AN IMPROVEMENT ON OVENS
Year: 1838

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPH
GREEN, of Ranelagh Grove, Chelsea, in the County of Middlesex, Gentleman,
send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Second day of June, in the first year of Her reign, did,
for Herself, Her heirs and successors, give and grant unto me, the said
Joseph Green, Her especial licence, that I, the said Joseph Green, my exors,
admors, and assigns, or such others as I, the said Joseph Green, my exors,
adiñors, or assigns, should at any time agree with, and no others, from time
to time and at all times during the term of years therein expressed, should
and lawfully might make, use, exercise, and vend, within England, Wales, and
the Town of Berwick-upon-Tweed, my Invention of "AN IMPROVEMENT ON
OVENS;" in which said Letters Patent is contained a proviso obliging me, the
said Joseph Green, by an instrument in writing under my hand and seal,
particularly to describe and ascertain the nature of my said Invention, and in
what manner the same is to be performed, and to cause the same to be
enrolled in Her said Majesty's High Court of Chancery within six calendar
months next and immediately after the date of the said recited Letters Patent,
as in and by the samé, reference being thereunto had, will more fully and at
large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Joseph Green, do hereby declare the nature of my said Invention to consist
in rendering the reflected heat of an ordinary Dutch oven, or other oven

page_text: baking; first, by covering the material to be baked, when placed on the shelf
of the oven, with a close cover so fastened to the shelf as always to retain the
same relative position to the top, bottom, and sides of the oven, as is
most conducive to the effect required; and, secondly, by placing a reflector
or curved plate at the bottom of the oven corresponding in curve with its
domed top or nearly so. And in further compliance with the said proviso,
I, the said Joseph Green, do hereby describe the manner in which my said
Invention is to be performed by the following statement thereof, reference
being had to the Drawing annexed, and to the figures and letters marked
thereon (that is to say):-
:-
DESCRIPTION OF THE DRAWING.
Figure 1 represents a side view of one of my improved ovens in section,
showing the relative distance at which the new parts are kept from the back,
top, and bottom of the oven. O, O is an ordinary tin Dutch oven. H is the
handle by which the whole is lifted. S is a moveable shelf of rolled plate
iron resting on two side brackets and one back bracket B, B, B; this shelf
should be one eighth of an inch smaller than the oven, except at the back
where it rests on the bracket, and at the front where it touches at each side.
On the shelf is a cast-iron cover C, which is attached to the shelf at the back
part by a hinge or joint J, as here shown, and should fit down perfectly close
on the shelf. P is supposed to be a pie or pudding undergoing the process of
baking. R is a curved or concave reflecting plate, made, like the oven, of tin,
and corresponding as nearly as may be with the curve of the top of the oven.
This reflecting plate rests against the end of the back bracket, and is kept
from sliding forward by the lip or rim in front of the bottom of the oven.
Figure 2 is a front elevation of Figure 1, and Figure 3 is a separate view of
the shelf and cover removed from the oven, the dotted lines shewing the
position the cover would take when thrown completely back on its hinge.
Figure 4 is a stout holder or instrument made of round iron rod, for removing
the shelf from the oven when hot; and Figure 5 is a diagram showing the
shape of the shelf in plan, and its distance from the sides of the oven.
Now whereas I claim, as my Invention, the projecting iron shelf and cover
united to it by a hinge, in order to preserve it at one settled distance from the
back and sides of the oven, and also the reflecting plate underneath all, as
applied to ordinary Dutch oven, or any other oven on the same principle,
thereby constituting my said improvement on ovens; and such my Invention
being, to the best of my knowledge and belief, entirely new and never before

page_text: used within that part of Her said Majesty's United Kingdom of Great Britain
and Ireland called England, Her Dominion of Wales, or Town of Berwick-
upon-Tweed, I do hereby declare this to be my Specification of the same, and
that I do verily believe this my said Specification doth comply in all respects,
fully and without reserve or disguise, with the proviso in the said herein-before
in part recited Letters Patent contained, wherefore I do hereby claim to
maintain exclusive right and privilege to my said Invention.
In witness whereof, I, the said Joseph Green, have hereunto set my
hand and seal, this First day of December, One thousand eight hundred
