SPECIFICATION forming part of Letters Patent No. 496,401, dated May 2, 1893.

Application filed April 8, 1892. Serial No. 428,278. No model.)

employed to heat a body of water which will radiate the heat imparted to it, and thus serve as a substitute for stove, iire place and furnace heat.

The object of my invention is to provide anefficient heater of this class which is portable,

having few parts, not likely to get out of or der, and which shall be cheap to construct, and can be run at small cost.

In the preferred form, my invention comprises a radiator formed by two concentric walls, the space between the Walls being closed at the ends to provide a chamber of large area and small transverse diameter; a base having a diaphragm suitably apertured; a heating agent which may be a gas burner or an oil lamp placed within or below the base; and a primary heating chamber arranged in proximity to the flame and in communication with the annular water space of the radiator. The flame is directed upon this primary heating chamber and being concentrated thereon it acts upon the small quantity of water contained and quickly heats it. The heating of the water in this heating chamber, of course, establishes a circulation and the water may thus in a short space of time be heated to boiling point from the flame of a single gas burner or of an oil lamp.

In the accompanying drawings, Figure l is an elevation showing a gas burner applied to the heater; and Fig. 2 is a sectional elevation showing a lamp in position.

In the drawings, A, B represent the side Walls of an annular heating chamber C, the ends of said chamber being closed by the walls o., b, the lattern provided with a filling opening D.

E represents a base section or support for the radiator proper, said base section4 being preferably in the form of an open ended cy1. inder with a diaphragm or horizontal partition F having a central aperture f therein. The

, section E may be supported by the legs e, the

escape of the heat being through the aperture of the diaphragm.

H represents a primary heating chamber which is composed of the inverted conicalshells I, J, said chamber being in communication with the radiator chamber C through the pipes K, k. This primary heating chamf ber is located in proximity to the flame, and

preferably immediately above the aperture f 6o in the diaphragm F so that the heat of the flame is directed into the hollow base of the heating chamber formed by the lower cone. A small body of water is thus subjected to the direct action of the llame, and is thereby quickly heated,whilethe heat escaping around the edges of said cone, is compelled to pass along the sides thereof by means of the hood L. The heating water flows from this heating chamber into the chamber of the radiator and gives off its heat in a short space of time.

I do not of course limit my invention t-o precise details of construction. The primary heater may be of different form, `the construction shown being adapted to expose va small body of Water tothe heat of the flame by the employment of the confining hood. Good results might be obtained by making the primary heater comparatively iiat and allowing the heat to escape around its edges and pass up along the inner walls of the radiator thus further heating them. Where the conical form is employed, the hood is useful.

The device will be effective when made from light material and of such size as to be readily transported but the parts of the heater may be cast and used as a stationary heater or provided with casters so that it can be moved. It will be found very convenient for use in mild weather in living apartments, sick rooms,

green houses, and similar places where the derstood that any suitable means may be employed. It Will also be understood that the quantity of Water within the radiator may vary and that, if desired, a sufcient degree ot' heat may be employed to generate steam in the radiator.

An ordinary gage is shown applied to the radiator in Fig. l, and the base shell is provided With a hinged door having a sight opening therein. These features are not essential to the invention.

I claim- 1. A heater comprising in combination with a source of heat, such as a gas or oil burner, a radiator consisting of two concentrically arranged Walls joined at their lower ends to form an annular Water chamber and a primary heater arranged in proximity to the source of heat and communicating With the radiator chamber, substantially as described.

2. A heater comprising in combination with a source of heat, such as a gas or oil burner, a metal inclosing shell arranged concentrically thereto, an annular radiator mounted upon the inclosing shell and a primary heater arranged in proximity to the source of heat and communicating with the radiator chamber, substantially as described.

3. In a heater of the class described, the combination with a base having its upper portion formed ot an inclosing metallic shell with a perforated diaphragm therein, a primary heater arranged above the aperture of the diaphragm and an annular radiator' scribed.
