, To aZMqhbm-ttmay whcemL y it knownthatl, CHARLES E. WILSON, a c t-teen of the United States, residin at Hood R ver, county ofllood River, an State of 5 Ore on-, have.invented,a certain new and useful, gnprovenlent in Electric smelting-Fur naces,- 0f whlchithe following is a specificai w s r My-Jnvention relates to a new anduseful improvement i-naelectric smelting furnaces A generallyand more particularly to such furnaces as aretused for the reduction of term titanium in steel-foundries and has for its ob ect to. rovide, an exceedmgly simple and evice 1 of this character in ,which the air-would be prevented from entering the crucible. With these-ends in" view, this invention consists in the details of construction and combination :of elements hereihafter set forth andjthen specifically desi ated by the clain'is.
l In o1der-that those s ledlifi the art to which this; invention a. pertains may understand how to make an use the same, I will "describe its construction in detail, referring bywletter toi--the accompanying drawln forming a art of this Specification, in whi thefigurennthedra'wing 1s a view partly in section and partly in elevation.
rovide a beef any desired shape or size which isbui t of chrome bricks B and carbon C, and around these placed-- a metallic plate D. The
4 sides ofthe crucible are built on'an an le so I "tgt'the -lower portion of said cruci le is aller'than then: per, and'leading from the vlowerIpiortiOm-t ereof is an opening E abouttthe outer-end of which is placed a 4g chute F leading to the *latlle (it.
'OnTBGp of the crucible is placed a suitable wittel cooled' jacket H through which are formed suitabldopemngs I to allow the electrodesto pass in the crucible A as will be hereinafter described. Throu hyone ed e is formed another hole'J in-whidh isfitte the valve K against which resents valve L. Between the openings I is formed another opening M intowhich leads the screw conveyer N above which is secured a holpper O 1 into which may be placed the materia which the conveyer is to carry into the crucible A.
P indicates tubes bolted to the water cooled jacket above the openings I and formed with carried to the foundry. It is advisable to the upper ends are the flangesQ and about these tubes P are piacedthej tljbQSLH haying inwardly extendin flanges is whiclf-enga with the flanges formed onlthe tu'bes I These flanges S are adaptefistefit over-chase against the outside ofthe tubesiFP so-zisito prevent any air fromenteringi 'said tahcsand insulating material P issf aced betweemthe tubes P and the jacket vin-orderstoprevent the. short circuitirng the ciirrent. The electrodes T are adapted-d c pass throu h these tubes into the crucibleu-A amtlare'he' d securely to the 11 per tubes-R b ,itl'a'e ri'n'ggU which is clampet aroundtheie ectrpdes'ta'nd secured together by the bolts fUT Ofitlie lower part of these rin s-aieifortned flanges V by means of which t eyn-maybe-claniped to the tube R b the bolts-V.
