HARRINGTON, OF BUFFALO, NEIV YORK, ASSIGNORS 'IO EMILIE F. HARRINGTON, OF BUFFALO, NEW YORK GAS BURNING HEATER Application filed May 31,

This invention relates generally to improvements in gas burning heaters such as are used in homes.

Its chief object is to so design the heater that the poisonous carbon monoxide gases emitted from the products of combustion are decomposed or reduced to a non-poisonous and harmless gas.

Another ob] ect of the invention is the provision of a flueless heater of this character which is simple and inexpensive in construction and efficient in operation, and whose parts are so organized and arranged as to afford an effective circulation of the air and products of combustion to derive a maximum of heat radiation.

In the accompanying drawing Figure 1 is a face view of a gas heater constructed in accordance with my invention. Figure 2 is an enlarged transverse vertical section thereof. Figure 3 is a sectional view, similarto Figure 2, showing a slightly modified form of the invention.

Similar characters of reference indicate corresponding parts throughout the several views.

While our invention is applicable to various heating devices from which toxic carbon monoxide gas escapes, it has been shown, by way of example, in connection with a domestic, radiant or open front type of gas heater including a suitable frame 10, a burner 11 and incandescent or radiant tubes 12 disposed vertically over the burner-jets. Extending along the rear sides of the radiant tubes is a vertically-disposel refractory wall 13 which preferably terminates at its upper endand over the tubes in a forwardly and downwardly facing extension or deflector 14. An outlet or opening 15 is formed adjacent the upper end of this wall for the discharge of the products of combustion emitted from the burner.

Disposed at the rear side of the heater in spaced relation to the refractory wall 13 is a second wall 16 which forms with the latter an air intake passage or chamber 17 for introducing atmospheric air into intimate relation with the products of combustion escaping from the burner. This second wall is 1930. Serial No. 458,858.

preferably inclined toward the refractory wall, in the manner shown in Figure 2, to provide an upwardly converging air passage which results in an increased velocity of the air as it travels through said passage. Adjacent its upper end and opposite the outlet 15 in the refractory Wall, the second wall 16 has an outlet 18 through which both the products of combustion and atmospheric air are adapted to escape. In addition to the air admitted through the passage 17 a secondary supply is also admitted over the upper ends of the radiant tubes 12 and directed into the upper portion of said passage by the refractory wall extension 14.

A flue or conduit 19 extends from the rear wall 16 for receiving the products of combustion and air discharged from the outlet 18 therein. This conduit contains a catalyzing agent which may be in the form of screens 20 disposed in spaced relation and made of copper or other catalytic material. As shown from the burners are discharged into the conduit 19 into intimate contact with the catalyzing agent, which, in the presence of the oxygen of the air drawn through the air intake passage 17 effectively promotes a union of the carbon monoxide, present in the combustion products, and oxygen to form the relatively harmless carbon dioxide gas, thereby eliminating the present dangers coincident with the use of domestic gas heaters and similar heating apparatus. fective circulation of warm air is provided for by the passage 17 and conduit 19 and a maximum of heat radiation is obtained.

We claim as our invention 1. In a gas heater of the character clescribed, the combination of a wall applied to the rear side of the heater in spaced relation thereto to provide an air intake passage extending upwardly alongside and behind the heater elements and provided adjacent its Furthermore, an efupper end with an outlet for the discharge of air admitted to said passage and the products of combustion emitted from the heater, and a conduit containing a catalyst applied to said wall and in communication with said passage outlet. a v

2. In a gas heater ofthe'character described, the combination of a wall applied to the rear side of the heater in spaced relation thereto to provide an upwardly tapering air intake passage extending alongside and behind the heater elements, and a conduit containing a catalyst projecting "outwardly from said wall and in communication at its inlet end with said air intake passage and at its outlet end with the atmosphere,the productsof combustion emitted. fromthe heater and the oxygen of the air admitted through said passage being discharged through said conduit to intimately contact with the catalyst therein and reduce thepoisonous gases contained in products'of combustion to non-poisonous gases.

3. In a gas heater of the character described, the combination of a wall applied to the rear side of the heater'in spaced relation. thereto to provide an upwardly tapering air intake passage extending alongside and behind the heater elements, and a conduit containing a catalyst projecting outwardly from said wall and in communication at its inlet end with said airintake passage and at wardly facing deflector extending over the upper ends of said tubes, a second wall spaced from said refractory wall'to form an air intake passage and having an outlet therein substantially opposite said refractory wall outlet, and a conduit containing a catalyst in communication with the outlet of said second wall and through which the air introduced through said intake passage and the products of combustion emitted from the'heater are adapted to travel.
