HOT BLAST CONDUIT.

eeecrrrcarxon forming part of Letters Patent No. 340,110, dated April 20. 1886.

Application filed October '26, 1885. Serial No. 180,982. (No model.)

To aZZ whom it may concern.-

Be it known that I, FRED. \V. GORDON, of Philadelphia, Philadelphia county, Pennsylvania, have invented certain new and useful Improvements in Hot-Blast Conduits, ofwhich the following is a specification.

This invention relates to improvements in conduits for the conveyance of heated gaseous fluids.

The improvement is designed to secure a uniformity of temperature in these fluids independent of the means by which they are heated. As an example, I may cite the operation of a blast-furnace. If a hot-blast stove be highly heated and a cold-blast forced through it, the blast will be highly heated, and as the blow continues the stove will become cool, and the blast correspondingly cooled, until finally the stove becomes so cold as to no longer supply the blast with the requisite heat. It, then, the blast be switched off, so as to pass through a newly-heated and highly-heated stove, the blast will again become highly heated; but, as before, the temperature of the blast will continue to lessen throughout the blow.

My invention will be fully understood from the following description, taken in connection with the accompanying drawings, in which- Figure l is a plan of a hot-blast plant exemplifying my improvements in conduits, the furnace which utilizes the blast being shown in horizontal section; Fig. 2, a longitudinal section of the equalizer upon line b,- Fig. 3, a transverse section of the equalizer upon line a, and Fig. i an elevation illustrating a modified construction of the equalizer.

In the drawings, A indicates in plan two hot-blast stoves, which may be of any form adapted to the heating of a current of air passing through them, the means and manner of heating the stoves being as usual; B, the cold-blast inlets to the stoves, provided with valves; 0, the hot-blast outlets of the stoves and the inlets to the equalizer; D, a

furnace in which the hot blast. is to be utilizedas, for instance, a blast-furnace or a steel-furnace; E, the blow-pipes by which the hot blast is admitted to the furnace; F, the pipe by which the hot blast, after leaving the equalizer, is led to the blow-pipes; G, the equalizer, consisting of a large vessel of sufficient strength to withstand the pressure of blast, and of sufficient cross-sectional area to contain regenerative walls or filling, and, in additiomprovide passages for the air of such area as not to seriously impair the efficiency of the blast by friction; and H, the regenerative work within the equalizer, the same consisting of numerous flues constructed of re fractory material-as, for instance,fire-brickadapted to absorb the excessive heat of the blast passing through them, and to yield up theirexcessive heat to a cooler blast passing through them. There room permits of such construction the equalizer may be in horizontal cylindrical form, as indicated,the inlets and the outlets being shown as'double. The equalizer may be disposed vertically where conditions favor such disposition, the heated gaseous fluids en tering at either the upper or lower end, and discharging at the opposite end; or the equalizer may have a double vertical form,being doubled upon itself, as indicated in Fig. 4; or, if desired, the double vertical arrangement may be embodied in a single surrounding shell, with a central division-wall reaching from the base to near the top, the fluids passing both in and out at the base of the equalizer, and turning at the top over the central partition.

I claim as my invention- The combination, with an apparatus for heating gaseous fluids and an apparatus for utilizing such heated fluids, of a conduit connecting the two apparatus and provided with a mass of heat-absorbing material arranged to be traversed by said fluids.
