LETTERS PATENT to William Lloyd Wise, of Chandos Chambers,
Adelphi, in the County of Middlesex, Patent Agent, for the In-
vention of "IMPROVEMENTS IN STOP VALVES."-A communication from
abroad by Ernest Biega, Waterworks Engineer, of Breslau, in the
Kingdom, of Prussia.
Sealed the 29th December 1874, and dated the 25th July 1874.
PROVISIONAL SPECIFICATION left by the said William Lloyd Wise
at the Office of the Commissioners of Patents, with his Petition, on
the 25th July 1874.
I, WILLIAM LLOYD WISE, of Chandos Chambers, Adelphi, in the
County of Middlesex, Patent Agent, do hereby declare the nature
of the said Invention for "IMPROVEMENTS IN STOP VALVES," to be as
follows:-
PROVISIONAL SPECIFICATION left by the said William Lloyd Wise
at the Office of the Commissioners of Patents, with his Petition, on
the 25th July 1874.
I, WILLIAM LLOYD WISE, of Chandos Chambers, Adelphi, in the
5 County of Middlesex, Patent Agent, do hereby declare the nature
of the said-Invention-for- ¯“¯IMPROVEMENTS IN STOP VALVES," to be as
follows:-
This Invention is designed to produce a cheap, simple, efficient, and
durable stop valve which shall work without countershock of the fluid
ŉ for which it is used.

page_text: The improved valve is illustrated in the accompanying Drawings, in
which Fig. 1 is a vertical section, and Fig. 2, a horizontal section.
a is the valve box or body which is of cylindrical form closed at the
top by means of a cover, through which the valve spindle passes. The
water or fluid enters at 6 and escapes from the valve chamber at c.
The valve acts as a two-fold one, the facing a being caused to close
against the scat d*, whilst the periphery of the cylindrical part e closes
the outlet c. The valve is packed to fit the box or chamber by means of
a cup leather f.
When by means of the lever g the valve is raised, the water or fluid
entering at brushes up into the hollow valvo, where its direction is
suddenly reversed. The reaction thus produced causes the valve to
close gently and without shock.
It will be obvious that the details of construction may be modified
without departing from the distinctive characteristics of this Invention.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Lloyd Wise in the Great Seal Patent
Office on the 22nd January 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
LLOYD WISE, of Chandos Chambers, Adelphi, in the County of Mid-
dlesex, Patent Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing dato the Twenty-fifth day of July, in the year of
our Lord One thousand eight hundred and seventy-four, in the thirty-
eighth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said William Lloyd Wise, Her special
license that I, the said William Lloyd Wise, my executors, admini-
strators, and assigns, or such others as I, the said William Lloyd
Wise, my executors, administrators, and assigns, should at any time
agree with, and no others, from time to time and at all times thereafter
during the term therein expressed, should and lawfully might make,
use, exercise, and vend, within the United Kingdom of Great Britain

page_text: and Ireland, the Channel Islands, and Isle of Man, an Invention for
"IMPROVEMENTS IN STOP VALVES," a communication to me from abroad
by Ernest Biega, Waterworks Engineer, of Breslau, in the Kingdom of
Prussia, upon the condition (amongst others) that I, the said William
Lloyd Wise, my executors or administrators, by an instrument in writing
under my, or their, or one of their hands and seals, should particularly
describe and ascertain the nature of the said Invention, and in what
manner the same was to be performed, and cause the same to be
filed in the Great Seal Patent Office within six calendar months next
and immediately after the date of the said Letters Patent.
"
NOW KNOW YE, that I, the said William Lloyd Wise, do hereby
declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and by
the following statement thereof, and the Sheet of Drawings therein
referred to (that is to say) :-
This Invention is designed to produce a cheap, simple, efficient, and
durable stop valve which shall work without countershock of the fluid
for which it is used.
The improved valve is illustrated in the accompanying Drawings, in
which Fig. 1 is a vertical section, and Fig. 2, a horizontal section.
a is the valve box or body, which is of cylindrical form, closed at the
top by means of a cover, through which the valve spindle passes. The
water or fluid enters at 6 and escapes from the valve chamber at c.
The valve acts as a two-fold one, the facing d (which is shewn as
made of leather) being caused to close against the seat d*, whilst the
periphery of the cylindrical part e closes the outlet c. The valve is
packed to fit the box or chamber by means of a leather cap ƒ.
I
When by means of the lever g the valve is raised, the water or fluid
entering at 6 rushes up into the hollow valve e, e¹, where it is suddenly
caused to turn at an angle of one hundred and eighty degrees in order
to follow the opposite downward direction. The reaction thus produced
causes the valve to close gently and without shock.
This valve will be found especially applicable to waterclosets where a
water stop valve of simple and cheap construction, working without
countershock of the water, has been much wanted to obviate the
necessity for a reservoir or supply cistern.

page_text: The devices heretofore brought out in this direction and claimed as
working without countershock have so far as my foreign correspondent
knows either failed to answer the purpose even when used in conjunction
with an air vessel or other contrivances, or they have been subject to
constant disorder and have involved frequent repairs.
The improved valve is also applicable to hydrants, stand pipes, and in
all other cases where a two-fold closure, without shock, is desirable.

Ε
Having described the nature of the said Invention, and having
explained the manner of carrying the same into practical effect, as
communicated to me, as aforesaid, I hereby declaro what I consider 1
to be novel and original and therefore claim as the Invention secured
to me by the herein-before in part recited Letters Patent to be,—
1. The construction of stop valves in which the inlet is governed by
a face on the inner part of the crown of an inverted cup-shaped valve,
whose external cylindrical face governs the outlet, as and for the purpose 1
above described.
2. The combination of parts forming the improved stop valve, con.
structed, arranged, and operating substantially as shewn in and described
with reference to the Drawings..
In witness whereof. I.. the said William Lloyd Wise, have hereunto 2
above described.
2. The combination of parts forming the improved stop valve, con.
structed, arranged, and operating substantially as shewn in and described
with reference to the Drawings..
In witness whereof. L. the said William Lloyd Wise, have hereunto 20
set my hand and seal, this Twenty-second day of January, in
the year of our Lord One thousand eight hundred and seventy-
