JOHN V. BOLAND, OF ST. LOUIS, MISSOURI.
FIRE-BRICK TILE.
Specification of Letters Patent.
Patented Nov. 13, 1906.
Application filed December 11,1905. Serial No. 291,291.
To all w/wm it may concern:
Be it known that I, JOHN V. BOLAND, a citizen of the United States, residing at St. Louis, Missouri, have invented a new and useful Fire-Brick Tile, of which the following is a specification.
This invention. relates to fire-brick tiles; and the object is to provide a hollow firebrick, or a series thereof, suitably shaped and having on their inner walls projections adapted to bear upon a supporting bar or rod, said bar or rod being essentially smaller than the opening in the bricks, so that the air may have free circulation through the bricks after they have been adjusted in final position.
In the drawings I have illustrated my invention in use in a furnace to which said invention is primarily adapted, and Figure 1 is a longitudinal sectional View of a furnace having my invention embodied therein. Fig. 2 is cross-sectional View of the furnace, a portion of the fire-bricks also being in section. Fig. 3 is a side elevation of one of the bricks before being used. Fig. 4 is an end view thereof. Fig. 5 is a side view of the central or keystone brick used in furnaces and constructed in accordance with the principles of my invention.
I will refer only generally to those parts of the furnace which do not relate specifically to my invention and have designated. the boiler by 1, the walls of the furnace by 2, the firebox by 3, the air-passages in the walls 2 by 4, and the wall transversely of the furnace by 5.
My invention consists of the series of suitably-shaped hollow bricks which form the wall or arch over the fire-box or fuel-chamber to support the wall 5. Said bricks comprise the central keystone-brick 6 and the side members or springers 7, the latter extending into the walls 2, as clearly shown in Fig. 2. Each brick has a hole 8 therethrough, so that when said bricks are finally positioned there is a continuous passage-way from one side of the furnace to the other, said passage-way opening into the air-passages 4 in the walls 2. A rib 9 is formed longitudinally in the inner upper side of each brick, said rib being of narrower width than the hole in the brick throughout its length, so that, in effect, there is a groove at each upper corner of the hole 8 in each brick. (See Fig. 4.) A bar 10 extends throughout the passage formed by the holes 8, its ends resting upon bed-plates 11, located in the bricks 7 at the sides. The bar 10 is considerably smaller than the passageway in which it is located, so that the air can pass freely through the passage-way on all sides of the said bar except the upper side, which supports the bricks by receiving the ribs 9. The plates 11 are of such size that they will not form any great obstruction at the ends of the passage-way which opens into the passages 4, into which cool air may enter freely from outside the furnace.
An arch or wall constructed in this manner will be held firmly in position and is affected to no appreciable extent by thermic variations. The bar 10 by bearing against the ribs 9 constitutes a strong reinforcement to the arch and wall, and thereby provides greater strength for the entire structure and at the same time allowing free circulation of the air throughout the width thereof.
I have shown and described my invention in its preferred construction and arrangement and am aware that there may be variations in certain details without departing from the spirit and scope of my invention.
Therefore, without restricting myself to inessential details, what I claim as new, and
desire to secure by Letters Patent of the United States, is-
1. In a furnace-wall, a series of fire-brick tiles, including a keystone and springers, having holes of substantially uniform size extending longitudinally therethrough and which, when said tiles are in use, register with each other and form a continuous passageway through all of said tiles, each of said tiles having a rib on the upper side of the hole therein and a bar extending through said passageeway against the ribs, as and for the purpose specified.
2. As a new article of manufacture, a firebrick tile shaped for use in arch construction, and having a single hole through its center, and a single rib on the upper side of the hole therein, as and for the purpose specified.
In testimony whereof I hereto affix my signature in the presence of two witnesses.
