PATENT OFFICE DESIGN FOR A FLUID FUEL BURNER of Ohio Application January 27, 1936, Serial No. 60,842
Term of patent 7 years To all whom it may concern:
Be it known that we, Birchard L. Matthews and John T. Marvin, citizens of the United States, residing at Lakewood and Fairview Village, respectively, in the county of Cuyahoga and. State of Ohio, have invented a new, original, and ornamental Design for Fluid Fuel Burners of which the following is a specification, reference being had to the accompanying drawing, forming part thereof.
Fig. 1 is a perspective top view of a fluid fuel burner, showing our new design.
Fig 2 is a plan view of the same.
Fig. 3 is a bottom plan view, and Fig. 4 is a cross section taken on line 4-4 of Fig. 2.
The characteristic features of our design reside in a burner device having an annular top portion which at its outer periphery is constituted by a substantial horizontal flat top surface to the inner edge of which is joined a vertically downwardly extending wall of substantial depth. Joined with the lower edge of this vertical wall is an inverted conical surface of substantial width which terminates at its inner portion in a well defined central hole in the burner. At the junction of the inverted conical wall and the vertical portion are a plurality of small boss-like projections whose extremities blend into these two surfaces.
The ornamental design for a fluid fuel burner,
as shown and described.
