FIRE-KINDLER.

SPECIFICATION forming part of Letters Patent No. 415,734, dated November 26, 1889.

Application filed liay 17, 1889. serial No. 311,115. (No spechnens.)

To @KZ whom may concern.-

Be it known that I, PARRY L. RANDALL, a citizen of the United States, residing at Portsmouth, in the county of Rockingham and State of New Hampshire, have invented a new and useful Fire-Kindler, of which the following is a specifcation.

This invention has relation to fire-kindlers, and is intended forV kindling the coal direct and without the aid of fire orkindling wood.

Among the objects in view are to provide an inexpensive and safe kinclling material formed in convenient blocks adapted to be broken, the nature of the kindler being s-uch as to create when ignited an intense and lasting heat, which, without the aid of kindlingwood, will in a vervfew moments thoroughly ignite the coal, and this so thoroughly as to render the same capable of creating steam, by which the invention is especially adapted for use in steam-engine boilers, locomotiveboilers, stoves, and, in fact, anywhere wherein it is essential or desirable to provide a quick and intense heat.

\Vitl1 these general objects in view the invcntion consists in the mixing and molding of certain ingredients, and, further, in chemically and otherwise treating the same, all as will hereinaftor appear, and be particularly pointed outin the claims.

Referring' to the drawings, Figure l represents a perspective of a fire-kindler block consiructed in accordance with myinvention, and Fig. 2 is a transverse section of the same.

Like numerals of reference indicate like parts in all the figures of the drawings.

In practicing my invention I first mix thoroughly six parts of finely-sifted wood or coalashes with on'e part of calcined plaster and sufficient water to make pliable for molding. By suitable molds, preferably of substantially brick form and having transverse and longitndinal beads or ridges, I form brickshaped blocks 1, having intersecting channels 2, dividin g the block or brick into smaller sections 3. About ten minutes is sufficient to give the block the required form, after which the same is placed in a kiln or oven,

gills of oil.

where the water is evaporated and where it is allowed to remain from five to six hours. The block is then removed and permitted to cool, when it will be seen the same is of a very porous nature. I then place this porous block in a tank of unexplosive high-test gasoil, in which it is allowed to remain some three or four hours, or until thoroughly saturated with the oil. 'llheblock is then placed upon suitable brackets or shelves and pernitted to drip and partially dry on the outside, after which it is given an outside coat-- ing of coal-tar, said tar having been boiled to such a consistence as to harden in a few moments after the coating. The coating of tar seals all the pores of the block and prevents the evaporation of the same and permits the block to be preserved for a great length of time and to retain all its combustible qualities. i

By practice I have ascertained that an ordinary hard-coal fire will contain about three After the brick or block has burned out the same will by a slight raking erunble to powder and pass between the gratc-bars.

I do not limit .my invention to coating the block. with coal-tar, as when the block is to be used within a short period of time such preservative is unnecessary. By practical test I have been able by the employment of this kindler to create thirty pounds of steam in a steam fire-engine in seven minutes and a half.

Having described my invention, what I claim isl. A fire-kindler prepared by mixing wood or coal ashes and plaster, molded in any suitable shape, burned or dried, and bathed in oil, as an article of manufacture.

2. A fire-kindler prepared by mixing wood or coal ashes and plaster, molded in any suitable shape, burned or dried, and bathed in oil, and provided with a coating of tar.

As a new article of manufacture, a firekindler composed of six parts of wood or coal ashes to one part of calcined plaster, mixed together with water, and subsequently molded and burned to form a porous brick, In testimony that I claim the foreg'oing as Which is batled in oil and finally ooated with my own I have hereto affixed my signature in o tar, as set forth. presence of two Witnesses.
