STOVE.

SPECIFICATION forming part of Letters Patent No. 515,147, dated February 20, 189%. Application filed August 4, 1893. Serial No. 4:82.364:- (No model.)

To 00% whom, it may concern:

Be it known that we, JAMES A. HORTON and SAMUEL M. QUEST, citizens of the United States, residing at New Castle, in the county of Lawrence and State of Pennsylvania, have invented a new and useful Stove, of which the following is a specification.

Our invention relates to improvements in heating stoves, the objects in view being to construct a stove wherein a draft of warmair shall be fed to the fuel at a proper point, the combustion increased, and the fuel saved; and which is adapted to efficiently and constantlyfeed to the fire-pot the said fuel, the whole combined to produce a stove capable of efficiently consuming in an economic manner the slack grades of coal.

With these and other objects in view the invention consists in certainfeatures of construction hereinafter specified and particularly pointed out in the claims. 7

Referring to the drawings:Figure l is a perspective view of a stove embodying our lnvention. Fig. 2 is a vertical transverse sectional view of the same. Fig. 3 is a similar view at a right angle thereto. Fig. 4 is a detail in perspective of the magazine.

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

The stove consists, in the present instance, of the usual base 1, the firepot 2, the cylinder or body portion 3, and the cap or crown 1, and these parts may be of any desired design and have any configuration or ornamentation preferred, the same forming no part of our invention. At diametrically opposite sides of the-cylinder 3 the same has bolted thereto or cast thereon upon the outside, though it may be upon the inside if so desired, a pair of vertical draft-pipes 7, Whose upper ends are outwardly bent at 6 to form air-receivers and whose lower ends are inwardly disposed and terminate in discharge ends 8 directly above the firepot 2. These pipes may be securedin position in any suitable manner, for instance, as shown in the drawings, they may be secured to the cylinder of the stove through the medium of clips 9. Theback of the cylinder at its upper end is provided with the usual ofiset 10,in the upper side of which the flanged pipe-opening 11 is formed.

Located in the cylinder of the stove, and in the present instance supported by the crown 4, is the truncated cone-shaped magazine. 12. This magazine consists of upper and lower bands or rings 13 and 14, respectively, the two being connected by means of curved sections 15 bolt-ed at their opposite ends to the rings and provided with a series of openings or inwardly beveled slots 16. The lower end of the magazine is flared, and the upper end is provided with a surrounding flange 17 which is seated in the upper end of the crown of the stove and is thus supported in position.

A vertical draft pipe 18 is located concentrically within and with relation to the magazine, and extends from a pointslightly below the same to a point near the upper end thereof, where it is provided with a transverse branch 19 that passes through an opening 20 in the magazine and terminates opposite the offset 10 in which is formed the flanged pipeopening. The lower end of the central draftpipe 18 is flared and as before stated terminates slightly below the magazine directly over the firepot.

This completes the construction of the stove and the operation thereof is as follows:(lold air is fed into the air-receiving openings 6 at the upper ends of the pipes 7, and in passing down the pipes is, by contact with the surface of the cylinder, warmed more or less, and finally is discharged in a comparatively heated condition through the discharge ends 8 of the pipes 7 into the body of coal within the firepot and lower end of the magazine. This warm air of course facilitates combustion and the flame from the coal gains access to the body of coal within the magazine through the pipe 18 therein. The hot air and flame from the coal also pass up through the pipe 18, as do the gases, and said pipe being perforated at intervals as indicated at 21 from its lower end to a point opposite the upper laterally disposed portion 19, said warmed air is to a great extent fed from the pipe to the coal. The smoke, gases, and heated air finally pass through the offset 10 and to the chimney.

By our invention it will be seen that no choking of the coal within the magazine is possible, in that the same is flared gradually toward its lower end so that a constant and efficient feed at all times takes place. The air previous to its introduction into the firepot is heated by contacting with the hot surface of the cylinder and is discharged into the firepot in this condition. This draft of course accelerates combustion and yet does not waste coa],in that it is already primarily heated.

We do not limit our invention to the exact details of construction herein shown and described, but hold that We may make such variations therein as are Within the knowledge Of the skilled mechanic.

The flame and heated air reach the center of the body of coal in the magazine through the pipe 18, thus igniting the same and greatly facilitating its combustion and aiding in its feed.

Having described our invention, what we claim is- 1. In a stove, the combination with the body portion provided at one side with an offset having a pipe-opening, of an internal magazine,-and a central pipe located in the magazine and having its upper end transversely disposed and terminating opposite said offset, substantially as specified.

2. In astove, the combination with a stovebody, of an internal magazine supported therein, a central pipe located in the magazine and provided with perforations, and having its upper end laterally disposed and terminating opposite the pipe-opening of the stove, substantially as specified.

3. In a stove, the combination with a central magazine, of an internal up-draft pipe located therein and terminating at its lower end adjacent to that of the magazine and above the fire-pot, and at its upper end adjacent to the upper end of the magazine and opposite the chimney-opening, substantially as specified.

4. In a stove, the combination with a cylinder or body-portion, of opposite external draft pipes arranged at the sides of the cylinder, said pipes having their upper ends outwardlydisposed to form air-receivers and their lower ends inwardly disposed to form air-discharges and extending into the cylinder above the fire-pot, substantially as specitied.

In testimony that we claim the foregoing as our own We have hereto affixed our signatures in the presence of two witnesses.
