COMPLETE SPECIFICATION.
Improvements in and connected with Draw Off Cocks and Ventilating
Arrangements for Beer and other Casks, Barrels, and the like.
1, JOHN FRANCIS, of Smithfield Terrace, Cwmillynfell, Swansea Valley, South
Wales, Engineman, 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 :-
The
My invention relates to draw off cocks for beer and other casks, barrels, and the
like, and the object is to prevent ingress of air when the tap is not in use.
invention is also applicable to the ventilating of casks and the like.
In carrying my invention into effect, I proceed in or in about the following manner,
making reference to the accompanying sheet of drawings, in which,
Fig. 1. is a longitudinal section of the whole appliance.
Fig. 2. a plan, and Fig. 3. a front elevation of the socket to be hereafter
referred to.
Fig. 4. a front view, and Fig. 5. a section of the end of the plug hereafter
mentioned, and
Fig. 6. a side view of the end of the tap shewing the slot in it.

My invention consists essentially of three main parts, the draw off cock or tap a ;
a socket screwing into the cask or like c; and a third portion a situated within the
cask or like. The cock a has its inlet end closed except for a slotted opening e
therein. The end is however perforated all round as at f, to allow the liquid to
flow in. Near the end are two projections g.
At a little distance from these is a
flange all round the tap end, and between g and his rubber or other washer i. The
socket bis tubular and flanged at one end ; and is screwed to receive the end of d.
The flange has two notches k into which can enter the projections g on the end of
the cock a.
These notches communicate with two helicoidal or bayonet joint slots
in the circumference of the socket b, so that by inserting the projections into the
notches k, and giving the cock a quarter turn to the right, the cock will he fixed and
the washer i squeezed between ; and h, thus forming an air-tight joint. The slots
may be made at an angle as shewn, so that when the tap is screwed in, the slots will
gradually draw h towards ; and thus more effectually squeeze the washer i between
them. The whole should be so arranged that the washer i will not touch the flange j
until the plug hereinafter mentioned has been rotated sufficiently to allow the liquid
to enter. The portion d consists of a tube m having a cap n screwed on its inner end.
The outer end is threaded to screw into the end of socket b. Quite close to the last
mentioned end, this tube m is bored out as a conical seating o, and an opening p is
made through the tube to allow the contents of the cask to flow in and this opening
can be covered with gauze p' or perforated plate. In the seating o I provide a hollow
conical plug the inner and larger end r of which is closed. In the side of
openings which on rotating q can be brought over the opening p in the seating o of
tube m.
Between the cap n and the closed end of 7 is a spiral spring t for keeping g
in the seating o.
The smaller end of 9 is open and across the opening is fastened a
metal star u and a little in advance of u is another star v, the points of which however
are over the spaces between the points of star u. In front of star v is a flat spigot w
of the same size as the slot e at the end of a. The star in conjunction with a
distance piece supports v, the star shape not interfering with the flow of the liquid
from 9. The star v, simply carries w, without obstructing the flow of the fluid to the

is an

in the socket b, the slot e goes over spigot w and on turning the cock to tighten it up
close to 6 by the slots 1, the plug 9 will be partly rotated in o, and bring the opening s
in the plug and that p in the seating, over one another and thus permit the liquid in
the cask to flow into q, through the stars u and r, and out into the tap by way of the
openings f. On opening the cock the liquid can be drawn off as required. On with-
drawing the tap, which can only be done by turning its projections g through the
slot 1, the slot e will turn the spigot wo and also the plug g, thus causing the opening s
to move from over the opening p in the seating o and thus shut off the supply of the
liquid. The tap may have a movable nozzle to direct the supply in any required
direction. The above arrangement may be used simply for ventilating casks and the
like in which case the tap is not needed, and the spigot w is turned by a key having a
notch in the end similar to e at the end of a.
I do not restrict myself to the precise shapes, relative proportions or disposition
of parts, as described or shewn, as any or all of them may be considerably varied
without departing from the spirit of my invention.
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 I
claim is;
CLAIMS.
1. The improvements in and connected with draw off cocks for beer and other casks
and the like, the said improvements consisting essentially of a flanged socket screwed
into the cask, the said socket having screwed into itself from inside the cask a tubular
casing. in a seating in which works a conical plug, having one end closed, and
having also in its circumference an opening, the said plug on insertion of the draw
off cock being caused to rotate in its seating in such a way as to bring its opening
over a hole in the seating, thus allowing the contents of the cask to flow into the
draw off cock, the withdrawal of the cock rotating the plug in the opposite direction
and so causing the holes to be no longer over each other and consequently cutting
off the flow of the liquid and preventing the ingress of air, the whole substantially
as described in the above specification and exemplified in the accompanying
drawings.
2. For ventilating casks and the like, an arrangement of parts similar to that which
is the subject matter of the above claim, but operated by the insertion of a suitably
shaped key instead of by the insertion of the draw off cock, substantially as described
in the above specification.
3. The combination of parts substantially as described in the above specification
and exemplified in the accompanying drawings, and operating either for the
prevention of the entry of air into, or for the ventilation of, casks and the like.
Dated this 13th day of January 1897.
