IMPROVEMENTS IN VALVES
Year: 1884

page_text: I ROBERT WRIGLEY of Rosa in the North Western Provinces in the East Indies
do hereby declare the nature of said Invention for "IMPROVEMENTS IN VALVES 籍
to be as follows:-
My Invention has for its object to so construct valves that they and their
Beatings can readily be rearranged when worn so as to give a tight closure without
the necessity for providing parts additional to those originally contained in the
apparatus. According to my said Invention I make the valve of a ball or equi-
valent shape with a number of screw sockets or equivalent attachments formed
therein or provided thereon in such a position that a spindle can be attached to
either of them in such a manner that different portions of the valve can be
presented to the valve seatings. The valve casing is provided with an opening by
which the valve may be inserted and removed and this opening may be closed by
a plug or cover or it may form one of the water ways The water ways and also
the opening which is covered by the top or lid of the valve are furnished on their
inner parts with seatings so that either the one or the other can be used for the
valve to seat itself upon. When the valve becomes worn its spindle is removed
and screwed into or fixed to another of the screw sockets or attachments by which
means a fresh portion of the valve is presented to the seat. Whon the seat becomes
worn the valve casing may be turned into such a position that another seating is
presented in the position to receive the valve the opening containing the worn
seating becoming one of the water ways to or from the valve or the opening closed
by the cover of the valve.
There being no wings webs or feathers to the valve and seats the valve is not
liable to become fixed or clogged. The valve may be arranged as a lift valve or ball
valve or safety or relief valve or as a retaining valve or stop valve. The passages
through the valve casing may be furnished with valve seatings at their exterior so
as to afford renewable seatings to be used for the seating of an external safety
valve. In this case the opening or openings which are not in use for the valve
inlet and outlet may have a gauge or gauges attachod.
I prefer to make the valve with six renewable faces and the casing with four
passages and seatings as these will I believe be found the most convenient numbers
in practice.

I ROBERT WRIGLEY of Rosa in the North Western Provinces in the East Indies
do hereby declare the nature of my invention for "IMPROVEMENTS IN 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 has for its object to so construct valves that they and their
seatings can readily be re-arranged when worn so as to give a tight closure
without the necessity for providing parts additional to those originally contained
in the apparatus.
And in order that my said Invention may be fully understood I shall now
proceod more particularly to describe the same and for that purpose shall refer to
the several figures on the annexed sheets of Drawings the same letters of reference
indicating corresponding parts in all the figures.
Figure 1 is a vertical section of a valve casing and valve constructed according
to my Invention and Figure 2 is a view at right angles thereto the valve
casing only being in section. The other figures are modifications as hereinafter
described.
According to my said Invention I make the valve A of a ball or of an equivalent
shape with a number of renewable faces and if necessary also with a number of
screw sockets a or equivalent attachments formed therein or provided thereon in
such a position that a spindle B can be attached to either of them in such a manner
that different portions of the valve can be presented to the valve seatings C. If
desired the spindle B instead of being fixed to the valve may be fixed to the
casing or cover and work in guiding recesses in the valve. The valve casing D is
provided with an opening by which the valve may be inserted and removed and
this opening may be closed by a plug or cover E or the said opening may form one
of the water ways. The water ways F and also the opening which is covered by
the top or lid G of the valve (which top or lid may be provided with a guide g for
the valve spindle) are furnished on their inner parts with seatings C so that either
the one or the other can be used for the valve A to seat itself upon. When the
valve becomes worn its spindle B is removed and screwed into or fixed to another
of the screw sockets or attachments a by which means a fresh portion of the valve A
is presented to the seat C that may be in use. When this seat C becomes worn the
valve casing D may bo turned into such a position that another Heating C is
presented in the position to receivo the valvo A the opening containing the worn
seating upon which the valve previously rested becoming one of the water ways to
or from the valve or the opening closed by the cover of the valve.
There being no wings webs or feathers to the valve and seats the valve is not
liable to become fixed or clogged. The valve A may be arranged as a lift valve or
ball valve or safety or relief valve or as a retaining valve or stop valve. Figure 3
represents the valve arranged as a weighted safety relief or lift valve and Figure 4
shews it arranged as a spring safety relief or lift valve. Figures 5 and 6 show it
adapted as a screw-down valve Figure 7 illustrates it arranged as an adjustable
lift valve and Figure 8 shews it arranged as a simple ball or retaining valve the

page_text: spindle B in this case being dispensed with. The passages through the valve
casing may be furnished with valve seatings O at their exterior as shown in
Figures 8 and 9 so as to afford renewable seatings to be used for the seating of an
external safety valve as illustrated in the said Figure 9. In this case the opening
or openings which are not in use for the valve inlet and outlet may have a gauge
or gauges attached as indicated at m Although the valve may be a sphere if
desired I prefer to make it with six renewable faces and the casing with four
passages and seatings as these will I believe be found the most convenient numbers
in practice.
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
First-Providing valves with a number of faces and with a number of sockets
or attachments for the fixing or reception of the valve spindle or guide substantially
as bereinbefore described.
Second: Providing valves with a casing having the passages therethrough
provided with seatings which can be brought in position to form a fresh valve
seating when the original seating becomes worn substantially as hereinbefore
described.
Third: In valves the combination of a valve proper having several faces which
can be brought into position to rest on the seating as required with a casing
having the several passages therethrough provided with seatings substantially as
and for the purpose herein before described.
Fourth-The several arrangements or constructions of valves hereinbefore
described and illustrated by the several figures of the accompanying drawings.
