Specification forming part of Letters Patent No. 173,263, dated February 8, 1876 application filed November 22, 1875.
cation The object of my invention is to prevent the too rapid decomposition or wearing away by the action of heat of the shoes or stirrers of ore roasting and desulphnrizing furnaces. This I accomplish by constructing a water tank or reservoir over the hearth, or at one side of the furnace, and from this tank I lead water-pipes down to the point'of the shoes or stirrers that are arranged to conduct and circulate water through and into the shoes through smaller pipes up and out again into the tank or reservoir, as will hereinafter more fully appear, reference being had to the accompanying drawings, and to the letters of reference marked thereon, in which- Figure l is a side elevation, partly in section; and Fig. 2 is a sectional elevation of the shoes or stirrers and pipes.
The water tank or reservoir is constructed over the hearth, or at one side if a series ot' hearths are employed, and in this instance the hearth is a rotating one, in which the driving mechanism B is shown. Large pipes G 0, two for each series of stirrers, extend from near the top of the reservoir down to near the a. hearth, to which is coupled the cross-pipes 0,
so that a circulation of water is had through the vertical pipes and the horizontal connecting-pipe constantly. To the cross-pipe O the hollow shoes D are coupled by screw-couplings a, so that they can be removed and new of lesser diameter, extend up through the bottom of the reservoir, and pass down and enter the large pipes U at right angles just below These pipes are continued down and cross through the large pipes, so that the small pipes are surrounded by the large pipes, by which means a Waterjacket is formed around the small pipes. To the horizontal portion of the inner or small pipes nipples or tubes 1) b are screwed on, which extenddown into the hollow shoes to near their points, a sufficient space in the shoe being left for the free circulation of water.
Theoperation will be as follows: The tank being filled with water, and the'hearth revolved, or the stirrers and tank being rotated, as the case may be, if the hearth be a stationary one, the water from the tank will pass down through the small pipes and nipples into the hollow shoes, and, by the action ot'the heat and gravity of the incoming water through the small bore of the tubes, pass up through the large pipes and back into the tank. Thus a constant circulation of the water will behad through the shoes and through the series of pipes, which will prevent the shoes from becoming so rapidly decomposed, worn out, or melted, which is so liable to takeplace when the ordinary shoes or stirrers are employed, by reason of the excessiveheat and the action of sulphur contained and eliminated from the ore while being reduced upon the furnacehearth.
It is not contended, however, that the action of the sulphur upon the shoes will be wholly arrested in the use of my device; but the action of the excessive heat so well known to metallurgists upon the shoes will be modified, so that the shoes can be used a much longer time.
It is evident that the temperature of the water contained in the shoes will not exceed 212 Fahrenheit.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-- In combination with a hollow shoe, stirrer, or agitator, a double pipe, or a pipe within a pipe, connected therewith or leading into said shoe, so that water may be caused to pass into and circulate in the shoe, in the manner and for the purpose set forth and specified.
In witness whereot'I have hereunto set my hand and seal.
