Improvements in and relating to Taps, Valves, and the like.
We, ARTHUR SEWARD, Sanitary Engineer, and ALBERT ILLINGWORTH, Plumber, both
of 414, Upper Manor Street, King's Road, Chelsea, in the County of Middlesex, 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 relates to a device, by the use of which, taps, cocks, valves, and
similar fittings can be disconnected from water or steam pipes without allowing the
contents of the same to escape, but when connected through communication is
maintained.
Our invention consists of an improved device to be used with existing taps, valves
and the like, or constructed to form part of the same.
In order that our invention may be understood we refer to the accompanying
drawings in which similar letters of reference indicate similar parts in all the views.
Figure 1, shews in section, a water tap connected with our improved device.
Figure 2, shews an elevation of the water tap detached, with the device in section
and in the closed position.
Figure 3, is a sectional view of a combined tap and device.
Figures 4, 5 and 6 shiew details of the device."
The application of our invention to other forms of water taps, than those illustrated,
also to steam valves and other similar fittings will be readily understood without the
aid of further drawings.
Our improved device consists of a tubular body (A) having at one end a seat (B)
for a cone shaped valve (C). This valve (C) is depended from or connected with a
circular grating (D), or suitable three armed support, by means of the stem (E).
The end portion, with valve, of the body (A) has a suitable thread formed thereon,
and screws into the usual connection fitted to the pipe. The pressure of water, or
steam in the pipe actuates the valve (C) and forces it upon its seating (B); thus
closing the outlet and preventing the escape of the contents of the pipe.
The tap, valve or other fitting as the case may be, screws into the other end of the
body, and forces the grating (D) upon the shoulder or ledge (F) in the body; the
cone valve (C) at the same time is moved from its seat and opens communication
between the pipe and the tap, valve, or the like.
The valve (C) and component parts are made of suitable non-corrosive material.
The stem (E) may be furnished if necessary with guides such as (E¹) shewn in
Figures 5 and
or it may be guided in any other suitable mauner to ensure the valve
working in its proper position.
The device may be arranged vertically, horizontally or in any other position to
suit the tap or valve used.
A tap, valve, or other similar fitting can be constructed with the device to form
In this case the

body (A) forms the lower portion of the tap; the extended portion (G) screws into
this body, on to the grating (D) and binds it upon the shoulder or ledge (F). Now

page_text: when it is desired to renew say, the washer of the tap's valve and the tap is connected
with the water pipe, it is only necessary to unscrew and remove the upper portion
of the tap; the cone valve (C) being thus released instantly closes the outlet of the
pipe.
The form of taps as shewn in the drawing closes with the pressure of the fluid in
the pipe but taps of the ordinary construction can be used with our invention equally
as well.
Our invention can also be applied to pipe unions or couplings so that one pipe can
be disconnected from another or the service, at the same time the escape of the
supply is prevented.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
Firstly-A device for closing the outlet of a pipe, actuated by the pressure of the
fluid or steam therein, upon the removal of the tap, valve, or other fitting therefrom,
substantially as herein set forth.
Secondly-A device, consisting of a body (A) having a seat (B), the cone shaped
valve (C), the stem (E) with or without guides, the grating (D) or its equivalent and
the shoulder or ledge (F) substantially as and for the purposes herein set forth.
Thirdly-A combined device and tap, valve, or other similar fitting, substantially
und for the purposes herein wat fout.
