IMPROVEMENT IN LAMP-EXTINGUISHERS.

Specification forming part of Letters Patent No. 191,976, dated June 12,1877; application filed March 17, 187 7.

To all whom it may concern Be it known that I," GEORGE D. KILMER, of. Wilmington, in the county of New Castle and State of Delaware, have, invented a new and valuableImprovementinLamp-Extinguishers; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to theletters and figures of reference marked thereon.

Figure 1 of the drawings is a representation of a central vertical section of my lamp-extinguisher; and Figs. 2, 3, and 4 are detail views thereof. Fig. 5 is plan View, with the cap thrown back. Fig. 6 is adetail view, and Fig. 7 is a vertical central sectional view showing lever G in position.

This inven tion relates to devices for automatic'ally extinguishing the flame of lamps; and. it consists in the construction and arrangement hereinafter particularly set forth.

In the accompanying drawings, A designey-supporting springs A wick-tube A wick-feeding device A, and hinged-slotted two jaws, which are curved at the top and hinged together by a bent rod, 1). The jaws B B are provided with perforations a a, (see Figs.3 and 4,) which register, so that'the bent rod b can be readily changed from one The rod 0 is bent, as described, so that it may readily be removed from one set of perforations and inserted in the other set. Jaw B is higher than jaw B. When they are slipped down over wick-tube A the upper end of said wick-tube presses against the inside of the upper part of said shorter jaw 13 A ger of an explosion. (lap A prevents saidjaws'from being separated from the burner.

O designates a small lever, one end of which is enlarged and bifurcated at C so as to embrace the' said wick-tube'A while the other end 01 extends outward through an opening, 0, in the lower part of cap A. The ends of the bifurcated parts of the lever O are bent down at 0 0, so as to raise the enlarged part of the lever G, which supports the wick-tube. By pressing down on thisouter end the cleftend 0 is caused to press against the under edges ofjaws B B, so as to raise them above said wick-tube A and close them together, thereby extinguishing the lamp without inverting it. This lever O is shown in detail in Fig. 6. l.

W'hat I claim as new, and desire to secure by Letters Patent, is I The longer jaw B and shorter jaw 13, provided with perforations a a, in combination with the removable bent rod b, wick-tube A and slotted cap A, substantially as described and for the purpose set forth.

In testimonythat I claim the above I have hereunto subscribed my name in the presence of two witnesses.

GEORGE DUGLAS KILMER.
