Sealed the 18th June 1872, and dated the 20th April 1872.
PROVISIONAL SPECIFICATION left by the said Francis. George Fleury
and Alfred Tylor at the Office of the Commissioners of Patents,
with their Petition, on the 20th April 1872.
We, FRANCIS GEORGE FLEURY, of No. 24, Merrick Square, South-
wark, in the County of Surrey, Engineer, and ALFRED TYLOR, of No. 2,
Newgate Street, in the City of London, Brass Founder, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN WATER-
WASTE PREVENTERS OR APPARATUS FOR CONTROLLING AND ARRESTING THE FLOW OF
LIQUIDS," to be as follows:-
This Invention has for its object improvements in water-waste pre-
ventors or apparatus for controlling and arresting the flow of liquids,

page_text: and consists in the application and adaptation of an elastic cap, tube,
or chamber for the purpose of relieving the valve of the apparatus by
reducing that pressure against its surface, whereby it is kept against
its seat, so that on such pressure being so reduced the excess of pressure
of the liquid in the main body of the apparatus against the valve shall
cause the valve to leave its seat, thereby opening the aperture or way
and allowing the liquid to flow through and out of the apparatus. A
stem or piece may be provided in connexion with the elastic cap, tube,
or chamber for the purpose of ensuring the closing of the valve in case
of obstruction.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Francis George Fleury and Alfred Tylor in the
Great Seal Patent Office on the 19th October 1872.

TO ALL TO WHOM THESE PRESENTS SHALL COME, we, FRANCIS
GEORGE FLEURY, of No. 24, Merrick Square, Southwark, in the County :
of Surrey, Engineer, and ALFRED TYLOR, of No. 2, Newgate Street, in
the City of London, Brass Founder, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twentieth day of April, in the year of
our Lord One thousand cight hundred and seventy-two, in the thirty-
fifth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto us, the said Francis George Fleury and Alfred Tylor,
Her special license that we, the said Francis George Fleury and Alfred
Tylor, our executors, administrators, and assigns, or such others as we,
the said Francis George Fleury and Alfred Tylor, our 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 and Ireland,
the Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS
IN WATER-WASTE PREVENTERS OR APPARATUS FOR CONTROLLING AND ARRESTING
THE FLOW OF LIQUIDS," upon the condition (amongst others) that we, the
said Francis George Fleury and Alfred Tylor, our executors or admi-
nistrators, by an instrument in writing under our or their hands and
seals, or under the hand and seal of one of us or them, should particu-

page_text: .
larly 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 we, the said Francis George Fleury and Alfred
Tylor, 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 Drawing
therein referred to :-
This Invention has for its object improvements in water-waste pre-.
venters or apparatus for controlling and arresting the flow of liquids,
and consists in the application and adaptation of an elastic cap, tube,
or chamber for the purpose of relieving the valve of the apparatus by
reducing that pressure against its surface, whereby it is kept against
its seat, so that on such pressure being so reduced the excess of pressure
of the liquid in the main body of the apparatus against the valve shall
cause the valve to leave. its seat, thereby opening the aperture or way
and allowing tho liquid to flow through and out of the apparatus. A
stem or piece may be provided in connexion with the elastic cap, tube,
or chamber for the purpose of insuring the closing of the valve in case
of obstruction.
The accompanying Drawing shews in contral longitudinal vertical
section an apparatus constructed according to our Invention.
a is the body; b, the inlet; c, the outlet; d, the valve seat which
rises from a diagonal diaphragme cast across the outlet portion of the
body a; fis the moveable plug or valve which fits so as to move easily
within the central tubular portion g of the body and is provided at its
lower end with an india-rubber or other suitable valve packing h; i is
the clastic, cap, tube, or chamber which is held down in its place by the
metal cap k which screws down into the body a, and holds the lower
portion of the clastic cap tube or chamber water-tight by means of its
flange; is the the actuating handle provided with a screwed spindle m,
whose lower end fits within a plate n, so that the spindle can be turned
without turning the plate, but the lower end of the spindle is burred out
'so as to prevent its being withdrawn from the plate.
gun
The action of the apparatus is as follows:-In the positions of the
parts shewn in the Drawing the passage or way through the apparatus

page_text: is closed. By screwing down the handle 2 the plate n will be caused to
press on the top of the elastic cap, tube, or chamber until the stem o
is pressed against the top of the plug thereby forcing the liquid from
the elastic cap, tube, or chamber down between the moveable plug
or valve and the tubular portion 9 of the body back into the inlet
or main b. On now turning the handle the reverse way, so as to raise
the spindle m and plate n, the pressure of the liquid in 6 will force
up the moveable plug or valve f, and with it the elastic cap, tube, or
chamber i, thereby allowing the fluid to flow through the valve seat d
into the outlet c, which flow will continue until the plug has fallen so 1
as to close the valve seat orifice, the elastic cap, tube, or chamber
becoming in the meanwhile charged with liquid which passes up between
the plug and the tubular portion g of the body. The amount of liquid
to be passed on using the apparatus may be arranged by adjusting the
height to which the moveable valve or plug is raised, and the looseness
of the "fit" of the same in the part in which it works, a greater quantity
being passed when the lift is great and the "fit" close, and a less
quantity when the lift is small and the fit loose.
Having described our Invention of "Improvements in Water-waste
Preventers or Apparatus for Controlling and Arresting the Flow of
Liquids," and having explained the manner of carrying the same into
practical effect, we desire to state that we do not limit or confine our
use of clastic caps, tubes, or chambers as described to apparatus of the
precise form shewn in the Drawing, but what we consider to be novel
and original and therefore claim as the Invention secured to us by the
herein-before in part recited Letters Patent is, the constructing water-
waste preventers or apparatus for controlling and arresting the flow of
liquids, with elastic caps, tubes, or chambers, substantially as and for the
purposes specified.
In witness whereof, we, the said Francis George Fleury and Alfred :
Tylor, have hercunto set our hands and scals, this Nineteenth
day of October, in the year of our Lord One thousand cight
lundred and seventy-two.
