Improvements in Coffee Pots.
I, DUVAL POPE GOLDSMITH, of Warrenton, in the County of Fauquier, State
of Virginia, United States of America, do hereby declare the nature of this
invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
-
This invention relates to that class of coffee pots which are constructed with
a view of making drip coffee, and consists in the peculiar and advantageous con-
struction hereinafter described and particularly pointed out in the claims
appended.
In the accompanying drawings:
Fig. 1 is a diametrical section of a coffee pot provided with the improvements.
Fig. 2 is a perspective view of the improved apparatus removed from the
body of the pot.
Fig. 3 is a transverse section taken on the line 3-3 of Fig. 1.
In the said drawings, similar letters designate corresponding parts in all of
the views, referring to which:
A is the body of the pot which is provided with a spout a and handle 6 and
is otherwise of the ordinary construction, and B is the improved apparatus which
is placed in but not fastened to the body A, and is therefore adapted to be
readily removed to permit of it as well as the said body A being thoroughly
cleansed when necessary. The said apparatus A is made up of a base C which
is provided with a depending marginal flange e and a central opening d and is
of a diameter to snugly occupy the body A, a foraminated coffee receptacle or
percolator D which is disposed above the base C and is provided at its upper edge
with an annular, imperforate rim E designed to bear upon the body A and having
a depending flange adapted to rest within the said body, and one or more
(preferably two opposite) upright tubes G which are interposed between the base C
and receptacle D, and serve to support the said receptacle and also to convey
hot water and steam to the same. At its under side the base C is provided with
two U-shaped flanges (" which are of a depth corresponding to that of the
flange c and are designed to facilitate the passage of water from the centre of the
space below the base to the lower ends of the tubes G.
Above the opening d of the base C is disposed a deflector H which has for its
purpose to retard the upward passage of steam and hot water through the said
opening and thereby insure the passage of such steam and water up the tubes G
and into the receptacle or percolator I). The said deflector H is formed of a
piece of sheet metal of a size to entirely cover the opening d, and is of the shape
shown, that is to say, is raised at its centre as indicated by e, inclined down-
wardly toward its margin, and provided with radial corrugations f. The con-
cave corrugations are connected at the edge of the deflector by solder or other
suitable means to the base (', while the convex corrugations form horizontally
disposed passages g, the purpose of which is to permit water to pass to and
through the opening d into the space below the base (.
As will be readily appreciated the deflector H, when covered with water, will
prevent the upward passage of steam and hot water through opening d for the
purpose before stated, and yet will permit of free pasage of water from the space

page_text: above the space below the base C. It will also be observed that the deflector H
as compared with an upwardly seating valve is very cheap and simple and is
advantageous because it is not liable to be rendered inoperative by sediment.
When desired, however, an upwardly seating valve, arranged to control the
opening, may be employed in lieu of the deflector H without departing from
the scope of the invention.
When the improved apparatus B is placed in the body or pot proper A, after
the manner shown in Fig. 1, the rim E on the receptacle D partially closes the
pot, and all that is necessary to complete the closure is a small top I which is
adapted to seat in and on the rim as shown. On the other hand, when the
apparatus B is removed from the body or pot proper A, said body or pot proper
is left entirely empty and free from obstruction and may therefore be quickly
and thoroughly cleansed as may also the apparatus.
In using the improvements, ground coffee is placed in the receptacle D, and
boiling water is poured over the same after which the top I is placed on the
rim E. The water poured on the coffee in receptacle I will percolate through
the coffee and find its way through the passages and opening into the space
below the base C, and when the pot is placed on a stove will be forced up the
tubes G and again caused to percolate through the coffee in receptacle D. This
circulation of the hot water and such steam as may be generated will be main-
tained so long as the pot remains on the stove, and the result will be a strong
coffee of fine flavor.
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-In a coffee pot, the combination with a body or pot-proper; of the apparatus
arranged therein and comprising a base having a depending marginal flange, a
vertically disposed opening and a depending U-shaped flange C₁, a foraminated
coffee receptacle, a tube effecting communication between the space below the
base and the interior of the coffee receptacle and having its lower end opening
into the space within the flange (", and the deflector plate arranged over the
opening in the base; the said deflector plate being raised at its centre and
having the concave corrugations connected to the base, and the convex corruga-
tions forming passages g, substantially as specified.
2. In a coffee pot, the combination with the pot or body A; of the apparatus B
adapted to be removed from the body and comprising the base (having the
marginal flange depending therefrom and a central vertical opening, the forami-
nated coffee receptacle 1 having the imperforate, annular rim E to rest on the
upper edge of the body and also having the depending flange as shown, the
upright fubes connecting the base with the coffee receptacle, and the cover I
bearing on the rim E and closing the top of the coffee receptacle, said cover
combined with the imperforate rim E of the apparatus B serving to close the
top of the pot or body A, substantially as specified.
In a coffee pot, the combination with a body or pot proper; of the apparatus
arranged therein and comprising a base having a depending marginal flange and
a depending U-shaped flange C¹, a foraminated coffee receptacle, a tube leading
from the space below the base and connecting with the interior of the coffee
receptacle and having its lower end opening into the space within said flange C',
substantially as specified.
