Complete Specification Left. 18th Mar.. 1895-Accepted, 20th Apr., 1895
I, FRANCIS GOULD MORONY STONEY, of Waterside Works, Ipswich, in the
County of Suffolk, Engineer, do hereby declare the nature of this invention to be
as follows, that is to say :-
My said invention has for its object to provide an improved arrangement of
automatic sluice for ponded waters and the like, such sluice being such as to allow
excess water to pass off under it.
In carrying out my invention employ my well-known free-roller balanced sluice
and comment it to one end of a long lever, or lever frame, which has its fulcrum
upon a beam or girder fixed across the channel leading to the sluice.
At a part of
the lever near its fulcrum and between the fulcrum and the part of the lever to
which the sluice is connected, I connect a float which rises and falls with the level
of the water, and which causes the lever to raise the sluice whenever the water
level exceeds a predetermined height. Where convenient the lever or lever frame
may be extended beyond the fulcrum away from the sluice, and have attached a
weight to counterbalance the sluice and other parts. Or the sluice and other parts
may be counterbalanced by weights acting on chains passing up to and over pulleys
and down to the sluice.

Improvements in Automatic Sluices.
1, FRANCIS GOULD MORONY STONEY, of Waterside Works, Ipswich, in the
County of Suffolk, 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, that is to say :—
My said invention has for its object to provide an improved arrangement of
automatic sluice for ponded waters and the like, such sluice being such as to
allow excess water to pass off' under it.
In carrying out my invention I employ any well-known free-roller balanced sluice,
and I connect it to one end of a long lever, or lever frame, which has its fulcrum
upon a beam or girder fixed across the channel leading to the sluice. At a part of
the lever near its fulcrum, and between the fulcrum and the part of the lever to
which the sluice is connected, I connect a float which rises and falls with the level
of the water, and which causes the lever to raise the sluice whenever the water
level exceeds a predetermined height. Where convenient, the lever or lever frame
may be extended beyond the fulcrum away from the sluice, and have attached a
weight to counterbalance the sluice and other parts. Or the sluice and other parts
may be counterbalanced by weights acting on chains passing up to and over pulleys
and down to the sluice.

page_text: And in order that my said invention and the manner of performing the same
may be properly understood, I hereunto append a sheet of explanatory drawings, to
be hereinafter referred to, and showing by way of example an automatic sluice ns
made and arranged according to my invention.
Figure, 1, of the drawings is a horizontal section of a part of the sluice and
showing the arrangement of free rollers, A, and a vertical staunching bar, B.
Figure, 2, is a side elevation of my improved float and lever in combination with
my well-known free-roller sluice, one side of the channel being supposed to be
removed.
In these drawings the same reference letters are used to mark the same or like
parts wherever they are repented.
The sluice, C, is connected by jointed rods, D, to the ends of two long levers, E,
connected so as to form a lever frame, which has its fulcrum upon a beam or
girder, F, fixed across the channel leading to the sluice, C. Between the fulcrum
and the parts of the levers, E, to which the sluice, C, is connected, I connect the
levers by jointed rads, G, to a float, II, which rises and falls with the level of the
water, and which thereby causes the levers, I, to raise the sluice, C, whenever
the water level exceeds a predetermined height. The rods, G, have threaded
parts, J, at their lower ends, to allow of the flat, II, being adjusted by means of
screw nuts, K, to suit the desired normal height of the water surface. A weight, L,
is fixed to the ends of the levers, E, to counterbalance to a greater or less extent
the weight of the sluice and other parts.
In order to prevent the current of water when the sluice is open from moving
the float, II, towards the sluice, or disturbing it, the float is connected by a pair of
rods, M, to a beam, N. placed across the channel with its ends placed in recesses
formed in the side walls.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
.claim is :-
In automatic sluices the combination of a free-roller sluice with a float and with
means for counterbalancing the sluice and other parts to a greater or less
extent, the apparatus being arranged and operating substantially as hereinbefore
described.
