SUPPORT FOR OHECKERWORK.

Application filed August 18, 1921. Serial Nb. 493,501.

To all whom itma/y concern:

Be it known that I, EARL G. Wnnprmzr, a citizen of the United States, residing at Cleveland in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Supports for Checkerwork, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

This invention relates generally to hot blast stoves and more particularly to the support for the checker work which constitutes a part of said stoves.

The object of the invention is to provide a support which will maintain the checkerwork in close proximity to the supporting arches, and also a support of such a nature that a supporting arch can be removed and replaced without disturbance or detriment to the checker-work or other part of the stove construction; and a still further object is to provide a support between the arches and checker-Work of such a nature that the entire checker load will be supported directly upon the arches through the medium of the bricks resting directly upon said arches and another object is to provide a support comprising a plurality of interlocking bricks so formed and wedged together as to prevent warping or twisting of the checker structure.

Other objects and advantages will become apparent as the detailed description of the invention proceeds.

The invention consists in the novel features of construction, and in the peculiar manner of combining or arranging the same, all of which will be fully described hereinafter and set forth in the appended claims.

In the drawings forming a part of this specification Fig. 1 is a view showing a plurality of arch walls with my improved construction of supporting bricks arranged thereon and the checker-work arranged upon said support; Fig. 2 is a similar view showing the checker-work removed and disclosing the manner of interlocking the series of supporting bricks; Fig. 3 is a plan view showing the arch walls and the supporting bricks arranged thereon; Fig. 4 is a perspective view showing the arch walls and the two series of supporting bricks arranged thereon but se arately from each other in order to more 0 early disclose the details of construction; Fig. 5 is a detail sectional view on the hne 5o of Fig. 3; and Fig. 6 is a detail perspective View of one of the supporting bricks.

As my invention relates specifically to the novel construction of support employed between the arch walls and the checker-work I have deemed it unnecessary to show any other features of the hot blast stove and in the drawings I have indicated three arch walls A as this number will be suflicient to show the assembly of a definite number of supporting bricks in order to clearly illustrate my invention.

These arch walls A are of the usual or any approved construction and upon said walls I arrange the bricks B, these bricks being preferably of a thickness slightly less than the thickness of the arch wall and in pract1ce I prefer to arrange these bricks longitudinally along the top of the wall.

The bricks B are preferably key-stone shaped as shown; that is, they are formed with downwardly tapering sides or ends as indicated at B so that the upper end of the brick is wider than the lower end and it will be noted that the brick is arranged upon its smaller or narrower end.

The bricks C are arranged at right angles to the bricks B, and straddle the arch walls as shown and rest upon said walls at their end portions only; whereas the blocks or bricks B rest entirely upon the supporting walls; and the bricks B and C are interlocked with one another as hereinafter more fully described in order to provide a series of rectangular shaped passages, and upon the bricks thus arranged I place the checker pieces D and these checker pieces are so arranged that they rest mainly upon the bricks B so that said bricks B form the main support for the checker work upon the arch walls, and so long as the bricks B are maintained in their proper relative positions the checker-work will also be held in its proper position.

In order to wedge the bricks B and C firmly together and at the same time lock them in such a manner that a supporting arch wall can be removed from beneath one series of blocks B without disturbing the relative positions of said blocks, I provide each block C with an extension E at each end, said extension E being formed with upwardly tapering sides as shown at E thereby providing an extension which is wider at the bottom than at the top and the shown in Figs. 2 and 3 and it is. obvious that the arch walls.

when the entire space within the hot blast stove directly above the arch walls. A is completely filled with bricks B and C,

wedged together in the manner shown in Figs. 2 and 3 that a rigid and fixed support will be provided for the checker pieces D.

In arranging the checker-pieces D I prefer to arrange them mainly upon the bricks B and this can be readily accomplished by placing some of the checker-pieces in longitudinal alignment with the bricks B, while those pieces which are placed transverse to the bricks B will be supported upon the ends of at least two or more of such bricks and if desired the bricks C can 'be made of slightly less height than the blocks B, a

. fractional part of an inch being ample, and

in this manner I am assured'a direct support of the checker-work through the bricks B which in turn rest entirely and directly upon As previously stated the supporting bricks B and C are tightly wedged together in the bottom of the hot blast stove and directly upon the arch supports and when so wedged in this position there is provided a rigid support for the checker-work and consequently all warping or twisting of the checker-work due to insufficient and unrigid support, is completely avoided.

By having the bricks B key-stone shaped and arranging these key-stone shaped bricks in the key-ways formed by the juncture of the bricks C having reversely tapered extensions, it will be understood that so long as the blocks C are held in place that the blocks B will be supported againstdownward movement and consequently when all of the blocks B and C are interlocked and wedged in the lower portion of the hot blast stove, it is possible to remove an arch wall I A without disturbing the blocks B and C resting thereon inasmuch as said blocks will beheld in their proper positions through their interlocking and wedging action with the other blocks resting upon the remaining arch walls. I

In this way an arch wall which has become defective can be removed and replaced and in case all of the walls become defective, they can all be removed and replaced, one at a time without disturbing the checkerwork and the support for the same which is arranged directly above and resting upon the said arch walls.

While I have shown the blocks B as tameagre Bored or key-stone Shaped and the blocks l as having reversely tapered extensions it abutment with the next adjacent extensions will provide seat ways for the wide end of the block B thereby providing a support for said block so that by holding a plurality of blocks C intheir proper relative positions the blocks B engaging the same will be held against downward movement.

Having thus described my invention, what I claim is:

1. A checker work support comprising one set of key-stone shaped bricks and a second set of bricks having reversely tapered end extensions, said last named bricks being placed end to end to provide tapering keyways to receive the first named keystone bricks.

2. A support for checker Work comprising one set of brickswider at their upper ends than at their lower ends, and a set of bricks having side extensions which are wider at their lower ends, said first named bricks being. arranged to interlock with the extensions of the second named .bricks.

3. A support for checker work comprising one set of bricks having tapering end extensions, said bricks being arranged with said extensions abutting and'providing inclined keyways, and a second set of bricks adapted to fit between said first named bricks, said second set of bricks being tapering and fitting into the inclined keyways. I 4. In a hot blast stove, the combination with the arch walls, of one series of bricks arranged upon said walls, said bricks being widest at their upper ends, a second set of bricks, straddling said arch walls and having their ends resting upon said walls, said second set of bricks having extensions which are widest at their lower ends, said first named bricks having their sides engaging said extensions.

5. A support for checker work comprising a series of downwardly tapering bricks and a series of bricks having shoulders or extensions at their ends, said shoulders or extensions tapering upwardly and adapted to engage the tapering side of Said first named bricks.

6. In a hot blast stove, a support for checker work arranged between the arch walls and said checker work and comprising one set of bricks straddling said walls and having their ends resting thereon, and a second set of bricks arranged upon said walls and between said first named bricks, said second named bricks being widest at the upper ends, and adapted to be supported by portions of the first named bricks which are widest at their lower ends.

7. In a hot blast stove, the arch Walls, a

I support upon said walls, and a checker work upon said support, said support comprising one set of bricks having end extensions widest at their lower ends and arranged end to end to provide supporting keyways, and a second set of bricks Widest I at their upper ends and adapted to fit between said first named bricks and rest upon said keyway extensions, the checker Work pieces resting upon the said second set of bricks as set forth.

In testimony whereof, I hereunto aflix my signatur' EARL G. WHELPLEY.
