Specification Accepted, 7th Apr., 1887
I WILLIAM THOMAS, of Gallewm, Port Talbot, in the county of Glamorgan,
surveyor, 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 improved cock or tap in which this invention consists is designed to be operated
through the medium of a lever pivotted towards its lower end so as to actuato a
spindle horizontally disposed and which is free to reciprocate in a barrel, and so to
govern the admission of water to the said barrel. At the rear or inner end the spindle
is contracted in diameter and terminates in a button or valve which constitutes the
plug of the cock or tap.
The spindle aforesaid is so arranged that when the cock or tap is opened to allow the
water to flow into the barrel the valve is moved back against the pressure of the water.
For the purpose of causing the lever to resume its normal position, and so to close the
cock or tap, a spring is employed. This spring is attached at one end to the inside of
a box or cover by which the principal working parts of the appliance are enclosed.
The other end of the spring bears against the lever. The closing action is assisted by
the pressure of the water acting behind the valve.
Referring to the accompanying sheet of illustrative drawings, Fig. 1 thereon
represents a vertical section, and Fig. 2 a front view, of an example of the improved
cock or tap in which this invention consists. Fig. 3 represents a horizontal section of
the barrel a, Fig. 1.
In the barrel a is a spindle 6 having an enlarged part or piston towards its front
end whereby it is guided or maintained in its proper horizontal plane. At its inner or
rear end, towards which it is contracted in diameter, is a stud or button c which
constitutes a plug or valve. It is seated at the inner or rear end of the stem or shank
by which connection is made with the supply pipe d carried into the wall e. Above
the front part of the spindle b the lever is pivotted in such manner as to enable the
spindle to be actuated thereby.
The principal working parts of the appliance are enclosed by the box or cover /
screwed or otherwise secured to the face plate i by which the cock or trap is affixed to

page_text: the wall e. At the top the box is slotted to admit of the requisite movements of the
lever fin opening or closing the water communication.
At the bottom the bib or nozzle of the tap is extended through the box h. A
spring is attached at one end to the inside of the box h and bears at the other end
against the lever f.
To admit water to the tap the lever is tilted forward and the valve e thereby forced
back. The water admitted has free circulation around the contracted part of the
spindle and passes out from the barrel a by the water-way m into the nozzle or
bib l.
To shut off the supply of water the lever is released by the operator and is
returned to its normal position by the action of the spring k. In this it is assisted by
the pressure of the water acting behind the valve c.
Having now particularly described and ascertained the nature of this invention, and
in what manner the same is to be performed, I declare that what I claim is :-
1. An improved cock or tap, for attachment to a wall or for placing in any other
suitable situation, in which the water supply is controlled by a valve such as c formed
on or secured to the inner or rear end of a spindle such as having its diameter
contracted towards that end, the spindle being free to be reciprocated or male to move
in a horizontal plane in a barrel such as a according as a lever such as pivotted above
the said spindle is operated forward. or backward to allow or prevent the admission of
water to the said barrel, substantially as herein before described with reference to the
accompanying sheet of illustrative drawings.
2. An improved cock or tap consisting of a valve spindle such as b contained within
a barrel such as a and furnished at its rear end with à valve such as c, a lever such as f
for actuating the said spindle, a spring such as k, or its equivalent, for returning the
lever to its normal position, in combination with a box or cover such as for enclosing
and protecting the principal working parts of the cock or tap, substantially as
hereinbefore described.
