Improvements in Coffee Pots.
I, ALPHEUS FAY, of 160 West Ninth Street, Cincinnati, in the County of
Hamilton, and State of Ohio, United States of America, Gentleman, 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:
"
My invention relates to that class of coffee pots in which the ground coffee is
held in an elevated position and boiling water.allowed to percolate therethrough
into the pot below, and its object is to provide an improved construction of the same
whereby I secure superior advantages with respect to efficiency in use.
The invention consists in the novel construction and combination of parts
hereinafter fully described and claimed.
In the accompanying drawings:
Figure 1 is a central longitudinal sectional view of a coffee pot constructed in
accordance with my invention.
Figure 2 is a similar view taken at right angle to Fig. 1.
Figure 3 is a plan view of the cup or receptacle for containing the ground coffee.
Figure 4 is a view of the base looking from the underside.
In the said drawing, the reference numeral 1 designates a coffee pot having a
cover 2, a spout 3 provided at its inner end with an oblong plate 4 of perforated
metal, and a handle 5 made of wood or other non-conducting material connected by
metal sockets 6 at each end with curved rods 7 soldered to the pot.
The numeral 8 desiguates a base consisting of an annular rim 9 and a concavo-
convex top 10, and is designed to fit in the pot, the rim 9 resting on the bottom
thereof. The cover 10 is provided with two diametrically opposite, pipes 12
communicating with the space above the cover.
Secured to said cover are four
vertical pipes 13 two at each side, or diametrically opposite each other, the lower
ends of which communicate, with four inwardly extending and downwardly
inclined pipes 14 the ends of which are cut off horizontally so as to present a large
opening at said ends. These pipes are somewhat larger than the pipes 13 with
which they communicate, and they are inclined laterally or sidewise, see Fig. 4 as
well as downwardly so that the openings therein will not be in line with each
other.
Telescoping within the pipes 13 are four pipes 15 which extend up through the
perforated bottom 16 of a ground coffee receptacle 17 provided with an imperforate
rim 18. Connected with these pipes 15 are transverse perforated, pipes, 18ª,
the ends of which are bent downward at right angles and telescope in the upper
ends of said pipes. The numeral 19 designates two transverse perforated partitions
which do not extend quite up to the top of the coffee receptacle and divide the same
into three compartments.
The percolating device comprising the base, the pipes, the coffee receptacle and
connections, is placed in the pot with the rim of the base resting on the bottom
thereof. A sufficient quantity of water is poured into the pot to reach a level just
below the coffee receptacle, the water also filling the space between the cover of the
base and the bottom of the pot through the pipes 12, and rising in the vertical pipes
to the level in the pot. Ground coffee is then put in the middle compartment of
the coffee receptacle and the pot is placed on a stove or other heater, and when the
water has reached the boiling point it will be forced up through the pipes 13 and 15
into the transverse perforated pipes from which it will be sprayed upon the coffee

page_text: and percolating therethrough will escape into the pot beneath in a clear and
clarified condition. A constant circulation will be kept up as long as the water is
kept at the boiling point.
By reason of the peculiar construction of the sidewise and downwardly inclined
pipes 14, better results are attained than if the same were cut off square instead of
obliquely as shown.
The pipes 15 telescoping into the pipes 13 allows the coffee receptacle to be
adjusted vertically to accommodate it to different sized pots. It may also be
adjusted to accommodate it to different quantities of coffee to be made, as it is very
essential that the water level in the pot should be just below the coffee receptacle,
and when the amount of coffee to be made is, for example only one-third the
capacity of the pot, the latter will be only one-third filled and the coffee receptacle
pushed down so that it will nearly reach the water level. By this means the water
will not have to be forced so high, as if the coffee receptacle were stationary or
non-adjustable.
The object of the transverse pipes telescoping in the pipes 15 is that they may be
removed for cleaning purposes, and the object of the perforated partitions is that
when the water is fed too fast to the central compartment containing the coffee it
will overflow into the side compartments and pass therethrough into the pot
without carrying any grounds with it.
When the coffee is ground very fine it should be placed in a bag or sack before
being put in the receptacle but if coarsely ground it can be placed loose therein.
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 percolating device for coffee pots the combination with the base, the
diametrically opposite pipes in the top thereof, the vertical pipes and the enlarged
side-wise and downwardly inclined pipes communicating therewith, and having their
inner ends cut off obliquely, of the pipes telescoping within said vertical pipes, the
coffee receptacle having a perforated bottom through which said pipes pass and the
transverse perforated pipes connected with the upper ends of said pipes, substantially
as described.
2. In a percolating device for coffee pots, the combination with the base, the
diametrically opposite pipes in the top thereof, the diametrically opposite vertical
pipes, and the enlarged sidewise and downwardly inclined pipes communicating
therewith and having their inner ends cut off obliquely, of the pipes telescoping
within said vertical pipes, the coffee receptacle having a perforated bottom through
which said pipes pass, the transverse perforated pipes having their ends bent
at right angles and telescoping in said pipes and the perforated partitions,
substantially as described.
3. In a coffee pot, the combination with the spout of the oblong perforated metal
plate covering the inner end thereof, substantially as described.
4. The combination with a coffee pot, of the non-conducting handle, the metal
sockets at each end and the bent arms secured thereto and to the pot, substantially
as described.
