LAMP-EXTINGUISH EB.

Application filed.Apri1 10, 1917.

To all whom it may concern:

Be it known that 1, JOHN MUnonK, .a-citizen of the United States, residing at Hazleton, in the county of Luzerne and State of Pennsylvania, 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 improvements in lamp extinguishers.

The primary obj ect of the invention is the provision of an extinguisher or snuffer for lamps such as kerosene or coal oil lamps, the same being automatically operable for extinguishing the light upon turning down the wick of the lamp.

A further object of the invention is the provision of an extinguisher in the form of an attachment for burners of that variety employing an oil contacting wick, the light being readily extinguished upon turning down the wick and rendered ready for light-- ing upon again elevating the wick, provision being made for the free .movement of the wick through the burner without interruption by the extinguishing device.

While it is understood that lamp extinguishers have been heretofore provided for operative shifting transversely of the .path of movement of a burner wick, such is not now broadly claimed but the .gist of my invention resides in an extinguisher of this general type adapted for ready arrangement in its inoperative gposition permitting free movement of the wick ,uneffected by the extinguisher duringsuch times, for instance, as the initial insertion of the wick within the burner.

\Vith these general objects in view and others that will appear as the nature of the invention is better understood, the same consists in the novel construction, combination and arrangement .of parts hereinafter fully described illustrated in the accompanying drawing and pointed out in the appended claim.

In the drawing forming a part of this application and in which like numerals refer to corresponding parts throughout the several views.

Fig. 3 is .a top plan view of the structure shown in Fig. 1 with the guard cap removed.

Fi g. at is a detail vertical central sectional view through the burner with the extinguisher in its released arrangement.

Fig. 5 is .a perspective view of the usual wick tube altered for the convenient mounting of the extinguisher thereon.

Fig. 6 is a erspective view of the extinguisher detac ed, and,

Fig. 7 is a plan view of the anetal blank from which the extinguisher is preferably formed.

The present embodiment :of my invention is herein illustrated in connection with the well known form of burner 10 employed with wick lamps and comprising a chimney mounting circular base 11 having chimney retaining springs 12 and provided with a centrally arranged wick tube 13 for accommodating a wick 1% slidably therein and longitudinally operable by means of a turn shaft 15 having a plurality of toothed wheels 16 which engage the said wick through side slots 17 in the said tube. The tube 13 has an overlapped crimped longitudinal jointure ror seam 18 while a protecting cap 19 is hinged as at 20 to the base 11.

A number ofattaching an extinguisher to a burner .of the above described well known structure consists in forming the extinguisher or snuffer 21 preferably from av single piece of sheet metal and hinging the same to .a modified portion of the seam '18 of the wick tube 1-3 as at22. I The attaching means herein illustrated consists in forming parallel lugs 23 from the side portions of the seam 18 at an interrupted point 24: therein, the .said lugs having suitable journaliirg perforations 25 and .it being understood that the interruption of the seam 18 provides an open slot permitting free .access to the interior of the tube 13 and to the wick 14 positioned therein.

The snufier metal blank 26 having the cross-member 27 bent into angle-iron ar rangement providing a flange28 perpendicularly projecting from the top of the blank 26. The upright portion 29 of the blank 26 has the opposite halves bent in- 21 is formed of a substan-' .tially T-shaped wardly into engagement with each other forming an attaching leg 30 provided With a foot 31 arranged with a perforation 32 therethrough adapted for the reception of a pivoting pin 33 for hinging the saidfoot 31 between the lugs 23 with the pin 33 arranged through the perforations 25 of the latter.

The foot 81 has a serrated'toe portion 34 in the form of teeth which project through the interrupted seam portion 24: into engagement with the wick 14- when the snufler is vertically or obliquely arranged as best illustrated in Fig. 1 of the drawing while the pivoted end of the snufter has a curved face 35 forming the bottom. of the foot 81 which lies within the interruption or slot 24 of the tube when the snuffer 21 is substantially horizontally positioned, thereby permitting free longitudinal movement of the wick 14 as best illustrated in Fig. 4:.

From this detail description of the invention it will be understood that the extinguisher 21 may be pivotally mounted upon the tube 13 in any manner permitting a portion thereof such as the foot 31 to be free from interference with the wick 14 when in one position but arranging another portion of the extinguisher such as the teeth 34 so as to normally engage the wick 14 whereby the extinguisher is automatically projected over the upper open end of the tube 13 and withdrawn therefrom upon the shiftin of the wick 14 downwardly and upwarc ly respectively through the operation of the usual wick operating turnshaft 15. W hen it is desired to insert or withdraw the wick 1 1 from the tube 13 the cap 19 is opened and the extinguisher 21 moved down wardly to a substantially horizontal position upon the base 11 as illustrated in Fi 4 of the drawing as well as by dotted lines in Fig. 2 thereof, it being noted that in the latter view the cap 19 has been closed which may retain the eXtinguisher 21 inactive by reason of the inwardly flaring portion 36 of the cap 19.

V'Vhen the wick 14 is properly arranged within the tube 13, the extinguisher 21 is swung to its vertical position with the flange 28 overlying the upper end of the tube 13 andthe wick let will be in ing the flange 28 from the tube and wick and exposing the latter for purposes of lighting as illustrated in Figs. 1 and 3 while a reverse turning of the shaft 15 in the direction indicated by the arrows in Fig. l, lowers the wick 14 and returns the snufter 21 to its vertical position with the flange 28 thereo' overlying the tube and the wick and thereb extinguishing the latter 2 of the drawing as well as by dotted lines in Fig. 1 thereof. lVhen the snufl'er 21 is normally arranged for operative movement in the manner described after the wick has been initial y inserted in snufi'er 21 is prevented from assuming its inactive horizontal position by reason of the fact that any continued upward move ment of the wick 14 tending to depress the snuffer would bring the latter into contact with the central portion 36 of the cap 19, this engagement insures the operative positioning of the suffer at all times when the cap 19 is closed after the snufler has been once positioned release of the snufler 21 from the wick whenever required by opening the cap 19 and pivotally moving the snufier 21 to its horizontal position.

The base 11 may be provided with a slot 37 adjacent the tube 13 and beneath the lugs 23 if desired for accommodation of the swinging movement of the snuffer 21 while the opposite ends of the flange 28 of the snufi'er may be inclined as at 38.

A serviceable extinguisher for lamps is insert or withdraw a wick such as during the renewing thereof.
