the same being Usually Known as Hot-air Ovens.
We, EDWARD REDMAYNE MORPHET, of Duke Street, Settle, Yorkshire, Ironmonger,
and JOHN HARDY of Craven Cottages, Settle aforesaid, Mason, do hereby declare the
nature of this invention to be as follows, that is to say :-
It consists of improvements in the construction of ovens for domestic purposes
whereby the hot-air or other gases that heat the same are more uniformly distributed
over its outer surface with the obvious result of raising the temperature of its entirety
with the same degree of uniformity throughout.
To accomplish this we construct and so place or fix the said oven that when it is
required to be heated, by a valve or "damper" being removed so as to open the vent
or flue, the heated air, or other gases, from the fire pass under the bottom, up the side,
over the top, down the other side, out of an opening at the bottom back corner
thereof, around to, and up out at the back of the said oven.
This being achieved by placing the oven on the usual brick work supports so as to
leave its bottom outer surface open to the action of the heated air or gases.
Again the flue is made so that the whole surface of one side is also open to the
action of heated air, so also is the top and the other side, however by a suitable
partition or stop piece being placed on the said top part about midway between its two
sides and extending from the back edge thereof to about its centre part, the current of
heated air or gases instead of going in the shortest direction to the opening at the
bottom back corner before mentioned, is turned aside and brought to pass more
towards and over the front part thereof, from whence it travels to the said opening
through which it passes in order to heat the back surface.
In connection with this arrangement of oven are the necessary openings and
appliances for freeing the same from any collection of soot, dust, etc., as is well
understood.

Improvements in the Construction of Ovens for Domestic Purposes,
the same being Usually Known as Hot-air Ovens.
We, EDWARD REDMAYNE MORPHET, Ironmonger, and JOHN HARDY, Mason, both
of Settle, Yorkshire 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, that is to say :-
It consists of improvements in the construction of ovens for domestic pur-
poses whereby the hot air or other gases that heat the same are more evenly
distributed over their outer surfaces with the obvious result of raising the temperature
of all the parts thereof in an uniform degree; and in order that this invention may be
more readily understood we hereunto append a sheet of drawings illustrative thereof
to which reference is made, by letters and figures, in the following description.
Fig. 1 is a front sectional elevation of an oven with a suitable portion of its
surroundings, fig. 2 is a side view of fig. 1 as seen in the direction indicated by
arrow A, the plate B (fig. 1) being omitted so as to shew parts behind, and fig. 3 is
plan of fig. I the top plate C being omitted to shew the parts beneath.
Fig. 4 is a perspective view of the oven shewing portions of the plates B and C as
cut away to illustrate parts that would otherwise have been hid.
"
The object above set forth is attained by constructing and so placing the oven a
that when it is required to be heated; by a valve or ་་ damper C being removed so as
to open the vent or flue, the heated air or other gases from the fire pass under the
bottom d, up the side e, over the top f, down the other side g, out of an opening bat
the bottom back corner thereof, around to and up out at the back h of the said oven a
somewhat following the course indicated by the arrows i.
This is accomplished by placing the oven a on its usual brick work supports k so as
to leave its bottom outer surface d (fig. 1) open to the action of the heated air or
gases. Again the flue is made so that the whole surface of the side e is also open
to the action of the heated air, so also is the top and the other side g, however by a
suitable partition or stop piece, usually styled a "midfeather" 1, being placed about
midway between the sides e and g and extending from the back edge of the oven a to
about its centre part, the current of heated air or gases instead of going in the shortest
direction to the opening b is turned aside and brought to pass more towards and over
the front part of the said oven a, somewhat as indicated by arrows i fig. 3, from whence
it travels to the said opening 6 through which it passes in order to heat the back
surface h.
It will readily be understood that the flues arranged at e and has above described
may be constructed either of metal (and so be attached to the oven as is illustrated) or
of brick or other work (in this manner allowing the other parts of the oven to be
detachable) as may be desired.

page_text: In connection with this arrangement of oven are the necessary openings as shewn
at m and n (fig. 4) together with the appliances o (fig. 4) for freeing same from any
collection of soot, dust etc., as is well understood.
Should it be desired to have the part o that partly encircles the oven a in one piece
as illustrated by fig. 4 the bottom portion of the midfeather / may be cut as illustrated
by fig. 4, and by dotted lines fig. 2.
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. The construction and arrangement of parts forming, and in connection with an
oven enabling same to be heated by one current of heated air or gases in the manner
and for the purposes substantially as herein described and illustrated.
2. An oven surrounded by a flue having an opening 6 formed in the position
substantially as herein described and illustrated.
3. The plate B having the opening m, in combination with the oven a having a
flue d, e, f, g, h, substantially as and for the purposes herein described and illustrated.
4. The opening b in combination with the midfeather and the oven a having a
flue d, e, f, g, h substantially as and for the purposes herein described.
