Application filed July 28, 1916. Serial No. 111,859.

To'aZZ whom it may concern Be it known that I, ALEKSANDER PLUnowsin, a subject of the Gzar'of Russia, residing at Waterbury, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Lamp-Extinguishers, of which the following is a specification.

This invention relates to certain new and useful improvemnts in lamp extinguishers.

. The primary obj ectof the invention is the provision of a pneumatic device adapted for extinguishing the light in an ordinary lamp without the necessity of bringing the hand of the operator near the chimney of the lamp.

A further object of the invention is the provision of a ready extinguisher for lamps formed as a part thereof when the lamp is manufactured, the same being readily operable whenever desired for use.

A still further object is to provide a compressed air tank in connection with a lamp whereby an air blast controllable for extinguishing the lamp is operatively arranged.

.Yth these general objects in view and others thatwill appear as the nature of the invention is better understood, the same consists in the novel construction, combination and arrangementof parts hereinafter, more fully described, illustrated in the accompanying drawings,- and then claimed.

In the drawings forming a part of- '35 application and in which characters refer to corresponding parts throughout the several views :Figure 1 is a side elevation of a lamp provided with the present device partially shown in vertical section. Fig. 2 is a transverse sectional view taken upon line 11-11 of Fig. 1. Fig. 3 is a front view ofthe air blast nozzle, and, Fig. A is a transverse sectional view thereof. The present invention broadly consisting .in the provision of an extinguisher for lamps, the same is herein illustrated in connection with a kerosene lamp of. substantially the usual construction having an oil reservoir 11 with a burner 12 mounted there- '50 on, the latter being provided with a glass chimney .13 while a base it .is provided for supporting the reservoir 11 by means of a pedestal 15.

. It will be understood that the reservoir this Specification of Letters Iat'ent.

v the valve openings Patented J an. 2, 1917.

supporting pedestal and base may be integrally formed of glass or metal as found desirable, an axial bore 16 being herein provided in the pedestal communicating with the chamber 17 in the base 14. A communieating pipe 18 extends through the reservoir 11 from the bore 16 to a point in the top of the reservoir 11 adjacent the burner 12, a threaded bushing 19 being provided in the upper end of the said pipe.-

A tubular casing 20 is fitted within the bore 16 having a closure cap21 threaded upon its lower free end within the base chamber 17. Acentral partition 22 is arrangedin'the casing 20 having a flap valve 23 upon its inner face adapted for normally closing a valve opening 24 centrally arranged in the said partition.

Anair compressing piston 25 is tightly fitted for reciprocating in the lower portion of the casing'20 having an operating rod 26 attached thereto, the said rod extending axially of the said casing being slidably arranged through a stuffing box 27 centrally carried by the-casing cap 21. An air inlet port 28 is provided in the cap 21, it being understood that the piston 25 is valved in the usual manner sothat the vertical reciprocations thereof by means of the rod 26 the inlet 28 into the casing 20 and thence through the partition valve opening 24: into the upper portion of the casing 20. A handle 29 is arranged upon the outerend of'the piston 26 while the latter has a hinge joint 30 allowing the piston rod to be angularly bent and the free portion thereof to be engaged over a hook "31 in the'base chamberlT, as illustrated by dotted lines in Fig. 1 of the drawing.

Spaced plates are arranged adjacent the upper end of the casing 20 having alining valve openings 33 therein while a slide port 35 extending therethrough normally maintained out of alinement with 33 by means of a-spring 36. The valve 34 is provlded with a stem 37 projecting outwardly of the pedestal 15 arrangedv with a finger piece 38 thereon whereby the valve may be forced inwardly against the actionof the spring 36 for bringing the port 35 thereof into alinement with openings 38, thereby allowing the compressed air within'the casing 20 to pass into .valve 3 1 closely fits between the said plates havlng a the small chamber portion 39 in the upper end of the said casing so that the air may freely pass through the pipe 18. A fanshaped nozzle 40 is screw-threaded by means of a nipple 41 into the bushing 19, a plurality of outlet perforations 42 being arranged in the face of the said nozzle adjacent the burner 12 in an inclined position beneath the horizontal air inlet plate 43 of the burner.

1n the operation of the device it will be understood that a piston 25 will be actuated from time to time for the purpose of maintaining a supply of air under compression within the casing 20 between the partition 22 and the plates When designed to extinguish the light of the burner 12, the flame of which is herein illustrated at 44, the finger piece 38 will be depressed thereby sliding the valve 34 to its open operative position, allowing the compressed air to flow through the pipe 18 and the nozzle 40. The air will thus be forced through the perforations 42 of the nozzle and will pass through the air receiving plate 43 of the burner, providing a draft for extinguishing the blaze 44 by blowing out the same. A device is thus provided upon a lamp which is ready for immediate use in extinguish ing the light and is readily operable by the hand when grasping the lamp supporting pedestal l5 and without the necessity of bringing any part of the body near the lamp chimney 13, it being intended to prevent the accidental burning of the operator during the extinguishing of the lamp.
