Improvements in Stop and Through Way Valves.
We, TEMPLER & RANOE LIMITED and JAMES PHILIP RANOE, all of Vicarage Road,
Rugby, in the County of Warwick, Engineers, do hereby declare the nature of
this invention to be as follows:-
This invention relates to improvements in connection with stop and through
way valves for steam, water, gas and for like purposes, the object being to produce
a simple, easily repaired, and efficient through way clear passage stop or shut off
valve in which there shall be double wedging or closing surfaces by the action
of the screw down spindle or lever for controlling such valve.
In carrying our invention into effect when constructing a stop valve for use in
shutting off steam or water and for manipulation by means of the ordinary hand
wheel and spindle, we form the body of the valve as a T piece, the flanges on the
through way passage being made at either end to suit the form of flange or coupling
connection to which the valve is to be attached. On the upper portion of the
valve body we form a flange and secure on to it a casing upon which we form a
stuffing box for the spindle to pass through the stuffing box being provided with
gland tightening screws or attachments constructed in any ordinary manner.
We provide within the opening of the valve body bushes or rings of gun metal
or other suitable material which shall form a working face against which the
valve discs can be made to seat. The valve discs we make in pairs coupled together
by means of a cradle casting or frame into which the bodies of the valve discs can
enter so that when the cradle is raised or lowered the two valve discs are raised and
lowered also.
Upon the lower portion of the valve body or chamber into which the valve discs
enter we provide a double wedge like ridge piece of circular, segmental, or spare
configuration to suit and receive the similarly formed conical faces on the inner
portions of the valve discs, the cone surfaces being so arranged that when the
valve discs are thrust downwards they slide one upon the other and so cause the
dises to be forced outwards and to wedge against the bearing face of the bushes
within the valve passages.
Within our cradle carrying the two valve discs we place the end of the
spindle having a T shaped head preferably upon it or attached to it, the inner
portion of which is conical on both sides to suit the shape of the coned face on
each of the valve discs so that when the screw spindle is driven down the conical
end of the spindle forces apart the valve faces at the upper end while the conical
bridge piece of the cradle or fixed seat in the centre of the valve chamber at the
lower end also forces outwards the valve discs.
We introduce a gap or opening in the bridge piece of the cradle connecting neck
or shoulder for receiving the spindle and a nut for causing it to raise and depress
the cradle and its valve face. To assist the action of the screw spindle and to take
off the weight of the valve, we may sometimes introduce a spring between the
collar, which we form upon or attach to the spindle and cause the spring to press
against the lower surface of the bridge piece neck.
We make the central chamber of the valve of a capacity and size to admit of the

page_text: whole of the valve discs and connections to be easily withdrawn when the upper
stuffing box cover is removed.
We modify the form of our faces, and the method of securing them in the
cradle together with the shape and connections of the spindle and its wedging end
to suit the type of the valve which is to be constructed and the purposes for
which it is required.
We may actuate our spindle by means of a hand wheel and screw and nut for
controlling its movement or by lever or rack and pinion, as employed for similar
type of valves at present constructed in the ordinary manner.

We, TEMPLER & RANOE LIMITED and JAMES PHILIP RANOE, all of Vicarage Road,
Rugby, in the County of Warwick, Engineers, 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 statement:-
This invention relates to improvements in connection with stop and through
way valves for steam, water, gas and for like purposes, the object being to produce
a simple, easily repaired, and efficient through way clear passage stop or shut off
valve in which there shall be double wedging or closing surfaces by the action
of the screw down spindle or lever for controlling such valve.
Our invention is illustrated by the accompanying drawings in which
Figure 1 is a sectional elevation of one form of our valve.
Figure 2 is a cross section of Figure 1, and
Figures 3 and 4 represent a modified form of our invention.
In carrying our invention into effect when constructing a stop valve for use in
shutting off steam or water and for manipulation by means of the ordinary hand
wheel and spindle, we form the body of the valve as a T piece, the flanges on
the through way passage being made at either end to suit the form of flange or
coupling connection to which the valve is to be attached. On the upper portion
of the valve body we form a flange a and secure on to it a casing upon which we
form a stuffing box for the spindle c to pass through, the stuffing box being
provided with gland tightening screws or attachments constructed in any ordinary
manner.
As shown in Figures 3 and 4, we provide within the opening of the valve body
bushes or rings d of gun metal or other suitable material which shall form a
working face against which the valve rings e can be made to seat. The valve discs /
we make in pairs coupled together by means of a cradle p, casting or frame into
which the bodies of the valve discs can enter so that when the cradle is raised
or lowered the two valve discs are raised and lowered also.
Upon the lower portion of the valve body or chamber into which the valve discs
enter we provide a double wedge like ridge piece g of circular, segmental, or square
configuration to suit and receive the similarly formed conical faces h on the inner
portions of the valve discs, the cone surfaces being so arranged that when the
valve discs are thrust downwards they slide one upon the other and so cause the
discs to be forced outwards and to wedge against the bearing face of the
bushes within the valve passages.

page_text: Within our cradle carrying the two valve discs we place the end of the
spindle e having a T shaped head fl preferably upon it or attached to it, the inner
portion of which is conical on both sides to suit the shape of the coned face on
each of the valve dises so that when the screw spindle is driven down the conical
end of the spindle forces apart the valve faces at the upper end while the fixed
seat g in the centre of the valve chamber at the lower end also forces outwards the
valve discs /.
We introduce a gap or opening in the bridge piece connecting neck or
shoulder of the cradle for receiving the spindle and nuts for causing it to raise
and depress the cradle and its valve face. To assist the action of the screw spindle
and to take off the weight of the valve, we sometimes introduce a spring between
the collar s, which we form upon or attach to the spindle and cause the spring to
press against the lower surface of the neck of the bridge piece p.
As shown in Figures 1 and 2, upon the end of the spindle sleeve e we screw or
secure the end of a wedge shaped carrier f the lower portion of the carrier being
formed as a double arm to enter under pins or lugs which are attached to or
formed upon the inner sides of each valve disc block . To guide the disc blocks
we prefer to form grooves m or projecting ribs on the valve body into which ribs n
or channels on the valve blocks may engage, the guiding ribs fitting loosely into
the grooves to admit of the lateral movement of the faces when forced apart by
the downward motion of the spindle which urges the tapered end of the carrier f
to enter between the tapered surfaces of the valve blocks while the tapered ridge
piece g forces outwards the lower portions of the blocks against the valve seats d.
We make the central chamber of the valve of a capacity and size to admit of
the whole of the valve dises and connections to be easily withdrawn when the upper
stuffing box cover is removed.
We modify the form of our faces, and the method of securing them in the cradle
together with the shape and connections of the spindle and its wedging end to suit
the type of valve which is to be constructed and the purposes for which it is
required.
We may actuate our spindle o by means of a hand wheel and screw and nut for
controlling its movement, or by lever or rack and pinion, as employed for
similar type of valves at present constructed in the ordinary manner.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is;-
1. The improved stop and through way valve having independent valve faces
or dises with tapered or conical inner surfaces against which similarly tapered
or conical surfaces arranged or carried upon the controlling spindle and upon
the valve body may act to force the discs outwards, substantially as hereinbefore
described, and as illustrated in the accompanying drawings.
2. In a through way or stop valve the combination of a valve body or casing
having a tapered ridge piece or lower wedge block attached to or arranged thereon,
with two independent valve dises or moving faces carried upon the end of a
controlling spindle which thrusts the faces apart when they are in their lower
position and resting upon the ridge piece within the valve body, substantially
as herein before described.
