Year: 1861

page_text: LETTERS PATENT to Charles Carey, of Kennington Green, in the County
of Surrey, for the Invention of "IMPROVEMENTS IN THE APPARATUS USED
IN MAKING INFUSIONS OF COFFEE AND OTHER SUBSTANCES."
Sealed the 16th October 1861, and dated the 22nd April 1861.
PROVISIONAL SPECIFICATION left by the said Charles Carey at the
Office of the Commissioners of Patents, with his Petition, on the 22nd
April 1861.
I, CHARLES CAREY, of Kennington Green, in the County of Surrey, do
hereby declare the nature of the Invention for "IMPROVEMENTS IN THE APPA-
RATUS USED IN MAKING INFUSIONS OF COFFEE AND OTHER SUBSTANCES," to be as
follows:-
This Invention has for its object improvements in the apparatus used in
making infusions of coffee and other substances, and consists in improvements
on the apparatus described in the Specification of a former Patent granted
to me, and dated the 17th July 1856, No 1687. The apparatus therein
described consists of a porcelain or earthenware pot, by preference of a cylin-
drical form, and fitted with a suitable cover. This pot receives into it a
wire frame fitting it loosely, and a bag of filtering material is drawn over the
frame.
My present improvements consist in constructing the wire frame in the
following manner:-It is formed of two wire rings, somewhat smaller than
the interior diameter of the pot, connected together; parallel the one to the

page_text: other, by two upright wires about equal in length to the depth of the pot;
to the upper ring of this frame a handle of a semicircular form is jointed,
which when out of use turns down so as to lay close against the upper ring
of the wire frame allowing the lid of the pot to be put into its place.
My Invention also consists in forming two or other number of studs on
the upper ring of the wire frame, and in making corresponding metal eyelet
holes in the filtering bag so that the bag may be readily secured to the frame
and removed therefrom as may be desired. The filtering bag which fits on
to the wire frame I make of Saxony flannel:
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Charles Carry in the Great Seal Patent Office on the 22nd
October 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHARLES
CAREY, of Kennington Green, in the County of Surrey, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by, Her Letters
Patent, bearing date the Twenty-second day of April, in the year of our Lord
One thousand eight hundred and sixty-one, in the twenty-fourth year of Her
reign, did, for Ierself, Her heirs and successors, give and grant unto me,
the said Charles Carey, Her special licence that I, the said Charles Carey,
my executors, administrators, and assigns, or such others as I, the said
Charles Carey, my executors, administrators, and assigns, should at any
timo 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 THE
APPARATUS USED IN MAKING INFUSIONS OF COFFEE AND OTHER SUBSTANCES," upon
the condition (amongst others) that I, the said Charles Carey, 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 Charles Carey, 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:-

page_text: This Invention has for its object improvements in the apparatus used in
making infusions of coffee and other substances. For this purpose I employ
the apparatus shown in the Drawings hereunto annexed.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is an external view, and Figure 2 a vertical section of the appara-
tus; a is an earthenware pot with a cover b; within the pot is the wire frame
c, of which a perspective view is shewn separately at Figure 3. The wire
frame is employed merely to hold up and keep open the bag or filter d shown
separately at Figure 4, and which is made of a close cotton fabric.
In using the apparatus the coffee or other substance to be infused is
placed in the bag d; after affusion of the hot water upon the ground coffee
it should be well stirred in, and the pot covered with its lid for five minutes
or so many more as may be desired. The frame should be placed in the
bag so that the upright wires c, c' should remain equidistant between its
two projecting appendages d', d' and the bag and frame should be so put
into the pot that one of the uprights faces the middle of the spout, the other
resting against its handle. Thus when the bag is drawn out of the pot it
may be placed securely in a slanting position, as is shown by the red lines
in Figure 2, while the last drops of the filtered liquid are leaving the bag.
In witness whereof, I, the said Charles Carey, have hereunto set iny
hand and seal, this Twenty-second day of October, in the year of
our Lord One thousand eight hundred and sixty-one.
CHAS. CAREY. (L.S.)
