Specification Accepted, 29th Nov., 1887
I, JOSIAH SPURGEON STRINGER, of Columbia, in the County of Henry, State of
Alabama, and United States of America, Gentleman, do hereby declare the nature of
my invention for "IMPROVEMENTS IN COFFEE-POTS," and in what manner the same is
to be performed, to be particularly described and ascertained in and by the following
statement:-
The object of my invention is to provide a new and improved coffee-pot which is
simple in construction, produces good coffee rapidly, and extracts all the aromatic and
flavoring elements from the ground berries.
The invention consists in the combination with a pot, of devices for passing cold
water gradually into the pot to meet and condense the aromatic vapors; in providing
the lid and other openings with devices whereby they may be hermetically sealed, as
will be described; in providing the pot with a filtering bag for holding the ground
coffee, from which the liquid decoction may readily be caused to pass into the body of
the pot and from which the grounds may easily be removed; and in certain arrange-
ments and combinations of parts as will be hereinafter fully set forth, reference being
had to the accompanying drawing forming a part of this specification and which shows
a longitudinal sectional elevation of my improved coffee-pot.
The pot A has a handle B, and a spout C, the lower end of the spout being near the
bottom of the pot. An annular groove D¹ is made around the pot at the top to contain
water for sealing the lid E and preventing any escape of steam. A filtering bag F,
made of muslin or any other suitable material is secured at the top of the pot,
preferably by a ring G, fitting within the band D and having a ledge G', adapted to
rest on the upper edgo of the band D, and thus hold the filtering bag in the pot. A
button H projects from the inner surface of the ring G which button serves as a handle
for the ring. A string I is secured to the bottom of the bag and may be provided at
its upper end with a loop to pass over the button H. A ring J rests in the bottom
part of the bag to keep it distended. On the top of the lid E a cup L, having an open
top, is formed and in the lid E an opening M is formed which is covered by a few
layers N of fabric, or by a sponge, or by a plate or plates of perforated metal.
cup O which is slightly tapered or provided with an extension bead fits within the top
of the cup L and is provided with a lid P. A transverse plate or ledge Q is secured
in the cup O near the top.
A

page_text: A small aperture R is made in the bottom of the cup O and may be closed by a
plug R or other device or may be left open. Other equivalents of these devices,
namely, of the parts L, N, O, may however be used to pass cold water gradually into
the pot to condense the vapors.
A tapering tube S projects downward from the lid E toward the middle of the pot
and on its lower end a water seal is formed, by a cup T, which is adapted to contain
water and prevent the steam from rising up through the tube S, or by other equivalent
means.
•
The pot is used in the following manner: The ground coffee is placed in the bag F
and then water, preferably cold, is poured into the groove D¹, the lid E is placed on
the pot, the cup O is filled with cold water and then hot. water is poured through the
tube S into the sack or bag F. The opening R in the cup O is preferably left open
so that a continuous stream of cold water can flow upon the cloth N over the opening M
in the cover E, whereby all steam that meets said water or fabric is condensed. When
the pot is tilted to pour out coffee, the ledge Q in the cup O prevents the water in the
cup O from being spilled. The string prevents the bag from passing into and
stuffing the lower end of the spout C, and by means of the string the bag can easily
be inverted to cause the fluid in immediate contact with the coffee to pass through the
bag, and also for the purpose of removing the grounds. The pot can be used for
preparing tea as well as coffee. In place of the string I, a spring, chain, etc. may
be used.
Having now particularly described and ascertained the nature of my said invention,
and in what manner the same is to be performed, I declare that what I claim is :-
1. The combination with the pot having an opening communicating with its interior,
of devices for passing cold water gradually through said opening, substantially as set
forth.
2. The combination with the pot, of the cover having an aperture, a piece of fabric
or similar porous substance placed thereover, and a water reservoir or cup situated
above and adapted to deliver its contents upon said fabric, substantially as herein
shown and described.
3. The combination with a pot, of a filtering bag held therein, and a string or
analagous device extending from the lower part of the bag to the top of the same,
substantially as herein shown and described.
4. The combination with the pot, of a filtering bag, a ring for supporting the same,
and a string or analogous device secured to the bottom of the bag and to said ring,
substantially as herein shown and described.
5. The combination with the pot, of a filtering bag held therein, a loose ring in the
lower part of said hag, and a string, substantially as herein shown and described.
6. The combination with the pot and cover, of a groove for sealing the cover, a tube
for pouring water into the pot, and a device for forming a water seal at the lower end
of said tube, substantially as herein shown and described.
Dated this 12th day of January 1887.
