CAST-STEEL UNDERFRAME FOR CARS.

To all whom it may concern:

Be it known that I, CLARENCE H. HOWARD, a citizen of the United States, residing at St. Louis, Missouri, have invented a certain new and useful Improvement in Castateel Underframes for Cars, of which the follow ing is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in wh1ch Figure l is a top plan view of the improved tender underframe, and Fig. 2 is a longitudinal sectional view taken through the center of the underframe.

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

In the drawings, 1 indicates the longi- `tudinal members, 2 the transverse members,

3 the bolster members, 4 the front end sill, and 5 the rear end sill. Each of these end sills is rovided with an inwardly extending flange forming a strengthenin web and assets for the longitudinal mem ers. The front end sill is provided with a pocket 8 on its under side for receiving the pocketcoupler, the top Wall of said pocket being.

formed by the bottom flange of the dead block, while the bottom wall of said coupler is substantially a continuation of the bottom flange of the end sill. Due to the high location of this pocket coupler, the central longitudinal members have their bottom flanges deflected upwardly, as shown in Fig. 2, to meet and strengthen the walls of the ocket coupler.

T e centrally located transverse member 2 is strengthened by horizontally disposed flanges 9 and 10, the latter being formed integral with a box-like housin 11 open 0n its under side for accommodating parts of the water scoop by which Water may be taken from a trough and introduced into the tank when the locomotive is under way.

As illustrated immediately in front of the rear bolster, the draft sills are fitted for the reception of transom draft gear, which is,

in the-construction of the car, introduced from below. It will be noted that the flanges 1a of the draft members are normally directed inwardly from the webs throughout the length of said draft members. At the point lb where the draft gear is to be introduced, however, the lower flanges of the draft members are diverted from the inner sides of the webs to the outer side so that none, or a comparatively small projection 1c remains presented inwardly. This eon struction permits of the introducetion of the transom draft caring, While not weakening the draft mem ers at this point.

1.2 indicates the floor of the tender which is usually of wood, and projecting up through this floor is an abutment 13 slight-ly in advance of t-he central transverse member, the upper end of this abutment being curved rearwardly, as shown, so as to engage the nose of the tank 14 at the rear of the coal receptacle. In this manner the tank is anchored to the underframe. The ends of the end sill terminate short of the sides of the frame, so as to accommodate steps 15, shown in dotted lines, which steps are preferably bolted in position. The end sill eX- tends up above the plane of the longitudinal members of the car soaswto provide abutmcnts for the end Wall of the tank, and in addition the integral web 13 engages the nose of the tank at the rear of the coal bin so that the tank is not only held against longitudinal movement by the end sills, but is anchored to the underframe by the web 13, said web extending up into the coal bin and preventing lateral movement of the tank on the underframe.

A tender frame constructed as above described is exceedin ly simple and strong, and is not liable to fie 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:

1. In a cast steel underframe, the combination of holsters 1 ad longitudinal members integrally connected to said holsters, said lon itudinal members having flan es at their upper and low Vr edges on one sic e only throughout art of their length and on both sides throng iout part of their length.

2. In a cast steel underframe, the combination of bolsters and longitudinal members integral therewith, all of said parts being flanged, and the bottom flanges of said longitudinal members near the holsters being cut away.

3. In a cast steel underframe7 the combination of flanged longitudinal members having inwardly presented flanges throughout the greater portion of their length, and outwardly present-ed flanges at points adjacent the holsters.

4. In a cast steel underframe, the combination with bolster members, of longitudinal members flanged throughout their length, the bottom flanges adjacent the bolster being cut away and said members be-v signature in the presence of two witnesses, 20
