METAL-TRANSFER CAR.

Specification of Letters Patent.

Patented 1920.

To all whom it may concern:

Be it known that we, EDGAR J. REILLY and ALFRED C. NELSON, both citizens of the United States, residing at Youngstown, in the county of Mahoning and State of Ohio, and Lakewood, in the county of Cuyahoga and State of Ohio, respectively, have invented a new andus'eful Improvement in Metal-Transfer Cars, of which the following is a full, clear, and exact description, reference being bad to the accompanying drawings, forming part of this specification, inwhich- I Figure 1 is a side elevation of a transfer car embodying our invention, together with its pouring stand, the dumping position of the car being indicated in dotted lines.

Fig. 2 is a plan view of the same.

Fig. 3 is a front elevation of the car.

Fig. i is a detail view showing the means spout, and

Fig. 5 is a detail view illustrating the tilting pouring trough in. front elevation.

Our invention has relation to metal transfer cars, and more particularly to cars for use in foundry, blast furnace and steel works practice generally, and which are designed to receive a charge of hot metal from a charged ladle filled directly at the blast furnace, and transfer the metal to small ladles which distribute it throughout the foundry.

In the usual practice of foundries in which this system of handling hot metalis employed, the transfer car is usually constructed and arranged to receive its charge and also pour the charge at right angles to the track on which the said ladle runs.

Our present invention provides that a transfer car is arranged to pour its charge in a direction parallel to the track upon which it runs, and which may receive its charge either from the side of the track at right angles thereto, or from a direction parallel to the track." It provides a ladle of a character which can be readily handled and by which the charge can be continu ously'distributed to aplurality of small ladies in a" convenient and efficient manner.

Our, invention is also designed to provide a transf r car of this typ hich, s

closed to the maximum extent, all openings on the car being covered as tightly as possible in order to minimize heat losses.

The nature of our invention will be best understood by reference to the accompanying drawings in which we have shown a preferred embodiment thereof and which will now be described, it being premised, however, that various changes can be made in the detail of construction, arrangement and combination of parts, without departing from the spirit and scope of our invention asdefined in the appended claims.v

In these drawings the numeral 2 designates the frame of the transfer car which is of any suitable construction and which is mounted upon the wheels 3 adapted to run on the track rails 4. The metal container consists of a cylindrical body portion 5 closed at its rear end and having at its rear portion an upwardly projecting filling neck 6 having a top filling opening which is normally closed by a movable tight fitting cover 7. The forward portion 8 of the container is in the form of an upwardly extending delivery spout having a pouring opening at its upper end. This spout is of smaller diameter than the top of the container and projects obliquely upwardly therefrom. The frame of the car is provided at each side with open seats or supports 9, which are engaged by trunnions 10 on the container body, there be ing two of these trunnions at each side. The cover 7 is arranged to be moved longitudinally on the car to uncover the filling opening 11, and this may be effected in various ways. In the drawings we have shown this cover as arranged to slide upon the guides 12, and to be moved on 'such guides by means of a screw shaft 13 connected thereto and mountedin a suitable support 14 on the container body. This shaft is shown as being provided with a chain wheel 15 over which runs anendless chain 16, which extends to a position convenient for operation. Fig. 1 shows the cover in its closed position, while Fig. 2 shows it moved to the open position.

The pouring opening of the container is also normally closed, except for a small 1S hinged or pivoted at 19 and which is normally secured by suitable releasing devices 20, such as indicated in detail in Fig. 4;. This cover may be provided with a peep hole 21 for the purpose of looking into the ladle at any time, and which hole can be plugged at any time while the metal is being poured andthe ladle is raised for pourmg. I

The lower rear portion of the car is provided with a suitable lifting projection 22, which may be engaged by an over head crane for the purpose of tilting the container.

23. designates an operators cab on the forward end portion of the car frame at one side of the delivery spout. The car may be electrically propelled, a motor 24, controller 25 and trolley 27 being provided for this purpose.

The tap, or delivery opening 17, is designed, when the container is tilted in the manner hereinafter described, to deliver the molten metal into a trough or runner 28 having two pouring branches 29. This branched trough or runner is supported in any suitable manner, as upon the fulcrum 30 shown in Fig. 5, so that it may be tilted laterally to pour either to the right or left hand side through one or the other of the branches into a small distributing ladle 31. 32 designates a suitable lever by means of which the tilting may be effected. This trough is mounted on a pouring stand having two bearings 34- at opposite sides of the pouring spout for engagement with the forwardly extending projections 35 on the container.

The operation is as follows:The large ladle 36 (indicated in dot-dash lines in Fig. 1), which brings the hot metal from the furnace, is run up to the transfer car and is tipped in the usual manner to discharge into the filling opening 11, the cover 7' of which has been removed. When the container has been filled and the cover 7 reseated, an overhead crane, of well known type, is engaged with the lifting projection 22 and the entire container tilted upwardly and forwardly in a longitudinal direction to the position shown in dot-dash lines in Fig. 1.

The initial tilting movement may take place upon the forward trunnions 10, or the car may be moved forwardly so that the projection 35 will immediately engage the supports 34 of the pouring stand. The small ladles 31 are brought up in alternation from opposite sides so that the discharge from the transfer car may be continuous, the container being kept continuously raised during pouring.

he body portion 5 of the ladle and the forward portion 8, forming the pouring spout, are preferably made in separate sections having abutted bolting flanges 37. This permits of the container being readily 1. YA hot metal transfer device, comprising a support, and a container mounted on said support to tilt upwardly and forwardly in the direction of the longitudinal axis of the container, said container having a filling opening at its rear end, and a delivery opening at its forward end, substantially as described.

2. A hot metal transfer device, comprising a support and a container mounted on said support to tilt upwardly and forwardly in the direction of the longitudinal axis of the container, said container having a filling opening at its rear end portion and a removable closure for said opening, substantially as described.

opening at its forward end portion, and a movable cover partially closing said opening, substantially as described.

4. A transfer device for hot metal, comprising a car, a container'mounted on said car, said car and container having means whereby the container may be tilted upwardly and forwardly in a longitudinal direction, said container having a filling opening at its rear portion and a delivery opening at its forward portion, substantially as described. i

5. A hot metal transfer device, comprising a container having a cylindrical body provided with a filling opening at its rear portion and with an upwardly and forwardly extending delivery spout at its forward portion, together with a movable cover for the filling opening and a movable cover for partially closing the delivery opening of said spout, substantially as described.

6. In a hot metal transfer apparatus, the combination with a support and a hot metal container mounted thereon and having means which permits it to be tilted in a longitudinal direction, of a pouring stand adapted for cooperation with the container during its tilting movement, and a laterally tiltablebranched pouring trough or runner into which said container is arranged to dis charge, substantially as described.
