IMPROVEMENTS IN STOVES AND RANGES
Year: 1861

page_text: LETTERS PATENT to Nathan Ager, of 77, Upper Ebury Street, Pimlico,
in the County of Middlesex, for the Invention of "IMPROVEMENTS IN
STOVES AND RANGES."
Sealed the 9th July 1861, and dated the 11th January 1861.
PROVISIONAL SPECIFICATION left by the said Nathan Ager at the
Office of the Commissioners of Patents, with his Petition, on the 11th
January 1861.
I, NATHAN AGER, of 77, Upper Ebury Street, Pimlico, in the County of
Middlesex, do hereby declare the nature of the Invention for "IMPROVEMENTS
IN STOVES AND RANGES," to be as follows:-
This Invention has for its object improvements in stoves and ranges. For
these purposes, in constructing stoves and ranges, in place of the lower part of
the chimney or flue at the back of a stove or range receiving the products of
combustion from above the fuel in the basket which contains the fire, the
lower part
of the chimney or flue is caused to descend behind the back of the
basket, and to the bottom thereof. The back of the basket is made with bars
or otherwise, with passages through it so that the draft may pass from front
to back of the fire in the basket, the products of the fuel passing through the
back of the basket into the flue or chimney. It is preferred that the sides or
cheeks of the basket should be hollow and form hot air chambers communi-

page_text: cating with the lower part of the flue. The back of the stove or range above
the basket is closed or only has a comparatively small opening above the
back into the flue. The ordinary register of a stove is kept closed, and is only
required to be opened when sweeping the chimney. In order to regulate the
quantity of opening above the back of the basket a slide is used, which may
be raised or lowered so as to enlarge or close the opening into the flue or
chimney above the back of the basket.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Nathan Ager in the Great Seal Patent Office on the
11th July 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, NATHAN
AGER, of 77, Upper Ebury Street, Pimlico, in the County of Middlesex, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eleventh day of January, in the year of our Lord
One thousand eight hundred and sixty-one, in the twenty-fourth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Nathan Ager, Her special licence that I, the said Nathan
Ager, my executors, administrators, and assigns, or such others as I,
the said Nathan Ager, 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 STOVES AND RANGES," upon the condition (amongst others)
that I, the said Nathan Ager, my executors or administrators, by an instru-
ment 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 Nathan Ager, 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 fol-
lowing statement thereof, that is to say :-
This Invention has for its object improvements in stoves and ranges. For

page_text: these purposes, in constructing stoves and ranges, in place of the lower part of
the chimney or flue at the back of a stove or range receiving the products of
combustion from above the fuel in the basket which contains the fire, the
lower part of the chimney or flue is caused to descend behind the back of the
basket and to the bottom thereof. The back of the basket is made with bars
or otherwise, with passages through it so that the draft may pass from front
to back of the fire in the basket, the products of the fuel passing through the
back of the basket into the flue or chimney. It is preferred that the sides or
cheeks of the basket should be hollow and form hot air chambers communi-
cating with the lower part of the flue. The back of the stove or range above
the basket is closed, or only has a comparatively small opening above the back
into the flue. The ordinary register of a stove is kept closed and is only
required to be opened when sweeping the chimney. In order to regulate the
quantity of opening above the back of the basket a slide is used, which may
be raised or lowered so as to enlarge or close the opening into the flue or
chimney above the back of the basket.
And in order that my said Invention may be most fully understood and
readily carried into effect, I will proceed to describe the Drawings hereunto
annexed.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a front view of a stove constructed according to my Invention ;
Figure 2 is a vertical section of the same taken at the line 1, 1, Figure 1; and
Figure 3 is a horizontal section of the same taken at the line 2, 2, Figure 1.
a is the fire basket; b is the lower part of the chimney, which, as will be seen,
descends down behind the basket, and to the bottom of it; c is the back of
the basket consisting of a grating or bars, or it is otherwise formed with holes
through it by which the draft passes from the fire basket to the lower part of
the chimney or flue behind the fire basket. The part of the chimney or flue
above the fire basket is closed by a slide d, at the lower part of which a small
passage may be left, as is shewn at d¹. This slide d is fitted into grooves or
guides at the two sides, and it is capable of being moved by a lever e, which
turns on a centre at e¹; this lever is at one end loosely connected by a fork
embracing a pin or otherwise with the slide d, and at the other end with a
bandle f, by which the apparatus is worked. 9, 9, are air chambers formed
behind the cheeks of the basket; there are openings into these chambers at
g', g', and when the stove is in use, air enters by these openings into the
chambers, there becomes heated, and passes out by the passages g², g², into
the chimney or flue, and in this manner a good draft is ensured, the

page_text: tendency of the heated air so supplied to the bottom of the chimney or flue to
ascend being sufficient in almost any case to prevent a downward current.
h is a register door which is opened for sweeping the chimney. Ranges may
be constructed in a similar manner.
In witness whereof, I, the said Nathan Ager, have hereunto set my
hand and seal, this Eleventh day of July, in the year of our Lord One
thousand eight hundred and sixty-one.
NATHAN AGER. (L.S.)
