METAL-POITRINE' APPARATUS.

My invention relates to a metal pouring apparatus and while primarily intended for use in connection with the casting of steel ingot's,

it will be obvious that the device may be employed for any other purposes wherein it 'is found to be applicable.

Important objects ofthe invention are to provide a pouring apparatus of the character described which will permit of the emptying of the complete ladle load in one continuous flow without interruption; which embodies a cinder spout for conveying the cinder matter after the steel pouring operation without suspending the flow thereof; and

which is vertically adjustable to position same to best meet conditions found in practice; under such conditions facilitating and expediting the.inetal pouring operation.

Further objects of the invention are to provide a device of the class stated which is .sim-

ple in its construction and arrangement, strong, durable and efcient in its use, and comparatively inexpensive to manufacture,

install and operate.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement ofvparts and in the details of construction hereinafter de-l scribed and set forth, it being understood that changes in the precise embodiment of the invention hereinafter disclosed can be` made within the scope of what is claimed'without departing from the spirit.l of the invention.

In the drawing wherein likev numerals of reference designate corresponding parts throughout the several views Figure 1 is a side elevational view of a metal pouring apparatus constructed in accordance with the invention, and illustrating its adaptation with associated elements.

Figure 2 is a top plan view of the device.

Referring in detail to the drawing 1 denotes a ladle of the usual construction and as coinmonly employed for conveying the molten metal from the heating furnace'to the ingot molds 2. The latter are mounted on buggies 3 which travel on respective rail tracks indicated at 4 and 5, in the ordinary manner.

My improved pouring apparatus is disposed between the rail tracks 4 and 5, and comprises a. body portion A which includes arefractory lining 6 and is formed to pro.- vide a duplex-pouring trough 7 and a cinder spout 8.

The pouring trough 7 is p air of longitudinally aligne pockets, respectively indicated at 9 and 10, which are separated from each other by the elevated intermediate portion 11. The to of the latter is disposed below the even p ane of the top of the trough 7 to prevent the escape of the flowing metal when the pouring operation is transferred from one pocket to the other, in the manner and for the purpose to be described.

The bottom of each of the

trough pockets

9 and 10 is formed with a centrally disposed opening 12. The disposition of the respective openings l2 in the

trough pockets

9 and 10 is lsuch that the mold 2, carried by the buggy 3 on the track rails 4, is disposedin vertical alignment with the openinor 12 in the trough pocket 9, and that the mold:` 2 carried by the buggy 3 on the track rails 5 is disposed in vertical alignment with the opening 12 in the trough pocket 10. By this arrangement the metalilowin from either of the

pockets

9 and 10 will ow into the molds 2..

The cinder spout 8 extends along one side and projects beyond one end of the pouring trough 7. The cinder spout 8 is inclined so that the cinder matter will travel thereon by gravity. The projecting lower end of the cinder spout 8 is so disposed that cinder matter flowing therefrom will be caught by a. cinder buggy 13 mounted on rail track 14 provided therefor.

The body portion A is vertically adjustable to dispose the same to a position to best meet conditions found in practice7 preferably by means of a hydraulic structure which inclincs a plunger 15 and cylinder 16. The body portion A is fixed to the upper end of the plunger 15 and shifts with the lat-ter when .moving to the desired adjusted position.

The adjustment of the body portion A, in the manner stated, permits of the proper posi- (provided with a tioning ofthe body portion A relatively to varying heights of the molds into which the Vmetal is to be run.

A burner member l17 extends through each end of the pouring trough 7 into

respective pockets

9 and 10. The burner members 17 are provided for the purpose of keeping the pockets 9 and 1(1.intensely heated for maintaining the molten metal at the proper molding consistency. l Fuel' is supplied to the burner members 17 through a fuel supply pipe 18 'which includes a lazy-tongs pipe structure 19 compensating for the vertical ad- ]'ustmentsof the body portion A in the manner herein stated.

The ladle 1 embodies the usual pouring nozzle 20 provided with a closure plug 21. The latter is removed from the pouring nozzle 2O by a detachable rod 22, as clearly illustrated in Figure 1. Vhilethe construction of the ladle 1 and of the associated parts, in no way directly concern the present invention, the closure plug 21 and removing rod 22 therefore are herein'shown and described "to bring out the relative simplicity of these elements as compared to the' costly closure devices commonly employed for this purpose. In the use of my improved pouring a paratus the closure 21 is simply removed rom the pouring nozzle 2O and need not be replaced in the latter at any time during the metal pouring operation. At the present time, the lower end of the closure element employed is constantly immersed in the molten metal within the ladle 1 to suspend the flow of the metal therefrom while changing the position of the ladle 1 to fill the various molds. Such constant immersion of the lower end of the closure element causes the rapid disintegration of the same necessitating its replacement for each pouring operation of the ladle contents.

In practice, the operation of the present invention is'as follows The closure plug 21 is removed from the pouring nozzle 20, and assuming that the ladle 1 is in the position shown in Figure 1, the molten metal will How from the ladle 1 `into the trough .pocket 9 and through the opening 12 in the latter, into the mold 2, which is carried by the buggy 3 on the rail track 4. As soon as the mold is filled, the ladle 1 is shifted so that the metal will flow therefrom into the trough pocket 10 and through the opening 12 in the latter, into thenmold 2 which is carried by the buggy 3 on the rail track 5. During the filling operation of this last mold the previously filled mold is moved along the rail track 4 and replaced by a subsequent empty mold which receives the metal when the second mold has been filled. By providing suflicient molds to receive the contents of the ladle 1 in the manner stated, the pouring operation is continuous.

When the metal has been run from theladle 1 the latter is shifted so that the cinder matter remaining therein will flow into the cinder spout 8 to be conveyed to the cinder buggy 134 on the rail track 14.

The use of'my improved pouring apparatus will greatly facilitate and expedite the metal pouring operations, and provide for the economic manufacture of metal by its use.

What I claim is:

1. A metal pouring apparatus of the character described comprising a body portion provided with a plurality of pockets, each of said pockets having an opening formed in the bottom thereof, and burner elements carried by said body portion for heating said pockets.

2. A metal pouring apparatus of the character described comprising a body portion provided with a pair of pockets having an elevated portion disposed therebetween, the

top of said elevated portion being below the' even plane of the top of said body portion, the bottom of each of said pair of pockets formed with an opening, and burner elements carried by said body portion for heating said pockets.
