application fled l'ebrnary 28, 1982. Serial 10,538,904.

To all whom it may concern:

Be it known that I, Cnon. A. HEAD, a subject of the Kin of England, and a resident of Royal Oa in the count of Oakland and State of Michigan, have invented a new and useful Improvement in Electric Radiators, of which the following is a specification.

My invention relates to electric radiators and its principal ob'ect is to provide a radiator of this type w erein the water supply is retained in a state of evaporation for substantially the entire length of time of operation ofthe radiator.

It is another object of the invention to provide an electric radiator which will radiate a maximum amount of heat in a minimum of time with a minimum supply of electricity.

A further object of the invention is to provide a portable electric radiator wherein the supply of electric current will be automatically cut oil upon total evaporation of the water supply, thus the unnecessary expenditure of electric energy is obviated.

With the preceding and other objects and advantages in mind, the invention consifls in the novel combination of elements, constructions and arrangement of parts and operations to be hereinafter full referred to, claimed and illustrated in t e accompanying drawing, wherein:

Figure 1 is a vertical sectional view of an electric radiator constructed in accordance with my invention,

Fig. 2 is an end elevation of the same, i

Fig. 3 is a topoplan view of the electrical heating unit em died in the invention, and

.Fig. 4 is a vertical sectional view of the same. v, Referring to the drawing in detail wherein similar characters of reference denote similar parts throughout the several views, the numeral 5 designates a vertically disosed cylinder or generating chamber in the ower end of which a cup or water reservoir 6 is threaded. Threaded upon the upper end of the cylinder or generating chamber 5 is a closure 7. Extending horizontally from the cylinder or generating chamber 5 at diametrically opposite points are vertically allned radiating tubes 8 having interior of this cy inder or nerating chamber 5. Communicating witdi the outer ends of the radiating tubes 8 are vertically discommumcation with the posed return pipes 9 whose lower ends reoeive the upper ends of supporting legs 10. In this embodiment of the invention only two sets of radiating tubes 8' are illustratedf It is within the scope of my invention, however, to employ as many sets of these tubes as may be found practical.

My invention provides an improved heat ing unit to vaporize the water contained in the water reservoir 6. This heating unit embodies a rectangular chamber 11 constructed of porcelain or other non-conducting material having a flange 12 at its upper edge which is secured to the bottom of the cup or reservoir 6 by'fastenings 13. Packing 14 is interposed between the flange 12 and bottom of the cup or reservoir 6 to afford a water tight joint between these parts. Arranged in the chamber 11 and spaced from the sides thereof are positive and negative electrodes 15 and 16 respectively, the latter being electrically connected with electricity conductors 17 in circuit with any suitable source of electrical energ not shown. As shown in Fig. 3, each 0 the electrodes 15 and 16 comprises a longitudinal bar 18 from which a plurality of spaced right-angularly disposed fins or plates 19 extend. These plates or fins of these electrodes have intertting engagement and are spaced from each Carried by the cup other. or water reservoir 6 is a laterally extendlng water gage 20 whereby to indicate the liquid level of the contents of the cup or water reservoir.

In the operation of my improved heater the water from the cup or reservoir 6 enters the 5 aces between the fins or'gplates 19 and there y com letes the circuit through the electrodes. e electric current passing through the" water and finding resistance therein, quickly boils and evaporates the same and steam rises in the cylinder or generating chamber 5, thence circulating through the radiating tubes 8. As the water is condensed it passes through the lowermost tubes 8 and flows into the cup or generating chamber 6 to be again vaporized. Should theentire bod of water become totally vaporized the circuit between the electrodes would be'broken. It will be thus seen that the supply of electrical energy will only be consumedwhile the radiator contains water.

It is to be understood that the form of my invention herein shown and described is to be taken as a preferred example of the some, and that various changes in the shape,

size and arrangement of parts may be resorted to Without departing from the spirit of the invention or the scope of the subioined claims.

Having thus described my invention, what I claim as new and desire tosecure and protect by Letters Patent of the United States 1. An electrical heater including a receptacle having an insulated bottom, a pair of electrodes supported on the bottom and each including a bar and spaced right-angularly disposed plates having interfitting engagement and spaced from each other, the 15 circuit between the electrodes being completed by the body of Water contained in the receptacle, and broken upon the exhausreservoir.
