Improvements in Flushing Cisterns.
-―
GEORGE NELSON LEIGHTON (Senior) Kelsick House Ambleside, Westmore-
land Plumber, do hereby declare the nature of this invention to be as follows:-
This invention relates to a mechanical contrivance by means of which water is
admitted to the flushing cistern only when immediately required for flushing the
closet, and is automatically discharged whenever a sufficient quantity has been
admitted, thus entirely obviating the effects of frost on water used for this
purpose. It is practically silent in its operation, and consists of the several parts
shown on the accompanying drawing and referred to in the following Specification,
viz. A tube A fixed in the cistern, within which tube works a balance catch
tube B which is raised when the handle C is pulled, simultaneously lifting the
valve tap D-catch E then resting upon the edge of the outer tube A.. At the
same time the discharge valve F is closed by the action of crank G attached to the
balance catch tube B by a connecting rod H, the water accumulating in the cistern
ntil the ball regulator I is sufficiently moved to press back the catch E, when the
discharge instantly takes place, the service pipe K being at the
exhausted by the automatic action of valve L shown in the enlarged section.

COMPLETE SPECIFICATION.
Improvements in Flushing Cisterns.
I, GEORGE NELSON LEIGHTON Senr., of Kelsick House, Ambleside, in the
County of Westmoreland, Plumber, 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 :-
This invention relates to a mechanical contrivance by means of which water is
admitted to the flushing cistern only when immediately required for flushing the
closet, the arrrangement being such that the water admitted to the flushing cistern
as required from time to time is automatically discharged therefrom whenever a
sufficient quantity has been admitted, that is to say when the water level has
attained a certain height in the cistern, thus entirely preventing the action of frost
on water used for this purpose as in the ordinary methods.
The apparatus I employ is practically silent in its operation, and consists of the
several parts shown on the accompanying drawing and referred to in the following
description, vis. :-A tube A is fixed in the cistern, (by being screwed into the
bottom thereof) within which tube is arranged a weighted catch tube B preferably
rectangular in cross section and having pivoted pendulums (Fig. 2) catch E and P,
the catch tube B being raised when the ordinary pull down handle C is pulled
downwardly. Simultaneously a throttle valve F is closed by the action of the
slotted lever G connected to the balance catch tube B by the rod H. The
apparatus then assuming the position indicated by broken lines. The action of
the lever S will thereupon impart an upward movement to the rod H. allowing
the catch E to move outwardly and rest upon the upper edge of the tube A thus
sustaining in its raised position the catch tube B. The catch P being drawn into
tube B by the said upward movement, prevents lever S staying the downward
movement of catch tube B when held up, and will also open by means of weighted
slotted lever N. the valve tap D thus allowing the water supply to pass along the

page_text: service pipe K into the cistern O until the water level has risen so as to lift the
float ball I sufficiently high to cause the extremity of the adjustable screw M to
press against the catch E & release the catch tube B which will thereupon drop to
the position shewn in solid lines thus again closing the valve D & opening the
valve F and so allowing the contents of the cistern to be entirely discharged and
thereby performing the flushing operation. The scatterers L L'as shown in the
drawing of basin are placed within about half an inch of the water line, so
effectually preventing the occurrence of practically any noise from such discharge.
Having now particularly described and ascertained the nature of my said inven-
tion and the manner of carrying it into practical effect I declare that what
I claim is: :-
1. The combination of the tube A catch tube B and catches E and P with the
Hoat ball I and the adjustable screw M arranged and operating substantially as
herein before described and shown in the drawings for the purpose specified.
II. The combination of the apparatus set forth in the preceding claim I of the
connecting rod H levers N and G valves D and F pull down lever S and service
pipe K arranged and operating substantially as hereinbefore described and shown
in the drawings for the purpose set forth.

III. In combination with the outlet or discharge end of the flushing pipe of a
water closet the use or employment of "scatterers such as L L arranged
substantally as hereinbefore described and shown in the drawings for the purpose
set forth.
