PROVISIONAL SPECIFICATION.
Improvements in or connected with Taps or Cocks.
I, ABRAHAM HALEWOOD, of Wallasey, in the County of Chester, Waste Water
Inspector, do hereby declare the nature of my said invention to be as follows:-
This invention has reference, mainly, to metallic taps-(including ball-taps)-or
cocks, used for controlling the flow or supply of water and other liquids or fluids, not
highly corrosive to brass, gunmetal, iron, and the like, in which the flow or supply is
controlled by a valve; and it has for its object to render this class of taps or cocks
more durable, and less liable to become leaky than those now commonly used, and at
the same time to so construct them that they shall be capable of being cheaply made,
and as easily examined and attended to, as those at present in common use.
To the above end, and according to this invention, taps or cocks of brass, gunmetal,
iron, or other like metal, are provided with a valve, adapted to be worked in the
ordinary or any known way, whilst the seat or bed on which the valve works is made
of glass, earthenware, porcelain, or other suitable durable and imperishable material,
and fitted into the metal body of the tap or cock.
By this means, leaking due to the wearing away of the seat or be: by friction or
otherwise which I have found in practice to be the chief cause of leaks incapable of
being stopped by the renovation of the valve face-is rendered impossible.
The kind of valved tap or cock which I prefer to use in combination with the body
having the glass, porcelain or other seat above specified, is that in which the face of
the valve is detachable, and of a yielding nature, such as leather, indiarubber,
vulcanized fibre," "woodite," and the like, and the valve is capable of being pressed
onto and raised off its seat in the ordinary or any known suitable way. In such a
combination, the valve seat is detachable and renewable and in the form of a chamber,
and is fitted into a suitable recess in the body of the tap. The seat is provided with
one or more suitable shoulders or flanges, to make a tight joint within the metal of
the tap, washers being preferably interposed between the shoulders of the seat and the
corresponding joint face of the tap, and the whole seat being kept in position by a
screw, or otherwise suitably attached, cap or plug.
The fluid in passing through the tap, enters the seat chamber below the valve, by a
suitable aperture therein, which coincides when in position, with a corresponding
aperture in the metal of the tap body, and then flows on between the seat surface and
the valve, in the usual way.
Although in the above Specification I have set forth the application of this invention
more particularly with reference to a certain kind or class of taps or cocks, I wish it
to be understood that it may, by simple modifications, be applied to other kinds, and
in ways differing in form, arrangement, and disposition of parts to that which I have
specified; I also wish it to be understood that the detachable seat when arranged and
constructed as herein set forth may be made of suitable hard metal instead of glass,
earthenware or other like material, as specified.
Dated this 24th day of April 1890.

I, ABRAHAM HALEWOOD, of Wallasey, in the County of Chester, Waste Water
Inspector, 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, mainly, to metallic taps (including ball taps), cocks or
valves used for controlling the flow or supply of water and other liquids or fluids, not
highly corrosive to brass, gunmetal, iron, pewter and the like, in which the flow or
supply is controlled by a valve; and it has mainly for its object to render this class
of taps, cocks or valves more durable, and less liable to become leaky than those now
commonly used, and at the same time to so construct them that they shall be capable
of being cheaply made, and as easily examined and attended to, as those at present in
common use. It has also for its object to convert at slight cost existing imperfect
and disused taps into perfect and durable taps.
To the above end and according to this invention, taps, cocks or valves of brass, gun-
metal, iron or other like metal, are provided with a valve, adapted to be worked in
the ordinary or any known way, whilst the seat or bed on which the valve works is
made of glass, earthenware, pottery-ware, porcelain, or other suitable equivalent
durable and imperishable material, and fitted into the metal body of the tap or cock.
By this means leaking, due to the wearing away of the seat or bed by friction or
otherwise which I have found in practice to be the chief cause of leaks incapable
of being stopped by the renovation of the valve face-is rendered practically
impossible.
The kind of valved tap or cock which I prefer to use in combination with the body
having the glass, porcelain or other like seat above specified, is that in which the face of
the valve is detachable, and of a yielding nature, such as leather, indiarubber,
"vulcanized fibre," "woodite" and the like, and the valve is capable of being pressed
on to and raised off its seat in the ordinary or any known suitable way; nevertheless
if the seat bearing surface be tooled and ground or incased, the valve face may be
metallic, or of a non-yielding nature. The valve seat is detachable and renewable and
in the form of a chamber or ring, and is fitted into a suitable recess in the body of the
tap. The seat is provided with one or more suitable shoulders or flanges, to make
the necessary tight joint within the body of the tap, washers being interposed between
the shoulders of the seat and the corresponding joint face of the tap, and the whole
seat being kept in position by a screw, or otherwise suitably attached cap or plug, or
by a bayonet joint or the like.
The fluid in passing through the tap, cock or valve, enters the seat, when in the
form of a chamber, below the valve, by a suitable aperture therein, which coincides
when in position, with a corresponding aperture in the metal of the body, and then
flows on between the seat surface and the valve, in the usual way.
•
In the drawings which serve to illustrate my invention, I shew by way of examples
two kinds of taps or valves, provided with seats according thereto.
Figure 1 is a sectional elevation of a tap of an ordinary screw-down type.
Figure 2 is an outside elevation of the tap seat above specified, and Figure 3 is a
plan of same.
Figure 4 is a sectional elevation of a ball tap, according to the invention, and
Figure 5 is an outside view of the seat.
Figures 6, 7 and 8 shew modifications of my invention.
The same letters and figures of reference are used to denote the same or equivalent
parts wherever they occur in the drawings.
With reference to the drawings, a is the separate or detachable seat of the tap : bis
the valve in Figure 1-is the valve spindle, or-in Figure 4-the ball or float

lever is the inlet conduit or passage of the valve, and e is the outlet conduit or
passage, and is the body of the tap.
The valves bare of an ordinary well-known kind, and are preferably provided with
a face of a yielding nature, such as leather, indiarubber, "vulcanized fibre," "woodite "
or the like, which face in the case shewn in Figure 1 lies within an inverted metallic
cap and so arranged that the lower edge of such cap will come into contact with the
metal ring before the washer wears through. In the tap shewn in Figure 1 the
valve is raised on and off the seat a by the valve spindle c, which is screwed at c¹ and
works in a corresponding thread in the body of the tap in the usual way, whilst in the
ball-tap in Figure 4 the valve is moved on and off its seat by the lever c. Both these
kinds of taps, and their manner of working are well-known, and therefore need no
further description.
The seat a, illustrated in Figures 1, 2 and 3, is in the form of a hollow chamber
having an inlet aperture through which the liquid flows from the passage d to the
interior of the chamber; such aperture, of course, when placed in the body of the
tap, coincides with the said inlet passage d. At its upper portion, the seat chamber a
is reduced in diameter as shewn, whereby there is provided an annular shoulder, and
between this shoulder and the annular, inwardly projecting ring k of the body, the
packing washer m is provided. This washer, together with the said shoulder and
ring k, makes a liquid tight joint between the inlet aperture and the outlet of the seat,
and so prevents leakage of liquid into the upper part of the body of the tap between
the interior surface of the body and the seat."
The seat is held in position by the lower screw plug n, and this plug also serves to
press the seat on the washer m and render the joint between it and the ring k good.
Or if the seat be held in position by a bayonet joint as above referred to, or in any
other equivalent suitable way, the cap or plug n serves merely to close the bottom of
the body f
It is to be understood the seat a is not necessarily of the form shewn, as already
stated, as it may be in the form of a simple shouldered or tapered plug or ring, after
the form of that shewn in Figures 4 and 5, or modifications thereof, or of any analogous
or equivalent shape or construction.
Referring now to Figures 4 and 5, the seat a is a plain open way one, having an
enlarged part at a¹ forming a double shoulder, the front one of which bears against the
washer m, and makes the necessary liquid tight joint already specified, whilst the rear
one provides a projection against which the screwed thimble n presses and keeps the
seat in place and up against the washer m. A washer o may also be interposed between
the thimble and the portion a¹.
The seat shewn in these Figures 4 and 5 represents the form in which it is
made when wholly of blown glass. This form and kind may be adapted in valves
of the kind shewn in Figure 1 and others, if desired; or a modification of it, as
shewn in Figure 6, may be used with advantage. These latter forms may also be
made of other materials than blown glass, such as of cast glass, or of any of the
substances specified or referred to herein.
In the modifications of my invention shewn in Figures 7 and 8, I show two forms of
reversible seats, the main constructions or formations of which are those of the seats,
shewn in Figures 1 to 3, and 4 and 5. By this construction the seats may be applied
with either end adapted to receive the valve and to serve as the bearing edge therefor,
and if one is, or becomes defective, from any cause, by reversing it in the body of the
tap or valve, the other can be used. In the example herein given the bearing edge of
the seat stands above or beyond the metal of the body in which it is placed.
Although in the above Specification I have set forth the application of this invention
more particularly with reference to two certain kinds or classes of taps or cocks, 1 wish
it to be understood that it may be applied to other kinds, and in ways differing in
forms to that which I have particularly specified and it may also be applied to most
forms of stop valves, and other lift valves, or valves operating after the manner of such
valves.
