ELECTRIC STEAM HEATER.

' Application. filed March 17, 1926. Serial No. 95,485.

'M )resent invention a ertains enerall I to improvements in the art of portable heaters and specifically to a steam electric heater of this character, as described in the present specification and illustrated in the accom-- panyin g drawings.

The principal object of this invention is to provide a heater of this character including" said sections, there being just sufficient to completely inm'ierse said heating element, before it is energized. When heated, the water surrounding the heating element is converted into steam, which rises and passes out of the top of the steam section of the radiator, into the adjoining condensing section, in which the temperature of the steam is reduced, due to radiation, the same condensing into water, which flows through the small opening at the bottom of this section into the adjoining steam enerating section about the heating element to be againconverted into steam.

Oth er objects and advantages of my invention will become apparent from a perusal of the following specification read in conjun'c tion with the annexed drawing, which is a sectional elevation illustrating an acceptable form of the invention.

The radiator in which I carry my invention into practice is preferably of the ordinary type used in connection with household water heating systems apart from the fact that it is a heating unit per se and is mounted upon casters or the equivalent to facilitate shifting of the same. The radiator comprises, broadly, two principal sections indicated. at A and B, theformer constituting the steam generating section, the latter the steam condensing section. These sections are interconnected at the tops thereof by the passage indicated at C. At the lower extremities where the principal sections A and B are connected together, the intercommunicating opening, such as commonly found in radiator sections of this type, is closed off to a considerable extent by means of a partition plate 3. This partition plate is securelyheld betweenthe meeting parts of the principal sections A and B and extends downwardly'across the intercon'imunicating opening, so as to-leave only a comparatively small opening D through which condensed water in the lower extremity of the 13 sections can pass into the lower extremity oi the A sections, as the water around the heating elements, hereinafter mentioned, in the A sections is converted into steam. The partition plate 3 divides the steam condensing section from the steam generating section in such a manner that steam generated-in the steam generating section cannot pass through the lowerv intercommunicating opening from the steam generating section tothe steam condensing section. Such steam generated must pass up through the sections forming the steam generating sections A, through the passage C to the steam condensing sections 13. The opening 1) is designed for intercommunication of water from the steam condensing section to the steam generating section below the normal water level of these two principal sections. I

A heating element 4 is mounted in the lower part of section A of the radiator, the same being provided with a variable heat switch ,5 for determining the amount of current delivered to the heating element;

In order that the level of the water contained within the radiator may at all times be easilydetermined, I provide a water gage 6. lhe upper end of this water gagev is provided with a flared mouth '7, through which water may be poured into the radiator.

It is of course to be understood'that the radiator may be provided with additional appurtenances necessary for eflicient and safe operation. I

in use, the water contained within the section A of the coil is converted into steam due to energization of the heating element 4. This steam rises and flows through the opening G into section B of the radiator, where the steam is condensed into water due to the lower temperature of this section of the radiator. The water collecting in the bottom of this section of the radiator flows through the small opening D about the heating element 4 and is again converted into steam. Before the heating element 4 is energized, the water level should be such that the water will just com-- pletely cover this heating element- Obviously, in the commercial adaptation of my invention, minor changes in the details of construction may be resorted to with advantage, without departing from the spiritof the invention and the scope of the claim as hereinafter set forth.

What I claim as new is In a device of the character described, comprising a plurality of radiator sections suitably supported together, a portion of said sections comprising a steam generating chamber, the remainder of said sections comprising a steam condensing chamber, an intercommunicating opening to allow steam to pass from the top of said generating chamber to the top of said condensing chamber awatertion retained intermediate the lower meeting walls, of the sections of the portions of the rachator forming said condensing chamber and said generating chamber, said partition extending downwardly across said water-return opening to a deptlr'below the normal water level inthe said generating chamber.

' Iii-testimony whereof, I aflix my signature.
