HYDRoCAREioN-BURNER.

SPECIFICATION forming part of Letters Patent No. 753,825, dated March 1, 1904.

Application filed August 31,1903.

To aZZ whom) it may concern:

Be it known that I, Lnoros E.' COLEMAN, a citizen of the United States, residing atSanta Ana, in the county of Orange and State of California, have invented a new and useful Hydrocarbon-Burner, of which the following is a specication.

This invention relates to-hydrocarbon-burners of that class which are employed for heating purposes and which are specially adapted to b e disposed for operation in the fire-boxes of ordinary cooking or heating stoves.

. My invention has for its object to provide a device of this class which shall be simple in construction and inexpensive 4and which may at the same time be easily manipulated, which shall not be liable to accumulate soot or dirt, and in which the accumulation of carbon within the retort of the device shall be rendered inocuous by the peculiar construction of the device, whereby such accumulations may be removed and disposed of fromtime to time. i

With these and other ends in View my invention consists in the improved construction, arrangement, and combination of parts, which will be hereinafter fully described, and particularly pointedy out in the claims.

In the accompanying drawings, Figure 1 is a vertical sectional view of my improved hy- `drocarbon-burner, showing the same applied in operative position in the fire-chamber of an ordinary cook-stove. Fig. 2 is a sectional detail view taken onthe line 2 2 in Fig. 1.

. Corresponding parts in the several figures are ndbited by similar numerals of refer- @IlQ/e,

1 designates the retort upon my improyed burners, which is of inverted-frustum shape, the sides of said retort being upwardly diverged and said retort' being provided with a closely-fitting cover 2, which may be integral therewith. The lowerend of the retort has a closure consisting of a bushing 3, comprising a screw-threaded portion 4 and a head 5, projecting beyondl said screw-threaded porti0n,'so as to form afiange 6. The lower end of the retort is reinforced, asV shown at 7, and interiorly screw-threaded to be engaged by the screw-threaded portion 4 of the bushing.

Serial No. 171,449. (No model.)

' Awasher 8 may beinterp'os'ed between the 'flange 6 and the reinforced portion 7 to form a tight joint.-

The bushing 3 has a central screw-threaded perforation through which extends the feedpipe 9, the lower end of which is connected by an L 10 with a pipe 11, leading to the source of supply. Thepipe 9 may be extended any desired distance into the retort, said distance being easily regulated, owing to the fact that the said pipe 9 is exteriorly screw-threaded throughout its entire length, thus enabling any desired adjustment to'be easily effected.

The top 2 of the retort has an opening 12, in which is tted an lL 13, with which the vapor-pipe 14 is suitably connected. Said vaporpipe 14 is connected by an L 15 with the vertically-disposed burner-pipe 16, the upper end of which is tightly closed by a cap 17, whileI the side of said burner-pipe is provided with a minute opening 18. This opening faces a spray-plate 19, the lower edge of which'has a notch 20, whereby it is adjusted, straddling the vapor-pipe 14 and leaning against the L 13, as will be clearly seen in Fig. 1. In this manner the said spray-plate may be supported with suflicient security and yet in such a manner as to enable it to be easily detached when 'l it shall be desired to disassemble the parts.

21 designates a bed-plate, which is provided with a surrounding fiange 22, which takes the place of the grate usually employed in a stove. In other words, in order to apply my invention the grate is removed from the stove and the bed-plate21, which is made 'of a size and shape to correspond with the grate, is mounted in place thereof upon the supports usually provided for such grate. It follows from this that the bred-plate used in connection'with my invention may be made of any desired size and shape, provided, of course, that it is provided with the ange 22 and also with a depression23, whereby it is, likewise characterized. This vdepression is forthe reception of any possible overflow, which is likewise confined by the flangev 22. The bed-plate is provided with an opening 24, which is of such an area that the retort '1 when seated therein, as shown in Fig. 1, shall project for the greater part of its height below' said bed-plate. This IOO is an important feature of my invention, inasmuch as I thereby avoid any possibility of overheating the lower part of the retort and the rapid formation of carbon resulting from such overheating. As will be seen, however,-

the lower part of the retort is of ample size to accommodate any impurities that may accumulate therein for a long time, and it will further be seen that by removing the bushing at the bottom of the retort any such impure accumulations may be readily removed. Let it here be noted that the bushing is not exposed to the heat of the iiame evolved by the burner and that consequently there is little or no chance of its becoming fastened in such a manner, as to render its removal difcult.

25 in the drawings designates a portion of an ordinary stove in the fire-box of which my improved burner is disposed for operation. From the foregoing description, taken in connection with the drawings hereto annexed, the operation and advantages of my invention will be readily understood. In order to apply my improved hydrocarbon-burner to al stove, it is only necessary to remove the grate from such stove and substitute in place thereof the bed-plate 21, which, as above stated,`has

placed in position in the bed-plate, the pipe' 1l leading' to the source of oil-supply is connected up, and the device is now in condition for operation. It is obvious that a valve, as 26, is to be provided upon the oil-pipe in order that the supply of oil maybe regulated. In order to start the llire, the supply-valve is slightly opened, thus permitting the oil to overiiow the feed-pipe within the retort, the latter being meanwhile heated by means of a torch or other suitable means until the oil is vaporized, when it will ascend through the passages 12, 13, 14, 15, and 16, escaping through the port 18, from which it is projected against the spray-plate 19, the .spray thus projected being easily ignited, said spray being commingled with air supplied through the ordinary draft-opening in the stove, which said draft-opening is disposed above the bed-plate 21. The intensity of the i'iame may be regulated by means of the valve 26, and the fire may be extinguished by closing the valve.

I have in the foregoing described a simple and preferred construction of my improved hydrocarbon-burner, and I desire it to be nnderstood that I do not limit myself to the precise structural details herein set forth, but reserve the right to any changes, alterations, and modifications which may be resorted to within the scope of my invention and without departing from the spirit or sacrificing the utility of the same. Thus it may be mentioned that, if desired, -a plurality of retorts and burners may be mounted in a single bedplate; but this has not been specifically shown., for the reason that it would amount simply to a duplication of the burner which forms the subject of this present invention.

Having thus described my` invention, I claim- 1. In a device of the class described,the combination of a bed-plate having an opening, an inverted-frustum-shaped retort seated in said opening and projecting' for the greater part of its height below said bed-plate, a bushing forming a closure for the lower end of the retort, a feed-pipe adjustably connected with said bushing, and connecting means between said feed-pipe and the source of supply.

2. In adevice of the class described, a bedplate having an orifice, an inverted-frustumshaped retort seated in said orifice and projecting for the greater portion of its height below the bed-plate, a bushing forming a closure for the lower end of the retort,a feedpipe connected adjustably with said bushing and extending upwardly into the retort, connecting means between the lower end of the said feed-pipe and the source of supply, a permanent closure for the upper end of the retort, a vertically-disposed burner-pipe having an opening in the side thereof, connecting means between said burner-pipe and the retort, and a spray-plate disposed in front of and adapted to receive the discharge from the opening in the burner-pipe.

3. In a device of the class described, the combination of a retort, a vapor-pipe extending from the latter, a vertically-disposed burnerpipe connected with said vapor-pipe and having an opening in the side thereof, and asprayplate disposed in front of said opening and having a notch in its lower edge engaging the vapor-pipe.

4. In adevice of the class described, a retort having a permanent closure at its upper end, an L connected with said closure, a vapor-pipe connected with the L, a vertically-disposed burner-pipe connected with said vapor-pipe and having an opening in the side thereof, and a spray-plate notched in its lower edge to straddle the vapor-pipe and contacting' with the L connected with the top of the retort, being.thereby supported upon said retort in a position to receive the discharge from the oritice in the burner-pipe.

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