PROVISIONAL SPECIFICATION.
Improvements in Safety Spirit Stoves with Regulating Burners.
I EDMUND TOWNSHEND of Glenlee, Church Road, Moseley, Birmingham, in the
County of Worcester, Brassfounder, do hereby declare the nature of this invention
to be as follows:-
The container of my improved spirit stove has within the projecting rim at the
top a lining of cork, so that, when the flange of the lid is pressed home, the container
is hermetically closed in that part and the lid firmly fixed. This is an improvement
over a lid which screws on the container, being casier removed for filling or fixed
when filled and also being spirit tight, which is not the case with the screw arrange-
ment.
In the cover or lid of the stove is a circular trough, so that, if through expansion
of heat or through overfilling the spirit should overflow from the wick hole, the
spirit is caught in this trough and, if ignited, burns harmlessly away, without any
danger of causing a fire.
In the centre of the lid I fix a round metal tube to hold the wick. Round the
upper part of the wick I wrap a piece of copper or other metal gauze. To regulate
the wick I fix a winding spindle in the upper part of the lid above the level of the
spirit, with a spur-wheel fixed on the spindle. This works through a slot in the
wick tube coming into contact with the gauze encircling the wick.
When the spindle. is revolved by means of a disc at one end, the spurs of the
wheel engage with the meshes of the metal gauze, surrounding the wick, and raise
or lower the wick as required.
A great advantage of this arrangement is, that whilst the gauze solidifies the
wick and prevents of its falling sideways, when wound too high, it permits of almost
a complete ignition of the wick. The gauze radiates the heat freely, without con-
ducting the heat into the lid of the lamp to any appreciable extent or making the
winder too hot to be laid hold of by the hand, or by the expansion of excessive heat
causing the spirit to overflow and ignite which is a source of danger.
In order that my invention may be clearly understood I have appended hereunto
a sheet of drawings of the same.

I, EDMUND TOWNSHEND of Glenlee Church Road, Moseley, Birmingham in the
County of Worcester, Brassfounder, 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 :-
The container of my improved spirit stove has within the projecting rim at the

page_text: top a lining of cork, so that when the flange of the lid is pressed home the container
is hermetically closed in that part and the lid firmly, fixed. This is an improvement
over a lid which, screws on the container being easier removed for filling, or fixed
when filled and also being spirit tight which is not the case with the screw 'arrange-
ment.
In the cover or lid of the stove is a circular trough, so that if through expansion
of heat or through overfilling the spirit should overflow from the wick hole, the
spirit is caught in this trough and if ignited burns harmlessly away without any
danger of causing fire.
In the centre of the lid I fix a round metal tube to hold the wick. Round the
upper part of the wick I wrap a piece of copper or other metal gauze. To regulate
the wick I fix a winding spindle in the upper part of the lid above the level of the
spirit with a spur-wheel fixed on the spindle. This works through a slot in the
wick tube coming into contact with the gauze encircling the wick.
When the spindle is revolved by means of a disc at one end the spurs of the wheel
engage with the meshes of the metal gauze surrounding the wick and raise or lower
"the wick as required.
A great advantage of this arrangement is that whilst the gauze solidifies thei wick
and prevents of its falling sideways when wound too high it permits of almost a
complete ignition of the wick. The gauze radiates the heat freely without con-
ducting the heat into the lid of the lamp to any appreciable extent or making the
winder too hot to be laid hold of by the hand, or by the expansion of excessive
heat causing the spirit to overflow.and ignite which is a source of danger.
In order that my invention may be clearly understood 1 refer to the drawing
left with the Provisional Specification.
