WALTER PETER CHERRY and CHARLES EDWIN CHERRY, both of Porter Street,
Kingston-upon-Hull, in the County of York. IMPROVEMENTS IN THE CONSTRUCTION
OF PORTABLE SIPHONS."
The object of our Invention is to construct portable siphons in such a manner
so as to be kept charged with water or other liquid, and ready for use without
having to exhaust the air from the siphons to set the same in action every time
they are used as commonly practised.
For this purpose we provide and fix on the end of the short limb of a siphon a
stop cock or valve, having a cup or bend pipe attached thereto, and on the end of
the long limb of the siphon we provide and fix a stop cock or valve.
In order to set the siphon in action it is filled with water or other liquid, the
stop cock or valve on the long limb of the siphon is then closed, the stop cock or
valve with a cup or bend pipe attached thereto on the short limb of the siphon
remains open, and when turned downwards the water or liquid is prevented from
running out of the siphon by means of the atmospheric pressure on the surface of
the liquid in the cup or bend pipe which acts as a seal, the short limb of the siphon
is then immersed in the water or other liquid in the cask or vessel to be discharged,
the stop cock or valve on the long limb of the siphon is then opened and the liquid
flows out. When removing the siphon from the cask or vessel the stop cock or
valve on the long limb of the siphon is closed, the short limb of the siphon is then
drawn out of the cask or vessel, and the pressure of the atmosphere on the surface
of the liquid in the cup or bend pipe prevents the liquid from running out of the
siphon; the stop cock or valve on the short limb of the siphon is then closed and
the siphon remains charged with liquid, and is.ready for use again.
When again using the siphon the stop cock or valve with the cup or bend pipo
attached thereto on the short limb of the siphon is opened and then turned down-
wards and is immersed in the liquid in the cask or vessel to be run off and the
stop cock or valve on the long limb of the siphon is then opened and the liquid
flows out.
In another form of siphon we fix a stop cock or valve on the short limb of the
siphọn with a perforated rose or tube with perforated grate attached thereto, in

page_text: room of the cup or bend pipe as used in the other siphon hereinbefore described,
the perforations being made small enough to prevent the atmosphere from pressing
through the grate or rose to empty the siphon when the siphon is charged with
liquid a stop cock or valve being provided on the end of the long limb of the
siphon; the manner of using this siphon is precisely in the same way as the one
herein before described. And by another way of making a portable siphon we
employ a piece of india rubber or other flexible tube, and fix on one end of the
-tube-a-stop-cock or valve with a-cup or-bend-pipe,-or-a-stop-cock-or-valve-with-a-
perforated rose or tube with perforated grate attached thereto, and on the other
end of the tube we fix a stop cock or valve; the tube is then charged with water
or other liquid and the stop cock or valve is then closed; the stop cock or valve
with a cup or bend pipe, or with a perforated rose on the other end of the tube, is
then opened and turned downwards, and the pressure of the atmospheric air
prevents the water or liquid from running out of the tube, this end of the tube is
then immersed in the water or other liquid in the cask or vessel and the other end
of the flexible tube with a stop cock or valve fixed thereto is bent down at the
outside of the cask or vessel below the level of the water or liquid in the cask or
vessel, the cock or valve is then opened and the liquid flows out. When removing
the tube from the cask or vessel, the cock or valve is closed and the other end of
the tube is drawn out of the cask or vessel, the pressure of the atmosphere preventing
the liquid from running out of the tube, the cock or valve with a cup or bend pipe
at this end of the tube is closed, and the flexible tube remains charged with liquid
and is ready for use again. In another form of siphon, we fix on the short limb of
the siphon a cup or bend pipe or a perforated rose, or a tube with perforated grate
or valve, but without a stop cock, and on the long limb of the siphon we fix a stop
cock or valve; this siphon is used in a similar manner to those hereinbefore
described, but when the short limb of the siphon is drawn out of the cask or vessel
the cup or bend pipe, or perforated rose, or tube with perforated grate or valve,
prevents the liquid from running out by means of the atmosphere. This siphon
must be kept in an upright position to keep it charged with liquid to be ready for
use again.
