ANDREW T. STILL, OF .KIRKSVILLE MISSOURI.

BURNER.

To all 'whom it may concern.'

Be it known that I, ANDREW 'I`. STILL, ay citizen of the United States, residing at Kirksville, in the county of Adair and State of Missouri, have invented certain new and useful Improvements in Burners, of which the following is a specification.

My invention relates to a burner, and particularly to a type of burner in which means is employed to cause fuel in combustion to move in converging paths which intercept each other, and the primary object of my invention is the provision of devices by the use of which to utilize a greater percentage of the heat units in a fuel substance.

With the above and other objects in view, my invention consists in the discovery disclosed herein and in the mechanism to practice the invention, and in the novel features and in the novel combination and arrangement of parts hereinafter more specifically described, and all particularly pointed out in the claims hereunto appended.

I attain these objects by the mechanism illustrated in the accompanying drawings which are made a part of this specification,

' and in whichv- Figure 1 is an elevation, partly in central vertical section, and partly broken away. Fig. 2 is a section through the mixing head.

A preferred embodiment of my invention is described as follows:

For the purpose of obtaining a greater proportion of the molecular energy from a liquid or gaseous hydrocarbon, I have constructed what is termed a deflecting element 3 comprising a circular tapering portion 4 with the forward end 5 open, and a rear iange 6 to secure the element to the burner. The defiector may be of any suitable or desired contour lines. Preferably it consists of a hollow frustum of a cone open at both ends and disposed in advance of the burner and is adapted to cause burning gases to move in converging paths which intercept each other at a point in advance of the deflector. The furnace member 7 and the dome member 8 of the burner each has an external annular ange 9 through which are inserted bolts 10 to hold the members together and to secure the deflecting element in position. The space 1l between the members is an expansion chamber. The short Specication of Letters Patent.

Application 1ed July 6, 1908.

Patented Apr. 26, 1910. serial No. 441,941.

lengths of pipe 12 serve to maintain the fiange 6 and the ange 9 a predetermined distance apart to provide vfluid passages 13. The annular series of jet apertures 14 afford fluid fuel outlets from the burner. The upright tubular boiler 15 rests upon the foundation 16 which incloses the firebox 17 in which the burner is disposed. The tank 18 holds a liquid hydrocarbon which is adapted to carburet steam which is passed from the boiler through pipe 22 into and through pipe 19 into the tank 18, and through pipe 20 to the spraying or mixing head 21, and thence through pipe 26 to the burner space 11 and through the jet apertures 14.

Air is mixed with the carbureted steam by -the employment of the principle of the Bunsen burner through the air pipes 30. The force with which the carbureted vapor passes out of the lower end of the pipe 26 creates a partial vacuum in the tube 27 and causes an inrushing of air through the pipes 30.

In operating when the Huid fuel under pressure arrives at the apex of the furnace member it will then be in the presence of intense heat and will be expanded and will pass through the burner with force. Immediately upon its exit through the jet apertures combustion will take place and the direction of the lines of energy will be changed by the angle of the adjacent surface of the deiieeting element and the lines of energy will cross at a point in advance of the deiecting element. The passage 13 will permit a circulation therethrough.

It will readily appear that my invention has a wide range of application, and is not limited to any one class of burners, but may be applied to any burner with which it is desired to increase the heat from a given amount of fuel by causing the flame or lines of combustion to move in converging paths which intercept each other.

Having` thus fully described my invention, what I claim as new, and desire to secure by Letters-Patent, is,

1. In a burner, a deflecting element comprising a hollow frust-uin of a cone open at both ends and disposed in advance of the burner and adapted to cause burning gases to move in converging paths which intercept each other at a point in advance of the deflectng element.

2. The combination with a burner and means to supply fuel under pressure thereto, of a deeetor comprising a hollow frustum of a cone open at both ends and dsposed n advance of the burner and adapted to cause burning gases to move in converging paths which intercept each other in advance of the defleetor. 10

In testimony whereof, I aflx my signature in the presence of two witnesses.
