Improvements in and relating to Coffee-pots.
I, MONROE MATTISON, residing at Busti, in the County of Chautauqua and State of
New York, one of the United States of America, Gentleman, do hereby declare the
nature of my said invention and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:-
Referring to the accompanying Drawings-
Figure 1, is a representation of this invention and is a vertical section ;
Figure 2, is a detail and a perspective view, partly broken away on the side.
This invention has relation to coffee-pots; and it consists in the construction and
novel combination of parts, as hereinafter set forth and claimed.
In the accompanying drawings, the letter, A, designates the lower or main vessel,
which is preferably constructed with a copper-armed base, and is provided at its
upper portion with the cylindrical bearing-rim, B, which receives the upper vessel or
steaming-chamber, C, which is provided with a circumscribing bead or bearing, C*,
near its upper edge, designed to engage the upper edge of the cylindrical_bearing-
rim, B, of the main pot to limit the descent of the steam-chamber. The latter
projects above the edge of the rim, B, a short distance, and this exposed portion is
designed to be covered in by the drop cylindrical flange, D, of the top or cover, E, of
the pot which engages the rim, B, on its outer surface and extends down to engage
the stop-bead or bearing, F, on the main pot at the lower portion of said rim, B,
so that when said cover is in position the top of the pot is tightly closed. The spout
is also closed by a thimblo-cover, G.
The steaming cup or vessel, C, is provided with the bent steam-tube, H, and the bent
siphon, K. The steam-tube, H, extends from the central opening, h, in the bottom
of the vessel, C, upward, and then bending over terminates in an open end, ¹, near
the outer wall of the vessel and above its bottom, as shown. The siphon, K, is formed
with a long leg, k, which extends through an aperture, k¹, in the bottom of the
vessel, C, upward therein, and is bent over to form the short leg, k³, which terminates
above and near the bottom of said vessel. The bend, k³, of the siphon stands below
the upper bearing-rim of the pot, and for pots of ordinary size about two inches above
the bottom of the steaming-cup. This steaming cup or vessel is provided with a
transverse bar or handle, CT.
The operation of making coffee in this pot is as follows:-
The coffee is put into the main vessel, A, and hot water is poured upon it. Then
the steaming-cup is placed in position in the upper part of the pot, A, and cold water
to the depth of about one inch is poured therein. The outer or enveloping cover
is then put in place, covering in the steaming-chamber, and, the spout having been
closed, the coffee is put on to boil, the steam and vapor passing up through the
tube, H, into the water in the chamber, C, where it is condensed.
When the coffee has boiled a sufficient time, the chamber, C, is to be filled with
water, bringing its surface-level above the bend of the siphon, and then the
contents of this chamber will pass down into the main vessel. The coffee is then
made.

page_text: Having now particularly described the nature of my said invention, and in
what manner the same is to be performed, I declare that what I claim is-
The coffee-pot comprising the main pot having a suitable distance below its upper
edge a circumscribing bearing or stop-bead, the steaming cup or chamber having a
circumscribing bend or bearing resting upon the upper edge of said main pot, said
steaming cup also having a bent steam-pipe, and a siphon-pipe, the discharge end of
said steam-pipe and the receiving end of said siphon-pipe reaching down within n
short distance of the bottom of said cup, the drop cover having a deep flango, the
lower edge of which rests upon the stop-bead or bearing of the main body, substantially
as set forth.
Dated this own any of May 1890.
