LIQUID-METAL-CI-IARGING CAB, FOB. OPEN-HEARTH FUR/HACES.

Application liled February 23, 1918.

.To all whom it may concern Be it known that we, CHARLES W. MCCLURE and EDGAR J. REILLY, Vboth citizens of the United States, residing at Youngstown, in the county of Mahoning and State of Ohio, have invented a new and useful Improvement in Liquid-Metal- Charging Cars for Open-Hearth Furnaces, of which the following isa full, clear, and exact description, reference beinghad to the accompanying drawings, forming part of this specification, in which:

Figure 1 is a side View of a charging car embodying our invention, and

Fig. 2 is an end elevation, with certain of the parts in section.

Our invention is designed to provide an improved apparatus for transferring and charging liquid metal into open hearth furnaces.

Generally considered, our invention comprises a body mounted to move on track rails adjacent to the charging door of the furnaces with which the apparatus is to be used; and a top pouring4 ladle tiltably mounted on the body, pouring means mounted on the body for tilting said ladle; and a spout mounted for transverse movement on the car in a position to receive the metal poured from the ladle, and arranged to be moved transversely to project its delivery end through the chargingdoor of a furnace. t

Our present invention is also designed to provide power means of simple and effective character for actuating thisftrough or Y spout.

Referring to the accompanying drawings inwhich we have shown the preferred embodiment of our invention and which will now be described, the numeral 2 designates the body of the charging car mounted on the track rails 3. 4L is the ladle having trunnions 5 located at the .upper portion thereof adjacent to its pouring spout or lip 6 and which engage suitable bearings 7 in the posts or brackets 8 fiXed to the frame of the body 2. The ladle is further supported by the brackets 9 secured thereto and which, when thefladle is in its normal horizontal position, rest upon the car, as indicated.

The ladle may be tilted to discharge its contents by any suitable mechanism.

In the drawings we have shownan electric motor 10 mounted on through a train of reduction gearing 11, drives a winding drum shaft 12. Connected to the winding drum 13 on this shaft the car which,

are chains 14 which pass upwardly and over tor 10 is operated the chains 141 will be actu-- ated `to tip the ladle from the position shown in full lines in Fig. 1 to the position shown in dotted lines in said figure. l/Vhen the ladle is tipped to this position the metal therein trough or spout 18 which is mounted in an inclined position transversely of the car 2 upon the truck wheels 19 which travel on the track 20. rlihe end portions of this track are bent upwardly, as indicated at 21, to form stops for limiting the travel of both wheels ,in both direction-s. j

In accordance with our present invention we mount upon the car another electric motor 22 which is connected to a train of reduction gearing 23 with a Winding drum 24. 25 is a flexible connection, such as a rope or cable, which isl connected at one end to the spout or trough 18 and extends thence forwardly and around an idler pulley or sheave 26 mounted on the car body 2; and thence rearwardly to the winding drum 24 to which its other end is connected. 27 designates a second flexible connection attached at one end to the intermediate portion of the spout 18 and extending thence to the winding drum 24 to which its other end is attached.

In operation,` after the ladle 4C receives a supply ofvliquid metal, the car is moved along the track rails 3 to a position adjacent to the furnaces to be charged. The motor 22 is operated in a direction to pull on the rope or cable 25 and thereby move the spout or trough 18 from the position shown in full lines in Fig. 2 to the position shown in dotted lines in said gure. When in this dotted line position, the delivery end is discharged into a of the spout or trough is moved through the door of the furnace to be charged. The ladle 4 is then tipped and emptied into said trough which delivers the liquid metal into the furnace.

After the charging operation is completed the motor 22 is reversed thereby pulling on the cable 27 and slacking the cable Q5. This draws the spout back to its normal position.

lt will be noted that the entire operation can be carried out without the use of a crane or a separate charging` machine and that it can be made to serve a number of open hearth furnaces built in line with each other. Y

It will also be noted that the pouring lip Vof'tjhe ladle is located substantially on the line, of the of its trunnioiis. This gives a short or low pour, the fall of metal being confined to the short drop between thev pouring lipV and the trough.; This eliminates the loss of metal by splashing which is ordinarily suffered when the longer drop of the old Amethod is @Jfllhloyed. f

The. ,entire apparatus is Simple in ts C011- struction and can be operated much more Conveniently than .can the apparatus Ordinarily employed, wherein a ladle car is used which is arranged to eater the Oren-hearth building at one end thereof for a short distance, together with a charging machine movable in front of the charging doors of the furnace, a charging spout arranged to be picked up. by `the charging machine and carried to and projected into the open charging door of the furnace t0 be charged, and a crane which can be Voperated to remove the ladle from the ladle car and carry it to ,pouring position with respect to the charging spout. This crane then tilts the ladle and discharges the metal into the charging spout and thence into the furnace.

The presentapplication is in part a continuation of our application Serial No.

We claim: 1,. A liquid metal charging car for openhearth furnaces, comprising a car adapted to be movedladjacent to thecharging door ofthe furnace, a ladle tiltably mounted on the car, a transversely arranged spout or trough arranged 4to receive the metal from the ladle, and means for moving said spout or troughtransversely of the car to. project its delivery end into charging relation to the furnace, substantially as described.
