UNITED STATES PATENT OFFICE.

EDGAR B. WILLS, OF MENDO'IA, ILLINOIS.

TANK-HEATER.

T 0 all whom it may concern:

Be it known that I, EDGAR B. WILLS, a

citizen of the United States, residing at Mendota, in the county of Lasalle and State of Illinois, have invented certain new and useful Improvements in Tank-Heaters; and I 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 andv use the same, reference being had to the aceompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification. I This invention relates to new and useful lmprovements in tank heaters, the object in view being to generally improve upon the form of construction of apparatus of this nature covered by Patent No. 908,182.

The present invention comprises essentially in a heater a return flue of any shape turning over the fire box to a point near the fuel opening and a pivotal damper within the casing covering the opening above the fire box and adapted to swing so as to admita direct draft from the fire box to the pipe or to cause the draft to pass through the return fine.

The invention consists further in a heating tank of an adjustable fire box adapted to accommodate different kinds of fuel and provided with a removable grate and also in the provision of a swinging damper mounted upon the movable grate and serving as a partition to guide the fuel in a heater.

The invention comprises various details of construction, combinations and arrangements of parts which will be hereinafter fully described and then specifically defined in the appended claims.

I illustrate my invention in the accompanying drawings, in which Figure 1 is a perspective view of a heater made in accordance with my invention. Fig. 2 is a vertical sectional view through the heater. Fig. 3 is a vertical sectional view showing the grate at its farthest limit in one direction. Fig. 4- is a sectional view on line 4-4 of Fig. 3.

Reference now being had to the details of the drawings by letter, A designates a heater which may be of any size and made up preferably of two complemental parts bolted together and adapted to be submerged underneath the surface of the water. With- Specification of Letters Patent.

Serial No. 548,918.

in said heater is a chamber B having an opening B in the top over which a sliding door C is mounted. Mounted upon the shoulders D projecting from the inner walls of the casing is a grate E having lugs E projecting therefrom which rest upon said shoulders and one end of said grate is curved vertically as at E and has a groove E in its upper edge, while its other end is provided with curved lugs H adapted to engage the recesses I formed in an imperforate alate K, affording means whereby the ashes falling upon the same may work down upon the grate E and pass through the openings therein... Said grate E, when interlocked with said plate K, may be moved back and forward and, when adjusted in the position shown in Fig. 2 of the drawings, the plate K assumes an inclined position and the fire boX is adjusted to its contracted form, whereas in Fig. 3 the grate and plate connected thereto are horizontally disposed and the apparatus adjusted for a'large fuel capacity.

The inclined portion L of the heater and upon which the plate K rests when adjusted as shown in Fig. 2 is grooved as at L and serving as means to guide the plate K as it is moved back and forth. Underneath said grates is an ash box N which, when the parts are adjusted as shown in Fig. 2, may be moved horizontally and taken out through the opening at one side of the upright portion E of the grate E. Apartition, designated by letter O, rests in the groove E and is adapted to be swung into the position shown in solid and dotted lines in Figs. 2 and 3. Vhen said partition assumes the position shown in solid lines in Fig. 2, in which position the damper rests against the wall 0' it closes the upper portion of the fire boX from communication with the opening B and affords a passageway leading to the opening B whereby air for draft purposes may pass through to the grate E and also afford means whereby the ash pan may be removed without disturbing the fire.

Pivotally mounted in a notch R formed in one end of the laterally projecting partition Q forming one wall of the return flue Q is a damper R adapted to be swung from the position shown in Fig. 2 to a position shown in Fig. 3 whereby a direct current may be derived, as shown in Fig. 2, or a return current produced by swinging the partition R to the position shown in dotted 1 lines whereby the heat may be caused to pass through the return flue and thence through the pipe S.

The operation of my invention will be readilyunderstood and is as follows :lVhen the parts are adjusted as shown in solid lines in Fig. 2, a direct draft will be established from the grate direct to and through the exit pipe S, the space intermediate the partition 0 and the opposite wall of the passageway underneath the opening B atiordii'ig means for supplying air for combustion'purposes to the grate, the air passing not only through the openings in the horizontally disposed part of the grate E but also through the openings in the upright part E lVhen the partition 0 is in the position shown in dotted lines in Fig. 2, it will serve as a means for directing the fuel as it is passed through the opening and cause said fuel to fall upon the said grate and plate and, by swinging the damper R to the position shown in Fig. 3, a circuitous current will be formed through the flue 0. By the provision of the hinged grate plate, the ashes may be drawn down through the openings in, the grate E to the box which may readily be removed without disturbing the lire. By this construction of heater as shown, the fire may be so positioned upon the adjustable grate as to come within the submerged portion of the casing. The fuel slide or damper may be removed, it not desired, and may be conveniently taken out of the casing through the opening in the top thereof.

What I claim to be new is 1. A tank heater comprising a casing having an opening therein and adapted to be submerged in water and provided with a return flue. a damper loosely hinged upon the wall of said flue and adapted to have a swinging movement within an exit opening from the casing and cooperating with the wall of the latter and said flue to form a direct and indirect draft, an adjustable grate, shoulders upon the wall of the casing upon which said grate is mounted, an ash pan underneath said grate, and a swinging partition upon an upturned portion of the grate.

2. A tank heater comprising a casing having an opening therein and adapted to be submerged in water and provided with a return flue, a damper loosely hinged upon the wall of said flue and adapted to have a swinging movement within an exit opening from the casing, an adjustable grate and plate hinged thereto, said grate being provided with integral hooked lugs, and said plate with recesses engaged by said lugs, a portion of the bottom of the heater being inclined and adapted to receive said plate.

In combination, in a heater, a casing having an opening therein and having a laterally projecting wall adapted to cooperate with the wall or the casing to form a return flue, a damper pivotally mounted in a recess at one end of said wall and .movable within a passageway leading to an exit pipe and cooperating with the wall of the casing and said flue to form a direct and indirect draft, a grate having a vertically disposed portion which is grooved at its top, its other end having curved lugs, a partition pivotally mounted in said groove, a plate having recesses in its opposite edges and engaged by said lugs, and an ash pan beneath said grates.

it. In a heater, the combination with a casing having an opening therein and having a return flue and an exit opening, a damper pivotally mounted underneath said exit opening, a portion of the bottom of the casing being inclined, a grate movable upon shoulders upon the casing and having an upturned portion grooved at its top, a partition pivotally mounted in said groove, lugs upon said grate, a plate having recesses in its opposite edges engaged by said lugs.

In testimony whereof I hereunto aflix my signature in the presence of two witnesses.

EDGAR B. IVILLS.
