GAS HEATER Filed Aug. 1s, 1941 nnu 79 HarzzyET/wmong Patented Dec. .1.4, 1943 ariane GAS HEATER Application August 13, 1941, Serial No. liilfiiili 2 Claims.

This invention relates to room or space heaters of the type employing a heat reflecting bowl and a radiant unit which is caused to glow as a result of combustion of natural or artificial gas.

One of the objects of the invention is to provide a novel burner unit including a practical and eicient mounting for a plurality of spaced burner discs as well as the radiant. That is to say, the construction employed provides means for readily mounting the burner discs in proper relation in the burner and utilizing the radiant and its supporting means for holding the discs in place. This feature is of special importance because it facilitates the initial assembly or subsequent renewal of the burner discs which are preferably of different size mesh, depending upon whether the burner is to be used with natural or artificial gas or a mixture of such gases. Moreover, the use of a plurality of spaced screens eliminates noise in the operation of the burner, and also provides for an extremely even distribution of the gas over the outside of the radiant regardless of the axial disposition of the radiant so that the burner will function eiiciently in any position between the vertical and horizontal. At the same time these screens or burner discs eliminate llame sputtering and prevent flashback of the burner flame upon ignition or the turning down of gas pressure. It may also be pointed out that the use of a plurality of screens permits the injection of more air for combustion into the burner and produces a shorter flame than would otherwise be obtained with a single screen.

A further object is to provide a gas heater construction lending itself to standard manufacturing procedure and which is substantial, reliable, and eiiioient in use.

With the above and other objects in view, which will more readily appear as the nature of the invention is better understood, the same consists in the novel construction, combination, and arrangement of parts hereinafter more fully described, illustrated and claimed.

A preferred and practical embodiment of the invention is shown in the accompanying drawing, in which:

Figure l is a side elevation of the heater, partly in section, embodying the present improvements.

Fig. 2 is an enlarged longitudinal sectional view of the burner unit.

Fig. 3 is a front elevation of the burner unit. Fig. 4 is a rear elevation of the burner unit shown in Fig. 2.

Similar reference characters designate corresponding parts throughout the several figures of the drawing.

According to the embodiment of the invention shown in the drawing, the heater includes in its organization a suitable base, designated generally as I and having adjustable pivot means 2 for supporting a reflector 3 at a selected angle. This reflector is preferably of the parabolic type and is provided substantially at its focal axis with a burner unit designated generally as A and including the radiant B.

The said burner unit preferably includes a mixing tube i which may be of the Venturi type shown and formed at its inlet end 5 with air and gas intake means including the shutter 5 and the gas port l, while the opposite end is provided with a flaring burner head designated generally as 3. The intermediate exterior portion of the tube @i is provided with the offset attaching ears d for securing and supporting the tube axially of the reflector 3. The tube 4 is assembled to the reector 3 by inserting the `shutter end il in an opening in the center of the reflector from the front face thereof, and since the ears 9 are of greater radial extent than the diameter of the shutter end 6 of the tube and consequently larger than the diameter of the opening, the said ears may be attached to the body of the reflector.

The burner head 8 is provided with an end wall IU disposed at right angles to the axis of the tube and may be provided at suitable spaced intervals with a plurality of fastening receiving sockets III. In the example shown, these sockets may be formed in the enlarged ears I2 projecting radially from the outer edge of the burner head, or, if desired, it will of course be understood that the entire mouth of the burner head may be thickened sufciently to provide a basis for the said sockets. The burner head is also provided with an internal annular recess I3 inwardly of the wall I G, the said recess providing an internal shoulder lli. The said recess I3 accommodates a plurality of wire mesh burner discs I5 and I arranged in spaced relation. As will be seen from the drawing, the inner disc I5 abuts against the shoulder I li and the outer disc I6 is spaced from the inner disc by a spacing ring Il. When the discs l5 and I6 are thus assembled in the recess I3, the outer disc I6 is substantially ush with the mouth of the recess I3 and the wall IG.

The tubular radiant designated generally as B is provided at its inner end with a flange IS adapted to engage the wall l at the mouth of the burner head and also overlie and press against the peripheral edge of the outer disc I6.

The said flange I8 is adapted to be engaged by a clamping ring I9 having suitable openings intended to register with the sockets II in the burner head. Fastenings 20 are used for securing the ring I9 to the wall I0 at the mouth of the burner head, the said fastenings passing through the openings in the clampin-g ring and into the sockets in such a way that the ange of the radiant is drawn or pulled toward the Wall I and also pressed into engagement with the outer disc I6 so that the force of the fastenings in being made tight presses and clamps the discs I and I6, and the ring II, tightly in the recess I3. Y

It will thus be apparent that the securing of the radiant B to the mouth of the burner head holds the radiant as Well as the Wire discs in assembled relation to the mixing tube. This arrangement not only facilitates the assembly of I the discs and radiant, but also permits-of their ready removal and interchangeability. That is to say, the construction described makes it possible to readily insert or assemble the discs and the radiant either initially or` in subsequent service so as to utilize Wire mesh or wire gauze of proper size both in the discs and radiant according to the type of gas supplied Where the heater is used. For example, the radiant may be made of sixteen, tvventy, or twenty-four mesh nichrome or inconel Wire, while the outer burner disc I5 maybe made of thirty, twenty-four, twenty or larger mesh material of the same type, and the inner burner disc I5 may be made of sixteen, fourteen or larger mesh, also of the same material.

A heater according to the foregoing .description will burn either natural or artificial gas, or a suitable mixture of the same When supplied with the proper amount of air through the inlet end of the mixing tube. When the proper combustible mixture is supplied to theburner head and ignited, the radiant B Will become incandescent and its heat will be radiated and projected by the reflector 3 to heat the room or other space in which the heater is installed. Because of the Y spaced burner discs I5 and I6, it Will be apparent that the burner will not sputter, flash back, or

prematurely ignite, since the space provided between the discs I5 and I8 maintains the same at a temperature beloW the combustion point, thereby insuring uniform flow of gas for supplying the radiant and also assuring safety in operation.

I claim:

1. A burner unit for gas heaters including a mixing tube having a burner head provided with a front Wall at right angles to the axis of the tube and formed with fastening receiving sockets, a shoulder Within the tube formed by an annular recess leading inwardly from said wall, a pair of wire mesh burner discs of substantially the diameter of the recess separated by a spacing ring and tted Within the recess, a wire mesh radiant including a rtubular body of less diameter than the diameter of the recess and having an out-turned flange at one end thereof which is of less diameter than the said front wall but lof greater diameter than the recess, a clamping ring abutting said flange and overlying said front Wall, and fastenings cooperating With said clamping ring and sockets to press the flange of the radiant into engagement With the discs and in turn press the discs and their spacing ring against the shoulder.

2. A burner unit for gas heaters including a mixing tube having a burner head provided with an internal recess forming an inset shoulder, said recess leading from an outer face of the head and said outer face formed with fastening receiving sockets, a pair of Wire mesh burner discs tted in and enclosedv by said recess, one of said discs engaging said shoulder, a ring Within the recess and having one edge abutting said disc. the second disc of said pair abutting the opposite edge oi said ring, a radiant unit Vhaving an outturned flange at one end abutting the second disc and partially overlying the outer face of the head, a clamping Washer abutting said ange, and fasteners engaging said Washer and entering said sockets to clamp the flange of the radiant to the said outer face of the burner head and also hold the discs in said recess.
