AN IMPROVED COCK OR TAP
Year: 1884

page_text: I REUBEN COLE of 7 Unity Street, St Philip's, in the City of Bristol, Brass-
founder, do hereby declare the nature of said invention for "AN IMPROVED COCK OR
TAP," to be as follows:-
This invention consists in an improved form of cock or tap which may be
adapted to be operated by hand or by a ball and lever. The inlet barrel is
extended through the cock and is pierced, perforated or slotted at a point
where it is surrounded by the outlet which extends around it in the form of a
channel.
To the inner end of the plunger or spindle, which may be operated by hand
or by a ball and lever, is secured a leather cup having its open end towards the
inlct.
When the said plunger or spindle is operated to present the leather cup
opposite the perforations or slots formed, as aforesaid, in the barrel of the cock, the
water-way to the outlet thereby closed, the pressure of the water acting in the
cup assisting therein.
When the spindle is moved outwards from the perforations or slots, the water-
way to the outlet is re-opened through the said perforations or slots.

page_text: I, REUBEN COLE, of 7, Unity Street St. Phillip's, in the City and County of
Bristol, Brassfounder, do hereby declare the nature of my said invention for
"AN IMPROVED COCK OR TAP". and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement-
This invention consists in an improved form of cock or tap which may be
adapted to be operated by hand or by a ball and lever.
The inlet barrel is extended through the cock and is pierced, perforated, or
slotted at a point where it is surrounded by the outlet which extends around it in
the form of a channel.
To the inner end of the plunger or spindle, which may be operated by hand
or by a ball and lever, is secured a leather cup having its open end towards the
inlet.
When the said plunger or spindle is operated to present the leather cup opposite
the perforations or slots formed, as aforesaid, in the barrel of the cock, the water-
way to the outlet is thereby closed, the pressure of the water acting in the cup
assisting therein.
When the spindle is moved in the requisite direction to withdraw the leather cup
from the perforations in the barrel the water-way is opened.
And in order that my said invention may be properly understood, I now proceed
to describe the same with reference to the accompanying sheet of drawings and the
figures and letters marked thereon:-
Fig. 1 on the accompanying sheet of drawings represents a longitudinal section
of a cock or tap constructed in accordance with my said invention and adapted
to be worked by a hand wheel. Fig. 2 is a transverse section through the per-
forations in the barrel a. The perforations, of which there are two rows, b and b¹,
in the cock shown in the drawings, communicate with the chamber c of the outlet
throat c. Instead of being perforated, as shown, the barrel a may be slotted or
otherwise pierced with orifices.
To the inner end of the spindle d is secured the leather cup e the open end of
which is towards the inlet f.
When the leather cup is presented opposite the perforations in the barrel a, as
shown in the drawings, communication between the barrel a and the outlet
chamber c is thereby closed and the pressure of the water acting in the cup assists
in closing the communication.
Upon the spindle & which is cut to form the screw is the square shoulder d'
fitting into the barrel a which is recessed correspondingly to receive it.
By turning the handwheel y in the requisite direction the spindle dis moved to
withdraw the leather cup e from the perforations b, b¹ and the water-way is thus
opened.
Instead of being of leather the cup e may be of other material suitable for
the purpose to be fulfilled thereby. The spindle d may be operated and the
waterway governed by means of a lever and ball connected thereto instead of a
handwheel and screw as described.
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 cock or tap formned of the pierced or slotted barrel a and the outlet chamber c
the communication between which by way of the orifices in the said barrel is

page_text: governed by the position therein of the cup e of leather or other suitable material
substantially as heroinbefore described and shown in the accompanying sheot
of drawings, the spindle carrying the said cup being operated oither by hand
or by a ball and lever or by other means.
