HOT-METAL CAR.

Application led May 13, 1920. Serial No. 381,057.

To all 'whom t may concern.'

Be it known that we, ALFRED C. NELSON and EDGAR J. REILLY, both citizens of the United States, residing respectively at Lakewood, county of Cuyahoga, and State of Ohio, and Youngstown. county of Mahoning, and State of Ohio. have invented a new and useful Improvement in Hot-Metal Cars, of which the following is a full, clear, and exact description.

The present invention relates broadly to cars or carriers for molten metal or other materials, and more particularly to cars intended for hot metal, cinders and the like.

An important object of the present invention is to provide a compactly designed car having both increased capacity and strength.

Another object of the present invention is to provide a car of the character described having a mounting from which it is readily removable.

Still another object of the invention is to provide a support comprising a pair of spaced trucks connected by a longitudinally extending center sill or brace whereby the trucks are maintained in predetermined spaced position when the container is removed therefrom.

A further object of the invention is to provide the trucks with anti-friction bearings on which the container may be rotated and which are adapted to prevent endwise movement of the container during rotation.

The foregoing and other objects. together with their attendant advantages, will be apparent as the invention becomes better understood hy reference to the accompanying specification and drawings forming a part thereof, it being premised that changes may be made in the various details and the manner of operation within the scope of the appended claims without departing from the spirit of the invention.

Figure 1 is a side elevation of a portion of our improved hot metal car:

Figure 2 is a plan view partly broken away of one form of the container;

Figure 3 is an end view of the construction illustrated in Figure l;

Figure 4 is an end view, partly broken away, of the opposite end of the hot metal oar;

Figure 5 is a cross sectional View through the form of the car illustrated in Figure 1; and

Figure 6 is a similar View through a slightly modified form of car.

This invention provides aV carrier of large capacity, for distributing hot metal from a blast furnace to the required point of disposition about steel works or foundries, such as mixers, pig casting machines, moulds, etc.

It isy desirable that a carrier for use in transporting hot metal, cinders and the like, be constructed as compactly as possible without interfering with the strength or capacity thereof. As these carriers are frequently adapted for receiving and transporting as high as seventy-tive or more tons of material at a time, the importance of these features will be apparent. At the same time, it is desirable to provide a simple mounting for the container which may permit rotation thereof while functioning as a supplemental tie between the spaced trucks. and prevent-4 ing accidental longitudinal movement of the container.

Not only does the container rotate on the trucks as described. but it is of suoli design that it can be equipped with lifting lugs so it can be raised while full of metal and lifted to any desirable receiving receptacle, such as a mixer, etc., without requiring any disconnection of any parts. The container, when emptied, may then be returned to its proper position on the car body without requiring any connection of parts.

ve have found that all of these desirable features may be produced by constructing a container which is oval or elliptical in longitudinal section as described hereinafter.

Referring more particularly to the drawings. there is illustrated in Figure 1 a hot metal car construction comprising spaced trucks 1 and 2 which may be of any desired construction. Extending rearwardl from each of the truck frames is a projection 3 to which are secured the opposite ends of the longitudinally extending center sill or brace 4. This center sill serves to effectively tie the trucks together to always maintain the same in proper spaced relation for the reception of a hot metal container. At the same time, by reason of its central location, this sill is entirely out ofthe way and permits the operation of the hot metal car as desired.

The container in its preferred embodiment comprises a main body portion 5 whichl may consist of a suitable refractory lining 6 and an outer enclosing metal shell or casing 7. In order to provide a construction having a maximum strength and capacity, the body of the container may be formed either as an ovoid or ellipsoid of revolution. Such a shape provides a container which is curved or arched in every section, thereby insuring a maximum strength. This shape also facilitates discharging the container as the contents thereof readily follow the contour of the refractory lining.

Secured to each end of the container 5 is a trunnion 8. These trunnions are each provided with a concave surface 9 adapted to receive the ends of the container 5 and partially embrace the same. If desired, the entire structure may be reinforced by employing metallic braces 10 eXtendin between the trunnions. The outer en of each of the trunnions are preferably cylindrical in shape and are formed with an enlarged cylindrical flange 11. These flanges are adapted to co-operate by gravity with anti-friction bearings 12, suitably mounted on each of the trucks 1 and 2 as clearly shown in Figures 1 and 4. aoh of the bearings ma comprise a series of flanged rollers, the anges on the rollers co-operating with the enlargement 11 on the trunnions 8 for preventing longitudinal movement of the container and at the same time functioning as a. tie between the trucks supplementing the action of the center sill 4.

In the form of container illustrated in the first five figures of the drawings, there is provided an oval' discharge opening 13 extending substantially the entire width of the container and provided wit-h oppositely disposed pouring lips 14. For rotating the container to permit discharge of material over either of the pouring lips, there may be provided a motor 15, on the truck 1, for driving any suitable type of reduction gearing 16 intermediate the motor and container. This reduction gearing may mesh with a large gear 17 secured to one of the tran= nions 8, the point of engagement with the gear 17 being below the axis of rotation of the container, as clearly shown in Figure 3.

In some instances it has been found desirable to construct the container with a plurality of independent pouring openings 18, as shown in Figure 6. In such cases, each of the pouring openings will be provided with a suitable lip 19 over which the material may be discharged.

Due to the particular location of the center sill 4, and the sha e of the container 5, the container may e rotated from its upright position throughout more than 9()O in elther direction, thereby permitting a complete discharge of the contents of the container. This dumping position is illustrated in dotted lines in Figure 3 of the drawings. If side sills were employed for connecting the trucks, such a dumping operation could not be obtained and if the connecting sills are entirely eliminated the trucks will be capable of independent relative movement when the container is removed therefrom, thereby preventing expeditious replacing of the container in the anti-friction bearings provided.

One end of the. motor shaft may be provided with a suitable brake drum 15' by means of which the container can be held in upright position during transportation thereof, or by means of which the rotation of the container may be checked.

The advantages of the present.invention arise from the oval or elliptical shape of the container which permits ready mounting of the same by the use of trunnions as described.

Further advantages of the invention arise from the use of a center sill for tying the trucks in predetermined `spaced relation.

Still further advantages arise from the construction permitting rotation of the container andremoval thereof from the supporting trucks without necessitating anv manual operations of connecting and disconnecting.
