PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Casks and in the Apparatus
employed in their Manufacture.
I, ALFRED SCHOTT of 15 Peterboro' Lane, Parsons Green London in the
County of Middlesex do hereby declare the nature of this invention to be as
follows:-
This invention relates to the manufacture of casks, for dry or wet goods, said
casks being made from any suitable kind of pulped fibrous materials.
In carrying out this invention, I take pulp, prepared from say, waste paper for
cheapness & run the same on to a machine, said machine being composed of suitably
shaped & constructed moulds carried by any suitable means such as chains, ropes
belts or similar means, said chains, ropes, belts, &c. with the above named moulds
being driven or moved by means of suitable chain rope or belt wheels or pulleys
fixed on shafts and carried by suitable frames & connected with & worked by
suitable gearing, driving pulley &c. This machine is so arranged that one of the
moulds after being filled with the requisite amount of pulp is, by means of the
herein mentioned driving gear caused to travel a certain distance to enable it to
come under a press head, at the same time another mould is brought forward for
filling with pulp, the press head may be worked by steam, screw, hydraulic er
other means, the pressure being applied to the pulp contained in the said mould,
which during the pressing operation, is caused to rest on a block or frame suitably
constructed to allow the water to escape freely from the pulp after pressing the
mould with its pressed & partially dry pulp form is removed, the pulp form taken
out & the mould replaced on the machine.
The pulp form herein referred to in this invention being of the necessary form
& shape for a cask or barrel stave, the edges of said stave may be formed during
the above named moulding operation or by an after process, with grooves, splayed
edges, tongue or other projections necessary to ensure perfectly tight joints between
such staves when set up or made into a barrel or cask. The head & bottom for
such barrel or casks may be composed of the same material as the staves & may
be made or moulded in a similar machine as described herein for the manufacture
of cask staves.
The grooves at each end of the staves necessary for holding the ends in place
may be produced while the staves are being moulded or by an after pressing or
cutting operation.
The setting up of such staves into barrels i.e., the trussing &c. may be done in
the usual way common to wooden staves.
Staves made from fibrous pulped materials as herein described after being dried
or dessicated may be treated with any suitable material to render them water
proof &c.

Improvements in the Manufacture of Casks and in the Apparatus
employed in their Manufacture.
I ALFRED SCHOTT of 19 Peterborough Lane Parsons Green London in the
County of Middlesex 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 relates to the manufacture of casks for dry and wet goods,
from any suitable kind of pulped fibrous material.
In carrying out this invention I take pulp prepared from say waste paper for
cheapness & run same on to a machine, said machine having a number of moulds
of the desired shape, these moulds are carried by chains ropes or other means, the
machine being driven by pulleys, gearing etc., whereby it is automatically stopped
when required to enable the pulp contained in the moulds to be pressed, the driving
mechanism of the machine being so arranged that after the pressing has taken
place the mould will travel on, & the barrel stave or other form contained in the
inould will be automatically ejected.
The barrel staves or other forms so made are next placed in a suitable
hydraulic or other press & submitted to a pressure of from 50 to 100 tons, after
being dried the staves are treated with a suitable waterproofing agent & are then
ready to be made up into casks.
To enable the barrel staves so produced to be set up cheaply & expeditiously I
make use of an expanding & contracting core made as follows vic. I take a vertical
shaft which is fixed in a sole plate on the floor or bench. On this shaft are two
discs one at each end the lower one being keyed to the shaft, around the periphery
of the two discs I fix a number of metallic strips, said strips being somewhat
longer than the barrel to be made, the top disc is so arranged that by means of a
nut it can be drawn up & down on the vertical shaft.
The barrel staves are arranged round the said contracting core & held in place
by an iron or other hoop the top disc being then screwed down causes the metallic
strips to assume a bent shape largest in the centre & to suit themselves to the shape
of the barrel staves which can then be hooped up ready for the ends to be put in
to enable the bulged barrel shell to be withdrawn from the core the top disc of core
is screwed up & the strips brought to a vertical position, the cask is then taken off
& finished.
DESCRIPTION OF THE DRAWING.
The drawing shows by a side elevation & part section, the apparatus designed
to carry out the manufacture of barrel staves as herein described A represents the
pulp container or chest B being an agitator worked by shaft C, D is the outlet
from A to mould W of which E is a moveable metal or wood side, E being a wire
covered bottom of perforated metal or wood the bottom F is fitted with trunnions
working in chain attachment I said chain attachment forming part of driving or
carrying chain 1'. The mould after being filled with pulp is by means of the strap
driven pulley M & gear wheel O working into gear wheel P & chain wheel R carried
on until it arrives over table or pressing plate J & under press head H the wheel O
then ceases to drive P by reason of half its teeth being cut away, the mould
containing the pulp G now receives the necessary pressure from press plunger H
which can be worked by hydraulic or other means, the mould with its pressed &
now partially dried pulp barrel stave is carried by the chain I¹ over wheel T fixed
on shaft U & supported by frame V & on arriving over the centre of shaft U can
be lifted off the attachment I or be allowed to drop on to a truck or table.
Barrel staves so made may have their edges grooved & tongued, halved, splayed
or otherwise shaped to ensure tight joints when set up.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion & in what manner the same is to be performed I declare that what I
claim is―
1. The manufacture of casks composed of staves made from paper or other
vegetable pulped fibrous material.
2. The manufacture of cask staves from paper or other vegetable pulped fibrous
material by moulding & pressing substantially as herein described.
3. Cask staves made from paper or other vegetable pulped fibrous material said
staves having their edges tongued & grooved, halved or splayed.
