which the supply of gas may be turned on and off without explosions or back-firing and ithout likelihood of the pilot being extin guished.
Objects pertaining to details and economies of my invention will definitely appear from the description to follow. The invention is defined in the claims. V
A structure embodying the features of my invention is clearly illustrated in the accompanying drawing, in which Fig. 1 is a side elevation of a hot air heater embodying the features of my invention, parts being broken away for convenience in illustration.
Fig. 2 is an enlarged fragmentary view partially in vertical section.
Fig. 3 is an enlarged fragmentary view mainly in horizontal section on line 33 0 Fig. 2.
Fig. 4 is av fragmentary vertical section on line H of Fig. 1.
In the accompanying drawing I have illustrated my. improvements as embodied in a hot air furnace, which consists of a casing 1 having an opening 2 at the bottom for the admission of air and discharge openings 3 at the top for the heated air. Within this casing I arrange a combined combustion chamber and radiator unit designated generally by the numeral 4 and comprising a burner chamber portion 5 at the bottom and a radiator portion 7. Thecombustion chamber portion is horizontally elongated with curved walls and is closed with the exception of the air inlet opening 6 in its rear end wall.
The radiator unit 7 opens to the top of the burner chamber.
Within the burner chamber I mount an elongated burner 8 in a plane above the primary air inlet 6 as shown in Fig. 4. I preferably provide balfles 9 which project inwardly from the side walls with their inner edges 10 adjacent to but spaced from the sides of the burner, providing slot-like secondary air inlet openings 11 which effectively direct the secondary air to the burner.
The burner is provided with a mixing tube 1930. Serial in. 464,522.
121which projects from the end wall 13 of .the burner chamber opposite the air inlet opening. This mixing tube is provided with agas nozzle 14 connected to the gas supply pipe 15.. The needle valve 16 is provided for regulating the nozzle. 7
This nozzle and also the valve 16 are mounted in a chambered casting 17 threaded upon the end of the mixing tube. This casting has a stemportion 18 externally threaded to receive the air valve 19, supporting it in operative relation to the end of the casting 17 which, in effect, constitutes a part of the mixing tube. V
On this part 17 I mount a housing 20 constituting a primary air supply chamber which is connected by the conduit 21 to the burner chamber so that the primary air for the burner is drawn from the burner chamber. The door 22 is provided for this housing 20 to afiord'access to the valve 19 and the gas valve 16. g
The pilot 23 is arranged within the burner chamber in operative relation to the burner.
- With this arrangement of parts both the primary and secondary air for the burner enter through the opening 6. The result. is that when the gas supply is cut off from the burner, an explosive mixture is not formed, because the natural draft sets up a current of air upwardly past the sides of the burner and away from the entrance of the conduit 21, thereby preventing the air from entering the mixing'tube and forming an explosive mixture.
In operation, the gas stream issuing from air ceases to flow in the conduit. This isa feature of very decided advantage in gas furnaces for house heating and the like as it avoids the objectionable noise incident to the explosions commonly resulting from shutting off a supply of gas, and also prevents the extinguishing of the pilot by such explosions. When it is taken into consideration that in house heating the gas is frequently turned on and off to control the temperature, these features become highly important.
I have illustrated and described my'improvement in an embodiment which I have found highly satisfactory. I have not attempted to illustrate or describe other embodiments or adaptations as it is believed that this disclosure will enable those skilled in the art to embody or adapt my improvement as may be desired.
Having thus described my invention What I claim as new and desire to secure by Letters Patent is:
1. In a structure of the class described, the combination of a horizontally elongated burner chamber, a radiator opening to the top of said burner chamber, an elongated main burner disposed horizontally within said burner chamber, a pilot burner disposed within said burner chamber in operative relation to said main burner, a mixingtube for said burner projecting through one end wall of the burner chamber, a .gas nozzle operatively associated with said mixing tube, a primary air inlet valve for said mixing tube, a primary air inlet chamber housing mounted on the outer end of said mixing tube and enclosing said primary air inlet valve, said housing being provided with a door affording access to said primary air valve and nozzle, and a primary air conduit opening only to the bottom of said burner chamber and to said housing, said burner chamber having an air inlet in its end wall opposite to said mixing tube.
2. In a structure of the class described, the combination of a horizontally elongated burner chamber, a radiator opening to the top of said burner chamber, an elongated main burner disposed horizontally within said burner chamber, bafiie plates projecting inwardly from the side walls of said burner chamber with their inner edges adjacent to but spaced from the sides of the burner, a pilot burner disposed within said burner chamber in operative relation to said main burner, a mixing tube for said burner projecting through one end wall of the burner chamber, a gas nozzle operatively associated with said mixing tube, a primary air inlet valve for said mixing tube, a primary air inlet chamber housing for said primary air inlet valve, and a primary air conduit connected to said burner chamber and to said housing, said burner chamber having an air inlet remote from the point at which the conduit opens thereto.
3. In a structure of the class described, the combination of a horizontally elongated burner chamber, a radiator opening to the top of said burner chamber, an elongated main burner disposed horizontally within said burner chamber, a pilot burner disposed within said burner chamber in operative relation to said main burner. a mixing tube for said burner projecting through one end wall of the burner chamber, a gas nozzle operatively associated with said mixing tube, a primary air inlet valve for said mixing tube, a primary air inlet chamber housing for said primary air inlet valve, and a primary air conduit connected to said burner chamber and to said housing, said burner chamber having an air inletremote from the point at which the conduit opens thereto.
4. In a structure of the class described, the combination with a burner chamber, of a main burner arranged in said chamber, a pilot operatively associated with said main burner, a mixing tube for said gas burner projecting through a wall of said burner chamber, said mixing tube being provided with a gas nozzle and primary air inlet valve, a housing enclosing said primary air inlet valve, a conduit connecting said housing with said burner chamber, and an air inlet for said burner chamber remote from the point at which said hand.
