Year: 1872

page_text: LETTERS PATENT to Philip John Davies, of Campsbourne Terrace,
High Street, Hornsey, in the County of Middlesex, Plumber and
Hydraulic Engineer, for the Invention of "AN IMPROVED REGULATING
AND SHUT OFF APPARATUS POR LIQUIDS."
Sealed the 21st March 1873, and dated the 25th September 1872.
PROVISIONAL SPECIFICATION left by the said Philip John Davies
at the Office of the Commissioners of Patents, with his Petition,
on the 25th September 1872.
I, PHILIP JOHN DAVIES, of Campsbourne Terrace, High Street,
Hornsey, in the County of Middlesex, Plumber and Hydraulic Engineer,
do hereby declare the nature of the said Invention for "AN IMPROVED
REGULATING AND SHUT OFF APPARATUS FOR LIQUIDS," to be as follows:-
This Invention for an improved regulating and shut off apparatus for
liquids, for the prevention of damage caused by the bursting of water pipes
in times of frost or otherwise, and for the prevention of water waste
generally, is an apparatus to be fixed in cisterns to the ordinary round
valves, shoe valves, spring valve, or spindle valve, to be used for the

page_text: purpose of flushing waterclosets, urinals, sinks, and lavatories, as
follows: I make two truly turned cups, or sometimes one cup, and a
plunger made to fit and work in within each other, and attach either of
the same cup or plunger to the top part of the above-named valves in
the cistern. If the plunger be attached to the valve, then the cup is
inverted upon the top of the plunger and connected with wire, chain, links,
or otherwise to the ball lever; the ball lever to be worked by any
mechanical contrivance to suit the waterclosets, urinals, lavatories, or
sinks. The object of this is to prevent the waste of water when con-
sumers neglect to shut down the handles.
This Invention further relates to another arrangement of apparatus
for the preventing of water waste, patented by myself 1871, No. 1716.
It relates to my locomotive clack and carrier, instead of having the cup
leather upon the carrier I do without it by making the carrier fit the
cylinder or tubes more perfectly. I also fit a spindle or other valve upon
the top seating of the carrier, which does away with one of the faces of
the locomotive clack. I also make the top part of my locomotive clack
cone-shaped to guide it properly against the shut off valve scating.
I also do away with the air chamber by having a long conc-shaped
spindle valve to work in the top plates of the cylinders, which prevents a
the tremor when the locomotive clack shuts the water suddenly off.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Philip John Davies in the Great Seal Patent
Office on the 25th March 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, PHILIP ?
JOHN DAVIES, of No. 7, Campsbourne Terrace, in the Parish of Hornsey,
in the County of Middlesex, Hydraulic Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-fifth day of September, in the
year of our Lord One thousand eight hundred and seventy-two, in the 8
thirty-sixth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Philip John Davies, Her special
licence that I, the said Philip John Davies, my executors, administra-
tors, and assigns, or such others as I, the said Philip John Davies, my

page_text: 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 "AN IMPROVED
REGULATING AND CUT OFF APPARATUS FOR LIQUIDS." upon the condition
(amongst others) that I, the said Philip John Davies, my executors or
administrators, by an instrument in writing under my, or their, or one
of their hands and scals, 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 Philip John Davies, do hereby
declare the nature of my said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement, reference being had to the accompanying
three Sheets of Drawings and letters of reference marked thereon, that
is to say:
-
This Invention relates to improved apparatus for the prevention of
water waste, and is especially applicable to the ordinary round valve,
shoe valve, spring valve, or spindle valve used in cisterns for flushing
waterclosets, urinals, sinks, and lavatories.
In the following description of the Drawings like letters refer to like
parts in all the Figures as far as practicable.
In Sheet 1 Figure 1 illustrates my Invention as applied to an ordinary
spindle valve. A is the body or scating of the valve; B, the valve with
its guide spindle; C. an inverted cup fixed by any convenient means to
the valve B; D, an external actuating cup, to the stem E of which the
wire of the ordinary ball lever or other actuating medium for operating
the same is attached. The cups C and D are bored to fit each other
with such accuracy as may be necessary. The valve seating A is fixed
in the outlet from the cistern in the usual manner. When the actuating
cup D is pulled up, the cup C, and consequently the valve B, are lifted
with it, as shown in the Figure. If now the actuating cup D be held up
the cup C will fall by its own weight and allow the valve B to close on
to its seating; the time that is required for the cup C and valve B to

page_text: fall within the actuating cup D, or for the cup D to fall over the cup C,
when liberated is dependent upon the space between the sides of the two
cups, the action of the apparatus being similar to that which is now well
understood in connection with water waste preventers, such for example
as those described in the Specifications of Patents granted to Alfred 5
Tylor, bearing date the 15th March A.D. 1871, No. 685; the 3rd
November A.D. 1871, No. 2948; and the 31st July A.D. 1872, No.
Figure 3 illustrates a similar method, but with the valve B formed on
Figure 3 illustrates a similar method, but with the valve B formed on
the cup C itself.
Figures 4, 5, and 6 illustrate the application of the cups to the 1
ordinary round valves as adapted respectively to the single flanged
seating, the double flanged seating, and the seating employed for iron
slate cisterns.
Figure 7 illustrates the application of the cups C and D to what is
known as a shoe valve. In this case the outer cup D acts upon the 2
waste preventing valve by its lower edge falling (if the cup C is held
up) on to the elastic seating G so as to cut off the supply as soon as a
proper quantity of water shall have passed the cup C, with the valve B
falling on to the seating A when liberated.
In Sheet 2, Figure 8 illustrates the application of the cups C and D 2
to a shoe valve in such manner as to render the apparatus double acting,
that is to say, that whether the "ball lever" be held down too long or
not long enough a certain quantity of water shall be allowed to pass
and no more. In this case the apparatus shown in Figure 7, Sheet 1, is
enclosed in a third cup or cylinder H, which is fixed, and provided with 3
an outlet valve I at the top. The actuating cup C being raised raises
also cup D, the water above the latter escaping for the most part by the
valve I. The water then flows through the openings J, J, in the cup or
cylinder H and through the seating A. If now the cup C and the
valve B be held up the cup C gradually falls on to the seating G, shutting a
off the water from the seating A. If on the other hand the apparatus

page_text: is liberated too quickly the cups C and D can only fall gradually so as
to allow the proper quantity of water to pass.
Figure 9 shows a cup open at top, fixed to an ordinary round valve
seating, and having perforations near the lower end to act as a strainer.
The valve is operated by a piston and follower, as shown.
Figures 10, 11, and 12 illustrate a method I employ in connection
with a plunger, piston, or follower, moving in a fixed cup or cylinder for
obviating the leakage of the valve B consequent upon imperfect work-
manship in setting the cup or cylinder square with the valve seating A.
It consists in connecting the said valve B to the plunger cup or follower
by a swivel ball joint M as shown, whereby the valve is allowed to take
a fair bearing on the seating whether the cup or cylinder be true thereto
or not
SMULOW Cisterns.
Figures 11 and 12 also show further arrangements and modifications
of the apparatus, which will be readily understood by inspection.
Figure 13 shows a method I employ for expanding or contracting the
plunger or follower in valves of this description in case it should become
too tight by corrosion or fouling of the cup or cylinder in which it
works, or too loose therein by wear. This I effect by employing com-
pressible washers K, K, of suitable size or thickness, which being com-
pressed vertically by tightening the nut L expand laterally, and thus
tighten the plunger or follower in the cup or cylinder; whilst if the nut
L is slackened they contract laterally, and the plunger or follower is
loosened in the cup or cylinder.
In Sheet 3, Figure 14 shows another arrangement adapted in a sunk
well for use in shallow cisterns, the valve B being attached to a cup C
actuated by a piston D working therein, the cup C being provided
with feathers P, which guide it in the well N. A strainer Q is by
preference placed over the apparatus in the cistern, as shown.
Figure 15 shows a similar arrangement in which the cup C is closed at
top and provided with a valve I and suitable apertures so as to allow of
the speed of the descent of the cup C, and the valve B being regulated
as desired.

page_text: Figure 16 shows the application of one example of my arrangements
to a cistern and service box so as to prevent waste.
It will now be readily understood that by the various means above
described ordinary round, shoe, spring, or spindle valves may be easily
adapted to act as water waste preventers, and that by these means very
great simplicity of parts is attained and greater certainty of action than
heretofore.
Having now described the nature of my said Invention and the
manner in which the same is to or may be carried into effect, I wish it
to be understood that I make no claim to the constructing generally of
apparatus acting in the manner described, as the same is well known,
but what I do claim is the means, method, and manners of adapting
ordinary, round, shoe, spring, spindle, or other similar valves so as to
act as water waste preventers, the parts being arranged, constructed,
combined, and applied substantially as herein-before described and
illustrated.
In witness whereof, I, the said Philip John Davies, have here-
unto set my hand and seal, this Twenty- day of March,
in the year of our Lord One thousand eight hundred and seventy-
three.
