HOT METAL DUMPING CAR. APPLICATIION HLED MAR. 27, I920.
UNITED STATES PATENT OFFICE.
CARL P. ASTROM, OF EAST ORANGE, NEW JERSEY, ASSIGNOR TO M. H. TREADWELL COMPANY, A CORPORATION OF NEW YORK.
HOT-METAL-DUMPING CAR.
Application filed March 27,
To all whom it may concern Be it known that I, CARL P. As'rRoM, 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- Dumping Cars, of which the following is a specification.
This invention relates to hot metal dumping cars and has for its object to provide a car especially adapted for conveying large quantities of hot metal, the design herein shown being for an apparatus capable of carrying upward of ninety-five tons of hot metal at a time.
The present tendency in the art is to provide cars of this type with as large capacity as possible, because of reduction of heat losses and also convenience in handling.
Although a car of this type is practicable without any underframe, some regulations of the Interstate Commerce Commission require an underframe, especialy where there is a four or'more wheeled truck at each end.
In building a car of such capacity, with the necessary compliance with M. C. B. standards, and also to come Within the permissible standard'railroad clearance, the length becomes such as to necessitate provision for expansion and contraction. of the car body relativeto the underframe.
According to this invention a car of this type is provided wherein this expansion and contraction of the car body is taken care of either by connecting the underfranie with one end in such way as to permit expansion and contraction, as by a standard type of friction draft rigging, or one end of the car body is connected with its supporting pedestal so as to permit the necessary expansion and contraction.
The invention will be described with reference to both forms in the accompanying drawings, wherein Figure 1 is an elevation, partly in section, of a car body embodying the invention;
Fig. 2 is an end detailed view; and
Fig. 3 is a detailed view of a modification.
Although the invention is applicable to a car having a rigid platform or underframe carrying the car body, and to various numbers of wheels, the common practice is to provide a hot metal car of this character Specification of Letters Patent.

1920. Serial No. 369,212.
with a dumping body supported at each end on trunnions carried by end'platforms, and the end platforms supported on trucks. The underframe extends from one platform to the other with a flexible connection at one end to permit the variation in length of the car body due to its temperature, or else the underframe will be. rigidly connected between the platforms and flexible connection inserted between one end of the car body and its supports.
Referring to Fig. l: 1 represents a track on which run the trucks 2, each carrying a platform 3 supported at the center by spherical bearing 4, and at the sides against tilting bythe usual side bearings These may each consist of a trough in the side frame of the truck carrying a roller, and a pad-on the underside of the platform bearing on the roller after the car has tilted sufficiently. 6 represents the car body CO11- sisting of a central cylindrical portion havingthe usual filling and pouring spout at the top with conical end portions, the latter carrying trunnions 7. At one end dumping gear, for either hand or power or both. may be provided, such as 8, and not necessary to be described. As shown in Fig. each trunnion carries two bearings c crating with pedestals 9, 10, the bearnr being shown in section at the right end of Fig. 1, so as to take end thrust as well as the load, the total mass of the car bodv whenloaded being such as to require it to be very firmly held against longitudinal strains. The pedestals 9 are positioned. directly over the spherical bearings 4:. 11 represents the underframe which is connected at one end to pedestal 9 as by bolts 12, and at the other end is inserted into a pocket 13 formed in the platform. In this pocket are provided curved thrust blocks 15 at each end, bearing against the shoulders 16, and between the thrust blocks 15 are alternately springs 17, convex blocks 18, and concave blocks 19. These are all tied to gether by a strap 20, carried by the end of the underframe 11. These parts are so assembled that the blocks 15 are under initial pressure and thereby held by the expansive force of the springs against the shoulders 16. When the car body expands or contracts, the distance will thus be taken up in this mechanism so that the underframe will always remain slidably and resiliently held in the pocket 13, while the springs will yield or expand sufficiently to prevent buckling or other damage either to the car body or to the trunnions.
Each platform 3 is further provided with the usual friction draft gear, similar to the parts just described, or other type of shock absorbing draft gear.
In Fig. the underfraine will be rigidly connected to the platforms at each end and one of the trunnions 7, preferably the one opposite the dumping gear will be provided with the same mechanism before described. also the trunnion at this end, of course, will not have thrust bearings at the pedestals, since the trunnion will have to slide in the bearings according to the variations in length of the car body. The trunnions at the other end will have the same thrust bearings as before described so as to hold the car body against longitudinal displacement. Between the blocks 15 and the shoulders 16, it will be ofadvantage to place ball or roller bearings 21, so as to permit easy dumping of the body.
Instead of the particular form of friction draft gear herein illustrated to be combined for the purpose of permitting relative expansion and contraction of the car body, and the underframe, other well known forms of draft gears or other equivalent mechanisms can be employed. It will be observed that the longitudinal movement permitted will compensate for variations of the car body and by reason of the springs being under initial tension the opposing thrusts due to the shoulders 16 will hold the car body in proper position. 7
Various modifications and changes may be made in the specific details herein described without departing from the scope of the appended claims.
What I claim is:
1. A hot metal dumping car comprising trucks carrying an elongated car body, an underframe connected between the trucks and means allowing a variation in distance between the trucks permitting expansion and contraction of the car body.
2. A hot metal dumping car comprising trucks carrying an elongated car body, an underframe connected between the trucks, and means comprising a resilient connection between the underframe and one of the trucks allowing a variation in distance between the trucks permitting expansion and contraction of the car body.
3. A hot metal dumping car comprising trucks, an elongated car body supported on horizontal pivots 9n the trucks so as to be tiltable, an underframe connected between the trucks, and means permitting expansion and contraction of the car body.
at. A hot metal dumping car comprising trucks, an elongated car body supported on horizontal pivots on the trucks so as to be tiltable, an underframe connected between the trucks and resilient means permitting expansion and contraction of the car body.
5., A hot metal dumping car comprising trucks, a platform swiveled on each truck, a plurality of journals mounted on each platform, an elongated car body formed with trunnions on each end, said trunnions supported by the said journals and an underframe connected between the platforms and means permitting expansion and contraction of the car body.
. 6. A hot metal dumping car comprising trucks, a platform swiveled on each truck, a plurality of journals mounted on each platform, a car body having end trunnions mounted in said journals, the journal nearest the car body on each truck being directly over the swivel of the platform, and underframe connected between the platforms and means permitting expansion and contrac tion of the car body.
7. A hot metal dumping car comprising trucks, a platform swiveled on each truck,
, a plurality of journals mounted on each platform, a car body having end trunnions mounted in said journals, the journal nearest the car body on each truck being directly over the swivel of the platform, and an underframe connected between the platforms. Sioned at New York city in the county of New York and State of New York.
