2 Claims.

My new invention relates to space heating, and, in particular, relates to the accomplishment of such heating by means of the combustion of fuel gas within the atmosphere within the space to be heated.

An object of my new invention is to provide a method by which the atmosphere of an enclosed space may be circulated in comparatively large quantities and be admixed with the gases of combustion resulting from the burning of fuel gas within the atmosphere of the space. Other objects of my new invention will be made apparent in the following specification.

My new invention will be understood from the following specification taken in connection with the accompanying drawing in which:

Figure 1 illustrates the complete heater in front elevation.

Figure 2 illustrates a cross-section taken along the plane 22 of Figure 1.

Referring to the drawing, the main body of the heater consists of a box, the front of which is open, the top, bottom, back and ends of which are made of metal sheets 4, 5, 6 and I respectively. A grate covering the front of the heater is formed by sheet metal strips 8. An opening in the lower rear side of the heater is covered by a grate formed by sheet metal strips 9. A metal sheet H3 is disposed within the heater, contacting the rear side of the heater and sloping upward therefrom. A gas burner I l is disposed within the heater and fuel gas is led thereto through supply pipe l2. A fan l3, which is maintained in position by strap iron supports I4, is mounted in a circular opening through the rear side of the heater above the plate I 0. Fuel gas is burned by burner II in the conventional manner, the air enters the heater through the grate formed by sheets 9 and the lower portion of the grate formed by sheets 8, and flows thence upward by the burner contacting the plate l0 and flows thence through the upper portion of the grate formed by plates 8. The fan I3 causes air to flow from the room through the heater over the plate H) and thence through the uppermost portion of the grate formed by plates 8, the result of which is to admix a comparatively large quantity of the air in the space surrounding the heater with the gases of combustion which flow upward from the burner. This admixture takes place after the gases of combustion which flow from the burner, and the air which is caused by the fan to flow through the heater, have passed from the heater.

While I have described in detail one form of apparatus by which my new invention may be carried out, it should be understood that I do not propose to limit my claims to the details shown. Broadly described my new invention consists in burning gas within the atmosphere of an enclosed space and by means of forced circulation admixing comparatively large quantities of the atmosphere of such space with the gases of combustion resulting from the combustion of'the fuel gas.

I claim:

l. A circulating heater comprising a casing, a heating compartment in the lower portion of said casing, a heating element in said compartment, a blower compartment in the upper portion of said casing, an inlet opening in the rear wall of said blower compartment, a blower adjacent said inlet opening, a discharge opening in the front wall of said casing common to both compartments, and an inclined balfle separating said compartments and terminating with its forward edge adjacent said common discharge opening for deflecting heated gases of combustion towards said discharge opening, whereby atmospheric air from the room being heated is drawn through said inlet opening and delivered to said discharge opening for mixing with said heated gases of combustion.

2. A circulating heater comprising a substanb tially rectangular casing, a heating compartment in the lower portion of said casing, a heating element in said compartment, an air inlet for said heating compartment, a blower compartment in the upper portion of said casing, an inlet opening in the rear wall of said blower compartment, a blower adjacent said inlet opening, an elongated longitudinally extending discharge opening in the front wall of said casing common to both compartments, a longitudinally extending inclined baflle separating said compartments and terminating with its forward edge adjacent said common discharge opening for defleeting heater gases of combustion towards said discharge opening, whereby atmospheric air from the room is circulated through said blower compartment for admixture with the heated gases of combustion at the point of discharge through said common discharge opening.
