TENDER FRAME STRUCTURE Application filed. January 27, 1928.

This invention relates to improvements in tank car constructions and more particularly to tender frame and tank constructions, al-

though not limited to such use.

As heretofore tenders have been provided with cast steel main frames upon which the tank body is directly supported, and more recently such main frames have been more or less skeletonized so as to include only a centrally disposed longitudinal beam and transversely disposed bolsters and sills formed integral therewith, upon which the tank body is sup ported.

In carrying out my invention I provide an improved construction of tender frame and tank body of the skeletonized type above described, wherein a portion of the frame projects upwardly into the tank body and the bottom plates of the tank are connected directly to the sides of the frame members considerably below the top thereof, so that said frame members project into and form a part of the bottom of the tank. This construction therefore provides a simple and effective means of connecting and supporting the tender tank body on its frame, and also permitting the tender body to set lower on the frame with a reduced center of gravity.

Other features of advantage will appear from time to time as the description proceeds.

The invention may best be understood from the accompanying rawings, in which Figure 1 is a side view of a locomotive tender constructed in accordance with my invention.

Figure 2 is an enlarged fragmentary view of a rear portion of the tank and frame,

with a portion of the tank side broken awa Figure 3 is a fragmentary plan view of the rear end of the tender frame, with the upper half of said frame shown in horizontal section.

Figure 5 is a fragmentary vertical section taken on line 55 of Figure 3.

Figure 6 is a fragmentary vertical section 7 taken on line 66 of Figure 4:.

Figure 7 is a transverse section taken on line 77 of Figure 2, and I Figure 8 is a typical transverse section showingthe interior construction of the tank body taken on line 88 of Figure. 1. lteferring now to details shown in the drawings, the locomotive tender shown in Figure 1 comprises a tank 10, supported on main frame 11 which in turn issupported on trucks 12, 12, which may be of any suitable construction. The tank 10 shown here 1n is of the usual two-compartment type, the

rear compartment 10a being for water and the front compartment 10?) for coal.

The main frame 11 consists of a centrally disposed beam or sill 15 and laterally eX- tending bolsters 16 and 17, near the front and rear end thereof, and a rear end sill 18,

all preferably castintegral with each other.

end of the tank 10.

The bolsters 16 and 17 are also of a box girder type but as shown herein are rela-' tively wider than the center sill, and extend almost the full width of the tank body 10, as is best shown in Figures 3, 5 and 6. The top walls 20 of the bolsters are preferably in thesame plane as the top wall 21 of the central girder 15. The side walls 22, 22 and end walls 23 of the bolsters are substantially upright and have a horizontal flange or projection '25 along their lower margins, which joins with continuous flanges 26, 26 formed alongthe sidewalls 27 27 of.

the central beam 15.

The bottom walls 29 of the bolsters 16 and 17 are offset upwardly to form recessed porframe by riveting or Welding horizontally disposed. plates 35, 35 along the flanges 25 and 26 of the bolster and central beam respectively. With thls construction the upper portions of the bolsters and center frame form a part of the tank bottom, but project substantially above the bottom water line of the tank, as clearly shown in Figures 5, 6, 7 and 8. In the form shown, the bottom plate near the rear end of the tank rests upon the angular braces 19 and end sill 1S, and may be secured thereto in anysuitable manner, as by welding, riveting or bolting.

Details of construction of the superstructure comprising the tank 10 may vary Widely; for instance, in the cross section shown in Figure 8 said tank body is made up of two side walls 38, 38, riveted or welded to upstanding flanges 39, 39 formed inte- 'grally with the bottom plates 35, 35. A centhe sides of the tank.

I claim 1. In a tank car, a main frame comprising;

a longitudinal center sill, transversebolsters connected therewith, andtank bottom plates secured to said sill and bolstersina continuous line adjacent their lower edges, and extending laterally therefrom to form. with said sill and bolsters the bottom of a tank.

2. In a tank car, a main frame comprising a longitudinal center sill of box girder form, transverse bolsters connected therewith, flanges extending around said sill 'andbolsters in a continuous line adjacent their lower edges, and tank bottom platessecured to said flanges and extending laterally therefrom to form with said silland bolsters the bottom of a tank.

3. In a tank car, a main frame comprising a longitucinal center sill of box girder form, transverse bolsters connected therewith, flanges extending around said sill and bolsters in a continuous line adjacent their lower ed es, and tank bottom plates secured casting comprising a longitudinal center sill casting comprising a longitudinal center sill and transverse bolsters both of box girder construction, tank bottom plates secured to said center sill and bolsters in a continuous line adj acenttheir lower edges to form with said sill. and bolsters the bottom of a tank, said bolsters'being of less vertical height than said central sill, and having recessed portions on their under surfaces to afford clearance for their respective truck bolsters.
