The primary object of the invention is the provision of an efiicient, versatile, and easily portable device of the kind indicated which comprises an assembly composed of a burner, a fuel tank, and means supporting the burner, relative to the tank or to a furnace, for direct space-heating or indirect space-heating, as'in the case of a furnace whose burner has been removed or has been rendered inoperative.
Another important object of the inventon is the provision of a device of the character indicated above, wherein the burner comprises an elongated tube having a fan-forced suction air intake, a gas burner intermediate the ends of the burner tube, and an insulated combustion chamber extending from the burner to an open end of the tube, whereby a forced mixture of air and fuel gas is economically and efiiciently obtained and burned.

FIGURE 8 is a vertical section taken on the line 88 of FIGURE 4.
Referring in detail to the drawings, and first to FIG- URES 1 to 4, the illustrated space heater assembly 10, comprises a normally horizontal, longitudinally elongated metal tubular housing 12, having an open forward end 14, and a rear end wall 16 which is formed with perforations 18. 1
An electric air suction device 20 is concentrically mounted within the housing 12, adjacent to its rear end, and can comprise a motor 22, substantially smaller in diameter than the housing 12, and fixed in concentrically spaced relation thereto, by means of radial arms 24, the arms 24 being fixed to the motor 22, at one end, and, at their other ends, extended through the sidewall 26 of the housing and fixed to a band 28 which is securely circumposed on the housing 12. A suction fan 30 is located close to the perforated rear end wall 16 and is carried by the rearwardly extending shaft 32 of the motor. A suitable motor energizing cord 34 is connected to the motor 22 and extends through a grommet 36, through the housing sidewall.
The band 28 has fixed to its underside, as indicated at 38, a perpendicular downwardly extending housing supporting rod 40, which is formed with a vertical slot 42, in its lower end, for a purpose hereinafter disclosed.
The interior of the housing 12 has welded thereon a liner 44, of heavy gague steel, which extends from the forward end 14 of the housing, to a point approximately midway between the ends of the housing, the rear end of the liner 44 being beveled, as indicated at 46. The
3,306,335 Patented Feb. 28, 1967 forward end of the liner 44 is rounded, as indicated at 48, and is conformably and retainably engaged by an arcuate annular flange 50, on the forward end of the housing.
A burner assembly 52, for such as propane gas, comprises a forwardly and downwardly angled tube 54, which extends down through an opening 56, provided in the top of the housing sidewall 26, and has, on its upper end, above the housing 12, an elbow fitting 58, which has a lateral reduced diameter arm 60, to which is connected, as indicated at 62, a relatively small diameter hose 64. A sleeve 66, fixed to and surrounding the tube 54, is suitably fixed, at its upper end, to the top of the sidewall 26 of the housing 12.
The lower end of the burner assembly tube 54, is threaded as indicated at 68, into the upper end of the upwardly and rearwardly angled arm 70, of an angle fitting 72. The fitting 72 has a horizontal arm 74 which terminates in a concentric reduced diameter jet 76, of relatively short length. The shoulder defined at the forward end of the horizontal arm 74, is fixed as by means of welding 76, to the rear side of a concentric vertical air bafile disc 78. The disc 78 is formed with a central opening 80, through which the arm jet 76 extends.
The arm portion 76 is formed with circumferentially spaced longitudinal grooves 82, which extend to the forward end 84 of the jet 76. A tubular open-ended concentric nozzle 86, longer than the jet 76, is welded thereon, and is formed, in its sidewall, adjacent to the disc 78, with circumferential slots 88, which communicate with the grooves 82, the rear end of the nozzle being abutted with the adjacent side of the disc 78. In an operating example, the nozzle 86 is about A" in diameter, and its outer end is spaced at about /s" from the flame spreader disc 102.
The disc 78 is substantially smaller in diameter than the housing 12 and is concentrically spaced from the housing sidewall 26, at a location adjacent to but spaced rearwardly from the rear end 46 of the liner 44.
A horizontal longitudinal strut 92, preferably in the form of a bolt, extends forwardly from the upper part of the disc 78, through an opening 94 formed therein, with its head 96 engaged with the rear side of the disc, and with a lock nut 98, on the bolt bearing against the forward side of the disc. The strut 92 reaches forwardly beyond the rear end 46 of the liner 44, and at its forward end, is threaded through a nut 100, fixed centrally on the upper end of a circular flame spreader disc 102. The disc 102 is, as shown in FIGURES 1, 3 and 4, smaller in diameter than the air bafile disc 78.
As shown in FIGURE 4, the angle fitting 72 is formed, in its arms and 74, with a continuous gas passage 104, of relatively small diameter, which opens to the forward end of the reduced diameter jet 76.
In operation, with the fan of the suction device 20 in operation, and gas being fed under pressure to the burner assembly, outside air is drawn into the burner housing, through the perforations of the rear end wall 16 of the housing 12, passes forwardly around the burner assembly. As this air passes the air bafile disc 78, it is caused to speed up through the venturi space, defined between the edge of the disc 78 and the sidewall 26 of the housing 12, and passes out through the open forward end of the housing.
Part of the accelerated air stream passes through the holes 88 in the nozzle 86, passes forwardly between the through the forward end of the housing, the resultant flame strikes the flame baffle disc, so as to thereby be concentrated, and passes forwardly, in the space between the disc 102 and the liner 44, the combustion of the gasair mixture being substantially completed within the forward part of the housing 12.
The space heater assembly 10 further comprises a cylindrical propane gas tank 104, having a central upstanding valved fitting 106, on its top, the fitting 106 having a lateral arm 108, to which the hose 69 is connected. The fitting 106 is spacedly surrounded by an upstanding threequarter circular shield 110. The slot 42 of the rod 40 is adapted to be engaged over the upper edge of the shield (110 for supporting the housing 12 across the top of the tank 104, as shown in FIGURE 1.
Where, as shown in FIGURES 5 to 7, the space heater assembly 10, is to be utilized as the heating means for a furnace 112, having a lateral opening 114, the housing 12 is supported on a stand 116, on a level to extend into the furnace, through its opening 114, concentrically with this opening and through the central opening 118 formed in a vertical closure plate 120, which is adapted to be bolted, as indicated at 122, across the opening 114.
The stand 116 comprises circumferentially spaced, downwardly and outwardly angled legs 124, which, at their upper ends, are fixed to the lower end of a standard 126. A vertically adjustable sleeve bracket 128 is circumposed on the standard 126, and is adapted to be secured in adjusted position, by means of a handle-equipped set screw 130. The bracket 128 has a lateral arm 132 having a vertical sleeve 134, on its outer end, adapted to receive the rod 40 of the housing 12, which is held relative to the sleeve 134 by a set screw 136.
The tank 104 as indicated in FIGURE 5, may be located at any suitable place, relative to the housing, and a suitably long hose 64 provided to reach thereto. Or the source of gas under pressure may be located out of the area of the furnace 112, and its hose 34, connected to any suitable gas outlet.
