I, HENRY MALCOLM RAMSAY, of 2, Russell Villas, Pope's Grove,
Twickenham, in the County of Middlesex, Civil Engineer, do hereby
declare the nature of the said Invention for 66 IMPROVEMENTS IN THE
TREATMENT OF SEWAGE OR OTHER LIQUIDS OR SOLUTIONS, AND THE PRODUCTION
THEREFROM OF MANURANCE PRECIPITATES OR OTHER SOLIDS, AS, ALSO FOR RAISING
SEWAGE OR OTHER LIQUIDS OR MATTERS BY FLOATING TANKS OR BY THE ACTION
OF TIDAL WATERS," to be as follows:-
For the purposes and requirements and means for carrying out this
process, or for raising or lifting the sewage or other matters, I design,
fit up, arrange, construct, operate, and work the several appurtenances,
apparatus, constructions, materials, liquids, and powers, obtained as
under mentioned.
A. Receiver for Sewage, etc.-First. The sewage or other liquid or
solution to be collected at. outfall or other arrangement into certain
chambers, cisters, or other suitable receptacles. The sewage or other

page_text: liquids or solution being discharged or flowing into same by the action
of pumping, or lifting power, or by gravitation.
B. Precipitation Pans.-Second. From the receiver "A" the sewage
or other liquid or solution shall flow, pass along by gravitation through
one or more closed or open troughs, pipes, conduits, or other channels,
and discharge therefrom into one or more precipitation pans.
C. Precipitant Bath.-Third. The necessary mixture or precipitant
being prepared or mixed in the bath is to be conveyed from same by a
service or supply pipe to be affixed to the trough or troughs, or other
channels before mentioned, and to be ejected therefrom into the same,
and thereby become equally mixed with the sewage or other fluid
flowing into precipitation pans.
D. Press Chamber.-Fourth. Attached to or adjoining the precipitation
pans shall be fitted up a perforated bed plate or pockets or bags and
top press plates for the expression of or squeezing out the moisture or
liquid from the precipitate; this object to be obtained, effected, or
applied by hydraulic pressure, or by screws, levers, weights, or other
apparatus or fittings to be acted up by steam, water, or manual power,
the moisture or liquid being thereby expelled from the precipitate matter,
the water or liquid so discharged from precipitate being collected in
channel under and passing therefrom into foul water drain.
E. The Drying Chamber or Flues.-Fifth. Attached to or adjoining
press chamber D shall be an enclosed space to be heated by hot air
flues, steam or hot water pipes, and to the necessary height, width, and
length for the reception of the false bottom or bed plate or floor of the
pans B upon which the precipitate has been deposited.
F. The False Bottom or Bed Plate in Pans.-Sixth. Each pan shall
be fitted up with a false bottom, upon which the precipitate shall
deposit, such false bottom being constructed of canvass or copper
wire, or other suitable webbing fitted or strained into proper framing,
or of perforated iron; zinc, or copper plates connected with same, shall be
fitted all necessary bed or other rollers, chains, and other necessary
apparatus for the purpose of conveying or hauling or carrying the bed
plate when loaded with precipitate from the pan or pans under press,
and from thence into drying chamber, and returning same to pan when
precipitate has been removed, the whole being worked or moved by
steam, water, or manual power.

page_text: G. The Supernatant Water and Filter.-Seventh. Each pan or pans
to be fitted up with proper openings for the discharge from the pans
of the supernatant water into certain filters or filtering beds, as also for
the discharge of the foul water from the deposit, the effluent water after
filtration passing off in clear water drain.
H. The Raising or Lifting Sewage or other Liquids or Substances.—
Eight. By the construction of an open well. or other receptacle for
holding water constructed to the necessary size or dimensions according
to the tank or weight to be raised, floated, or lifted therein. By the
construction of an open tank with the lower portion divided as an air
or water-tight compartment, such tank to be acted upon for the purposes
required of certain appliances, pumps, etc., necessary to charge or
empty such compartment with air or water, or by the use, application,
and admission of tidal waters into such well or receptacle, so that the
tank will rise to level required, such level subject to the action of the
tides in the particular locality.
