Improvements in Automatic Syphons.
We, WILLIAM DEWAR, of 23, Montrose Street, Glasgow, Lanarkshire, Engineer
for the Sanitary Department of Glasgow, and JOHN SKELLY, of 180, Lothanhill, by
Dunaskin, Ayrshire, Colleries Foreman, do hereby declare the nature of this in-
vention to be as follows :-
This invention relates to automatic syphons to be used for flushing purposes
and also as grease, oil, or other liquid separators, the object being to provide a
reliable and at the same time an inexpensive syphon.
The improved syphon is composed of a tank into which the water from a steam
engine or other source containing oil, or other liquid to be separated, is led, the
tank being provided with a pipe bent to this form viz., . One leg of this pipe
is carried through the bottom and the other leg is terminated short of the bottom
of the tank. A short distance above the lower end of this latter leg a straight pipe
is connected which has its upper end carried above the bend of the shaped
pipe and is open to the atmosphere.
In the action of the apparatus the water from which the oil is
to be separated or the chemical liquid to be separated, is led
into the tank and ascends the short leg of the bent tube, at the same time
ascending the straight tube connected therewith until the bend of the shaped
pipe is reached when the water overflows and a complete syphoning action takes
place. The oil or other liquid lighter than the water which has previously collected
on the top is now left on the bottom of the tank by the outflowing water and may
be collected at any time.
The apparatus acts in the same manner when used for flushing purposes.
Improvements in Automatic Syphons.
We, WILLIAM DEWAR, Engineer, formerly of the Sanitary Department, 23, Mont-
rose Street, Glasgow, in the County of Lanark, now of 180, Lethanhill, by
Dunaskin, and JOHN SKELLY, Colliery Manager, 180, Lethanhill, by Dunaskin, in
the County of Ayr, 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 relates to automatic syphons to be used for flushing purposes and

page_text: also as grease, oil, or other liquid separators, the object being to provide a reliable
and at the same time an inexpensive syphon.
As shewn by the explanatory drawing hereunto annexed, Figure 1 of which is a
vertical section and Figure 2 a plan of the syphoning apparatus, the improved
syphon is composed of a tank, into which the water from a steam engine or other
source containing oil, or other liquid to be separated, is led, the tank 1 being
provided with a pipe bent to this form, viz., . One leg 2 of this pipe is carried
through the bottom and the other leg 3 is terminated short of the bottom of the
tank. A short distance above the lower end of this latter leg 3 a straight pipe 4
is connected which has its upper end carried above the bend 5 of the shaped pipe
and is open to the atmosphere.
In the action of the apparatus the water from which the oil is to be separated or
the chemical liquid to be separated, is led into the tank 1 and ascends the short
leg 3 of the bent tube, at the same time ascending the straight tube 4 connected
therewith until the bend 5 of the shaped pipe is reached when the water over-
flows and a complete syphoning action takes place. The straight pipe 4 admits
air and stops the syphoning action when the water falls below the uppermost point
of the connection of the pipe 4 with the leg 3. The oil or other liquid lighter
than the water which has previously collected on the top is now left on the bottom
of the tank by the outflowing water and may be collected at any time.
The apparatus acts in the same manner when used for flushing purposes.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1. The improved automatic syphon having its component parts constructed,
arranged and combined substantially as described with reference to the annexed
explanatory drawings.
2. An improved automatic syphon for use for flushing purposes and also
applicable as a grease or other liquid separator consisting of a tank in combination
with a bent pipe one leg of which projects through the bottom of the tank and the
other is terminated short of the inside of said tank and a vertical pipe connected to
the short leg of the bent pipe substantially as described.
