Improvements in Apparatus for Controlling Sluice Ways or Outlets
Discharging into Tidal Waters.
I, GILES WEBBER CARTER, of 22 Joy Street, Barnstaple, in the County of Devon,
Plumber and hot water Engineer, do hereby declare the nature of this invention to be
as follows:-
This invention relates to self acting tidal valves employed for controlling the outlets
of sewers, drains and the like that discharge their contents into tidal rivers or seas.
My apparatus comprises a valve which may be of the flap type hinged near and so as
when shut to close the outlet of the sewer or drain; this valve is connected to a lever
able to turn upon a suitable hinge and provided with a float the arrangement being
such that when the tide rises the float will be raised and, through the lever and before
mentioned connection will close the valve firmly against its seat, whilst when the tide
falls, the float will fall with it and automatically open the valve.
The float may be a hollow vessel or chamber secured to one end of a lever of the
second order, the other end of which is hinged to a bracket carried by a plate to
another part of which the valve is also hinged, the lever being provided with an arm
or projection to which is secured one end of a rod, formed at its other end with a hook
A seating of suitable material such
that engages in an eye projecting from the valve.
as leather or india-rubber is provided to ensure a tight joint between the valve and its
seat when the valve is closed.

I, GILES WEBBER CARTER of 22 Joy Street Barnstaple, in the County of Devon,
Plumber and hot water 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 :-
This invention relates to self acting tidal valves employed for controlling the outlets
of sewers, drains and the like that discharge their contents into tidal rivers or seas
My apparatus comprises a valve which may be of the flap type hinged near and so as
when shut to close the outlet of the sewer or drain; this valve is connected to a lever
able to turn upon a suitable hinge and provided with a float the arrangement being
such that when the tide rises the float will be raised and through the lever and before
mentioned connection will close the valve firmly against its seat whilst when the tide
falls the float will fall with it and automatically open the valve.
The float may be a hollow vessel or chamber secured to one end of a lever of the
second order the other end of which is hinged to a bracket carried by a plate to another
part of which the valve is also hinged the lever being provided with an arm or
projection to which is secured one end of a rod formed at its other end with a hook
that engages in an eye projecting from the valve. A. seating of suitable material such
as leather or indiarubber is provided to ensure a tight joint between the valve and its
seat when the valve is closed.
Referring to the accompanying two sheets of drawings Fig. 1 shows in side
elevation partly in section, apparatus according to this invention applied to the outlet
of a drain or sewer. The apparatus is represented as situated within a chamber,
shown in vertical section, into which tidal water may flow. The figure shows in full
lines the positions of the several parts of the apparatus when the valve is open, and in
dotted lines their positions when the valve is closed.
Fig. 2 is a front elevation of the apparatus in the position it occupies when the
valve is open.
1 is a flap valve hinged at 2 to a plate.3 secured at the outer end of the drain or
sewer 4 whose outlet is to be controlled. The plate 3 is provided with an opening 5
and a valve seat 6. 7 is an eye or ring on the outer side of the valve and 8 is a
seating of suitable material such as leather or india rubber on the inner side thereof.
9 is a lever hinged at 10 to a bracket 11 carried by the plate 3; it bas at its outer end
a float 12 and is provided with an arm or projection 13. 14 is a rod secured at one
end to the arm or projection 13 and formed at its other end with a hook 15 that
engages with the eye or ring 7. The apparatus is by preference placed in a chamber 16
as shown (or in a casing into which tidal water may flow) in order that it may be
protected from damage by bodies that may be floating in such water.

page_text: With apparatus such as hereinbefore described and shown the rising of the tidal
water will cause the float 12 to lift the lever 9 and rod 14 and force the valve firmly
against its seat 5, whilst when such water falls the float and attached lever and rod fall
into the positions shown in full lines, automatically opening the valve, and permitting
of an outflow from the drain or sewer.
:-
Having now particularly described and ascertained the nature of this invention and
in what manner the same is to be performed I declare that what I claim is :-
The improved apparatus for controlling sluice ways or outlets discharging into tidal
waters, substantially as described.
