PROVISIONAL SPECIFICATION.
Improvements in Sluice or Large Valves.
1, JOHN BARR, of The Glenfield Company, Kilmarnock, Limited, East Shaw Street,
Kilmarnock, in the County of Ayr, North Britain, Secretary, do hereby declare the
nature of this Invention to be as follows, that is to say :-
My said Invention has for its object to improve the construction of sluice or
large valves, to diminish their cost and render them less liable to fracture.
In carrying out my Invention I make the body or main shell of the valve box in a
single casting together with a part of the chamber into which the doors or valve
slides are moved when opened. Two opposite valve-seat frames are cast separately
of iron or steel, and each is made with strengthening ribs and with an annular rim
to fit a groove formed for it in the body casting. These seat. frames are entered
into their places through the opening through which the doors or valve slides are
entered and withdrawn, and they are by preference forced into the grooves by means
of an hydraulic press. The seat frames may however be fitted into their grooves
with gunmetal or brass liners to admit of their easy removal when required for the
passage of scraping or cleaning apparatus along the pipes to which the valves are
fitted. There may be a single valve, slide or door or two or more, fitted to work
between the seat frames, the door or doors and the seats on the frames being
provided with gunmetal or brass facings if required. The door or doors may be
moved by screw or rack and pinion gear of any suitable known kind.

COMPLETE SPECIFICATION.
Improvements in Sluice or Large Valves.
I, JOHN BARR of The Glenfield Company Kilmarnock Limited, East Shaw Street,
Kilmarnock, in the County of Ayr, North Britain, Secretary, do hereby declare the
nature of this invention and in what manner the same is to be performed, to he
particularly described and ascertained in and by the following statement, that is
to say-
My said Invention has for its object to improve the construction of sluice or large
valves, to diminish their cost and render them less liable to fracture.
In carrying out my Invention I make the body or main shell of the valve box in a
single casting together with all or part of the chamber into which the doors or valve
slides are moved when opened. Two opposite valve-seat frames are cast separately of
iron or steel and each is made with strengthening ribs and with an annular rim to fit
a groove formed for it in the body casting. These seat frames are entered into their
places through the opening through which the doors or valve slides are entered and
withdrawn, and they are by preference forced into the grooves by means of an
hydraulic press. The seat frames may however be fitted into their grooves with
gunmetal or brass liners to admit of their easy removal when required for the passage
of scraping or cleaning apparatus along the pipes to which the valves are fitted.
There may be a single valve slide or door or two or more fitted to work between the
seat frames, the door or doors and the seats on the frames being provided with
gunmetal or brass facings if required. The door or doors may be moved by screw
or rack and pinion gear of any suitable known kind.

page_text: And in order that my said Invention and the manner of performing the same
may be properly understood I hereunto append two sheets of explanatory drawings
to be hereinafter referred to and showing apparatus made with one modification of
my improvements.
Figure, 1, on sheet, 1, of the accompanying drawings is a longitudinal vertical
section and figure, 2, is a transverse vertical section of apparatus having three doors
or valve slides. Figure, 3, is a longitudinal vertical section of the valve box.
Figures, 4, and 5, on sheet, 2, are a plan and a horizontal section corresponding to
figure, 2. Figures, 6, and 7, are an elevation and a section of one of the valve seat
frames. In these drawings the same reference numerals are used to mark the
same or like parts wherever they are repeated.
The valve box, 8, is made in a single casting which also comprises the chamber, 9,
into which the doors or valves, 10, 11, 12, are moved when opened. Two opposite
valve-seat frames, 13, (one of which is shown separately in figures, 6, and 7) are cast
separately of iron or steel and each is made with strengthening ribs, 14, and with an
annular rim to fit a groove, 15, (figure 3) formed for it in the body casting, 8.
These seat frames, 13, are, before introducing the valves entered into their places
through the opening, 16, (figure 3) through which the valves, 10, 11, 12, are entered
and withdrawn, and they are by preference forced into the grooves, 15, by means of
an hydraulic press. The valves, 10, 11, 12, and the seats on the frames, 13, are
provided with gunmetal or brass facings, 17. Each valve, 10, 11, 12, is moved, in
the usual manner, by means of a screwed spindle, 18, 19, 20, which works through an
internally screwed nut, 21, 22, 23, at the top part of each door. The spindles, 18,
19, 20, pass out through stuffing boxes in a cover, 26, closing the opening, 16, the
outer end of each spindle being squared to receive a key for turning it by.
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 :-
:-
Making the valve box for a sluice or large valve in one casting comprising also
more or less of the chamber into which the doors or valve slides are moved when
open, and fitting valve-seat frames within the valve box, substantially as herein before
described.
