PROVISIONAL SPECIFICATION.
An Improvement in the Construction of Gas Stoves.
We GEORGE RICE of No. 3 Oliver Street Kingsley Park, Kingsthorpe
Northamptonshire Gas Fitter, and JOHN WOODING of No. 121 Clare Street
Northampton, Shoe Manufacturer do hereby declare the nature of this invention
to be as follows:-
The object of our invention is to construct an extra top or plate to gas stoves of
the required shape and size having lever and crank attachments which connect it
with the supply tap and which may be adapted in the construction of new stoves,
or may be fitted as an improved addition to existing stoves, the said extra top or
plate acting as a self regulator to the supply tap so that when the stove is in
use the required gas passes through the supply tap, and when the stove is not
in use, only sufficient gas is allowed to pass through the supply tap that will
give a small light sufficient to withstand ordinary draughts, the amount of gas
in both cases being under control by extra taps or plugs; the said extra top
or plate acting automatically as a self regulator to the stove, thus doing away
with the trouble of continually turning on and off the supply tap and relighting
the burner, as is the case with existing stoves consequently a considerable
reduction in the consumption of gas is effected, at the same time greatly reducing
the heat engendered by the stove when not in use, which is of great importance
where a number of operatives work together in one room.
In carrying out our invention we proceed as follows, We provide and form
into the required shape and size a metal plate, which is fixed over the burner
by means of a flap hinge or in any other suitable way at one end only and
this end of the aforesaid plate is connected by means of levers and a crank to
the thumb-bit of the supply tap of the stove the weight of the levers and crank,
being sufficient to raise the free end of the aforesaid plate some distance from
the burner and when an iron, or any other tool or utensil is placed upon the
plate, the plate immediately drops into a flat or horizontal position and by a
combined action of the aforesaid levers and crank the supply tap is turned on
at the same time, and when the iron, tool, or utensil is taken off the free end
of the plate rises, and is secured in position by a metal stop the levers and
crank turning the supply tap nearly off at the same instant.

An Improvement in the Construction of Gas Stoves.
We GEORGE RICE, of 3 Oliver Street, Kingsley Park, Kingsthorpe, in the
County of Northampton, England, Gas Fitter, and JOHN WOODING, of 121 Clare
Street, Northampton, aforesaid, Shoe Manufacturer, 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 object of our invention is to construct mechanism, that will automatically

page_text: control the supply tap of gas stoves, of principally that class which are known
as shoemakers or bookbinders finishing stoves, so that when in use the required
quantity of gas may pass through the supply tap, but when not in use the tap
is turned nearly off, and only enough gas is allowed through it, that will give
a small flame light sufficient to withstand ordinary draughts.
But in order that our invention may be better understood reference is made
to the accompanying drawings, in which Figures 1 and 2 illustrate respectively,
an elevation and plan of a gas stove.
Similar letters of reference indicate similar or corresponding parts where they
occur in both views.
In the drawings (A) represents the frame of an ordinary shoemakers or book-
binders finishing stove, having the two wings or leaves (B) and (B) and
aperture (C); (D) is the gas burner, and (E) is the supply tap to which is
fitted the nipple (F) to receive one end of a flexible tube.
In carrying out our invention we hinge to the upper part of the frame (A)
one end of a metal plate (G) made of a corresponding shape to the frame
beneath it. Said plate (G) is provided with two end pieces (H) and (I),
one of which lettered (1) carries a longitudinal lever (J) which connects by a
link (K), with an arm or crank (L) secured to the thumb-bit or socket (M) of
the supply tap (E). (N) is a slot formed in said lever, in which the threaded
portion of the check piece (0) may be adjusted, for regulating the movement
of the lever and supply of gas.
a
It will thus be seen that, by placing say, a tool, or other weight on the hinged
plate (G), the effect will be, that said plate and lever (J) will assume
horizontal position, the action of which causes the supply tap (E) to be turned
on, so that the required amount of gas may pass through it. When, say the
tool, is removed the plate immediately returns to its normal position, as illustrated,
by reason of the lever being balanced slightly heavier than the plate, thus
causing the supply tap to be turned nearly off, and allow only sufficient gas to
pass, that will give a very small flame light.
For regulating the supply of gas to the stove, we insert in the tap (E) a
small screwed valve (P), which can be adjusted, according to the amount of gas
required.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
Firstly. In stoves such as described, the combination and arrangement with a
frame similar to (A), of the hinged plate (G) substantially as and for the
purposes herein set forth and as illustrated in our drawings.
Secondly. In stoves such as described, the combination and arrangement with
the hinged plate (A) of the lever (J), link (K) and crank (L) together with
the check piece (0) substantially as and for the purposes herein set forth and as
illustrated in our drawings.
Thirdly. In stores such as described, the combination of the various parts,
arranged to automatically control the supply of gas, substantially as and for
the purposes herein set forth and as illustrated in our drawings.
