PROVISIONAL SPECIFICATION.
Improvements in or connected with Sluices for Water Ways or
Passages.
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 comprises improvements applicable to sluices which are
preferably of the kind described in my Patent Specification No. 3103 of 1874.
When a water way or passage in connection with a dock, or a canal lock, or the
like, is provided with a sluice, it is desirable to have means for shutting off the
sluice chamber to allow of examining the sluice; and for this purpose solid doors
are provided which are let down into grooves constructed for the purpose in the
masonry, at the entrance and exit parts of the sluice chamber. By the present
invention skeleton frames are provided for being let down into the grooves when
the solid doors are removed. The skeleton frames are shaped to exactly fill the
grooves, and to have their inner edges flush with the sides of the passage. The
grooves extend up above the passage as far as required, and an iron lintel is fixed
across at the top of the passage, through a slot in which lintel the skeleton frame
or the solid door is lowered and raised, an enlargement at the top of the frame or
door closing the slot in the lintel when the frame or door is in its lowest position.
Instead of the grooves being in the masonry they may be partly or wholly formed
in the framing of the sluice chamber.
Another improvement is applicable to a staunching bar for preventing leakage
of water along the top of the sluice door when closed. The improved staunching
bar is a horizontal bar of square section but having a narrow projecting strip along
its bottom surface. The bar is retained in a groove formed in an over-hanging
part along the top of the sluice door, having a limited freedom of movement in the
groove. The inside of the overhanging lip of the groove is vertical and planed
and a planed vertical side of the bar bears thereon; and when the sluice door is
closed down, the projecting strip (also planed) along the bottom of the bar bears

bar and the sides of the sluice door fit as closely as conveniently practicable
between the jambs of the doorway; or vertical staunching bars may be applied at
the sides of the sluice door.

COMPLETE SPECIFICATION.
Improvements in or connected with Sluices for Water Ways or
Passages.
I, 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 comprises improvements applicable to sluices which are
preferably of the kind described in my Patent Specification No. 3103 of 1874.

page_text: When a water way or passage in connection with a dock, or a canal lock, or the
like, is provided with a sluice, it is desirable to have means for shutting off the
sluice chamber to allow of examining the sluice; and for this purpose solid doors
are provided which are let down into grooves constructed for the purpose in the
masonry, at the entrance and exit parts of the sluice chamber. By the present
invention skeleton frames are provided for being let down into the grooves when
the solid doors are removed. The grooves extend up above the passage as far as
required and an iron lintel is fixed across at the top of the passage through a slot
in which lintel the skeleton frame or the solid door is lowered and raised.
Another improvement is applicable to a staunching bar for preventing leakage of
water along the top of the sluice door when closed. The improved staunching bar
is a horizontal bar of square section but having a narrow projecting strip along its
bottom surface. The bar is retained in a groove formed in an overhanging part
along the top of the sluice door and has a limited freedom of movement in the
groove.
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 my improvements in or connected with
sluices.
Figure, 1, of the drawings is a sectional plan of a sluice and sluice chamber as
made with my improvements. Figure, 2, is a transverse vertical section of the
same.
Figure, 3, is a transverse vertical section of part of the sluice and the lintel,
drawn to a larger scale.
In these drawings the same reference letters are used to mark the same or like
parts wherever they are repeated.
I provide skeleton frames, A, for being let down into the grooves, B, when the
solid doors (not shown) are removed. The skeleton frames, A, are shaped to
exactly fill the grooves, B, and to have their inner edges flush with the sides of the
passage, C. The grooves, B, extend up above the passage as far as required, and
an iron lintel, D, is fixed across at the top of the passage, through a slot in which
lintel the skeleton frame, A, or the solid door, is lowered and raised, an enlarge-
ment, F, at the top of frame or door closing the slot in the lintel when the frame
or door is in its lowest position. Above the passage, C, the grooves, B, are made
larger than in the passage to allow clearance to the enlargement, F. Instead of
the grooves, B, being in the masonry they may be partly or wholly formed in the
framing of the sluice chamber.
Another improvement is applicable to a staunching bar, G, for preventing
leakage of water along the top of the sluice door, H, when closed. The improved
staunching bar, G, is a horizontal bar of square section but having a narrow
projecting strip along its bottom surface. The bar, G, is retained in a groove in.
an overhanging part, J, formed along the top of the sluice door, H, and it has a
limited freedom of movement in the groove. The inside of the overhanging lip of
the part, J, forming the groove is vertical and planed and a planed vertical side of
the bar, G, bears against it, and when the sluice door, H, is closed down, the
projecting strip (also planed) along the bottom of the bar bears on a planed surface
formed along the lintel, D, or at the top of the doorway frame. The ends of the
bar, G, and the sides of the sluice door, H, fit as closely as conveniently practicable
between the jambs, L, of the doorway. Pins, M, are screwed through the top of
the part, J, of the sluice door to retain the bar, G, in its place.
Vertical staunching bars similarly arranged inay be applied at the sides of the
sluice door.
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 :-
1. In connection with sluices for water ways or passages providing the sluice

page_text: chamber with grooves and lintels for shutting-off doors and with skeleton frames to
fill the grooves when the said doors are not in use substantially as hereinbefore
described.
2. In connection with sluices for water ways or passages, the improved con-
struction and arrangement of staunching bar and parts with which it acts,
substantially as herein before described.
