WILLIAM S. HADAWAY, JR, OF NEW YORK, N. Y.

ELECTRIC HEATING SYSTEM.

Specification of Letters Patent.

Patented June 8, 1915.

Application filed September 7, 1911. Serial No. 648,060.

T 0 all whom it may concern Be it known that I WVILLIAM S. HADAWAY, Jr., a citizen of the United States, residing I at New York, in the county of New York and State 'of New ork, have invented new and useful Improvements in Electric Heating' Systems, of which the followin is a full, clear. concise, and exact description, reference being had to the accompanying drawing, forming a part of this specification.

My invention relates to electric heating systems.

It has among its objects to provide an improved electric heating system,'wherein the heating elements transmits its heat to an object which has the capacity of absorbingand storing the heat and which in turn transmits it to the object or thing to be heated.

It further has among its objects to provide an electric heating system which is particularly adapted to use in connection with heating masses of concrete or tile, such as are used in modern building construction, this material being utilized as a part of the heat-' ing. means.

Other objects and advantages of my improved system will hereinafterappear.

In accordance with a preferred form of my invention, Iso place a heating conductor within thewalls, of a building of concrete, tile -or bther similar construction, that the heat generated by the conductor is communicated to the surfaces of the inclosing material or conducted directly to this material, by which it is absorbed and transmitted to either the atmosphere or an object to warm the same. v

In the accompanying drawings, I have for purposes of illustration shown one form which my invention may assume in practice. invention is not, however, limited to this specific form, but may assume other forms.

In the view of these drawings: Figure 1 shows a sectional view of this form of my invention. Fig. 2 shows a sectional view of one form of heating conductor which may be used.

I ha e illustrated my invention as applied to a section of the wall of a building. It is obvious that this wall may be made of any desired construction, the particular construction shown being for purposes of illustration only.

In a preferred form, my invention is especially adapted for use in connection with bu ldings wherein the walls or partitions are made up of tile or similar hollow construction. My invention is not, however limited to use in connection with such con- 50 'structions .but may be used withconstructions wherein the walls are of a brick or other construction.

In 1, ,a ,tile. construction has beerf shown, thetiles being indicated by the nu- 5 meral 1,, and having openings extending through the same longitudinally. Within these openings are placed electric conductors 2, which may be of bare wire. In a pre ferred form these wires are formed of la resistance material. If desired, I may form them. of a high resistance alloy such. as nickel-chromium or copper-nickel. These conductors are arranged in any desired man; ner within the openings in the tile.

In Fig. 1, I have shown one wire in each, opening, but it is of course obvious that the wire may be bent in any desired shape, and that any desired number of wires may be placed in these openings and arran ed .in any. desirable circuits. Further, if esired,, the wires may be eliectually insulated from each other, as by any suitable insulating composition 3, such as cOncreteQcementor a silica-alumina compound, and the'wires may be held in any suitable position in thetile by means of an insulating compound. v

When current is supplied tothe wires 2, the heat generated by'the passage of the 'cur rent through the wire is radiated from't he wire to those portions of the tile which are not in immediate contact with the wire. The effect of this radiation is to heat the i space within the tile and to transmit this tact with it, such as for instance, the plaster or sizing which forms the inner surface of the walls of a building and will be transmitted through the same to the atmosphere when the atmosphere is at a lower temperature than the wall. Thus it is seen that myv invention may be adapted to use as a heating means for the rooms. of buildings, the wires being laid in the walls through the may be equalized, so that the central station may be producing its maximum output throughout the twenty-four hours of the day. The heat which is transmitted from the conducto' through the walls of the building Will e absorbed by the same, and when the temperature of the room is above the temperature of the walls this heat will not be transmitted to the room but will be stored in the wall, from which it will be dissipated to the room when the temperature of the latter falls below the temperature of the walls. Thus, it is possible to have the walls of the room serve as a low temperature heat reservoir which tend to maintain the temperature of a room at a certain temperature.

In Fig. 2, I have illustrated a sectional view of a heating conductor which may be readily used with my improved system of heating. This conductor itself forms the subject matter of my co-pending application, Serial Number 647,689 filed September 5, 1911. As therein described, this conductor consists of a core 5, of conducting material, preferably of the nature of high resistance material, which'is surrounded by a coating 6 of insulating material, of a heat absorptive character, adapted to take the heat away from the conductor rapidly. A casing 7, surrounds the insulating coating. This casing is preferably formed of a high resistance material, and is one which has the property of readily radiating the heat transany desired length of this conductor in itself forms a complete heatingunit. It is obvious that this conductor may be laid wherever any conductor may be used, and that it may be placed between the walls of a building in the same manner as the uninsulated conductor 2, heretofore described.

While I have in this applicationdescribed my invention specifically I do not wish to be limited to the specific adaptation chosen for the purposes of illustration but wish rather to cover all of the forms of my invention falling within the scope of the patent claims.

What I claim as new and desire to secure by Letters Patent is as follows: I

1. An electric heating means for buildings comprising a wall of heat absorptive hollow tile construction having a plurality of openings therein, electric heating conductors disposed in said openings adjacent the walls thereof and acting as heating mediums to dissipate heat in said openings and to, said tiles whereby said wall *acts as a'low temperature heat reservoir for distributing heat slowly and evenly by radiation.

2. The method .of heating buildings 'of hollow heat absorptive. tile construction which consists in passing electric heating conductors through openings in the tiles and supplying current to said conductors, said conductors acting as a heating means for the.

tiles and the latter acting as a low temperature heat reservoir for distributing the heat to the building.

In witness whereof, I have hereunto 5ub scribed my name in the presence of two witnesses.
