SPECIFICATION forming part of Letters Patent No. 600,485, dated March 8, 1898.

Application flied January 21, 1897.

To cir/ZZ whmn t 'ntf/.y concern.:

Be it known that I, CORTLAND BALL, of Indianapolis, county of Marion, and State of Indiana, have invented a certain new and useful Oil-Burner; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which like numerals refer to like parts.

My invention consists in improving the construction of oil or gas burners or retort-vaporizers to enable the effectual, safe, and economical use of petroleum, either crude or refined, or gas for cooking or heating stoves or for any other purpose to which the device may be applicable.

A feature of my invention consists in a slid ing cut-olf valve mounted on the pipe that extends horizontally beneath the mixing-chamber, whereby the entrance to said mixingchamber may be closed while the fire is being started. At that time, unless the entrance to the mixing-chamber be closed, the oil7 being under pressure and not vaporized, will be forced up into the mixing-chamber, where it would burn, and the soot and smoke would lill the outlets from such chamber.

In the drawings, Figure 1 is a perspective of my burner. Fig. 2 is a side elevation of the same. Fig. 3 is a central vertical section of the same.

In detail, I provide the burner-supply pipe 6. A valve 7 is used to shut off the flow of oil therein. An air-pipe 12 extends from a suitable tank filled with air under pressure to the burner-supply pipe 6. In it a valve 13 is placed. The construction of the burner is as follows: An oil-pan 14 is preferably cast integral with the retort-supports 15. The bottom of the pan slopes downward from its center to a trough 1G around its periphery, as seen in Figs. 2 and 3. This pan is provided with sand or other material to hold the oil and heat. The supports are preferably three in number and are formed at their upper ends with an outward seat to receive the retort 17, which consists of one or more coils of the pipe 6. In the device shown said pipe is coiled twice about the burner, with its end 18 turn ed down and extending in horizontally immediately above the oil-pan 14. Its end is closed ,trance into the chamber.

Serial No. 620,153. (No model.)

by a cap 19, and at a point above the center of the oil-pan an outlet-opening 20 is formed in the upper side of the pipe. The retort or coil of pipe 17 is held in place by hooks 21, 55 that are held down to lugs 22 on the oil-pan by means of the bolts Vith this construction it is seen that the retort or coil of vpipe is directly over the trough 16 in the'oil-pan, from which the blaze from the burning oil ascends, 6o whereby the oil in the retort or coil 17 is heated and vaporized. The vapor passes upward with considerable force through the outletopening 20 into the mixing-chamber.

The mixing-chamber comprises a lower portion 24, which rests upon the upper inner portion of the supports 15 and has a downwardlyextending annular collar 25 at its middle portion, which registers with a similar upwardlyextending collar 26, forming a passage-way 7o into the chamber above for the vapor issuing from the pipe 18 and the air that is drawn upward with it in its passage into the chamber. The other part of the chamber consists of an oval top orlid 27, with its periphery downwardly extending and provided with a series of openings 28, through which the mixed air and vapor passes downward to the llame. On the under side of such top portion 27, at the center, I provide a deflector29, that curves 8o downward in close proximity with the en- By this means the vapor and air entering are distributed in various directions to contribute to their admixture. A finger-piece 30 is provided on the 85 top of said lid portion 27. The periphery or edge of the base-plate 24 is curved upward, as shown, and the coils .of the retort are placed in the position in relation to the mixing-chamber that is shown, so that the flame 9o of the burner will contact with and be delected against the upper coil of the retort, whereby permanent vaporization of the oil is maintained. The lid or top 27 is held from lateral movement by the lugs 35.

The top portion 27 of the mixing-chamber rests merely upon the part 24 below and therefore can be readily lifted off. The part 24 merely rests upon the supports 15 and can be readily lifted from its place. The retort 10o or coils 17 rest upon the supports 15 and can be readily lifted out of place after releasing the hooks holding them down on their seats. Therefore whenever a portion is Worn out it can be replaced Without trouble or expense. If the retort is burned out, the coils can be replaced by others without buying a new burner.

kIn order to prevent the oil from being forced into the mixing-chamber while the fire is being started, I provide the following shut-off valve: A thirnble 31 envelops and slides upon the pipe 18.v At its lower end it is Constructed fiat, so as to rest upon the pan 14. Upon its two upper arms I secure a fiat'disk 32. The height of the valve is equal, substantially, to the distance from the central portion of the pan 14 to the collar 25, forming the opening into the mixing-chamber. The thimble 31 envelops the pipe 18 so loosely that it can slide thereon. Therefore by means of the handle 33 I can Withdraw it from beneath the opening in the mixer-chamber or, by forcing it beneath such opening, close the same.

What I claim as my invention, and desire to secure by Letters Patent, is-

The combination in an oil-burner having an oil-pan, a mixing-chamber above the same, and a pipe from the retort extending horizontally between the oil-pan and mixingohannber, of a valve consisting of a thirnble slidably mounted on said pipe and a disk on such thlnble to close the entrance into the mixin g-ehamber, and a hand le connected with said valve for sliding the same on such pipe.

In Witness whereof I have hereunto set my hand this 7th day of January, 1897.

CORTLAND BALL.
