.Apptcation lcd February 1, 1917. lSerial No. 1515,820.
To all 'whom t may'. concem` i Be it known that I, EDGAR PRICE, a
citizen of the United States,y resid-ing at Port` Chester, in the county of 4Westchester and State 'of N ew York, have invented certain new anduseful Improvements in Electricv Furnaces, of which the following is aspecification.
Thisinvention relates toelectriolfurnaces, Vthe primary object of the invention being to provide in-,connectionwith such furnaces a hear-th or bed which/will not be subject to rapid destruction by oxidation yor other influences'. In the particular embodiment ,ofthel invention choseny for illustration, the
hearth constitutes one of the furnace electrodes lor circuit terminals,lv but the Ainvention is not restricted touse in ,furnaces of this particular type. Y' The accompanying drawings represent an illustrative embodiment of the invention...
Figure 1 is avertidalseotional-view of a furnace constructed in' accordance with my invention; and
Fig..`2 is a horizontal section thereof on'- lines II-IIJof Fig. 'ha portion only of p the overlapping plates 1seing lshown in place upon the base Vof the flrfnace.-" i l Referring to thesailrA drawings, l represents the refractory wards of the furnace,4

be employed.
disposed upon the metal base 2, and preferably in direct contact therewith. I These are usually of sheet iron which may be of 3() gage or heavier, and are Ylaid in an overllapping or vshingle-like series, as clearly" shown in the figures. The usual carbon hearth 6 is laid upon these plates, comprising in the' particular construction illustrated a number of blocks or bricks of carbon or c arbonaceous material so disposed as .to breakjoints. Electrical connections may.
be made, as diagrammatically indicated at 7, to 'the base yand depending electrode, re-
spectivel In `electric furnaces of the type referred to herein it is essential that the base should `be adequately cooled; and this in turn renders it practically desirable to use a segr f mental/base .construction, in order to avoid the breaking which would 'otherwise be' liable to `occur under unequal heating and l temperature-changes. This ordinarily leads to a ratherfrapid destruction ofthe overlying carbon hearth, owing largely to oxidation by air and moisture entering from bef low. I have found however that a much longer life is assured to the hearth by profurnace the series of overlapping, relatively thin metal sheets or plates as above described.l These sheets are pressed into contact with each other by the weight of the l overlapping metal sheets interposed between said base and hearth.
2. In an electric furnace, the combination of `-a cast-metal base, a hearth or bed of carbonaceous material, and a series'of overlapping metal sheets interposed between said base and hearth.
3. In an electric furnace, the combination of. a segmental metal base, cooling means therefor, a hearth or bed, and a series of overlapping metal sheetsv interposed bei ltween said base and hearth. A number of metal sheets or plates 5 arennGAR'r. Pinon. IlVitnesses:
