GEORGE FREDERICK JAMES AND IVAN E. SMITH, OF NEW YORK, N. Y.
ATTACHMENT FOR STOVES.
Specification of Letters Patent.
Patented Apr. 5 1921.
Application filed. August 14, 1920. Serial No. 403,557.
To all w ham it may concern:
Be it known that we, GEORGE FREDERICK JAMES and IVAN E. SMITH, citizens of Great Britain, and residents of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Attachments for Stoves, of which the following is a specification.
Our invention relates to an attachment for gas and oil stoves, and the invention consists mainly in a spiral and horizontally fluted structure, located in the space above the burner whereby the upward currents of heated air are retarded and deflected as hereinafter set forth.
The invention also consists in the specific construction and combinations as hereinafter described and pointed out in the claim.
In the accompanying drawings to which reference is made and which form a part of this specification:
Figure #1 is a sectional elevation of an oil stove showing, in side elevation, our invention applied thereto and a Fig. # 2 is a sectional plan view taken on the line 2-2 of Fig. #1.
In the drawings 3 designates an oil stove of the usual or any approved construction having a lid 4: which may be removed, and a perforated top 5. Within the stove is held our draft deflecting device 6 which by preference is suspended from the top 5 by a spider 7, bolt 8 and nut 9, but which may be held in place by any other suitable means. The said draft deflector is, by preference, made of a single strip of sheet metal and is annular and spiral in form having a central passage 10, and the inner edge of the spiral has the formation of flutes 12 which are radial and which diminish in depth from the inner to the outer edge of the spiral so that while the metal retards the draft and retains the heat, the upward currents of air are diversified by the flutes. Furthermore by fluting a maximum amount of metal is involved which becomes heated and thus retains and makes available a large amount of heat. The operation of forming the flutes of itself produces the annular and spiral formation so that a single operation upon a straight, narrow, strip of sheet metal results in the complete device.
As here shown the lower volute is soldered at 13, to the body of the stove, it being deflected at that point to make contact with the stove thus staying the device, making the whole structure stable.
Having thus described our invention what we claim as new and desire to secure by Letters Patent is:
The combination with the body of an oil or gas stove of a draft retarding and deflecting device suspended in the combustion chamber the same being in annular volute form the spirals being radially fluted and the flutes diminishing in depth from the inner to the outer edge, substantially 'as shown and described.
