SPECIFICATION forming part of Letters Patent No. 776,161, dated November 29, 190er.

Application led February 9, 1904. Serial No. 192|80Z. (No model.)

To L7/Z whom, 'llt' may concern.'

Be it known that I, W'ILLTAM THoMAs VVooD, a citizen oi" the United States, residing at Nashville, in the county of Davidson and State ot rlennessee, have invented a new and useful Hydrocarbon-Burner, of which the following is a specilication.

The invention relates to improvements in hydrocarbon-burners.

The object oi the present invention is to improve the construction of hydrocarbon-burners and to provide a simple and comparatively inexpensive one designed for incandescent lighting from kerosene-oil and capable of effeetuall y eliminating sweating, dripping, condensation, and all foul odors usually resulting from burners ot' this class using kerosene.

A further object of the invention is to provide a burner of this character in which the parts will be compactly arranged and which by reason o1 such compactness will enable the vaporizer and the other parts of the burner to be sufficiently heated without the employment ot' supplemental burners or subiiames.

Another object of the invention is to provide a hydrocarbon-burner in which the carbon deposit will be reduced to a minimum and which will enable the parts to be readily and quickly cleaned when necessary.

With these and other objects in View the invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended, it being understood that various changes in the form, proportion, size, and minor details ci construction within the scope of the claims may be resorted to without departing' from the spirit or sacrificing any of the advantages of the invention.

In the drawings, Figure l is a perspective view ot' a hydrocarbon-burner constructed in accordance with this invention, the mantle being omitted in order to illustrate the other parts oi' the burner more clearly. Fig. 2 is a vertical sectional view of the same. Fig. 3 is avertical sectional view taken substantially on the line 3 3 of Fig. 2. Fig. 4; is a horizontal sectional view taken substantially on the line 4. 4f of Fig. 2. Fig. 5 is a detail sectional view illustrating the construction ol" the removable tip of'the nozzle.

Like numerals of reference designate corresponding' parts in all the iigures oi the drawings.

l designates a substantially semicircular burner-body of tubular form provided at its ends with upwardly-extending burner-tubes 2, having' gauze burner-caps 3, which may be of any desired construction and which are litted on the vertical burner-tubes in the usual manner. The tubular burner-b j dy may be constructed of any suitable material, and it is provided between its ends with an upwardlyextending mixing or commingling chamber consisting ot a tube 4 and a gauze or perforated cap iitted on and extending' above the tube 1i. The mixing or commingling chamber is located intermediate ot' the burner'- tubes and oft from the line -iiiassing through the centers oi such tubes. The pertorations or apertures are adapted to admit air to the mixing or commingling chamber, and an enlarged opening' 6 is provided at the top of the mixing-chamber for the passage of vapor. The vapor is discharged into the mixing or commingling chamber in a ine spray from a nozzle 7 of a vaporizer 8. The nozzle, which is threaded into the vaporizer, is lin'ovided with an outer wrench-receiving portion and is readily removed to enable it to be quickly cleaned when necessary.

The nozzle is provided with a removable tip 31, iitted above the lower end oi the nozzle and provided with a tapering groove 32, located at the side adjacent to the center or inner portion of the burner and forming a very line discharge-opening for adaptil'lg the burner for the use oi' kerosene or coal oil as a fuel. The tip consists of the upper end ol a substantially vertical rod 233, located at the Vouter side of the mixingor conimingling chamber and bent inward at its upper portion to form an 'arm 34, which extends between the tip of the cap and the lower end of the nozzle. The lower portion oi' the rod is bent to form an inclined loop 35, which is substantially U-shaped, as shown, and the lower side of the loop is extended and bifurcated at its upper end 36 for engaging a groove 37 of a removable plug 9. The loop serves as a handle and also operates as a spring, whereby the rod is securely retained in position. The rod is adapted to be readily detached for enabling the groove 32 of the tip to be readily cleaned. By this construction the burner is prevented from becoming clogged or inoperative by any carbon deposit. Also the mixing or commingling chamber is located substantially between and in close proximity to the burners,whereby intensely-heated air is supplied to the said mixing-chamber. Also the burner-body is intensely heated, and the distance between the mixing or commingling chamber and the burners is reduced to a minimum, and the passages from the mixing-chamber to the burner-tubes are highly heated, thereby effectually preventing sweating, dripping, and condensation and at the same time eliminating the foul odors which usually result from the use of kerosene in burners of this character. In order to further facilitate the cleaning of the discharge-nozzle, the burner-body is provided at a point directly below the mixing-chamber with the removable plug' 9, fitted in a threaded opening' of the burner-body and normally closing the same and threaded, as shown. By removing the plug 9 an instrument may be readily passed through the mixing' or cornmingling chamber into the nozzle to remove any carbon deposit without detaching the said nozzle.

The vaporizer is approximately rectangular, and it consists of upper and lower transverse tubes 10 and 11 and vertical tubes 12 and 13, the tube 12 being shorter than the tube 13 and carrying the said nozzle 7. The upper end of the tube 12 communicates with the adjacent end of the upper transverse tube 10, and the inner end of the lower transverse tube 11 is closed, as clearly illustrated in Fig. 2 of the drawings. The vertical tube 13, which constitutes a feed or supply tube, communicates with the upper and lower tubes 10 and 11, and its lower end 14 is threaded to receive a union or other suitable means for connecting' it with the source of supply. The source of supply may be a font or reservoir of any desired character, and the kerosene-oil is designed to be ejected from such font or reservoir by means of air under pressure, whereby a continuous supply of kerosene oil or vapor will be supplied to the burner. Also any form of valve may be employed for controlling' the flow of fuel to the burner, and such valve may be located at any desired point to suit the character of the lamp in which the burner may be used, the burner being adapted for portable and stationary lamps and similar lighting devices; The vapor or oil passes upward through the supply-tube into the vaporizer or gas-generator 8 and is converted into gas and is ejected at the short discharge-tube 12 into the mixing or commingling chamber, as before explained. The tubes of the vaporizer or generator form ducts or passages, and they are highly heated by the burner, being located between the mantles and above the burner-tubes, as shown, thereby obviating the necessity of employing subflames or supplemental burners for such purpose. The lower transverse tube 11 forms a trap, and in the event of the overiiow of oil the lower transverse tube 11 will become illed before the oil rises higher in the vaporizer. Any oil flowing into the .lower transverse tube or trap 11 will become vaporized and will pass upward through the feed-tube 13 to the upper transverse tube 10.

The body of the burner is provided at its ends with upwardly extending converging arms 15, which are adapted to support the vaporizer and which are located off from the line passing through the centers of the burnertubes. r1 he vaporizer is provided at opposite sides of the feed-tube 13 with projecting lugs 16, which are secured to the arms by screws 17 or other suitable fastening devices. By this construction the vaporizer and the parts carried by the same may be instantly detached from the rest of the burner when necessary or desirable for cleaning or otherwise.

The vaporizer is provided with an upwardlyextending rod 18, forming a support for the sleeve 19, which is provided with projecting mantle-supporting hooks 20. The sleeve and the hooks form an adjustable mantle-support, which is secured at any desired adjustment by means of a set-screw 21, piercing the sleeve and engaging the rod 13. The rod 18 extends upwardly from the center of the upper transverse tube 10, and the supporting-rod 22 depends from the center of the lower tube 11 and carries at its lower end a cup or receptacle 23, adapted to receive the alcohol for heating the parts of the burner in starting the same. The parts are arranged above and in close proximity to the cup or receptacle 23, whereby they are highly heated by the same and condensation and deposits of hydrocarbon are prevented when lighting the burner. rlhe vaporizer is also pierced at the upper portion of the supply-tube in line with the upper and lower tubes 1() and 11 and is provided at those points with threaded iianges for the reception of screws 24 and 25, which afford access to the upper and lower -horizontal passages of the vaporizer for cleaning the same. As the passages of the vaporizer are straight, they may be conveniently cleaned and access may be had to any portion of the vaporizer.

The burner is mounted upon a bracket or yoke 26, having upwardly extending arms and secured to the bottom of the body of the burner by screws 27 or other suitable fastening devices, the arms of the burner being iso- IOO IlO

lated or protected from the burner by asbestos 26 or other suitable material to prevent them :from being heated by the burner. The bracket or yoke 26 is provided with a depending' threaded stem 29, which may be mounted on a lamp fixture, stand, font, or receptacle or other support. A globe support or holderl() of the ordinary coniig'uration may be arranged on the threaded stem 29 immediately beneath the arms of the bracket 26, as shown.

It will be seen that the hydrocarbon-bui'ner is especially adapted for burning' keroseneoil, that its parts are compactly arranged `to permit the burner to occupy a comparatively small space and also to enable the parts of the burner to be etfectually heated by thel contents of the cup when starting the burner. and also to be maintained at a high temperature by the heat of the burner after the same is started, whereby subiiames and supplemental heatingl means are eliminated. Also it will be clear that owing to the close proximity of the vaporizer, the mixing-chamber, and the body of the burner to the burnertubes sweating', dripping, condensation, and foul odors are elfectually prevented, and that carbon deposits are reduced to a minimum. Also it will be apparentthat the vaporizer may be instantly detached and the parts ot' the burner may be readily and quickly cleaned should the same become necessary or desirable. The semicircular body portion of the burner forms a recess at its inner or concaved side to provide a central open space above the alcohol or starting cup, so that the llame therefrom is afforded an open space or passageway for heating' the vaporizer. The burnerbody is also heated by the llame simultaneously with the vaporizer in order to prevent the lirst vapor which enters the body Yfrom condensing; rapidly and producingl a slow, inactive, Weak, smoky flame, that would not maintain the vaporizer at the proper temperature for producing' the required amount ol vapor to properly start oli' the lig'ht. rlhe vaporizer has straight passages which are easily cleaned, and it provided with a trap for catching' any overflow oi the oil to prevent the latter from rising in the vaporizer and interfering' with the production oi' steady white light free from Hare or pulsation. lt has been found by experience that where the Vapor lifts the fiuid and causes an overi'low in that part ot' the vaporizer next to the mixing-tube the llame is rendereiil yellow and is caused to pulsate. This objection is overcome by the use ot' the trap.
