THOMAS GARFORTH RHODES, Engineer Albert Terrace, Kirkstall, Leeds,
FRED RAWSON Plumber Beaconsfield Terrace Kirkstall Leeds RAYMOND GAUNT
Engineer The Mount Stauningley Leeds, do hereby declare the nature of this
invention to be as follows:-
This invention has for its object the construction of valveless syphons for draining
cisterns tanks & the like: and consists of a bent pipe forming a syphon to the short
leg of which is attached a horizontal or inclined cylinder. One end of the said
cylinder is closed, sliding in the cylinder is a piston or disc so arranged by levers
& connections that the pull gives to the said piston or disc a movement along the
said cylinder the short leg of the syphon pipe is attached to the said cylinder in
such a manner that the piston or disc in its inward or outward motions passes the
hole communicating with the short leg of the syphon pipe & thus forms its own
valve. The action is as follows. Suppose the said syphon to be fitted in a cistern,
the cylinder fixed to the short leg of the syphon being at the bottom of the cistern;
upon filling the cistern with water it of course fills the said cylinder & syphon up
to the desired height. Upon the piston or disc (which is sufficiently free to allow
the cylinder to fill) being given an inward movement the water in the cylinder is
forced over the syphon bend thus starting the syphon action. The piston or disc
in its inward movement passes the hole connecting the syphon leg with the cylinder
& thus completes the connection between the syphon & the water in the cistern.
Also the piston or disc by the suction of the syphon is held forward until the water
subsides to the level of the said cylinder; when by the action of a weighted lever
the piston or disc is drawn back ready for another stroke.

An Improved Valveless Syphon for Draining Cisterns, Tanks, and
the like.
THOMAS GARFORTH RHODES, Engineer, Albert Terrace, Kirkstall Leeds
FRED RAWSON Plumber Beaconsfield Terrace Kirkstall Leeds RAYMOND GAUNT,
Engineer, The Mount, Stanningley, Leeds. We 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 has for its object the construction of valveless syphons for draining
cisterns, tanks & the like; and consists of a bent pipe forming a syphon to the short
leg of which is attached a horizontal or inclined cylinder. One end of the said
cylinder is closed, sliding in the cylinder is a piston or disc so arranged by levers &
connections that the pull gives to the said piston or disc a movement along the said
cylinder the short leg of the syphon pipe is attached to the said cylinder in such a
manner that the piston or disc in its inward or outward motions passes the hole

page_text: communicating with the short leg of the syphon pipe & thus forms its own valve.
The action is as follows: Suppose the said syphon to be fitted in a cistern, the
cylinder fixed to the short leg of the syphon being at the bottom of the cistern:
upon filling the cistern with water it of course fills the said cylinder & syphon up
to the desired height. Upon the piston or disc (which is sufficiently free to allow
the cylinder to fill) being given an inward movement the water in the cylinder is
forced over the syphon bend thus starting the syphon action. The piston or disc
in its inward movement passes the hole connecting the syphon leg with the cylinder
and thus completes the connection between the syphon & the water in the cistern.
Also the piston or disc by the suction of the syphon is held forward until the water
subsides to the level of the said cylinder; when by the action of a weighted lever
the piston or disc is drawn back ready for another stroke.
The drawings show different arrangements of syphons to cisterns.
Fig. 1 shows an arrangement of syphon to lead lined cistern and consists of a
cylinder A syphon bend B: piston or disc C: lever D: support E for lever
shown in another view by Fig. 2; & so arranged as to give a clear space in cistern
for ball tap, and to facilitate the means of taking the parts from together.
Partition Finto which is taken a small bent pipe G which joins the syphon
pipe B at the union H such arrangement is for causing the afterflush & consists of
a syphon put into action by the means of the main syphon B.
:
Fig. 2 shows an arrangement of syphon in lead lined cistern & consists of a
cylinder A such cylinder is provided with a conical outlet I, & recess J for the
reception of the conical end of syphon B. The short leg of syphon B is formed to
fit the conical outlet I & recess J in cylinder A; the object of which is to prevent
the cylinder A from turning out of position & at the same time to form a joint
between cylinder A & syphon bend B. This joint may also be formed by casting
a coarse quick threaded screw in the conical hole in cylinder, and a corresponding
thread on the conical end of syphon bend.
Fig. 2 shows a plan of conical end of syphon pipe B.
Fig. 3 shows the same arrangement as Fig. 1 with the exception that the syphon
bend is taken over the top of cistern & down the outside of same.
Fig. 4 is another modification like Fig. 1 with the exception that in the place of a
division or partition F a cylinder K may be substituted for containing the water
necessary for the afterflush.
Fig. 5 shows an arrangement of iron cistern & consists of a cistern L provided
with raised lugs L' for holding the lever stud so that the fittings may be reversible.
The said lugs L' may be both on one side; or one on one side, & one on the opposite
side. The cistern L is also provided with a ledge M which projects all round,
such ledge M forms a seat for the reception of a cover plate N which is cast with a
conical hole to fit the end of syphon bend P; the conical end of the said syphon
bend P is provided with a recess Q for the reception of some elastic material for
making the joint. The end of the syphon bend P fitting the conical hole O of the
plate N which is taken across cistern & rests on the ledge M provided on cistern L:
forms the syphon bend and flushing chamber. The displacer R is made to the form
of the flushing chamber. The connection of the displacer and lever are formed so
as to make a book joint thus dispensing with the use of pins or other mechanical
equivalents. The cover T is provided with two gaps for lever S to work through
for each hand.
Fig. 6 shows an arrangement for working syphon cistern by the action of the seat
& consists of a rod U provided with a weight U. To the seat is fitted a fork
lever V, operating the rod. U by means of a collar W fixed to the said rod U.
The action is as follows Upon pressing down the seat it raises the rod U by means
of the fork lever V; which in turn by means of levers draws the displacer or
piston to the end of the cylinder; & upon releasing the seat the weight U' acting
through the said rod U, & levers is sufficient to operate the displacer or piston for
charging the syphon.

page_text: Having now particularly described & ascertained the nature of our inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is.

syphon bend B: piston or dise C: lever D: support E: partition F: small bent
pipe G union H: all arranged substantially as described and set forth.
2. An arrangement of syphon cistern like Fig. 2. The cylinder being provided
with conical hole I, & recess J for the reception of the conical end & key of the
syphon bend. Or the said conical hole may have a quick threaded screw cast in, &
upon the conical end of the syphon hend may be cast a corresponding screw.
arranged substantially as described and set forth.
All
3. An arrangement of syphon cistern like Fig. 3 in which the syphon bend is
taken over the top & down outside of cistern.
4. An arrangement of syphon cistern like Fig. 4 in which a cylinder is provided
