RALEIGH J. H IMMELBIGHT, OF NEW YORK, N. Y., ASSIGNOR TO AMERICAN ARCH COMPANY, A CORPORATIOI? OF DELAWARE.
REFRACTORY ARCH CONSTRUCTION.
Application filed January 8, 1824. Serial No. 684,921.
My invention relates to refractory arch construction for furnaces and the like, and is more especially concerned with the support of the firebrick or tile composing the 5 arch. I aim to make the arch strong and secure, easy to install or take down, and easy to repair by replacement, of defective ordeteriorated brick.
, How these and other advantages can b 1 realized through my invention in a novel manner will appear from my description hereinafter of. the best construction embodying the invention that is known to me.
In the drawings, Fig. 1 shows a longitudinal vertical section through a steam boiler furnace arch conveniently embodying my invention.
Fig. 2 is a fragmentary plan view ofthe. arch at one side wall of the furnace, which is partly broken away to show the construction more clearly.
In Figs. 1 and 2, my invention is shown as applied to the main portion 4 of the arch, between the nose 5 and the ignition arch. 6,botl1 of which latter are composed of bricks 7 with undercut heads, arranged fanwise and supported'by flan ed anchor plates 8 carried by transverse (513111191 beams 9. The main portion ft of the arch is composed of transverse rows or "bungs of hung brick 10 and filler brick 11 in alternation. As shown, the-hung brick 10 are laterally rabbeted at 12, and the filler brick 11 have lateral shoulders 13 that rest on the rabbets: however, any suitable mode of interengagement may be employed. The arch 4' is sealed to the side walls by fireclay 14 or L the like, as usual. v i The hung brick 10 have undercut heads 15 that are engaged and supported by and between transverse supportin members 16.
For each bung of hung bric a pair of the supports 16, consisting of channel beams arranged face to face with the heads l5 restingon their lower flanges.-
The ends of the beams 16 extend into pockets 17 in the side walls 18 of the furnace, and
rest on metal plates 19 built in to form the bottoms of the ockets. The channel beams from separating and releasin the brick 10. As shown, they are held by lted clam 20, consisting of plates 21 with their ens:-
10, there is 16 maybe hel in the proper relative positions in any suitable manner, to keep them turned down to engage overthe backs of the channels and shorter plates 22 engaging under the upper flanges of the channels. Preferably, one beam 16 of each pair extends clear to the bottoms of the pockets 17 at both ends and is fast in the walls 18, or
may be built Its mate is preferably loose in the pockets,and so much shorter than the distance from pocket back to pocket.
back' that after the clamps 20 have been 100sened, such shorter beam 16 can be shifted endwise (and swung horizontally, if need be) suficiently to release and disengage it from the pocket 17 ,atone end. The end of the beam thus freed can be swung out across the furnace, and the other end then withdrawn." i
In installing or replacing the arch, it is ossible to insert both ends of the removable earn 16 in their pockets 17, insert all the brick heads 15 ofthe correspondin between the two beams, and then bring the bung beams together to hold the brick and tighten the clamps 20 at both ends of the pair of beams. In taking the archdown, all the,
able from the walls by longitudinal movement; refractory brick cooperatively supported by said pair of beams; and detachable beam-engaging means for normally preventing the longitudinal movement of a- I i I beam as aforesaid. 2. A- refractory ach construction compr s. i-ng side walls; a transverse beam with its ends fast in said walls; another transverse.
beam supported by said walls with clearance for e'ndwise and sidewise movement to. disengage it from them and permit its removal; refractory brick engaged and supported between said beams; and means for "normally preventing movement of the latter' beam as aforesaid.
3. A refractory arch construction compgsing cketed side walls; a transverse its ends fast in the wall pockets;
another shorter transverse beam with its ends loose in said pockets'and disengageable from them; refractory brick engaged and supported between said beams; and means for normally securing the shorter beam to the other to prevent its disengagement as aforesaid.
vWise movement toseparate them; refractory brick engaged and supported between said beams; and means for normally holding the beams together.
5. A refractory arch construction comprising side walls; a transverse beam with its ends fast in said walls; another transverse beam supported by said walls with clearance for endwise and sidewise movement to disengage it from them and permit its removal; and refractory brick engaged and supported between said beams.
In testimony whereof, I have hereunto signed in name.
