page_text: Improvements in Ovens Used for Roasting, Baking, and Cooking,
and for other Purposes for which Ovens are Used.
We GEORGE HENRY LEECH of 20 and 22 Old Millgate Manchester in the
County of Lancaster and JAMES HENRY HOYLE of the same place Furnishing
Ironmongers do hereby declare the nature of our invention for IMPROVEMENTS
IN OVENS USED FOR ROASTING BAKING AND COOKING AND FOR OTHER PURPOSES
FOR WHICH OVENS ARE USED a communication to us from abroad by Robert Leech
of 20 and 22 Old Millgate Manchester in the county of Lancaster but at present
travelling in the United States of America Furnishing Ironmonger and in what
manner the same is to be performed to be particulary described and ascertained in
and by the following statement :-
This invention relates to ovens used for roasting, baking and cooking and for
other purposes for which ovens are used and this invention consists in providing
each of the said ovens with an extra door in addition to the door ordinarily
employed in such ovens, which extra door is attached to the oven to which it is
applied by means of hinges or in any other suitable and convenient manner and
which extra door is so formed that air may readily pass into and out of the interior
of the oven to which such extra door is applied.
In carrying this invention into effect we form or provide the extra door above-
mentioned with a number of perforations or we form such extra door aforesaid of
wire-gauze or wire-netting or of perforated metal or other suitable material provided
with perforations.
In order that our invention may be thoroughly understood and carried into effect
we have hereunto annexed a sheet of drawings, in which Fig. 1 is a front view and
Fig. 2 is a plan partly in section of so much of an oven as is necessary to illustrate
our invention Similar letters of reference are applied to corresponding parts in
both of the figures-In Figs. 1 and 2 a is the extra door which is supported by and
capable of being turned upon pivots b. c carried respectively by brackets d. e. secured
to the framework f. of the oven-The extra door a is held in position to close the
entrance to the oven by means of the latch 9 which acts in conjunction with a
catch h secured to the framework f. j is the ordinary door of the oven which
ordinary door j is supported by hinges k. I capable of being turned upon the studs
b. c. respectively.
The door j is held in position to close the entrance to the oven by means of the
latch m acting in conjunction with a catch n secured to the framework f of the
oven. The extra door a is provided with a number of perforations by having an
opening formed through it and covered with wire-gauze o which we secure to the
extra door a by placing such wire-gauze o in a recess formed in the said extra door a
and securing such wire-gauze o in the said recess by means of a frame p secured to
the extra door a by means of screws q-In Fig. 1 a portion of the door j is shown
as being removed in order to show a portion of the extra door a and wire gauze o.
When the door ; and the extra door a are in the positions in which they are shown
in the drawing the oven may be used as an ordinary oven. By turning the door j
upon the pivots b. c into the position indicated by the dotted lines A in Fig. 2 and,
leaving the extra door a in the position in which it is shown, air will be allowed
гј

page_text: to enter the oven and escape from the interior of the oven through the interstices
of the wire-gauze o so that a circulation of air will be caused to take place in
the interior of the oven-Such circulation of air will produce an effect upon
the meat or other material roasted baked or cooked in the oven similar to the
effect produced upon meat or other material roasted baked or cooked in front of a
fire. In cases in which it is not desired to employ an ordinary door in addition to
the extra door provided with perforations we employ the arrangement shown in
Figs. 3 and 4 in which Fig. 3 is a front view and Fig. 4 is a plan partly in section
of so much of an oven as is necessary to illustrate this method of carrying our
invention into effect. In Figs. 3 and 4 r is the door of the oven which is supported by
means of hinges a. t. capable of being turned respectively upon the studs u. v carried
respectively by brackets cc. y secured to the frame-work z of the oven-Through the
door we form an opening 1 which we cover with wire gauze 2. which wire gauze 2 we
retain in position over the opening 1 by means of a cap or cover 3 which is secured
to the door by means of nuts 4 and screwed pins 5-The door r is held in position
to close the entrance to the oven by means of the latch 6 which is capable of being
turned upon a pivot 7 attached to the cover or cap 3 and acts in conjunction with
a catch 8 We form perforations 9 through the cap or cover 3. In Fig. 3 a portion
of the cap or cover 3 is shown as being removed in order to show a portion of the
wire gauze 2-The external air has access to the interior of the oven by means of
the perforations 9 and the interstices of the wire-gauze 2 while the air in the
interior of the oven can escape therefrom through the interstices of the wire-gauze 2
and the perforations in the cap or cover 3-During the process of roasting baking
or cooking meat or other material in the interior of the oven the external air will
pass through the perforations 9 and through the interstices of the wire-gauze 2 into
the interior of the oven and at the same time air will escape from the interior
of the oven by means of the interstices of the wire gauze 2 and the perforations 9
into the external air.
The circulation of the air thus produced in the interior of the oven during the
process of roasting baking or cooking meat or other material will produce an effect
upon the said meat or other material similar to the effect produced upon meat or
other material roasted baked or cooked "before the fire."
In Figs. 3 and 4 we have shewn the wire-gauze as being protected by a cap or
cover 3 but we in some cases dispense with the cap or cover 3.
In such cases the wire-gauze may be secured to the door of the oven in any
suitable manner.
.
Although in Figs. 1. 2. 3 and 4 of the drawing hereunto annexed and in reference
thereto we have shewn and described wire-gauze as being employed we would have
it understood that instead of such wire-gauze wire-netting perforated metal or other
suitable material provided with perforations may be employed or perforations may
be formed in the extra door employed.
We have hitherto referred to the wire-gauze or perforated metal or material or
perforations as being placed or formed in the door of the oven only but we would
bave it understood that the perforated metal or material or perforations may be
placed or formed in any other part of the oven provided that the air on the
outside of the oven may pass into the interior of the oven and the air in the interior
of the oven may pass out from the interior of the oven.
Although in the drawing hereunto annexed we have only shown two methods of
carrying our invention into effect we would have it understood that we do not
confine ourselves to such methods of carrying our invention into effect as the said
invention may be carried into effect in a number of ways.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is:-
1. In an oven for roasting baking or cooking meat or other material means
whereby air is allowed to enter and escape from the interior of the oven which

page_text: means consist in perforations wire gauze or wire netting or perforated metal or
other material provided with perforations; formed or placed in the said oven
substantially as and for the purposes hereinbefore described and shown.
2. In an oven for roasting baking or cooking meat or other material in addition
to the ordinary door employed an extra door formed with perforations or provided
with wire gauze wire netting or perforated metal or other material provided with
perforations substantially as hereinbefore described by means of which perforations
air may pass into and escape from the interior of the said oven in the manner and
for the purposes hereinbefore described and shewn.
3. In an oven for roasting baking or cooking meat or other material a door
formed or provided with perforations formed therein or provided with wire gauze
wire netting or perforated metal or other material provided with perforations sub-
stantially as and for the purposes hereinbefore described in reference to and shown
in and by Figs. 3 and 4 of the drawing hereunto annexed.
