IMPROVEMENTS IN SYPHON WATER WASTE PREVENTER CISTERNS to be as follows:
Year: 1885

page_text: I, EDWIN ANDREW REYNOLDS, of 181 High Holborn, London in the County
of Middlesex, Sanitary Engineer, do hereby declare the nature of my invention
for "IMPROVEMENTS IN SYPHON WATER WASTE PREVENTER CISTERNS to be as
follows:-
"
My Invention relates to a water waste preventer being a syphon of the annular
type in which by the depression of the lever a discharge of say Two Gallons more
or less takes place with great velocity and certainty. It is particularly adapted to
work with the "Wash Out" type of Closets but will give good results in con-
nection with "Hoppers" having inlets at the back.
I propose to use a starting lever the depression of which will cause a connecting
rod to act on a piston and force water lying in the piston cylinder and equal to the
capacity thereof through a port into an annular space round a cone.
The water being forced up the said annular space will descend in a funnel shaped
stream into the cone a partial vacuum will thus be created above the stream, and
the water contained in the annular space will rush up to fill it discharging also
into the cone and thus a syphon action will be set up the cone being connected
with lead pipe to the closet.
I provide this cistern with a Free Action Ball-valve.
To enable the water to rise equally in the annular space and cistern I bore a
small hole in the port or in any other convenient place.
I propose to make the outside casing to stand above the bottom of the cistern so
as to allow water to enter freely to syphon, I give it by preference a conical form
so that a small displacement in the cylinder will result in a rapid rise in the
annular space.
On the crown of the outer casing I propose to cast lugs to carry the lever, one
end of which will terminate with a counterpoise in the cistern, on the other will
hang the chain or pull.
The inner casing port and cylinder I propose to cast in one piece and to ensure
easy working and to avoid the expense of boring the cylinder I line it with lead
run in with sulpher.
I propose to make the piston watertight by means of a cup leather, this during
the downward stroke will be pressed firmly to the lining but in the upstroke it
will collapse and have little or no friction, thus requiring only a small counterpoise.

page_text: To insure that no air passes the cylinder during the discharge, which would stop
the action of syphon I propose to form a disc valve on the connecting rod of the
piston when the lever is depressed, this valve will seat itself on the "tarfed " edge
of the lead lining and will be kept in that position by the syphon action until
the cistern is empty.
I prefer the outer and inner casings as described, but I may do away with the
outer casing and form a small flap valve on the inner, this valve will be closed by
the depression of the lever and the water contained in the annular space will be
forced up as already described; the valve in time opening inwards by the influence
of the syphonic action, so that the whole of the water in the cistern passes to
the cone.

page_text: I EDWIN ANDREW REYNOLDS of 181 High Holborn London in the County of
Middlesex Sanitary Engineer do hereby declare the nature of my invention for
"IMPROVEMENTS IN SYPHON WATER WASTE PREVENTER CISTERNS" and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:―
My Invention relates to a Water Waste Preventer being a syphon of the
annular type in which by the depression of the lever a discharge of say Two
Gallons, more or less, takes place with great velocity and certainty.
"
It is particularly adapted to work with the Wash out" type of Closets but
will give good results in connection with "Hoppers" having straight arm inlets at
the back.
In my improved water waste preventer the depression of a starting lever causes
a connecting rod to act on a piston and force water lying in the piston cylinder
and equal to the capacity thereof through a port into an annular space round
a Cone.
The water being forced up the said annular space will descend in a funnel
shaped stream into the Cone, a partial vacuum will thus be created above the
stream, and the water contained in the annular space will rush up to fill it,
discharging also into the cone, and thus a syphon action will be set up, the.cone
being connected with lead pipe to the closet.
On the accompanying sheet of Drawings.
Figure 1 is a sectional elevation of a Water waste preventer Cistern embodying
my Invention and
Figures 2, 3 & 4 are similar views showing modifications of same; similar letters
of reference indicate similar parts in each of the Figures respectively.
Referring to Fig 1, A is a starting lever, the depression of which will cause the
connecting rod B, to act on the piston C, thereby forcing the water contained in
the piston cylinder D, port E, and the annular space F, up this annular space and
causing it to descend in a funnel shaped stream into the cone G.
A partial vacuum is thus formed, and the water contained in the annualar space H,
open to the Cistern at h will rush up to fill this vacuum discharging also into
cone G, and thus a syphon action will be set up; Cone G being connected by a
lead pipe to closet.
The usual Ball valve admits water into the Cistern, and to enable the water to
rise equally in the annular space F and cistern, I make a small hole in port E, or
any other convenient place.
I make the outside Casing I to stand above the bottom of cistern, so as to allow
water to enter freely to syphon. I give it by preference a conical form, so that
a small depression of the piston C, will result in a rapid rise of water in the
annular space F.
On the crown of the outer casing I may cast lugs, to carry the lever A, one end
of which will terminate in the counterpoise J, on the other will hang a chain or
pull, or I may carry the lever A in any convenient manner. I propose to cast in

page_text: '
one piece the inner casing, and piston cylinder, and to ensure easy working, and
to avoid the expense of boring cylinder, I may line it with lead pipe K run in
with sulphur.
If the piston is made water tight by a loose fitting cup leather, I propose to
employ a disc valve L, so arranged that when the lever is depressed, this disc
valve will seat itself on the edge of the lead lining, and will be kept there by
syphonic influence during the discharge of the Cistern.
Figure 2 Is a similar arrangement to that shown Fig 1, but in this case I dis-
pense with the outer casing I, the water passing to the annular space F, and
thence to the cone G, by an opening at M₁, and I prevent the water escaping
through this opening M when the piston is descending, by placing a shield N in
front of the opening; when the piston is depressed, the water striking the shield,
is forced upwards, driving with it the contents of the annular space F, over the
lip of the cone G, and so setting up-a syphon action, the contents of the tank
being drawn in through the opening M already described. The vertical height
from lip of cone, to water line in cistern, being less than in Fig 1, I propose to use
a loose fitting disc O, instead of a cup leather, as shewn in Fig 1.
Figures 3 and 4 show an arrangement differing from that Fig 2 only in that the..
water is admitted to Cone G, through flap valves P, P. In Fig 3 the valve P is
placed vertically, and in Fig 4 horizontally, these valves will be closed by the
depression of the lever A, and the water contained in the annular spaces F F will
be forced up as already described, the valves P, P, in time opening inwards by
the influence of the syphonic action, and the Contents of Cistern thus passing to
cone G.
"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 "
