Improvements in Stop Valves for Steam and the like.
EDWARD WILLIAMS, Bradley Terrace, Walker, near Newcastle-on-Tyne,
Engineer, do hereby declare the nature of this invention to be as follows:-
My invention relates to stop valves for steam & the like purposes and has
for its object valves, which are made in such a manner as to form part of the
range of pipes to which they may be placed and having no spindle projecting,
are thus much neater and more compact.
These valves may be made in any suitable metals to suit the purposes (varied)
to which the valves may be applied, such as steain, acids, gases, water and
other liquids.
.
In order that my invention may be clearly understood and more easily carried
into practice I have appended 'hereto a sheet of drawings upon which I have
fully illustrated the nature of my said improvements.
Drawings show the valve plug A, which is of the "piston valve type" on to
which is mounted a handwheel C, which on being turned opens the valve thus
allowing the steam & the like to pass.straight through the port holes E.
The valve is held non-rotative by means of collared bolts or studs D, which
also ensures the handwheel C working freely at all times, when the valve is opened
it will be well to run the valve plug A up to mitre seats G, H, which practically.
shut off any possible leak from gaining access to the outer shell and in this
way making a perfectly tight valve without the usual methods of jointing. When
the valve is closed it is made tight by mitres in the usual way.
For further security. against leakage stuffing boxes, may be fitted or packing
rings as shewn at E, F, being preferable and will generally be found satisfactory.
The valve plug A it will be seen having a projected disc B, which is screwed
round its periphery on to which the handwheel C is screwed, the handwheel C is
held in a constant position latterally by means of the bolts or studs before men-
tioned, these valves may be made with or without branches as may be required
from time to time as will' be well understood.

in and by the following statement:;
In order that my invention may be clearly understood and more easily carried
into practice I refer you to drawings sent with my Provisional Specification which
fully illustrate the nature of my said invention.
Drawings show the valve plug A, which is of the piston valve type on to
which is mounted a handwheel C, which on being turned opens the valve thus
allowing the steam and the like fluids to pass straight through the port holes E.
The valve is held, non-rotative by means of the collar bolts or studs D, which
also ensure the hand-wheel C, working freely at all times, when the valve is opened
It will be well to run the valve plug A up to the mitres seats G and H, which
practically shut off any possible, leakage, from gaining access to the outer shell
and in this way making a perfectly tight valve under all pressures without the
usual method of jointing.

The valve plug A, it will be seen having a projected disc B, is screwed on, the

in a constant position laterally by means of the bolts or studs before mentioned.
These valves may be made with or without-branches as may be required from
time to time. The valve being helds non-rotative it will be kept tight against
pressure for a longer period and having no spindle is much neater and mores
compact. When connected into a range of pipes it will be found to take up
much less space. than does the usual type of valves.
i
These valves may be made of any desired-metal to suit the varied purposes to
which it may be applied such as steam, water, acids, gases and other fluids.
Having now particularly described and ascertained the nature of my said
invention and in what manner the saine is to be performed I declare that what
1claim is:
(1) A hollow plug, non-rotative, spindle-less, direct flow perfectly tight-reliable
valve under all pressures, substantially as shown in drawings as will be well
understood.
