,To all ir/iom it muy concern.'

ylle it known. *hat I, llxnnow l). Snvxsn, a resident ot' ,i-shland, `in the county of Boyd and.. State of Kentucky, have invented a new and useful ln'iproveinent in BalileYalls for v Jiiocoinotire FireBoxes. oi which the folvided with the low'ingis a specilication.

This invention relates to battle walls .for floedinotire tire boxes. yf lThe object oi the invention is to improve the arrungenicnt of fire brick forming such baille walls, in order to reduce the weight end cost ot' the .Vire brick, and particularly to .furnish a new and improved forni of side brick ot' simple construction, which are so shaped as to be easilvY secured in the fire box, which are reversible and can be used on either side the fire box, and which also cnn be used in. lire boxes where the side walls converge toward each other. I

ln the accompanying drawing Figure l represents a longitudinal section through a .tire box provided with my improved battle wall, the section being tn k'en on the line l-l.

Fig. iig. 2 is :i transverse section on the line Qh, Fig. l Fig. 3 is a plan View of the baille wall; Figf is et perspective View ot the under side of one of the side bricks.

v.ln the drawings l represents the vfront well of the locomotiveire box. which is prousual firing opening Q 3 represents the resr wall ofseid tire box; 4: the top thereof; and 5 the grate. Extending between the front and renr side walls are the usual long ndinal tubes (3 for supporting the liiiie wall. The fire box. as shown, is provided with tour such longitudii'ial tubes il which are connected in the circulation sini-- teni of the boiler, and extend substcntiallnv parnllel to the centrnl longitudinal axis ot tbe .ire box. at least tor 'those portions o't th'b l 'ctn wlucl support the baille w all. rlhe le walls i oi' the fire box may be parallel 'to each other. but insoine ceses may con,-

'to-wit. three central rows S, and two side rows .fh-which taken together storni a sort of inverted arch extending troni side to side'o'f the tire box. The brick l0 ot' the three intermediate'rows have their lower corners cut out-, as at ll, to forni refy cessed lfaces resting upon the four cinculnl. tubes 6, and,`a'lso haveV zipartgoi thefv toward the rear wall of the tire box,r

' cent. intermediate brick per end portions of the intermediate brick`v are preferablyY sloped back or beveled slightly, ns at l2., to prevent the bricks fue ing together under 'the extreme temperatures to which they. are subjected. also, a slight' space is lett between 'the ends of adjacent brick, as et 13, for the saine reason. although this is not essential.

The brick llof the side rows are inclined between the side walls 7 vol the re boxsnd the outer circulation' tubes. .Y cisl shape. being formed substnntially'of flat plates of. the saine thicinies` throughout.' and are curved or arched atf'thei r outer edges in two directions. first in a horizontziil plane, as indicated at 15'. find second in :i vertical plane, es indicated at 16. rhis takes care o: any inequalities in the side walls ot' the lire box, and insures that the side brick will het' a firm bearing' against the side walls, even if the latter converge toward each other.. and also a lirni tion tubes. The under side of cach side brick le is provided with one or s. plurality of downwardly extending' lugs or projections 17,'two being shown. These lugs or projections are molded integral with. the brick and are shaped to forni curved bearing surfaces 1S, which abut against the outer circulation tubes 6 and prevent the brick from dropping down between said tubes and the walls of the lire box. The lower inner horizontal edges of the bricks lfl'are slightly out away. `r beveled, ns at 19. to torni longbearing surfaces extending' the full length ot' the brick, and resting directl)Y upon the circulation tubes 6. rlhe side brick consequently have in eii'ect av three-pointsuspension. that is. they bear upon the4 tubes for substantially their entire length or at both ends and Contact with the side wells ot' the re boxv at it single point. This prevents liability ot the brick tilting' in use or troni becoming vin any inanner displaced troni. the circulation tubes. The upper inner edges ot' the brick :ire also sloped back or beveled slightly. as et 20, to prevent tliein lrom fusing with the adjaunder extreme high The side brick llt are' also teni peintures.

When the side Walls of the lire box converge, different side brick longitudinally of the lire box will be of different Widths, to take care of the -varying distance between the side Walls and the -outer circulation tubes at different points longitudinally in the ire box. Preferably, the different brick Will be of such size that the inclination of all brick will be the saine. However, if desired, diffiring opening and can be placed nponthevv i set `my hand.

The inclination of the side brick is such that its Weight tends to make it'set- They are all made of such size as to be easily inserted through the tle more firmly' in lace and to Wedgein between the side Wa ls and the outer cir-cnlation tubes.
