page_text: I, VICTOR PERRETT, of Union Brewery, Wandsworth, in the County of London,
Brewer, do hereby declare the nature of my invention to be as follows:-
My invention relates, principally, to such taps as have the body of the tap made
in one piece with the body of the jar, cask, or the like, with a vertical hole therein
for the plug of the valve, the said hole being at, or about, right angles with the
hole which gives communication through the valve body from the interior of the
jar, cask, or the like, to the plug of the tap, which plug is provided with a vertical
passage opening at its lower end and communicating with a sideway opening
through the plug which sideway opening can be brought opposite the passage from
the interior of the jar, cask, or the like, and away from it to draw off, and to close
the outlet, as required. There is, usually a bushing of cork, or other material,
between the body and plug of the tap. Taps as hitherto constructed in this
'manner are very liable to leak, owing, principally, to the packing material
becoming damp and swelling, and afterwards drying and contracting, and it is
the object of my invention to overcome this objection, which I effect by providing
packing material only around the orifice of the body of the tap, which leads into
the jar, cask, or the like, or on the side of the plug presented towards the
jar, cask, or the like, the space between the plug and the body of the tap at
the opposite side having a wedging piece or pieces inserted thereinto, which can
be readily driven in to compensate for any contraction of the packing material
which may occur. I do not limit myself to the precise shape, or arrangement, of
the packing piece, or wedge, but they may conveniently be made each of, or about,
a quarter of a circle in horizontal section.
My invention is not limited in its application to the taps of jars, casks or the like
of the kind described as it can be applied to any hollow tap with an outlet beneath
and bushed with a material which is alterable in bulk such as cork, rubber or the
like.

I, VICTOR PERRETT, of Union Brewery, Wandsworth, in the County of London,
Brewer, do hereby declare the nature of this invention and in what manner the
Price 8d]

page_text: same is to be performed to be particularly described and ascertained in and by the
following statement:-
My invention relates principally to such taps as have the body of the tap made
in one piece with the body of the jar, cask or the like, with a vertical hole therein
for the plug of the tap, the said hole being at, or about, right angles with the
hole which gives communication through the tap body from the interior of the
jar, cask, or the like, to the plug of the tap, which plug is provided with a vertical
passage opening at its lower end and communicating with a sideway opening
through the plug which sideway opening can be brought opposite the passage from
the interior of the jar, cask or the like, and away from it to draw off, and to close
the outlet as required. There is usually a bushing of cork, or other material,
between the body and the plug of the tap. Taps as hitherto constructed in this
manner are very liable to leak, owing principally, to the packing material
becoming damp and swelling and afterwards drying and contracting, and it is
the object of my invention to overcome this objection, which I effect by providing
packing material which is preferably only situated around the orifice in the body
of the tap, which leads into the jar, cask or the like, or on the side of the plug
presented towards the jar, cask or the like, the space behind the plug, that
is, at the opposite side thereof having a wedging piece, or pieces, inserted thereinto,
which can be readily driven in to compensate for any contraction of the packing
material which may occur.
I have illustrated in the accompanying drawing an arrangement according to
my invention Figure 1 being a vertical section and Figure 2 a horizontal section of
a part of a jar or receptacle of earthenware, glass or the like with the part A con-
stituting the body of the tap formed in one therewith. In it is formed a vertical
hole for the insertion of the plug B of the tap a horizontal hole a forming a
communication from the interior of the jar or receptacle to the hole 6 in the
plug B which communicates with the outlet orifice in the axis of the plug. I do
not limit myself to the precise shape, or arrangement, of the packing piece, and
wedge, but they are preferably made as shewn in the drawing that is to say the
packing piece C is segmental and extends about half way round the vertical hole
and plug B and the wedge D is of about the width shewn. It is situated at the side
of the plug B opposite to the packing piece C.

By making the packing as described and fitting it into a recessed portion in
the part A constituting the body of the tap, the said packing is prevented from
turning with the plug of the tap by the shoulders of the said recessed part. The
said part A is preferably made of a size so that the plug B of the tap fits loosely
therein save where in contact on the one side with the aforesaid bushing or pack-
ing C and on the other side with the wedge D. An air space E (Figure 2) is thus
preferably provided on each side between the plug and the body part A of the tap;
by this means air can enter by the hole into the plug B after it has passed the
packing and dripping is prevented; sticking between the parts is by this means
also avoided. The piece 62 secured to the plug B constitutes a stop for limiting
the movement of the plug B when it arrives at its open and its closed positions
respectively.
In place of one wedging piece C I may use more than one piece if desired. My
invention is not limited in its application to the taps of jars, casks or the like of
the kind described as it can be applied to any hollow tap with an outlet beneath and
bushed with a material which is alterable in bulk such as cork, rubber, or the like.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I declare that what I claim is :-
1. The combination with a tap body having a vertical hole and a hollow plug
working therein, of a wedging piece (or pieces) such as D for forcing the plug
of the tap to a close bearing against the side whereat the fluid passes through
the tap when it is open substantially as hereinbefore described.

page_text: 2. A tap body formed with a vertical opening containing the plug and provided
with a bushing or packing at the side next the outlet orifice and at the opposite
side of the plug with a wedging piece or wedging pieces substantially as and
for the purposes herein before described.
