FRANCIS JAMES WARREN, of 253, Coronation Road, Bristol, Mechanical Engineer,
and HENRY BRECKNELL, EDWARD MAY MUNRO, and HUGH INNES ROGERS, all of
Edinburgh Chambers, Baldwin Street, Bristol, Electrical and Mechanical Engin-
eers, do hereby declare the nature of this invention to be as follows:-
Our invention has for its object a means of constructing a stop or regulating
valve, or a stop and regulating valve to be contained within the circumferential
walls of the pipe or branch in connection with which this valve is intended to
work, and the said valve to be operated by the pipe or branch or portion of that
pipe or branch being partly or wholly rotated about its own axis.
We prefer to construct this valve in the following manner: The pipe or
branch to be rotated is jointed by means of an ordinary stuffing box or stuffing
boxes and glands, or any modification of same, in order that that portion of the
pipe which operates the valve (the valve here is referred to as in distinction to its
seat which is formed upon the adjoining portion of the pipe or branch) may turn
freely about the adjoining portion of pipe referred to. The valve seat may be
formed upon its adjacent portion of pipe by slightly contracting the end of that
pipe so as to leave an annular space between it and the circumferential wall, of
the portion of pipe carrying the valve.
The portion of the pipe carrying the valve has a bridge across its diameter; this
bridge carries the valve itself, upon, which is formed an extension screw threaded
and engaging in a nut formed in that portion of the pipe upon which the valve
seat is formed.
The whole of the parts above described are constructed so that the joint or
joints between the rotating pipe and that portion round which it revolves shall
be free from leakage and the pipe be allowed to move freely in a circumferential
direction and also parallel with its axis.
The valve and screw attached to it is revolved with this pipe by means of its
connection with the bridge referred to and the screw thread engaging in the nut
which is situated below or behind the valve seat in the adjoining portion of the
pipe causes the valve to approach or recede from its seat as the portion of pipe
carrying the valve revolves relatively with its seat, and the whole is contained
within the circumferential walls of the two or more pipes respectively..
The form of valve may be that ordinarily approved for any specific purpose
and is dependent upon the nature of the substance or gases dealt with..
This valve may be applied to an outlet such as a branch pipe for fire hose,.or
sanitary and domestic fittings of a similar nature, or it may be used as a stop and
regulating valve in a pipe line, and the fundamental principles of its construction

liquid or gas.

Improved Combined Stop and Regulating Valve for Liquids and
Gases.
We, FRANCIS JAMES WARREN, of 253, Coronation Road, Bristol, Mechanical
Engineer, and HENRY BRECKNELL, EDWARD MAY MUNRO, and HUGH INNES ROGERS,
all of Edinburgh Chambers, Baldwin Street, Bristol, Electrical and Mechanical
Engineers, 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:---
Our invention has for its object a means of constructing a stop or regulating
valve or a stop and regulating valve to be contained within the circumferential
walls of the pipe or branch in connection with which this valve is intended to
work and the said valve is to be operated by the pipe or branch or portion of that
pipe or branch being partly or wholly rotated about its own axis.
In order that our said invention, the methods of constructing and the arranging
of the same and the manner of its working may be the better understood we have
hereto appended a sheet of drawings.
Fig. I is a sectional view through the centre of a branch pipe used in con-
nection with hose for fire domestic or sanitary purposes and shows the method we
employ to construct our valve.
The portion of the pipe marked A carries the valve B which is secured to a
bridge C cast on the pipe A.
The valve B has a square shank which fits loosely in the bridge and carries on
its outer end a nut which is screwed up to its proper position and locked there
by a split pin or other suitable device.
The bridge carries the valve loosely in order that it may adjust itself to the
seat D and bear thereon with a uniform pressure.
The valve seat D is formed upon the contracted end of the pipe E. This con-
traction provides an annular space for the escape of the liquor or gas when the
I valve is open.
The valve B has a stalk or extension on its underside which is screwed and
engages in a bridge F cast in the pipe E and tapped and screwed to receive it.
A collar or stop G is attached to the end of the screwed spindle or stalk and
prevents the valve from being overwound and so disuniting the pipes E and A.
It is preferred that the valve B should close against the pressure in order that
when shut the joint which is made between the pipes E and A may be relieved
of pressure.
The joint between the pipes A and E is formed by an ordinary stuffing box H,
having a gland nut I with loose gland J and the packing we prefer to use is an
hydraulic hat leather, which may be of any approved material according to the
nature of the fluid or gas to which it is exposed.
Figure II shows the arrangements of construction of the valve when used in
a straight pipe line.

page_text: This is similar to the detail of Fig. I and the same letters of reference apply
but in this case there is an additional stuffing box on the pipe A to connect it by
a tight joint to the continuing portion of the pipe E, which is marked El and
has a beaded end L to prevent it from blowing out when under pressure.
Our valve is operated in the following manner-
The drawings show the valve B closed against the pressure of the fluid or gas
in pipe E. When it is desired to make connection from pipes E to A, or as in
Fig. II from E to E-1, the hand wheel K which is mounted upon the pipe A is
rotated or partly rotated and turns with it the valve B, the screwed stalk of which,
being engaged with the screwed bridge F causes the valve to rise from its seat in
proportion to the pitch of thread and the amount of revolution, which may be
regulated to give a full way from one pipe to the other.
The stuffing boxes H and H, with their parts complete as shown preserve
tight joints between pipes A and E and E 1.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is:-
The application of the valve, constructed as shown in our drawings, in com-
bination, for the following purposes, as a stop or regulating valve, or a stop and
regulating valve, or stop valves in branch pipes or hose pipes for fire, domestic,
sanitary or manufacturing purposes, steam pipes, water pipes, or pipes carrying
any substance, liquid, or gas, requiring to be controlled by a stop or regulating
valve.
