page_text: LETTERS PATENT to George Thomas Blundell, of the Firm of Blundell Brothers,
of Limehouse, in the County of Middlesex, Engineers and Coppersmiths, and
Edwin William De Rusett, of Blackheath, in the County of Kent, Civil
Engineer, for the Invention of "IMPROVEMENTS IN VALVES FOR SOIL PIPES,
SCUPPERS, OR OTHER DISCHARGE PIPES IN SHIPS OR OTHER VESSELS."
ealed the 2nd November 1877, and dated the 5th May 1877.
PROVISIONAL SPECIFICATION left by the said George Thomas Blundell
and Edwin William De Rusett at the Office of the Commissioners of Patents
on the 5th May 1877.
GEORGE THOMAS BLUNDELL, of the Firm of Blundell Brothers, of Limehouse, in
the County of Middlesex, Engineers and Coppersmiths, and EDWIN WILLIAM DE
RUSETT, of Blackheath, in the County of Kent, Civil Engineer. "IMPROVEMENTS IN
VALVES FOR SOIL PIPES, SCUPPERS, OR OTHER DISCHARGE PIPES IN SHIPS OR OTHER
VESSELS."
Our Invention has reference to valves which are made to slide like a sluice valve
for the purpose of closing the aperture between the ship's side and the clap valve,
or other form of storm valve employed in soil pipes, scuppers, or other discharge
pipes in ships or other vessels.
And the Invention consists,—
Firstly. In housing or shrouding the screw, by which the said slide or sluice valve is
worked within a sleeve on the back of the valve, whereby it is protected from the
wash of the sea or other injury. The valve itself may be made in any manner
desired, but we prefer to form it with wedges at the back, which as the valve is
being lowered work against inclined guides in the valve case, so that the valve
is forced against its seat, and thus properly closed. The said sluice or slide valve
is placed sufficiently near the storm valve (when such is used) to allow the latter
to be removed, and replaced when required through the outlet aperture in the
ship's side.
Secondly. In order to allow the spindle of slide or other valves used for
closing discharge pipes (whether provided with a screw. or not) to be operated upon,
regardless of structural details of the ship, that is to say, whether or not a ship's
Price d

page_text: stringer, butt, strap, or other part comes in the direct line of the spindle, or to
enable the valve and spindle to be fitted, so as to suit the varying bevils of such a
structure as a ship's side, we introduce a universal joint in the spindle, so that its
upper part may be inclined at any necessary angle; this universal joint may be in
any convenient position above the stuffing box through which the spindle passes to
the valve,
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said George Thomas Blundell and Edwin William De Rusett in the Great
Seal Patent Office on the 5th November 1877.

the County of Middlesex, Engineers and Coppersmiths, and EDWIN WILLIAM DE

Our Invention has reference to valves which are made to slide like a sluice valve
for the purpose of closing the aperture between the ship's side and the clap valve,
or other form of storm valve employed in soil pipes, scuppers, or other discharge
pipes in ships or other vessels.
Our said Invention will be fully understood on reference to the accompanying
Drawings, in each of the Figures of which said Drawings the same letters of
reference indicate the same or corresponding parts.
Figure 1 is a vertical section of our improved valve.
Figure 2 is a section, one half through the line A, B, and the other half through
the line C, D, of Figure 1, the slide or sluice valve being shewn in its lowered or
closed position in the latter half section only.
Figure 3 is a section through a line E, F, of Figure 1, with the slide valve
lowered.
Figure 4 is a plan of the universal joint we prefer to employ.
Figure 5 shews an arrangement of placing the storm or clap valve in the side of
the sliding valve box or chest.
Figures 6 and 7 are views of modified arrangements.
a represents the ship's side; and b, a soil or discharge pipe; b¹, valve box or
chest; c is the clap or storm valve resting against its seating or face d; this valve
is carried by the plates e, e, one of which plates e, e, only is shewn in Figure 2, to
which it is connected or hinged hy means of lugs f, f, and pins g, g. The plates e, e, are
secured in their places in Figures 1 and 2 by screws 1, h, h, which screw into the
door i; but in Figure 5 the lugs f, f, are shewn cast with or permanently fixed to
the door i. k is the slide or sluice valve, which is raised or lowered by means of the
screw ; this screw in Figures 1, 2, and 3 is shewn housed or shrouded within a sleeve
m on the back of the valve k (this housing of the screw 7 is best seen in Figure 3),
so that it is protected from the wash of the sea or other injury. The spindle of the
screw works in a stuffing box, as seen at n in Figure 2; or in place of the stuffing
box there may be a conical metal joint, as shewn at o, Figure 1. p, p, are wedges at
the back of the valve k, which, as the valve is being lowered, work against
inclined guides q in the valve case, so that the valve is forced against its face or
seating r. It will be seen that the valve k is sufficiently near the storm valve c_to
allow the latter to be removed and replaced when required through the outlet
aperture in the ship's side when the valve k is up; or the valve c may be removed
by taking off the door i. s is the universal joint employed, as before described; it
connects the spindle of the screw 7 with the upper spindle or continuation t, and
allows this spindle to be inclined at any angle, which may be necessitated by the
structural details of the ship.

page_text: The universal joint employed may be of any suitable kind, and it may be placed
at any convenient position above the stuffing box n (Figure 2) or joint o
(Figure 1).
In the arrangement shewn in Figure 5 the storm or clap valve c is shewn at the side
of the box or valve chest b¹, the sluice valve k being at the front, as in Figure 1. The
screw 7, which works the valve k, works through a tapped hole u in the cover of the
valve caso, and is protected by a long neck v with stuffing box n at the top. 8 is
the universal joint. In this arrangement the screw and the universal joint rise
with the valve k, but it is evident that the housed screw arrangement (shewn in
Figures 1, 2, and 3) may be used with this valve arrangement.
Figure 6 shews another method for operating the valve k, by passing the spindle
of the scrow through a bracket or standard w; in this case also the screw and
universal joint rise with the valve k.
Figure 7 shews an arrangement in which the screw works through a tapped
bush in a wheel x; this wheel does not rise with the valve k, but the screw land
universal joint rise with the valve. We also raise or lower the valve k by a rack
and pinion, levers, and rods, or rods only, as are usual for operating on sluice valves,
which are woll known methods, but no claim is made to the arrangements shown in
Figures 6 and 7.
Having now described the nature of our said Invention, and in what manner the
same is to be performed, we declare that we claim the mode or modes herein-before
described and represented in Figures 1, 2, 3, and 5 of the Drawings hereunto
annexed, of applying slide or sluice valves to soil pipes, scuppers, or other discharge
pipes of ships or vessels, as and for the purpose described.
In witness whereof, I, the said Edwin William De Rusett, for myself and on
behalf of the said George Thomas Blundell, have hereunto set my hand and
seal, this Third day of November, One thousand eight hundred and seventy-
seven.
