I, CHARLES JONES, of 24 Eastcheap, in the City of London, Builder, do hereby
declare the nature of this invention to be as follows:-
This invention has for its object improvements in apparatus for making infusions.
The apparatus has three principle parts:-a receiver, a holder for the material to
be infused, and a cover-The receiver is preferably of a globular form, open at the
top, and of a capacity to contain one cup or any set quantity of tea, coffee or other
material from which the infusion is to be made. At the bottom the receiver is
provided with a tap for drawing off the infusion when made. Upon the top of this
receiver the holder for the tea, coffee or other material is supported, and to make a
tight joint between the top of the receiver and the bottom of the holder an annular
projection is provided upon the former and it enters a corresponding groove around
the bottom of the latter.
The tea or coffee holder has a bottom of perforated metal upon which a disc of felt
or woven fabric with fleecy surface is supported; it also has a handle by which it
can be readily removed from the apparatus to be emptied and replaced when charged
with fresh material.
The cover is connected by a hinged joint with the receiver, and this cover fits,
when closed, (not on to the receiver itself but) on to the top of the tea or coffee
holder, when this is in place. The cover fits with a tight joint on to the top of the
holder in the same way that the holder itself fits tightly on to the top of the receiver.
There is a lug on the cover with a slotted hole through it, and a cam-like hook to
engage with it is provided upon the receiver. The hook can be turned by means of
a handle and so made to draw the parts together so as to close both of the joints
tight and capable of resisting pressure.
.
The cover above described is fixed horizontally upon the end of a pipe through
which boiling water from a boiler maintained under light pressure can be introduced.
I use preferably a boiler such as is described in the Specification of a Patent granted
to me No. 13952 in the year 1884.

page_text: When water is allowed to pass from the boiler to the apparatus the water entering
the tea or coffee holder descends upon its contents and forces its way through the
bed of tea or coffee and through the filtering material into the receptacle. An air
valve is provided upon the receptacle to allow the air to escape as the liquid enters it.
A floating valve is used and when the liquid rises it carries the valve up to its seat
and closes the vent. When the vessel is full the supply of water to the apparatus is
closed and the tap at the bottom of the apparatus is opened and the cup of tea or
coffee is drawn off.
On the inside of the cover I apply a valve over the mouth of the pipe through
which the supply of hot water enters-the valve is made to open whenever the
apparatus is closed by its lid and to close whenever the apparatus is opened so that if
the apparatus were opened without previously shutting off the supply of boiling
water to it there would be no escape of water from the boiler.
The admission of boiling water to the apparatus may be controlled by any ordinary
tap on the pipe leading from the boiler but preferably I mount a number of the
apparatus on the ends of pipes which extend radially from the plug of a tap carried
at the top of a standard which forms the water supply pipe and I form the tap in
such manner that when the assemblage of infusion making apparatus is turned
around the standard boiling water enters each apparatus as it is carried through one
part of the revolution and shut off from it at another part.

page_text: I, CHARLES JONES, of 24 Eastcheap, in the City of London, Builder, 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 has for its object improvements in apparatus for making infusions.
The apparatus has three principle parts:-a receiver, a holder for the material to
be infused, and a cover. The receiver is preforably of a globular form, open at the
top, and of a capacity to contain one cup or any set quantity of tea, coffee or other
material from which the infusion is to be made. At the bottom the receiver is
provided with a tap for drawing off the infusion when made. Upon the top of this
receiver the holder for the tea, coffee, or other material is supported, and to make a
tight joint between the top of the receiver and the bottom of the holder an annular
projection is provided upon the former and it enters a corresponding groove around
the bottom of the latter.
The tea or coffee holder has a bottom of perforated metal upon which a disc of felt
or woven fabric with fleecy surface is supported; it also has a handle by which it
can be readily removed from the apparatus to be emptied and replaced when charged
with fresh material.
The cover is connected by a hinged joint with the receiver, and this cover fits, when
closed, (not on to the receiver itself but) on the top of the tea or coffee holder, when
this is in place. The cover fits with a tight joint on to the top of the holder in the
same way that the holder itself fits tightly on to the top of the receiver. There is a
lug on the cover with a slotted hole through it, and a cam-like hook to engage with
it is provided upon the receiver. The hook can be turned by means of a handle and
so made to draw the parts together so as to close both of the joints tight and capable
of resisting pressure.
The cover above described is fixed horizontally upon the end of a pipe through
which boiling water from a boiler maintained under light pressure can be introduced.
I use preferably a boiler such as is described in the Specification of a Patent granted
to me No. 13952 in the year 1884.
When water is allowed to pass from the boiler to the apparatus the water entering
the tea or coffee holder descends upon its contents and forces its way through the bed
of tea or coffee and through the filtering material into the receptacle. An air valve
is provided upon the receptacle to allow the air to escape as the liquid enters it.
A floating valve is used and when the liquid rises it carries the valve up to its seat
and closes the vent. When the vessel is full the supply of water to the apparatus is
closed and the tap at the bottom of the apparatus is opened and the cup of tea or
coffee is drawn off.
On the inside of the cover I apply a valve over the mouth of the pipe through
which the supply of hot water enters the valve is made to open whenever the
apparatus is closed by its lid and to close whenever the apparatus is opened so that if
the apparatus were opened without previously shutting off the supply of boiling
water to it there would be no escape of water from the boiler.

page_text: The admission of boiling water to the apparatus may be controlled by any ordinary
tap on the pipe leading from the boiler but preferably I mount a number of the
apparatus on the ends of pipes which extend radially from the plug of a tap carried
at the top of a standard which forms the water supply pipe and I form the tap in such
manner that when the assemblage of infusion making apparatus is turned around the
standard boiling water enters cach apparatus as it is carried through one part of the
revolution and shut off from it at another part.
In order that my said invention may be fully understood and readily carried into
effect I will proceed to describe the drawings hereunto annexed.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a side elevation of apparatus constructed according to my invention; it
is mounted on a standard or support which latter is represented partly in section.
Figure 2 is a front elevation showing the apparatus full size.
Figure 3 is a side elevation of the receiver separated from the other parts.
Figure 4 is a plan and Figure 5 is a vertical section of the receiver.
Figure 6 is a plan of the holder.
Figure 7 is an elevation-Figure 8 is a vertical section and Figure 9 is an
underside view of the holder.
Figure 10 is a plan of the cover. Figure 11 is an elevation Figure 12 is a
vertical section and Figure 13 is an underside view of the cover with part removed.
a is the globular receiver-a¹ is the tap for drawing off the infusion-a² is the air
outlet a³ is the floating-valve which closes this outlet when the receiver is full. The
valve is of cork, a wire passes through it and enters a guiding hole at the bottom of
the valve chamber; the wire also enters the outlet a² so that the valve is effectually
controlled in its rise and fall. When the valve closes the outlet the pin projects and
is visible from the exterior; it thus serves as an indicator. a is a stud on the body
of the receiver, it receives the locking hook 6 and this is retained in place upon the
stud by
a screw entering a garter groove around the stud. is the handle by
which the hook is turned. a is the annular projection at the top of the receiver
which entering a corresponding recess in the bottom of the holder makes a tight
joint. a is the arm of the receiver to which the cover is jointed. c is the holder
into which the coffee or tea is placed c¹ is its handle, c³ is a perforated metal bottom
which is soldered in. Before the bottom is fixed however a ring c³ covered with a
fleecy cotton fabric is inserted and it is driven in up to a shoulder. c* is the cavity
at the bottom of the holder which receives the projection as on the receiver; an india
rubber ring is placed within this cavity. is the projection at the top of the holder
which enters a cavity in the cover to make a joint. d is the cover. d is the pipe on
the cover by which the hot water is supplied and this pipe serves also to carry the
apparatus. is the recess in the cover which receives the projection c³ upon the
holder into this recess an india rubber ring is placed. is the arm of the cover
which is jointed to the arm a of the receiver-d is the loop on the cover which
receives the hook by which the parts of the apparatus are locked securely together.
do is the automatic valve for closing the water inlet when the apparatus is open; it
is attached to a lever the end of this lever projects into the recess d² so that the
top of the holder presses upon it when the apparatus is closed. d' is a covering of
wire gauze soldered in over the automatic valve.
In Figure 1 taps e are shown for supplying the hot water to the apparatus and for
turning it off, but these taps need not be provided if as the drawing indicates the
apparatus be carried by a conical ring ƒ fitting over a corresponding cone on a standard
through which a water supply pipe g is led. The pipe g terminates in an opening in
the cone and when the pipe d comes to this opening the water (which is under a
light pressure) passes in, whilst when the pipe d' does not correspond with the opening
the water is cut off. It is convenient that the cone should be grooved so that a large
part of the circle is available for filling whilst a smaller part is reserved for
drawing off.
