IMPROVEMENTS IN WATER CLOSIT CISTERNS
Year: 1884

page_text: I, JAMES FAGAN Plumber High St Skipton in Craven in the County of York
do hereby declare the nature of my invention for IMPROVEMENTS IN WATER
CLOSIT CISTERNS to be as follows:-
This invention relates to certain improvements in Water closit Cisterns, and has
for its object the accomplishments of the following advantages-First been lined
with sheet lead in one piece and without soft solder joints it is not so liable to
injury by frost nor damage by water containing acids. Rolled sheet lead is superior
to cast as the latter is often porous and soon begins to waste water. The flush
valve opens downwards and at once charges the flush pipe with water and though
the chain be relieved the flush valve is kept open untill the cistern is empty.
If the chain pull be drawn down and kept down the ball tap does not continue
supplying cistern during the flushing but opens automaticalley when the cistern has
been completly emptied. It is superior to serpent pipe cisterns in that there is no
syphon lift of water to over come.
Wood cistern, A (Fig. 3) lined with sheet lead in one piece.
Ball, ârm, and ball tap B (Fig. 1).
Cast iron cross lever, C. (Fig. 4) to operate flush valve and ball tap.
Weighted end of cross lever D (Fig. 1).
Connecting link between ball tap arms,. and weighted end of cross lever, E
Fig. 1 the connection constitutes a water waste preventer it shuts the ball tap
when the flush valve is open.
Connecting rod between cross lever and flush valve F (Fig. 1) Its action is as
follows, when the cross lever is drawn down with the chain pull, the flush valve is
opened downwards, and the ball tap is closed, and kept closed untill the cistern is
empty, the water in the suction flush pipe M (Fig. 1) keep the flush valve open and
the ball tap closed untill the cistern is empty, although the chain pull be relieved.
When the suction is exhausted the weighted end of cross lever (D Fig. 1) closes the
valve and opens the ball tap simultaneiously.
Flush box G. (Fig. 1) made oval to allow flush valve to be easily removed, for the
renewal of india rubber washer.

I, JAMES FAGAN, of High Street, Skipton, in the West Riding of the County'
of York, Plumber do hereby declare the nature of my invention for IMPROVE-
MENTS IN WATER-CLOSET CISTERNS, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:
This invention relates to certain Improvements in Water-Closet Cisterns and
has for its object the accomplishment of the following advantages, viz: (1) the
flush-valve is so arranged that being once thrown open by pulling the chain, it
retains that position automatically till the cistern is quite empty; and (2) this
effect is further enhanced by the peculiar of the lever or cross-arm as modified in
this invention. I accomplish the above-named advantages in the following manner:
in the following description, which I illustrate by accompanying drawings, like
letters represent like parts in the respective drawings.
Figures 1 and 2 are longitudinal sections of the cistern, Figure 3 being a plan of
the same.
A is the cistern; B, B, B, is the ball-tap. C, C, is the lever or cross-arm,
suspended in the bearings O, O, G is the flush-box (of lead) to which is fixed a
flanged seating I of brass; the flush-valve H, of brass, being fitted with an india-
rubber washer which closes upon the said flanged seating; the said flush-box, flush-
valve and seating being oval in form, to permit the easier separation of the
respective parts for repairs &°. The peculiar arrangment and action of the flush-
valve in this invention is that it is suspended from the lever or cross-arm C, C, by
means of the connecting rod F, on the same of the bear- O, O as the pull chain J,
and that it has a downward motion in opening: the flush-valve being opened the
flush-pipe M becomes charged with water, causing atmospheric pressure to play
upon the upper surface of the flush-valve, which continues till the cistern becomes
completely exhausted. In the peculiar form of lever or cross-arm, C, C, adopted
in this invention, the axle is in part removed to permit the insertion of a rib R,
upon which a weight P, fitted with a pulley, is free to move along its entire length.
The action of the lever or cross-arm is that when depressed, as in Figure 2, the
weight P, takes the position there shown, near the connecting rod F, thus aiding
in keeping the flush-valve open during the emptying of the cistern; upon the
closing of flush-valve, by means of the weighted end D of the lever, the weight P
returns to the end D of the lever, thus rendering the flush-valve more secure
against internal pressure. E is a link, attached to lever C, C, which serves to hold
the ball tap closed during the emptying of the cistern, the ball being free to rise
and fulfill its normal purpose of closing the inlet K, when the flush-valve is closed.
Lis the waste outlet,

page_text: 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 the construction of Water-Closet Cisterns in which
(1) The flush-valve is so arranged as to ensure the immediate emptying of cistern
without a sustained pull of the chain attached thereto, thus relieving the user
from attention at once; and
(2) The lever or cross-arm is so modified in construction as to further enhance
the effect accomplished by the said arrangement of the flush-valve. The whole
being substantially arranged and ascertained as described, and as illustrated by the
accompanying drawings.
