HYDROCARBON-BURN ER.

SPECIFICATION forming part of Letters Patent No. 417,152, dated December 10, 1889.

Application filed July 27, 1889, Serial No. 318,976. (No model.)

To all whom, it may concern:

Be it known that I, JAMEs A. CowLEs, a citizen of the United States, residing at ,(Jhicage, in the State of Illinois, have made certain new and useful Improvements in Hydrocarbon-Burners, of which the following is a specification, reference being had to the accompanying drawings.

Figure 1. is a side elevation of my improvement. Fig. 2 is a plan view. Fig. 3 is an end View. Fig. 4C is an end view of one of the forked brackets used and two air-chambers in position, but removed from the flamespreader. Fig. 5 is a view in vertical section of two air-chambers. Fig. 6 is a side elevation of forked'braeket and lower air-chamher. Fig. 7 is a detail of upper air-chamber and arm. Fig. 8 is a side elevation of burner located in a coolestove.

The object of this invention is to provide a serviceable hydrocarbon-burner, and the nature of its construction is herein shown.

A is a retort-pipe formed and coiled in parallel lines, as shown in Fig. -2, with one end at about the center of the coil bent downward, as indicated in the dotted lines in Fig. 1.

B is the flame-spreader, made of sufficient length and width, and angular in form, as particularly shown in Fig. 3, with the angular surface on the under side, and within this angular-shaped flame-spreader is located the retort-pipc A. From the center of the under side of the flame-spreader descends the tube C, and through this tube passes the vertical part of the retort-tube A. To the lower end of this vertical part of the retort-pipe attached a common. T-conneetion, to which is attached the pipes E E at the right and left. These two pipes and the T constitute and form the burner-pipe. At or near each end of the burner-pipe is a jet-hole F.

G is an angular bracket having the upper end H forked, which forks fit snugly against the outer angular surface of the flame spreader, and are attached thereto by screws or nuts and at the other end support the airchamber 1, which is located immediately over the jet-hole F.

J is a second air-chamber, located above the first one I, and supported by an arm K extending therefrom and attached to bracket G by means of a screw. This arm is angular,

so as to locate the air-chamber directly over the first one. (See Fig. 7.) Belowthe burnerpipe is located the lighter-pan L.

The outer or supply end of retort-pipe A is connected with any continuous supply of oil, which 'oil is governed in its flow into the retort-pipe by valves in the usual way. At first a limited supply of oil is allowed to pass into the retort-pipe, when it soon appears In the lighter-pan L, in which is placed any kind of wickingpreferably asbest-us. A lighted match is applied. In a short time the retortpipe and flame-spreader above are sufficiently heated to readily vaporize the oil as fast as it is fed into the pipe-retort, whence it passes down into the burner-pipe and out through the jet-holes F F, (when it is igniteth) up through the two air-chambers I and J. These two air-chambers serve the purpose of con centrating around and mingling air with the upwardly and rapidly moving flame. This is done in each chamber; hence twice as much air is mingled with the flame by the use of two chambers aswhen but one is used, and hence the more thorough and complete is the combustion. The upper air-chamber has a wlder opening at the base than the lower one has, so.

that it can extend over the first one and leave a space between the two for air to enter the second one. As the fiaine escapes from the upper chamber it impinges against the angular flame-spreader above, and by the angle is divided and passes a part to each side of the spreader. The flame as it impinges against the oblique sides of the flame-spreader gives forth a milder and softer sound or noise than when it impinges against the surface of a flamespreader at right angles with the course of the flame. This form of the flame-spreader renders the noise soft and unobjectionable. This flamc-sp reader also serves as a protector to the retort-pipe against the intense heat arising from the combustion.

The tube C protects the vertical part of the retort-pipe.

This burner can be used in cook or heating stoves, or in ordinary grate-fires. The angular flame-spreader is in the form of a trough with the bottom shaped as shown in Fig. 3.

I clain1 Y In a hydrocarbon-burner, the combination, 5 with a hollow angular flame-spreader, of a retort-pipe located Within the Spreader and terminating in a burner located beneath the I spreader, angular bracket-arms secured to i the spreader, and air-chambers supported by I said bracket, substantially as described.
