the Flow of Water when Taps or Cocks are Disconnected.
I SAMUEL PAYNE DAY No. 15 Gladstone Place Lewes Road Brighton Sussex
Carpenter and Joiner do hereby declare the nature of this invention to be as
follows
:
My invention consists of a boss of brass, gun metal, or any other suitable material,
into which the cocks used for drawing water from lead or iron service pipes are
screwed having a self-closing valve inside it. This boss consists of three parts viz.
the body, the valve, and the breech.
The body has a chamber formed in it. The internal diameter of this chamber is
larger than the internal diameter of the neck into which the cock or tap is screwed
thereby forming a ledge or shoulder at the front part of the chamber and in this
ledge is turned the seating of the valve. The valve is made to fit inside the chamber
and is turned and ground to fit the seating above mentioned.
The front part of the valve is cylindrical and perforated with holes to give passage'
to the water and is made to fit inside the neck of the boss; it also has a follower or.
tail piece to guide it in the direction of the axis of the boss. The back extremity of
the body is closed by the breech, which is made with a cylindrical space into which
the tail of the valve works, and it is attached to the body, either by a screwed or
brazed joint.
.
The inlet to the boss is either made with a plain shank for attachment to the service
pipe with a plumbers joint, or with a male or female screw for attachment to iron
pipes, and is so arranged that when the tap, is removed from the boss, the pressure
of the water, pushes forward the valve to its seat, thereby preventing the flow of
water without shutting it off from any other taps. When the valve is thus closed the
cylindrical part at the front of the valve protrudes forward into the neck of the boss,
so that the act of screwing in the tap, brings the end of the tap and the front of
the valve into contact, and pushes back the valve into the body of the boss thereby.
opening the water way.
Thus the employment of this valve boss, will permit of a tap being readily removed
for any purpose without shutting off the water at the main or emptying cisterns or
boilers.

page_text: An Improved Device Chiefly Designed for Automatically Stopping
the Flow of Water when Taps or Cocks are Disconnected.
I, SAMUEL PAYNE DAY, of 15, Gladstone Place, Lewes Road, Brighton, in the
county of Sussex, Carpenter and Joiner, 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:-
My invention chiefly relates to improved means for permitting the removal of taps
or cocks from pipes connected with a boiler or other reservoir without rendering it
necessary to withdraw the water from such reservoir and without the necessity for
operating separate cocks, the improved means serving to automatically stop the flow
of water through the outlet from which the tap or cock is removed. My invention
is however also applicable-for-permitting two or more pipes or tubes to be disconnected
for the purpose above mentioned.
In order to enable my invention to be fully understood I will describe how it
can be carried into practice by reference to the accompanying drawing, in which
Figure 1 is a section of an apparatus constructed according to my invention and
-suitable for use with a tap or cock in connection with which it is shown.
Figure 2 is a section of the apparatus shewing the position of the valve when-the
tap is removed.
Figure 3 is an elevation of the valve detached.
Figure 4 is a section illustrating the use of my apparatus at the joint of two pipes
or tubes, the parts of the joint being fitted together.
Figure 5 is a similar view shewing the position assumed by the valve when the
joint is unscrewed.
Similar letters in all the figures indicate similar parts.
The apparatus as shown in Figure 1 comprises a body a, a valve c and a breech or
closing piece d.
The body a forms a chamber of an internal diameter greater than that of the neck e of
the same into which the tap or cock is screwed, thereby forming a shoulder a¹
constituting the seating of the valve c.
The inlet to the body a is made with a plain shank b to enable it to be attached to a
lead service pipe by means of a Plumber's joint. Or it can be formed with a screw
thread to allow of its being connected to an iron pipe. Part of the valve c is recessed
as shown at and loosely fits the neck e. It is also provided with holes b¹ to afford a
passage for the water into the recess. Beyond this part the valve is formed of larger
diameter to fit the chamber a and with a shoulder g which is turned and ground to fit
the shoulder or valve seating at. For the purpose of guiding the valve in the direction
of the axis of the chamber a it is provided with a tail or spindle moving in a
correspondingly shaped recess in the breech or closing piece d' which is attached to
the body a by a screwed or a brazed joint. The valve is in this manner guided at
both ends and cannot leave its guides and is consequently held in suspension in the
water so that the water can pass through the valve at any part thereof.

page_text: By this arrangement when the tap A is screwed into the neck e of the chamber a
it will force back the valve c from its seat into the position illustrated in Figure 1
and the water, when the tap is turned on, will flow through the lateral openings 61
into the recess and out of the tap A. It will be observed that no additional device
is required on the inner end of the tap to operate on the valve as the peculiar con-
struction of the latter obviates this necessity. Should the tap A be removed the
pressure of the water will immediately force the valve c to its seat a¹ as shown in
Figure 2 and thereby stop the flow of water.
In this manner my improved apparatus allows of a tap being removed for any
required purpose without having to shut off the water at the main or to empty the
cistern or boiler.
The adaptation of my apparatus to a pipe joint will be readily understood by
reference to Figures 4 and 5. The construction and arrangement of the parts are
the same as those illustrated in Figures 1 and 2 except that the valve c is kept away
from its seat a' by the spigot end of the pipe B instead of by a tap. i is the hexagonal
cap of the union adapted to be screwed over the neck e extending from the
chamber a.
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 :-
1. An apparatus for automatically stopping the flow of water upon the removal of
a tap or the disconnection of two or more pipes or tubes, comprising a chamber of
larger internal diameter than that of the neck or socket which receives the spigot
of the tap or pipe, thereby forming a shoulder or a seating in the chamber for a
valve which is recessed and provided with lateral holes opening into the recess, the
said valve being adapted to be kept away from its sent by the spigot end of the tap or
pipe when fixed in or on the neck of the chamber, substantially as and for the purpose
herein before described.
2. The improved apparatus for automatically shutting off the flow of water upon
the removal of taps from pipes or the disconnection of two or more pipes or tubes
as herein before described and illustrated in the accompanying drawing.
