LUTHER L. KNOX, OF BEN AVON, PENNSYLVANIA, ASSIGNOR TO KEYSTONE FURNACE CONSTRUCTION COMPANY, OF PITTSBURG, PENNSYLVANIA, A CORPORATION OF PENNSYLVANIA.
To all whom it may concern:
Be it known that I, LUTHER L. KNOX, of Ben A von, Allegheny county, Pennsylvania, have invented a new and useful Improvement in Regenerative Reversing-I urnaces, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which-=- Figure 1 is a vertical section of oneend portion of the furnace embodying my invention; Fl 2 is an elevation looking to the left from t c line II-II of Fig. 1; Fig. 3 is a view similar in character to Fig. 1, but showing a modification; Fig. i is a crosssection of the middle portion of the arch between the gas and air ports in the constructionshown in Fig. 3'; Fig. 5 is a plan view partly broken awayof one of the sections of the arch; Fig. 6 is a cross-section on the line VI-VIof Fi 1 Fig. 7 is a crosssection on the line VIF-VII of Fig. 1; Fig. 8 is a detail view of one of the cooling members; and Fig. 9 is a cross-section (m the line IX-JX of Fig. 8.
My invention has relation to regenerative reversing furnaces, and is designed to provide means of novel and effective character for protecting certain portions of the furnace against the destructive-action of heat.
With this object in view, my invention consists in the novel construction, combination and arrangement of the parts by which certain portions of the furnace are effect ively water-cooled in a manner more fully hereinafter described.
In the construction shown in Figs. 1, 2, 6,
7, 8 and 9, I have shown my invention applied to an open-hearth furnace of the tilting hearth type. The numeral 2 designates a portion of the tilting hearth, which is in general of any well known or suitable type, and which is mounted and operated in the -Well known manner. 3 designates the stationary end or dog house of the furnace. i designates the gas lip-take, which extends upwardly within the dog house from the regenerator connection 5 and communrcatesat its upper end with the gas port 6 lead ng to the furnace. 7 indicates one of the air-uptakes leading from the regenerator connection 8 and opening at its upper end into the port 9 also leading to the furnace. The gas and air ports 6 and 9 are separated by an intervening wall or arch, consisting of an Specification of Letters Patent,
vided with a hollow cooling frame,
and the bottom member REGENERATIVE REVERSING-FURNACE.

upper covering or floor 10 of'refractory material, a lower covering 11 of refractory material, and a plurality of metal cooling boxes or sections l2 interposed between the upper and lower refractory material. These cooling boxes or sections 12 are arranged, as clearly shown in Fig. 6, to form an arch, the
which is curved in transverse section, as
shown in Fig. 7 and is provided with the skew backs 19 at its ends for the purpose ofcarrying' a refractory lining 20. The box or casting 18 -is preferably provided with. a poke hole 21, which 'is'normally filled by an extension 22 of refractory lining 20, as shown in Figs. 1 and 7. The box 18 is also provided with the water circulating connections 23. The inner end of the overhanging portion of the dog house containing the gas 9 is preferably proas shown in Figs. 1 and 2. This frame may conveniently consist of-the side members 24, the top member 25 (shown in detail in Fig. 8), 26. The top 1nember 25 is of arched form with straight end portions, which rest upon the outwardly turned end' portions 243 of the side members 2 1. These side members have similar outwardly turned lower end portions 2&9 which rest upon the end portions of .the lower member 26. The outer end of the tilting hearth 2 is also referably provided with a cooling frame 2 which'is of similar conport 6 and the air port actor for protecting those portions of the eeoling sectionsi2 g25, 26 are removably set thelfnrnacechill 25*, and their inner fac' are? directlyjexposedtothe furnace.
lh' ejcoolingfsections' 21' are, in a -similarmanner set within-the port (:hilhQjTFJ-QB wherever seen designates water circulating' connect ons for these hollow frames. These;- connections' are so arranged thatit will take the-cold water into the lowest portion of the frame members-while theheatedfwatenlis taken off at the-upper portions thereof.
In Fig. I-have shown my invention ap plied t an open hearth furnace of the-non tiltirig type. In this figure 29 designates the furnace hearth; 30-the gas up-t'a'ke; 31
one of the' air up'takes; 32 the gas port 33 the airport; and 34: the arch separating the gas and air ports. This arch is similarin construction to that shov'vn in Figs. 1 and 6,- except that instead of extending the cold water pipes downwardly within the hollowmetal sections 35, each of these sections is provided with a longitudinally extending partition or baflle wall 36, as shown in Figs. sand-5. The cold water enters each section at the lower portion thereof from a supply pipe 37, and after flowing around the end of the partition 36 and back o the end of the' wall or arch, is discharges by the pipe 38. lhe bulk head 39 is preferably of the same construction as shown in Figs. 1 and 7. 39 designates cooling boxes, which are set in the .front wall of the gas up-take 30 below the bulk head 39, and 40 indicates a series of hollow cooling boxes, which are inserted in the sidewalls of the up-take port 30, or those wallswhich separate the gas up take from the air up-take.
'lbe advantages of my invention will be readily appreciated by those skilled in the art, since it provides means of effective char-.
furnace which are subject to the most'rapid destructive action in service.
I do not limit myself to the precise forms of my invention which I have herein shown and described, since it is obvious that the imprbvementsmay be readily adapted by those skilled in the art to other constructions of furnaces; that modifications may be made in theform of the cooling boxes and in the circulating connections therefor; and that various other-changes may be made within thespirit'and scope of the appended claims.
While I have shown my invention as applied to but one end portion of the furnace, it will be understood that in practice both ends of the furnace will be of similar character. I
