PROVISIONAL SPECIFICATION.
Improvements in Connections and Valves for Warming and other
Purposes.
I, JOHN KING, Benson Street, Liverpool, Engineer do hereby declare the nature
of this invention to be as follows:-
This invention relates to certain improvements to valves and connections, for
warming and other purposes; and has for its object the construction of the same in
such a manner that they, are of full bore and give the least obstruction in the
passage, and can be closed by a half turn of a hand wheel, or other suitable
appliance; they maintain equality of pressure, prevent a vacuum being formed,
when used for steam, avoid freezing, are easier to fix and make a better joint.
The body may be of cylindrical, or other, form hollow in construction, having
inlet & outlet ports, or passages in the usual manner. On the lower portion of
the internal face of the body is a flange of suitable proportion extending, more or
less, around the inside of the body. The upper part of the body is cut away on its
internal face, & into it is screwed, or otherwise fixed, a cap, not fitting close down
at its lower extremity, so that a seating, or recess, is formed around the internal
face of the body, at the lower edge of the cap. The cap will have an aperture
through it, in the centre, coned out at its lower end.
The end of the side port, or branch way, may be slightly recessed to receive an
annular ring of compressed fibre, white metal, or other suitable substance, which
will act as a packing on screwing up the union, or the compressed fibre or packing
may be fixed to the end of the union, as hereinafter described, or the end of the
side port, or branch way, may be coned to receive the conical end of the union.
Fitted inside the body is a hollow plug, which can be revolved, and may be
either circular, a segment of a circle, or of such other form as circumstances may
require, and which may be made either of cast, or sheet, metal, or any metallic or
other suitable substance. The plug is provided, at its base, with a stud, or stop,
which coming in contact with the flange on body, hereinbefore described, acts as a
stop in each direction, left or right respectively.
The plug is provided on one side with a port, or passage, corresponding with the
port, or branch way, on the body; on the opposite side is made a veut of necessary
size for the purposes, when an apparatus, or arrangement, is cut off by closing the
valve, of maintaining equality of pressure & preventing a vacuum being formed on
cooling down, & for supplying a sufficiency of steam, or other fluid, to maintain a
temperature above 32° Fahr. in that portion of the apparatus, or appliance, so
cut off.
The plug is sealed at its highest extremity with a disc of larger size, either loose,
engaged or attached thereto, and this disc working, or fitting in, or on, the seating,
or recess, provided on the upper part of the body, as hereinbefore described, forms
a water tight joint.
In the upper edge of the plug recesses may be formed, or projections arranged,
to engage the lower end of the spindle & turn the plug, or on the disc a projection,
hollow or otherwise, may be provided with recesses, or projections, and to which
the spindle may be engaged. Between the disc & the conical portion of the spindle,
hereinafter described, a spiral, or other, spring may be placed to give such a

page_text: pressure as to keep the disc, & also the conical portion of the spindle, on their
respective seatings, thus rendering the valve self packing.
The spindle passes thro the aperture in the cap, which is more or less conical, &
is provided with a conical portion to correspond with the conical portion of cap,
hereinbefore described. The hollow plug is moved by means of the spindle which
engages, or is connected, with either the projection on the disc, the studs, or the
recesses on the plug; & on the top of the spindle is fixed a hand wheel, or other
suitable appliance, by which the valve can be opened or closed at half a turn.
The aperture in cap, where the spindle passes thro, is closed externally with a
hollow gland nut, or in such other way as may be desirable.
The union is of the ordinary kind, fitted with union nut, but the end may be
recessed and an annular ring of compressed-fibre, white metal, or other substance,
fitted into it to act as packing, or the end of the union may be made conical
externally, to correspond & fit into the coned end of the branch way of the valve,
either of which, when brought in contact with the branch way of the valve by the
connecting nut, make a tight joint.
The inside of the tail, or connecting piece, of the union has on its internal face
two flanges, on opposite sides, so that, by inserting a bar, key, or other arrangement,
the union may be easily & satisfactorily screwed up.

Improvements in Connections and Valves for Warming and other
Purposes.
I, JOHN KING, of Benson Street, Liverpool, in the County of Lancashire,
Engineer, 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 has reference to the manner in which I construct improved valves
and unions for use in connection with warming and other appliances in such a
manner as to allow of a full bore, or passage, through them and to give the least
obstruction in the passage, and to close by a half turn or less of a band wheel or
other suitable appliance; to maintain equality of pressure; to prevent a vacuum
being formed when used for steam; to prevent freezing; and to be more easily
fixed.
In the accompanying sheet of explanatory drawings ;-
Fig. 1 is a sectional elevation of my improved valve and union.
Fig. 2 is a sectional elevation of a method of packing, or preventing leakage at
the stem, or stock, of the valve by means of a compressed fibre, or any other
suitable, washer, retained on its seat, by means of a spring, or any other attachment,
or contrivance.
Fig. 3 is a sectional elevation of a method of packing, or preventing leakage at
the stem, or stock, of the valve, by means of a screw, or other guide, which forces
the conical portion of the stock against a seat.
Fig. 4 is a sectional elevation shewing a method of revolving the plug of the
• valve by means of a projection on the spindle which engages in a slot cut in the
aforesaid plug.
Fig. 5 is a sectional elevation shewing a method of revolving the plug of the
valve by affixing the spindle to an attachment in the centre or interior of the
aforesaid plug.
Fig. 6 is a sectional elevation shewing a method of making the plug by slotting
out a portion in order to give a spring to the plug, and with a slot for engaging
with a projection on the spindle for revolving the plug.

page_text: Fig. 7 is a sectional elevation of a method of forming a union in which the joint
is made by means of a conical projection and recess.
Like letters indicate like parts where they appear.
In carrying my invention into effect when constructing my improved valve and
union I make the body A of cylindrical or other form, hollow in construction,
having an inlet port B, and an outlet port C. On the lower portion of the internal
face of the body A, is a flange D, of suitable proportion, extending, more or less,
around the inside of the body. The upper part E, of the body A, is cut away on
its internal face, and into it is screwed, or otherwise fixed, a cap F, not fitting
close down at its lower extremity, but so that a seating, or recess G, is formed
around the internal face of the flange, in, and near the top of, the body, at the
lower edge of the cap F.
The cap F, is made with an aperture H, through it, in the centre, the aperture
being coned out at its lower end; or recessed to receive a suitable washer.
The end of the side port of the valve, or branch way C, may be slightly recessed
to receive an annular ring of compressed fibre, white metal, or other suitable
substance, which will act as a packing on screwing up the union V, the end of the
union V, being coned or tapered to receive it, or the compressed fibre, or packing,
may be fixed to the end of the union V, as shewn at J, as hereinafter described,
and the end of the port C, being coned, or tapered, to receive it, or the end of the
side port, or branch C, may be coned to receive the conical end of the union, as
shewn at Y in Figure 7, and the end of the union V, may be made conical, or
tapered, as shewn at Y, in Figure 7, to receive the coned, or recessed, end of the
port C, of the valve, or the end of the port C, may be made conical, or tapered,
to receive the coned or recessed end of the union.
Fitted inside the body A, is a hollow plug K, which can be revolved, and may
be either circular, a segment of a circle in sectional plan, or of such other form as
circumstances may require, and which may be made either of cast, or of sheet,
metal, or any metallic or other suitable substances.
The plug K, is provided at its base with a stud, or stop L, which coming in
contact with the flange D, inside the body A, herein before described, acts as a
stop in each direction, left or right respectively, or in the body A, of the valve a
recess L, Fig. 4, may be made, of such a length as may be desired, and into which
the projecting portion S¹, Fig. 4, at the end of the spindle S, may be inserted, and
which recess L', acts as a stop in each direction, left or right respectively. A
portion of the body of the plug K, more or less considerable as may be desirable,
may be cut away in addition to the port, or branch M, so as to reduce the amount
of surface, and friction, and prevent the plug sticking
The plug K, is provided on one side or both sides with a port, or passage M,
corresponding with the port, or branch C, on the body of the valve; on one side is
made a vent N, of necessary size for the purposes when an apparatus, or arrange-
ment, or a portion thereof, is cut off by closing the valve, of maintaining equality
of pressure, and preventing a vacuum being formed on cooling down in that portion
of the apparatus or arrangement, and for supplying a sufficiency of steam, water,
or other fluid to maintain such a temperature in that portion of the apparatus, or
appliance, or portion thereof so cut off, as will prevent its being frozen.
The plug K, is sealed at its highest extremity with a disc or plate O, of larger
size, either loose, engaged, or attached thereto, and this disc or plate working, or
fitting, in, or on, the seating, or recess G, provided on the upper part of the
body A, as herein before described, forms a watertight joint. On the disc or
plate O, a projection P, hollow, or otherwise, may be provided with recesses, or
projections, or studs, to which the spindle S, may be engaged, by a cross bar,
or projecting stud, or studs, being provided on the end of the spindle S, which
cross bar, or stud, or studs, will correspond with, and fit into, a recess, or recesses,
in the projection P, formed on the top of the disc or plate O, by which the plug K,
may be revolved. In the upper edge of the plug K, Fig. 6 recesses Z, may be
formed, or projections arranged, to engage the lower end S¹ of the spindle S Fig. 4,

page_text: and turn the plug, or on the disc or plate O, a projection P, hollow, or otherwise,
may be provided with recesses or projections, and to which the spindle S, may be
engaged.
Between the disc or plate O, and the conical portion R, of the spindle or stock S,
herein before described, a spiral, or other, spring Q, may be placed to give such a
pressure as to keep the disc O, and also the conical portion R, of the spindle S, on
their respective seatings, thus rendering the valve self-packing, or on the spindle S,
a collar R, Fig. 2, may be made to receive a washer R2, of compressed fibre, or
other suitable material, and under the collar R¹, a spiral or other spring may be
placed to give such a pressure as to keep the various parts tight, as above.
described, or on the spindle S, a conical portion R, may be made with a screw, or
other guide R³, Fig. 3 thereto, which screw engages in a corresponding screw, or
guide, in the cap F, and the spindle provided with the screw on rotation forces
the conical portion R, of the spindle, or stock S, against the seat, and give such a
pressure as to keep this conical portion R, tight.
The spindle S, is passed through, the aperture H, in the cap F, and is more
or less conical, and is provided with a conical portion R, to correspond with the
conical portion of cap F, hereinbefore described. The hollow plug K, is moved by
means of the spindle, or stock S, which engages, or is connected with, either the
projection P, on the disc or plate O, or in the upper edge of the plug K, Fig. 6,
recesses Z, may be formed, or projections arranged, to engage the lower end of
the spindle S, Fig. 4, and turn the plug, or one or more brackets, or arms, or
projections, may be made in the interior of the plug K, Fig. 5, to engage the
lower end of the spindle S, and turn the plug K, and on the top of the spindle is
fixed a hand wheel T, or other suitable appliance, by which the valve can be
opened, or closed, at half a turn or less.
The aperture H, in cap F, where the spindle S, is passed through, is closed
externally with a hollow gland nut U, or in such other way as may be desirable.
The union V, is fitted with a union nut W, and the end of union may be
recessed, and an annular ring J, of compressed fibre, white-metal, or other
substance, fitted into it to act as packing, or the end of the union may be made
conical externally, as in Fig. 7, to correspond with, and fit into, the coned end
of the branch, or port C, of the valve, either of which when brought in contact
with the branch way of the valve by the connecting nut W, make a tight joint,
or the end of the union may be made conical, or tapered, to receive a compressed
fibre ring fitted on the port C, of the valve.
The inside of the tail, or connecting piece, of the union, has on its internal
face two flanges X, on opposite sides so that by inserting a bar, key, or other
arrangement, the union V, may be easily and satisfactorily screwed up without
risk of damage to the external surface of the connecting piece.
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 my
claim is ;-
1. The improvements in valves and unions, or valves and unions combined
substantially as and for the purpose or purposes hereinbefore described, and as
illustrated in the accompanying drawings.
