PROVISIONAL SPECIFICATION.
Improvements in or relating to Taps for all kinds of Liquids,
whereby a Combination Check Valve and Tap is obtained, also
applicable for analogous purposes.
I, SAMUEL MASON of Dale End Birmingham in the County of Warwick
Barfitter do hereby declare the nature of this invention to be as follows:-
:-
This invention consists of forming a seating in the interior chamber of the tap at
the head of the outlet or supply channel thereof, of a cup like or any suitable
shape in order that it may receive a floating ball valve, which ball valve may
consist of india rubber or any other suitable material.
By the action of any back flow or back pressure of the liquid the ball valve
is caused to be forced firmly into the seating and thus closes the outlet or
channel.
When the liquid is drawn through the tap in the ordinary way it will force away
and flow past the ball valve and displacing it from the seating, cause the ball valve
to float in the chamber.
A cross bar or bars will intersect the tap or other suitable means will be adopted
to prevent the ball valve from leaving the chamber.
Dated this 27th day of November A.D. 1890.

COMPLETE SPECIFICATION.
Improvements in or relating to Taps for all kinds of Liquids,
whereby a Combination Check Valve and Tap is obtained, also
applicable for analogous purposes.
I, SAMUEL MASON of Dale End Birmingham in the County of Warwick
Barfitter, 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, reference being had to the drawings hereunto annexed
and to the figures and letters shewn thereon :—
Figure 1, is a sectional elevation of a tap.
Figure 2, is a section of a portion of a tap.
Figure 3, is a front elevation exposing the inner chamber and valve.
Figure 4, is a view of the valve detached.
This invention relates to taps for all kinds of liquids and consists in forming
a seating in the interior chamber of the tap to receive a ball valve within such
chamber.
Similar letters of reference relate to similar parts on all the figures.
A Figures 1, 2, and 3 is a tap having an interior chamber B at the head of the
outlet or supply channel thereof, C, this interior chamber B is made of a cup like
or any other suitable form in order that it may receive a floating ball valve D this
ball valve may consist preferably of india rubber as shewn but may be of any
suitable material other than india rubber,

page_text: The action of the floating ball valve or check valve is thus,
When any back flow, or back pressure of the liquid takes place the floating ball
valve or check valve D is caused to be forced firmly into the jaws or seating E of
the chamber B and thus the passage from the tap is closed to the outlet, seen in
Figure 1 on the other hand when the liquid is required to be drawn through the
tap in the ordinary way the pressure of the liquid in its passage through the tap
will obviously force away the ball valve or check valve D as seen in Figure 2, and
thus allow the liquid to flow past the ball valve and displacing it from its seating E
the ball valve D will float freely in the chamber B.
A cross bar F or bars will intersect the tap or other suitable means will be
provided to prevent the ball valve D from leaving the chamber B.
The evident advantage and object of this invention is to provide a combination
check valve and tap whereby it is impossible for any back flow or back wash of the
liquid to re-enter the barrel, and also a simple and effective method is obtained for
the beforenamed purpose.
I wish it to be understood that I do not confine myself to the herein described
specific details for carrying out my invention as I may when occasion may demand
vary the same to suit different requirements without materially departing from the
principle of this my invention.
Having now particularly described and ascertained the object and nature of
my invention and in what manner the same is to be performed, I declare that
what I claim is
The special manner of introducing a floating ball valve composed of any suitable
material into the interior of the tap and the manner in which the said ball valve
acts by the backward or forward pressure of the liquid substantially as herein set
forth and specified.
