Improvements in Apparatus in Combination with Water Waste
Preventers.
ALFRED ROBINSON 38 Great Smith Street Westminster in the county of
Middlesex, Sanitary Engineer do hereby declare the nature of this invention to be
as follows:
The object of my invention is to construct a simple apparatus in combination with
water waste preventors which will both discharge and refill itself by one downward
motion of the lever and can be operated in several ways, either by hand, or by an
automatic moveable seat action, a door action or by the action of unlocking of a
door.
In order to carry out my invention, I construct a cistern with an outlet at the
bottom. Inside the cistern in connection with the outlet is a valve with a syphon
attached, and from the outlet a pipe of less diameter than the valve which leads to
the pan or place to be flushed.
Above the syphon projecting from a pivoted spindle which same rotates between 'a
bracket fixed on top of cistern, I use a lever or quadrant with an extended arm on
each end or side, one arm running over the top of the cistern to which a chain wire
or rod is attached, and to the other arm a counterweight. I make in the quadrant a
slot, the top of the slot being widened to form a ledge or rest, and beyond the said
slot are two pins or guides, the use of which 1 will explain hereafter.
The quadrant and syphon are coupled together by means of a link, one end of this
link passes through an eye provided on the top of the syphon, and the other end
through the slot in the quadrant. The sides of the link are extended open and carried
beyond the top of the quadrant and allowed to pass between the two pins or guides
before mentioned.
When the apparatus is to be worked by hand, the one arm of quadrant is raised
and the weighted arm is lowered resting on a stop formed in the bracket. Whilst the
extended arms of quadrant are in this position the top part of the 'link connecting the
syphon with the quadrant is above the ledge or rest formed at the top of the slot and
kept over the top of the said ledge or rest by one of the pins or guides on the quadrant
as before mentioned. By pulling the rod or chain the quadrant partly rotates at the
same time raising the syphon and valve by means of the link resting on the ledge at
the top of the slot; but before the lever is quite pulled down the pin at the other side
of the link pushes the said link off the ledge which same then drops down the
slot.
In this manner the valve cannot be held open by holding the chain down, but falls
again by its own weight; thus when the syphon is being raised and before it can drop
again, sufficient water passes the valve to draw it over the syphon which runs until
the cistern is empty and immediately fills again by the ball valve in the usual way.
On releasing the chain or rod the weighted arm of quadrant falls and throws the
connecting link on the ledge of the slot by means of one of the pins on quadrant.
In order to work it by a moveable seat the chain or rod instead of hanging loose as
in the former, is held down by a weight attached to a pivoted lever under the seat.
The front of the said lever holds the seat up. When the weight of a body is on the
seat it presses the front of the aforesaid lever down and throws the weighted end.up,
thus slackening the chain or rod and by this means pushes the link on the ledge of the
slot in the quadrant; the weight of the body being taken off the seat the weighted
end of lever falls pulling the chain or rod with it and from this point operating the
apparatus as above. I sometimes work this with a foot-board in a similar way.

COMPLETE SPECIFICATION.
"Improvements in Apparatus in Combination with Water Waste
Preventers.
I, ALFRED ROBINSON, of 38 Great Smith Street, Westminster, in the County of
London, "Sanitary Engineer" do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
.tained in and by the following statement:-
The object of my invention is to construct a simple apparatus in combination with
water waste proventers which will both discharge and refill itself by one downward
motion of the lever and can be operated in several ways, either by hand or by an
automatic moveable seat action, a door action, or by the action of unlocking of a
door.
And in order that my Invention
describe the accompanying drawings thereof, reference being had to letters and figures
may be thoroughly understood, I now proceed to
marked thereon.
Figure 1 represents a section of the cistern N on line a, b, of figure 2, describing
the side view of the apparatus constituting my invention.
Figure 2 is the top view of the apparatus and cistern, with the ball valve S and the
⚫overflow V.
Figure 3 denotes the end elevation of the cistern on which the apparatus is
attached.
In order to carry out my invention, I construct a cistern N, with an outlet N¹ at
the bottom. Inside the cistern N in connection with the outlet is a valve with a
syphon O, attached, which works on guide rods P by the rings Qfixed on the syphon,
and R is a key to prevent the syphon from being removed; and from the outlet a pipe
is connected of less diameter than the valve which leads to the pan or place to be
flushed. Above the syphon is the arm A and quadrant (, projecting from a pivoted
spindle I which rotates between a bracket L fixed on to the cistern at M. I use a
lever C or a quadrant with an extended arm on each end or side, one arm A running
over the top of cistern to which a chain, wire or rod A¹ is attached, and to the other
arm a counterweight B. I make in the quadrant a slot II, the top of the slot being
widened to form a ledge or rest, and beyond the said slot are two pins or guides F,
the use of which I will explain hereafter.
The quadrant C and syphon O are coupled together by means of a link E, one end
of this link passes through an eye provided on the top of syphon O and the other end
through the slot in the quadrant at K. The sides of the link E are extended open, and
carried beyond the top of quadrant C and allowed to pass between the two pins or
guides F before mentioned.
When the apparatus is to be worked by hand, the one arm A of quadrant is raised
and the weighted arm B is lowered resting on a stop J, formed in the bracket L,
whilst the extended arm of quadrant or lever is in this position the top part of the
link E connecting the syphon with the quadrant is above the ledge or rest formed at
the top of the slot in the quadrant C, and kept over the top of the ledge by one of
the pins or guides F, on the quadrant as in figure 1.
By pulling the rod or chain A¹ the quadrant (partly rotates, at the same time
raising the syphon valve O, by means of the link resting on the ledge at the top of 5
the slot (indicated by dotted lines in figure 1,) but before the lever is quite pulled
down the pin F at the other side of the link E. pushes the said link off the ledge
which same:drops down the slot H. In this manner the valve cannot be held open

page_text: by holding the chain down but falls again by its own weight; thus, when the syphon
is being raised and before it can drop again, sufficient water passes the valve to draw
the water over the syphon which runs until the cistern is empty and immediately fills
again by the ball valve S in the usual way. On releasing the chain or rod the weighted
arm of quadrant falls and throws the connecting link on the ledge of the slot by means
of one of the pins F on quadrant as in figure 1.
In order to work the apparatus by a moveable seat the chain or rod A¹ instead of
hanging loose as in the former, is held down by a weight or spring attached to a
pivoted lever under the seat. The front of the said lever holds the seat up when the
weight of a body is on the scat it presses the front of the aforesaid lever down, and
throws the weighted end up thus slackening the chain or rod A' and by this means
pushes the link E on the ledge of slot H in the quadrant; the weight of the body
being taken off the sent the weighted end of lever falls pulling the chain or rod A¹
with it and from this point operating the apparatus as above described.
I sometimes work this with a foot-board in a similar way. If preferable I can
work my invention by the opening of a door by means of suitable connections
such as pulleys and quadrants, or other mechanism, and also by the action of
withdrawing a bolt or the unlocking of a door.
Having now particularly described and ascertained the nature of my said Inven-
tion, and in what manner the same is to be performed, I declare that what
I claim is
First: The combination of the apparatus to be fixed to a water waste preventer,
which will both discharge and refill itself by one downward motion of the lever
operated either by hand, or by an automatic moveable seat action, a door action,
or by the action of a bolt on unlocking of a door, substantially as herein described
and according to the accompanying drawings.
Secondly: The combination of the mechanism of the lever or quadrant C pivoted
to the bracket L, and the links E connected to the syphon and the slot H, and
the guide pins F to work the apparatus when the arin A is pulled down by the
chain A', substantially as herein described and according to the accompanying
drawings.
Thirdly The particular shape and mode of connecting the apparatus to at
syphon of water waste preventers as herein described and according to figures 1,
2, and 3.
