PROVISIONAL SPECIFICATION.
Improvements in and in connection with Taps and Stop-cocks for
the Prevention of Leakage.
I, WILLIAM FREDERICK BARNARD of 1 Humbleton Villas Finchley Park North
Finchley Gentleman do hereby declare the nature of this invention to be as
follows:-
The object of my invention is to prevent the leakage of taps, stop-cocks and similar
appliances, and to enable the same to be cleansed should they become foul from any
cause. For this purpose I use a cone, preferably of india-rubber, which I insert in
any required position in the body of the tap and which may be either fixed or movable.
By the action of the handle of the tap in any required direction, the cone contracts or
expands as desired. For the cleansing of the same I form an opening, preferably in
the under part of the tap which I close by means of a thread screw and nut or similar
device. My invention is applicable for use in all kinds of taps and stop-cocks.

COMPLETE SPECIFICATION.
Improvements in and in connection with Taps and Stop-cocks for
the Prevention of Leakage.
I, WILLIAM FREDERICK BARNARD of 1 Humbleton Villas Finchley Park North
Finchley Middlesex Gentleman do hereby declare the nature of this invention and
in what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement and accompanying drawing :-
:-
The object of my invention is to prevent the leakage of taps, stop cocks and similar
appliances and to enable the same to be cleansed should they become foul from any
cause. For this purpose I use a cone preferably of india rubber, which I insert in any
required position in the body of the tap or cock, and which may be either fixed or
movable. By the action of the handle of the tap or cock in any required direction,
the cone contracts or expands as desired. For the cleansing of the same I form an
opening preferably in the under part of the tap which I close by means of a thread
screw and nut or similar device. My invention is applicable for use in all kinds of
taps and stop cocks.
In the accompanying drawing
Figures 1 and 2 exhibit views, principally in section, showing a class of tap or stop
cock such as I propose to adopt as in accordance with this my invention, but the same
may be varied to suit the particular object and purpose desired.
The following letters of reference throughout same refer to like or corresponding
parts: wherein A, is the connection end or portion for coupling same toward the
main supply pipe. B and C, are partition spaces or parts formed in the casting of the
tap or stop valve, having an opening or annular space D, suitably formed therein so
as to provide for and give a seating for the conical elastic plug E, which is connected
to and forms part or portion of the spindle F, baving a screw formed thereon which
works into a screwed thread formed in the nut or cap portion G, and the external
lower portion of the said cap G, is likewise suitably formed having a screw thread
thereon, so as to be capable of being screwed into the thread formed in the casting or
neck portion H, of the tap or stop cock. J, is a further part forming portion of the
cap or cover, having a suitable washer or washers, or packing surrounding, and when
screwed down will act as a stuffing box. K, is the finger tap or upper part of and for

page_text: actuating the working screwed spindle F. L, is the exit or delivery portion of the
tap or valve; and as will be seen in Figure 1, where the screwed spindle F, is shown
as having been actuated so as to cause the conical elastic plug E, to be withdrawn and
raised out of its seating D, so that a free and clear way is given for the liquid or
other matter under passage and pressure to flow or pass to and through the exit
opening L.
In Figure 2, the reverse action or position is shewn to have taken place, and that
the screwed spindle F, has caused the conical elastic plug to be led or forced into its
seating D, and expanded therein, and thereby giving a perfectly tight and secure
valve joint.
At the under part of the tap or stop cock an opening is provided therein and into
which a threaded screw having a nut head connection M, to facilitate either the
opening or closing of that part, to enable the internal part of the tap or stop cock
being cleansed.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed I declare that what I
claim is:-
:―
The use or employment of a cone or conically shaped plug formed wholly or partly
of india rubber or other like or similar material or compound of a flexible nature to
suitably fit and take within the body of the tap or cock so constructed for the preven-
tion of leakage therefrom substantially as in manner herein set forth illustrated
and described.
