-
One of the great disadvantages attending the use of gas cooking stoves as at
present constructed is the fact that the gas is frequently left burning after the
cooking is finished thereby causing great waste moreover by the oven tap being
accidentally turned on when not required explosions are frequently occasioned.
Now my invention relates to improvements in gas cooking stoves whereby the
gas supply is automatically cut off on the removal from the oven of the joints or
other articles being cooked and cannot again be turned on unless a joint or other
article be placed in the oven; means are however provided whereby the supply of
gas can be turned on if it is required to merely heat the oven.
In carrying out my invention the shelves of the oven of the gas cooking stove
are balanced for which purpose they may be supported on suitable weighted
uprights moving on suitable fulcrums. The plug of the ordinary gas cock is
formed with a continuation which extends into the oven and which continuation
is provided with an arm operated by a rod or projection on one of the frames
supporting the shelves in such a manner as to cut off the supply of gas from the
supply pipe on the removal of the joints or the like from the shelves of the oven;
the shelves on being relieved from the weight will (on rising), by means of the
said rod or projection operate the arm on the gas cock so as to close the same and
keep it closed.
On a joint or the like being again placed upon the shelves of the oven the
shelves will be depressed and will release the rod or projection from contact with
the arm on the gas cock which can then be turned on or regulated from the outside.
of the oven in the usual manner.
In order to allow of the gas being turned on for the purpose of heating the oven
I provide a bolt or other catch fastening on the frame of the oven by which the
shelves can be secured in their depressed position (so long as the door of the oven
is not quite closed) so as to turn on the supply of gas, the said bolt or the like
being so arranged as to be released on the door of the oven being closed.

Berks, Gas Stove Manufacturer do hereby declare the nature of my said invention.
for "IMPROVEMENTS IN GAS COOKING STOVES" and in what manner the same is
to be performed to be particularly described and ascertained in and by the
following statement :-
One of the great disadvantages attending the use of gas cooking stoves as at
present constructed is the fact that the gas is frequently left burning after the
cooking is. finished, thereby causing great waste, moreover, by the oven tap being
accidentally turned on when not required, explosions are frequently occasioned.
Now my invention relates to improvements in gas cooking stoves whereby the
gas supply is automatically cut off on the removal from the oven of the joints or
other articles being cooked, and cannot again be turned on unless a joint or other
article be placed in the oven; means are however provided whereby the supply of
gas can be turned on if it is required to merely heat the oven.
In carrying out my invention the shelves of the oven of the gas cooking stove
are balanced, for which purpose they may be supported on suitable weighted
levers moving on suitable fulcrums. The plug of the ordinary gas cock is provided
with an arm or is formed with a continuation which extends into the oven, and
which continuation is provided with an arm in either case the arm being operated
by a rod or projection on one of the bars of the frames supporting the shelves, in
such a manner as to cut off the supply of gas from the supply pipe on the removal
of the joints or the like from the shelves of the oven; the shelves on being relieved
from the weight will, (on rising) by means of the said rod or projection, operate the
arm on the gas cock so as to close the same and keep it closed.
On a joint or the like being again placed upon the shelves of the oven the
shelves will be depressed and will release the rod or projection from contact with
the arm on the gas cock, which can then be turned on or regulated from the
outside of the oven in the usual manner.
In order to allow of the gas being turned on for the purpose of heating the oven
I provide a bolt or other catch fastening on the frame of the oven, by which the
shelves can be secured in their depressed position (so long as the door of the oven
is not quite closed) so as to turn on the supply of gas, the said bolt or the like
being so arranged as to be released on the door of the oven being closed.
In order to enable my invention to be fully understood I will proceed to describe
the same by reference to the accompanying drawing in which figure 1 sheet 1
represents a front elevation and figure 2, sheet 1, a side elevation of a gas cooking
stove constructed according to my invention, the door of the oven being removed
for the sake of clearness; the shelves of the oven of the stove are shewn secured
in their depressed position by the bolt or catch, with the gas cock turned on; in
the said figures the arm operating the gas cock is placed within the oven; figure 3,
sheet 1, is a detached sectional view on a larger scale shewing the shelves in their
raised position and the gas cock closed. Figure 4 sheet 2 is a part front elevation

oven; figure 5, sheet 2, is a side elevation of figure 4, sheet 2, and, figure 6 sheet 2,.

parts.
In sheet 1, A represents the oven of the gas cooking stove and B is the usual
pipe for supplying gas to heat the same; c, c, c, are the shelves of the oven pivoted.
at d, d, d, at the back of the oven; the shelves c, are connected together at their
front ends by means of a vertical bar e, jointed to each side thereof at f, ƒ ƒ ;
g, g, are bars fixed at each side of the front of the oven and provided with guide
slots h, in which slide guide pins i, on the front of the shelves c; to the bars e are
attached rods k, k¹, which are connected at 1, 1 to one end of the weighted levers m,
moving on the fulcrums n; o, o are the weight of the levers m; j, is the con-
tinuation of the plug of the ordinary gas cock p, which continuation extends into
the oven as shewn in dotted lines in figure 1; q, figure 3 shews the arm of the
continuation j, of the plug of the gas cock; is the projection on one of the rods k,
attached to the bar e, which projection r, operates the arm q on the gas cock as
hereinafter described.
8 is the bolt or catch on the frame of the oven for securing the shelves in their
depressed position as shewn in figures 1 and 2, by being drawn forward under a
pin or projection t, at the side of the oven; a suitable projection is provided on the
door of the oven for pushing back and releasing the bolt s, when the door is
closed.
By these improvements, when a joint or the like is placed on the shelves c, of
the oven, they will be depressed and will occupy the position shewn in figures 1
and 2, and the projection being thereby removed from contact with the arm q,
on the gas cock P, the latter can be turned on as shewn, or regulated from the
outside of the oven and the door of the oven being closed the bolt s, will be forced
back out of contact with the pin or projection t; on the removal of the joints or
the like from the shelves c of the oven, the shelves c and bars k and k¹ will be
raised by means of the weighted levers m into the position shewn in figure 3; thé
bar k, in rising will, by means of its projection r operating the arm q, automatically
cut off the supply of gas from the supply pipe B, by closing the cock p; if it is
required to turn on the gas (when no joints or the like are on the shelves of the
oven) for the purpose of heating the oven it is only necessary to depress the
shelves c, and draw forward the bolt s, as shown in figures 1 and 2 by which
the shelves will be secured in their depressed position (so long as the door of
the oven is not quite closed) and the supply of gas can then be turned on.
Instead of employing a bolt 8, as shown in the drawing for securing the
shelves c, in their depressed position, I sometimes secure them by merely drawing
out one of the shelves c, of the oven which is arranged to bear against any suitable
projection or projections on the front of the oven, the said shelf being forced back
in a similar manner to that herein before described for the bolt.
•
The arrangement shewn in sheet 2, is similar to that herein before described and
shewn in sheet 1, except that the arm q, is situated on the plug of the gas cock
outside the oven and the projection r, is formed on a rod a¹, fixed to one of the
rods k. The operation is substantially the same as that hereinbefore described
when referring to sheet 1, and will therefore be well understood without further
description.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed I declare that what
I claim is
1. A gas cooking stove constructed in such a manner that the gas supply shall
be automatically cut off on the removal from the oven of the joints or other
articles being cooked, and cannot be turned on again unless a joint or other article
be placed in the oven, substantially as hereinbefore described.

page_text: 2. The combination with a gas cooking stove constructed as above claimed of an
arrangement whereby the supply of gas can be turned on, if it is required to
merely heat the oven, so long as the door of the oven remains open, substantially
as herein before described.
3. In a gas cooking stove the combination with an oven having balanced shelves,.
of a gas cock the plug of which is adapted to be operated by a projection or rod
upon the frame of the oven, substantially as and for the purposes hereinbefore
described and represented in the various figures of the accompanying drawings.
4. The herein described arrangement for securing the shelves of the oven in
their depressed position when required such arrangement consisting of a bolt on
the frame of the oven, which bolt can be passed under a pin or projection at the
side of the oven and is arranged so as to be released on the door of the oven being
closed substantially as and for the purpose hereinbefore described and represented
in sheet 1 of the accompanying drawings.
5. The improved gas cooking stoves hereinbefore described and represented in
the accompanying drawings.
