THOMAS PENN, of No. 40, Westbury Street, Wandsworth Road, in the County
of Surrey, Engineer, and GRANVILLE SHARP ULLATHORNE, of No. 12, Bolingbroke
Grove, Wandsworth Common, in the County of Surrey. "IMPROVEMENTS IN
VALVES OR COCKS, AND IN APPARATUS FOR OPENING AND CLOSING VALVES
OR COCKS, WHICH IMPROVEMENTS ARE PARTICULARLY APPLICABLE TO THE PRE-
VENTION OF WASTE OF WATER."
Our Invention has for its objects the construction of a valve or cock, so as to be
efficient and tight when closed, and of an apparatus for regulating the opening and
closing of a valve or cock, so as to cause it to close gradually without jerking, and
to ensure the supply of a certain quantity of water or other fluid each time the
valve or cock is fully opened, and also to prevent the waste of water or other
fluid.
We construct our valve or cock in such manner that the pressure of the water or
other fluid presses the valve to its seat, and we make the valve and seat of conical
form; the valve is therefore tight when closed, and leakage is prevented, and the
form of the valve and seat also tends to prevent any grit or other substance
lodging on them.
We construct our apparatus for regulating the opening and closing of a valve or
cock in such a manner as to ensure the discharge of a certain quantity of water or
other fluid each time the valve or cock is fully opened, for which purpose we
connect a lever to the spindle of the valve, attached to which lever near its end, or
at any other suitable part of it, is a weight which closes the valve; this weight is

page_text: prevented from closing the valve suddenly, and until a certain quantity of water or
other fluid has been discharged, by means of a cylinder or tube filled with oil or
other suitable fluid, in which work a piston, the rod of which is attached to the
before named lever, the piston attached to the rod is prevented from moving
rapidly in the direction to close the valve, in consequence of the oil or other suitable
fluid in the cylinder only being able to pass from one side of the piston to the other
very slowly, either through a small hole in the piston and piston-rod, or otherwise
in the direction to allow the valve to be closed.
In order to prevent more than a certain quantity of water or other fluid from
passing through the valve or cock each time it is opened, we arrange a second
lever to work under or against the first named lever, to which second lever also is
connected a piston-rod and piston working in a cylinder or tube, and a balance
weight; this cylinder or tube is constructed similarly to the first named cylinder or
tube, but it is prevented from moving rapidly in the opposite direction; to the base
of this cylinder or tube is attached either directly or indirectly, the handle or other
arrangement for opening the valve or cock.
By this apparatus, when the cylinder connected by its piston-rod to the second
lever is moved by the handle or other arrangement in order to open the valve or
cock, the second lever moves the first lever, and so opens the valve or cock, and the
second lever, not being fixed in one with the first lever, if the handle or other
arrangement be quickly returned to its original position, the valve or cock will
still remain open, until a certain quantity of water or other fluid has been discharged,
but if the handle or other arrangement be held in the position to which it had been
moved in order to open the valve or cock, the first lever will, by reason of the
weight attached to it, act on the second lever, and the cylinder or tube arrangement
connected to the second lever will allow the valve to be gradually closed.
By this apparatus therefore the valve or cock will discharge immediately a
certain quantity of water or other fluid every time it is opened, but the valve or
cock cannot be held open beyond a certain time.
In the application of this apparatus to water-closets, we attach the base of the
cylinder or tube which is connected by its piston-rod to the second lever, to a piece
of metal working on a slide, and to which piece of metal we fix or clamp jaws,
adjustable or otherwise, which jaws engage with the lever of the pan of the closet,
and in the case of water-closets where no after flush is required we can dispense
with the first named cylinder or tube.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said Thomas Penn and Granville Sharp Ullathorne in the Great Seal
Patent Office on the 21st November 1879.
THOMAS PENN, of No. 40, Westbury Street, Wandsworth Road, in the County of
Surrey, Engineer, and GRANVILLE SHARP ULLATHORNE, of No. 12, Bolingbroke
Grove, Wandsworth Common, in the County of Surrey, Engineer. "IMPROVEMENTS
IN VALVES OR COCKS, AND IN APPARATUS FOR OPENING AND CLOSING VALVES
OR COCKS, WHICH IMPROVEMENTS ARE PARTICULARLY APPLICABLE TO THE PRE-
VENTION OF WASTE OF WATER."
Our Invention has for its objects the construction of a valve or cock, so as to be
efficient and tight when closed, and of an apparatus for regulating the opening and
closing of a valve or cock, so as to cause it to close gradually without jerking, and
to ensure the supply of a certain quantity of water or other fluid each time the
valve or cock is fully opened, and also to prevent the waste of water or other
fluid.
The accompanying Drawing represents an elevation of an apparatus and valve
constructed according to our Invention, one half of the valve chest V being shewn
in section.
We construct our valve or cock v in such manner that the pressure of the water
or other fluid represented in direction by the arrow in the Drawing, presses the
valve to its seat y, and we make the valve vand seat y of conical form; the valve
is therefore tight when closed, and leakage is prevented, and the form of the valve
and seat also tends to prevent any grit or other substance lodging on them.
We construct our apparatus for regulating the opening and closing of a valve or
cock in such manner as to ensure the discharge of a certain quantity of water or
other fluid each time the valve or cock is fully opened, for which purpose we
connect a lever to the spindle t of the valve v; this lever 7 works on a fulcrum f,
and has attached to it near its end, or at any suitable part of it, a weight w which
closes the valve v; this weight w is prevented from closing the valve v suddenly,
and until a certain quantity of water or other fluid has been discharged by means
of a cylinder or tube c filled with oil, or other suitable fluid, in which works a
piston, the rod r of which is attached to the before named lever 1, the piston
attached to the rod is prevented from moving rapidly in the direction to close
the valve, in consequence of the oil or other suitable fluid in the cylinder c only
being able to pass from one side of the piston to the other very slowly, either
through a small hole in the piston and piston rod, or otherwise in the direction to
allow the valve v to be closed.
In order to prevent more than a certain quantity of water or other fluid from
passing through the valve or cock each time it is opened, we arrange a second
lever m to work under or against the first named lever ; this second lever m
works on a fulcrum g, and is connected with a piston rod q and piston working in
a cylinder or tube d, and has a balance weight x; this cylinder or tube d is con-
structed and arranged similarly to the first named cylinder or tube c, but its
piston is prevented from moving rapidly in the opposite direction; to the base of
this cylinder or tube d is attached, either directly or indirectly, the handle or other
arrangement for opening the valve.
In the application of this apparatus to a watercloset, as represented in the
Drawing, we attach the base of the cylinder or tube d, which is connected by its
piston rod g to the second lever m, to a piece of metal working on a slide or slides
in the Drawing; this piece of metal is a cylinder e working on a cylindrical slide
piece s attached to or in one with the bedplate B. To the cylinder e we fix or
clamp jaws j,j, adjustable or otherwise, which jaws j, j, engage with the lever of
the pan of the closet.

page_text: "
By this apparatus, when the cylinder e, and with it the cylinder d connected by
its piston rod q to the second lever m, is moved by the handle or other arrangement
in order to open the valve or cock, the fulcrum g of the second lever m is raised,
and the second lever m moves the first lever l, and so opens the valve v, and the
second lever m not being in one with the first lever l, if the handle or other
arrangement be quickly returned to its original position, the valve will still
remain open until a certain quantity of water or other fluid has been discharged;
but if the handle or other arrangement be held in the position to which it had been
moved to open the valve or cock, the first lever will, by reason of the weight w
attached to it, act on the second lever m, and the cylinder or tube arrangement
connected to the second lever m will allow the valve to be gradually closed.
By this apparatus therefore, the valve or cock will discharge immediately a
certain quantity of water or other fluid every time it is opened, but the valve or
cock cannot be held open beyond a certain time.
In the case of water closets, where no after flush of water is required, we can
dispense with the first named cylinder or tube c.
Having thus described the nature of our Invention, and the manner in which the
same may be used or carried into effect, we claim,―
The arrangement and combination of a valve or cock, and an apparatus to
regulate its opening and closing, substantially as described in the foregoing
Specification.
In witness whereof, we, the said Thomas Penn and Granville Sharp Ullathorne,
have hereunto set our hands and seals, this Nineteenth day of November,
in the year of our Lord One thousand eight hundred and seventy nine.
