in adjacent to the ends thereof are bolt hoes 14 the purpose of which will also be hereinafter described. f

The parts described in the foregoingr muyY be of the usual or any suitable construct ion and the back casting 7 may have been formerly employed for supporting n fire brick bridge wall.

`My improved bridge wall comprises end or outer sections l5 :ind n series of intermediate sections 16. These

sections

15 and 16 are in the forni of substantially seginental plates and the end or head sections l5 have formed on their inner sides segmental curved flanges 17 in which :ire formed npper and lower notches 1S. On the enter side of the sections l5 are formed vertically dis- `posed laterally projecting ribs 1t) to enter the eorrngation of the boiler for an obvious purpose, as clearly shown in Fig. 2. ln

the lower edges of the sections 15 are formed y recesses 20 while the inner corners of said sect-ions are ent olf at an single :is at 21 to form spaces 22 between the same and the adjacent parts of the back casting as clearly shown in Fig. 1 of the drawings. The recesses 9.0 and vthe spaces 22 provide for n free circulation of air betwee the lower edges of the sections and the a jacent parts of the beck casting.

In the inner edges of the sections 15 are formed rectangular not-ches Q3 and the edges of the notches 23 :md the adjacentinnel and upper edgespf the sections or plates 15 nre provided with laterally7 projecting flanges 94 which extend on both sides of the plates or sections as shown. 0n the flanged npper edges of the recesses 23 adjacent to the inner edge of the upper portion of the plates or sections are formed stop lugs 25 the. pnrpose of which will be hereinafter described.

The intermediate sections or plates 'I6 have formed on cach side adjacent to the curved outer edge thereof curved spacing ribs 36 in enel] of which is formed n series of notches Il' which when the. sections or plates :1re assembled will be brought into nlinement as seen in, Fig. 3 and thus forni air passages through which air is permitted to circulate between the plates or sections and out intuitie fire box of the 'furnne-e. ln the lower edge of the sections or lates lt are lformed segmental notches 28 while. the inner corners of said plates or sections are cut ofi' as at 29 to form spaces between the inner lower portions of the sections und the adjacent portions of the bach casting. These spaces together with the spaces formed by the recesses 20 provide for wfreecircnlntion of air through the holes l in the bottom of the back casting and beneath the sections or platesof the bridge wall. By thus. permitting of the free circulation of air the plates or sections are prevented `from In order to increase the space between the plates o1' seetioilisY around the recesses or notches 28 and the cut otl portions 29 I preferably recess the opposite sides of the plates or sections :nljaeent to these parts as shown at 30 in Fig. 5 of the drawings.

In the inner edges of the sections 16 Figs. 5 and 6, are formed notches 31 whic correspond to the notches Q3 of the end plates and on the edges of said notches Ill are formed laterally extending flanges 22 whieh project on op )os-ite sides of the plntesv as shown. The flanges 32 form practically a continuation ot the upper portion of the ribs 26 on the opposite sidesof thesertions. On the upper edges of the recess 31 :ulineent to the inner edges of the plates are formed stop lugs 33 which correspond to and are for the same purpose as the lugs 2,5 hereinbefore referred t.

Arranged in the notches Q23 and 31 and adapted to he engaged with the

stop lugs

25 and 33 of the bridge wall is a section clamp'- ing bar 34 which extends the entire length of the bridge wall orthrough all of the scetions thereof shown. The bar 34 has ar ranged thereon adjacent to its ends laterally projecting clamping bolts 35 which are adapted lo be inserted through the bolt holes 14 in the vertical portion oi' the back ensting. -On the outer ends of the bolts nre arranged clamping nuts Piilbv means ot which the bnr 34 is drawn against the

stop lugs

25 and 33 of the bridge walls or sections und the latter thiis drawn beek and clamped into operative engag-ementJ with the vertnnl wall of the beck casting),r as clearly shown in Fig. 1 of the drawings. On the bolts 35 are also arranged juni nots 37 wherehy the bolts are locked after being adjusted to fasten the sections of the bridge wall in place. lly thus fastening the sections of the lfnidge wall it will be readily seen that any of seid sections may he quickly and easily removed by siniply loosening the clamping nots 3G and relensing the bar Ill whereupon the desired section may be lifted a slilieient distnnee to disengnge the stop lop; oi-.ll thereon from between the clnrnpingr bnr and adjacent. part of the boel( casting whereupon the section may be slipped out :ind n new section insorted without distnrbiiuer any of the other sections or necessitating: the removnl ot' or interfering n any manner with the snpportin plzxle 2 or the bueh casting i'.

initie sections nre arranged transversely disposed apertnrcs 3S which form air passages and which also serve as bolt holes with' which if desired may be engaged section `fastening bolts whereby one section may be fastened to the adjoining sections should the stop lugs 25 thereon fail to properly engager:

the space between the clamping bnr 34 sindt thg adjacent portion of the beck casting.
