' BArrLn-sLo'r BLOCK.

Application filed June 16, 1927. Serial Nos-199,160..

.My invention relates to improvements in battle slot blocks such as are used in a masonry wall to provide a slot for an inclined baffle. Such a structure is'often seen in boiler settings. The objectof my invention is to produce a simple block which can be used to advantage in the customary brick with a battle slot therein andfwith the baifle wall and can'be disposed in series upon=both sides of the baflie so as-to form an inclined slot for the baflie and abutting wall and both sides of it. y I 1 1 Y My improved block is adapted for use: as stated with abrick wall and to this end it is made of a height representing amultiple of the thickness of 'an ordinary commercial brick, that is to say,-it will be the heightof one brick, ,two bricks, or more as desired, 7 and thus it is very easilybuilt in with the brick wall and forms an easy and perfect bond. In building the wall to abut with an inclined battle or similarly inclined member, it is difficult to break and shape the brick to abut properly with the bafiie and provide a e .tongue is. preferably of the same height as slot therefor, and it is alsodifiicult to make a neat-"and suitable job of' the work. My invention comprises a block generally; rectangular but having on one side an inclinedface from which rises an outwardly projecting tongue, thus dividing the face into two parts, or in other words forming inclined recesses at the two inner corners of the block.

By shaping the block in this manner, it is very easy to apply it to a bafiie and to a wall, and it can be applied on either side of a battle or the like, or it "can be applied on either the right or left wall of a baflie with the greatest facility.

It is also easy to produce an inclined vbailie slot in which the battles may be on both sides of the block when desired. By the construction shown, the block when used one side up fits against the one side of the inclined baflie, and'when used the other side up fits against the opposite side of the bafiie, and when applied to the left wall of a baflie, the slot will be on one side of the block, and when the block is applied to the right side of the baffle,

, the baflie slot will be on the left side of the block, all of which will be better understood from the description which follows. It will also be understood that while I refer to a block useful in forming an inclined bafiie slot, it can be used to advantage in come plating a wait against any inclined member itself, and V and to form a slot which the member can expand.

The block 10 is of any suitable refractory material and one end portion isofrectangular shape, but the opposite end orside has an inclined face 11 from the-middle portion of which rises a protruding tongue 12. .The

The object of this is to enable it to be laid in a masonry wall and for the brick courses to come into the right height against the block, thus making it easy to lay them and also causing a better bond.

It will be seen that when the two blocks are laid in opposition, for example as in Figure 4, with one block having the long part of the tongue upward,and the opposite block having the long part of the tongue downward, or in otherywords when the blocks are not the same side up, the opposed tongues will meet and an inclined slot will be formed between the blocks, and on each side of the tongues 12, so'that an inclined baffle 13- can be placed in one of the slots, andthe other slot closed asv by a wall 14, or the blocks may be laid in thecenterwall with bafies 13 or similar parts in both'slotsJ-hat is an bath. sides of the bleak Therefore, it will be understood that in la ing a I Wall't'o provide for a baffle as 13, the locks on one side of the baffle are the other side up from those on the opposite side of the baffle. Thus it will be seen that the Wall can be laid 'u 'shugly against the bafile on both sides,

making a perfect joint andalso a perfect, slot and effecting a tight closure Which will a in no Wise interfere With the free expansion of the battle It Will likewise be evident that theblccks can be readily laid in the masonry Wall, bonded like the bricks of the Wall and applied to either-side of a wall, so that bafiles' 13 or other inclined members can enterthe islets formed as stated.

Thus it Will be seen that byn'iy sithple ffo'rm of block, I am enabled tolay a Wall more neatly and better than by the usual practice, and at far less cost. Attention is further called to the fact that the tongue 12 is preferably of the same height as the body of the block, and that its outer. face 12" is preferably parallel with the opposite face of end face beingihclined, and a tongue projecting rom said inclined fac'e.
