Year: 1850

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
HENRY RITCHIE, of Kennington, in the County of Surrey, Gentleman, send
greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Royal Letters Patent under the Great Seal of the United Kingdom of Great
Britain and Ireland, bearing date at Westminster, the Thirtieth day of
November, One thousand eight hundred and fifty, in the fourteenth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said William Henry Ritchie, my exors, admors, and assigns, Her especial
licence, full power, sole privilege and authority, that I, the said William Henry
Ritchie, my exors, adiñors, and assigns, or such others as I, the said William
Henry Ritchie, my exors, adññors, 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, the Invention
of "IMPROVEMENTS IN STOVES," communicated to me from abroad; in which
said Letters Patent is contained a proviso that I, the said William Henry
Ritchie, shall cause a particular description of the nature of the said Invention,
and in what manner the same is to be performed, by an instrument in writing
under my hand and seal, to be inrolled in Her Majesty's High Court of
Chancery within six calendar months next and immediately after the date of
the said in part recited Letters Patent, as in and by the same, reference being
thereunto had, will more fully and at large appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
William Henry Ritchie, do hereby declare the nature of the Invention
communicated to me, and the manner of performing the same, are fully
described and ascertained in and by the following description, reference being
had to the Drawing, and to the figures and letters marked thereon; that is to
say:
The Invention relates to that description of stoves which are known as close
stoves, and which it has long been, desirable to construct capable of being
readily removed from place to place, and be placed upon floors or carpets in
rooms without danger.
DESCRIPTION OF THE DRAWING.
A is the external part of the stove; and B the annular space for the circu-
lation of the air of the apartment. The heated air and products of combustion
from the fire are enclosed by the radiator D, which is suspended from the sand
trough I, as shewn. The products of combustion coming from the fire pass
through openings E into the passage E*, and from thence into the external
circumference C* of the pan C, so as to be again introduced into the fire-place
through the three rows of small holes formed in the fuel pan. The air used in
obtaining combustion in passing through the fire becomes deprived of its
oxygen; and the means employed by me for restoring the same is by the intro-
duction of atmospheric air through the small holes F, otherwise these products
alone coming again into the fire would quickly put it out. The air is admitted
through these small holes to prevent its rushing in too large quantities at a
time. The quantity of air thus admitted is regulated by the small sliding door
H; G is the ash pan, which may be introduced and removed through the
door G*. The fuel which is preferred to be used is carbonized peat, reduced
to powder, or a mixture of peat and charcoal; but any fuel may be used, as the
draft is well regulated. Below the ash pit is arranged a frame K, with blades
K', and by means of two handles, placed one on each side, these blades may
be raised so as to act upon the cinders. Before doing so the door should be
closed, so as to prevent the dust from coming out; these stoves have this advan-
tage, that they may be placed upon the floor, or even upon carpets, because the
sole of it is at all times cold in consequence of the cold air entering the stove
at the lower part. The trough I is filled with sand, so as to prevent any escape
of the products of combustion. J are the openings through which the external
air enters into the stove. When it is desired to use the stove in chambers
where a chimney may be employed whilst the fire is being lighted in the stove,
a piece of pipe or tube may be attached to the stove, as shewn by the dotted
