My invention relates to improvements' in eorbel blocks such as adaptecl for use" in a masonry Wall tospan a part of an opexiing in a Wall, end paicticularly o be inoluclecl in the vertical part of che Wall a1'1d exten'cl oVer ancl abutwith another member or part. Such a structure is particularly sefulin tb e constructiori of boiler settings and the corbel block in such stri1ctures is intenclecl robe" set 10 in the Wll of the boiler setting ancl eirch over aricl abut With the steam clrum of a certain typeof boiler. Theinvention is intended to lessen tbe cost of making a wall iriwhich the part of an aro'lo is used, and to Produce a better structure than th'at generally employecl. In .carrying out this idea woulcl ,make the bloek O refrac'tory material With the 'inner sicle archecl, and with the top'zrnd ba.ck generallyfiala, but With steps connectmg. 2 the flat top an'cl flat back, thesteps being of a height corresponcling to the brick courses of the acljacent Wall. The flat back is also of a height representing a multiple of brick courses ancl thus the block as a whole can 2 be conveniently set in a wall, a firm boncl made with the adj acent brick courses and the inner pari 'arching against the boiler clrum or analogous member so as to effect a closure of the Wall against said member antl proper spacing, while the top of the block forrns a support for a brick or other arch which can extencl over the drum or the like. This constructiOn and the aclvantage of its use Will be better understoocl and appreciatecl from the clesoription Wbich ollows.
Reference is to be had to the accompanying clrawings in wbich similar reference charo acters represent the corresponcling parte in all views. I
Figure 1 is a sicle elevaton of the corbel block emboclying my invention sbowing its applicati0n to a wall of a steam boiler, end
Figure 2 is an enlargecl perspective view .of the block.
The block 10 is made of refraotory material, for example fire olay, ancl it. has its inner sicle curved as sbown at 11, a flat top 12,1 flat back 14 Which is preferably perpenclieular to the top 12, and steps 13 connecting the top 60 and back, these steps forming che outer ancl upper corner p-ortion of the block. In Figure 1 I have shown how tbe block is most enerally usecl in the wall of a boiler settng and as bere illustratecl, it spans the space betvveeo theupper Parfi of the walll' andithe sieam-cl'r-um 15. It Will bebnotd thzit the bottom of he bl0el; reste on solid masonry be very expeditiously aricl therefore inexpem-- sively laicl in tbe wall ancl it Will make a beat a1id efiicient-Span' or sem arcb connect ing the wall with the1steam druno 15. 'lhe brickc0urses can be laid without cutting Or shap1ng the bricks s'o asi to make a perfect bond With the baok wall ofthe bl0ck and it 13 bounclin so tbat this bond take1i' in corii1ection ithtbe fact that the inner end of is made for the briok arh' 16 which can be laici 'over the clrum. The provision of the steps 13 serves to stagger the briok courses ancl make them offset vvith respeot to eaoh otber, so that there is no vertical straight go1nt eommon to the various courses. This 15 a cl1stinc aclvantage obtainedby the use of steps, bec'ause where a'vertical straight o1nt is usecl, che cementing material therein oracks very easily under the application o beat in service. By the elimination of a straight vertical joint, oommon to the various course's of brick, the tendency of cracking s greatly recluced.
Obviously the drum 15 can be any other member with whieh che block 10 s to connect,-and it cari be used with the advantage alrealy pointecl out. In Figure 2, blie clottecl lir1es show hoW the brick courses fit into the steps 13 of the blook so as to make a firm bonol between the block and. the said brck courses. In practice, the inner end of theblock 10 can be trinomed if desired to make it fit anol 011 the otber band, it can be steppecl out. slightly from the Wall at its underpart in a manner Well understoool by brick masons, so as to make it span slightly more than the distance between the normal wall front and the member 15.. The block can be made of any Width end in laying a W:Lll of the particular cbaraoter clesoribecl, it I back surfaces of the. block with the result that the' block is reversible and either flat end may be used as the bottom. The steps urther impart a substantially uniform thickness to che block, the thickness varying, of
7 course, t some extent, but being substantially uniform ,and within the range suchthat 'the resistance to cracking under weight and thickness of the material the greater is the tendency to crack under high temperature conditions to Which the block is subjected. Thus, the steps in addition to imparting reversibility to the bloek end eliminating the ,vertical straight joint, provide a block which is substantially unifonn in thickness end possesses substantially maximum resistance to cracking throughout.
Iclaim:
1. A corbel block of the kind decribed hav ing a flat back surface end a flat top siirface disposed substantially perpendicular to each other, a plurality of steps arranged diagonally across the cornerof the intersection of the planes of the surfaces, said steps acting to support brick courses in offset relation and eliminate straight vertical j'oints extending through saidcourses, flat ends for the block arranged substantally perpendicular t0- each other, said steps being disposed symmetrically so that either end of the block may serve as the bottom; and a slubstantially quadrantal underside connecting said ends.
2. corbel block of the kind described having a flat back surface and a flat top surfzice. dsposed sbstantially perp'endicular to each other, supinrality 0 steps symmetrically arranged acrcsS the corner of the intersection of the planes of the surfaces, flat ends for the block disposed substantially peraendiclar to each other, and a substantiaily quadrantal underside connecting said ends, the thicknes s of the block being substantially uniform throughout end Within a range such that substantially maximum resistance to cracking under beat and weight is present throughout the block. r In testimony Whereof, I have signed m nanne to this specification this 10th day of J une, 1927 v GEORGE 'ALLEN, JR.
