped in cross section and,

converge toward each other until they reach a point slightly to the rear of the draft-rigging (not shown). From this latter point said draft-sills have 'their opposing inner surfaces parallel to cach other. and provided with suitable integral stop-lugs for the usual follower-plates of said draft-rigging, and have their forward ends connected by a cross-member g. both above and below the draw-bar opening.

-VVhat l claim as new is B1. ln a railway car. a center-sill consisting of a single integral I-beani, the web connecting the flanges of which is horizontally disposed and the upper flanges of which are flared outward.

2. In a railway car, a center-sill consisting of asingle integral rolled metal beam having a horizontally disposed Web and upwardly projecting flanges that are flared outwardly.

3. n a railway car, a center-sill consisting of a single integral. rolled metal beam extending from lbolster to bolster and se-A having a horizontally disposed Web and up Gomes of this patent may be obtained for wardly flared flanges and having openings adjacent the ends of its web.

. v7. Ina railwaycar, a center-sill consisting of a single integra-l "1I-beam extending from bolster to bolster and secured thereto the web connecting' the flanges of which is horizont-ally disposed and provided with openings adjacent its ends.

8. In a railway car, a center-sill consisting of a single integral I-bearn the web connecting the flanges of which is horizontally disposed and provided With'openings adjacent its ends, and the upper anges of which are flared outward. f
