ORE REDUCING AND REFINING FURNACE.

To all whom rit may concern.'

Be it known that I, HENRY L. CHARLES, a citizen of the United States, residing at Butte, in the county of Silver Bow and State My invention relates to improvements in ore reducing or refining furnaces and has for one of its principal objects to provide means for bracing the roof of the furnace without the' use of buck-stays, rods and similar devices heretofore generally employed. My invention also contemplates means for protecting that part of the furnace where the ore is admitted and various other features hereinafter more particularly set forth.

In the accompanying drawings I have illustrated in Figure 1 in vertical cross-section with parts broken away a suitable application of my invention. Fig. 2 is a longi- -tudinal section onA the line 2-2 of Fig. 1, with parts broken away, and Fig. 3 is a plan view onthe line 3 3 of Fig. 1, parts being broken away, the monolithic material not being shown.

4 indicates a suitable foundation, and 5--6 side walls of the furnace. v6 indicates the side wall of the next furnace arranged parallel in the usual manner. According to a preferred embodiment of my invention, the foundation 4L is preferably continued upwardly between the `walls 5-6 ofadjacent furnaces forming an abutment wall 7 as shown, thereby providing a suitable platform such as 8 for the convenient operation of the furnaces. This abutment Wall 7 may be suitably reinforced by steel girders Suc-h as S) and is preferably provided at opposite sides with recesses or pockets 10 into` which the ends of the bolts 11 may project, said bolts having| heads 12 adapted to engage the plates 13of suitable Water cooling sections or boxes hereinafter more fully referred to.

The plates 13 are in turn reinforced or braced by the webs of steel 14 which in turn bear against the walls of the water circulating chambers 15 as shown.

The roof of the furnace preferably consists of a double row of bricks 16-17 topped Specification of Letters Patent.

with a suitable covering of monolithic material or other suitable refractory material 34. The water circulating chambers 15 are preferably secured upon the outer margins of .thelower row of bricks and the lupper l layer of bricks and monolithic material preferably extend between the same as shown. These water'circula-ting boxes are preferably provided with an interior passage 1S sufficient to allow clearance for the nozzles 19 to feed theore from thehoppers 20. 21 indicates suitable uprights for supporting the superstructure 22, and 23-23 indicate suitable hand controls for regulating the flow of the ore, said controls being preferably located above and below the pivotal or ball and socket connections 24.

From the foregoing it will be seen that as the furnace heats up, the nuts 25' may be loosened to allow for the expansion of the arched roof, the abutment wall 7 serving as a brace between the roofs of adjacent furnaces, thus providing a convenient, laccessible and the strongest kind of construction for taking care of the expansion of the arched roofs without lthe necessity of using buck-stays, rods and similar appliances requiring attention at numerous places and which do not give proper support to the side walls of the furnace. Suitable inlets and outlets such as 26-27 may be provided for each of the water boxes atthe sides of the furnaces to provide for the proper circulation of water and these boxes are of course preferably connected in any suitable. manner so as to provide for a continuous circulation throughout the entire sets of boxes employed.

Referring now more particularly to Fig.

2, it will be observed that at the front of the furnace instead of employing the usual brick stack, or flue I have illustrated a suitable water jacketed iue or stack indicated by the reference character 28, the water circulating therein being in communication with the boiler 29 from which it may be used in the operation of the systems as may be desired. 100

The nozzles 19 may be water jacketed, that is to say, the tube 30 preferably ends at 31, and the nozzle 19 is preferably formed y of concentric tubes 19-19 between which water may be circulated through the inlets 105 such as 32-33.

i Of course it will be understood that furnaces, and hollow water circulating boxes Various modifications may be made in the through which said ore inlets may be shifted. 11, construction and arrangement of parts with- In testimony whereof I hereunto effin my out departingfrom the spirit of the invensignature in the presence of two witnesses. v5 tion as claimed. v l HENRY L.
