. BRICK FOR GAS REGBNERATING FUR S. No. 346,782. Patents 11g. 3, 1886;



$PEC'IFICATION forming part of Letters Patent No. 346,782, dated August 3, 1886. Application filed February 26, 1886. Serial No. 193,811. (N 0 model.)

To all whom, it may concern:

Be it known that 1, WILLIAM H. SMITH, a citizen of the United States, residing at Ganton, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Bricks for Regenerator Gas- Furnaces, of which the following is a specification, referencebeing had therein to the accompanying drawings.

My invention relates to improvements in the construction of bricks for regenerator gas .lowing the products of combustion to pass freely out of the regenerators, the said concave portion of the bricks, owing to their peculiar construction, formsa vortex,which gives to the waste products as they rush through the regenerators a swirling motion or action; and effectually cleans the regenerator-briok of all soot and other extraneous matter, which would otherwise adhere thereto.

Referring to the drawings, Figure 1 is an end View of abrick having a flat top.- Fig. 2 l

is an end view of a brick havinga pointed or angular top. Fig. 3is an end view of a brick having its top rounded or oval in cross-section. Fig. 4c is a view in perspective of a series of brick as arranged in the regenerativechamber of the furnace.

A indicates the main body of my improved brick, the top of which may be flat, oval, triangular, or pointed in cross-section, as may be preferred. The lower side, however, is provided with a recess, B, throughout the entire length of the brick, such recess being concave or semicircular in cross-section, as shown in the drawings.

The objects of making the checker-brick concave, or with a semicircular groove on the under side, are twofold: first, to obstruct the gas and air on the incoming side, which, in

as the waste products of combustion are pass ing out at the other side, which gives to the same a whirling action, which tends to free the bricks of soot or other extraneous matter deposited thereon, and in this way prevents the regenerators from becoming clogged up,

In the use of these bricks it will be understood by those skilled in the art of constructing regenerator-furnaces that these bricks are piled up in the air and gas regenerator-chambers at each end of the combustion or melting chamber, with one layer of brick crossing the next adjacent layer in the form of checkerwork, so as to form passages through which the gas and air find their way to the com-.

bustion-chambe r, and through which the waste products pass on the opposite end from that in which the air and gas are being admitted, as is common in regenerator-furnaces.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s

1. A fire-brick for the air and gas regenererators' of a regenerative gas-furnace, having its under side provided with a longitudinal, concave, or semicircular groove, as and for the purpose set forth.

2. A fire-brick for the air and gas-regenerators of a regenerator gas-furnace, having a concaved or semicircular groove on its under side, and plain top and sides, as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
