wn'rnn HEATER.

7 Application filed March 9, 1921. Serial No. 450,887.-

Toall whom it may concern Be it known that I, JACOB HENRv BECK- MAN, a citizen of the United States, residing at Oakland, in the county of Alameda and State of California, have invented new and useful Improvements in Water Heaters, of which the following is a specification;

This invention relates to a water heater, and particularly pertains to a heating unit and electric heating means therefor.

It is the principal object of the present invention to provide a water heater adapted tobe readily constructed to form separate heating units and to be readily heated by self-contained electric heating means.

The present invention contemplates the use of a radiator, through which water is circulating, said circulation being maintained by electric heating means contained within the unit, the heating element of said means being sectionized so that a decided degree of heat may be established and maintained within the radiator.

The invention is illustrated b way of en ample in the accompanying rawings, in

which Figure 1 is a view in elevation showing the completeheater with parts broken away to more clearly disclose one-of the heating Fig. 3 is an enlarged view in section and elevation showing one of the heating elements, and particularly disclosing the core construction.

Figure 4 is a central transverse sectional view of the heating element illustrated in Figure 3.

eferring more particularly to the draw ings, 10 indicates a water radiator. This radiator is of common construction, being 1 ing na formed with a plurality of sections 11 in-" tercommunicating at top and bottom. The radiator is filled with water which circulates through the sections thereof, without leavthe heater except when excessive interthe steam may blow off through a safety valve 12. I

A irculating pi per end of the ra iator and extends downwardly to communicate with a heat dome 14. This dome is formed at'the top of a heating drum 15, which member is disposed at one pressures are produced, at which time 13 is secured to the up-.

The heating unlt comprises the drum 15 which is substantially cylindrical in formatlon and is intended to receive a plurality of heatlng elements 17. These elements are preferably arranged in diagonal and staggered relation to each other, thus provid ,ing obstructions against which the upwardly circulating water may strike and be thoroughly distributed around the various heating elements.

Reference being had to Figs. 3 and 4, it will be seen that each of the heating elements comprises an outer cylindrical shell 18 -\preferably formed of thin copper and within which a core 19 is positioned. This core is molded from dielectric material, and

fits within the shell. The core is substantially spool shaped, having one end 20 conforming to the closed end of the shell, and its other end 21 enlarged to provide a bolting flange by which the core is secured to the drum on the heater. The shell 18 is formed with an outwardly. flaring flange 22, which is disposedlbetween the bolting flange and the outer face of the heater, thus making it possible to rigidly secure the assembled heating unit in a detachable position relative to the drum.

The body portion of the core between the heads is of reduced diameter and at its opposite ends is formed with a plurality of radially extending fingers 23. These fingers are inclined toward the ends of the head and cooperate with inclined faces formed at the backs of the heads on both ends of the purpose of ventilation an enlarged central opening 27 is formed directly through the core and also through the closedend of the shell 18. Attention is directed to the fact that this closed end of the shell projects no t through the side wall oi: the heating drum upon the opposite side from that to which the bolting flange is secured. 1

In order to maketh'e heater applicable for various temperatures required, the heat in elements are electrically connected with a three-way switch 28, by which one or any i plurality of the elements maybe thrown into a circuit and the temperature of the water thus controlled. A fuse box 29 is conveniently secured to the side of the drum 15. The temperature of the water may be automatically controlled by a suitable thermostat diagrammatically indicated at 30.

In operation of the present invention the heater is assembled as shown in Fig. 1, after i made.

*stat 30. In the event that an excessive heat is attained the safety valve 12 will blow ofl permitting the radiator to be vented. It will thus be seen that the heater here disclosed, while simple in its construction and operation, provides means whereby a heating radiator may be economically maintained at a desired temperature by readily controlled electrical means.

While I have shown the preferred form of my invention, as now known to me, it will be understood that various changes in the combination, construction, and arrangement of parts mi ht be made by those skilled in the art, wit out departing from the spirit of the invention, as claimed.

. Having thus described my invention, what I claim and desire to secure by Letters Patent is:

1. In an electric heating device a heating 1 unit comprisingathin metal shell being substantially closed 'at one end and formed at ltS oppositeend with an out-turned flange,

' a core of dielectric material mounted within said shell, said core being spool-shaped to provide heads fittin ends of the shell, one head being enlarged to .form a flange around the opened end of. the

shell and against which the flange of the shell may seat whereby the unit may be detachably secured in position, and an electric heatlng element supported on said core.

2. A core for an electric heating element formed of dielectric material and comprising a substantially spool-shaped member around the cylindricalbody portion of which, and

at the opposite ends thereof, a pluralit of.

radial wire supporting arms are forms member of dielectric unaterial, oppositely and outwardly inclined radial within the opposite at the opposite ends of the structure.

4. A core .for electric heating elements. comprising a substantially spool-shaped member of dielectric material, sets of oppositely and outwardly inclined radial arms formed integral with the core near its opposite ends, and over which resistance wire may be wound. a

5. A core for electric 'heating elements. comprising a substantially spool-shaped arms'formed integral with the core near its opposite ends and over which resistange wire may be wound, one end ofsaid core being enlarged to form a fastening flange therefor.

6. A core for electric. heating elements comprising a cylindrical member of dielectric material having enlarged heads on each end, radial outwardly extendin fingers on the cylindrical member spaced from the heads and arranged in staggered relation to each other.

7. A core for electric heating elements comprising a cylindrical member of dielectric material having enlarged heads on each end, a casing for the core having a rounded end, oneof the said heads fitting. within and conforming to the said rounded ends of the casing.

8. A core for electric heating elements sets of comprising a cylindrical member, radial outwardly extending fingers on the cylindrical member arranged in staggered relation to each other.

9'. A .core for electric heating elements comprising a cylindrical member having enlarged heads on each end, rzidiah'fingers carried by the cylindrical member and arranged in staggered relation to each other, one of the said enlarged heads having openings therein to receive a resistance element.

10. A core for "electric heating elementscomprising a spool-shaped member, around the cylindrical portion of which a plurality of radial supporting arms 'areformed, the

said core having a ventilating passage;there-..'

through.

11. A heating devicecomprising a drum,

a plurality of heating elements in the drum each heating element comprising a spoolshaped core having a ventilating passage therein, a casing extending through the! drum and receiving the core, the said casing having an opening therein registering with the ventilating passage in the core.
