PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Flower Pots, Tobacco Jars,
Bowls, and other Hollow Articles.
I, FREDERICK HANDEL MILLINGTON, of Thetford, in the County of Norfolk,
Manager and Secretary to the Patent Pulp Manufacturing Company, Limited do
hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in the manufacture of flower pots, tobacco
jars, bowls and other hollow articles and has for its object to obtain an attractive
appearance combined with lightness and durability.
I
For this purpose, employ a hollow plug or mould of perforated metal, and of
the shape desired to be given to the interior of the article to be produced and I fix
this hollow plug or mould in a suitable vessel and then fill into the said vessel
around the outside of the hollow plug or mould, a given quantity of paper pulp,
wood fibre, wood pulp, or other suitable vegetable fibre and I then by exhausting
the air from the inside of the hollow plug remove the water from the pulp, or, in
some cases, I employ a closed outer vessel and introduce compressed air therein in
lieu of or in addition to exhausting the air from the hollow plug. The air exhaust
is controlled by suitable means and the pulp is deposited in a semi-dry state upon
the perforated plug or mould in varying thickness which gives the exterior of the
finished article the appearance of bark or virgin cork. When the required
appearance and thickness are attained the article is removed from the plug or mould
and placed in a drying room or stove where it is allowed to remain until all the
moisture is evaporated from the pulp or fibre. The article is then waterproofed by
means of boiled linseed oil, varnish, or other suitable material, previous to which it
may, if desired, be colored by the aid of dye or other material.
By these means, we obtain an inexpensive flower pot or other hollow article the
exterior of which has the attractive appearance of virgin cork or bark whilst the
interior thereof has a smooth surface thus adapting it to various useful purposes for
which more costly and less attractive articles are at present employed.

COMPLETE SPECIFICATION.
Improvements in the Manufacture of Flower Pots, Tobacco Jars,
Bowls, and other Hollow Articles.
I, FREDERICK HANDEL MILLINGTON, of Thetford, in the County of Norfolk,
Manager and Secretary to the Patent Pulp Manufacturing Company, Limited, 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, reference being had to the drawing hereunto annexed and to the figures
and letters marked thereon, that is to say :-
My said invention relates to improvements in the manufacture of flower pots,
tobacco jars, bowls, and other hollow articles, and has for its object to obtain an
attractive appearance combined with lightness and durability.
For this purpose, I employ a hollow plug or mould a of perforated metal,
preferably copper, formed with a rim a' and of the shape desired to be given to the
interior of the article to be produced, and I envelop the mould in a covering a* of
wire gauze which is securely fixed thereto.

page_text: The hollow plug or mould a. I fix in an inverted position in a suitable open
vessel b. also formed preferably of copper, and around the plug a. and resting upon
the rim a', I place a loose ring or lifter c. provided with handles c'. I then fill into
the said vessel b. around the outside of the hollow plug or mould a., a given quantity
of paper pulp, wood fibre, wood pulp, or the pulp of other suitable vegetable fibre
until the vessel . is full, and I then exhaust the air from the inside of the hollow
plug through a pipe and thus remove the water from the pulp, or,
in some
cases, I close the outer vessel b. by means of a cover 3 as shown by the dotted lines
and introduce compressed air therein through a supply pipe 63* in lieu of, or in
addition to, exhausting the air from the hollow plug a.
The air exhaust 6' is controlled by a cork and the pulp d. is deposited in a semi-
dry state upon the perforated plug or mould a. in the manner represented in the
drawing, and by reason of the great thickness and unequal density of the pulp
coupled with the irregular channel by which the water finds its exit therefrom, it is
deposited in varying thickness, which gives the exterior of the finished article the
appearance of bark or virgin cork.
When the required appearance and thickness are attained, a current of air is
forced into the mould a. through the pipe to free the article therefrom, and it is
then easily removed from the plug or mould .. .. by means of the lifter c. and placed
in a drying room or stove where it is allowed to remain until all the moisture is
evaporated from the pulp or fibre.
The article is then waterproofed by means of boiled linseed oil, varnish or other
suitable material, previous to which, it may, if desired, be colored by the aid of dye
or other material.
By these means, I obtain an inexpensive flower pot or other hollow article, the
exterior of which has the attractive appearance of virgin cork or bark, whilst the
interior thereof has a comparatively smooth surface, thus adapting it to various
useful purposes for which more costly and less attractive articles are at present
employed.
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
The manufacture of flower pots and various other hollow articles, with an exterior
surface resembling virgin cork or bark by depositing a considerable thickness of the
pulp of paper or other suitable material upon the exterior of a hollow perforated
mould of the shape desired to be given to the interior of the article and then
exhausting the air from the interior or compressing air upon the exterior thereof, or
both combined, in manner substantially as herein shown and described and for the
purpose stated.
