I WILLIAM HENRY PIKE of 107 Walton Street London S.W. Bellmaker do
hereby declare the nature of this invention to be as follows :—
The object of my invention is to facilitate the pouring out of liquids from vessels
such as tea pots &c. I accomplish this in the following manner. I have a hollow
cylinder moving vertically in vessel and fitting somewhat closely to the upper part of
the vessel. The cylinder has a closed top and in this upper part there is a hole with
a moveable knob or handle with apertures so arranged that when it is drawn up
there is an influx of air but on thrusting it down the hole or aperture in the knob is
closed and so the pressure on the confined air is communicated to the surface of the
liquid and so forces out the liquid from the bottom or other portion of the vessel
through the spout.-One of the advantages of this arrangement is that the fingers
are not exposed to the action of the vapour also that the vapour is not allowed to
escape and prevents the influx and circulation of cold air and so prevents the cooling
of the liquid.

Improvements in Tea Pots, Coffee Pots, and other similar Vessels.
I WILLIAM HENRY PIKE of 46 Grainger Street West Newcastle upon Tyne Bell-
maker 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 :-
The object of my invention is to facilitate the pouring out of liquids from vessels
such as Tea Pots &c. I accomplish this in the following manner. I have a hollow
cylinder moveing verticaly in vessel and fitting somewhat closely to the upper part of
the vessel. The cylinder has a closed top and in this upper part there is a hole with
a moveable knob or handle with apertures so arranged that when it is drawn up there
is an influx of air but on thrusting it down either by a spring or from its own weight
or by pressure from the hand the hole or aperture in the knob is closed and so the
pressure on the confined air is communicated to the surface of the liquid from the
bottom or other portion of the vessel through the spout.
One of the advantages of this arrangement is that the fingers are not exposed to
the action of the vapour also that the vapour is not allowed to escape and prevents
the influx and circulation of cold air and so prevents the cooling of the liquid.
In the drawing the figure is a vertical section through the Tea Pot Ram and valves
in which.-
a, is the cylindrical part or Ram.
6 the Teapot or other vessel.
c the Knob fixed on spindle.
d the Spindle.
e the valve.
f the Air Passage.
g the Spring to force valve down.
h the guide fixed into Ram for Spindle.
Pin to prevent Spindle turning.
k the orifice or spout of vessel.
The operation of supplying liquid from the vessel may be thus described. The
cylindrical part or Ram a is drawn upwards out of the Teapot or vessel 6 by laying
hold of and drawing upwards knob c which is attched to spindle d on the end of
which there is a mitre or other valve e which on being thus opened allows an influx
of air through air passage f into the vessel and so prevents the fluid being raised
by suction in the vessel. The cylindrical part or Ram a being sufficiently raised the
knob is released from the hand the weight of the knob and spindle or the action of
the Spring g upon the valve or both combined close the valve and the weight of the
ram acting on the enclosed air or steam in vessel induces a pressure which forces the

page_text: liquid from an aperture or spout and so the liquid is discharged and thus the operations
may be represented as desired. The apparatus thus becoming a self pouring teapot
or other self pouring vessel. A plug or key or other valve may be used if prefered.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be carried out and performed,
I declare that what I claim is
1st. The use of Valve Spring or weight so as to render the apparatus self pouring
as described.
2nd. The prevention of cooling of the liquid by preventing the admission of air
and the exit of steam as described or by any form of valve.
3rd. Immunity from scalding the hand by the use of the valves mentioned.
