1, JOHN PROSSER of The Cedars, Portland Avenue, Upper Clapton, Middlesex,
do hereby declare the nature of this invention to be as follows:-
The object of this invention is to fit or arrange certain appliances within the shell
of a burner and in connection therewith, that one part of said shell by a turning
operation shall cause the actual extinguisher appliances to move over the wick or
wicks whether of the single flat, duplex, or circular kind to extinguish the flaine.
The extinguisher appliances are composed of two plates, each with a depending or
other form of leg working in a groove formed in or on ribs of the bottom or fixed
plate of, say, the lower half shell, said groove or rib being eccentric and in length
corresponding to the distance the extinguisher plate has to move.
The top of or extinguishing portions of the two plates are shaped to suit the kind
of wick used in the lamp and instead of the lamp having two extinguisher plates, one
only may be used suitable for a single flat wick.
Instead of grooves being in the bottom plato particularly for a single wick lamp
side levers may be attached for operating the plates.
I purpose making the burner shell with an aperture in the side, through which a
match or taper could be inserted for lighting purposes, a corresponding aperture being
also in a screen or shutter which is operated from one of the plates when moving to
about half its travel, the other half movement closing it up again.

The extinguisher appliances are composed of two plates A, A, cach plate having
depending or other form of leg B working in a groove C formed in or on ribs of a plate D
turnable from the outside, said groove or rib being eccentric and in length corre-
sponding to the distance the extinguisher plates A, A, have to move.
The straight to and fro travel of the plates A is governed by wires E on which the
legs B B rest.
The top of or extinguishing portion of the two plates A A are shaped to suit the
kind of wick used in the lamp.
Figures 1 and 2 show sectional elevation and plan of a burner with the plates A. A.
