Specification of Letters Patent.

Patented Mar. 25, 11913.

To all whom it may concern.

Be it known that I, CLARENCE H. How- ARD, a citizen of the United States, residing at St. Louis, Missouri, have invented a certain new and useful Improvement in Cast-Steel Underframes for Cars, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is atop plan view of the tender underframe; Fig-2 is a longitudinal sectional view taken on line 22' of Fig.1, and Fig. 3 is a vertical sectional view .on line 3-3, Fig. 1.

This invention relates to new and useful improvements in cast steel underframes for locomotive tenders and other railway rolling stock, the object being to construct a device of the character described which can be cast in one piece and which embodies a novel arrangement of flanged bars and reinforcing webs, all as will hereinafter be described and pointed out in the claim.

In the drawings, 1 indicates the longitudinal members, 2 the transverse members, 3 the bolster members, 4: the front end sill, and 5 the rear end sill.

Usually, in tender underframes, a pocket coupler is employed between the tender and the locomotive, but, in this instance, the tender-underframe is provided with housings at each end to accommodate draft gearing other than the pocket coupler type and therefore special means are arranged between the longitudinal member's, the end sills and the bolster members. This means consists of a horizontally disposed web .6 at each end of the underframe which web is coincident and cast integral with the bottom flanges of the members which it connects, to wit, the end sill, bolster member and the two central longitudinal members. Extending above and below this web and cast integral therewith are walls 7 forming a housing for the draft rigging, said walls being strengthened by vertical webs or flanges 8, which are integral with the webs of the central longitudinal members 1, the

inner faces of said walls being provided with lugs or shoulders 9, and horizontal outwardly presented flanges 13 adapted for the attachment of the draft gear supporting plates. The portions of the wall 7 extending below the web 6, are connected to the web 6 and to'the longitudinal members 1 by means of downwardly extending flanges 11 which extend to the bottom edge of the walls 7. The vertical flanges 8, which are cast upon the top of the wall 7 and formed integral with the draft members 1, are connected to the draft members 1 by their corners only, as is illustrated in Fig. 3,-apertures 12 being left intermediate the corners for the purpose of allowing for the expansion and contraction of the connected members from temperature. To take care of leakage from the tank and avoid accumulation of water upon the horizontally disposed web, there are provided drainage ports 10 therethrough at approp'riate points.

A tender frame constructed as above described is exceedingly simple and strong, and is not liable to be broken in service. It may readily be molded, and, as the parts are all cast integral, the absence of fastening devices prevents the parts from becoming loose.

I claim:

- In a cast steel underframe having longitudinal draft sills provided with upper and lower flanges, and a horizontal web coincident with the lower flanges, a draft gear housing comprising a casing having a to wall extending above said horizontal we and side walls extending below said horisignature in the presence of two witnesses,

this 13th day of June, o. n. HOWARD.
