CARL 1. ASTROM, OF EAST ORANGE, NEW JERSEY, .ASSIGNOR TO M. H. TREADWELL COMPANY, OF NEW YORK, N. Y., A CORPORATION OF NEW YORK.

HOT-METAL GAR.

Application filed December 1, 1919.

T 0 all whom it may concern: 1 Be it known that I, CARL P. AsTRoM, a citizen of the United States, and resident of East Orange, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Hot-Metal lars, of which the following is a specification.

This invention relates to large dumping cars used for transporting hot metal from the furnace runners, and one of the objects of the invention is to construct the cars in large units, say of one hundred tons cap-ac ity, and to enable the use of the same without materially changing the runners which heretofore have ordinarily been designed for cars of smaller capacity.

Another object of the invention is to insure proper and complete drainage of the contents of these large cars in a minimum of time by having the interior inclined.

The novel features of construction, combinations and relations of parts which make possible the accomplishment of the foregoing objects will be described. in detail in the following specification, which is to be considered in conjunction with the accompanying drawing in which illustrations of difl'erent embodiments of the invention are given.

Figures 1 and 2 are side elevations of two different forms of the invention, the truck structure of the car in each instance being indicated as broken away.

As shown in Fig. 1 the closed car body is of generally truncated conical shape and the inclined interior chamber 9 therein for the hot metal is of substantially corresponding shape so that the walls of said cham- Specification of Letters Patent.

her are inclined with respect to the axis of the trunnions. This insures a drainage of the contents to one end of the chamber, that is, to the larger end or where the walls are farthest removed from the center of support.

Practically similar results are obtained with a shorter wheel base by the provision of a substantially cylindrical car body and hot metal chamber 10 having its axis inclined with respect to the axis of support, as indicated in Fig. 2.

As shown in the figures referred to, the pouring spout or opening 11 is in each instance located at one end of the chamber and at a point where the walls of the chamber are farthest removed from the pouring axis. This construction, it will be evident, provides a natural flow to the discharge outlet and enables the complete drainage of the chamber.

The location of the pouring spout at the end of the car serves a further useful purpose, in that it enables these large cars, which, for instance, may be each of one hundred tons capacity, to be used with runners which have been designed for cars of much smaller capacity. This is possible because of the fact that the cars can be made up in trains with the pouring spouts of adjacent cars placed in adjoining relation. This brings the pouring spouts relatively close together, and in position. where they will register with filling or pouring runners which have been spaced for smaller cars, or where small blast furnaces are close together. This is a distinct advantage, in that it enables cars of much larger capacity to be used with runners which, as before stated, have been designed for smaller cars, and does not require increased length of runners. Also, the cars may be used with runners which have been spaced the full distance for large capacity cars, in which event the train would be made up with the pouring spouts in like relation instead of in adjacent relation. For some irregular methods of spacing the trains may be made up with some of the spouts adjacent and others in like relation.

This invention makes large hot metal cars adaptable to a variety of uses and suitable for variously arranged furnaces and runners, and in each instance the proper drainage of the full contents is properly provided for.

What I claim is:

1. In a hot metal car, a tilting elongated car body having trunnions at its opposite ends and provided With a pouring spout located nearer to one end than to the other to thereby enable variable spacing between the pouring spouts by the placement of the cars in diflerent end to end relation in a train.

2. In hot metal cars, trucks and tilting elongated car bodies carried thereby and forming containers for the hot metal, each of said car bodies having a pouring opening located nearer to one end than to the other and thereby enabling dilferential spacing of the pouring openings by the location of the car bodies in different end to end relation in a train.

3. In a hot metal car, a tilting car body having trunnions at opposite ends and a spout adjacent one end thereof, and arranged With an inclined bottom and top that When dumped the residue of metal drains to the spout.

4c. In a hot metal car, a tilting car body provided with trunnions and having a hot metal-containing chamber provided with Walls inclined to the axis of the trunnions, said chamber having a pouring outlet disposed at one end of the chamber and substantially at a point in the chamber Where the Wall is farthest removed from the tilting CARL P.
