JOHN FRANCIS SLEAT 26 Penton Place Kennington Park Road S. W. Engineer
do hereby declare the nature of this invention to be as follows :-
My Invention consists in a combined lamp for burning mineral, and other oils, and
automatic extinguisher for same, and is carried out as follows:-I form the body of
the lamp of a cylindrical or other suitable shape, and insert the same within a sealed
outer containing vessel filled with a fluid which will not support combustion, or the
gases or vapours arising from said fluid when liberated, have the effect of extin-
guishing flame by contact with it. The lamp can be removed from the outer con-
taining vessel for cleaning or retrimming; but should the lamp when replaced be
upset or broken, all danger of fire is averted by the action of the fluid or vapours
arising from it, as described. I provide a special form of sealed perforated stopper in
the outer vessel containing the fluid, which enables me to use it as a sprinkler if
desired.

A Combined Lamp for Burning Mineral and other Oils and
Automatio Extinguisher for same Fitted with Special
Sprinkling Device.
JOHN FRANCIS SLEAT 26 Penton Place Kennington Park Road S.W. Engineer
do hereby declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement
My Invention consists in a combined lamp for burning mineral and other oils, and
automatic extinguisher for same, fitted with special sprinkling device; and is carried
out as follows. I form the body of the lamp of a cylindrical or other suitable shape,
and insert the same within a sealed outer containing vessel filled with a fluid which
will not support combustion; or the gases or vapours arising from said fluid when
liberated, have the effect of extinguishing flame by contact with it. The lamp can be
removed from the outer containing vessel for cleaning or retrimming, but should the
lamp when replaced be upset or broken, all danger of fire is averted by the action
of the fluid, or vapours arising from it as described. I provide a special form of sealed
perforated slopper in the outer vessel containing the fluid which enables me to use it
as a sprinkler if desired.
For the better understanding of my invention, reference is made to the annexed
drawing in which :-
Fig. 1, is a sectional elevation of a lamp fitted with automatic extinguisher, and
sprinkling device.
Fig. 2, an enlarged sectional view of the special form of slopper employed.
Fig. 3, a plan of same.
A Fig. 1 is a lamp of ordinary construction suitable for table use, or when furnished
with suitable suspending mechanism, for hanging up; the body I prefer to make
cylindrical; It can however be made of any shape suited to my purpose; The body of
whatever shape employed is made to fit into an outer containing vessel furnished with
a diaphragm which may be made of glass, stoneware, metal or any substance suited
for my purpose, between the diaphragm B and the external wall of the vessel C, of
which said diaphragm forms a part a hollow space is formed; this space is filled with
a fluid which will not support combustion, or the gases or vapours arising from it
have the effect of extinguishing flame when in contact with it. The base of the
outer containing vessel or some other convenient part is so formed as to receive a
stopper D, which may be screwed, or fastened in any equivalent manner.
stopper I prefer to perforate as shewn at a, a (see also enlarged section Fig. 2. and
plan Fig. 3), a valve b, formed of leather or any suitable substance is fastened by
rivetting or other means to a pintle c, upon one side of which is a projection d, (which
when the valve b, is upon its seat in the stopper and covers the perforations) fits a
corresponding recess in the stopper, this pintle has upon its underside a head or nut e.
The

page_text: The operation of this part of my invention is as follows: The lamp being removed
from the outer containing vessel; the stopper D, is unscrewed and the space between
diaphragm B, and external wall C, is filled with a fluid of the kind described. The
stopper is now screwed in, and the lamp replaced. No fluid can escape, because the
valve b, covers the perforations in stopper D. In case of fire, it is merely necessary
to press upon the nut or button e, at the same time twisting the pintle attached to it,
so that the projection d, may, when the valve is forced off its seat clear the recess
provided for it, and so hold the valve open, by imparting a vibratory motion to the
vessel; sufficient air will enter to enable the fluid to escape in a fine spray or shower,
and by this means a fire can be checked at its outset. In case the lamp itself be
broken the fluid stored in the outer vessel containing it will either directly, or by
the vapours arising from it quench the flame.
Although I have shewn a cylindrical lamp and outer vessel, I do not confine
myself to any special shape or form; & I make no claim for any special liquid,
or fluid, of the class described, what I esteem novel, and desire to secure by
Letters Patent is :-
1st. A lamp for burning mineral and other oils, combined with, and fitted into
an outer containing vessel; furnished with a diaphragın, within which said lamp
fits ; the space between the diaphragm; and outer wall of containing vessel
forming part of it, being filled with a fluid which will not support combustion,
or the gases or vapours arising from which when liberated, will extinguish flame
by contact with it, substantially as described and set forth.
2nd. The combination with a lamp for burning mineral or other oils fitted
within an outer containing vessel, fitted with a fluid which will not support
combustion, of a special form of sealed perforated stopper, screwed or otherwise
fastened into said vessel constructed as described, for the purpose of enabling said
outer containing vessel to be used as a sprinkler, substantially as set forth.
3rd. The particular arrangement of parts described for stopper D, the per-
forations a, a, valve b, pintle c, having projection upon it d, and corresponding
recess in material of stopper; the whole combined and operating together for the
purposes set forth.
