I, ALEXANDER ALLAN, of 22 Marchmont Road, Edinburgh, in the County of
Mid Lothian, North Britain, Sanitary Plumber, do hereby declare the nature of
my said invention for "IMPROVEMENTS IN WATER SUPPLY APPARATUS FOR WATER-
CLOSETS," and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement, that is to say :-
My said Invention has for its object to improve and simplify the construction of
water supply apparatus for waterclosets.
In carrying out my Invention I use a cistern of a size suitable for containing the
quantity of water to be used at each flushing of the water closet, this cistern being
supplied in the usual way by a valve or stopcock worked by a ball float and lever.
The water is delivered from the cistern through a siphon pipe which when once
started delivers all the water in the cistern down to the bottom of the short leg of
the siphon. The distinguishing feature of my Invention is a simple, convenient,
and inexpensive device for starting the siphon, and consists in the connection of
the wire which is drawn down when the watercloset handle is pulled or raised to
the ball-float lever. The depression of the ball float by the wire causes the level
of the water to be raised above the top bend of the siphon and the water
immediately passes off by the siphon and downlet pipe to the watercloset.
The figure on the accompanying sheet of explanatory drawings is a vertical
section of a watercloset cistern as arranged according to my Invention. The water
is supplied to the cistern by a valve, A, worked by a lever, B, to which a ball
float, C, is fixed. The water is delivered from the cistern by a siphon, D, and
downlet pipe, E, which are by preference of large size so that the whole of the
water may be delivered quickly. The siphon, D, stands inside of the cistern,
through the bottom of which it is connected to the downlet pipe, E. The float
lever, B, has connected to it the wire, G, which is pulled down by the ordinary
mechanism of the watercloset when the handle is raised; and as in this example
the wire, G, is connected to the lever, B, between the float, C, and the valve, A, a
tube, H, is fixed in the bottom of the cistern to form a direct passage for the wire
up through the water. The wire, G, or a cord or chain may be arranged to act on
the float lever, B, in any convenient way; thus, if the lever, B, is extended beyond
the float, C, and so as to project over the end of the cistern, the wire may be
connected to its end without having to pass through a tube,

page_text: The siphon, D, acts as an overflow outlet to the cistern, but a separate overflow
outlet may be provided if desired.
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 mode of causing the delivery of water from a watercloset cistern fitted with
a siphon by depressing the ball float of the supply valve substantially as herein-
before described.
