PROVISIONAL SPECIFICATION left by Thomas Wright Gardener Treeby
at the Office of the Commissioners of Patents, with his Petition, on the
4th March 1857.
I, THOMAS WRIGHT GARDENER TREEBY, of No. 1, Westbourne Terrace
Villa, Paddington, in the County of Middlesex, do hereby declare the nature
of the said. Invention for "IMPROVEMENTS IN SEWERS AND GULLEYS, AND OUTFALL
TO SEWERS AND GULLEYS AND OF SEWAGE," to be as follows:-
First, an improvement on my last Patent, dated Thirteenth day of Novem-
ber, One thousand eight hundred and fifty-six, for gulleys to sewers. Next
is a sluice gate to outfall of sewer with cassoun floats. Next is an improve-
ment on the syphon for raising water and sewage from low levels. I will
now explain them more fully.
First, with respect to gulleys. I now declare that the pipes used for
gulleys. may be entered any part of the sewer, and that my trap, hinged to
the common earthenware pipe by a band passing round or otherwise, and
acting as I mentioned in my last Patent as a key or valve, or trap, hinged
at the end of a common drain pipe, as commonly used for drains. Now,
let it be known, that I trap the gulleys by means of the common pipe,
dipping into water contained in a pan, and the action is the same as in
my-last-mentioned Patent, with this difference, that I trap the gulleys in the

page_text: sewer or any part of the sewer where the water passes from the surface of
street or land.
My next plan connected with sewers is an improvement in sluice gates, to
prevent the sewage passing up rivers or brought towards the land as the
tide flows. First, I propose to have a gate or door, to move vertically in
grooves, slots, guides, or otherwise; secondly, I propose to have one or more
cassoun or floats to rise and fall, as the tide ebbs and flows, attached to the
sluice gate or door to open and shut it. These may be made of wrought iron
or other material suited for the occasion, and may move in slots, grooves, or
other guides for the floats to rise and fall with the tide, so as the tide recedes
the floats fall with the gate, which allows the sewage or water to escape with
the tide; and as the tide flows, the float or floats, and gate or gates or door
rise, close the mouth of the sewer, and prevent the sewage or water passing
out, and thus preventing any sewage or water passing up rivers or coming
towards the coast, as it can only escape when the tide recedes. This appa-
ratus is all self-acting.
Next is an improvement on syphons, to be applied for raising sewage
out of low drains or sewers, by having one or more syphons, as the case
may require. Instead of only having two cocks or valves at one end, as are
now commonly used, I have one cock or valve at each end of the syphon,
and one cock or valve on the highest part of each syphon, so that when
the cocks are closed at each end, water may be put in at the top, and
thus drive out the air. This may be done by an engine, or otherwise, so
when the syphon is charged with sewage or water the valve or cock at the
top must be shut, the lowest cocks at the end to be opened, and the water or
sewage will immediately ascend and pass away to the lowest level. The
object of putting in water at the top of the syphon is, that no part of the
engine would be effected by the sewage. Clean water to be used when the
syphon wants charging at the top of the syphon.or syphons. Each cock
must be connected with an open mouthed funnel, or apparatus, so as the water
passes into the syphon the air may pass out as soon as the syphon is full of
water; the top cock should be closed, the lower two opened, and the sewage
will commence running in the usual way. By having more than one syphon,
I may always keep them charged when not in work, and by having floats in
the receptacles for sewage attached to an index string may be attached to a
bell to call the man's attention; and as the sewage flows into the receptacle,
the cocks or valve at the lowest part must be opened, and away goes the
sewage through the syphons to the outfall, thus getting rid of all the sewage
in the low level sewers with a very small expense; and as it will only require

page_text: a very small engine to charge the syphon when required, no sewage, if clean
water is used, can by any chance get to the works of the engine.
Having now described the nature of my Invention, I wish it to be under-
stood that what I claim is,
First, I claim as my Invention the trapping of gulleys by means of the
common pipe dipping into a dish or pan; the pipe fixed vertically.
Second, I claim next as my Invention the sluice gate to be attached to
cassouns or floats for rising and falling gates to outfall of sewers.
Third, I claim also as my Invention the improvement on syphon, the cock
placed on the top, and cock at each end, instead of the two cocks at one end.
