I, HERBERT JOHN HADDAN, of the firm of Herbert & Co., Patent Agents, of
18 Buckingham Street, Strand, W.C. London, in the County of Middlesex, Civil
Engineer, do hereby declare the nature of this invention, a communication to me from
abroad by Louis Lucy Le Breton of Orléans, in the Republic of France, Engineer, to
be as follows:-
This invention relates to a sluice formed with a ball furnished with a foundation
plate to be fixed to the bottom of a basin, pond or reservoir, or any other place, it has
four holes for fastening-bolts to keep it steady and receives at the upper part a crown
which is raised to leave the mud below the level of the plate. The crown is circular,
capable of removal, fitting to the foundation plate by an inner and outer rim adjusted
to an indentation made in the foundation plate for this purpose. A circular bronze
ring or seat placed in the crown receives the spherical ball of cast iron, made larger
than the outflow orifice of the crown, provided at the part where it comes into contact
with the ball with a bronze ring and at its upper part, perpendicular to the axis, with
a ring of cast iron attached to it to connect it with the lever and the intermediate
ring; a copper ring connects the ball to a lever.
A metal lever of varied curves, moving on hinge joints on a fixed point at its end,
is used to carry the ring and the ball at the axis of the orifice.
A chain of metallic cord fastened to the end of the lever and suspended
to a convenient place is used for operating the sluice ball and for regulating the
distribution.
The ball sluice is joined to an over-flow weir, by a cast-iron pipe conduit resting at
the bottom of the reservoir on a cast-iron support and attached thereto by bolts.
The pipe has a rounded orifice at its upper end, four winglets of cast iron placed in
quadrangular fashion is cast on its circumference, intended to receive a cast-iron hood,
at its inner part there is a connecting flange to connect with another length of a pipe.
A hollow hood of cast iron rests upon the winglets for the purpose of diverting the
direct fall of water.
A small cap or bell of cast iron surmounts the hood with an aperture at its lower
circular part in order to admit into the weir pipe the necessary air for the circulation
of the water which escapes from the reservoir.
Dated this 31st day of October 1889.

Improvements in Sluices.
1 HERBERT JOHN HADDAN of the firm of Herbert & Co., Patent Agents of
18 Buckingham Street, Strand W.C. London, Civil Engineer, do hereby declare the
nature of this invention, a communication to me from abroad by Louis Lucy Le
Breton, Engineer, of Orléans, in the Republic of France, 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 sluices and reference being made to the accompanying
drawing:
Figs. 1 and 2 represent in elevation and plan the improved sluice formed with a
ball c and crown b and furnished with a foundation-plate a to be fixed to the bottour
of a basin, pond or reservoir or any other place. The foundation-plate has four holes
for fastening bolts to keep it steady and receives in the upper-part a crown b, which

is raised to leave the mud below the level of the plate. The crown 6 is circular
capable of removal, fitting to the foundation plate by recessed rim and flange adjusted
to an indentation made in the foundation plate for this purpose; a circular bronze
ring or seal ¿¹ placed in the crown by receives the spherical ball of cast iron, made
larger than the outflow orifice of the crown and which also may be provided at the
part where it comes into contact with the crown with a bronze-ring ². The said
ball c is provided at its upper part perpendicular to the axis with a ring or eye of cast
iron attached to it to connect it with the lever by means of an intermediate ring or
link, preferably a copper ring.
c. is a hinge-joint standard made of cast iron grooved at its lower part and cast
direct to the plate a; it receives the lever, which rotates on a bolt traversing said
hinge-joint, and secured with a pin at its end.
is a cast iron lever of varied curves moving on hinge-joints on a fixed point at its
end and is used to carry the ring d with the ball e at the axis of the orifice; it is of
indefinite length. The curve & following a fixed line larger than that of the ball and
close to the axis and the hinge-joint is arranged in such a manner as to hold the ball
upon the opening of the sluice to completely open the orifice of the water outlet ;
the small catch or butt fixed to or cast on the lever behind the hinge-joint close to
it, limits the course of the lever.
Σ is a chain or metallic cord fastened to the end of the lever g and suspended to a
convenient place for operating the sluice ball and for regulating the distribution to
supply a variable quantity of water.
Separate designs of the separate parts belonging to the sluice are: 1) the ball c
(Fig. 2") shown in half section for the purpose of giving an idea of the fitting of the
bronze-mounting; so also with the design of the crown with ring shown in
Fig. 2b as an elevation in half-section and a plan; 2) this same ball is represented in
Fig. 3 with a mounting in india-rubber which can also be taken off, kept at the lower
part of the ball by a ring and a tightening screw, which fits likewise to the spherical
part in contact. This ball may also be used with a cast-iron crown without bronze-
mounting, these therefore constitute two systems of balls and crowns.
The Figs. 4, 5 and 6 are respectively a side elevation of Fig. 5 partly in elevation,
.partly in section; a half elevation and half section; a plan corresponding to Fig. 5 ;
Figs. 7.and S. represent in half elevation and half section and in plan the upper part
of the discharge-pipe.
The ball-sluice is joined to an over-flow weir by a cast-iron pipe n resting at the
rbottom of the reservoir on a cast-iron support o attached by bolts.
The pipe J has a rounded orifice at its upper end with four wings i, 1, 1, 1, of
cast iron placed in quadrangular fashion as cast on its circumference, intended to
support a cast iron hood l, at its lower part there is a connecting flange to connect
with another length of a pipe. The hollow hood rests upon the wings i, i,,,
for the purpose of diverting the direct fall of water and to arrest at the surface of the
water level foreign matter floating on the water, which would otherwise be drawn into
the pipe.
A small cap or bell m of cast iron surmounts the hood with an aperture at its lower
circular part to admit into the weir pipe the necessary air for the circulation of the
water, which escapes from the reservoir."
Fig. 9 is a vertical section on line AB Fig. 10 of a ball-sluice with its connection-
With this
pipe. Figs. 11 and 12 are transverse sections on lines C D and E F.
variation based upon the same principle as above the ball is hollow; besides it is
provided at its, upper end with a boss pierced with a hole to engage therein a pin in
order to connect it with the lever. For this purpose the latter is provided with a fork,
the branches of which are pierced with a hole for the passage of the pin. By placing
the boss into the fork with the hole to correspond with those of the branches and
engaging the pin therein, the ball is then connected with the operating lever;, which
turns in the same manner as above described.
Figs: 13; 14 and 15 show in elevation, plan and longitudinal section another
arrangement of a ball sluice with pipe.

page_text: The ball has at its upper part an eyelet into which one inserts the hook of a vertical
rod perforated on its length and terminating by another hook after having traversed
the height of the support.
To this last hook is attached a chain the last link of which has a pin intended for
insertion into one of the holes of the rod,-when one raises the ball to a certain height
to allow the flow of more or less water, two guides or ears are cast to the body of the
ball they are of medium height, diametrically opposite each other and resting
against rods to direct the ball always vertically when it is raised.
Figs. 16, 17, 18, 19 are a longitudinal section on line 1 J, a plan, a transverse
section on line K L and a transverse section on line M N of another arrangement
of the ball sluice. The neck of the tube has two flanges to which are screwed two
rods connected above by a cross-piece through the center of which passes the rod
perforated with holes lengthwise and to which is hooked the ball the latter having
also two cars, which, engaged in the large rods lateral to the ball, serve to guide
the same when it is raised and maintained at various heights by means of the pin,
which terminates the chain hooked to the upper part of the central rod.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, I declare what 1
claim is:
1) The combination with the pipe having the crown of the ball-sluice c with lever
or equivalent for lifting and replacing the same substantially as herein described and
illustrated.
2) The combination of the pipe crown b, the ball-sluice c, the overflow pipe J with
hoods and m, the whole connected together for the purpose set forth.
