8 Claims.
The invention relates to heatand light-radiators combined to form a unitary radiator of mixed rays. This combined radiator is connected with reflecting means which exercises at the same time the two different functions of gathering simultaneously the heat and light rays which emanate from the heat and light radiators and of projecting the two concentric ray-cones outwardly to their spot of action. The light 10 sources may be of different nature i. e. glowlamps, vapour of mercury, blue light and red light, lamps of precious gas and others. The heat radiation is preferably carried through by infra.- red rays. A lightand heat radiator of said combination is constructed in such a manner that spirals of heating wire or sheet metals are arranged on the outside of a body of fire-brick, in the interior or on the open brim or outwardly of which there is provided a socket for the desired intercalation 0; an incandescent lamp, mercury lamp or of another source of light. The lamp holder which is mounted in the interior of the body of fire brick is separated from the inner wall of the latter by an intermediate space filled with air or by a layer of asbestos to keep off the heat. The reflector for the concentration of both rays consists of a combination of two parts, namely, a parabolic reflector for the heat rays and a reflector for the light rays. The reflector part for the rays of light consists of single shining annular surfaces, set ofl one after the other inwardly. The source of heat or light rays is preferably arranged in the common axis of the reflector parts.
The drawings illustrate one embodiment of the invention. Fig. 1 shows a section of the heat and light radiator; Fig. 2 a top plan thereof with certain parts partly removed; and Figures 3 and 4 represent respectively an elevation and top plan of the reflector with a combination of inset lightand heat radiators. The combined lightand heat radiator according to the invention consists of a conical body of fire brick or porcelain. I serving to support the heating spirals and of a lamp socket 5 arranged in. the middle of the interior of the said conical body or on the outside of same. The lamp holder 5 is fastened to the body of porcelain by four supporting fiatiron pieces 3.
For the purpose of keeping off the rays from the heating body to which they emanate from the radiating lamp and to direct them to the proper point of application, there is arranged a special reflector 4. To keep off the heat pro- 55 duced by the infra-red rays from the radiating In Austria July 14, 1931 lamp and lamp holder, the wall of the flre brick body I is separated by a layer of asbestos or of like material 2 and by the space of air a. The layer of asbestos 2 may also be omitted.
Too much heating of the space of air a is prevented by provision of circulation. The hollow space a is connected at both ends with the outer air. At the upper end the conical reflector 4 is .not mounted tightly but forms a free slit b over the radiating body. At the lower end of the mantle of fire brick I there are set in two or more little tubes 1 directed against the surfaces of the reflector. By bores (slits or holes) in the main reflector which are arranged opposite the ends of said tubes, the cold air from behind the reflector is enabled to enter. The lower wall of the body of fire brick with the tubes I may also be omitted. The current of air therefore enters from the back of the reflector through the holes 8 into the intermediate space a and passes through the slit b into the heated space of air at the frontside of the special reflector 4.
The body of fire brick may also have of course a cylindrical or other shape and instead of the spiral heater there may also be used a heating metal sheet. The reflector, which mixes the light rays emanating from the lamp 9 and the heating rays emanating from the heating wire I0, consists of the smaller inner reflector portion Na and of the joining otherwise shaped greater reflector portion IIb. As may be perceived from the Figures 1 and 3 the radiating bodies are arranged in the axis of the reflector. The mirror surface of the reflector I I a surrounds the heating body of fire brick spherically or parabolically and projects a bunch of parallel rays outwardly. The part I lb of the reflector, which surrounds the lamp, has to gather, however, the rays emanating from the light source 9 and to project them also in axial direction so that the lightand heat rays are mixed intensively.
The part of the reflector which surrounds the lamp is specially shaped as it consists of a number of annular mirror surfaces connected to each other by small steps set oif in such manner that the slope of said surfaces diminishes constantly according to the parabolic curve d. The purpose of this construction is to cause by a smaller and, in consequence of the steps, more solid reflector, precisely the same mirror-effect or the same direction of rays as by an ordinary relatively larger and deeper reflector.
For the regulation of the heat radiation there are cut out holes (e. g. six) in the reflector Ila, which may be opened or closed by a regulating Cir device. This regulating device consists of a mirror shell l2 laid at the outside and upon the reflector part Hat and said mirror shell is provided also with six holes of the same size. The regulating shell is slidable by a handle 53 so that the holes 01 and 02 can be covered more or less one by the other. This device not only enables one to diminish or enlarge the mirror surface destined for the heat reflection but at the same time enables one to reduce or increase the degree of air cooling. The absolute intensity of the light radiation from the radiation body 9 is not impaired by the regulation of heat, so that while the light intensity remains constant, the heat radiation can be reduced. The movement of the shell I2 is limited by pins sliding in slots I4 of the regulating shell l2.
By the arrangement of this reflector the rays emanating from the heat and light source are mixed at the same time in such a manner, that the spot or location to be subjected to the rays is really exposed to the desired heat as well as to the light radiation, For the purpose of enabling a desired composition of rays for a given case of illness, any desired light or lamp is screwed into the body of the long wave radiator; for instance the infra-red readiator is combined with a glow-lamp of mercury vapour, so that uniformly mixed radiations of ultra-shortand ultra-long waves are sent simultaneously and centrally to the sick part of the body.
What I claim is:
1. In a combined heat and light radiator, the combination of a refractory body having centrally thereof a chamber, an electrical heat producing element carried by said refractory body, a light holder mounted within said chamber and so disposed therein as to define an insulating space between the said holder and the refractory body, said chamber having an opening therein to enable a light to be engaged with said light holder.
