Improvements in Coffee or Tea Pots and Urns.
1, CHARLES HALSTEAD, of Brooklyn, in the County of Kings and State of New
York, United States of America, Manufacturer, do hereby declare the nature of my
invention for IMPROVEMENTS IN COFFEE OR TEA POTS AND URNS to be as
follows:-
.―
Referring to the accompanying drawings,
Figure 1. represents a vertical central section of a coffee-pot embodying my
invention.
Figure 2 represents a perspective view of a coffee-receptacle detached, it being
partly broken away to expose the filter within it.
Figure 3. represents a horizontal section of a modification of my invention.
Figure 4. represents a perspective view of another modification thereof.
Figure 5. is an enlarged detail view showing the spout-connection of the band
and the earthenware vessel.
Similar letters of reference indicate similar parts.
Referring to the drawings, the letter A indicates an earthenware vessel forming
the body of the pot, in which vessel, near the bottom, is a lateral outlet B, provided
with a metallic spout C, of any usual or suitable shape.
For the purpose of connecting the spout C to the vessel A, I employ a metallic
band D, which is fitted snugly on the vessel over said outlet B, it having an
opening D opposite thereto, and to which the spout is soldered or otherwise
attached at a point opposite said opening, as shown.
To the metallic band D is soldered or otherwise attached a metallic lining e
which is fitted in the outlet. B of the earthenware vessel and fastened therein, so
that the band, together with the spout C, is firmly held in position on the vessel by
means of said lining interlocking with the band, forming a strong and durable joint
and one which may be soldered without danger of exposing the solder to a melting
heat when the pot is applied to use, inasmuch as the attached parts are entirely
submerged in the liquid contained in the pot. The metallic lining e is fastened in
the outlet B of the vessel, by a flange on its inner edge, engaging the corre
sponding edge of the outlet, as shown, and, if desirable, a second flange may be
formed on the outer edge of said lining, where it is attached to the surrounding
metallic band.
The earthenware vessel A, may be of the usual tapering form, one effect of which
is to facilitate the adjustment of the metallic band D thereon, and it is preferably
equipped with a metallic jacket S, which is attached to the band and on the lower
edge of which is a flange b, supporting a sub-button A³, of asbestos or similar
material, below the main bottom of the vessel. The vessel A has the usual
handle C, which may be attached at one end to the metallic band D and at the
other end to another similar band on the upper part of the vessel, or which may be
attached at both ends to the metallic jacket S when such is used.
In the upper part of the vessel A. is a coffee-receptacle F, it being suspended
therein, as by a flange, resting on the upper edge of the vessel, and within said
receptacle is a filter or percolator G through which the water is poured on the coffee,
and from which it discharges through an outlet o in the base of the receptacle.
Said percolator G has a hollow foraminous wall or walls G¹ which are in this
example arranged radially at an angle to each other and constructed to communicate
with said outlet o of the coffee-receptacle, so that said hollow wall or walls conduct
the infusion that may enter the channels formed by the interior of the walls,
through their foraminous sides, to said outlet, while by said angular position of the

page_text: walls relatively to each other a large area of filtering-surface is presented in a com-
paratively small space, thereby permitting the greatest possible circulation of water
through the coffee in a receptacle of a given size, with the effect of bringing the
water in intimate contact with the coffee for absorbing the entire strength thereof,
besides preventing the coffee from packing.
.
In the example shown in Figs. 1. 2. and 4 the series of filtering-walls Gare
composed of a single piece of foraminous material having two sets of return-bends
like a star, one such bend forming outer closed ends to the walls and the other
inner open ends, where the walls communicate with the outlet o of the coffee-
receptacle or with each other; but said walls may be of any other suitable
construction, and, moreover, may terminate within the side of the coffee-receptacle F,
as shown in Figs. 1 & 2, or they may be extended to join said side, as shown in
Fig. 3.
When the filter G is combined with the coffee-receptacle F, it is usually attached
to the bottom thereof in proper relation to the outlet o and closed at the top; but
it should be understood, that the filter can be used independently of said receptacle,
and in that event it is simply closed at the top and bottom, and in some cases the
top is made removable, as shown in Fig. 4, for permitting the coffee to be placed in
it instead of around it, as in the coffee receptacle. In said outlet o of the coffee-
receptacle is fitted a valve, closing in this example in an upward direction, to
which valve is connected a stem 1, which extends upwards through the filter G to a
point above the latter, where it is provided with a suitable handle. The function
of said valve is to prevent the escape of water from the coffee receptacle Fin
preparing the infusion, and in order to permit the valve to be locked in closed
position the valve-stem I has a spur arranged to engage with an incline on the
upper edge of a guide H for the stem, mounted on the filter, so that by properly
turning the stem its spur is caused to ride up on said incline, thereby drawing the
valve firmly against its seat; but it is evident that the valve may be closed by other
means.
aL
Below the outlet o of the coffee-receptacle is a cup K, forming a holder for a
sponge or its equivalent, as shown, through which sponge the water discharging
from said receptacle is caused to drain, with the effect of clarifying it, and especially
by arresting any particles of coffee that may escape through the filter. Said sponge-
holder is removably attached to the coffee-receptacle F, as to a circular flange
thereon, and, like said receptacle, the holder has an outlet o' in its base for the
downward escape of the water; or the sponge-holder may be located above said
outlet of the coffee-receptacle within the latter, and in that event the filter G may
be omitted.

COMPLETE SPECIFICATION.
Improvements in Coffee or Tea Pots and Urns.
1, CHARLES HALSTEAD, of the City of Brooklyn, County of Kings, and State
of New York, United States of America, Manufacturer, do hereby declare the nature
of my invention for IMPROVEMENT IN COFFEE OR TEA POTS AND URNS, and in
what manner the same is to be performed, to be particularly described and ascertained
in and by the following statement, reference being had to the drawings accom-
panying my Provisional Specification in which :-
Figure 1. represents a vertical central section of a coffee-pot embodying my
invention.
Figure 2. represents a perspective view of a coffee-receptacle detached, it being
partly broken away to expose the filter within it.
Figure 3. represents a horizontal section of a modification of my invention.
Figure 4. represents a perspective view of another modification thereof.

page_text: Figure 3. is an enlarged detail view showing the spout-connection with the band
and the earthenware vessel.
Similar letters of reference indicate similar parts.
Referring to the drawings, the letter A indicates an earthenware vessel forming
the body of the pot, in which vessel, near the bottom, is a lateral outlet B, provided
with a metallic spout C, of any usual or suitable shape.
For the purpose of connecting the spout C, to the vessel A, I employ a metallic
band D, which is fitted snugly on the vessel over said outlet B, it having an
opening D opposite thereto, and to which the spout is soldered or otherwise attached
at a point opposite said opening as shown.
To the metallic band D, is soldered or otherwise attached a metallic lining e,
which is fitted in the outlet B of the earthenware vessel and fastened therein, so
that the band, together with the spout C, is firmly held in position on the vessel by
means of said lining interlocking with the band, forming a strong and durable joint
and one which may be soldered without danger of exposing the solder to a melting
heat when the pot is applied to use, inasmuch as the attached parts are entirely
submerged in the liquid contained in the pot. The metallic lining e, is fastened in
the outlet B, of the vessel by a flange el on its inner edge, engaging the corre-
sponding edge of the outlet, as shown, and if desirable, a second flange may be,
formed on the outer edge of said lining, where it is attached to the surrounding
metallic band.
The earthenware vessel A. may be of the usual tapering form, one effect of which
is to facilitate the adjustment of the metallic band D thereon, and it is preferably
equipped with a metallic jacket S, which is attached to the band and on the lower
edge of which is a flange, supporting a sub-bottom A', of asbestos or similar
material, below the main bottom of the vessel. The vessel A. has the usual
handle C, which may be attached at one end to the metallic band D and at the
other end to another similar band on the upper part of the vessel, or which may be
attached at both ends to the metallic jacket S when such is used.
In the upper part of the vessel A, is a coffee-receptacle F, it being suspended
therein, as by a flange resting on the upper edge of the vessel, and within
said receptacle is a filter or percolator G, through which the water is poured on
the coffee, and from which it discharges through an outlet o in the base of
the receptacle. Said percolator G has a hollow foraminous wall or walls Gor
wings, which are in this example arranged radially or at an angle to each
other; and constructed to communicate with said outlet o of the coffee-receptacle,
so that said hollow wall or walls conduct the infusion that may enter the
channel formed by their interior, through the foraminofs sides to said outlet,
while by said angular position of the walls relatively to each other a large area
of filtering-surface is presented in a comparatively small space, thereby
permitting the greatest possible circulation of water through the coffee in a
receptacle of a given size, with the effect of bringing the water in intimate
contact with the coffee for absorbing the entire strength thereof, besides pre-
venting the coffee from packing.
In the example shown in Figs. 1, 3 and 4, the series of filtering-walls Gare
composed of a single piece of foraminous material having two sets of return bends
like a star, one such bend forming outer closed ends to the walls, and the other
inner open ends, where the walls communicate with the outlet o of the coffee-
receptacle or with each other; but said walls may be of any other suitable con-
struction, and, moreover, may terminate within the side of the coffee-receptacle F,
as shown in Figs. 1. and 2. or they may be extended to join said side, as shown in
Fig. 3.
When the filter G is combined with the coffee-receptacle F, it is usually attached
to the bottom thereof in proper relation to the outlet o and closed at the top; but
it should be understood that the filter can be used independently of said receptacle,
and in that event it is simply closed at the top and bottom, and in some cases the
top is made removable as shown in Fig. 4. for permitting the coffee to be placed in

page_text: it instead of around it, as in the coffee-receptacle. In said outlet o of the coffee-
receptacle is fitted a valve i, closing in this example in an upward.direction,.to
which valve is connected a stem 1, which extends upward through the filter G to a
point above the latter, where it is provided with a suitable.handle. The function
of said valve is to prevent the escape of water from the .coffee-receptacle Fin.
preparing the infusion, and in order to permit the valve to be locked in a closed
position the valve-stem I has a spur 1', arranged to engage with an incline on the
upper edge of a guide H for the stem mounted on the filter, so that by properly
turning the stem its spur is caused to ride up on said incline, thereby drawing the
valve firmly against its seat; but it is evident that the valve may be closed by other
means.
Below the outlet o of the coffee-receptacle is a cup K, forming a holder for a
sponge, or its equivalent, as shown, through which sponge the water discharging
from said receptacle is caused to drain, with the effect of clarifying it and especially
by arresting any particles of coffee that may escape through the filter. Said
sponge-holder K, is removably attached to the coffee-receptacle F, as to a circular
flange thereon, and, like said receptacle, the holder has an outlet o in its base for
the downward escape of the water; or the sponge holder may be located above said
outlet of the coffee-receptacle within the latter, and in that event the filter G may be
omitted.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:
1. In a coffee or tea pot, an earthenware vessel having a lateral outlet, a metallic
band fitted on said vessel with an opening opposite said outlet, a metallic spout
attached to the band at a point opposite said opening, and a metallic lining in the
outlet attached to said metallic band for holding the band, together with the spout,
in position on the vessel, as shown and described.
2. A coffee or tea pot having an earthenware vessel with a lateral opening, a
band with an opening, a spout secured to said band at said opening, a lining secured
to said band and provided with a flange bearing against the inner surface of the
vessel, said parts being combined substantially as and for the purpose set forth.
3. A coffee-receptacle having a base-outlet, a foraminous hollow wall, the openings
therein forming communication between the space in the receptacle and said outlet,
a valve in said ontlet, a valve stem extending to a point above said wall, and locking
devices for said stem, as shown and described.
4. A coffee-receptacle having a base outlet, a series of foraminous hollow walls,
the openings therein forming communication between the space in the receptacle and
said outlet, a valve in said outlet, a valve stem extending to a point above said walls,

5. A coffee or tea pot having a coffee-receptacle with an opening in the bottom
thereof, and a percolator having radial wings and covering the said opening in the
bottom of said receptacle, substantially as described.
6. A coffee-receptacle having a base-outlet a filter in said receptacle constructed
to communicate with the outlet, and a sponge-holder removably attached to said
receptacle below the outlet, as shown and described.
7. In a coffee-pot, an earthenware vessel having a lateral outlet, a metallic
surrounding band having an opening opposite said outlet, a metallic spout opposite
said opening, a metallic lining in said outlet, a metallic jacket, and a sub-bottom on
said jacket, the whole combined, substantially as shown and described.
8. A coffee or tea pot having a coffee-receptacle with an opening in the bottom
thereof, a percolator covering said opening and having a central vertical passage
leading to said opening and a valve controlling said receptacle opening, said parts
being combined, substantially as and for the purpose set forth.
9. A coffee or tea pot having the coffee receptacle provided with an outlet, a cup
or vessel communicating with said outlet and containing a sponge or its equivalent

page_text: for removing particles from the coffee, a valve for regulating the flow of coffee
from the receptacle to said cup, and a percolator in said receptacle, substantially as
shown and described.
10. In a coffee or tea pot, the combination of a main vessel, a coffee holder or
receptacle therein, a percolator in said receptacle, and a filter outside of and com-
municating with the coffee receptacle to filter the coffee after it leaves said
percolator, substantially as shown and described.
