BLUE-FLAME GAS 0R OIL BURNER.

Specification of Letters Patent.
Patented July 2, 191%.
Application filed January 9, 1918. Serial No. 211,050.
To all whom it may concern:
Be it known that'l, GEORGE L. BLANCH- ARD, a citizen of the United States, residing at Pomona, in the county of .Los Angeles and State of California, have invented new and useful limprovements' in Elue-lllame Gas or Oil Burners, of which the following is a specification.
My object is to make an improved blue flame gas or oil burner and my invention consists in the novel features herein shown, described and claimed.
Figure 1 is a perspective of a burner head embodying the principles of my invention, parts being broken away to show the construction.
Fig. 2 is a vertical central sectional detail of the burner head and feed pipe.
The deep cylindrical cup 1 is vertically mounted upon a vertical feed pipe 2, and has vertical slots 3 extending from its upper edge.
The cup 1 is an unmachined casting of iron. The cylindrical portion 4 of the cup 1 is straight and in vertical cross-section the metal wall is evenly tapered, being thinnest at the upper edge and thickest at the lower edge. The bottom portion 5 is flat and of an even thickness as great or greater than the thickness of the lower edge of the cylindrical portion 4.
The vertical nozzle 6 extends upwardly from the center of the bottom 5, the main portion 7 being straight and concentric to the cylinder 4, and the upper portion 8 being rounded. The vertical bore 9 is drilled straight up from the lower face of the bottom 5 at the axial center of the nozzle 6 and the jet orifice 10 discharges from the bore 9 upwardly. The metal of the wall around the bore 9 is as thick or thicker than the bottom 5.
The vertical feed pipe 2 is of considerable length and is tapped into the lower end of ,the bore 9.
It is important that the walls of the burner head thus produced are even and homogeneous and harmonious and it is preferable that they be unmachined as far as possible, and that they constantly grow thicker from the upper edge downwardly toward the noz j zle, instead of thinner.
tion. The flow of fuel may be regulated by the size of the orifice 10 and a stop-cock or regulating valve may be used in the feed pipe.
The tendency of air to feed a flame will cause a vacuum in the cup and the outside air will rush in through the slots 3 to mix with the gas which, under pressure, is forced through the small orifice 10, and produce combustion. There is no necessity for an initial partial mixing of the air with the gas as where a mixing tube is used in a Bunsen burner, or a chamber for the mixing of unburned gases. 7
Various changes may be made in the details of construction without departing from the spirit of my invention as set up in the following claims.
I claim:
1. A burner comprising a raw casting forming an imperforate cup having a 1 straight vertical cylindrical wall with vertical slots extending from its upper end and a fiat bottom and a nozzle extending upwardly from the center of the bottom and having a vertical bore and a vertical orifice;
and a vertical feed pipe tapped into the.
lower end of the bore.
2. A burner comprising a raw casting forming an imperforate cup having a straight vertical cylindrical wall with vertical slots extending from its upper end and a flat bottom and a nozzle extending upwardly from the center of the bottom and having a vertical-bore and a vertical orifice;
and a vertical feed pipe tapped 'into the lower end of the bore; said casting being of an uneven thichiess tapering from the nozzle to the upper end of the cup.
In testimony whereof I have signed my name to. this specification.
eno. L. BLANCHARD.
