WATER HEATING FIRE GRATE.

WATER-HEATlNG FIREHGRATE.

SPECIFICATION forming part of Letters Patent No. 582,023, dated May 4, 1897. Application filed August 26, 1896. Serial No. 603,989. (No model) To all whom t may concern.-

Be it known that we, JOHN H. PHILLIPS and GEORGE H. GERBER, citizens of the United States, residing at Pottsville, in the county of Schuylkill and State of Pennsylvania, have invented certain new and useful Improve ments in VVater-Heating Fire-Grates; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to furnaces or lireboxes of heating devices, has for its object improvements on the patent to John H. Phillips, dated October 30, 1894, and numbered 528,388, and consists in certain improvements in construction, which will be fully disclosed in the vfollowing specification and claims.

In the accompanying drawings, which form part of this specification, Figure l represents a vertical section, partly in elevation, of our invention; Fig. 2, a top plan View on the line 2 2, Fig. l; and Fig. 3, a front elevation ofthe fire-pot detached. 4 p

For the purpose of illustrating we have shown our invention applied to the fire-box or fuel-chamber of a domestic stove, such as a kitchen range or cooking-stove, but it may be applied to other heating apparatus.

Reference being had to the drawings and the letters thereon, A indicates the furnace or {ire-box for containing fuel; B, the combustion-chamber, which in the illustration of its use is above and directly over the oven C of a range. or cooking-stove, and D the stack or stove-pipe.

In the fire-box or fuel-chamber A is placed the water-heating fire-pot, made in two separate sections or pockets E F, constructed of coiled pipe and made to fit the fuel-chamber, each section occupying one-half thereof and providing two adjacent ends ab, which cross the fuel-chamber transversely and are embedded in the fuel, while the spaces between said ends and between the coils afford ingress for air to supply oxygen to the fuel in the center and throughout the depth of the fuel in the fuel-chamber.

On the front, back, and outer ends of the section is supported above the bottom f of the combustion-chamber by any suitable means to allow the products of combustion to envelop the pipe of the section which traverses the combustion-chamber from end to end, as shown, or from side to side, if desired, but the former construction is preferred, as it en* ables the combustion-chamber to be cleaned readily by moving the ashes from between and under thecoils of pipe toward the fuelchamber.

The section G extends throughout the combustion-cllamber and greatly augments the heating capacity of the fire-pot. From the section G a section H may be extended into the stack or pipe D to still further increase the heating capacity, and to the upper end of the section Da pipe g may be connected to conduct the hot water or steam to any desired place for use.

I indicates a tank designed to be placed outside the building, or in any preferred place,

and is connected with the fire-pot by pipes h,

communicating with the section H, and 7c, communicating with the lower ends of the sections E F, respectively, and water is supplied to the iire-pot through pipes t' 7s, with which the pipes t' 71: also communicate to maintain circulation.

As constructed, either of the sections E F may be used separately or either may be removed for repairs or renewal without disturbing the other, or they may be used together.

The water-tank I may be provided with suitable pipesfor conducting water to any desired place for use and with suitable pipes for drawing off the water and accumulated sediment,

all of which is within the skill of the artisan and requires no illustration or further elucidation.

Having thus fully described our invention, what we claim is- 1. A water-heating fire-pot having two independent and adjacent pockets, the said pockets being formed of coiled and continuous piping.

2. A water-heating re-pot having two independent and adjacent pockets, the said pockets being formed of coiled and continuous pipingand the pockets and the convolutions of the coils being spaced so as to permit the iow of air between them.

A wate1-heating fire-pot having two independent and adjacent pockets, the said pockets being' formed of coiled and continuous piping and the pockets and the convolutions of the coils being spaced so as to permit the flow of air between them, in combination with a section of pipe traversing the combustionchamber and connected with the pipes of both pockets of the fire-pot.

In testimony whereof we affix our signatures in presence of two witnesses.

JOI-IN H. PHILLIPS. GEORGE I-I. GERBER.
