Improvements in Extinguishers for Hydro-carbon and other
Oil Lamps.
I FRANCIS ROBERT BAKER of Snow Hill, Birmingham in the county of Warwick
Engineer do hereby declare the nature of this invention to be as follows:-
This invention relates to an arrangement or contrivance for the quick and ready
extinguishing of oil lamps at will, and the automatic extinguishing of such lamps
when by accident &c. they may be overturned.
It consists primarily of a sliding case (single wick) or cases (two or more wicks)
having at the upper end a flap or shutter similar to those already in use, such case or
cases being made to slide, and shutter to close by reason of the gravitating action of a
loose rolling ball weight or weights, and being further provided with a arm extending
to the outside of the lamp, so as to be manipulated at will, or, that when such lamps
should, by accident or otherwise be overturned, and thereby liable to take fire or
explode, the flame may be quickly extinguished before such damage can be done.
In carrying out my invention I proceed somewhat thus:-I provide a sliding case
similar to those at present in use, to work freely upon the exterior of the wick tube,
having a flap or shutter hinged at its upper part, so that when the case is raised or
slid above the burning wick, the said flap may fall over and cover or encase it within
itself.
Provision is made upon this sliding case to carry one or more ball weights. This
may be done by attaching a tube or tubes thereto, having at its lower extremity a
bottom or end. In this tube or tubes I place a heavy (lead) ball. At the upper part
of the sliding case the flap is hinged so that its tendency is always to fall across the
flame when passed above it. At the upper end of the tube wherein lies the ball I
provide either a separate little hinged flap, for the ball (when upset) to strike against,
and which then by its weight, together with the momentum created by its velocity,
carries the sliding case forward, at the same time acting upon and closing the flap over
the flame as before described, or, there may be a projection upon the flap itself that
the ball may strike against direct with similar results.

page_text: To this sliding case in some instances however, I may form a ledge near its bottom
part, the said case having underneath it a spring or springs tending to raise it. Upon
this ledge I may place the ball or balls, which would keep the sliding case down
against the pressure of the spring. Provision would then be made so that the ball or
balls may roll off such ledge when the lamp was overturned, leaving the spring then
free to act and raise the extinguisher. When the sliding case was again lowered (by
hand) the balls would fall again on to the said ledge, thus righting itself for re-action.
To these sliding cases a arm may be secured, which passes to the outside, so that the
said case may be raised or lowered at will, when the flame would be extinguished as
before described.

I FRANCIS ROBERT BAKER of Snow Hill, Birmingham in the county of Warwick,
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 :-
This invention relates to an arrangement or contrivance for the quick and ready
extinguishing of oil lamps at will, and the automatic extinguishing of such lamps when
by accident, &c., they may be overturned.
It consists primarily of a sliding case (single wick), or cases, (two or more wicks)
having at the upper end a flap or shutter similar to those already in use, such case or
cases being made to slide, and shutter to close, by reason of the gravitating action of
a loose rolling ball weight or weights, and being further provided with an arm
extending to the outside of the lamp, so as to be manipulated at will, or, that when
such lamps should by accident or otherwise be overturned and thereby liable to take
fire, or explode, the flame may be quickly extinguished before such damage can be done.
In carrying out my invention I proceed somewhat thus :-I provide a sliding case,
similar to those at present in use, to work freely upon the exterior of the wick tube,
having a flap or shutter hinged at its upper part, so that when the case is raised or
slid above the burning wick, the said flap may fall over and cover or encase it within
itself.
Provision is made upon this sliding case to carry one or more ball weights. This
may be done by attaching a tube or tubes thereto, having at its lower extremity a
bottom or end. In this tube or tubes I place a heavy ball. At the upper part of the
sliding case the flap is hinged so that its tendency is always to fall across the flame
when passed above it. At the upper end of the tube wherein lies the ball, I provide
either a separate little hinged flap, for the ball, when the lamp is upset, to strike
against; or, instead of this separate little hinged flap, (and this following arrangement
I prefer to adopt, that is to say) I provide a projection upon the flap itself, which may
be formed, by extending the lower part of the said flap into a suitable shape against
which the ball may strike direct, the whole (the ball, sliding case and tube) then sliding
forward by reason of their weight and momentum, and closing the flap over the flame
as before described.
Having now described the nature of this my invention, I will proceed to more clearly
ascertain the manner in which it is to be performed, with the aid of, and reference to,
the accompanying sheet of drawings upon which are figures and letters of reference,
and upon which like letters refer throughout the several views to the same thing or
part.
Fig. 1 is a part sectional elevation of a burner (single wick) with extinguisher
attached.
Fig. 2 is a plan of the burner and extinguisher, with the gallery and cone removed.
Fig. 3 is a side sectional elevation of Fig. 1, shewing normal position of extinguisher,
with the ball weight at rest.
Fig. 4 shows an assumed position of the burner, when it may have been overturned.
Fig. 5 is a detailed front view of the extinguisher slide.
Fig. 6 is a side view of Fig. 5.

page_text: a, is the wick tube, b is the body of the burner, c is the cone, d is the gallery or
glass holder, e is the wick winder, fis the junction part of the burner, which is screwed
or otherwise fastened to the reservoir of the lamp, g is the cap of the burner.
Upon the wick tube I provide a sliding case h, to work freely upon the said tube,
having at its upper part a flap or shutter i, hinged or swivelled at j, the upper part
of the said flap being out of the perpendicular with the hinge, so that its tendency by
reason of its weight, (when raised by hand) is always to fall across the wick tube, and
cover or encase the flame of the wick.
I further make provision upon the sliding case, to carry the ball weight, 1. To the
said sliding case I attach the tube m, by soldering or otherwise, so that it becomes as
one piece with the said sliding case, and slides therewith. At the lower part of the
flap i, I provide the projection or extension n, which stands across the upper part of
the tube m, in the pathway of the ball, when the latter rolls along the said tubes by
reason of its having been overturned; at the front of the tube I may make a
slot o, for the projection n to fall into.
It will now be readily seen, particularly by referring to Fig. 4, that upon the lamp
being capsized, the ball 7 rolls forward along the tube m, thus altering its relative
position from the bottom towards the top of the burner, when it comes in contact with
the projection n, and all (the ball, sliding case, and tube) by reason of their weight
slide or move forward, until the shutter is carried beyond the top of the wick, when
the weight of the ball closes it over the wick, effectually extinguishing its flame.
Upon the lamp being righted (upright) the sliding case falls back into its normal
condition, the several parts assuming their respective relative positions, again ready
for use.
In order to use this extinguisher by hand, at will, I provide an arm or extension
piece p, connected to, and as in one with the sliding case, to pass through a slot in the
body of the burner, to the outside, and there terminating at q, with a suitable tip
or end.
Upon pushing this arm p upwards in the direction of the arrow, the case h, readily
slides upwards, when the flap i falls over as before described, and with the same
results.
Although I have illustrated and described this my improved method of extinguishing
lamps, as applied to a single wick lamp, I may readily adapt it to lamps of two or
three wicks, inasmuch as it would only require a modification in construction, and in
such cases,
may use one or more tubes m, with it, or their ball weights 1; and have
separate sliding cases h, for each wick, or, combine them into one, as will be most
convenient.
Having thus particularly described and ascertained the nature of this my said
invention, and in what manner the same is to be performed, 1 declare that what I
claim is:-
1st. The extinguishing of hydro carbon and other oil lamps, when accidentally or
otherwise overturned, by means of a loose rolling ball weight, or ball weights, within
tubes or guides, acting upon the flap or shutter of a sliding case, in order to close it over
the flame of such lamps similarly as herein described, and illustrated upon the drawings.
2nd. The general arrangement and combination of the parts constituting the
extinguishing apparatus, that is to say, of the sliding case and tubes or guides, the
rolling ball or balls, the overhanging hinged flap or shutter, and the arm or extension
piece p, each and all substantially as, and for the purposes hereindescribed, and
illustrated.
