PROVISIONAL SPECIFICATION.
Self Acting Apparatus for Utilising and Regulating Overflow Water
on Tops of Weirs and other places.
ROBERT MARSHALL Iron Works Caledon Co. Tyrone Ireland Mechanic, JOHN
CHARLES SMITH Woollen Manufacturer Caledon County Tyrone Ireland do
hereby declare the nature of this invention to be as follows:-
May be made of iron, or any other suitable material working on pivots and
uprights less than half-height, the under part to overbalance so as to keep down,
and shut; the upper part to raise higher above pivots so that the pressure of
water overbalancing causes valve or gate to open and runing water off to any
required height, opening and closing as the water would rise and fall, and keep
open in case of flood or any excess of water over height required.
The gates or sluices can be made in parts or sections to any suitable or required
width or height.

COMPLETE SPECIFICATION.
Self Acting Apparatus for Utilising and Regulating Overflow Water
on Tops of Weirs and other places.
ROBERT MARSHALL Mechanic, Iron Works, Caledon Co. Tyrone JOHN
CHARLES SMITH Woollen Manufacturer. Caledon Co. Tyrone Ireland 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:-
May be made of iron or any other substitute material working on pivots and
uprights less than half height, the under part to overbalance so as to keep down
and shut, the upper part to rise higher above pivots so that the pressure of water
overbalancing causes valve or gate to open and running water off to any required
height opening and closing so as the water would rise and fall and keep open in
case of flood or any excess of water over height required.
The gates or sluices can be made in parts or sections to any suitable required
width or height.

4. Self-acting apparatus (shown part open).
5. Self-acting apparatus (shown closed).
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
-
(1). By our invention we can save useful water from running to waste over weirs

page_text: or by washes or other places, when there is any need for saving same, and thereby
increase the water power of a river, by preventing the water running to waste
when the mill or works is stopped at meal hours at night or at other times.
(2). Our invention is self-acting and can be set to regulate the height of water
concerned, if there is any danger of the water getting too high, and thereby causing
damage.
We claim, our invention does away with this danger of doing damage, as, if a
fresh or flood came on in the river our self-acting apparatus or safety weir top gate
would open and remain open or partially open as long as the water continued high,
and in no way retard the flow of the water, but when the flood or fresh of water
had subsided to its normal or usual flow or height, or level, then our invention
would again become a water-saving apparatus.
(3). We also claim, by using our invention existing weirs can be lowered
(without causing loss or damage by loss of water to mill owners or other users of
water) so that in time of floods or freshes the water will have less obstruction or
hindrance to clearing off from the flooded lands.
