Improvements in the Construction of Gas Cooking Appliances.
1, WILLIAM HENRY MIOKLETHWAIT, of Clough Works, Clough Road, Rotherham,
in the County of York, Ironfounder do hereby declare the nature of this invention
to be as follows:-
My invention consists in certain improvements in the construction and arrangement
of the ovens, and other parts, in gas cooking appliances, whereby they may be easily,
rapidly, and securely fitted together, or taken apart as desired, by unskilled labourers;
the various parts of same may be warehoused, or packed for export or transit, in
much sinaller compass, and with greater security than when fitted together, and the
cooking arrangements in certain details, are more complete and efficient than in gas
cooking appliances in ordinary use.
To accomplish this, I form the bottom sides, back, top, and other parts of the oven,
of separate castings; certain of which may be hollow, for conveying the heat
round the oven, and all, or any of which may be packed with any non-conducting
material, to prevent loss of heat by radiation.
The various sectional parts of these ovens are furnished with certain flanges, slots,
hooks, keys, latches, and thumb-pieces, so arranged, that when these sections are fitted
together, they are readily and firmly secured, without the necessity of employing
screws, tie-bars, bolts, or rivets, as is usual in the construction of ordinary gas ovens.
These hooks, keys, latches, and thumb-pieces, may be made of any suitable material,
but preferably of wrought or malleable iron. cast in, or otherwise fixed or fitted to
the various parts, as, and where required; and are so arranged, that while the various
sections are held securely in position thereby, or are readily taken apart; the fixings
are so secured, or so secure one another, that they cannot be unfastened by accident,
or unless so desired.
My invention also consists of an arrangement for hanging, or securing the slides
which support the oven shelves, by means of wrought iron or other hooks, cast
in, or otherwise fixed to the inner sides of the oven; whereby the said slides are
removeable at pleasure, and they, as also the ovens are thereby more easily and
thoroughly cleaned.
My invention also consists of an improved method of holding in position the
drip pan or grid in connection with the grilling apparatus, at any required distance
from the burners, at pleasure; by means of a strip, or plate, or pillar, as preferred,
fixed to, or fitted to the top of oven (if an oven be under the grill); said strip, or
plate, or pillar, having holes, or notches, of any required shape, and at such distances
apart as may be required, for regulating and holding in position, the drip-pan and
grid, either separate or combined.
My invention also provides for a removeable plate or tray, placed under the grilling
apparatus, and on top of the oven, to facilitate cleaning operations, by preventing
grease or other deposit, from lodging on top of oven; said plate or tray being
provided with supports or slides as preferred, to keep it clear of, and easily removed
from top of oven.
Certain of these arrangements, with modifications to suit the altered conditions
may also be applied to other gas grilling stoves or ovens, either separately or
combined.

Improvements in the Construction of Gas Cooking Appliances.
I, WILLIAM HENRY MICKLETHWAIT of Clough Works, Clough Road, Rotherham
in the County of York, Ironfounder, 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 :-
t
My invention consists in certain improvements in the construction and arrange-
ment of the Ovens and other parts of Gas Cooking Appliances, whereby they may
be easily, rapidly and securely fitted together, or taken apart as desired; the various
parts of saine, may be warehoused, or packed for export or transit, in much smaller
compass and with greater security than when fitted together; and the cooking
arrangements in certain details, are more complete and efficient than in Gas Cooking
Appliances in ordinary use.
To accomplish this, I form the bottom sides, back, top, and door of oven of
separate castings; certain of which may be hollow, and all or any of which may be
packed with any non-conducting material to prevent loss of heat by radiation. These
sectional parts are fitted with flanges sockets, bolts and latches, in such a way that
they are readily and firmly secured by interlocking, and the use of screws, tie-bars,
or rivets for fixing these sections together may be entirely dispensed with.
My invention also consists of an arrangement for hanging or securing the slides
which support the oven shelves, by means of projecting hooks fixed in convenient
positions on the inner sides of the oven so that they can be easily removed, and as
well as the oven be thoroughly cleaned.
These slides may be made preferably in sets and on frames, so that say two
projecting hooks may support all the slides on one side of the oven.
My invention also consists of an improved method of holding in position
the drip pan or grid in connection with the grilling apparatus at any required
distance from the burners, by means of a strip or plate or pillar, having holes or
notches of any required shape for holding the drip pan or grid in any required
position.
My invention also consists of a removeable plate or tray placed under the
grilling apparatus, and on top of the oven, to prevent grease or other deposit
from lodging on top of oven. This plate or tray is raised clear of the top of the
oven by means of rails or slides, so as to provide for the plate or tray being
readily removed.
And in order that my invention may be thoroughly understood, I append hereto
one sheet of drawings containing nine Figures and showing in detail the various
features of my invention. In these Figures, the same parts in each, are indicated by
similar reference letters.
Figure I shows a front elevation of my improved gas cooker, with the oven door
removed.
Figure II shows a side elevation of same.
Figure III shows the base of same on plan and a portion of the sides. and back
in section. In these Figures the details C. C. C. D. D. D. E. E. & G. G. show the
arrangements for fixing and interlocking the sides and back to the base and top,
and B. B. in Figure III shows how the flanges at back of the sides clasp and secure
the back to sides.
D. D. D are hooks or bolts at bottom of sides and back, which pass through or into
holes or recesses C. C. C. in base; which holes or recesses are sufficiently large, and so
shaped as to pass the hooked heads of bolts D. D. D. and when the sides and back are
drawn endways into position, the bolts or books D. D. D. lock into the holes C. C. C.
and hold the sides and back securely to the base. The top is fixed to the sides by
means of hooked bolts F.F. shown in Figures IV & V, which are secured to under
side of top, and pass through the top edges of sides, where they are locked and held
in position by sliding bolts E. E. as shown in enlarged detail in Figures IV and V.

as shown in Figures I & II and in enlarged detail in Figure VI.
The bolts F. F. and E. E. are shown in a back view elevation, and in enlarged
detail in Figure IV; and Figure V shows a plan of the same in enlarged
detail.

In Figures I and III I show my improved removeable slides A A for supporting
oven shelves. These are made preferably in sets, and cast or fixed on
frame so that the entire set of slides for each side is combined on

as shown on Figure I. which pass through corresponding holes or under convenient
cross bars in the frames, from which the frames are suspended and held in
position. These frames may be removed at pleasure by being lifted off the
hooks N.N, and the cleaning of the slides and interior of the oven is thereby much
simplified.
Figures VII, VIII & IX illustrate details of my improved arrangement for
grilling. In Figure VII a plate or tray J is shown which rests on two raised
rails or slides H H cast on, or fixed to the top of oven, as shown also in Figures I, & II,
which keep the plate or tray J clear of the top of oven.

from reaching and lodging on top of the oven, and facilitates the keeping of
same clean.
In Figure VIII I show an elevation and plan of a plate K which may be fixed by
means of screws or otherwise to the top of oven, behind the rails H If. I show an
alternative arrangement in Figure 1X to the plate K in the pillar M which may be
fixed by a socket in like position, and in either of which are a series of holes P. P. of
any desired shape, which receive a corresponding projection or tooth on the frame L
shown in Figure IX. This frame L is a support for the grid which it keeps in position
at any required distance from the grilling Hame.
I do not confine myself strictly to the details given in the foregoing description
of my invention, as they may be modified or varied to meet the exigencies
of particular cases or tastes, so long as the essential principles of my invention are
adhered to.
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 arrangement for securing or locking together, the various sections of my
Gas Cooker, as described and illustrated by the accompanying drawings.
2. The arrangement for providing removeable slides for supporting oven shelves,
as described and illustrated by the accompanying drawings.
3. The arrangement for holding in position, the drip pan or grid for grilling
pparatus, as described and illustrated in accompanying drawings.
4. The removeable plate or tray under grilling apparatus, all as described and
llustrated by accompanying drawings.
