PROVISIONAL SPECIFICATION.
Improvements in and applicable to Taps, Valves, or Cocks for Steam
and other Fluids, Water, and other Liquids.
I, JOHN OBADIAH BROOKE, of Wakefield, in the County of York, Plumber
and Sanitary Engineer, do hereby declare the nature of this invention to be as
follows:-
My invention has reference to certain improvements in and applicable to taps,
valves, or cocks used for steam and other fluids, water and other liquids, of the
kind known as screw taps, valves, or cocks, in which the action of the screw opens
or closes the valve, and in which, hitherto, screwed spindles have mostly been
employed for the said purpose of opening and closing the valve.
According to my said improvements I employ a plain or unscrewed spindle
having the valve upon or connected to its lower end, and at its top end connected
with a threaded cap or cover (with or without wings or handles) which screws on
to the upper part or neck of the body of the tap, and by means of which the
spindle operating the valve can be raised or lowered, so as to move the valve off
its seating or on to it, as required for the opening or closing of the tap.
The valve may be made as one with the spindle, or separate therefrom, and the
valve or seat of the tap may be formed of any suitable alloy, composition or sub-
stance to better withstand wear and tear, or the action of corrosive water and the
like, than the ordinary metal.
The said spindle may be connected with the cap or cover aforesaid, so as to
revolve with the same, or connected so that while the cap revolves, the spindle
does not revolve.
Further, my said improvements are applicable to all kinds of screw-down taps
or cocks, having stuffing boxes, flexible diaphragms, or any other arrangement for
preventing the escape of water, or other liquid or fluid, past the spindle and out of
the top of the tap.

COMPLETE SPECIFICATION.
Improvements in and applicable to Taps, Valves, or Cooks for Steam
and other Fluids, Water, and other Liquids.
I, JOHN OBADIAH BROOKE, of Wakefield, in the County of York, Plumber
and Sanitary 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 :-
My invention has reference to certain improvements in and applicable to taps,
valves, or cocks, used for steam and other fluids, water and other liquids, of the
kind known as screw taps, valves, or cocks, in which the action of the screw opens
or closes the valve, and in which hitherto screwed spindles have mostly been
employed for the said purpose of opening and closing the valve.

page_text: Figs. 3, and 4, show modifications of valves and washers for such taps, cocks, or
valves.
Figs. 5, and 6, are sectional side elevations showing part of my said improve-
ments applied to the construction of taps in which the opening between the "inlet"
and "outlet" connections is closed by means of a ball.
Figs. 7 and 8, are further sectional side elevations of taps, cocks, or valves in
accordance with my improvements.
According to my said improvements I employ a plain or unscrewed spindle A,
having the valve upon or connected to its lower end, and its top end connected with
a threaded cap or cover C (with or without wings or handles D) which screws on
to the upper part or neck E of the body of the tap, and by means of which the
spindle A, operating the valve, can be raised or lowered, so as to move the valve
off its seating F, or on to it, as required for the opening or closing of the tap.
The valve may be made as one with the spindle, or separate therefrom, and
either the valve or seat of the tap or both may be formed of any suitable alloy,
composition or substance, to better withstand wear and tear, or the action of
corrosive water and the like, than the ordinary metal.
The said spindle A is connected with the cap or cover C so as to revolve with
the same, or connected so that while the cap or cover C revolves the spindle A
does not revolve. In the arrangement shown in Fig. 1, the spindle A is square,
and has a round collar G, a round portion H, a square portion I, and a screwed
portion J at its upper end, and a screwed portion K at its lower end. The round
portion H of the spindle A passes or fits into a corresponding hole in the threaded
cap or cover C, the square portion I having a metal washer L (with square hole)
to fit thereon, and the threaded portion Jhaving a screwed nut M which, while
allowing the screwed cap or cover C to revolve around the round portion H of the
spindle A, prevents it from coming off the same by means of the washer L. The
valve arrangement in this figure consists of a metal bush N, screwing on to the
spindle A, by means of the threaded portion K, O is a cup shaped valve with
screw P for fixing into bush N, (the bush N and valve O may be made in one
piece, if preferred). The valve seating F is made of washer ¹ held in position
by screwed ring F³, (such as patented by ine under Patent 16020 of 1890). Fitted
on the spindle A, between the bush N and the upper part or neck E of the body
of the tap, is a packing ring R made of rubber or other elastic material. The
action of this arrangement is as follows:-As the cap or cover C is screwed down
upon the threaded upper part or neck E of the body of the tap, it revolves around
the round portion H of the spindle A, presses on the collar G, and thereby
depresses the valve O onto the seating F, the spindle A and valve O having no
tendency to revolve.
When the action is reversed the cap or cover C presses against the washer L
fixed by the nut M, and thereby lifts the valve O from off its seating and opens
the
passage. Also, as the valve is opened the rubber ring or packing R is com-
pressed between the parts previously referred to, so preventing the escape of water
past the spindle A, and doing away with the need of a stuffing-box.
In the arrangement shown in Fig. 2, the spindle A is round and has a collar G
and a square portion H which fits into a corresponding hole in the threaded cap or
cover G, the said square portion H also receiving a washer L and screw J by
which the parts are secured together. The neck or upper part E of the body of
the tap, in this modification is combined with a bush E having the necessary
water ways and resting upon the washer F' of the seating F. In this modification
a stuffing box R is used.
The action of this modification is as follows:-As the cap or cover C is screwed
down upon the threaded upper part or neck E of the body of the tap the spindle A
and valve O turn with it, so that the valve O is depressed onto the seating F, and
the passage closed.
In Figs. 5 and 6 part of my said improvements are shown applied to the con-
struction of taps (such as patented by me under Patent No. 16019%) in which thẹ

page_text: opening between the "inlet" and "outlet" connections is closed by means of a
loose ball. According to these arrangements A is a square and plain or unscrewed
spindle screwing at its lower end into the enlarged end of a rod A' which is cup-
shaped at its lower end. The top end of the said spindle A has a collar G and a
round portion H fitting into a corresponding hole in the screwed cap or cover C, the
end of the spindle A has a square portion I, receiving a nut M, and pin or screw.
In Fig. 5 the bush E' referred to in Fig. 2 is screwed into the tap, and holds the
loose unthreaded ring F (which forms the seating for the loose ball B) in position
and against the pressure exerted by the ball when forced upward by the action of
the water.
The action of these modifications is as follows:-On screwing down the threaded
cap or cover C as before explained, the rod A' forces the loose ball B away from
its seating, and holds it there until on screwing up the threaded cap or cover C the
rod A' is taken away from the ball B, which resumes its normal position against
the seating.
In Figures 6 and 7 the loose unthreaded ring F forming the valve seating is
made in the form of a tube (having water-ways) and secured in position by screw
cap F³.
In the arrangement shown in Fig. 7, A is a square and plain or unscrewed
spindle, having à collar G and round portion H fitting into a corresponding hole
in the screwed cap or cover C, a square portion I, and nut M, secured by più or
screw.
The lower end of the spindle screws into the bush N to which the flat valve O
having a washer O' is secured; the valve seating being constructed as described
with reference to Fig. 6.
In the arrangement shown in Fig. 8, A is a round and plain or unthreaded
spindle, having a collar G and square portion H fitting into a corresponding hole
in the screwed cap or cover C, and secured at its top end by nut M and pin or
screw. The valve O, which has a washer O¹, is secured or cast to the spindle A.;
the valve seating being of the ordinary or well known kind.
The actions of these two modifications will be readily understood from the fore-
going descriptions.
It will be readily seen that my said improvements are applicable to such kinds
of screw down taps valves or cocks as have stuffing-boxes, flexible diaphragms or
such other arrangement for preventing the escape of water or other liquid or fluid
past the spindle and out of the top of the tap, valve, or cock, and how my said
improvements may be applied to such further taps valves or cocks as the drawings
do not particularly illustrate.
Figs. 3, and 4. The bush N has a washer N¹ secured by screwed ring N³, Fig. 3
being suitable for flat seatings, and Fig. 4 for raised or ridged seatings.
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 what I
claim is :-
1. In a screw down tap, cock, or valve for steam and other fluids, water and
other liquids, the combination of a plain or unthreaded spindle A, and a screwed
cap or cover C, working on the upper part or neck E of the body of the tap, cock,
or valve, as and for the purposes shown and described.
2. In a screw down tap, cock, or valve for steam and other fluids, water and
other, liquids, the combination of a square and plain or unthreaded spindle A
having a collar G, round portion H, square portion 1, washer L, threaded portion J,
nut M, cap or cover C, upper part or neck E, packing R, valve O, and valve
seating F, as and for the purposes shown and described.
3. In a screw down tap, cock, or valve for steam and other fluids, water and
other liquids, the combination of a round and plain or unthreaded spindle A
having a collar G, square portion H, washer L, screw J, cap or cover C, upper

page_text: part or neck E, valve O, and valve seating F, as and for the purposes shown and
described.
4. In a screw down tap, cock, or valve for steam and other fluids, water and
other liquids, the construction of valve seating (which consists of a loose Lube F
having water-ways and secured or held in position by a screwed cap F³) such as
shown and described with reference to Figs. 6 and 7 of the drawings annexed.
5. In a screw down tap, cock, or valve for steam and other Huids, water and
other liquids, having a plain or unthreaded spindle A working in conjunction with
a screw cap or cover C upon the upper part or neck of the tap, cock or valve, of
the construction of valve seating (which consists of a loose tube F' having water-
ways and secured or held in position by a screwed cap F³), such as shown and
described with reference to Figs. 6 and 7 of the drawings annexed.
