Specification of Letters Patent.

Patented June 2, 1908 Application-filedMay 2d, 1906. Serial No. 818,568.

To all'whom it may concern:

Be it known that I, HENRY H. AsHLooK, a citizen of the United States, residing at San Diego, in the county of San Diego and State of California, have invented a new and use ful Hydrocarbon-Burner, of which the following is a specification.

This invention relates -to hydrocarbon burners adapted to be used in connection with the fire boxes of cooking and heating stoves, furnaces, and the like, for the consum tion of li uid hydrocarbon, either in the orm of crude or distilled oil; the invention having for its objects to' avoid carboni zation and consequent stoppage of the oil ducts of the burner.

Further objects of the invention are to simplify and improve the construction and operation of the device.

With these and other ends in view, which will readily appear as the nature of the invention is better understood, the same consists in an im roved construction whereby the li uid fuel 1s discharged into an intensely heate air current to be thereby vaporized prior to its discharge in the form of gas u on the combustion surface; the invention urther consists in the improved construction,

arrangement and combination of parts, to be hereinafter fully described and particu larly pointed out in the claims.

In the accompanying drawings has been illustrated a simple and preferred form of the invention; it eing, however, understood that .no limitation is necessarily made to the precise structural details therein exhibited,

ut that-changes, alterations and modifications within the scope of the invention may be resorted to, when. desired.

In the drawings :F-igure 1 is a sectional perspective view illustrating the invention apphed in position for o eration to the fire box of a cooking stove o ordina construction. Fig. 2 is a top plan view a stove lid supporting the device. Fig. 3 is a sectional detail view showing the invention ap lied to a heatin stove. Fig. 4 is a sectiona detail view, en arged, taken through the supporting lid of-the device, on the plane indlcated by the line 44 in Fig. 2. Corresponding parts in the several figures are indicatedthroughout by similar characters of reference:

A stove lid 1, which may be fitted to .the

65 fire box ofa cooking stove C, as in Fig. 1, or

air s'u ply; v beneatrthe stove lid or cover any desired of 'a heating stove H, as in Fig. 3, is provided with tapped aperture 2 into which screws a pipe 5. The upper end of the ipe is open to permit air to enter and is pre? with a damper or valve ,3 for control ing the The. pipe 5 may be extended distance according to the character of stove or fire-box in connection with which it is to be used, and said i e is rovided intermediateits ends, and e ow t e lid 1, with coils or convolutions 8 whereby a large area of said pipe will be exposed to the heat of the flames 1n the furnace or fire-box. The pipe includes an elbow 9 from which the lower ,terminal ortion of the pipe extends verticall ,ass own.

' he elbow 9' has an aperture 10 disposed above and in alinement with the vertical mixin tube or terminalpipe portion, which latter isspecially designated 5; through the aperture 10 extends an oil feed pi e 11 which is provided with a re lating Va ve 12 and which is oonnectedwit a source of oil supply, such as a tank 13, shown in Fig. 1. The feed pipe mayextend through an ap' erture 14 in the stove lid 1, lugs 4 being employed that extend above the height of the pipe to receive a cooking vessel, as shown in Figs. 1, 2 and 4 of the drawings;

erably fliish i with the top of the lid so as to be e uipped or it may enter through an aperture, as 15,

in the. side of the stove casing, as shown in Fig. 3; said feed pipe being in either case secured, as by means of nuts 16, or in any other convenient manner.

The ate 17 of the fire-box in connection with .w ich the device is used, supports a shallow bowl or-pan 1-8 which constitutes the generator-pan; and in said pan there-is supported a combustion plate 19 having apertures 20. v

A convenient aperture is provided for the insertion-of a torchwhereby the oil in the Igenerator pan may be ignited, said aperture eing formed either in the stove lid, as shown at 21 in Figs. 1, 2 and 4, or in the side of the stove casing, as shown at 22 in Fig. 3; in either case, a valve or damper 23 is provided whereby said aperture may be obstructed when not in use.

In the operation of this device, a quantity of oil is permitted toflow by the valve 12 into the generator pan where it is ignited by the application of a torch through the aperture 21 or 22, as the case may be. The airpipe 5, 5 will thus become heated, so that when oil is permitted to flow slowly through the feed pipe 10 into the terminal 5 of the air pipe, it will become vaporized, forming by admixture with the heated air in the air'pipe, a highly inflammable mixture which is ignited as it issues from the air pipe and is deflected upon the combustion plate Where it will burn with a flame of great intensity. It is to be noted that all ordinary air inlets for supplying air to the fire-box are to be obstructed, so that the air necessary to support combustion will be compelled to enter through the air pipe 5 5", which latter, bein intensely heated, will cause the oil discharge thereinto to become practically instantaneously vaporized.

This invention, by making such changes as will readily suggest themselves to those skilled in the art, may be readily adapted for use in connection with cooking and heat' ing stoves of various patterns, as well as with fire-b bxes and furnaces ofv all descriptions.

of a vertically extending mixing tube below the lid and having an outlet at its lower end, an air conducting 'coil connecting said tube with the lid and opening through the lid, a pan disposed below the mixing tube and constituting a burner, said pan extending under the coil, an oil conducting pi e extending directly from the lid into the in et end of the mixing tube, and means for regulating the passage of air through the coil and to the mixing tube.

In testimony that I claim the foregoing as 'my own, I have ,hereto aifixed my signature in the presence of two witnesses.

HENRY H. ASHLOOK.
