FURNACE-ARCH CONSTRUCTION.
Application filed July 25, 1925. Serial No. 46,017.
My invention relates to improvements in the means for supporting refractory bricks in furnace roofs or arches, relations, and pertalns more and in similar particularly to a construction of this character for sustaining or supporting the bricks at the nose or end of the roof or arclrin such manner that they will'not be subjected to stralns due to the weight of the parts', and those due to the varying temperatures,
but will be independently supported and will not impose the1r weights upon one another.
, Stated somewhat differently, in \the new construction incorporating embodiment of the invention,
the preferred the sectorshaped holders or supporting members for the bricks or refractories are so designed and arranged, and the refractory shapes are so proportioned, that when the several parts are assembled the weight will be carried en'- tirely by the metal construction, and spaces allowed between the bricks or refractories to avoid their carryinganything but their own weight, and as the construction is heated and expansion takes place,
by the iron-work,
pressure will be cared for the expansion the bricks being entirely relieved in this regard. I
More specifically,
ment of the invention as exemplified in the preferred embodiina fan-shaped construction, I employ amain support and detachably position thereon a plurality signed to carry with one another, the
the bricks strai of pocket or socket members deout of contact ns due to the weight of the parts and'those caused by the varying degrees of heat bein ly on the supporting elements,
the refractories themselves.
To enable those 0 imposed soleand not on acquainted with this art to understand the new construction and its various structural and fun tages,
ing a part of this specification,
ctional advanin the accompanying drawing, form- I have illus-' trated a desirable and preferred embodiment .of the invention, and for simplicity I have employed like reference cha racters for the same parts throughout the several views.
In this drawing,-- Fig. 1 is a fragmentary, through the end portion of vertical section a furnace-roof drawing, it Wlll be seen that a portion only of the main brick arch 11 of the flat type is illustrated, the bricks thereof being supported or suspended from above by pipes 12, 12, carried on suitable beams 13, hangers 14 depending from such pipes, and Shoes 15 fitted in slots or grooves of the bricks which unitedly form the arch or roof for the furnace.
Above the rear or inner end of this arch, there is a pair of spaced, cross I- beams 16 and 17, and mounted on these I provide a series or row of spaced-,quadrant members elevation of the 18, 18, bolted at 13 to the web of'the supporting beam 16, and each having a hookshaped part 21 engaging the lower flange of the companion beam 17, and another section 22 bearing on the bottom flange of the beam 16. r
The exact and precise manner of mounting such supporting members 18 is of minor importance, and any approved or approriate method, such as will readily occur to those skilled in this art, may be employed.
The quadrant sector 23 of each such element 18 comprises a web' having a curved edge, a main aperture 24 through such web, and small holes therethrough, referred to hereinafter. Each such web or quadrant portion has four'pairs of horizontal lugs or ears 25, 25, outstanding in register from its opposite sides.
For holding the several bricksin fan-or arcshaped formation or relation on such common support 18, I use a plurality of metal, sector, pocket or socket members 26 and 27, of two slightly different types, although in their general characteristics they are much alike.
Each of the socket members 26, 27, of each vertically-disposed set or group has a flaring recess 28 with opposite walls29 and 31, each supplied with a longitudinal rib 32 on its inner surface designed and intended to fit in oppositely-disposed grooves 33, 33 in opposite, diverging faces of two tapered bricks 34 intended to be received in the socket or pocket, the ribs supporting the bricks and preventing them from falling out, as will be readily understood.
As is indicated in Figs. 4 and 5, the ends of such pockets or recesses are open, where by the bricks or refractories may be easily slid into place before the member 26 or 27 Thus the three lower rows of such brickcarrying members, which bear against one another, as shown, are supported by such bolts, and their turning on these sustaining elements is restricted or limited by the engagement of the edges of their arms 35 with the corresponding, outwardlyprojecting lugs or abutments 25 referred to above.
By removing the proper bolt, any one of such brick-sustaining members 26 may be easily and readil taken out to replace.a burned or injured brick by a new one, and replaced with equal facility, it being assumed, of course, that the bolts are accessible for such removal. I
The brick-carriers of the top or upper row are like those of the lower rows except that the straddling ears or arms are somewhat longer and of slight hook-shape, whereby they may not only bear against, but also hook around, the corresponding lugs 25, as is clearly depicted in Fig. 1.
'As in the previous instance, these refractory-supporting socket-members rest on or contact with the lower ones, so that all of them may be considered as bearing on one another in series, each resting on the one below, at least in part, and sustaining those above, at least partially, the group forming a fan-shaped or arcuate ensemble.
To remove an upper pocket-member and its brick or bricks, they are rocked upwardly somewhat until the ears or arms 35ers If preferred, the second row of bricks from the top may be mounted as are those of the upper row, or if desired, all of the rows of bricks may be mounted in either manner,
but the present preferred method is that depicted in the drawing and described above.
Substantial modifications and changes may be made in this embodiment of the invention and still" incorporate the essential. features of the invention as defined by the following claims and without sacrificing any of the material benefits arising from employing the invention.
I claim:
1. In a furnace-roof construction, the combination of a support having an outstanding lug, a first pocket-member adapted to accommodate a brick in it and constructed to hook around said lug, and a second underlying pocket-member adapted to accommodate a brick,-said first ocket-member maintaining such interlocking engagement with said lug by hearing by gravity on such underlying pocket-member.
2. In a furnace-roof construction, the combination of a support having an outstanding lug, a pocket member mounted on said support and adapted to hold a brick, a second pocket member designed to hold a brick bearing on said first pocket member and against said lug.
3. In a furnace-roof construction, the combination of a support, and a plurality of pocket members mounted on said support and resting on one another in series, each of said pocketl members being constructed to accommodate one or more bricks, the latter thus supported being out of bearing contact with one another.
4. In a furnace-roof construction, the combination of a support, and a plurality of converging pocket members mounted on said support and resting on one another in series, each of said pocket members constructed to accommodate one or more bricks, the latter thus supported being out of bearing contact with one another.
5. In a furnace-roof construction, "the combination of a support having oppositelyextending outstanding lugs, and a pocket member adapted to accommodate a brick having spaced arms to straddle said support and engage the corresponding lugs.
6. In a furnace-roof construction, the combination of a support having a series of oppositely-extended outstanding lugs, and a series of pocket members ada ted to accommodate bricks, said members caring on one another and each having spaced arms straddling said support and engaging its oorwhich said arm is designed to bear, and'a responding pair of lugs. bolt extended through the apertures of said 7. In a furnace-roof construction, the arm and support. 10 combination of an apertured support, a In Witness whereof 1 have hereunto set 5 pocket member having an apertured arm my hand and seal.
and. adapted to internally accommodate a C brick, said support having :1 lug against FRANK B. BIGELOW. [1 s.]
