PROVISIONAL SPECIFICATION.
Improvements in and connected with Flushing Apparatus for
Cisterns, Tanks, and the like.
I, JAMES BARKER LEDGARD, of 12, Salisbury View, Armley, in the City
of Leeds, Engineer, do hereby declare the nature of this invention, to be as
follows:-
The object of my invention is to create a flush or unopposed passage of the fluid
without taking or passing such through the charging or displacer chamber by
causing the piston or displacer in the cylinder or charging chamber to create a
Buction or vacuum in the inlet and branch pipes, and thereby cause the fluid to pass
from the cistein or tank into the delivery pipe without passing through the said
cylinder or charging chamber into the branch pipe or syphon.
Also by means of the said brauch pipe to discharge the entue contents of the
Cistern or tank.
According to my invention I employ a cylinder which forms the charging
chamber fitted with a piston, displacer, or plunger. The said cylinder or charging
chamber may be arranged so that the piston or displacer works in a vertical,
horizontal, diagonal, or inclined direction
The cylinder or charging chamber is provided with holes, apertures, or valves
for allowing the ingress of water, or may be submerged within the cistern or
tank.
The cylinder or charging chamber is also provided with a holos or holes for
allowing the liquid contained in the said cylinder to subside with the liquid in the
cistern or tank without obstructing the Hush. The said cylinder or changing
chamber and piston, or displacer, may be so constructed as to form a liquid trapped
Joint.
The branch pipe of the syphon may be joined to the base of the cylinder, in this
case the piston or displacer is caused to act in a downward direction.
Also the inlet pipe Joins into or forms a part of the branch pipe and the syphon
connection to the delivery pipe for the flush The base of the cylinder is provided
with inlets, or apertures, or valves may be used, if preferred.
In some cases a valve may be fitted at the junction of the inlet pipc, brauch pipe,
and syphon.
Or in some cases the branch pipe may join into the top of the cylinder, and in
this case the piston or displacer works in an upward direction to close the branch
pipe when required.
The inlet and branch pipes are in this case made as one or joined into each other,
and the syphon is joined into them at or about their junction.
In some cases a valve aangement is used in connection with and preferably
underneath the branch or suction pipe, so that when the piston or displace closes
the branch pipe, or outlet pipe, the suction in the syphon lifts the valvo and causes
the water to flow through the syphon.
In some cases a valve may be used in connection with the suction pipe.
Tho piston or displacer may be loose or valves may be used in connection with it.
In some cases the inlet or suction pipe may be joined into or form a part of the
stand, or delivery pipe. The displacer or piston may be so ai ranged as to close
both or either ends of the charging chamber by employing discs or diap'.iagms

the piston rod or spindle, the branch or suction pipe in this case may be part
of or attached to the cylinder or charging chamber.

Improvements in and connected with Flushing Apparatus for
Cisterns, Tanks, and the like.
I, JAMES BARKER LEDGARD, of 12, Salisbury View, Armley, in the City
of Leeds, Engineer, do hereby declare the nature of this invention, and in what
manner the same 18 to be performed, to be particularly descubed and ascertained
in and by the following statement.—
The object of my invention is to create a flush or unopposed passage of the fluid
without taking or passing auch through the charging or displacer chamber by
causing the piston or displacer in the cylinder or charging chamber to create a
suction or vacuum in the inlet and branch pipes, and thereby cause the fluid to pass
from the cistern or tank into the delivery pipe without passing through (or by
modifications the flush may pass through) the said cylinder or charging chamber
into the branch pipe or syphon. Also by means of the said branch pipe to discharge
the entire contents of the cistern or tank.

Fig. 25, is a modification of piston or displacer.
In Figs. 17 to 26, and in Fig. 15 the flush is not carried through the charging
chamber or cylinder.
According to my invention I employ a cylinder A which forms the changing
chamber fitted with a piston, displacer, or plunger B.
The said cylinder or changing chamber A may be arranged so that the piston or
displace works in a vertical, (see Figs. 1 to 4) horizontal, see Fig. 5, and the
following ones, diagonal or inclined direction. The cylinder or charging chamber A
may be provided with holes o apertures C, and valves D are employed for allowing
the ingress of water Or the cylinder oi charging chamber may be submerged
within the cistein or tank. The cylinder or charging chamber A is also provided
with air holes E for allowing the liquid contained in the said cylinder A to
subside with the liquid in the cistern or tank A' without obstructing the flush.
The said cylinder or charging chamber A and piston or displacer B may be so
constructed as to form a liquid trapped joint such as shown with reference to
Figs. 1 to 4.

page_text: 18 a well formed in the bottom of cistern or the like for drawing off the whole
of the liquid in such container.
The branch pipe G of the syphon G' may be joined to the base of the cylinder A,
see Figs. 2 to 4, in this case the piston or displacer B is caused to act in a downward
direction. Also the inlet pipe D₁ joins into or forms a part of the branch pipe G
and the syphon G¹ connection to the delivery pipe for the flush. The base of
the cylinder A is provided with inlets or apertures C¹ see Fig. 2, or valves may be
used if preferred.
In some cases a valve II may be fitted at the junction of the inlet pipe D¹, brauch
pipe G and syphon G¹.
Oi in some cases the branch pipe G may join into the top of the cylinder A, see
Fig 1 and in this case the piston or displacer works in an upward direction to close
the branch pipe G when required. The inlet D' and branch pipes G are in this
case made as one, or joined into each other, and the syphon G is joined into them
at on about their junction, see Fig. 2.
The valves D are arranged in connection with and preferably underneath the
branch or suction pipe G so that when the piston or displacer B closes the branch
pipe G or outlet pipe, the suction in the sy phon G' lifts the valve D and causes the
water to flow through the syphon. In some cuses a valve may be used in connection
with the suction pipe.
The piston or displacer B may be loose on its rod or valves may be used in
connection with it.
In some cases the inlet or suction pipe may be jomed into or form a part of the
stand or delivery pipe, as shown in dotted lines see Fig. 2.
The displacer or piston B may be so ai ranged as to close both or either ends of
the charging chamber A by employing discs or diaphragms upon the piston rod or
spindle, the brauch or suction pipe G in this case may be part of or attached to the
cylinder or charging chamber A.
Fig. 6. In this view B is the outlet opening, the piston B is guided into and
held in position by the stud or projection K upon the branch pipe G, the said
piston having a hole or recess for engaging with such stud or projection or a
feather J may be used. The enlargement L shown in dotted lines is for when
the pistons shown in Figs. 11 and 12 are used
'
Figs. 7 and 18. The outlet H 18 in the side of the chamber A with which the
branch G is formed or made as one.
Figs. 9 and 10. The pistons B are provided with feathers J for guiding the
pistons. The one shown in Fig. 10 may have a hole through the face of it and a
valve, as indicated by the dotted lines J, for closing such hole when required.
Figs. 11 aud 12. The pistons Bave provided with discs F, and openings F', so
that when the piston is pushed forward the action of the water on the discs closes
the said openings. The return action causes the said discs to open the said
valves F1.
Fig. 13. The chamber A and brauch pipe G are made as one. The piston B is
provided with a lift valve as shown in dotted lines, the water passing through as
indicated by the arrows.
Fig. 14. The piston B has a shield J' for closing the outlet II', when the piston
1s in the position shown in the drawing.
Fig. 15. This is a view showing cistern with the arrangement shown in Fig. 18
applied.
Fig. 16. The outlet II is arranged centrally and the action is the same as
Fig. 18
In Fig. 17. The piston B is provided with a shield B' which covers outlet B³ of
charging chamber or cylinder A, by this meaus, the liquid is prevented from
passing through the chamber A during the flushing operation. B is a shield or
diaphragm and stop (for pistou or plunger B) to prevent air acting on the flush
and to prevent the plunger or piston B coming out of the cylinder or charging
chamber A.

page_text: Fig 17 is a slight modification of Fig. 17 having the valve D arranged at a
different position to Fig. 17.
Fig. 18. In this case a central outlet opening II', in the branch pipe G, is
provided immediately opposite the plunger or displacer B which is provided with
a cushion or plate E' for closing the said opening when the plunger or piston is 80
operated.
The faces of the said parts II' and II' may be machine metal faced, or leather,
india-rubber composition, or the like faces may be used.
A well C is arranged under the branch pipe G which is fitted with a valve D,
by means of the said well the whole of the liquid in the cistern or container can be
drano off. The dotted lines in this figure show a modification in the shape or
construction of the branch pipe G.
Or they
Fig. 19. In these views the outlet opening II and cushion or plate H' are
arranged lower, or upon the level of the lower side of the cylinder A.
may be ai rauged at the top side, if preferred.
The branch pipe G is shorter than that shown in Fig. 18.
Figs 20, 21, 22, and 25. The outlet opening H₁ may be joined at any point in
the cylinder or chamber A. The piston B (see Fig. 25) being provided with a
shields to cover the hole or outlet H', so as to prevent liquid passing through
the chamber or cylinder A during the flushing operation. The dotted lines in
Figs. 21 and 22 indicate modifications of these figures.
Figs. 23 and 24. The ontlet Hand cushion or face fl' are arranged centrally,
but in Fig. 24 the outlet to the branch pipe G is in the side of the cylinder A,
and is covered when the flush is on by the shield H. The branch pipe G in both
cases being fitted with valves D at the top or bottom.
Fig. 26 This arrangement is substantially the same as Fig. 19, a button valve D'
being employed instead of a flap or lid valve.
Having now particularly described and ascertained the nature of my said inven-
tion and in what mauner the same is to be performed I declare that what I
claim is :-
1. In flushing apparatus for cisterns, lanks, and the like, forming the flush without
taking the liquid through the displacer chamber or cylinder, by causing the displacer
or piston to create a suction or vacuum . the inlet and branch pipes, substantially
as shown and described.
2. In flushing apparatus for cisterns, tanks, and the like, discharging the entire
contents of the cistern, tank, or other container, in the manner substantially as set
forth.
•
3. The combination of parts forming the several arrangements of flushing
apparatus for cisterns, tanks, and the like, as shown and described.
