HEATING APPARATUS Filed Feb. 7-16, 1929 /Nv K ww l Patented Oct. 14, 1930 UNETED STATES PATENT OFFEQE HEATING APPARATUS Application filed February 16, 1929. Serial No. 340,573.
This invention relates to heating apparatus and has for its object to enable the heating of buildings to be effected in an efficient and sanitary manner. The improved apparatus can be made inexpensively and is of simple construction, and can be manufactured in a readily portable form.
The improved heating apparatus comprises a shallow water container which is of considerable width and height in relation to the depth thereof, and an electrical heating element is arranged in the lower portion of the container.
The liquid remains for an indefinite period within the container as it is not required to circulate through exterior conduits.
The invention makes it possible to construct a radiator having a larger heat radiating surface in comparison with the total bulk and weight of the radiator than is possible with heating arrangements of customary types.
All parts of the surface of the improved radiator are readily accessible and are so shaped that accumulation of dust is largely avoided, and such dust as may collect can be quickly and completely removed.
The invention consists in the method and construction and arrangement of parts hereinafter described and more particularly pointed out in the appended claim.
Referring now to the accompanying drawings, which illustrate, by way of example, one convenient embodiment of the invention,
Figure 1 is a front elevation partially in section, and
Figure 2 is a section on line 22 of Figure 1.
The improved heater comprises a rectangular, sheet metal water container having a front wall 1 and a rear wall 2. The walls 1 and 2 are spaced apart a distance which is preferably short in relation to the length and height of the container. For example, if the length of the container is two feet and the height is fifteen inches, the depth, or space between the front and rear walls may conveniently be about one inch.
The marginal portions of the walls 1 and 2 may be pressed into semicircular cross section as at 8, and the outer edges of the walls are preferably flanged as at a, the flanges be ing connected together, as by welding. A substantially cylindrical trough thus surrounds and communicates with the central or rectangular portion of the container.
Hollow cylindrical extensions 5, 6, 7 and 8 are preferably formed at the corners of the container. These extensions, in which internally screw-threaded bushings 9 are secured, are in axial alignment with the cylindrical enlargements at the upper and lower edges of the container. A filling plug 10 is screwed into the bushing in extension 5, A and a drain plug 11 into the bushing in extension 7. A safety valve 12 is mounted in the bushing in extension 6, and an electric heating element 13 in the bushing in extension 8.
' The element 13 is of any type capable of operating while immersed in liquid and preferably extends along the greater part of the length of the circular enlargement at the bottom of the container. Any suitable electrical supply cord 14, fitted with a plug 15 for a wall socket or other electrical outlet, is connected to the element 13, and a switch is indicated at 16.
The walls 1 and 2 are preferably formed with depressions to increase their radiating n surface and to deflect the liquid in the con tainer and cause it to circulate along tortuous paths. As shown in the drawings these depressions consist of several rows of spherical concavities 17 onthe front wall and similar concavities 18 on the rear wall. Preferably the rows of concavities are staggered as shown, and the concavities 17 register with the concavities 18. It is preferred to provide a small space 19 between the adjacent surfaces of a majority of the concavities 17 and 18. One or more, however, may be connected by spot-welding or otherwise, as indicated on one of the pairs of concavities at 20.
Suitable feet such as 21 may be provided if the radiator is to stand on the floor, or brackets. such as 22, may be carried by the rear wall 2 when it is desired to hang the radiator from nails on a wall of a room. A small drain valve 23 may be provided at any desired position.
- radiator is designed.

Water is introduced into the container to about the level of the valve 23 by removing the plug 10, and the plug 10 is then replaced.
By operating the switch 16 the element 8 5 is turned on and the temperature of the water is raised in the lower part of the container. The space above the levelolt valve 23 allows for the expansion ofthe water. The heated water ascends in circuitous paths ow- 19 ing to the restrictions formed by the concavities17 and 18, and is replaced by the upper, cold water which is heated in turn until the entire body of liquid iii the containerihas been raised to the temperature for which the The radiator is of very simple construction and is readily portable. It is very efficient, in that it is capable of great heat radiation having regard to the electrical power 20 required to operate it, and moreover needs practically no attention, and as its outer surfaces .are all relatively smooth and readily accessible it is easily and quickly cleaned.
It will be understood that any modification's'jof shape, dimensions or construction within the scope of the appended claim may be made'without departing from the spirit of the invention. a V r I claim:
, so In a portable radiator, a water container comprising front and rear walls of sheet metal whichare uniformly spaced from each v otherover the greater part of their surfaces,
said walls having registering pairs of concavities arranged to restrict the internal space of the container at a number of points, certain of said pairs of concavities 'beingconnected together, while the remainder, are
, slightly separated, the container being rec- 40 tangular and the walls being formed to provide hollow, substantially cylindrical enlargements along the four edges of the container, the horizontal enlargements being extended laterally beyond the vertical enlargements and provided with screw threaded bushings, a safety valve screwed into one of the upper bushings, an electrical heating element projecting into the container through one of the lower bushings, plugs screwed into the remaining two bushings, and a drain valve below the top of the container.
In testimony whereof I have affixed my signature. 7
