IMPROVEMENTS IN TAPS AND COCKS
Year: 1885

page_text: I WILLIAM FOSTER of Lawden Road Small Heath in the County of Warwick
Cock Founder do hereby declare the nature of my said invention for IMPROVEMENTS
IN TAPS AND COCKS to be as follows:-
This invention refers to improvements in the construction of taps and cocks so
that the tap or cock can be removed from the boss or union for the purpose of
repair without waste and in the case of liquor barrels for the purpose of securing
the contents or closing the barrel if empty.
With this view I employ a boss or union which is provided with a ball or other
suitable valve so placed that when the tap is screwed into it a plug which I form
upon the screwed end of the tap presses upon the valve in the boss forcing back the
valve and allowing free water way and when the tap is removed the action of the
plug being also removed the pressure of fluid at the back of the valve keeps it up
to its seating and prevents the fluid from flowing.

I WILLIAM FOSTER of Lawden Road Small Heath in the County of Warwick
Cock Founder do hereby declare the nature of my said invention.for IMPROVEMENTS
IN TAPS AND Cocks and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
This invention refers to improvements in the construction of Taps and Cocks so
that the tap or cock can be removed from the boss or union for the purpose of
repair without waste and in the case of liquor barrels for the purpose of securing
the contents or closing the barrel if empty.
With this view I employ a boss or union which is provided with a ball or other
suitable valve so placed that when the tap is screwed into it a plug which I form
upon the screwed end or neck of the tap presses upon the valve in the boss foring
back the valve and allowing free water way and when the tap is removed the
action of the plug being also removed the pressure of fluid at the back, of the valve
keeps it up to its seating and prevents the fluid from flowing.
This is applicable to taps and cocks for steam water and other fluids or gasses.
Referring to the drawings Fig. 1 is a view of a tap and boss (a) being the boss
or union (b) the neck of the tap which is screwed into the boss (a) Fig. 2. is a
section through the boss and neck of the tap when the tap is removed and Fig. 3 is
a section shewing the neck of the tap screwed into the boss.
(c) is a ball contained in the chamber (d) is a plug pin or projection so placed
upon the screwed end or neck portion (b) of the tap that when the tap is screwed
into the boss (a) the ball (c) is forced back by the pin (e) and thus allows of the
flow of the water or gas past it which was previously prevented by the pressure of
water or gas, behind the the ball forcing it against the ring or seating (f). Fig. 4
is a section shewing another construction of valve when open consisting of a disc
of either metal combined with leather or material or of metal alone which latter
would be used where a steam valve was required and Fig. 5 is a section of the same
valve when closed (9) is the valve and (h) a guide rod attached to it.
By this arrangement when the tap is screwed into position the disc is pushed
back from its seating (2) as shewn in Fig. 4 and when the tap is removed the
pressure from behind keeps it up to its seating as shewn in Fig. 5.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that
what I claim is
The improvements in taps and cocks substantially as herein set forth and
specified whereby the taps and cocks can be removed from the or union without
causing the of steam water or other fluids or gases from the pipe or recepticle to
which the tap or cock is applied.
