PROVISIONAL SPECIFICATION.
Improvements in Drawing Off Water or Liquid from Sewage Tanks
or Reservoirs.
I, FREDERIC GEORGE SISON HAM, of 13, Grosvenor Road, Westminster,
Engineer, do hereby declare the nature of this invention to be as follows:-
Improved method of automatically drawing off water or liquid in reservoirs
without disturbing the sediment at the bottom of reservoir.
I provide a pipe suspended by a float at its upper end to keep the mouth
of the pipe always at or near the surface of the liquid. whilst the other end of
pipe is bolted up to a bend pipe. This bend pipe is provided with a swivel
joint so that the pipe may rise or fall with the water.
I connect this swivel joint with the floating pipe attached to the inlet leg of
an automatic flushing syphon.
This enables me to draw off the water in reservoir at or near the surface
without disturbing the sediment or sludge that settles at bottom.
The liquid will flow down the suspended pipe and up the leg of the syphon
but will not discharge until the water reaches to the top of syphon leg. The
syphon then discharges drawing off the liquid from or near to the surface of
reservoir without disturbing the deposit on the bottom.
This operation will be repeated each time the water in the reservoir rises
to the top of the syphon leg.

FREDERIC GEORGE SISON HAM,. 13, Grosvenor Road, Westminster, S.W.,
Engineer, 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:-
I provide a pipe suspended by a float at its upper end to keep the mouth of
the pipe always at or near the surface of the liquid whilst the other end of the
pipe is bolted up to a bend pipe. This bend pipe is provided with a swivel joint
so that the pipe may rise or fall with the water. I connect this swivel joint
with the floating pipe attached to the inlet leg of an automatic syphon. This

page_text: method enables me to draw off the water in reservoir at or near to the surface
without disturbing the sediment or sludge that settles at bottom.
The liquid will flow down the suspended pipe and up the leg of the syphon
but the syphon will not discharge, or, go off, until the water reaches the top
of the syphon leg. When however the liquid rises to a sufficient height the
syphon will come into operation and discharge the liquid taking however the
liquid from the surface without disturbing the sediment or sludge at bottom of
the tank.
The accompanying drawing shows the general arrangement of the combined
method enables me to draw off the water in reservoir at or near to the surface
without disturbing the sediment or sludge that settles at bottom.
The liquid will flow down the suspended pipe and up the leg of the syphon
but the syphon will not discharge, or, go off, until the water reaches the top
of the syphon leg. When however the liquid rises to a sufficient height the
syphon will come into operation and discharge the liquid taking however the
liquid from the surface without disturbing the sediment or sludge at bottom of
the tank.
The accompanying drawing shows the general arrangement of the combined
apparatus.

Fig. C, the swivel joint.
Fig. D, the automatic syphon.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is ―
The combination of an automatic syphon and a floating arm or pipe sub-
stantially as described and shown.
