HYDROCARBON-LAM P.

SPECIFICATION forming part of Letters Patent N 0. 700,47 5, dated May 20, 1902.

' Application filed February 7, 1899. Serial No. 704,793. (110 model.) I

To LUZ whom, in may concern:

Be it known that I, THOMAS H. BLAIR, a citi-' zen of the United States, residing at North-- hero, in the county of Worcester andState of Massachusetts, have invented a new and useful Hydrocarbon-Lamp, of which the following is a specification.

The aim of this invention is to, provide a newand improved h ydrocarbon-lam p in which the parts shall be simply and conveniently arranged, in which thesupply of oil orliquid shall be automatically regulated, and in which the oil and vapor can be quickly shut off and controlled when it is desired to extinguish the lamp.

To these ends myinvention consists of the combinations and devices described in this specification and illustrated in the accom-., panying four sheets of drawings, in which-f Figure 1 is a side View, partially broken away, showing the conneetionof two-lamps constructed according to myinvention with an oil-tank. Fig. 2 is asectional view of my pre-.

ferred form of lamp. Fig. 3 is a plan view 1 of the perforated burner-plate. Fig. 4 is a sectional view at right angles to Fig. lot the vaporizing-chamber. Fig. 5 is a plan View of the vaporizing-chamber. Fig. 6 is azview similar to Fig. 1, illustrating amodified form of construction; and Fig. 7 is an enlarged detail view showing the positive shut-01f valve in its closed position. I i

My improved lamp consists of a vaporizingchamber located above a suitable burner, in which chamber is placed a diaphragm'which connects to a valve controlling the supply, so that the pressure generated in the vap'orizing-chamber will automatically regulate the; oil-supply. A' double-valve system is also provided in connection with suitable operat? ing means, so that when the lamp isextinguished the supply of vapor from the vaporizing-chamber to the burner. will be cutoff and simultaneously the supply of oil to the vaporizing-chamber will be positively stopped. f

- The invention also consists of certain improved details of construction hereinafter rewill first describe the preferred form of lamp illustrated in the first two sheets of the drawings.

. 1O designates avaporizing-chamber, which I have shown made circular in form. In the top of this chamber is arranged a ledge 11,

and screwed into the top of the chamber is a perforated cap 12.

Arranged between the ledge 11 and the cap 12, is an asbestos packing and a diaphragm 13.

14:- designates a supply-pipe, and the same may have a suitable valve 15. The supplypipe 14 is screwed into a suitable boss extending from the vaporizing-chamber. Extending from this boss is a feed-pipe'lG, which is bent around, as shown in Fig. 4, so as to be flexible. The end of thefeed-pipeisfitted into the side of a small hollow cup orcylin der 17 which has a valve-seat arranged on the top thereof. This cylinder 17is connected by suitable straps 18 to the diaphragm 13,

so that the same will move up and down with the said diaphragm.

19 designates a square yoke which sur-' rounds the cylinder 17. .The under side of said yoke forms a valve and has a cushion20, .made out of asbestos or other suitable materia'h'arranged to engagethe valve-seat formed 'onthe top of the supply-cylinder 17. -2lis preferably arranged to project from said valve20'down through the valve-seat'formed ronltop of the cylinder 17, so as to prevent by movement of the diaphragm or operating- ;handle any impurities clogging said valve. IQnthe lower side of said yoke 19 is arranged another asbestos cushion, which forms a valve A pin 22. Said valve 22 is set to cooperate with the upper end of a tube 23, which extends up into said chamber 10 to form a valve-seat and a trap to retain theoil in the chamber. This "is an advantageous construction in that a certain amount of oil will be trapped or held on the bottom of the chamber up to the top of .the tube 23, so that a large surface of the same will be exposed to the heat of the lamp.

Extending from the yoke 19 down through the tube 23 is a rod 24, the lower end of which is threaded into an operating-handle 25. This operating -handle 25 is fitted into-tlielower end of the tube 23. The lower end ot the tube loo - handle 25, as shown.

23 is fitted into a hub 27,. The handle and tube are kept in place by means of one or hub and said tube and which fit into an annular groove cut in the shank of the screw- By this means as the screw-handle is turned the rod 2t can be raised or lowered.

The tube 23 has small outlet-holes 28, which permit the vapor to pass out into a suitable chamber for mixing the vapor and air, my construction having a base 29, which is secured to the hub27 by pins or braces 30. The upper end of the base is provided with a perforated plate 81, and the shoulder of the base 29 is provided with a suitable ring of wiclting orabsorbent material 300, which may be filled with alcohol and lighted when it is desired to start the lamp into operation. A suitable mantle S2 is arranged between the bottom of the vaporizing-chamber and the plate 31. I

A collar 33 may be held on the base 29 by suitable clips 34:, and this collar may support a chimney 3G and a porcelain cup 35. A shade 37 may also be arranged to protect the upper part of the lamp and can be secured to the vaporizing chamber by means of suit-able screws 38.

The operation is as follows: The lamp is started into operation by saturating the wicking 2500 with alcohol and lightingthe same. At the same time the screw-handle is operated to raise the valves 20 and 22 from their seats. Oil will then pass up over the valveseat formed on top of the cylinder 17 and will drop onto the bottom of the vaporizing-chamber 10 and will there be converted into vapor, which will fill the chamber, and the excess passing under pressure down through the tube 23 will be forced out through the holes 28 up into the base 29. As the same rushes up into the burner outside the tube 23 air will be drawn into the bottom of the base and mixed with the Vapor, which mingled vapor and air will be ignited by the alcohol-flame and will burn above the plate 31. This will continue the heating and generating of vapor until the supply of alcohol will have burned out, when the lamp will continue in operation. This will render the mantle incandescent and will give a brilliant light. When pressure is increased beyond a desirable point in the vaporizing-chamber 10, the diaphragm will be pushed upward. This will raise the cylinder 17 against the valve 20, and this action will automatically regulate the supply of oil to the vaporizing-chamber by shutting off the supply of oil when the desired pressure is obtained and by opening to allow oil to enter the vaporizing-chamber when the pressure falls or by keeping the valve in such position that the supply will be set to just feed the proper amount of oil to keep the pressure substantially constant. When it'is desired to extinguish the lamp, the screw-handle 25 is seats. This action will simultaneously stop the 1 supply of oil to the vaporizing-chamber and the supply of vapor to the burner.

The arrangement of cylinder 17 and flexible feedpipe 16 isa very desirable one,bccause by this construction the oil is brought to a high temperature before it is allowed to escape into the vaporizing-chamber, and the cylinder 17 thus forms a small reservoir ol heated oil, which is ready for use the instant the diaphragm descends and allows the escape of the same between the valve-seat and the valve 20; t

In Fig. 5 I have shown a modification. In this modification the supply-pipe 16 is brought down under the vaporizing-chamber 10 and is carried up into a valve-chamber40, formed on the inside of the vaporiziug-chamber. Fitting loosely in the valve-chamber 40 and hearing on a seat formed therein is a small Valve 41, which is arranged onthe end of a link 42, which link is connected to the rod 2t and is pivoted at its center to a bracket43.

The upper end of the rod 24.- in this construction is connected to the diaphragm. The lower end of the rod in this construction rests upon but is not connected with a taper plug 44., formed on the shank of the screw-handle 25. The screw-handle in this modification is threaded into the lower end of the tube 23, and the shank of the screw-handle is formed with the taper plug at, which cooperates with a correspondinglytapered seat through which the holes 28 are bored, so that when the tapered plug 44 is screwed up it will out off .the supply of oil to the openings 28. In this construction pressure generated in the vaporizing-chamber will by pressure on the diaphragm operate the valve 41 to automatically regulate the supply of oil. NVhen it is desired to extinguish the lamp, the screwhandle 25 is turned. This will push up on the rod 24 and will force the valve 41 to its seat, thus closing the supply of oil. At the same time the plug 4st will come to its seat and will thus close the opening 28 and will thus stop the supplyofvapor to the burnerand extinguish the lamp. Thus a double valve is formed by this construction-one valve, which automatically regulates the supply of oil and which may be positively closed, and a second valve, which maybe simultaneously positively closed with the first valve to stop the supply of vapor to the burner.

The details herein described may be varied from by skilled and artistic mechanics to form a table-lamp or one to be suspended from the ceiling without departing from the scope of my invention as expressedin the claims. In modifying the construction for asuspensionlamp the feed-pipe 16 can be carried up around through the cap 12, to which cap a supply-pipe extending from the ceiling can be screwed. The construction shown, however, is preferred, as with the same the cap 12 can be unscrewed toget'at the workingparts in the chamber Without interfering with the su pply pipe=or lamp.

, In some casesanextra'number of vapor pipes can be carried'from the'vaporizing" chamber to othermu'rners, and thus form a.

chandelier. Y
