This invention relates to structures suchasraters for furnacesand the like, and

recu particularly to an improved tile therefor.

The invention has for its Ob ect to provide a recuperator wherein horizontally extending flues or passages are provided between rows of vertical flues or passages. A

further obj ect'of the invention is to provide a tile adapted to be used in a structure of this kind, adapted to form the vertical and horizontal flues when associated with similar blocks and which are adapted to hold each other in proper spaced relation. A further .5

object is to provide a tile which may be easily 7 built into a recuperator structure ofthis kind, and wherein the vertical joints between blocks" 29 The invention may be readilyundersmodj by reference to the accompanying drawings, wherein, Figure 1 is a perspective view of two of the tiles disposed side by side in the manner in which such tile would ordinarily be set in a recuperator construction.

Figure 2 is a vertical section through a portion of a structure formed by said tiles.

Figure Sis a plan view of a base or sealing tile to be used in combination with the tiles of Figs. 1. and 2. i

Figure 4-. is a transverse section through ne of said base tiles on the line TVIV of ig. 3.

Figure 5 is a vertical 'section through a recuperator built from tiles of the type embo dying the present invention.

Figure 6 is a plan view of one of the special tiles providing for the vertical passage of the gases from one horizontal flue to another.

- Figure 7 is a longitudinal section'through one of the tiles, thissection being at right angles to the plane of the section of the blocks in Fig. 2'.

Referring to the drawings, 5 designates generally the rectangularbody of a tile having a vertical opening therein which is preferably divided by partition walls into a plu- I rality of small vertical passages 6. 1 7 5o Projectinglaterally from the top of the block are side flanges 7 and 8, flange 7 being widerthan flange 8. At the bottom of the block are similar flanges 7' and 8. .Flange 8' is .on theopposite side of the block from Wide flange 7 at the top, and is wider than joints in an flange On that body at the u per end of the block 18 a lateral flange 9 an at the opposite end is a flange 10. Flange 9 is pref-' erably of greater. wldth than flange 10. At the bottom of the block are similar end flanges 0 9' and 10, and the latter, diagonally opposite flange 9, is wider than flange 9'. As thus constructed the tiles when fitted tother form the vertical flues 6, and also form orizontal passages 11, which latter are connected b transverse passages 12.

Theb ocks will break all vertical joints by reason of the diagonally opposite flanges being respectlvely wider or narrower.

' The lower ends of the block are prefcrabl recessed, as indicated at 13 to receive a ii 14 atthe top of the block beneath it, as shown. The blocks or tiles may be'used in conjunction with blocks 15 having central openings t6 adapted to line up with fines 6, and having ribs 17 on their upperfaces and recesses'18 on their lower faces. These blocks are for 'use at the top orv bottom of a column of the tiles .5.

InFig. 5 T have shown a recu orator 20 so constructed with tile as describe In this construction 21 is the cold-air inlet and 22 the hot air outlet to burner 23. At 24 is the waste gas'supply passage and at 25 is the outlet or flue connection. The tiles 5 are arranged as shown so that air from passage 21 to passage 22 must rise through the several vertical passages 6 in the tiles, 22 isa gas inlet passage.

' The waste gases travel in a sinuous path from chamber 24 to passa e 25 through" the horizontal flues 11. The flan es of some of the blocks are cut away, as'in icated at 26 in Fig. 5, and as shown by the dotted lines of Fig. 6 to connect the ends of the horizontal tion, and that they may be easily and cheaply assembled into an eificient recuperator structure. a 'While I have illustrated a preferred embodiment of the invention, It will beunder 11c having a body portion with; a passageway stood that various changes and modifications may be made within the scope and spirit oi the appended claims; v

I claim as my invention: Y 1. A recuperator made up of tiles each at each end-of the body being wider than the the air inlet and outlet chambers,

corresponding flanges at the other end of the body, said tiles being built into columns and fitted together to form vertically extending passages therethrough and horizontally extending passages therebetween.

3. A recuperator comprising a suitable housing, having air inlet and outlet'chambers and having waste gas inlet and outlet chambers, and a plurality of vertical flues between a plurality of horizontal flues between the waste gas inlet and outlet chambers, some of the horizontal flues bein above others of the horizontal flues and being connected at o posite ends so as to provide for the back and forth travel through the horizontal flues, and transverse passages between some of the vertical flues connecting some of the horizontal .flues with other horizontal flues in the'same plane. 4. A recuperator including a housing, an

' air inlet passage at the bottom of the housing, 7

and an air outlet passage at the top of the housing, a plurality oftiles interposed between the air inlet and outlet passa e, said tiles having alined vertical flues theret rough and having lateral flanges thereon to maintain the tiles in s aced relation and rovide horizontal flues etween adjacent'ti es, the

lateral flanges of some of the tiles being partially cut away to provide a'connection between horizontal flues at different levels, and means for introducing waste gases into some of the horizontal flues and withdrawing waste gases from other of-the horizontal flues.

5. A recuperator including a housing, an air inlet passage at the bottom of the housing, and an air outlet passage at the. top of the housing, a plurality of tiles interposed between the air inlet andoutlet passage, said tiles having alined vertical flues therethrough and having lateral flanges thereon to maintain the tiles in spaced relation and provide horizontal flues between adjacenttiles, the lateral flanges of some of the tiles being partially cut away to provide a connection between horizontal flues at difierent levels, and

' body portion,

means for introducing: waste gases into some I I of the horizontal flues and withdrawing waste gases fromrother of the horizontal flues, the

- ateral flanges of said tiles being provided on four sides thereof, whereby thehorizontal -flues extend in two directions into the structure, whereby gases ma circulate around all sides of substantially a l of the tiles. V 6. A recuperator made up of tiles each havzontally extending passages continuous in two I directions at right angles to one another.
