UNITED STATES PATENT OFFICE.

ELECTRIC RADIATOR.

Application filed April 18, 1927. Serial No. 183,516.

My invention relates to radiators and more particularly to the type known as electric radiators.

It has for its objects to provide a more inexpensive radiation than has heretofore been had; to provide convenient radiation means easily adaptable for portable use; to provide a new and novel combination embodying electrical conduit encased in pow- 1 dered substance, producing maximum heat storage with minimum current consuniption and extended heat radiation over a pro longed period after the electrical current has been shut off; to provide a new and novel combination embodying a meta-l radiator case adaptable as a container for generating and radiating electrical heat, and to provide the various other advantages and results made evident from the following specification.

I accomplish the objects of my invention as shown in the accompanying drawings, which form a part of this specitication, and in which Figure l shows an electrical resistance element, utilized in and encased by each of the radiator units shownin Figure 2, one or more of which units are connected to furnish a completed radiator of any given size. Figure 3 shows a top view of my assembled radiator. Figure e shows an end view thereof.

Referring again to the drawings (Figure l), A shows the joint holding rod and ref turn electrical current conduit adapted to suppoit the resistance element in position within the radiator unit. B shows an iusulation plate attached by the nuts C and D to the threaded end of the rod A opposite its end (also threaded) carryingthe return wire to the source of electrical energy. to which it is attached by the nuts K and L.

E shows the insulation material, preferably porcelain, separating the rod A from the heating coil F, one end of which is attached to the rod A by the nuts C andG, and its opposite end attached to the contact H which encircles the insulation E. To the Contact H is connected the lead wire I from the source of electrica-i energy.

Referring again to Figure 2, IWI shows the radiator units, a portion of one being cut away to disclose the electrical resistance element positioned therein. N shows the cy- .iindrical connection joining the radiator units, also serving as a wire conduit and switch container. as disclosed in its cut awa Y portions. O shows a powdered substance of heat retaining qualities with which the radiator units are iilled, the resistance element being embedded therein.

Referring again to Figure 4, P shows the position of the controlling switch, by means of which the electrical current is turned on and off.

Similar letters of reference refer to similar parts throughout the various views.

iVhile I have illustrated and described a preferred construction for carrying my invention into eitect, this is capable of variation or modification wit-hout departing from the spirit of the invention. I therefore do not wish to be limited to the exact details of construction herein set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claim.

Havin' thus described my invention I claim as new and desiie to secure by Letters Patent of the United States of America:

In an electrical heating apparatus, the combination of a plurality of resistance elements each having a supporting rod and an insulating plate on the end of each rod, a plurality of vertical, hollow radiator units each of which is adapted to receive a resistance element therein, said insulating plates adapted. to position said elements therewithin, a plurality of connecting conduits one arranged between and at the tops ot each of the radiator rinitis and adapted to receive the wiring connections from the rods and coils of the several resistance elements, and an end conduit section carrying a switch and to which all of said wires are led for the purpose deiined.

In testimony whereof, I aiiix my signature.

AUGUSTUS M. NICKERSON
