IMPROVEMENT IN LAMP-EXTINGUISHERS.

Specification forming part of Letters Patent No. 164,334,'dated June 8, 1875; application filed April 14, 1875.

To all whom it may concern:

Be it known that I, JOHN O. SODERSTROM, of the city and county of Pepin and State of Visconsin, have invented a new and Improved Lamp-Extinguisher; and I do hereby declare that the following is a full, clear, and exact description of the same, referencebeing had to the accompanying drawing forming a part of this specification, in which- Figure 1 is a plan view; Fig. 2, a side elevation; Fig. 3, a sectional elevation.

The invention relates to alamp-extinguisher, whose construction and distinguishingfeatures will first be fully described, and then pointed out in the claims.

A represents a burner, and B a wick-tube. In the bell-shaped wick-tube cover 0 I arrange two opposite and oppositely concaved plates or jaws, D D, each resting against a rear spring, d, of any preferable form, one working within the other. Between and against these jaws work up and down the outwardly-bent arms 6 c of a lever, E, said arms passing through holes 6, while the main stem is bent and pressed by a spring, F, at the point 6 The lever end is then bent upward and provided with a weight, H, sufliciently heavy to hold the plates or jaws D D apart after they have been once opened, but not heavy enough to counteract and overcome the tension of spring F when the jaws are closed.

The coal on the end of wick ordinarily militates very materially against the efficiency of ordinary extinguishers, but is of no consequence with mine; while mine is not alone thoroughly efficient in performing its function of-extinguisher, but also is held at either of its two adjustments without difficulty or chance of mutation.

Having thus described my invention, what I claim as new is- 1. The-opposite concave jaws D D, sliding one within the other over the burning wick, as and for the purpose specified.

2. The combination, with sliding jaws, of diverging arms 6 6, arranged to vibrate on the inside of and unattached to said jaws, as and for the purpose set forth.

3. The combination, with lever E, having arms 6 e, of end weight H and spring F, arranged to hold the jaws back from the wicktube, or allow them to be slid over it by the spring.
