SYPHONS."
"IMPROVEMENTS IN
The object of the said Invention is to replace the present troublesome means of
starting or charging the syphon by sucking with the mouth, and for this purpose I
employ a pipe which can be moved to and fro in a sleeve which communicates with
the liquid to be syphoned. The sides of this pipe and sleeve which touch each
other are made water tight.
The sleeve carries a short piece of pipe for the connexion of a hose which is led
to the liquid to be syphoned.
The aforesaid pipe is furnished with a suction valve which opens when the pipe
is pushed inwards in the sleeve and closes directly the pipe is moved in the opposite
direction. In the latter movement the pipe acts as a suction piston drawing the
fluid after it.
When several of the above described to and fro movements of the pipe have been
made the liquid passes through the suction valve into a suitable valve chamber and
flows out through the orifice thereof. This orifice may be opened or shut at will
by means of a hemispherical valve fixed to a short moveable pipe. This valve
closes of itself when the liquid enters the valve chamber, unless the short moveable
pipe is fastened in an open position. The end of the syphon which is immersed in
the liquid to be syphoned is furnished with another valve so that the charged
syphon can be moved from one vessel to another without allowing the liquid to
escape from either of the two orifices.

JOSEPH DELORD, resident at Nimes, in the Republic of France. "IMPROVEMENTS
IN SYPHONS."
The object of the said Invention is to replace the present troublesome means of
starting or charging the syphon by sucking with the mouth, and for this purpose I
. employ the following simple arrangements and manipulation.
In Figures 1 and 2 of the Drawing a is a pipe which can be moved to and fro in
the sleeve b which communicates with the liquid to be syphoned. The sides of the
pipe a and sleeve b which touch each other are made watertight. The sleeve b
carries a short piece of pipe for the connexion of a hose which is led to the liquid
to be syphoned.
The aforesaid pipe a is furnished with a suction valve c, which opens when the
pipe a is pushed inwards in the sleeve b and closes directly the pipe a is moved in
the opposite direction.
In the latter movement the pipe a acts as a suction piston drawing the fluid
after it. When several of the above described to and fro movements of the pipe
have been made the liquid passes through the suction valve c into the valve chamber d
and flows out through the orifice e.
The hemispherical valve fis fixed to a short moveable pipe g, and the outlet
orifice can be opened or shut thereby at will by means of the button h. The valve f
closes of itself when the liquid enters the valve chamber d, unless the pipe g is
fastened in its open position by means of the bayonet joint i and the button h.
The strainer (Figure 3), which is immersed in the liquid to be syphoned, is
furnished with another valve 1, so that the charged syphon can be moved from
one vessel to another without allowing the liquid to escape from either of the two
orifices.
Having now described the nature of the said Invention, and the manner in
the same is to be carried into effect, I would have it understood that what I claim
as my Invention is,―
First. The combination of the pipe a with the sleeve b, the valve c, the valve
chamber d, and the valve f, as herein before described and illustrated in Figures 1
and 2 of the Drawing, and for the purpose set forth.
Second. The application and use of a valve in the suction strainer k, as herein-
before described and illustrated in Figure 3 of the Drawing and for the purpose set
forth.
In witness whereof, I, the said Joseph Delord, have hereunto set my hand and
seal, this Twenty third day of May, in the year of our Lord One thousand
Witness,
JOSEPH DELORD. (L.S.)
