PROVISIONAL SPECIFICATION.
Improvements in Combined Non-return Valves and Cocks.
THOMAS WILLIAM MOON 28 and 29 Gloster Road Brighton Licensed Victualler
do hereby declare the nature of this invention to be as follows:-
This invention has for its object the better arrangement of combined non-return
valves & cocks & is more especially adapted to cocks in use for beer & other
similar barrels where they are connected with a beer engine, the object of its use
being to prevent any return of beer or other fluid to the cask when once drawn out
as such return causes had results. Also to effect simplicity & ease in washing
cleaning & repairing.
Having now described the nature of my invention I will proceed to show one way
of carrying the same into effect. I arrange a tap with a taper plug ground in &
secured with a screw end & nut & washer in the usual way but I so construct the
tap & the plug that there are separate openings for the inlet & outlet that of the
inlet being arranged to pass into the lower part of the plug on one side & that of
the outlet on the opposite side of the plug at the upper end, the holes in the plug
& tap being arranged to coincide when the plug is turned in open position & to be
blanked when turned in closed position. Within the plug at a suitable position
between the inlet & outlet I place a valve of ball or other suitable form closing on
a seating of rubber or other material so that all that passes through the tap must
pass through this valve suitable provision being made for constructing the plug to
allow of the valve being placed therein. It will now be seen that when the plug of
the tap is so turned that the several openings therein coincide anything can run or be
drawn through the tap in one direction only & nothing can return.
If the plug is
so turned that the openings are not coincident it will be closed as with an ordinary
plug tap. The same principle may be applied to various kinds of cocks & valves &
also to syphon pipes.

Improvements in Combined Non-return Valves and Cocks.
I THOMAS WILLIAM MOON of Number 28 Gloster Road Brighton in the
County of Sussex Licensed Victualler 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 for its object the better arrangement of combined non-return
valves & cocks & is more especially adapted to cocks in use for beer & other
similar barrels where they are connected with a beer engine the object of its use
being to prevent any return of beer or other fluid to the cask when once drawn
out as such return causes bad results. Also to effect simplicity in cleaning &
repairing.
Having now described the nature of my invention I will proceed to shew one
way of carrying the same into effect. I arrange a tap with a taper plug fitted in

page_text: the usual way but I. so construct the tap & the plug that there are soparate openings
for the inlet & outlet, that of the inlet being arranged on the under part of the
plug on one side & that of the outlet on the opposite side of the plug at the
upper end.
The holes in the tap & plug being arranged to correspond when the plug is
turned in open position & to be blanked when turned in closed position: Within
the plug at a suitable position between the inlet & outlet I place a valve of suitable
form so that all that passes through the tap must pass through this valve suitable
provision being made in the plug to allow of the valve being placed therein. I will
now proceed to describe the drawing hereunto annexed.
Fig. 1. represents a tap in section constructed according to my invention & shewn
when the plug is turned to open.
A is the spigot constructed with holes in the usual manner & suitable to drive
into a cask or other vessel. B is the outlet capable of being coupled to the suction
pipe of a pump or beer engine. C is the plug capable of rotating in the body of
the tap & having a non-return valve D arranged inside & also with a removeable
cover E suitably secured to the plug & which forms the handle for turning the
same and also allows of fitting the valve D. and G are the openings in the plug
for inlet and outlet respectively and corresponding holes are arranged in the body
of the tap communicating with A & B. When the plug is turned half round
these openings are blanked and the tap is closed. When however the holes A & B
are coincident with the holes in the body of the tap any liquid which may be in the
cask into which the tap is fixed will tend to lift the valve D & so pass out more
especially if assisted by the pull of a pump or engine any liquid however which
remains in the suction pipe of the pump is retained by the non-return valve D and
cannot re-enter the cask, thus keeping the pipe always fully charged even if the
beer-engine or pump is faulty.
Having now particularly described & 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 combination of a tap having a hollow plug and a non return valve fitted in
same and openings in tap & plug so arranged that when turned in one position the
tap is closed and when turned in another position it acts as a non return valve
substantially as herein described.
