COAL-OIL STOV E.

SPECIFICATION forming part of Letters Patent No. 271,215, dated January 80, 1883.

Application filed July 15, 1882. (No model.)

To all whom it may concern: Be it known that I, JosEPH W.BROWER, of Indianapolis, Indiana, have invented a new and useful Improvement in G0al-Oil Stoves, a description of which is as follows, reference being had to the accompanying drawings, in the several figures of which like'letters indicate like parts. 7

My invention belongs to that class of stoves which are heated by coal-oil lamps; andit relates, first, to a safety-valve and condenser; second, to the top having inclined sides; third. to the flange or deflector around the base of the shell, and also to the various combinations of these as hereinafter set forth and claimed. My object is to produce a stove which shall be simple in construction, safe in use, and yet produce perfect combustion without heating the oil-reservoir, and to furnish an escape for any heated gas from the reservoir through a safety-valve.

In the drawings, Figure 1 represents a vertical section of my device; Fig. 2, a side view with a portion. of the casing cut away, showing a longitudinal section of the burner; Fig. 3, a top view; Fig.4, a top view ofthe burner and wick-tube; Fig. 5, a longitudinal section on the line y y, Fig. 4. Fig. 6 is a crosssection of wick-tube and inclosing-chamber.

My reservoir for oil is indicated by the letter D, andFistheopeningfor filling,which isclosed by an ordinary screw-cap. Upon this is fixed a gas-chamber, O. The wick-tubes f are connected with this air-chamber, and the wicks w to pass down through the gas-chamber into the reservoir. The sides of the wick-tubes are pierced with holes cc 0, and alarger opening, e is made in the wick-tube whereit meets the top of the gas chamber. These openings allow the oil to escape which is drawn up after the lamp is blown out, and prevent its running over the top of the wick-tube. This oil settles and passes through these openings and other openings, h h, and again meets the wick, and when the lamp is lighted will be the first oil drawn up and consumed. About the lower portion of the wick-tubes are fixed pyramidal chambers I), which have openings in the ends These chambers allow air to pass through them, and serve to keep the wick-tubes cool,and to house the oil that drips from the top ofthe wick-tubes or passes through theopeningsin the sides. 7 The wicks are moved up and down by the ordinary toothed wheel, as shown. The wick-tubes and inclosing-chambers are surrounded by a screen orair-chamber, 13.

a a are the cones surrounding the flame when lighted, and are of the ordinary kind.

A is the shell or casing of the device, having deflectors g, which throw all the heat to the central opening in the top. The sides of the top are inclined, as shown, 8 s, Fig. 1, and are jointed water-tight to the shell, so that the water and steam will be carried away to the sides through suitable perforations located at the joint, and not be allowed to fall into the lamp. Shell A is hinged at K and latched at K for convenience in use.

E is a safety-valve and condenser connected by the pipe 0 with the gas-chamber 0, and

having a return-pipe, 0 connected with the oil-reservoir, for carrying thither the condensed vapors and oil that may be collected in the condenser. Any heated vapors or gases which collect in the gas-chamber C will pass up the pipe G, and will either force up the cap E and escape into the air or will be collected and returned to the oil-reservoir by the pipe 0 My oil-reservoir is protected from heat by the superimposed gas-chamber O and by the chambers about the wick-tubes,and. the perf0-.

rated wick-tubes allow the lamp to be blown out without driving the gases or heated vapors into the oil-reservoir or gas-chamber.

There is no puffing noise, no explosive return of gases forcing the wick up in the tube, no charring of the wick below the flame, and the lamp will stand and steadily burn where it is set by the wick-raising wheel. The perforated screen B furnishes plenty of air and aids in keeping the lower parts cool. B is a flange or deflector aroundthe outside of the shell or case, to preventsmoke or vaporfrom rising, and also for drawing cold air in underneath. The arrangement of my oil-reservoir and gas-chamber has another advantage. The oil can never rise higher than the level of the opening F, and by placing this on the lower section, D, the oil can never enter the chamber 0. The deflectors g g thtfbw the heat to the central opening, as I hanh said, and thus concentrate its power, and a small or large vessel can be iug to the sides, which are perforated at suitmore easily heated than in stoves where de flectors are not used.

What I claim, and desire to secure by Letters Patent, is

1. In a coal-oil stove, an oil-reservoir having a closed gas-chamber superimposed thereon, to the upper surface of which gas-chamber the wick-tubes are rigidly attached, in combination with a safety-valve attachment, substantially as described.

2. In a coal-oil stove, a safety-valve and condenser connected by a pipe with the gas-chamher and by a return-pipe with the oil-reservoir, substantially as described.

3. In a coal-oil stove, a closed gas-chamber superimposed upon an oil-reservoir and rigidly connected therea ilh, in combination with an air-screen which surrounds the wick-tubes,

and means for conveying heated gases from the gas-chamber to the open air by means of a safety-valve, substantially as described.

4.. In a coal-oil stove, a chimney or body having the top inclined from the central openable intervals along the line ofjun'ction of the top and sides, which joint is made water-tight to carry away water and condensed steam, substantially as described.

5. In a coal-oil stove, an oilreservoir, 1), having an opening, F, a gas-chamber, 0, snperimposed thereon, in combination with the air screen or chamber 13, the lamp-burner, and the shell A, having deflectors g g, and the top with inclined sides 8 s, substantially as described.

6. The combination of the oil-reservoir D, gas-chamber O, safety-valve E, with pipes O and burner having perforated wick-tubef, and cooling-chamber b, with shell A, screen B, and flange B substantially as described.

In Witness whereof I have hereunto set my hand this 12th day of June, 1882.
