PROVISIONAL SPECIFICATION.
Improvements in and connected with Stoves and Furnaces for
Heating, Cooking, and the like.
I, SAMUEL ROW BOTTOM, 82 Abbey Street, Derby, in the County of Derby,
Electrician, do hereby declare the nature of this invention to be as follows:-
My invention relates to an improved apparatus for automatically boiling water
or the like, cooking various articles or lighting gas stoves, ovens, furnaces, &c., it
being capable of being set in action at a given time by means of an alarum clock
and if necessary stopped when the water is boiled and fed to the tea pot or other
vessel.
In carrying out my invention as applied to the boiling of a kettle and the making
of tea, coffee or the like I attach a spindle to the winding portion of an alarum
clock, the said spindle having a tap at the outer end which works in a gas pipe and
controls the supply of gas to the stove, the said gas pipe being attached by rubber
or other suitable connection to the supply pipe, above this tap is a junction from
which a pipe runs having a jet at the end arranged to command the orifices or
burner of a gas stove the latter being supplied with gas by a connection to the gas
pipe immediately below the tap before mentioned.
Upon the gas stove I place the kettle or other vessel for boiling the water the
said kettle being specially constructed for the purpose, having a screw cap in the
top through which is drilled a fine hole or a valve may be fixed in the top of
the kettle; near the bottom of this kettle I attach a pipe arranged to communicate
with or feed the water when boiled into the tea-pot or other vessel, sufficient water
being left in the kettle below the bottom of the pipe to prevent the bottom of the
kettle being burned, and to be used for other purposes.
The tea-pot or other vessel stands upon a suitable plate or tray attached to one
end of a weighted lever pivotted to a bracket, the weight being adjusted to counter-
balance the weight of the water and tea-pot when the latter is full.
Upon the arm of the weighted lever place a suitable stop arranged to engage
with a stop upon an arm attached to the spindle before mentioned.
The apparatus is operated as follows:-I will presume it is wished to set the
apparatus in motion say at 5.30. The kettle having been previously filled, the
alarum set at 5.30, the lid of the tea-pot opened and the tube from the kettle placed
over it; the alarum goes off at 5.30 and rings while the spindle turns a quarter of
a circle the arm on which then stops against the projection on the arm of the
weighted lever; this turning of the spindle turns on the gas at the stove which is
immediately lighted from the gas jet before mentioned the latter being left alight
for the purpose. The water in the kettle becomes heated the steam escaping
through the fine hole in the cap thereof or through the valve and as soon as the
water boils it ascends the tube and passes into the tea-pot into which the tea,
coffee or other substance may have been previously placed. When sufficient water
has passed therein to counterbalance the weight at the other end of the lever the
tray end of the weighted lever falls allowing the stop on the arm attached to the
spindle to become disengaged with the stud on the arm of the lever and the spindle
governed by the alarum apparatus turns another quarter of a revolution, shuts off
the supply of gas to the stove and rings the alarum, thus notice is given both of
the turning on and off of the gas to the stove.
I may attach an electric bell if desired to keep on ringing until the tea-pot or
other vessel is removed.
The pipe which feeds the gas jet or master light takes out any accumulation of
air that may be in the pipe on account of its being always lighted and thus prevents

page_text: tr
flashing back" at the gas stove, a tap may be placed on this pipe to regulate
the jet.
The ordinary stop of the gas tap serves to stop the spindle and the act of turning
back the spindle to the first position winds the alarum."
It is evident that I may apply my invention to a variety of uses, for instance, it
may be applied to lighting any ordinary gas fire, stove, oven or cooker, boiler
furnace heating apparatus, &c. and I may use a stove which will boil and cook at
the same time and arrange to keep back the boiling of the water by placing iron
plates under the kettle or by other suitable means until the articles in the stove are
cooked and thus the whole will be ready at one time.

COMPLETE SPECIFICATION.
Improvements in and connected with Stoves and Furnaces for
Heating, Cooking, and the like.
I, SAMUEL ROWBOTTOM of 82 Abbey Street, Derby in the County of Derby,
Electrician, 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 relates to an improved apparatus for automatically boiling water
or the like, cooking various articles or lighting gas stoves, ovens, furnaces, &c., it
being capable of being set in action at a given time by means of an alarum clock and
if necessary stopped when the water is boiled and fed to the tea-pot or other vessel.
In order that my invention may be the more readily understood I have caused
to be annexed to this Specification a sheet of drawings and to the figures and
letters of reference marked thereon I now refer.
Figure 1 is a back elevation of my improved apparatus as applied to the boiling
of a kettle and the making of tea, coffee or the like.
Figure 2 is an end elevation of same the tea-pot, kettle and gas stove being in
this view omitted for the sake of avoiding confusion.
In carrying out my invention as applied to the boiling of a kettle and the making
of tea, coffee or the like I attach a spindle A to the winding portion of an alarum
clock B, the said spindle having a tap C at the outer end which works in a gas
pipe D and controls the supply of gas to the stove E, the said gas pipe being
attached by a rubber or other suitable connection F to the supply pipe, (the latter
not being shewn on the drawings,) above the tap C is a junction G from which a
pipe H runs having a jet I at the end arranged to command the orifices or burner J
of a gas stove E, the latter being supplied with gas by a connection K to the gas
pipe immediately below the tap before mentioned.
Upon the gas stove I place the kettle L or other vessel for boiling the water,
the said kettle being specially constructed for the purpose, having a screw cap M
in the top or side for re-filling and cleaning purposes; through the top of the kettle
is also drilled a fine hole N or a valve may be fixed therein if desired near the
bottom of this kettle I attach a pipe O arranged to communicate with or feed the
water when boiled into the tea-pot P or other vessel, sufficient water being left in
the kettle below the bottom of the pipe to prevent the bottom of the kettle being
burned and to be used for other purposes.
The tea-pot P or other vessel stands upon a suitable plate or tray Q attached to
one end of a weighted lever R pivotted to a bracket S, the weight T being adjusted
to counterbalance the weight of the water and tea-pot or other vessel P, when the
latter is full.
Upon the arm of the weighted lever R I place a suitable stop U arranged to
engage with a stop V upon an arm W attached to the spindle A before mentioned.

page_text: The apparatus is operated as follows :—
I will presume it is wished to set the apparatus in motion say at 5.30.
The kettle having been previously filled, the alarum set at 5.30, the lid of the
tea-pot opened and the tube from the kettle placed over it; the alarum goes off
at 5.30 and rings while the spindle A turns a quarter of a revolution or there-
abouts, the lever on which then stops against the projection or stop U on the arm
of the weighted lever R, this turning of the spindle turns on the gas at the stove
burner J which is immediately lighted from the gas jet I, the latter being left
alight for the purpose. The water in the kettle becomes heated, the steam escaping
through the fine hole or valve N in the top thereof and as soon as the water boils
it ascends the tube and passes into the tea-pot or other vessel P into which the tea,
coffee or other substance may have been previously placed: (the water is shewn
upon the drawings as being fed into the tea-pot from the top, I may however feed it
down the spout if found desirable). When sufficient water has passed therein to
counterbalance the weight at the other end of the lever R the tray end of the
weighted lever falls, allowing the stop V upon the arm W attached to the spindle A
to become disengaged with the projection, stud or stop U on the arm of the lever R
and the spindle A governed by the alarum apparatus turns another quarter of a
revolution, shuts off the supply of gas to the stove and rings the alarum, thus
notice is given both of the turning 'on' and 'off' of the gas to the stove.
I may attach an electric bell if desired to keep on ringing until the tea-pot or
other vessel is removed.
The pipe H which feeds the gas jet I (or master light) takes out any accumu-
lation of air that may be in the pipe on account of its being always lighted and
thus prevents flashing back' at the stove; a tap may be placed on this pipe to
regulate the jet if desired.
The ordinary stop of the gas tap C serves to stop the spindle A and the act of
turning back the said spindle to the first position winds up the alarum.
It is evident that I may apply my invention to a variety of uses, for instance it
may be applied to lighting any ordinary gas fire, stove, oven or cooker, boiler
furnace, heating apparatus, &c. and I may if desired use a stove which will boil
and cook at the same time and arrange to keep back the boiling of the water, by
placing iron plates under the kettle or other suitable means, until the articles in
the stove are cooked and thus the whole may be ready at one time.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The improved means of automatically turning on the gas and lighting gas
stoves, heating apparatuses or the like at a given time and giving warning of the
same through the medium of the alarum mechanism of a clock, substantially as
described and illustrated.
2. The improved means of automatically heating and cooking various articles,
cutting off the supply of gas and giving warning of the same, substantially as
described and illustrated.
3. The whole substantially as described herein and illustrated by the accom-
panying sheet of drawings.
