PROVISIONAL SPECIFICATION.
Improvements in or connected with Ball Taps or Valves.
I GEORGE OULTON, of the Firm of Dodd and Oulton, of Stanley Street
Liverpool in the County of Lancaster, Manufacturer, do hereby declare the nature
of this invention to be as follows:-
My invention relates to ball taps or valves for storage and water waste pre-
venting cisterns and the like, and consists in the improved manner of forming and
attaching the valve seat, the object of this invention being to produce the tap or
valve in a cheaper and more convenient manner, and to make the seating thereof
readily renewable and self-adjusting.
In ball taps of ordinary construction the valve seat is generally formed with the
casing, in one piece, being cored out in moulding and afterwards faced with special
tools. This does not permit of the valve seat being readily refaced, and when the
seat alone is done for, the whole valve must be renewed.
In some cases the valve seat has been made loose and separate from the casing
and has been afterwards screwed into the casing from the back of the same. Also
a separate valve seat has been inserted from the outlet end of the casing.
Now according to my invention, the valve seating is made in an independent
manner from the casing or body of the valve and fitted in such manner that it may
be readily removed and examined, and replaced or renewed, when required, and
when replaced will always find the true central position previously determined. It
may also when necessary be made of a different material to the body of the valve,
such as would resist the corroding action of impure water.
For the purpose of this invention the valve casing or body is specially bored out
at the inlet end; the boring being by preference conical. Into this specially
bored part is fitted an independent pipe, nozzle-piece or spigot which has a valve
seat formed at its outlet or inner end.
The nozzle-piece is formed in part as a liner so that it may be secured to the
body or casing of the valve by a screw cap, and connected to the supply pipe by
soldering, or prepared for connection in any other suitable manner.
The nozzle piece may be made in more than one part.

COMPLETE SPECIFICATION.
Improvements in or connected with Ball Taps or Valves.
I, GEORGE OULTON of the Firm of Dodd and Oulton of Stanley Street,
Liverpool in the County of Lancaster, Manufacturer 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 relates to ball-taps or valves for water-waste-preventing cisterns,
storage cisterns or tanks and for water and other liquid-supply pipes; the invention
is also applicable to steam-shut-off valves.

page_text: The object of this invention is to produce a cheaper and more durable article
and one which can be more readily repaired and in the case of valves operated by
floats more readily adjusted.
In ball-taps and valves of ordinary construction the valve-seat is generally
formed in the casing or chamber in one piece and faced in position. Valves made
according to this method are more costly than those made according to my
invention, and when the seats of such are worn out the whole valve has to be
replaced.
In some cases the valve-seat has been made loose and separate from the chamber
and has been afterwards screwed into the chamber from the back of the same.
Also in other cases a separate valve-seat has been inserted from the outlet-end of
the casing.
Neither of these methods is satisfactory in practice owing in one case to the
difficulty of obtaining a seat true with the spindle or its equivalent when formed
apart from the casing and afterwards screwed in, and in both cases to extra cost
and doubtful utility.
My invention consists in the improved manner of forming the valve and
attaching the valve-seat according to which manner the valve is made in two
main or essential parts, one part containing the valve-seating, and the other part
constituting the valve-chamber and carrying the valve-spindle or its equivalent.
In the case of valves which have the pressure of the fluid against the face of
the spindle so that they are closed against the pressure, that part of the valve
containing the seat is fixed in connection with the supply-pipe, vessel or other
source.
In other cases where the valve is closed by or with the pressure of the fluid
the chamber portion of the valve is fixed to the supply-pipe or vessel.
Generally however I fix the part of the valve containing the valve-seat to
the supply-pipe or vessel, so that the fluid first passes through this part of the
valve.
In order that the carrying out of my invention may be more readily understood
I have attached hereinto two sheets of drawings to which I will now refer.
In the said drawings the figures on Sheet 1 illustrate the construction of a
valve made according to my invention with reference to the forming and fitting of
the valve-seating and supply-pipe nozzle of the class used for storage and water-
waste preventing cisterns and opened and closed through the rise and fall of the
water therein which acts upon a float: the weight of the float and arm causing
the valve to remain open when the water-level is lowered, and the buoyancy of the
float upon the surface of the water when the water has risen causes the valve to
close. These figures shew one method of causing the valve to lift by means of a
float at the end of an arm. There are various methods of doing this such as the
use of a coarse screw-down valve, and toggle and compound-lever arrangements,
but the manner of opening the valve is not a part of my invention and I therefore
shew only one well known method.
The figures on Sheet 2 illustrate the construction of screw-down valves made
according to my invention with reference to the forming and fitting of the valve-
seating and shewing the manner of attaching or fixing such cocks, taps or valves
to tables, vessels and other fixtures, so that one part of the valve may be readily
removed for the purpose of examining or repairing the valve seating which is
thereby conveniently exposed. Upon this sheet the illustrations represents a
lavatory-valve or tap and the manner of attachment of the same to any suitable
fixture. The figures on Sheet 3 illustrated the application of my invention to what
is known as a "bib"-cock. I do not confine myself to these particular forms of
tap or cock in applying my invention. I may alter the form of any well known
pattern of tap, cock or valve for any purpose whatever so that I may form and fit
the seating according to my invention.
Referring now to the several figures on the two sheets,
Fig. 1 represents a valve opened and closed by the weight and buoyancy of a

page_text: lever and float which latter rises with the surface of the liquid in a cistern or
vessel, the valve being specially applicable to water-waste preventing and storage-..
cisterns.
Fig. 2 represents a part of the valve containing the valve-seating.
Figure 3 represents a similar valve but shewing the mammer of attachment to a.
vessel or fixture.
Fig. 4 shews a part of the valve containing the valve-seating.
Figure 5 represents a part-sectional view of a lavatory-valve shewing the manner
of formation and fitting of the seating and supply-nozzle.
Figure 6 represents a part of the valve which contains the seating detached.
In the several views like parts are indicated by similar letters of reference.
Figure 1 represents a valve of a well known pattern operated by a ball-float and
lever, in which however the construction is carried out according to my invention.
The valve is made in two parts A and B; the part A forming the valve-chamber and
carrying the valve or valve-spindle a. The valve is caused to open or close by the
movement of the lever or arm a¹ having a ball float a² made and arranged in the well-
known way. Instead of forming the valve-seating b in one piece with the chamber
or casing A as is usually done or screwing the seating directly into the chamber
or casing A, I form the casing A with an externally screwed faucet a³ and I bore
this faucet out conically as shewn in section at. Into this conic boring I fit the
second part of the valve B forming a spigot and having a passage therethrough,
and valve-seating and collar b¹. The spigot B as shewn is inade for attachment.
to a lead or composite pipe by solder, but it is obvious that it may be connected to
any pipe or vessel in any suitable way. The spigot B is secured in position to the
casing A by a screw-cap or union C. Figure 2 shews the spigot B and screw-cap C-
detached from the valve-chamber A.
Figure 3 shews a similar valve constructed in a similar manner but having the
externally screwed faucet a³ lengthened in order to securely attach the valve or
casing to a tank, cistern or other fixture by the nut D in the manner shewn ;.
representing in section the wall of the tank or other fixture. The spigot B
having the valve-seating formed thereon is lengthened in a corresponding degree.
Figure 5 illustrates the manner of constructing a screw down valve according to-
my invention.
The valve-casing or chamber A carrying the valve-spindle or
valve a forms one part; and the screwed spigot B containing the seating 6 forms a
second part. The spigot B is fitted and secured to the valve-chamber A in the
same manner as described with reference to Figures 1 and 3, and as illustrated in
part section in Figure 5. The part B of the valve may be secured to the fixture x-
in the manner shewn in Figure 5 by nuts D and D', the nut D being formed with.
a boss d which when screwed up against the collar 62 allows the screw cap C to
turn freely when connecting the valve-chamber or casing A. A liner E for the-
purpose of connecting a lead or composite pipe to the valve or tap may be secured
to the part B by a screw-cap or union F in the manner shewn. Figure 6 shews.
the part B of the valve or tap having the valve-seating 6 formed thereon, detached
from the valve-casing. Figure 7 illustrates what is known as a "bib "-cock con--
sisting of the two parts, A the valve chamber and B the valve seating made.
according to our invention. Figure 8 shews the part B containing the valve-seating.
and formed for attachment to a lead or composite pipe.
The advantages of this construction of valve or tap will be apparent from.
the above description and drawings attached. In the cases of the valves
illustrated in Figures 1, 5 and 7 the valve chamber or casing may be readily
removed in order to expose the valve-seating. In the case illustrated in Figure 3
the part B containing the seat b may be drawn away from the part A or
valve-casing, and in each case the valve-seating may be readily repaired upon the
spot.
Moreover, especially in the cases of valves operated by floats as hereinbefore.
described it is necessary that they should be set so true that the lever a' shall
move with perfect freedom otherwise there is a liability to stick at the joint ;.

page_text: by this construction the valve casing may be readily adjusted without fear of
breaking the joint of the pipe with the part B. Further the conic fitting of the
parts A and B together obviates the necessity of the use of packing.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
First. The improvements in and relating to valves and ball-taps substantially as
and for the purposes hereinbefore described and illustrated and in and by the
accompanying drawings.
Second. A valve or ball-tap in which the chamber or casing containing the
valve-spindle, disc or equivalent forms one part and in which a second part con-
taining the valve-seating is fitted to the first part by a conic joint and secured by a
screw-cap or union substantially as and for the purpose hereinbefore described and
illustrated, and in and by the accompanying drawings.
Third. A valve in which the seating is conically fitted or bushed into the
chamber or casing and secured by a screw-cap or union thereto substantially as and
for the purposes herein set forth.
