BOTTOM-POUR LADLE.

Specification of Letters Patent. Patented Apr. 27', 192.0.

. Application led August 22, 1918. 'Serial No. 250,926.

To all 'whom it may concern: y Be it known that I, FRANK Comms, a c1t1- zen of the United States, residing at Pittsbur h, in the county of Allegheny and State of ennsylvania, have invented a new and useful Improvement inBottom-Pour Ladles, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification,- in. which: y Figure 1 is. a sectional view through a portion of a -bottom pour ladle and a stopper, showing one form of my invention.

Fig. 2 is a plan view of the nozzle, and

Fig. 3 is a sectional perspective view on the line III-III of Fig. 2.

`This invention relates to an improve= ment in bottom pour ladles, and is designed to provide a cheap and eilicent device whereby` the quantity .of metal passing through l'the pouring spout may be varied `and also to provide a spout. for pouring a' plurality of small streams without afectlng ment of theA jthe spirit an `fined in the appended claims.

the `volume of the liow, so that the gases can more readily escape from the metal durin the pouring. ,A

he precise nature ofvmyv invention will be understood by reference to the accompanying drawings, which will now be described,` it being premised, however, that various changes can be made in the details ofl construction and the' general 'arrange-v arts, without departing from d scope of my inventionas de- Referring to the drawings, the reference character 2 designates the body of the ladle which is provided with a refractory lining 3. 4 is the pouring spout or nozzle. mounted in the bottom of the ladle and. which is provided with a cylindrical recess 5 in the upper portion thereof.

with this recess and extending through the other end of the pouringrspoutl 4 are a. plurality of openings 6.- hese openings are outwardlyv Haring and are arranged lto di-v A {hdm-*into a.-

vide the metal flowing from plurality of streams of diameter. "7 designates the stopper whic of thezusual form ,for entering or closing the'rec'es's 5to stepstheflow "of metal through the nozzle. Y

th is 4wfell known to those faniliar with e art o pouring `an .particularly ingots, better castings dan be made if thestream of metal flowing to the mold is of small diameter,`as the gases within the metal can more readily escape from a small- Communicating Y stream than from a large stream. Heretoi fore attempts have been made to pour the castings by reducing the size of the opening in the nozzle inforder to permit the escapel of the gases, but this reduction in the vsize of the pouring opening has also `reduced the speed of the iow of metal. By my improved device, I am enabled to reduce [the size of the streams without affecting vthe speed of the flow of the metal. My nozzle is also very well adapted for pouring castings of different sizes, as all of the openings may be left open when pouring castings requiring a large volume of metal and one or more of the openings can be plugged up with clay when pouring smaller castings.

The advantages of my invention result from the provislon of a ladle having a plurality of pouring openings therethrough whlch are arranged to be closed with a single stopper.`

claim: 1. A bottom pour ladle having a removable refractory pouring spout therein, said spout having an annular flange adapted to be supported on a -seat inthe bottom of the their being a p urality of outwardly flaring openings communicating with said opening "and extending through the spout, substantially as described.

ladle, said 'spout having a cylindrical open- 3. vA bottom pour ladle comprising a removable refractoryv pouring spout, said spout, having la recess In its upper part adapted to be closed bymeans of a stopper, .and having a plurality of openings com municating with said recess and extending entirely'throu h said spout co-axially with saidrecess and adapted to form a plurality of small feedin openings for a common mo'ldsubstantia y as described.

I n testimony whereof I have hereunto set m hand.
