PROVISIONAL SPECIFICATION.
Improvements in Flushing Cisterns.
I, SAMUEL BENJAMIN GOSLIN of the Crescent Foundry Cripplegate in the City of
London Engineer do hereby declare the nature of this invention to be as
follows:
According to this invention I close the outlet by a ball of less specific gravity than
water, so that it tends to float-The bottom of the cistern is inclined towards the
outlet so that when the cistern is empty the ball runs down to a seat there.
A rod actuated by a handle or pull is provided by which the ball can be pushed to
one side off the seat; when this has been done the ball floats and does not come to
its seat again until the cistern is empty or nearly so.
COMPLETE SPECIFICATION.
Improvements in Flushing Oisterns.
I, SAMUEL BENJAMIN GOSLIN, of the Crescent Foundry, Cripplegate, in the City
of London, Engineer, do hereby declare the nature of this invention and in what
manner the same is to be performed to be particularly described and ascertained in
and by the following statement :-
According to this invention I close the outlet by a hall of less specific gravity than
water, so that it tends to float. The bottom of the cistern is inclined towards the
outlet so that when the cistern is empty the ball runs down to a seat there.
A rod actuated by a handle or pulf is provided by which the ball can be pushed to
one side off the seat; when this has been done the ball floats and does not come to
its seat again until the cistern is empty or nearly so, or the apparatus may be
arranged so as to discharge the water automatically when the cistern is full.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a vertical longitudinal-section and Figure 2 is a plan partly in section
of the apparatus to be worked by hand.
A is the cistern, B is the ball which rests in a seat above the outlet C. D is a bell
crank lever pivotted at d. The lever D is moved by the forked arm E projecting
from the lever F pivotted at G to which is attached the cord or pull H.
When the
latter is pulled the lower arm of the lever D strikes against the ball and knocks it
from its seat when it floats to the surface of the water. The lever D is brought
back into its original position by its own weight and the lever F by the counter-
balance weight J. K is the ball cock by which the cistern is filled.
Figure 3 is a vertical longitudinal section and Figure 4 is a vertical transverse
section of the apparatus arranged to be worked automatically.
In this arrangement the ball B is pushed off its seat by the lever L which is
pivotted on the arm L' and having a weight M attached to its other end.
The lever L is actuated by the arm N also pivotted to L' which having a float N¹
attached to it rises with the water as it enters the cistern. When the latter is nearly
full the arm N comes into contact with stop O on the lever K and thereby upsets the
equilibrium of the lever K which turns on L' and its momentum with that of the
weight M is sufficient to displace the ball allowing the water to escape. The lever N
descends again as the water runs out and in so doing comes into contact with the

page_text: stop P and so brings the lever K back to its former position against the stop Q.
Owing to the inclined bottom of the cistern the ball B replaces itself on the seat C.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed 1 declare that what
I claim is :-
1. A flushing cistern having its outlet closed by a ball of less specific gravity than
the liquid to be discharged.
[. 2. The combination of a flushing cistern having its outlet closed by a ball of less
specific gravity than the liquid to be discharged with a lever for displacing the ball
substantially as described.
3. Flushing cisterns substantially as described and shown by the drawings..
