IMPROVEMENTS IN KITCHENERS OR COOKING RANGES
Year: 1861

page_text: LETTERS PATENT to William Bell, of the Firm of Sidney, Flavel, and
Company, of Leamington, in the County of Warwick, Manufacturers,
for the Invention of "IMPROVEMENTS IN KITCHENERS OR COOKING
RANGES."
Sealed. the 14th February 1862, and dated the 13th December 1861.
PROVISIONAL SPECIFICATION left by the said William Bell at the
Office of the Commissioners of Patents, with his Petition,' on the
13th December 1861.
I, WILLIAM BELL, of the Firm of Sidney, Flavel, and Company, of
Leamington, in the County of Warwick, Manufacturers, do hereby declare
the nature of the said Invention for "IMPROVEMENTS IN KITCHENERS OR COOKING
RANGES," to be as follows:-
My Invention consists, firstly, of the following improvements in the grates
of kitcheners or cooking ranges. Instead of making the bottom grate in one
piece, and building.or.fixing it in its place with brickwork, I make the said
bottom grate of two parts, namely, of a frame, which is built into the brick-
work, and a-perforated-plate-or-set-of-grate-bars,-which-is dropped-into-the-
said frame. The said perforated plate or set of grate bars can be removed and
replaced at pleasure: When a false or contracting grate bottom on legs is
placed in the grate, the moveable set of grate bars may be taken out. The
said false grate bottom-rests upon the fixed frame, and the ashes falling:

page_text: through the said false grate bottom pass freely through the opening in the
said fixed frame, giving a free draught, and preventing the burning of the
false bottom. I make a projection at the back of the false grate bottom to fit
against the inclined back of the fireplace, to prevent the fire falling through
into the ash-pan.
My Invention consists, secondly, of an improved ventilator for the ovens.of
kitcheners or cooking ranges. The said ventilator consists of a strong cast-
iron box at the back of the oven, the said box. extending over nearly the whole
width of the oven. The said box opens through its whole length into the arch
of the oven, and serves to remove rapidly the steam arising from the meat or
other articles being cooked. The said cast-iron box also forms the back
stopping in front of the flue under the hot plate in place of the bricks usually
employed, which said bricks frequently give way and render the heating of the
oven imperfect.
My Invention consists, thirdly, of an improved latch for the oven doors of
kitcheners or cooking ranges. The said latch consists of two levers, namely, a
long lever, constituting the true latch, and turning on a joint at a distance
from its middle, and a shorter lever with rule joint for acting on the said latch.
The latch is situated in a plane parallel to the door, while the short lever is
situated in a plane at right angles thereto. One end of the short lever is
inserted in one end of the latch, and by lifting the projecting end of the said
short lever the distant end of the latch which engages with the catch on the
side of the oven is raised. The weight of the parts restores them to their.
normal position, but a spring may be employed more effectually to secure
this. The parts of the catch are enclosed in a case fixed to the oven
door

BELL, of the Firm of Sidney, Flavel, and Company, of Leamington, in the
County of Warwick, Manufacturers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirteenth day of December, in the year of our
Lord One thousand eight hundred and sixty-one, in the twenty-fifth year of 35
Her reign, did, for Herself, Her heirs and successors, give and grant unto

page_text: me, the said William. Bell, Her special licence that I, the said William'
Bell, my executors, administrators, and assigns, or such others as I, the said
William Bell, my executors, administrators, and assigns, should at any time
agree with, and no others, from time to time and at all times thereafter during.
the term therein expressed, should and lawfully might make, use, exercise, and.
vend, within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN KITCHENERS OR*
COOKING RANGES," upon the condition (amongst others) that I, the said William
Bell, my executors or administrators, by an instrument in writing under my, or
their, or one of their hands and seals, should particularly describe and ascertain
the nature of the said Invention, and' in what manner the same was to be
performed, and cause the same to be filed in the Great Seal Patent Office
within six calendar months next and immediately after the date of the said
Letters Patent.
.
NOW KNOW YE, that I, the said William Bell, do hereby declare
the nature of the said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement thereof, that is to say -
My Invention consists, firstly, of the improvements in the grates of
kitcheners or cooking ranges herein-after described, and illustrated in Figures 1
to 15, both inclusive, of the accompanying Drawings. Instead of making the
bottom grate of kitcheners or cooking ranges of one piece, and building or
fixing it in its place with brickwork, I make the said bottom grate of two
parts, namely, of a frame which is built into the brickwork, and of a move-
able perforated plate or set of grate bars, which is dropped into the said
frame.
Figure 1 represents in plan the said frame, which is built into the brick-
work; Figure 2 is a front elevation of the same; Figure 3 is a longitudinal
vertical section of the same; Figure 4 represents a section taken across the
middle of the plan, Figure 1; Figure 5 represents in plan and end elevation
the moveable perforated plate or set of grate bars, and Figure 6. represents
the same in longitudinal section; Figure 7. represents in plan the perforated
plate or set of grate bars dropped into its place in the fixed frame; and
Figure 8 is a cross section taken through the middle of Figure 7. The
fixed frame of the grate is marked a, and the perforated plate or set of
bars is marked b, in the several Figures.
grate
When a false or contracting grate bottom on legs is placed in the kitchener
or cooking range provided with a grate made as described and illustrated..in
Figures 1 to 8, both inclusive, of the Drawings, the perforated or moveable set

page_text: of grate bars b may
be taken out of the fixed frame a, and the false or con-
tracting grate bottom made to rest upon the said fixed frame a.
Figure 9 represents in front elevation a false or contracting grate bottom;
and Figure 10 represents the same in end elevation; Figure 11 represents,
a longitudinal vertical section; Figure. 12 a transverse vertical section;
Figure 13 is a plan, and. Figure 14 is a plan of the false or contracting
grate bottom in its place on the fixed frame a; Figure 15 is a, trans-
verse vertical section of the fireplace of the kitchener or cooking range,"
shewing the fixed frame a with the false or contracting grate bottom
standing upon it. The false or contracting grate bottom is marked c. in the
several Figures. By making the said false or contracting, grate bottom c.
rest directly upon the fixed frame a, the grate bottom 6 having been removed,
from the frame a, the ashes falling through the said false or contracting igrate
bottom c pass freely through the opening in the said fixed frame a, thereby
giving a free draught, and preventing the burning of the false grate bottom c.
I make a projection d at the back of the false grate bottom c, the said projec-
tion d having an inclined edge. The sad projection d'fits against. the inclined
back e of the fireplace f (see Figure.15), and prevents the fire from falling at
the back of the false grate, bottom into the ash-pit or pan.
My Invention consists, secondly, of an improved ventilator for the ovens of
kitcheners or cooking ranges. This part of my Invention is illustrated in
Figures 16 to 22, both inclusive, of the accompanying Drawings.
"
Figure 17 represents a plan of the top of the oven of a kitchener or cooking
range having one of my improved ventilators applied thereto, and Figure 20
is the same with the ventilator shewn in-horizontal section; Figure 16 is a
vertical section taken through the line h, Figure 17, and Figure 18 is a
vertical section taken through the line i, Figure 17; Figure 19 is a section
taken through the, line k, Figure 17. The said ventilator consists of a strong
cast-iron box marked gin the several Figures. in which it is represented, and
is also shewn separately in front elevation in Figure 21, and end elevation in
Figure 22. The said box or ventilator g is situated at the back of the oven,
and, extends over the whole, or nearly the whole width of the top of the said
oven. The said ventilator 9 communicates with, the, oven. by a series of open-
ings made in the top of the oven; or one opening of nearly the same size
-as-the-ventilator-g-may-be-made-in-that part of the oven over which the said
ventilator is situated. The end g of the, box, or, ventilator g' communicates
with the flue m, which passes down one side, and under the bottom of the
oven in the usual manner, and: communicates: with the chimney; n is a
damper, which may be made, to slide by the rod and handle o. When the rod

page_text: and handle o are pushed in, the damper n cuts off the communication be-
tween the ventilator 9 and the flue m, and when the rod and handle o are
-pulled out the damper n is withdrawn, and free communication is opened
between the ventilator g and flue m. When the rod and handle o are pulled
out the steam and vapour arising from the meat or other matter being cooked
are rapidly removed from the oven. The ventilator or cast-iron box g also
forms, the back stopping in front of the flue under the hot plate in place of
the bricks usually employed, which said bricks frequently give way, and render
the heating of the oven imperfect.

My Invention consists; thirdly, of an improved látch for the oven doors of
kitcheners or cooking ranges. This part of my Invention is illustrated in
Figures 23 and 24 of the accompanying Drawings; Figure 23 representing
the said latch in elevation partly in section); the said elevation Figure 23.
being of the inside of the latch, that is, the side which is turned towards the
oven door of the kitchener or cooking range. Figure 24 is a transverse vertical
section of the latch taken through the line p, Figure 23. q is a case or,cover-
ing in which the principal parts of the latch are contained, which said. case is
affixed to the oven door. The said latch, consists principally of two levers,
r, t, the longer lever 1, which constitutes the true latch, turns upon the centre
s, and the shorter levert turns upon the rule joint at u. The said lever t is
situated at right angles to the latch r, the end t² of the lever t engaging in a
hole in the end of the latch r. By lifting the handle end t³ of the, levert,
the end of the latch r is depressed, and the end of the said, latch r is
raised and disengaged from the catch or staple v.. which said staple is fixed
on the side of the oven. The weight of the levers r and t restores them to
their normal position, but a spring w may be employed for the purpose of
more effectually securing the descent of the end of the lever or latch r. All
the parts of the latch are secured to the case q, and the said latch is fixed to
and removed from the door, of the oven by connecting the said case 'q thereto
and disconnecting it therefrom. The case q is fixed to the oven door by the
rivets x, x.
Having now described the nature of my Invention, and the manner in
which the same is to be performed, I wish it to be understood that I do not
limit myself to the precise details herein described and represented in the
5 accompanying Drawings, as the same may be varied without departing from
the nature of my Invention; but I claim as my Invention.
Firstly, the improvement in the grates of kitcheners or cooking ranges
-berein-before described, and illustrated in Figures 1 to 8, both inclusive, of the
accompanying Drawings, that is to say; making the bottom grate in two parts,

page_text: namely, of a frame to be built into. the brickwork, and a perforated plate or
set of grate bars to be dropped or placed in the said fixed frame.
Secondly, the improvement in the grates of kitcheners or cooking ranges
herein-before described and illustrated in Figures 9 to 15, both inclusive, of the
accompanying Drawings, that is to say, making the false or contracting grate
bottom with a projection at its back so as to make it fit against the inclined
back of the fireplace, and prevent the fire falling at the back of the said false
or contracting grate bottom into the ash-pit or pan of the grate.
Thirdly, the new or improved ventilator for the ovens of kitcheners or
cooking ranges herein-before described, and illustrated in Figures 16 to 22,
both inclusive, of the accompanying Drawings, that is to say, a ventilator con-
sisting of an iron box situated at the back and on the top of the oven, the
said box extending the whole or nearly the whole width of the oven, and com-
municating therewith by means of a series of openings or one large opening.
Lastly, the new or improved latch for the oven doors of kitcheners or cooking
ranges, constructed essentially in the manner herein-before described, and
illustrated in Figures 23 and 24 of the accompanying Drawings.
'In witness whereof, I, the said William Bell, have hereunto set my"
hand and seal, this Twenty-third day of May, in the year of our
Lord One thousand eight hundred and sixty-two.
