ISADOR GREENWALD AND JOSEPH BLAUSTEIN, OF PITTSBURG, AND MORRIS Z. WEISS, OF MCKEESPORT, PENNSYLVANIA.

LAMP-EXTINGUISHER.

Specification of Letters Patent.

Patented Sept. 20, 1910.

To all whom it may concern:

Be it known that we, (1) ISADOR GREEN- WALD, (2) JosnPH BLAUSTEIN, and (3) MORRIS Z. Wnrss, (1) subject of the King of Hungary, 2) and (3) citizens of the United States of America, residing at (1) and (2) Pittsburg, and (3) McKeesport, in

the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Lamp-Extinguishers, of which the following is a specification, reference being had therein to the accompanyin drawing.

This invention relates to lamp extinguishers, and the primary object of our invention is to provide a lamp burner with simple and effective means for snufling or extinguishing the flame of the wick when the lamp is accidentally tilted or upset.

A further object of our invention is to furnish'an oil lamp burner with spring held shutters adapted to be automatically released to extinguish the flame of a lamp, thereby preventing explosions, fires and the destruction of property and lives.

These and such other objects as may hereinafter appear are attained by a mechanical construction that is simple, applicable to various types of oil lamp burners, and highly efficient as a safety device for lamps.

The invention will be hereinafter specifically described and then claimed, and reference will now be had to the drawings forming a part of this specification, wherein there is illustrated a preferred embodiment of the invention, but it is to be understood that the structural elements thereof can be varied or changed as to the size, shape and manner of assemblage without departing from the scope of the invention.

Reference will 'now be had to the drawings wherein Figure 1 is a side elevation of a portion of a lamp provided with the extinguisher,

Fig. 2 is a similar view partly broken away and partly 1n vertical section, Flg. 3 1s a perspective view of the lamp burner partly broken away and partly in section, Fig. 4 is a front elevation of a portion of the extinguisher, showing the same in an open position, and Fig. 5 is a similar view showing a portion of the extinguisher in a closed position.

In the accompanying drawings the reference numeral 1 denotes the body or receptacle portion of a lamp, said body being sup ported upon a suitable pedestal or base 2 and adapted to contain an illuminating oil, as kerosene. The top of the body 1 is provided with a neck 3 and screwed or otherwise mounted in the neck 3 is the lower reduced threaded end 4 of a cylindrical burner casing 5, said casing having the upper end thereof provided with a cap 6.

7 denotes a vertical wick guide carried by the cap 6 and the reduced end 4 of the casing '5, and in this guide is adjustably mounted in the usual manner a wick 8.

9 denotes posts carried by the cap. 6 and connected to said posts is a stepped annular chimney support 10 having a plurality of horizontal annular platforms 11, 12 13 and 14. The platform 11 has diametrically opposed inner-edges thereof connected by a spider 15 through which extends the wick guide 7, and upon this spider adjacent to the rounded sides of'the guide 7 are mounted bearings 16 and 17,. livotally connected to said hearing by pins 18 are the arms 19 of shutters 20, these shutters when closed extending over the upper edge of the wick guide whereby the flame of the wick will be snuffed or extinguished.

21 denotes small gear wheels or racks mounted upon the lower ends of the arms 19 at one side of the extinguisher, these small gear wheels or racks meshing with each other, whereby the shutters can be moved in unison. Mounted upon the spider 15 is a compression spring 22 adapted to bear against one of the shutters and close both of said shutters when released.

denotes a bearing carried by the spider 15 and pivotally connected to said hearing, as at 2 1 is an arm 25 having the upper end thereof bent toward the wick guide 7 and provided with a tooth 26 adapted to engage the inner edge of one of the shutter arms 19 and hold said shutters in an open position. The lower end of the arm 25 extends below the spider 15 and is provided with a curved right angular extension 27 having a reduced end 28. The lower end of the arm is connected by a coiled spring 29 to one of the arms of the s ider 15, said coiled spring normally holding the tooth 26 in engagement with the arm 19 of the shutter.

30 denotes a pin adapted to engage the reduced end 28 of the extension 27,'said pin being carried by the upper end 31 of a bracket 32, the upper end of said bracket being loosely mounted in the reduced end 4 of the casing 5 and in the cap 6 carried by said casing, The bracket 32 is provided with an opening having a weighted rod 33 suspended from the reduced end 4 of the burner casing 5, said rod having the upper end thereof provided with a head 34 held by the reduced end 4 of the burner casing 5, while the lower end thereof is provided with a weight 35. The rod 33 directly above the bracket 32 and adjacent to the head 34 is provided with a conical shaped head 36 adapted to normally engage the bracket 32.

37 denotes a lever pivotally mounted, as at 38 upon the horizontal platform 12 of the support 10, said lever having the upper end thereof provided with a tooth 39 ada t ed to extend into an opening 40 proviolied therefor in the arm 19 of the shutter 20, which opposes the shutter under the action of the spring 22. The lower end of the lever 37 is curved to extend through an opening 41 in the platform 13., said lever extending downwardly under the platform 14 and upwardly to provide a handle 42.

A lamp. extinguisher constructed in accordance with our invention operates in the following manner :-When'the lamp is accidentally tilted or upset, the weight 35 causes the rod 33 to swing by gravity, and as the head 36 of said rod engages the bracket 32, said head will be lowered and the pin 30 thereof will lower the reduced end 38 of the extension 27 swing the upper end of the arm 25 to the right whereby it will release one of the. shutters 20, and the spring 22 engaging the shutter will immediately close said shutters. The rod 33, weight 35 and head 36 constitute gravity actuating means for moving the arm 25, and to restore the shutters to their normal position after the lamp has been placed in an upright position, the lever 37 is moved to swing the.

shutters open whereby the spring pressed arm 25 can again engage one of the arms of the shutters. The lever 37 constitutes means in conjunction with the gear wheels: 21 for restoring the. shutters to: their normal posi tion.

The lamp extinguisher in its entirety is made. of light and durable metal similar to ordinary lamp burners and can be used in connection with any type of burner having a fiat wick.

Having now described our invention what we claim as new, is

1. A lamp extinguisher comprising the combination with a burner casing, a chimney support carried thereby, and a wick guide extending through said casing, of a pair of pivoted shutters adapted to be closed over the end of said Wick guide, gear c0nnections between said shutters for simultaneously opening and closing them when one of the shutters is shifted, means 'connected to one of said Shutters for shifting it whereby both of the shutters will be actuated, a pivoted lock arm adapted to normally engage one of said shutters and maintain the shutters in open position, a vertically movable member engaging said lock arm and adapted when shifted in one direction to move the lock arm clear of the shutter whereby the shutters can be simultaneously actuated, and a gravity movable element extending through said member and provided with means for shifting the member when said element is moved.

2. A lamp extinguisher comprising the combination with a burner casing, a chimney support carried thereby, and a wick guide extending through said casing, of a pair of pivoted shutters adapted to be closed over the end of said wick guide, gear connections between said shutters for simultaneously opening and closing them when one of the shutters is shifted, means connected to one of said shutters for shifting it whereby both of the shutters will be actuated, a pivoted lock arm adapted to nor mally engage one of said shutters and maintain the shutters inopen position, a vertically movable member engaging said lock arm and adapted when shifted in one direction to move the lock arm clear of the shutter whereby the shutters can be simultaneously actuated, a gravity movable element- 3.
