I, GRANVILLE SHARP ULLATHORNE of 63 Queen Victoria Street, in the City
of London, Civil Engineer do hereby declare the nature of my invention for
IMPROVEMENTS IN APPARATUS AND VALVES FOR THE PREVENTION OF WASTE OF
WATER OR OTHER FLUID to be as follows:-
-
It is especially applicable to water closets, and consists of a main valve through
which the water or other fluid is to pass, and an arrangement for regulating the
opening and closing of such valve, the whole being preferably self contained on
one bedplate.
In my apparatus I make the handle or pull up, by means of which the main
water valve is opened and closed, to form, or be attached to, a piston rod, the
piston of which works in a main cylinder. The main cylinder is free to move up
and down in a slide, or slides, on an upright, or uprights, forming part of, or
attached to, the bedplate. I make the piston working in the main cylinder to be
loose on the piston rod, with a space between the piston and piston rod, and to be
carried between two discs forming part of, or attached to, the piston rod, which
discs are at a distance apart greater than the thickness of the piston. I make the
upper disc to be perforated; or I substitute for the upper diso a projection, or
projections from the piston rod, and I make a small hole in the lower disc, or
I make the piston to fit somewhat loose, in the main cylinder. I fill the main
cylinder with oil or other suitable fluid. The effect of the arrangement of piston
and discs described, is to cause the piston to act as a valve, not allowing the oil or
other suitable fluid in the main cylinder to pass on the up stroke of the piston
excepting very slowly.
I arrange a lever so that one end shall rest on the outside top of the main
cylinder, or on a connection therewith, and the other end shall open or close the
main water valve according as the cylinder is raised or lowered. To this lever
I attach a weight so that, when free, it shall return to its original position and
close the main water valve; and I also attach it a regulating cylinder or other
suitable device, to prevent the main water valve closing suddenly.
In some cases I construct this regulating cylinder with piston and discs on the
piston rod, similar to those in the main cylinder already described, but with discs

page_text: and consequent action reversed, so that the piston can move only slowly on the
down stroke, thus preventing any sudden return of the lever actuating the main
water valve, to its original position.
The effect of the arrangement of this apparatus is, that when the handle and
therefore the piston is raised, it carries with it the main cylinder in consequence
of the action of the piston forming a valve, and therefore the end of the lever
resting on the main cylinder, or on a connection with it, is raised so that the main
water valve is opened, but if the handle be retained in its raised position, the oil
or other fluid inside the top of the main cylinder will be forced, in consequence of
the weight of, or on, the main cylinder, slowly from the top to the bottom of the
main cylinder through the small hole in the lower disc on the piston rod, or past
the piston as the case may be, so that the main cylinder will slowly fall to its
original position, and the main water valve will close. If the handle be now
lowered, the oil or other fluid inside the main cylinder will be rapidly forced from
the bottom to the top of the main cylinder through the perforations of the upper
disc, or, past the projection, or projections from the piston rod as the case may be,
so that no obstruction will be offered to the downward movement of the piston,
and its quick return to its original position.
"
"
In certain closets such as
pan closets
and "valve closets," the raising and
lowering of the handle has not only to open and close the main water valve, but
also to open and close the pan or valve of the closet. In these cases I arrange
that a projection or projections in connection with the cylinder, shall engage with
the usual lever to open and close the closet pan or valve. In order to secure a
discharge of water for a short time after the closet pan or valve shall be closed,
commonly called an "after flush," even when the handle is retained in its raised
position, I arrange, in some cases, that when the handle and consequently the
cylinder and the end of the lever shall be raised and the main water valve opened,
another lever or catch, pivoted on, or otherwise attached to the bedplate, or the
upright or uprights carrying the slides, shall retain the first named lever in its
position, but when the main cylinder shall fall to its original position, the catch
lever shall be forced back, and shall release the first named lever, so that the main
water valve will close, though not until after the closet pan or valve shall be
closed. In other cases to obtain an "after flush I arrange that the projection or
projections in connection with the main cylinder shall be of such height that the
closet pan or valve shall close before the main water valve has closed.
"
I construct my main water valve of such form that it may withstand a high
pressure of water or other fluid, and I make it conical, or wedge shaped, bedding
on a similarly shaped seat, the water passing through from side to side, or I make
it in the form of a double valve conical shaped, bedding on a corresponding seat,
the water passing from top and bottom to a central discharge space, the pressure of
water, consequent on the larger area of one end of the double valve, assisting in
keeping the valve tight.

DESCRIPTION OF THE DRAWINGS.
Fig. 1 represents an end view of my apparatus.
Fig. 2 represents a side view of my apparatus with portions shewn in section.
Fig. 3 represents a cross section through the main valve.
In my apparatus I make the handle or pull up a by means of which the main
water valve k is opened and closed to form, or be attached to, a piston rod b, the
piston d of which, shewn in section in Fig. 2, works in a main cylinder c also
shewn in section in Fig. 2. The cylinder c or a connection with it, is free to
move up and down in a slide or slides 8 & on an upright or uprights e e, forming
part of, or attached to, the bedplate f. I make the piston d working in the
main cylinder c to be loose on the piston rod b, with a space between the piston
and piston rod, and to be carried between two discs g g₁ forming part of, or
attached to, the piston rod b, which discs g g₁ are at a distance apart greater than
the thickness of the piston, and I make the upper disc g to be perforated, or
I substitute for the upper disc g a projection or projections from the piston rod b,
and I make a small hole in the lower disc g₁, or I make the piston d to fit some-
what loose in the main cylinder c I fill the main cylinder c with oil or other
suitable fluid.
The effect of the arrangement of piston d and discs gg, described, is to cause the
piston to act as a valve, not allowing the oil or other suitable fluid in the main
cylinder c to pass on the up stroke of the piston excepting very slowly.
I arrange a lever h so that one end shall rest on the outside top of the main
cylinder cor on a connection i with the main cylinder c, and the other end shall
open or close the main water valve k by means of the spindle p attached to it,
according as the cylinder c is raised or lowered. To this lever h, if not of sufficient

page_text: "
weight itself, I attach a weight, so that when free, it shall return to its original
position and close the main water valve k, and I also attach to it a regulating
cylinder c₁ shewn in section in Fig. 2, or other suitable device to prevent the main
water valve closing suddenly. In some cases I construct this regulating cylinder &
with piston d, and discs 9, 9, on the piston rod b₁ similar to those in the main
cylinder c already described, but with discs and consequent action reversed, so that
the piston d can move only slowly on the down stroke, thus preventing any
sudden return of the lever h actuating the main water valve k, to its original
position.
The effect of the arrangement of this apparatus is, that when the handle a and
therefore the piston d is raised, it carries with it the main cylinder c in consequence
of the action of the piston d forming a valve, and therefore the end of the lever h
resting on the main cylinder, or on a connection with it, is raised so that the
main valve k is opened, but if the handle a be retained in its raised position, the
oil or other fluid inside the top of the main cylinder c will be forced, in consequence
of the weight of or on the main cylinder c, slowly from the top to the bottom of
the main cylinder c through the small hole in the lower disc g₁, or past the piston
as the case may be, so that the main cylinder o will slowly fall to its original
position, and the main water valve k will close. If the handle a be now lowered,
the oil or other fluid inside the main cylinder c will be rapidly forced from the
bottom to the top of the main cylinder c through the perforations of the upper
disc g, or past the projection or projections from the piston rod as the case may be,
so that no obstruction will be offered to the downward movement of the piston d
and its quick return to its original position.
In certain closets such as " pan closets" and " valve closets," the raising and
lowering of the handle has not only to open and close the main water valve, but
also to open and close the pan or valve of the closet. In these cases I arrange that
a projection or projections ₁ in connection with the main cylinder c shall engage
with the usual lever to open and close the closet pan or valve.
In order to secure a discharge of water for a short time after the closet pan or
valve shall be closed, commonly called an "after flush," even when the handle is
retained in its raised position, I arrange, in some cases that when the handle a and
consequently the main cylinder c and the end of the lever h shall be raised, and
the main water valve k opened, another lever or catch m pivoted on, or other wise
attached to the bedplate or the upright e or uprights e e₁, shall retain the first
named lever h in its position, but when the main cylinder c shall fall to its original
position, the catch lever m shall be forced back by a projection n in connection
with the main cylinder c, and shall. release the first named lever h, so that the
main water valve k will close, though not until after the closet pan or valve shall
be closed. In other cases to obtain an "after flush," I arrange that the projection
or projections, in connection with the main cylinder c, shall be of such height
that the closet pan or valve shall close before the main water valve has closed.
I construct my main water valve of such form that it may withstand a high
pressure of water or other fluid, and I make it conical or wedge shaped as shewn
at k in Figs. and 3, bedding on a similarly shaped seat, the water passing through
from side to side, or I make it in the form of a double valve conical shaped,
bedding on a corresponding seat; the water passing from top and bottom to a
central discharge space, the pressure of water consequent on the larger area of one
end of the double valve assisting in keeping the valve tight,
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim is
1. The application to an apparatus for preventing the waste of water, of a loose
piston working on a piston rod in a cylinder substantially as described and set
forth in the accompanying drawings.
