Improvements in Sanitary Flushing Apparatus.
I GEORGE EDMUND ARNOLD of Arnside Road West Marina in the Parish of
St. Leonard in the County of Sussex Gentleman do hereby declare the nature
of this invention to be as follows:-
My invention relates to Improvements in Sanitary Flushing Apparatus.
In carrying out my invention I provide a small cistern preferably of metal suitably
fitted with a ball cock for regulating the supply of water, the arm of which is
hereinafter referred to as lever B. Into the bottom of the cistern is fitted a pipe for
conveying the water to the closet-pan. This pipe is provided preferably at the end
nearest to the closet pan with a valve whereby the water is prevented from leaving the
cistern except when the apparatus is brought into action. When the aforesaid pipe is
of any considerable length I also place at the upper end of it a check-valve to prevent
the lower valve from closing too suddenly.
Attached to the aforesaid valve or valves is a wire or chain connected with a lever
hereinafter referred to as lever A which is attached to the cistern and is so arranged
that one arm may be within the cistern, the other arm wholly or partly outside the
cistern. To the arm of lever A outside the cistern is attached a suitable chain or
wire with a ring or pull for the convenient working of this lever. Within the cistern
is placed a swinging pawl having a notch or projection formed thereon and so placed
that when the outer arm of lever A is depressed and the inner arm with the valve or
valves attached consequently raised, it is thereby detained and the aforesaid valve or
valves are held open. The before mentioned lever B is so arranged that when it has
descended the requisite distance it engages with a part of the pawl and releases
lever A. The action is as follows-Upon pulling down the outer arm of lever A the
inner arın is raised and engages with the pawl at the same time lifting the retaining
valve or valves and thus allowing the water in the cistern to flow down the pipe. As
the water recedes from the cistern the ball and lever B fall with it and the
lever B continuing to descend engages with the pawl and releases lever A
which, being no longer upheld, drops, and thus effects the closing of the aforesaid
valve or valves. I sometimes modify the construction of my apparatus by placing the
pawl or detent so as to engage with the outer arm of lever A or with a supplementary
arm thereof.
When the apparatus is required to act also as a water waste preventer I use a short
lever, hereinafter referred to as lever fitted to the supply cock and connected to the
inner arm of lever A by a link or chain of such a length as to prevent lever C from
falling during such time as lever A is raised. To lever I also attach with a hinge
the lever B with ball affixed. The action is as follows-Upon pulling down the outer
arm of lever A and raising the inner arm thereof as aforesaid, the link or chain
connecting the inner arm to lever maintains the latter in position and thus prevents
the supply cock from opening. The lever B with ball attached falls with the water
and engaging with the pawl releases the inner arm of lever A, which, being no longer
upheld drops and in so doing in its turn permits lever C to drop and open the supply
cock attached thereto. As the cistern fills lever B with ball affixed rises with
the water and carrying up with it lever C gradually closes the supply cock.

Improvements in Sanitary Flushing Apparatus.
GEORGE EDMUND ARNOLD Arnside Road St. Leonards on Sea Sussex Gentleman
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 Improvements in Sanitary Flushing Apparatus and
to carry out the said invention I provide a suitable cistern fitted with a ball cock and
lever for regulating the supply of water or other liquid. In the bottom of the said
cistern I fit a pipe for conveying the water in the cistern to the closet. This pipe is
provided with a suitable valve as now used, and this valve may be fitted at either end
of the said pipe, and prevents the water from being discharged from out of the cistern,
until brought into action. When the said discharge pipe is of any great length
I provide a check valve at the cistern end thereof. I connect one end of a chain or
wire to the said valve or valves & the other end of the said chain or wire I secure to.
a suitable lever pivotted to the cistern. One end of this said lever is within the
cistern and the other end of same projects out of the cistern and is connected with a
chain forming the pull. Within the cistern a hanging or swinging pawl having
a notch or projection formed thereon for engaging with the end of the said lever to
which the valve or valves is or are connected. When the "pull" is depressed, the
pull lever is raised and is detained by catching in the said notch on the said pawl. The
ball lever contains à suitable projection so that when it has descended a certain
distance the said projection thereon comes in contact with the swinging pawl, pushes
same forward and releases the pull lever..
Referring to the accompanying drawings. Fig. 1 shows side elevation of my
invention partly in section. A is an ordinary cistern. B. the inlet for water supply.
C the outlet to closet. D. the ball cock & lever secured at D'. D² the projecting
piece thereon. E the pull lever one end of which projects outside the cistern and is
connected with the pull chain F, and the other end within the cistern is connected
with the said valves G by means of chain or wire H. I is the swinging pawl pivotted
at I, and having a notch or catch thereon I which engages with lever E.
The action of the parts is as follows. Upon pulling down the pull F the part of the
lever E. within the cistern is raised and engages with the pawi I at I² which action
opens the valves and thus letting out the water; as the water recedes from the cistern
so the ball and lever D fall until the projection D2 comes in contact with the
swinging pawl I and releases the lever E and enables the valves again to be
closed.
I sometimes modify the construction of my apparatus by placing the pawl so as to
engage with the outer arm of lever E. or with a supplementary arm thereof.
When the apparatus is required to act as a water waste preventer 1 use a short
lever K fitted to the supply cock and connected with the inner arm of lever E, or it
may rest thereon so as when lever E is raised it will also raise lever K and shut off
the supply of water at B. When I employ lever K I find it convenient to hinge
lever D to same at K¹ instead of to the ball cock. The lever K when employed
is regulated by the action of lever E and either lets on or shuts off the supply.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is
(1) The combined arrangement and action of the apparatus as shewn in the annexed
drawings and substantially as described and for the purpose set forth.
(2) In an apparatus for flushing purposes the lever E, so arranged as to engage
with the swinging pawl 1' and which is automatically disengaged therefrom by means

page_text: of the ball cock lever having a projecting piece D2 thereon substantially as described
and shewn in the annexed drawings.
(3) In an apparatus for flushing purposes the lever K actuated by the lever E for
closing the supply valve substantially as described.
