LOCOMOTIVE TENDER.

Application filed November 9, 1927.

My invention relates to certain improvements in locomotive tenders having a cast metal bottom section.

The object of this invention is to prov de a comparatively light integral casting which will form the bottom of the tank at the longitudinal centre, the casting being provided with lateral arms to which the sheet metal bottom plates are secured and to which also the transverse bafi'les are secured.

The invention relates to other details which will be fully described hereinafter.

In the accompanying drawings:

Fig. 1 is a sectional plan view, on the line 11, of Fig. 3, of the locomotive tender made in accordance with my invention;

Fig. 2 is a plan view of the cast metal bottom frame;

Fig. 3 is a longitudinal sectional view on the line 33, Fig. 1;

Fig. 4 is a transverse sectional view on the line 44, Fig. 3;

Fig. 5 is a transverse sectional View on the line 55, Fig. 3; and

Fig. 6v is a sectional view on the line 6-6, Fig. 5.

1 is the bottom frame of the tender, the frame extending the full length of the tender in the present instance. At each end of the tender are bumpers 2, which are preferably the full width of the tender, and cast integral with the frame is a coupling head 3, which may be made in any suitable manner without departing from the essential features of the invention.

4 is the base plate of the frame, and 5 is an upper plate, the upper plate being less in width than the base plate, the projecting portions of the base plate forming longitudinal flanges 16. The two plates are connected by longitudinal webs 6. The plates extend from one end of the frame to the other as clearly shown in the drawings. The bottom plate is solid.

At the water section a of the tender the upper plate has a series of perforations 7, and the webs 6 are perforated at 8, so that water can freely circulate in the space between the two plates.

Below the plate 4 is a box-shaped girder Serial No. 232,106.

9, which is cast integral with the frame, and on this girder are centre bearings 10 which rest in suitable bearings on the tender trucks (not shown).

On the frame are side bearing feet 11, which rest on suitable bearing plates carried by the structure.

Projecting laterally from the frame are a series of arms 1212 spaced a given distance apart. The arms 12 are connected by webs 13 and are located the forward end of the frame. The arms and webs support the bottom plates on each side of the fuel section b of the tender. Each of the arms 1212 has a vertical rib 12 to which the lateral transverse dash plates 14 and 15 are attached, preferably by welding as shown in Fig. 6.

The sheet metal bottom plates 15 which are located at each side of the frame are se cured to the frame by welding them to the longitudinal flange 16 and to the arms 12. In the present instance the outer edges of the plates 15 are bent upwards and are welded at 03 to the side plates 17 of the tender as clearly shown in Figs. 4 and 5, although in some instances the side plates may be bent under the arms and secured to the frame.

Projecting from the frame at the fuel sec tion are longitudinal ribs 18 and a transverse rib 19, which are offset to form a shoulder on which rest the side plates 20 and end plate 21, separating the fuel section from the water compartments at each side and at the rear end of the fuel section.

The plates 20 and 21 are flared as shown at 20 and 21*, respectively, to provide inclined side walls for the fuel section. The side plates are braced by the dash plates 14-14which are attached to the arms 12 and to the side plates 17 of the tender, while the end plate is braced by a longitudinal plate 22 extending from the bottom frame to the inclined section 21 of the plate 21, providing a very rigid construction.

At the forward end of the tender are headers 23 which close the water chamber at the forward end, while at the rear is a header 24. Extending longitudinally in the water section a are stiflening or dash plates 25, which are connected to the dash plates 15, which in turn are connected to the side plates of the tender and to the arms 12. Other dash plates 15 extend vertically and are narrow as illustrated in Fig. 1. All of these plates are secured to the top plate 26 of the water section which extends the full width of the tender and from the rear header 24 to the inclined portion 21" of the plate 21. This construction makes a very rigid tender and a comparatively light one, owing to the fact that the greater part of the weight of the bottom plate is at the centre of the structure of the tender, and that the arms are of sufficient weight to carry the load and to reinforce the structure.

I claim:

1. The combination in a locomotive tender, of a cast metal bottom section extending from end to end of the tender and forming the main support for the tender, said bottom section having lateral arms; sheet metal bottom plates extending under the arms at each side of the tender and secured to the frame; and side plates forming the sides of the tender.

2. The combination in a locomotive tender, of a longitudinally centrally arranged casting having lateral arms provided with vertical ribs; transverse dash plates secured to the ribs; sheet metal bottom plates extending under the arms and secured thereto; and side plates forming the sides of the tender to which the dash plates are also secured.

3. The combination in a locomotive tender, of a bottom section made in a single casting extending from end to end of the tender and having lateral arms spaced apart throughout its length and to which sheet metal bottom plates can be secured; and longitudinal members at the forward end of the tender connected by transverse members to which the plates which divide the fuel section from the water section are secured.

4. A bottom frame for a locomotive tender made in a single casting extending from end to end of the tender, said frame having bumpers at each end, and having laterally extending arms spaced apart to which the sheet metal bottom sections of the tender can be secured, said frame having upper and lower plates and a longitudinal girder depending from the lower plate.

5. A bottom frame for a locomotive tender made in a single casting extending from end to end of the tender, said frame having bumpers at each end, and having laterally extending arms spaced apart to which the sheet metal bottom sections of the tender can be secured, and to which transverse dash plates can be secured, said frame having upper and lower plates and a longitudinal girder depending from the lower plate.

6. In a tender, a bottom frame so formed that a part of said frame is within the water space of the tender, said frame having transverse ribs at the arms projecting into the tender and to which transverse dash plates can be secured.
