JOHN HARPER, OF FAIRFIELD, IOWA.

LIQUID-FUEL BURNER.

Specification of Letters Patent.

Patented Aug. 27, 1912.

Application filed May 8, 1912. Serial No. 695,898.

adapted for fluid fuels generally and par ticularly crude oil and petroleum.

My invention consists of an oblong double burner comprising a base burner and a superposed over-flow reservoir burner vertically adjustable relative to the base burner whereby vaporization of the fuel may be increased or diminished as required for greater or less heat.

My invention further consists of a the shield to protect the wall of a fire-box not lined by brick.

My invention further consists of the parts and combination of parts as hereinafter described and pointed out in the claims.

In the accompanying drawings forming a part of this specification Figure l is a perspective view of my burner. Fig. 2 is a vertical sectional view of the same. Fig. 3 is a cross sectional view, and Fig. 4c is a detailed sectional view showing the wick in place.

Referring more particularly to the drawings A denotes the baseburner which is of an oblong rectangular shape provided with longitudinal channels a running lengthwise, extending from end to end of the burner where they join, forming an endless trough for the liquid fuel. Midway between said said channels is a groove in which is secured a wick a running longitudinally of the base and coextensive with said channels a. Midway of its length, said wick following said groove, forms a circle around a threaded connection a This connection serves at its lower end as a union for the feed pipe, While its upper end being elongated and threaded serves for union of an adjustable nozzle hereinafter described. a a denote detachable standards at each end of said base. B denotes the reservoir burner superposed above the base burner by said standards a The burner B consists of a cylinder closed at each end, slightly shorter than the base-- burner and of less width, and provided on top with a series of openings 5.

B denotes the burner nozzle screwthreaded its entire length, and passes centrally through the reservoir burner in threaded holes therein, its lower end engaging the threads in the connection a whereby it is adjustable vertically and being rigidly attached to the reservoir burner serves to regulate the vertical adjustment of this burner relative to the base burner. Said nozzle is provided with two openings for supplying the liquid fuehone at its upper end 6 and another opening 6 leading to the hollow interior of the reservoir burner.

C denotes the feed pipe, its upper end connects with the fuel supply tank, not shown, and its lower end is joined to the connection a At this point under the base burner the feed pipe turns at right angles passes through the center of a shield hereinafter described whence it again turns at right angles and is projected vertically above the vertical wall of said shield.

D denotes a shield which passes under the base burner, turns at right angles thereto and projects upwardly at one side thereof, where it is provided with draft openings d. D denotes a slide damper for said openings having its side edges flanged to form ways for slidably mounting said slide on the upright portion or wall of said shield.

In operation the burner can be readily lowered into the fire-box of the stove and rest upon the grate; the upper or reservoir burner is then overflowed, the,liquid fuel escaping through the openings in the top of this burner and running over the sides falls into the base-burner. The fluid also escapes through the upper end of the nozzle and this admits of igniting the burner at this point whence the burning liquid is carried by gravity to and around the upper burner and thence to the base-burner. To adjust the burner for a hot fire the reservoir burner is raised higher above the base-burner thereby giving a greater vertical spread to the flame. This vertical adjustment of the upper burner relative to the lower is effected by turning the nozzle in the required direction to engage the threaded connection a The feed pipe can be passed through an opening drilled in the stove at any suitable point depending upon the size and. structure nished; one pair for supporting the burner at its lowest vertlcal ad ustment, and a higher pair for the maximum adjustment. It is evident however that I may dispense with said standards and depend entirely upon the nozzle support at the center of said burner.

Having thus described my invention, hat I claim and desire to secure by Letters Patent is z 1. An oblong liquid fuel double burner comprising an oblong base-burner, an bb'j long reservoir burner superposed upon and supply fuel to said base burner, a nozzle connect-ing said burners midway of their length r I provided With a fuel escape opening into the reservoir burner and a like opening above said reservoir burner, means for vertically adjusting the reservoir burner relative to the base-burner, and a fuel supply pipe communieating with said nozzle.

2. An oblong liquid fuel double burner comprising an oblong rectangular base-v burner, an oblong reservoir burner superposed upon and held in parallel relation to and adapted to supply fuel to the baseburner, a nozzle connecting said burners provided With a fuel escape opening above and an opening into the reservoir burner and adapted to vertically adjust the reservoir burner relative to the base-burner, means for supplying fuel to the nozzle, a shield having a vertical Wall adjacent to one side of said oblong burner provided with draft openings therein, and means for regulating 1 the draft through said openings. held in parallel relation to and adapted to 1 In testimony whereof affix my signature in presence of two Witnesses. e
