GUMI LELE SIPITIVATION
An Improved Tap.
I, WILLIAM SINCLAIR MACKAY of Everton, in the Colony of Victoria,
Grazier, do hereby declare the nature of this invention and in what manner the
Bame is to be performed, to be particularly described and ascertained in and by
the following statement :-
This invention has been devised to provide a simple, efficient and cheaply
constructed tap for water pipes and the like and obviates the cost of construction
and maintenance of the usual screw-threaded spindles and packing boxes or glands,
moreover my improved tap permits the water or other liquid to pour from the
tap box in a practically unobstructed stream.
In describing my invention in detail I will now refer to the accompanying
drawings in which-
Figure 1 is a view of my tap shewn partially in section.
Figure 2 shews an alternate arrangement also partially in section.
I provide two somewhat bell-mouthed or flared tubes "A," "B" one of which
is inverted. These have preferably threaded portions "C" arranged to be screwed
one into the other, the portion "A" has a threaded neck "A" arranged to be
screwed into the water pipe. In the interior of the tube "B" at the junction of
the flared portion of same and neck "B1" is arranged a valve seating "B." This
seating may consist of either a simple turned face tapered to suit the corresponding
angle of a plug or taper valve or be constructed of a ring either added to or
forming part of the tube in which it is set.
I employ a tapered. or plug-shaped valve "D" (Fig. 1) of metal or other
suitable material shaped so as to fit upon the seat "B" aforesaid the said valve
preferably has a leather washer "D1" which rests upon the seating "B"-to this
valve is secured a rod "E." A lever "F" is centred at "F" in the bifurcated
end of an arm "G" which depends from the bell-mouthed or flared portion "B,"
the lever is linked by a pin "E" in the bifurcated end of rod "E." The arra "G"
has one or more niches as "G" cut in it and in which a pawl "H" (centred
at "H"
upon the lever "F") is arranged to engage.
The tap is operated by pressing down the free end of the lever "F" which thus
raises the valve "D" from its seat and allows the water or other liquid to flow out
through the neck "B." The lever "F" thus lowered at its free end will cause
the pawl "H" to fall into the niche "G" and so form a stop so that the water
will be free to flow until the said pawl "H" is withdrawn from the said niche "G"
and the pressure released from the lever "F." The water pressure within the tap
will force and maintain the valve "D" hard upon its seat "B" and thus prevent
any undesired flow of liquid until the lever "F" is again depressed.
In the alternate form shewn on Fig. 2 it will be seen that the valve, in this case,
is in the form of a ball "J" in lieu of the plug "D" aforesaid, and is arranged to
rest upon a suitable seat "B2" as before, the ball being connected with a rod "K"
which is linked to a rod "K" which latter terminates in a handle ring "K"
arranged to be hung upon a hook "L" secured to the tap. This form of appliance
is operated, when a flow of water is required, by raising the ball from its seat by
means of the linked rods "K, K." The valve may be retained above its seat
when desired by hanging the link "K" upon the book "L" when the water will
be free to flow until said handle "K" be released. The water pressure within the
tap will on releasing the rod "K" close the ball upon its seating so as to prevent
any further flow of the liquid until it be again operated in manner described.

page_text: I desire it to be understood that I do not arbitrarily confine myself to a rigid
adherence to the forms of valves shewn on Figs. 1 and 2 but may employ any
other suitable valve in lieu thereof.
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 1
claim is--
1. In a tap-
Bell-mouthed or flared tubes as "A, B" secured to one another and having a
seating arranged at the junction of a bell-mouthed or flared portion with a neck
of a tube in combination with a valve substantially as and for the purposes set
forth.
2. A tap consisting of bell-mouthed or flared tubes as "A" and "B" in
combination with valve as "D" and rod as "E" actuated by lever as "F"
substantially as and for the purposes set forth.
3. In a tap
The combination with bell-mouthed or flared tubes as "A, B" and a lever
as "F" of a pawl as "H" and niche as "G" substantially as and for the
purposes set forth.
4. A tap having portions "A" and "B" in combination with a valve as "J"
links as "K, KI" and hook as "L" substantially as and for the purposes set
forth.
5. The general combination and arrangement of all the parts substantially as
described and as illustrated on Fig. 1 of the accompanying drawing.
