oil and the like; and the object of my inven-` tion is to provide a device whereby in the event of a lamp being upset a stream of Water will be sprayed into the flame of the wick to extinguish it before the'oil in the lamp can run out and become ignited.

I attain my object by means of the device herein described andby applying it to a lamp in the manner illustrated in the accompanying drawings, in which- Figure l represents a vertical section through a lamp in which a flat Wick is used with my extinguisher applied thereto Fig. 2, a horizontal cross-section ofthe same on the line :l: m; Fig. 3, a sectional view of alamp havmg a cylindrical wick and a central air-supply tube, showing the manner of lapplying my extin uisher device thereto; and Fig. 4;, a horizontal section on the line y y in Fig. 3.

Like letters of reference designate` like v parts in the several views. n VReferring irst to Fig. 1, A represents the reservoir of the lam and B'the screw-threaded collar into whic the burner C is usually screwed. In applying my extinguisher device to this type of lamp I remove the burner and insert in the collar B a disk D, provided With an outturned flange at the top. Upon the burner I attach a screw-threaded bushing E in order that the burner may be drawn down upon theflan e of the disk D without rotating the burner b The upper end of this vial is constricted andl closed byva ball-valve N of material which will not be attacked by acid contained in the vial.. Frornthe top ofthe receptacle Ga tube J extends through holes rovided therefor in the diaphragme Oat t e bottom and y means of the swiveled v nut F. The disk D is cut out to permit ofl top of the burner to a point adjacent the top oi' the burner and below the burner-cap K.

The receptacle G will be partially filled With water or other hre-extinguishing liquid, and thevial will be filled with sulfuric acid or any other liquid which when mixed with the liquid in receptacle G will generate a gas- E Jrressure su'Hicient 'to force the liquid out om the receptacle through the tube J Should the lamp be upset or turned upon its side sufliciently to permit the oil to run out through the burner, the contents of the vial will at the same time flow into thereceptacle G and upon admixture with the li uid there-v in drive the liquid out through t e tube J, causing it to strike upon the cap K and spray into the flame of the lamp, vthereby extinguishing the flame before the oil from the reservoir can reach it. The valve N seals the mouth of the vial against the ingress of air or liquid, but opens' freely when the lamp is tilted over to permit the escape of the contents ofthe vial. Y

By arranging the extinguisher device as aboveV described it may be sold separately and applied to lamps of this character in general use, or the device may be applied in other ways to'specially-constructed lamp-burners.

To -apply my extinguisher device to central-draft lamps, such as illustrated in Fig. 3,

vceptaclefirmly in place therein. The cap H of the receptacle is provided with the tube J at the top of which is a spray-nozzle S, the receptacle G being so positioned in the drafttube that the .nozzle will stand within the perforated zone of the cap R. Should this the nozzle S will be sprayed through the perforations in the cap R in all directions and will extinguish the flame at thetop 'of the wick P.

While I have described my extinguisher as vapplied to lamps, I wish it understood that I intend to include within said term also lamps such as are used in oil-stoves and the like and which have reservoirs supplied with either the flat wick or the central-draft burner, as above described.

amp become upset, the liquid driven thro ugh ICO Without limitingl myself to the speciic construction of the device or manner of applying it as described herein, what I claim IIO as my invention, and desire to secure by Letters Patent, is-

1. In combination with a lamp, an extinguisher comprising a receptacle containing separate compartments communicating with one another at the upper end and containing iire-extinguishing and gas-producing liquids respectively, and means for conveying liquid from the receptacle to the ilame in the burner when the two liquids become mixed by the overturning of the lamp.l

2. In combination with a lamp, an extin- V guisher comprising a liquid-reoeptacle, an

open-ended vial to contain a gas-producing liquid inserted within said receptacle, a duct leading from the receptacle to the burner, and means for delivering the liquid from said duct to the iiame in the burner should the lamp be overturned.

3. A lamp-extinguisher comprising a liquid-receptacle, means for attaching said receptacle to a lamp below the burner, a duct leading from the receptacle to a point adjacent the top of the wick, a vial containing a gas-producing liquid inserted in the receptacle, and means for delivering the liquid Jfrom said vial t-o the liquid in the receptacle should the lamp be overturned.

4. A lamp-'extinguisher comprising a receptacle having two intercommunicating compartments containing a liquid and a gasproducing substance respectively, a tube projecting from the top of said receptacle, and means for attaching the receptacle within the reservoir below the burner with the tube in position to deliver the contents of the rece tacle into the f lame in the burner should the amp be overturned.

5. The combination, with the reservoir of a lamp having a central draft-tube therein, of a receptacle having two intercommunicating compartments containing a liquid and a gas-producing substance respectively, a tube projecting from the top of said receptacle, and means for securing the receptacle within the draft-tube with the tube from the receptacle in position to deliver the contents thereof into the ame of the burner should the lamp be overturned.

In testimony whereof I have allixed my signature in presence of two witnesses.

JOHN E. RICHARDSON.
