ELECTRlCALLY-HEATED APPARATUS.
SPECIFICATION forming part of Letters Patent No. 693,144, dated February 1'1, 1902,
. Application iiled April 16, 1901. Serial No. 56,122. (No model.)
To a/ZZ whom it may concern,.-
Beit known that LVIoToR MoNArH, a citizen of the Empire of Austria-Hungary, residing at Vienna, in the Empire of Austria-Hungary, have invented certain new and useful Improvements in Electrically-Heated Apparatus; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
The object of the present invention is an improvement in electrically-heated cookingstoves, heaters, hair-curling irons solderingirons, and the like, which consists in insulating the body forming the heating surface proper from the other parts of the mentionedV apparatus by a poor conductor of heat, so that the passage of heat upon the non-acting parts of the apparatus is prevented as much as possible. a
In the accompanying drawing as an example a cooking-stove is shown in cross-section to illustrate the present invention.
The heating-surface proper, a, is, as the figure shows, not in direct contact with the frame c of the apparatus; but interposed between a and c is a material b, which consists of any non-heatinginsulatingsubstance. The frame c as shown in this instance is provided with an inner ledge or support d inside the vertical plane ofthe upper inner wall of the frame, and a non-heating insulating slab or block b rests on this ledge and fits between said in= ner upper walls of the frame. The upper face of the body l) is hollowed out and contains the plate or body a to ,be heated. In the opposing upper faces of slab b and plate o, are registering grooves, which together form receptacles for the resisting-bodies e, through which the electrical current is passed.
By this arrangement the transmission of heat upon the parts of the apparatus not be# ing designed to give heat is reduced to a minimum, and thus a considerable economy of energy is obtained over the known constructions of'similar apparatus.
I claim- An electrically-heated apparatus comprisL ing a frame c having inner ledges d below the upper edges of its walls, a ynon-heat-conduct ing slab b resting upon said ledges and be tween said walls and hollowed out on its upper surface, and a plate a to be heated resting in the hollow of the slab b, the said slab and plate being provided in their meeting faces, with registering grooves forming receptacles to receive the resisting-bodies e through which to pass the electric current, substantially as described. f
In testimony whereof I affix my signature in presence. of two witnesses.
