AN IMPROVED COFFEE POT
Year: 1841

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
WARD ANDREWS, of Wolverhampton, in the County of Stafford, Ironmonger,
send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, the Twenty-first day of July, in the fifth year of Her reign, did,
for Herself, Her heirs and successors, give and grant unto me, the said
William Ward Andrews, Her especial licence that I, the said William
Ward Andrews, my exors, admors, and assigns, or such others as I, the said
William Ward Andrews, my exors, admors, 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, and also in all Her said Majesty's Colonies and Plantations abroad,
my Invention of "AN IMPROVED COFFEE POT;" in which said Letters Patent
is contained a proviso obliging me, the said William Ward Andrews, 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

page_text: Figure 2, a plan of the same; and Figure 3 a separate view of the closed and
perforated box; similar letters being used to denote similar parts in all the
Figures. A is the closed and perforated box for holding the coffee to be acted
upon. This box is furnished with a hollow screw tap or collar at B to screw
it firmly to the bottom of the body of the coffee pot. C is the cover fastened
on by a lug and catch at one side, as shewn in Figure 3. D is a perforated
cone rising up in the centre of the box from the hollow screw tap, and round
which the coffee to be acted upon is to be placed. The perforated holes of
this cone, it will be observed, are somewhat larger than those of the box. E is
a water chamber, one end leading under the hollow screw tap B, and thus
communicating with the cone above it, while the other end communicates by
the aperture F to the pump cylinder G, in which the solid piston H works by
means of the piston rod I and the cross head J. The mode of operating with
this coffee pot is as follows:-The solid piston H being drawn up to the top of
the pump cylinder G, and the coffee (previously carefully roasted and ground)
placed in the box A with its cover C fastened down, and the box A screwed
fast to the bottom of the body of the coffee pot, I pour into the pump
cylinder G the required quantity of boiling water through the filling lip K, and
when full I press down the solid piston by means of the cross head J, and thus
force the water through the coffee, and the perforated and closed coffee box A,
into the main body of the coffee pot, while any water that may accidentally get
into the pump cylinder G by this action is easily lifted up by raising the solid

page_text: piston again to the hole or vent L, and thus allowed to escape into the main
body of the coffee pot.
Now whereas it is evident that my said Invention is susceptible of various
modifications in form; for instance, my pump cylinder may be placed over and
communicating directly with the covered coffee box and form one with it, thus
rising through the centre of the main body of the coffee pot instead of at one
side, as shown in the Drawing, or the lower end of the pump cylinder may be
perforated so as itself to form the coffee box, and a cover then fitted to the
bottom instead of the top of the box, or the main body of the coffee pot may
be used as the pump cylinder by having a solid piston large enough in circum-
ference to fit the same, with an escape pipe for the water, when it has been
forced by the solid piston through the coffee box, to rise again, and empty itself
into the body of the coffee pot above the solid piston.
But whereas I claim as my Invention the improved coffee pot aforesaid,
whereby I am enabled to force the hot water of which the coffee is to be
made, by means of a solid piston and force pump, through the coffee while the
said coffee is contained in a fixed, closed, and perforated box, as aforesaid.
And such my Invention being, to the best of my knowledge and belief, entirely
new, and never before used within that part of Her said Majesty's United
Kingdom of Great Britain and Ireland called England, Her said Dominion of
Wales, or Town of Berwick-upon-Tweed, nor in any of Her said Majesty's
Colonies and Plantations abroad, I do hereby declare this to be my Specifica-
tion 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, the said William Ward Andrews hath hereunto
set his hand and seal, this Nineteenth day of January, One thousand
eight hundred and forty-two.
