LAMP-'EXTINGUisHEa SPECIFICATION forming part of LettersPatent No. 257,838, dated May 16, 1882.

` Application nieu Aprnaisse. (No model.)

To all whom it may concern:

. lowing is a specification.

Myinvention relates to automatic lamp-extinguishers, by which I provide for and avert the danger existing in the overturning ot' fluidlamps while in use and the'consequeut igniting ot' the fluid itself.

Figure 1 is a side elevation of a lamp with luy device attached andrin position. Fig. 2 isa top view of automatic extinguisher detached from lamp. Fig. 3 is a front View ot' same. Fig. 4is a detailed view of part of the extinguisher.

Similar lettersrefer to similar parts throughout.

A is a narrow band of metal or large wire, shaped to clasp and rigidly adhere to the base of a lamp-burner, Y, and drawing to a narrow neck where it leaves the lamp, and again expanding in a circle of a suitable size to receive and hold the small metallic weight a', which iits looselyT into the circle thus formed.

B is a metallic sleeve, open or closed, but rigidly adherent to the wick-tube, and armed with the spring Z, impinging upon the hinged cap or extinguisher b', forcing the same upon the top of the wick-tube and burning wick and extinguishingthe same. The extinguisher b' is held back from the ilame by tension of the wire C, which is looped to the extinguisher b, and which terminates in a loop, c, slipped over the tongueD and drawn against the shoulder of the tongue D atits intersection with the crossbar d', which cross-bar is soldered to the sides ot the wire A at its narrow part. The tongue D revolves upon the cross-bar d', and operates freely within the circle A, exterior to the lampburner,at right angles to its plane. The weight a', when in position, operates by gravity to hold the tongue D below the periphery ofthe circle A, exterior to the lamp-burner; but when the lamp is overturned tbe weight a is dislodged and falls by gravity, and the pressure of the spring Z is left free to act upon the extinguisher b, and the tongue D is rotated toward thelamp, allowing the looped end c of the wireC to slip freely along the tongue D to its hooked end d, and the lamp is thus' extinguished. Similar results follow when the weight a' is purposely removed, and the iiame may be thus extinguished at any time when desired in ordinary I am aware that the use of a weight operating by the power ot'gravity in various methods to extinguish a fluid-lamp when the same is upset is old and familiar, and I do not claim anything on account thereof.

I am likewise aware of the Patent No. 157,503, and ot' the workings thereof andthe claim made therein, and I do not claim any element or feature of that patent or invention.

What I claim as new, and desire to secure by Letters Patent, is-

1. In an automatic lamp-extinguisher, the combination of the metallic sleeve B, the extinguisher b', the spring Z, the wire C, the tongue D, andthe weight ct', constructed and arranged as herein described and shown.
