Improvements in Flushing Cisterns, and Details connected therewith.
I, PHILIP WINN of Granville Street Birmingham in the County of
Warwick, Manufacturer do hereby declare the nature of this invention to be as
follows
In syphon cisterns actuated by means of a piston contained in a cylinder the hole
in the top of the cylinder through which the cistern rod passes being frequently
required of an excessive diameter leaving a considerable clearance between the rod
and the edge of the hole, and this space being inconvenient on account of the water
escaping too freely and allowing air to enter, and the devices in the shape of stuffing
boxes or rubber washers which have hitherto been employed being unsatisfactory
through various reasons I provide a perfectly loose flange or ring of brass or
suitable hard material which while perfectly free to move on the rod and also to
move laterally on the face of the cylinder top, yet prevents an undue quantity of
water passing through the clearance between the rod and the cylinder top, or the
flange may be in one piece with the rod, arranged in a suitable position, it being
sometimes inconvenient to fix syphon cisterns having their pull or handle on the
one hand when it would be better if they were on the reverse hand, I arrange in
connection with syphon cisterns that the internal fittings shall be so arranged that
they can be reversed from right hand to left hand, and that the levers which actuate
the internal fittings shall be of such a description that they shall fit and work truly
in the bearings I provide for them towards either end of the cistern shell, the
bearings when not in use being hidden or otherwise made unobjectionable by means
of the cistern cover or other suitable means. The attachment of the cylinders to
the other internal fittings of syphon cisterns being frequently a cause of trouble, I
provide a cylinder cover having a return flange or socket into which the cylinder
foosely fits and attach the latter to the former by means of suitably arranged brass
clips depending for their attachment to the cylinder mainly upon pegs which are
inserted through the same and rivetted in position. The upper end of these clips
is passed through suitable snugs on the cylinder cover and made fast. The cylinder
cover may be bored in order to ensure a true fit with the cylinder, or a sufficiently
satisfactory joint may be made with lead or other material.
The noise of the water rushing into flushing cisterns is considered as objectionable
by some persons, and the usual arrangement of a silencing pipe from the mouth of the
ball cock being clumsy and expensive, I arrange the ball cock of a suitable form and
seat it upon the upper end of a cavity or channel cast along and down the side of
the cistern by means of which the water enters at the bottom without much noise,
and the necessity of attaching a separate pipe is obviated.
The cost of carriage being considerably increased in the instance of flushing
cisterns by account of the form in which they are of necessity made, I provide and
form them according to my invention of separate pieces, the sides bottom and ends
being in different pieces and intended to be put together and made up thereby into
complete cisterns at their destination by means of the suitable connection I provide
for this purpoве.

I PHILIP WINN of Granville Street, Birmingham in the County of Warwick,
Manufacturer, 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 :-
My invention has for its object improvements in syphon cisterns, particularly the
details connected therewith, which will be more fully explained with reference to
the following drawings-
Figure 1 is a longitudinal section shewing the internal fittings of a syphon cistern,
and
Figure 2 is a plan of same with cover removed.
Figure 3 is a section of a piston syphon shewing my loose flange or ring.
Figure 4 is a front elevation of Figure 3 shewing the attachment of cylinder.
Figure 5 is a front elevation of a syphon cistern shell made in separate pieces,
and
Figure 6 is an inverted plan of same.
Referring to Figures 1 & 2, it will be seen that I arrange in connection with
syphon cisterns, that the internal fittings can be reversed from right hand to left
hand, it being sometimes inconvenient to fix syphon cisterns having their inlets and
overflows on one hand only, I form the lever A which actuates the internal fittings
of such a description that it shall fit and work truly in the bearings B provided
towards either end of the cistern shell, the bearings when not in use being hidden or
otherwise made unobjectionable by means of the cistern cover or other suitable
means. I also fix the syphon in the centre of the cistern and form thereon four
lugs or projections R containing rubber cushion S for supporting the bell in position
and further preventing noise. To alter the cistern from one hand to the other, it
is only necessary to remove the cover and reverse the fittings as shewn by dotted
lines at Figure 2.
In syphon cisterns actuated by means of a piston in a cylinder, the hole in the
top of the cylinder through which the piston rod passes being required of an
excessive diameter, leaving a considerable clearance between the rod and the edge
of the hole, and this space being inconvenient on account of water escaping too
freely and allowing air to enter, and the devices in the shape of stuffing boxes, or
rubber washers which have hitherto been employed being unsatisfactory through
various reasons, I provide a perfectly loose flange or ring C shewn at Figure 3 of
brass or suitable hard material which while perfectly free to move on the rod D and
also to move laterally on the face of the cylinder top E yet prevents any undue
quantity of water passing through the clearance between the rod and the cylinder
top, or the flange may be in one piece with the rod arranged in a suitable position.
The attachment of cylinders to the other internal fittings of syphon cisterns being
frequently a cause of trouble, I provide a cylinder cover having a return flange or
socket F, Figure 4, into which the cylinder G loosely fits and attach the latter to
the former by means of suitably arranged brass clips H depending for their
attachment to the cylinder G mainly upon pegs inserted through the same and
rivetted in position. The upper ends of these clips are secured to suitable snugs J
on the cylinder cover E. The cylinder cover may be bored in order to ensure a
true fit with the cylinder, or a sufficiently satisfactory.joint may be made with lead
or other material.
The noise of the water rushing into flushing cisterns is considered an objection by
some persons, and the usual arrangement of a silencing pipe from the mouth of the
ball cock being clumsy and expensive, I arrange the ball cock K of a suitable form
and seat it upon the upper end of a cavity or channel M shewn clearly in
Figures 1 & 2 and which effectually prevents the rushing noise before mentioned.

page_text: The cost of carriage being considerably increased in the instance of flushing
cisterns on account of the form in which they are of necessity made, I provide and
form them according to my invention of separate pieces shewn at Figures 5 & 6 the
sides bottom and ends being in different pieces and intended to be put together and
made up thereby into complete cisterns at their destination by means of suitable
connections N provided for this purpose.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is-
1st. The details of syphon cisterns and details connected therewith substantially
as and for the purpose herein set forth and shewn upon the drawings.
2nd. The arrangement of internal reversible fittings substantially as herein set
forth.
3rd. The arrangement of loose flange, or ring on piston rod of syphon;
substantially as herein set forth.
4th. The attachment of cylinders to syphon cisterns substantially as herein set
forth.
5th. The construction of syphon cisterns of separate pieces substantially as and
for the purpose herein set forth.
6th. The combination of one or more of the said fittings substantially as and for
the purpose herein set forth and described.
Dated this 18th day of July 1894.
