PHILIP A. COVINGTON, OF FORT WORTH, TEXAS, ASSIGNOR OF ONE-HALF
TO ALBERT H. IVERSON, OF SAME PLACE.
COFFEE-POT.
SPECIFICATION forming part of Letters Patent No. 333,282, dated December 29, 1885.
Application filed June 30, 1885. Serial No. 170,284. (No model.)To all whom it may concern:
Be it known that I, PHILIP A. COVINGTON,
a citizen of the United States, residing at Fort
Worth, in the county of Tarrant and State of
5 Texas, have invented certain new and useful
Improvements in Coffee-Pots; and I do here-
by declare that the following is a full, clear,
and exact description of the same, reference
being had to the annexed drawing, making a
Io part of this specification, and to theletters and
figures of reference marked thereon.
The present invention has relation to that
class of coffee-pots in which the body of the
pot contains a cone-shaped chamber provided
15 at the apex with a tube for the discharge of the
boiling water as it passes through the same
into a receptacle containingthe coffee; and the
object thereof is to improve the construction
of this class of coffee-pots,which will be here-
o20 inafter described,and pointed out in the claims.
In the accompanying drawing,which repre-
sents a sectional elevation of my invention, A
represents the body of the coffee-pot,provided.
with the usualspout, a, and handle b. On the
25 bottom of the body A rests a conical chamber,
B, of a diameter nearly equal to the interior
diameter of the body, and has one or more
perforations, c, for the boiling water to enter.
The apex or smaller end of the conical cham-
30 ber B has an upright tube, d, and to this tubeis
connected the cup C, for containing the ground
coffee. This cup C is slightly tapering and
has a wire-gauze or perforated bottom, e, and
a circumferential shoulder or bead, f, which
35 rests upon the upper rim of the body A to
support the cup therein. Above the shoulder
or bead f is an extension, D, for supporting
and containing a condensing-vessel, E, having
a convex bottom, g, to present an increased
40 condensing-surface to steam, the vessel con-
taining cold water. Over the upper end of
the tube d fits a sleeve, h,which is attached to
a concavo-convex perforated retaining-plate F,
to keep the ground coffee from rising overthe
45 tube.
At the point where the bottom of cup C joins
the tube d, I provide a flaring cap, G. to pre-
vent the grounds of the coffee from settling and
caking around the tube; also to conduct the
50 water toward the rim of the cup, when it es-capes through the tube onto the coffee-grounds
and passes down through the same.
After the body A of the coffee-pot has been
partially filled with water, the coffee placed in
the cup C, and the retaining-plate F over the 55
coffee, the vessel E is filled with cold water
and set in position over the extension D of the
cup. As the water boils it will circulate
through the tube d and discharge on the ground
coffee contained in cup C, passing through it 6o
and through the bottom e into the body A of
the pot, where it again passes through the tube
over, onto, and through the coffee in like man-
ner, thus keeping up a continuous circulation
of the boiling water through the finely-ground 65
coffee. The steam which passes upward asit
comes in contact with the bottom g of vessel E
is condensed and drops back upon theground
coffee, there not being a particle of steam es-
caping from the pot, and consequently all of 70
the aroma of the coffee is retained.
The convexity of the bottom g, as we;l as
the flaring cap G, are both valuable in perform-
ing their functions, the convexity of the bot-
tom giving an increased condensing-surface to 75
the steam, and consequently a more rapid and
perfect condensation, and the flaring cap pre-
venting the finely-ground coffee from settling
and caking around the tube, and also guiding
the water outwardly after it has worked 8(,
through the grounds. The extension D to the
cup C is also essential, as it enables the con-
densing-vessel to be supported some distance
above the coffee contained in the cup, thus al-
lowing more space for the steam to circulate 85
and be condensed.
Having now fully described my invention,
what I claim as new, and desire to secure by
Letters Patent, is-
1. A coffee-pot provided with a cone-shaped 90
chamber perforated at its base and at its apex
provide with an upright tube, a cup having
aperforated bottom and surrounding said tube,
and a flaring cap connecting the tube and bot-
tom, as shown, and a convex-concavo perfo- 95
rated retaining- plate having a sleeve to fit
over the end of the tube, substantially as and
for the purpose set forth.
2. A coffee-pot havinga cone-shaped cham-
ber perforated as shown, and provided with oo
