PROVISIONAL SPECIFICATION.
Improvements in or relating to Syphon Flushing Cisterns.
I, JOSEPH WEST, 289, Shalesmoor, City of Sheffield, Plumber, do hereby declare
the nature of my invention to be as follows:-
My invention relates more particularly to the construction of the cylinder
used for charging the syphon of flushing cisterns.
The invention may be applied to either vertically or horizontally fixed cylinders,
but I prefer to arrange the cylinder horizontally in the bottom of the cistern.
In carrying out my invention I propose to construct the inlet for the water to
the cylinder and the syphon, at the back end of the cylinder, but in such a
manner that when the water is forced by the piston out of the cylinder it will
pass into and charge the syphon instead of being forced out of the said inlet,
and this action is obtained without the use of valves or other moving parts either
connected with the piston or otherwise.
I attach to the back end of the cylinder, and to the short leg of the syphon
pipe, an elbow piece or bend, the interior waterway of which, leads directly to
the short leg of the syphon, and just beyond the curve of the bend I provide a
lateral opening or mouth communicating with the suction pipe, which is econo-
mically and preferably made in one piece with the said elbow or bend, and may
terminate at any desired distance from the bottom of the cistern.
The outer configuration of the elbow or bend may be varied, but the con-
nected waterways must have the same relative positions as before described.
The piston is operated by the usual cranks and pull cord or chain.

Improvements in or relating to Syphon Flusning Cisterns.
I, JOSEPH WEST, 289, Shalesmoor, City of Sheffield, 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:
-
My invention relates more particularly to the construction of the cylinder and
its adjacent parts, used for charging the syphon of flushing cisterns.
My invention may be applied either to cylinders when fixed vertically or hori-
zontally but I prefer to arrange the cylinder horizontally on the bottom of the
cistern

page_text: The accompanying drawings illustrate my invention as carried out in the way
I prefer.
Fig. 1, is an elevation in section of a cylinder constructed according to my
invention.
Fig. 2, a similar elevation of a modification.
Fig. 3, plan of same.
Referring to the drawings, C is the cylinder, P is the piston, E the elbow,
B the bell, and S is a portion of the syphon pipe.
In carrying out my invention as shown in Fig. 1, I construct the inlet for the
passage of the water to the cylinder C, and also to the syphon S, in the form of
a bell B, having a large opening near the bottom or floor of the tank or cistern F,
and a top opening to which I connect the short leg of the syphon S; there is also
a side opening communicating through the elbow or bend E, with the back end
of the cylinder C.
The cylinder consists of a short piece of straight pipe either screwed into the
flange A, of the bell B, or otherwise affixed thereto; it is provided with a piston P,
fitting loosely therein, the piston rod R, is connected with the usual crank over-
head and pull chain or any other suitable means for operating it.
The elbow or bend E, is curved upwards so as to direct the stream of water
when forced out of the cylinder by the action of the piston, into the syphon
pipe S, in order to charge the syphon.
Figs. 2 and 3, represent a modification in the form of the inlet, in this case I
dispense with the bell shape and use an oblong opening I, but the elbow or
bend E. the cylinder C, and piston P, are the same as before described.
My object is to simplify the mechanism of such apparatus, and to dispense
with valves and such like moving parts, and I wish it to be understood that I
am aware that cylinders and pistons with valves have been used for this purpose.
and therefore I do not claim such means broadly, but
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:-
-
1-For use in a syphon flushing cistern, the valveless combination of a cylin-
der C, with piston P. and a bend E at the end of the cylinder having its outlet
facing the mouth of the syphon S, and a bellshaped inlet B, open to the cistern,
and surrounding the said bend as herein before described and shown in Fig. 1, of
the drawings.
2-For use in a syphon flushing cistern, the valveless combination of a cylin-
der C, and piston P, with a curved outlet E, having its mouth facing the entrance
into the syphon S, and an inlet I, of any desired form open to the cistern and
to the syphon as hereinbefore described and shown.
