IMPROVEMENT IN LAMP-EXTINGUISHERS.

Specification forming part of Letters Patent N o. 170,064,

dated November 16, 1875; application filed March 16, 1875.

To all whom it may concern.-

Be it known that I, WILLIAM C. GROSS, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain Ilnpiovements in Lamp-Extinguishers; and I hereby declare the following to be a full, clear, and exact description thereof, reference being had tothe accompanying drawings making part of this specification, in {which-v Figure l is a perspective o 'the extinguisher as attached to a wicktube. Fig. 2 is a vertical cross-section with thewick raised. Fig. 3 is` a vertical cross-section with the Wick down.

rEhe object of my invention is to provide a cheap lamp-extinguisher that will not foul or allow dirt to enter the wick-tube; `and it consists in two plates which are pivoted at the top and out of line with the wick-tube, and are operated by springs, as hereinafter set forth.

In the said drawings, A is the wick-tube of a lamp-burner. On the outer surfaces of the"t upper edges of the tube I pivot, by rivets c a, two plates, B B, shaped substantially as sh`own, and having flaring ilangesb b, under which bearsprings c c, having their ends soldered to the base of the burner. Each ofthe plates B O has one of its sides turned at right angles above the pivots, so that they form at their tops a rectangular holding-surface for the wick. The plates together form a hood, which at its baise is larger than the wick-tube.

When the wicl:V is forced up it represses the springs ari'd forces the plates apart, as seen in Fig. 2. The opening between the end of the lamp-wick tube and the bases of the plates allows the air to circulate around the tip of the tube and almost to the burning-point of the wick, thus keeping the wick-tube or oil from heating. y

` When the Wick is drawn down the plates assume the position seen in Fig. 3, and the opening at the base of the plates so enlargesv as to freely allow any dirt or charred Wick which may have accumulated around the top of the plates tofescape, and none Vwhatever goes into the wick-tube to clog the gearwheels.

lThe lsprings c c are soldered in such a way as to protect them as far as possible from any heat from the llame.

The scraping action or effect of the upper edges of the plates B B upon the tip of the wick is'such as to keep it cleared of'charred or gummy matter. r

Having thus describedmy invention, what I claim as new, and desire to secure by Letters Patent, is

The plates B B, arran ed to have openings between their basesan the wick-tube, in combination with the sprin gs c c and wicktube A, substantially as described.
