Works, Manchester Road, Bradford, in the County of York, Brass Founders, do
hereby declare the nature of this invention to be as follows
-
The object of this invention is to obtain a Steam, Water, or Gas tight fullway
Valve
We accomplish our object by forming the valve with a vertical face on the opposite
side to the pressure, the side of the same to the pressure is formed as an inclined
plane, the seating for the valve is faced on the opposite side of the pressure and has
an inclined plane on the pressure side corresponding to that of the valve
Into the face of the valve we form a circular recess, and pack the same with
asbestos, or, into the face of the seating of the valve, we insert this packing The
valve is actuated by a quick screw passing through the same in a vertical direction
moved by the ordinary hand wheel-when the valve 18 shut, the metal surface of the
valve is brought in tight contact with the recessed asbestos face of the seating, or
vice versa
When the valve is opened the first turn of the handwheel, or the screwed spindle,
the face of the valve is released from the face of the seating, and the valve is thus
raised clear the face of valve and seating are only tight on the last turn of the
spindle in closing the valve, when a Steam, Water, or Gas tight joint is secured

page_text: We, WII LIAM HARTLEY, and WILLIAM HUGHES ROSE, both of Caledonia Brass
Works, Minchester Road, Bradford, in the County of York, Brass Founders, 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
stitement
The object of this invention is to obtain by a simple arrangement and combination
of parts fullway valve suitable for steam, water, or gas, and consists in forming one
side of the valve with a vertical face, by preference on the opposite side to that of
the pressure, the opposite side or face of the valve on which the pressure is, being at
an angle or incline with the front, the seating in the valve block having corresponding
faces formed therein
In the vertical face of the valve is formed a circular recess into which is inserted a
ring of asbestos or other suitable flexible packing or soft metal such as that known as
"white metal," with which on being pressed tight against the facing in the valve
bloch, a joint is made, the valve being actuated by a quick pitched screw passing
through the same in a vertical direction, and operated by a hand wheel or the like-
In lieu of placing the flexible or metal packing in the valve, a groove may be formed
in the seating or face of the valve block for the reception of the same, in which
case the valve is prepared with a plain surface
In order that our invention may be more fully understood, we will further describe
the same by making reference to the accompanying sheet of drawings in which,
Fig 1 represents a view of a fullway valve constructed according to our invention,
a portion of the same being in section for the purpose of better illustration
Figs 2 and respectively represent a front view of the valve, and a section of the
sanie
Figs 4 and 5 similar views, showing the packing secured in a modified manner,
and,
Fig 6 a section through the valve showing another modification
The side A of the valve V which is not exposed to the pressure, we form vertical,
and cut in the same a recess B the outer circumference of which is undercut, and
into the said recess we place a ring of asbestos, or other suitable flexible packing or a
ring of "white metal" ( which is by preference secured therein by a ring D having
the outer circumference cut to an angle, so that when placed in position, the before
mentioned recess is somewhat V-shaped for the reception of the packing C the
ring D being held in the said recess by two or more screws E by which the
packing C is effectually secured therein
The opposite side of the valve at F where the pressure is, we form at an angle or
incline with the face A so that the valve V is somewhat wedge shaped, and cut at F.
to accurately fit the angular seating (3 of the valve blook

or
The packing C may be secured to the valve V as shown by Fig 5 in which case
a similar recess is cut for the reception of the packing which is forced into the
by pressure, and retained therein by the undercuts without the aid of the ring
the packing C may be secured to the vertical face of the valve V by a modified
arrangement as shown by Fig 6 according to which method, a ring H is used for
retaining the packing in position, the said ring being cut to fit the turned
circumference of the valve V
It will be obvious that a groove may be cut in either or both of the faces in the
valve block and packing inserted therein similar to that before described, or that in
addition to packing being inserted on one side only of the valve V by making the
inclined portion at F bronder than shown on drawing, groove may be cut therein
and packing inserted and secured by any of the methods hereinbefore described
Hiving now particularly described and ascertained the nature of this our inven-
tion and in what manner the same is to be performed, we declare that what we
claim is
-
The general arrangement and combination of valves having the interior constructed
substantially in the manner shown and described, in which one or more rings of
flexible material, or white metal is, or are inserted therein for the purpose and in the
manner as hereinbefore described
