I, THOMAS BLAKEBOROUGH Hydraulic. Engineer Brighouse Yorkshire do hereby
declare the nature of my invention for DOUBLE ACTING SLUICE VALVES to be as
follows:-
:
This consists of one Sluice working within the other, the Internal Sluice, being
one third the diameter of the External Sluice, and both the Sluices being worked
with one Spindle.
In working it opens first the Internal or smaller Sluice, thus largely reducing
the pressuré upon the External or larger Sluice, and enabling that to be opened
with ease..

Improvements in Double Acting High Pressure Sluice Valves.
THOMAS BLAKEBOROUGH Hydraulic Engineer Brighouse Yorkshire I do hereby
declare the nature of my invention for DOUBLE ACTING HIGH PRESSURE SLUICE
VALVES and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :—
My Invention relates to certain improvements in Sluice Valves to resist high
pressure, and to enable them to be opened and closed easily, and without
concussion in the Mains, and consists of one Sluice working within the other, the
internal Sluice being one third the diameter of the external one, and both the
Sluices being actuated from one Spindle,

The beforegoing being the nature, and object of this Invention, I will now
illustrate how it may be practically applied, and describe a Sluice Valve
constructed according to this invention such as suitable for high pressure water
Mains.
Reference being had to the annexed sheet of Drawings, which are marked with
letters and figures of reference corresponding with those in the following
explanation, like letters being used, to denote like parts, throughout the various
views and figures..
Figure 1 is a sectional elevation of a double-acting Sluice Valve, suitable for
high pressure water purposes, constructed and fitted according to my invention.
Figure 2 is a cross section of Figure 1.
The Sluice Valve illustrated is a double acting horizontal one; (they can be
made to work either horizontal or vertical).
A is the shell or outer case, of Cast Iron with Gun Metal faces.
B is the external or larger Sluice of Cast Iron, with Gun Metal faces outside to
suit those in shell, and inside to suit the internal Sluice.
C is the internal or smaller Sluice of cast Iron, with Gun Metal faces, to which is
attached the Gun Metal Nut E.
D is the Screwed Spindle of Gun Metal.
F is the Worm and Wheel 'gearing for opening and closing the Sluices.
G is the grooved Wheels, which run on the central bar.
H is the flanged ends for bolting to. Mains.
The action of the Valve is as follows When the 'Spindle D. is actuated, the
internal Sluice is opened first, thus largely reducing the pressure upon the larger
Sluice B, and enabling that to be opened with ease, also avoiding concussion in the
Mains, and giving a full clear passage through the Valve the size of the Main.
. Having now particularly described, and ascertained, the nature of..my said
Invention and in what manner the same is to be performed, I declare that what
I claim is
F
First: Actuating the two Sluices with one Spindle, in the manner herein set
forth, and illustrated at Figures 1 & 2 of the accompanying Drawings.
Secondly. Actuating one Sluice within the other, in the manner herein set forth,
and illustrated at Figures 1 & 2 of the accompanying Drawings.
Dated this 2nd day of September 1885.
