STOVE CONSTRUCTION.

Application filed November 29, 1926. ,Serial No. 151,410.

This invention relates to a hot air circulating heater combined with a gas stove of the kitchen range type.

The main objects of this invention are to provide a circulating heater which will warm up the air in the room in which it is placed at the same time as it heats the top or cooking plate of the stove.

An illustrative embodiment of this invention is shown in the accompanying drawings,

in which Fig. 1 is a side elevation of a gas range having this improved form of circulating heater.

Fig. 2 is a front elevation of one end of the same, showing the discharge end of the air heater.

Fig.3 is a plan view of the burner showing 'its position in the burner compartment, taken on the line 33 of Fig.5.

Fig. 4 is a section taken on the line 4-4 of Fig. 2.

Fig. 5 is a section taken on the line 5 5 of Fig. 4.

Fig. 6 is a section taken on the line 66 of Fig. 5.

1n the construction shown in the drawings, a gas range 1 is shown provided with a burner compartment 2, formed by housing walls which comprise a front wall 3, a back wall 4, a top plate 5, bottom 6, and. sides 7 and 8. This burner compartment is substantially rectangular in shape, and has extending therethrough from the back wall to the front wall a hot air circulating heating duct 9, which has its rearend 10 turned downwardly in a substantially vertical position so that the opened end 11 thereof is adjacent the lower edge of the burner compartment 2. The vertically extending portion 10 of the heating duct is located outside of the compartment 2, and forms an inlet for air from,

the outside room.

The. longitudinally disposed portion 9 of the air duct extends through the back wall 4 of the compartment and out through the front wall 3, the front end thereof having a grid 12 mounted therein. The inlet and outlet end of the air duct communicates with the air outside of the burner compartment 2, and is closed so that no communication is provided with said burner compartment. The duct is substantially rectangular in shape, of smaller dimensions than the burner compartment, and is centrally located therein so that the side walls 14 and 15 are spaced the Inent.

away from the walls 7 and 8 respectively of burner compartment, thus providing passageways for the hot air from the burner to pass up around and heat the duct 9. The top and bottom walls 16 and 17 res ectively are spaced away from the top and bottom walls 5 and Grespectively of the burner compartment.

A burner 18 is located in the lower part of 6 the burner compartment 2 for heating the duct 9 and thetop plate 5. Means are pro- Vided for causing the heat from the burner 18 to be conducted to the under side of the front end of the top plate 5 so that heat will travel along the length of said top plate, and

comprise a pair of plates 19 and 20 secured to the top side 16 of said duct 9. These plates form, with the duct, a partition which closes the passages at the sides of duct 9, between the duct and the side walls of the burner compartment, from a point at the rear wall 4, forwardly to a point terminatingadjacent the front wall 3 of the burner compart- The front ends 21 and 22 of plates 19 and 20 respectively are turned up to close the space between the plates and the top plate 5 of the burner compartment, and are so arranged and spaced relative to the top plate as to cause the heat from the burner 18 to pass through a narrow restricted opening formed by the spaced adjacent ends 23 of the bafile plates 21 and 22. A flue 24, which communicates with the burner compartment 2, is provided at the top rear corner of said burner compartment and the bottom 6 of said burner compartment is provided with a series of small apertures 25 for admitting air to mix with the fuel in order to secure complete combustion of said fuel.

Spaced slightlyfrom the side walls 7 and 8 .of the burner compartment are walls 26 and 27 respectively, which form vertically disposed narrow passageways for air which enters at the bottom edge of the burner compartment, as shown in Fig. 5, and after being heated by the side walls 7 and 8 passes out through apertures 28 formed in the top plate 5. l

In the operation ofthis stove, when the fuel is ignited at the burner 18, air passes up through apertures 25 in the bottom plate of the burner compartment and mixes with the fuel. The heat from the products of cornbustion passes up around the side walls of the air duct 9 against the under sides of the .jacent to the front end of the top plate 5,

where the plates terminate. At this point the gases pass upwardly through the open passageways against the under side of top plate 5, thence rearwardly through the restricted opening formed by the bafile plates 21 and 22 along the under side of top plate 5 tothe flue 24, which is located at the extreme rear edge of said plate.

In this manner the heat from the burner heats all sides of the air duct 9 as well as the top cooking plate 5. Heating of the air duct causes the air therein to be discharged through the grid 12 and fresh air to be drawn in through the open end 11 of the duct. The heat from the burner also heats the said walls 7 and 8 of the compartment, thus heating the air in the passageways formed by the walls 26 and 27 to cause the air to be circulated up- Wardly and discharged through the openings 28 of the top plate 5.

Although but one specific embodiment of this invention has been herein shown and described, it will be understood that numerous details of the construction shown may be altered or omitted without departing from the spirit of this invention as defined by the following claims.

I claim:

1. In a stove, a housing forming a compartment, a heating duct extending substantially horizontally through said compartment and having no communication therewith, said duct having an inlet and an outlet each communicating with the air outside of said compartment, the inlet end of said duct being at the back of said compartment and being turned down ina substantially vertical position,the lower end thereof being adjacent the lower edge of said compartment, 2. burner in said compartment for heating said duct, a top plate forming the top side of said compartment, a flue communicating with said compartment adjacent one edge of said top plate, means 101' conducting the heat from said burner to the under side of said top plate at the end opposite to said flue, and means for concentrating the heat at the inter mediate portions of said top plate so as to cause the major portion of said heat to travel along the intermediate portions of said top plate substantially throughout the length thereof.

2. In a store, a housing forming a compartment, a heating duct extending substantially horizontally through said compartment and having no communication therewith, said duct having an inlet and an outlet each conimunicating with the air outside of said compartment, the inlet end of said duct being at the back of said compartment and being turned down in a substantially vertical position, the lower end thereof being adjacent the lower edge of said compartment, :1 burner in said compartmcntfor heating said duct, a top plate forming the top side of said compartment, a flue communicating with said compartment adjacent one edge of said top plate, a horizontally disposed partition in said compartment located below said flue outlet and extending from the back wall and both side walls of said compartment forwardly terminating adjacent to but spaced away from the front wall of said compartment so as to conduct the heat from said burner to the underside of said top plate at the end opposite to said flue so as to cause said heat to travel along the length of said top plate, and diagonally disposed vertical partitions at the forward end of said horizontal partitions for concentrating the heat at the intermediate portions of the top of said duct and top plate.

Signed at Chicago this 26th day of Nov., 1926.
