1 JAMES WALL O'TOOLE of No. 20 South Mall Cork Ireland Mechanical Engineer
do hereby declare the nature of my invention for AN IMPROVED TAP OR STOP-COCK "
to be as follows:-
This invention has reference to the production of a simple and effectual self-acting
tap or stop-cock, the construction of which will be readily understood on reference to
the accompanying sketch.
The water supply pipe is connected to the tap at a in the ordinary way, and through
a small aperture at 6 the water enters the space or chamber c, ihus causing the pressure
of the water to act on the piston d. The front of the piston has a leather or other
flexible washer e to form a water-tight joint at on the outflow Chamber g.
The action of the apparatus is as follows;-
In order to draw off a supply of water it is only necessary to press the piston rod h
so that the piston d will move from the face when the water flows from the core i
into the annular space and thence into the spout which communicates with the
annular space. Immediatly the pressure of the hand is withdrawn from the handle or
piston rod h the pressure of the water on the back of the piston d will close the tap.
This tap will suit either domestic use or it may be placed in a column or stand at a
public fountain. If required for hot water or acids the joint at ƒ can be made without
the washers and ground in the usual way.

JAMES WALL O'TOOL of No. 20 South Mall, Cork, Ireland, Mechanical Engineer
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 reference to the production of a simple and effectual self acting
tap or Stop Cock, the construction and arrangement of which will be readily under-
stood on reference to the accompanying drawing.
The ordinary supply pipe is connected to the tap in the ordinary way at a, and
through a small aperture at the water enters the space or chamber e, wherein the
pressure of the water will act on the piston d, thus keeping the tap closed. The front
of the piston is provided with a leather or other flexible washer e, for the purpose of
forming a water tight joint at f on the outflow chamber g.
The action of my improved tap or Stop Cock is briefly as follows. Having con-
nected the apparatus to the supply pipo as described in order to draw off water it is
only necessary to press the piston rod h, so that the piston d will move from the face
or seat f, when the water will flow from the core i, into the annular space k, and
thence into the spout, which communicates with the annular space. Immediately
the pressure of the land is removed from the handle or piston rod h, the pressure of
the water acting on the back of the piston will close the tap.
This apparatus will suit for either domestic use, or it may be placed in a column or
stand at a public fountain. If required for use in connection with hot water, or acids,
the joint at can be made without the washer and ground in the usual way.
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
The use and application of an apparatus for use as a tap or Stop Cock, constructed
and operating in the manner substantially as herein specified and set forth.
