STOVE.

Specification of Letters Patent.

Patented June 8, 1920.

Application filed December 7, 1918. Serial No. 265,791.

To all whom it may concern:

Be it known that I, PHILIP P. MELANSON, a subject of the King of England, residing at Moncton, in the Province of New Brunswick and Dominion of Canada, have invented a new and useful Stove, of which the following is a specification.

The stove upon which this application is based, includes novel means whereby cold air may be drawn in from below and heated, novel means being provided whereby the products of combustion may traverse the stove and escape, the construction being such that the air will be heated to a high degree, with a very small expenditure of iuel.

It is within the province of the disclosure, further, to improve generally and to enhance the utility of devices of that sort to which the present invention appertains.

WVithin the scope of what is claimed, I do not bind myself to the specific form shown in the drawings, since, within the field of his skill, a mechanic may work; changes without departing from the spirit of the invention.

In the drawings :*Figure 1 is a vertical section showing a stove embodying the invention. Fig. 2 is a side elevation wherein parts appear in section; Fig. 3 is a top plan; Fig. 4 is a cross section on the line H of Fig. 1.

In carrying out the invention there is provided a base 1 supported on legs 2, or otherwise. The bottom of the base 1 has a depending nipple 3 connected to a pipe 4 controlled by a damper 5. There are openings 6 in the bottom of the base 1, and the side wall of the base may be supplied with openings 7 controlled by dampers 8 which may be pivoted at 9 to the side wall of the base. The base 1 includes a top 10.

A central or main flue 11 is carried by the top 10 and communicates with the base 1. Side or auxiliary flues 12 are connected with the top 10 and communicate with the base 1. The numeral 14: denotes an outer drum, and the numeral 15 marks an inner drum, the bottoms and the side walls of the drums being spaced to form a chamber 17 closed at its top by a flange 16 on the inner drum 15, the flange extending across the upper edge of the outer drum 14. The outer drum 14 is provided with a collar 18 carrying one end of a pipe 20. The auxiliary fiues 12 pass through the bottom of the outer drum l4: and are assembled with the bottom of the inner drum 15, the flues thus communicating with the base 1 and with the interior of the inner drum 15. The upper end of the main flue 11 is assembled with the bottom of the outer drum 14, and the fine 11, therefore, communicates with the base 1 and the chamber 17 which exists between the drums l4 and 15. The heating means may be of any sort, but, if desired, it may be in the form of a burner 21 located in the main flue l1 and carried by a pipe 22 extended laterally through the flue 11. The openings 6 in the bottom of the base 1 are located directly below the auxiliary flues 12.

In practical operation, the products of combustion proceeding from the burner 21 pass upwardly through the flue 11, into the chamber 17, and out through the pipe 20, the inner drum 15 being heated in this way, and the outer drum 14 being heated also, the drum 14 serving to heat the air in the room, about the said drum. When the products of combustion move upwardly through the flue 11, cold air is drawn into the base 1, through the openings 6, through the pipe 4 if the damper 5 is open, or through the openings 7 if the dampers 8 are open. In this way, a regulated supply of air is provided, the pipe 4 forming a means whereby air may be drawn from a point outside of the building, if desired. The air passes upwardly through the fiues 12 into the drum 15 and there is heated, the heated air passing out of the top of the drum. The construction of the device is such that a maximum amount of air may be heated with the expenditure of a minimum amount of fuel.

I claim A stove comprising a base including a top, a bottom and a side wall; inner and outer drums having their bottoms and their side walls spaced to define a chamber having an outlet for the products of combustion; a central main flue connected to the top of the base and to the bottom of the outer drum and establishing communication between the interior of the base and the chamber; auxiliary flues disposed about the main flue, the auxiliary flues passing through the bottom of the outer drum and being connected to the bottom of the inner drum and to the top of the base, the auxiliary fiues establishing communication between the base and the interior of the inner drum, the bot- 5 tom of the base having openings alined with the auxiliary flues, the bottom of the base having an aperture alined with the main flue, and there being an aperture in the side wall of the base; and dampers controlling the respective apertures. 10

In testimony that I claim the foregoing as my own, I have hereunto afiixed my signature.

PHILIP P. MELANSON.
