INVENTOR. Pay R FISHER Patented Dec. 16, 1941 BOILER UNIT FOR ELECTRIC STEAM RADIATORS Roy R. Fisher, Detroit, Mich.
Application December 1, 1939, Serial No. 307,025
5 Claims.
This invention relates to electric steam radiators and has particularly to do with a boiler unit for the same.
The type of electric steam radiator under consideration is fully described in copending application, Serial No. 279,775, filed June 19, 1939.
It is an object of the present invention to provide a new type of boiler for an electric steam radiator which is easily constructed, readily installed, and effective in use.
Other objects and features of the invention having to do with details of construction and operation will be set forth in the following description and claims.
In the drawing:
Fig. 1 is a side elevation of the assembly of a radiator showing a portion cut away.
Fig. 2 is a partial perspective of one modification of the boiler unit of the present invention.
Figs. 3 and 4 are sections taken on the lines 3-3 and 4-4, respectively, of Fig. 2.
As shown in the drawing, the radiator consists of a. plurality of sections l joined together at the bottom to form a continuous passageway therethrough. In this passageway in the lower portion of the radiator is a boiler unit l2 which extends through the passageway. Within the boiler unit is a heating element enclosed in a tube l3.
The boiler unit constructed in accordance with the present invention consists of a tubular member which has been formed from a flat rectangular sheet of material such as copper. The longitudinal edges [4 and I5 of the sheet are bent at right angles thereto and positioned adjacent each other at the seam of the tube. When they are positioned together, they form a radial extension longitudinally of the tube. It is necessary to have openings between the boiler and the various section of the radiator. In accordance with the present invention these openings are formed by embossing portions of the edges l4 and I5, as shown at [6 and H, in such a manner that the embossed portions will register to form openings l8 spaced along the seam of the boiler. These openings are spaced at intervals to coincide with the sections of the radiator so that directly below each section there will be an opening from the boiler to the radiator chamber. Suitable openings l 9 and 20 may be provided in the lower portion of the boiler to receive water to be heated.
The edges 14 and I5 are held together by rivets 2|. Other means of fastening the two adjacent portions may be used. It is not necessary that the openings l8 be confined to one for each radiator section since they may be made greater in number or reduced in number and increased in longitudinal extension.
I claim:
1. In an electric steam radiator of the type having spaced hollow radiating sections connected at least at one end and a longitudinally extending heating unit extending through the connecting portions, a boiler unit comprising a tubular member of greater diameter than said heating unit formed of a rectangular sheet of pliable material, the longitudinal edge thereof being bent away from said tube to lie parallel and adjacent to each other radially of said tube, and embossed portions on said edges adapted to register to form tubes at the tube seam, said tube being arranged in said radiator around said heating unit with said seam extending upwardly.
2. In an electric steam radiator of the type having spaced hollow radiating sections connected at least at one end and a longitudinally extending heating unit extending through the connecting portions, a boiler unit comprising a tubular member of greater diameter than and positioned around said heating unit, formed of a rectangular sheet of pliable material, the longitudinal edges of said sheet being joined in parallel relation radial of said tube and formed to provide one or more openings to serve as steam outlets.
3. In an electric steam radiator of the type having spaced hollow radiating sections connected at least at one end and a longitudinally extending heating unit extending through the connecting portions, a boiler unit comprising a tubular member of greater diameter than said heating unit formed of a rectangular sheet of pliable material, the longitudinal edges thereof being bent away from said tube to lie parallel and adjacent to each other radially of said tube, embossed portions on said edges adapted to register to form tubes at the tube seam, said tube being arranged in said radiator around said heating unit with said seam extending upwardly, and means at each side of said embossed portions for holding said edges together to form the seam.
4. In an electric steam radiator of the type having spaced hollow radiating sections connected at least at one end and a longitudinally extending heating unit extending through the connecting portions, a boiler unit comprising a tubular member of greater diameter than said heating unit formed of a rectangular sheet of material, the longitudinal edges thereof being bent away from said tube to lie parallel and adjacent to each other radially of said tube, and one or more embossed portions on one of said edges adapted to cooperate with the other of said edges to form one or more openings at the tube seam, said tube being arranged in said radiator around said heating unit with said seam extending upwardly.
5. In an electric steam radiator of the type having spaced hollow radiating sections connected at least at one end and a longitudinally 10
