Improvements in Cones for Packing Taps in Beer Barrels and for
like Use, and in Means or Apparatus employed therein.
I ALFRED CANNON, of Sandford on Thames in the County of Oxford,
Paper Maker do hereby declare the nature of this invention to be as follows :-
This invention has reference to cones for packing around taps for beer barrels
and other like articles.
These have been made of india rubber and also have been produced by enwrapping
paper or strawboard to attain the required forms but these productions are costly
and imperfect,
The ordinary manner of packing a beer tap by means of a strip of brown paper
is, to say the least, unsatisfactory and requires considerable skill to effect the object
with neatness.
In carrying out my invention I form the packing cone (into which the spigot
end of the tap is to be passed and which cone is, in use, to lie wedged between the
tap and the sides of the hole in the barrel) as a coned short tube the interior
being coned to fit the coned spigot of the tap and the exterior is coned also to
wedge into the barrel tap hole, of pulp of the character of paper maker's or
board maker's pulp submitted in making to suitable consolidation, but without
winding.
These cones I form from pulp in a semi-liquid condition by inserting into a vessel
of such pulp a former, or series of formers, constructed of the contour of the
interior of the required pulp cone.
"
The side of the former is made of fine reticulate work-as fine brass wire cloth―
whilst the large end may be solid metal and the smaller end also solid around an
opening to which is connected a tube of rigid material to which may be connected a
flexible or other tube say of india rubber, which tube is connected to a vacuum or
partial vacuum chamber or pumping device. In order to produce on the "former
a thicker layer of pulp at and towards the thicker end of the same, the former
after insertion in the vessel of pulp and when it has by means of the suction, drawn
upon itself a layer of pulp suitable for the thinner end, is gradually raised out of
the vat so that as the operation of depositing pulp is allowed to continue, on less
and less an area, the deposit becomes thicker or coned towards the end longest
immersed.
Suitable pressure, trimming and finishing and sizing or dressing with preservative
or damp excluding liquid, is given according to circumstances.
A series of the formers may be actuated in a frame, by means of levers or arms
moved by cams or equivalent means, so as to insert the formers for the required
period to their full extent and gradually withdraw them to give the described
graduated dwell in the pulp vat and all simultaneously.
Dated the 2nd day of February 1894.

Improvements in Cones for Packing Taps in Beer Barrels and for
like Use, and in Means or Apparatus employed therein.
I ALFRED CANNON, of Sandford on Thames, in the County of Oxford, Paper
Maker 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 reference to cones for packing around taps for beer barrels
and other like articles.
These have been made of india rubber and also have been produced by enwrapping
paper or strawboard to attain the required forms but these productions are costly
and imperfect.
The ordinary manner of packing a beer tap by means of a strip of brown paper
is, to say the least, unsatisfactory and requires considerable skill to effect the object
with neatness.
In carrying out my invention supposing the particular use for which the packing
is designed, to be to fit a beer tap into a barrel I form the tube or cone (into which
the spigot end of the tap is to be passed and which cone is in use, to lie wedged
between the tap and the sides of the hole in the barrel) as a coned short tube, the
interior being coned to fit the coned spigot of the tap, and the exterior is coned
also to wedge into the barrel tap hole, of pulp of the character of paper makers'
or board makers' pulp submitted in making to suitable consolidation, but without
winding.
DESCRIPTION OF THE DRAWINGS.
Fig. 1 showe by a side view a ❝ former " upon which the packing cone is
produced.
Fig. 2 shows the same by a longitudinal sectional view and
Fig. 3 shows the "former" by a plan view.
Fig. 4 shows by a sectional view a vessel containing pulp in a semiliquid condition
and having a number of "formers "immersed therein.
The cones as here shown I form from pulp a in a semi liquid condition by
inserting into a vessel 6 of such pulp a "former' c or series of "formers," con-
structed of the contour of the interior of the required pulp cone. The side of
the "former" is made of fine reticulated work d-as fine brass wire cloth-,
supported by a suitable wire support d' in the form of a helix, whilst the
smaller end e may be solid metal and the larger end falso solid around an
opening g to which is connected a tube h of rigid material to which may be
connected a flexible or other tube say of india rubber, which tube is connected
to a vacuum or partial vacuum chamber or pumping device (not shown).
order to produce on the "former" c a thicker layer of pulp at and towards the
thicker end of the same, the "former," after insertion in the vessel of pulp and
when it has by means of the suction, drawn upon itself a layer of pulp suitable for
the thinner end, is gradually raised out of the vat so that as the operation of
depositing pulp is allowed to continue on less and less an area, the deposit
becomes thicker or coned towards the end longest immersed.
In
In some cases in place of forming the pulp in a shaped article upon the
exterior of a "former" it may be sucked against an interior surface or in place of
using suction I may employ pressure or both pressure and suction.
Suitable pressure, trimming and finishing and sizing or dressing with preservative
or damp excluding liquid is given according to circumstances.
A series of the "formers c may be actuated in a frame, by means of levers or

arms moved by cams or equivalent means, so as to insert the
"formers for the
required period to their full extent and gradually withdraw them to give the
described graduated dwell in the pulp vat and all simultaneously.
"
This frame and other of the parts may be modified to suit the number of articles
required to be immersed and the "formers may be varied in shape to adapt them
to produce the required configurations to obtain the required articles to be formed
such as packing cones, tubes and spool-tubes for spinners and the like as the
circumstances of the case may require.
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
1. The method of manufacturing cones or tubes for packing taps of barrels and
other like articles from paper or like pulp in a semi-liquid condition by suction or
pressure or a combination thereof onto a reticulate or perforate "former
substantially as set forth.
"
or model
2. The combination or arrangement and use of parts of apparatus for the
manufacture of cones or tubes for packing taps and other like articles from liquid
pulp with the aid of suction or pressure or a combination thereof substantially as
set forth.
