WATER CLOSET CISTERN
Year: 1885

page_text: ANDREW KERR, 55 Canterbury St. Blackburn Lancashire, England, Pattern
Maker, do hereby declare the nature of my invention for WATER CLOSET CISTERN
to be as follows:
=
I first make a cistern of iron or other suitable material. Inside of same I place
a smaller vessel worked off two centres also two levers to operate on the same.
Also a pivot on small vessel to work the two levers. To the cistern I connect
town's or other water by means of a tap worked by a lever, from the small vessel.
The action is as follows: for seat action closets. To the movable seat is
fastened chain or rod connected above to lever, which when acted upon by persons
sitting upon the seat, drops down and relieves the smaller vessel, which then cants
over thereby opening the tap and admitting water. As soon as small vessel is full
it rights itself at the same time shutting off inlet as before. Immediately the
seat is relieved the small vessel goes down, & opens a valve in the same, thereby
discharging the whole of the water down.leaden or other pipe which is connected
from bottom of cistern to closet pot.
The superiority claimed for this cistern is, that it remains empty only when in
action. Thereby being proof against frost and a thorough waste preventer of
water. And that it is so adapted to be used for either pull or seat action.

page_text: ANDREW KERR, 55 Canterbury Street Blackburn, Lancashire, England, Pattern
Maker do hereby declare the nature of my invention for WATER CLOSET CISTERN
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
I first make a cistern A of iron or other suitable material. Inside of same
I place a smaller vessel B worked off two centres also two levers to operate on the
same, also a pivot on small vessel to work the two levers. To the cistern I connect
town's or other water, by means of a tap worked by lever D from the small vessel.
The action is as follows, for seat action closets. To the moveable seat is fastened
chain or rod connected above to lever C, which when acted upon by persons
sitting upon the seat, drops down & relieves the smaller vessel B, which then
cants over thereby opening the tap & admitting water: as soon as the vessel is full
it rights itself at the same time, shutting off inlet as before by raising lever D.
Immediately the seat is relieved the small vessel goes down and opens a valve E in
the same, thereby discharging the whole of the water down leaden or other pipe
which is connected from bottom of cistern to closet pot. The superiority claimed
for this cistern is that it remains empty, only when in action, thereby being proof
against frost, and a thorough waste preventer of water, and that it is so adapted
to be used for either pull or seat action.
A more detailed description of the action of cistern is as follows for seat action
closets. To the moveable seat is fastened the rod F, which rod is raised when a
person is in the act of sitting upon the closet, thus causing levers C & D to drop
down, and releive the small vessel B which then cants over, the function of
the hooked lever shewn in connection with pivot alongside of small vessel is to
prevent its canting too far, the weighted lever D (which is connected to C by
projecting piece cast on side, the lever C being underneath projecting piece, the
two levers consequently rise or fall together) then opens the inlet valve against
the pressure of the main, at the same time closing the valve E of small vessel, thus
allowing small vessel to become filled with water, as soon as it is full it rights
itself & raises the lever D thus allowing the pressure on the main to close the
inlet valve, and prevent a further supply of water, immediately the seat is releived
the rod F drops thus raising the levers C & D and opening the valve E in small
vessel, thus discharging the whole of the water down leaden or other pipe, which
is connected from bottom of cistern to closet pot, the small vessel remaining empty
of water until the act of sitting upon the seat is repeated.
I declare (after having now particularly described and ascertained the nature of
my said invention, and in what manner the same is to be performed) that what
I claim is
That with the above combinations, the cistern is empty, (only when in action)
thus being proof against frost, and also a thorough waste preventer of water, and
that it is so adapted to be used for either pull or seat action.
