To all whom it may concern:
Be it ltnown that limitant A. LYNCH, citizen of the United States, residing in the city of Los Angeles, county of Los Angeles, i
and State of California, have invented new and useful Improvements in Gaslini-ilaces, of which the following is a specification.
The object of my invention is to provide a gas furnace with large heating capacity and to carry olf the fumes or carbon monoxid and prevent the same from commingling with the air that is used for heating purposes, and at the same time to utilize the heat usually escaping with such fumes. l accomplish this object by the furnace described herein and illustrated` in the accompanying drawings in which Figure 1 is a side elevation partly in section and partly broken away, of my im proved furnace. Fig. Q is a section ou the line 2-2 of Fig. 1.
ln the drawings 5 is the external casing which is preferably of sheet metal and preferably (piadrangular. tpening from the top of this casing are the usual service pipes ti which carry the heated air to the place of use. There may be as many of these service pipes as are desired7 the number depending upon the capacity of the furnace. rit the bottom of the casing on the sides thereof are the air inlet openings 7 through which the air to be heated passes. At one side above the air inlet the outer casing is provided with a door 8 to provide additional facility for inspecting the interior of the casing. There may be a door on the other side. The casing is also provided with a lining 9 which is connected to and held separated from the casing by brackets 10 thereby providing an air flue 11 between the exterior casing and the lining.
Projecting through one end of the casing are the burners 12, of which there may be any desired number, I have shown four as I consider that number desirable for an ordinary sized furnace, and they are of any approved construction, and are provided with the usual pilot lights, not shown. These burners run longitudinally and close to the back plates 13 of what may be termed the burner chamber. These plates are secured to the end walls 1 4. and 15. On the front of these back plates are sheets of asbestos 16 which hold the flame in the usual manner of gas furnaces. Below the burners these back plates curve outwardly and form supports for the polished reflectors 17 which deflecty the rays of heat when the burner .is in operation.
1S are the side walls and 19 the bottom of the burner chamber'.
The end walls 141; and 15 of the burner chamber are extended upwardly and form the end walls of what may be denominated the fume chamber 20. The lower portion or throat 21 of the fume chamber is of the same size as the lower portion of the burner chan'iber, as best shown in F 2. Above the. throat the fume chamber widens and in the widened portion is provided with a plurality of air tubes Q9 through which a portion of the air pass s on its way to the service pipes. illithin the fume chamber is a il-shaped deflector Q3 which detlects the fumes that pass into the chamber around the outer air tubes ln one end of the fume chamber is an outlet port which opens into an outlet pipe to which the vent pipe, not shown, may be connected to carry the fumes outside the building. or to a chimney.
y this construction th\ air to be heated passes directly in front of the burners and is subjected to the direct waves of heat produced thereby. The fumes, or carbon monoxid and a portion of the heated air passes upwardly through the opening between the back plate and the bottom of the throat of the fume chamber, and is deflected upwardly around the air tubes and then passes downwardly and out of the fume chamber. ln their passage through the fume chamber these gases heat the exterior walls thereof as well as the walls of the air tubes which pass therethrough, thus giving additional radiating surface and etliciency to the furnace. It will be observed that the air is broken up into a large number of ascending currents, and it is thereby subjected to the action of a large radiating surface whereby it becomes highly heated. The outer casing is preferably quadrangular and the burners are preferably so arranged thatthe greater portion of the air to be heated for use passes through vertical llues.
Having described my invention what I claim is 1. An improved gas heater comprising an outer casing of sheet metal having a pipe connected to the top to carry olf the heated air, and having air inlets at the bottom in the sides thereof; a burner projecting into said casing and across the lower portion thereof; a back plate behind said burner ini thereof; baclr plates behind said burners inclined to project above and in front ot the vertical plane ot the burner; a tume Chamber extending upwardly above said baci;
plate having the top portion above the back plate projecting beyond the vertical plane ot' the back plate with an opening into the fume chamber above the back plate and an outlet passage at one end; and a plurality of air heating tubes extending vertically through the projecting portions of said fume chamber.
2. An improved gas heater comprising an outer casing ot sheet metal having a pipe or pipes connected to the top thereof to Carry ott the heated air; a lining separated 'from the casing to form an air tlue therebetween, said lining extending around the side and end walls of the casing, except at the top and the bottom; a plurality of gas burners projecting into said casing across the lower portion thereof; back plates behind said burners inclined to project above and in front of the vertical plane ot' the burners; a fume chamber extending upwardly having an outlet passage at one end near the center thereof; said fume chamber being situate above said back plates and overhanging them and having an opening in the bottom t-hereorP above the back plates to receive the products ot combustion; and a plurality ot air heating tubes extending through the projecting portions otl said itunie chamber.
An improved gas heater comprising an outer quadranglar casing ot' sheet metal having pipes connected to the top thereot to carry oit the heated air; a lining extending around the side and endwalls of the casing except at the top and bottom and separated from the casing to form an air line therebetween; a plurality of gas burners projecting into said casing across the lower portion clined to project above and in front ot' the vertical plane ot the burners; asbestos on said bach plates at and above said burners; a fume chamber extending upwar lly above said back plates having an outlet passage at one end near the top thereof and having an inlet at the bottom thereor", said inlet being wider than the distance between the top edges of said baclr plates; a plurality ot vertical air heating tubes extending through the outer portions of said fume chamber; and a detlector in said fume chamber.
el. An outer casing having air inlets at the bottom thereof, and air outlets at the top thereof; burners within the outer casing above tlie plane of the air inlets; deflecting plates bach of the burners, said plates projecting at the top thereof beyond the vertical plane of the burners and terminating above the burners; a fume chamber above and projecting beyond the back plates and having an opening in the bottom thereof a little larger than the opening between the top edges of the back plates and having an outlet portabove said bottom opening; vertical tlues extending through the portion of the fume chamber which projects beyond the baclr plates; and a detlector in said fume chamber separating the bottom opening trom the outlet port, said deiiector extending upwardly and mitavardlu'Y and terminating at the outer vertical tubes a distance troni the top' ot the chamber.
ln witness that l claim the foregoing I have hereunto subscribed my name this 5th day of lvlarch 1909.
