Improvements in Cocks or Valves.
I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co., Patent Agents,
45 Southampton Buildings, in the County of Middlesex, do hereby declare the nature
of this invention for "IMPROVEMENTS IN COCKS OR VALVES" and in what manner
the same is to be performed, to be particularly described and ascertained in and by the
following statement :—
This invention relates to improvements in the construction of taps, valves, bib cocks,
and the like used for tapping casks or other vessels for the purpose of extracting the
fluid contained therein.
The improvements consist in certain alterations to the ordinary casing or driving
faucet by providing a series of attachments consisting of a self-acting air vent
rendered operative during the working of a double acting valve placed within a
removable chamber in the faucet, such valve serving a twofold purpose namely as a
draw off or outlet tap or cock, and as a foot or retention valve for a beer engine or
pump. The air vent consists of a pipe, tube, or passage formed in a convenient part
of the faucet, having on its outer end a small chamber containing a single cup shaped
valve seating, for a ball valve, which, when not seated, rests upon a perforated guard
plate, so shaped as to prevent the valve closing the aperture of the tube or passage,
and thus allowing the air to pass into the interior of the faucet and thence to the
vossel.
The pressure of the liquid within the vessel will cause the vent valve to seat itself
and prevent an outflow, but when the double acting valve previously referred to is
set in motion for the purpose of drawing off the liquid, the vent valve will rest upon
the guard plate, thus allowing an inflow of air, which continues only during the time
the double acting valve is working.
The vent valve may be dispensed with where the faucet is used for the outflow of
liquid under pressure.
The attachment placed within the faucet serving the twofold purpose, before referred
to, consists of a valve chamber provided with two suitable cup shaped seatings (made
preferably of india-rubber) such seatings being held in position with screwed locking
rings or equivalent device. To the inner locking ring is attached a strainer which it
may be desirable to convert into a filtering chamber, in which case the filtering
material may be placed within the strainer although if desired a concentric ring of
compressed filtering material may be interposed between the strainer and the outer
casing of the faucet. The valve chamber is secured within the faucet by means of a
screw upon its inner end. If desired this screw may be dispensed with and the
chamber made taper and driven into position, the screw being used preferably for
convenience of withdrawal of the valve chamber with strainer attached for cleansing
purposes. Slits are provided in the end of valve chamber and outer locking ring to
facilitate the work of removal. A ball valve is used where cup headed seatings are
employed, but where it may be considered advisable to use seatings with flat surfaces
a correspondingly suitable valve would be substituted. The valve may be made of
any suitable substance such as metal, glass, wood, gutta percha, or vulcanite.
No springs are necessary for the retention of the valve, as the outflow of the
liquid gives the necessary pressure to hold it against the seating. The faucet or
casing is made taper and provided at the small or inner end with perforations leading
to a straining chamber and filter. The large or outer end of the faucet is provided
with an external screw upon which are fitted three classes of improved attachmenti

page_text: cach to be used in conjunction with the inner valve chamber, they may be fitted
thereon in the order in which they are required to be used. One attachment is a
driving cap which protects the thread of the external screw from injury when it is
desired to drive the faucet into the cask or vessel. Another is a similar cap pierced
centrally to receive a union or lining which is the form of connection used when it
is desired to connect with a beer engine or pump. Other kinds of unions may
be used.
The inner end of the union or lining is provided with a collar having a packing
ring. The body of the collar fits the largest part of the bore of the faucet and
the packing ring is placed upon the collar. Projecting beyond the collar and
fitted within the union or lining is a triangular shaped projecting piece, whose
office is to thrust the valve inward away from the outer seating which is done by
simply screwing the cap upon the end provided for it. As it is being screwed
in me a projecting piece enters the locking ring and gradually pressing inwards
displaces the valve and ultimately brings the packing ring close against the face
of the faucet end, thus making an air tight joint. It is obvious that, the triangular
projecting piece will not impede the outflow of the liquid.
While liquid is flowing out the valve will take its seating upon the cup end of
the projecting piece, but when the beer engine or pump is being operated it will
move alternately with the outward and backward pressures. By reason of the
backward pressure it will take its seat upon the inner valve seating and will retain
the liquid in the connecting pipe attached to the pump, and prevent its return to
the cask or vessel. The pipe is therefore fully charged whenever it is desirable to
operate the beer engine or pump.
Another attachment consists of a screw cap and union made in the form of a bib
cock. In this attachment the cap may be screwed quite home and the projecting
piece will not displace the valve until the bib cock is pressad inwards.
When this is
done the collar previously mentioned will enter the largest part of the bore of the
faucet and the packing ring will take its seating upon the end of the faucet and not
upon the end of the locking ring and valve chamber. A small catch is provided
upon the bib cock in such a position that when the bib cock is presseil inward as
far as desired this catch will enter a groove provided for it and prevent the outward
pressure upon the ball displacing the bib cock until it is desired to stop the outflow of
the liquid.
To provide for screwing instead of driving the taper, part of the faucet into the
cask or vessel, a thread is provided in the body of the faucet terminating against a
collar placed near to the outer screw. This collar may be hexagonal or square to fit
a spanner. The faucet may be thus screwed into the wood or into a metal tube
placed in the cask or vessel. These are alternative uses to which the faucet may
be put.
The invention is illustrated by the accompanying drawings in which similar letters
are used throughout the different views to indicate similar parts, and in which :-
Fig. 1 is an external view of the faucet or casing and air vent.
Fig. 2 is a screw cap used for protecting end when driving faucet into position.
Fig. 3 is a longitudinal section taken on the centre line of Fig. 1 shewing faucet,
air vent, inner valve chamber, and strainer or filter.
Fig. 4 is a cap and union or lining for forming connection to a beer engine
or pump.
Fig. 5 is the same view as Fig. 3, with the addition of a collar on the faucet to
enable it to be screwed into position instead of driven. The vent valve is not shown.
