PATENT FFICE.

WILLIAM DILLON, IOF WHEELING, WEST VIRGINIA.

IMPROVEMENT IN BOILER-TILE SUPPCBRTS.`

Specication forming part of Letters Patent No. 116,693, dated July 4, 1871.

To all whom it may concern:

Be it known. that I, WILLiAM DILLON, ofthe city of Wheeling, in the county of Ohio and the State of West Virginia, have invented a neuY and useful Improvement in Boiler-Tile Support, of which the following is a specification, reference being had to the accompanyin g drawing and the letters of reference thereon.

My invention relates to the supporting of the tiles or brick a-t their base, usually built in between steam-boilers, when they are horizontally set up for use on steam-boats and elsewhere.

Heretofore, in thus setting up boilers, it has been the practice to place thern from four to six inches apart, and to close the spa-ce above th e lines of their diameters between thein by building therein tiles or brick ina de to tit the annular shape of the boilers, the former iinding their support upon the contiguous sides of the boilers, the necessary result of which has been to cause an unequal expansion of the boilers, thereby perinanently depriving thein of' their cylindrical form, and producing leakage therein.

To avoid these results is the object of niy invention 5 which consists in supporting at their base the tiles or brick built in between the boilers, as before stated, by ribs or plates made fast or secured to the boilers, instead of supporting the same by the contiguous sides ofthe boilers, there being for that purpose a rib or plate at the proper pla-ce on each adjacent boiler. These ribs may be either riveted to the boilers or made fast to stirrups or saddle-plates, which extend over the top portion of the boilers, as shown in the drawing, and which latter nia-nner of attaching' thein to the boiler I think the best.

My invention prevents the unequal expansions of the boilers, because the weight of the tiles is supported by and distributed over the boilers, while the former are directly subject to the expansions and contractions of the boilers, whereas by the old way of supporting` the tiles they act as a iixed wedge between the boilers, and inilexible to their expansion, thereby causing a greater expansion or throw of lnetal on their top and bottoni portions, and which destroys their annular forni and leads to their leakage.

The drawing is a view of two boilers in position, showin g the tile-supports and a' nia-nner of their attachment to the boilers.

A, boilers; b, ribs or plates to support the tiles; c, stirrups to which the ribs are attached; D, tiles built in on supports.

IV hat I claim as my invention, and desire to secure by Letters Patent, is-

The boiler-tile supports b I), substantially as and for the purposes herein set forth.
