The switches 53 and 54 are connected to a A suitable 4 suitable current supply source which may energize the tubes 5| and direct heat out'of either of the grids or grills 52 when desired.

In Figure 7 of the drawings I disclose a heater F which may serve as a space heater or salamander. This heater F includes tubular insulated side walls 55 which are closed at their lower end by an insulated bottom 56. A coneshaped deflector 51 is peripherally secured at 59 to the upper edges of the walls 55. Angularly spaced openings 60 are provided through the wall 55 near the upper extremity thereof so that heat generated within the chamber 6|, defined by the walls 55, the bottom 56 and the top 51, may flow.

A support'62 is provided adjacent the bottom 56 and this support has thereupon a series of spaced sockets 63. Infra-red heat tubes 64 are supported in the sockets 63 and are properly directed to heat the interior of the heater F. I-Ieated air is directed through the apertures 60 and the cone-shaped deflector 5'! also serves as a heat transfer means to heat air above the coneshaped tube 51.

Figure 8 illustrates a liquid heater G of the immersion type embodying my heating unit. The tank 65 is provided, which may or may not be open at its upper end as illustrated. A chamber 66 having vertically extending walls 61, a closed bottom 63 secured to the lower ends of the walls 6'! and a closed top secured to the upper ends of the walls 61, is supported within the outer tank 65. A tubular passage ll extends through the closed top it and extends above the level of the side walls 12 of the tank 65. Wires 13 extend through this tubular passage H into the interior of the chamber 66. A support 14 is secured within the chamber 66 near the top 16 thereof and supports a series of spaced sockets l5. Infra red heat tubes 16 are supported in the sockets 15. These heat tubes 76 are connected in parallel by the wires '13 to a plug '11 which may be secured to any suitable socket. When the tubes 76 are energized heat is created which is directed against the closed bottom 69 acting to heat the interior of the chamber 66 and to heat the liquid surrounding this chamber within the tank 65. v

Figure 9 illustrates a liquid heater H. This heater H includes an outer tank '59 having side walls 80, a closed bottom 8|, and an open top which may be equipped with a cover if desired. A hollow receptacle 82 extends into the tank 19 V and is supported in spaced relation to the bottom 8! thereof by means of legs or supports 83. The inner tank 82 is provided with side walls 64 and a closed bottom 35 attached. thereto. A support 86 is provided near the top of the tank 32 and this support has a series of spaced sockets Bl mounted thereon. The sockets 6'! support infra-red heat bulbs 39 or the like, which are preferably positioned to direct heat downwardly toward the tank bottom 65. The tubes or bulbs 69 are connected in parallel to a pair of conductors which lead to a plug 96 designed for insertion into any electrical socket.

In Figures 10 and 11 of the drawings I disclose a heater J which may be placed in a fire place or the like to produce a decorative appearance as well as to produce heat. The heater J includes a base 9! having a pair of spaced upwardly extending standards 92 thereon. A tubular body 93 similating in outward appearance a log or length of wood is pivotally supported at 94 to the standards 92.

The tubular body 93 has a support 98 therein extending longitudinally of the body 93. The support 98 has a series of spaced sockets 95 thereon which are designed to accommodate infrared heat tubes 96. These tubes are inserted through spaced apertures 91 in the surface of the log so that the heat waves or heat rays generated by the tubes may be directed outwardly in a radial direction.

The various heat tubes are preferably connected in parallel to a suitable source of current supply and when energized produce radiant heat. The direction in which the heat travels may be regulated by pivoting the log body 93 about the aligned pivots 94.

In Figure 12 of the drawings I disclose a heater K which similates a radiator in outward appearance. The radiator K is formed of a series of hollow sections 91 connected together by bolts 99 or other suitable fastening means. A transverse passage I extends through all of the sections 91, forming a common connection between these sections. An aperture I 0| is provided at one end of the radiator and a plug I02 is provided for normally closing this opening. The plug I02 as illustrated in both Figures 12 and 13 has an elongated support I03 connected thereto. A series of spaced upwardly projecting brackets I04 are mounted on the support I03. Sockets I05 are provided on each of the brackets I 04 and infra-red heat tubes I06 are supported in the sockets I05. The heat tubes I06 are preferably connected in parallel to a pair of conductors which extend through the plug I02 to a suitable source of current supply. When energized the bulbs I06 generate heat which heats the entire interior of the hollow sections 91.

In Figure 14 of the drawings I disclose an infrared tube support which may be used in place of the support previously described. In this arrangement I provide a plug I01 similar to the plug I02 and which may be substituted therefor. An elongated support I09, similar to the previously described support I03, is attached to the plug I01. A series of sockets IIO are mounted in spaced relation upon the support I09. Infra-red heat tubes III are mounted in the sockets H0. The heat generated by the tubes I I I is directed in a generally vertical direction, whereas the heat generated by the bulb I06 is projected in a horizontal direction.

In Figures 15 and 16 of the drawings I disclose a. portable heater L which may be moved from room to room if desired. The heater L includes a base panel II2 having upwardly extending spaced parallel sides H3 at either end thereof. A top panel I I4 is connected to the upper ends of the sides H3 and a rear panel H5 is provided on the rear of the frame. A front shield I I6 having a curved under-surface H1 is provided at the upper edge of the enclosure.

A rectangular aperture H9 is provided in the rear panel H5 and an adjustable panel I29 is arranged to fill this aperture. The panel I20 is pivotally supported at I2I to a supporting bracket I22 connected to the rear surface of the panel H5. The pivot joint I2I is a universal connection so that the panel I20 may be pivoted out of a vertical plane or transversely. I

The panel I20 is provided with a series of spaced sockets I23 thereon which are designed to accommodate infra-red heat tubes I24. The heat tubes I24 are arranged in generally parallel relation so that the heat generated thereby may be projected in any desired direction.

It will be noted from the foregoin description that my infra-red heat tubes may be used in numerous ways to produce a heater for liquid or air. The heat is in every case generated from a convenient source of supply of current which actuates infra-red heat tubes.

In accordance with the patent statutes, I have described the principles of construction and operation of my heating system, and while I have endeavored to set forth the best embodiments thereof, I desire to have it understood that these are only illustrative thereof, and that obvious changes may be made within the scope of the following claims without departing from the spirit of my invention.
