Improvements in Means or Apparatus for the Manufacture of Barrels
or other like Forms from Pulp.
We HENRY MCKEONE of 5 Westminster Chambers, Victoria Street in the City
of Westminster, Engineer and Contractor, JAMES RAPER THAME of Two Waters
Mill, Boxmoor in the County of Herts, Engineer, and HERBERT SANGUINETTI of
Amber House, St. Johns Wood Road, Regents Park in the County of Middlesex,
Gentleman, do hereby declare the nature of this invention to be as follows:-
This invention has for its object the further development of the improved
manufacture of barrels and other like forms from pulp described in the Specification
of Letters Patent granted to James Raper Thame dated the 9th January 1888
No. 346 so as to enable bilged barrels and the like to be made on the forming rolls
by winding on semi-liquid pulp.
The forming rolls employed are made collapsible in the direction of their centre
or so as to become sufficiently reduced in diameter to admit of the parts that have
supported and given form to the pulp during manufacture substantially as set forth
in the said Specification. This collapsing of the rolls may be obtained by a variety
of methods of connecting and operating sections of the forming rolls. The rolls
may consist each of four or other number of hinged or connected part rolls so
mounted that on withdrawal of one division or key part the others are brought in or
fall together.
Or the bilged collapsing roll may be arranged to slide on a rotating or other
supporting means and after withdrawal of the grooved key or slide which may be
in two or more parts the bilged roll can be drawn off and collapsed by any suitable
mechanical means, or the parts forming said roll may be fixed to an inner or
supporting frame, disc or chuck capable of contraction and expansion by screw cam
or hydraulic means.
This may be attained by the divisions of the rolls collapsing on the end of the
barrel shape, or by a movement of the parts parallel relatively to the line of the
axis.
The collapsing of the parts on centres borne by one end piece of the rotating
frame may be controlled by a sliding plate, a cam, or inclined groove engaging
studs operating connections to the sections.
For the collapsing of the sections by motions parallel to the axis of the cylinder
a sliding or rotating bar or axis carrying inclines or wedging parts controlling the
sections and preferably with a wedging section acting to key the whole tightly into
the perfect bilged forming roller.
The wedging section may be linked to or mounted on hinges or arms from a
central or other axis or slide or in equivalent manner brought in and out of position
for completing the circle and its movement also controls the movements of the other
sections.
Also the invention relates to the construction of a bilged making roll composed
of woodite, vulcanised rubber or other compressible material, to be compressed into
the desired shape by any suitable mechanical or other means so as to allow of the
said making roll by the releasing of the said pressure assuming its normal shape in
order to permit of the withdrawal of the manufactured barrel tube in its bilged
shape or condition.
Dated the 28th day of March 1800.

Improvements in Means or Apparatus for the Manufacture of Barrels
or other like Forms from Pulp.
We, HENRY MCKEONE of 5 Westminster Chambers, Victoria Street in the City
of Westminster, Engineer and Contractor, JAMES RAPER THAME of Two Waters
Mill, Boxmoor, in the County of Herts, Engineer and HERBERT SANGUINETTI of
Amber House, St. Johns Wood Road, Regents Park in the County of Middlesex,
Gentleman, 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 for its object the further development of the improved
manufacture of barrels and other like forms from pulp described in the Specification
of Letters Patent granted to James Raper Thame dated the 9th January 1888
No. 346 so as to enable bilged barrels and the like to be made on the forming rolls
by winding on semi-liquid pulp.
The forming rolls employed are made collapsible in the direction of their centre
line or so as to become sufficiently reduced in diameter to admit of the parts that
have supported and given form to the pulp during manufacture being withdrawn,
substantially as set forth in the said Specification.
This collapsing of the rolls may be obtained by a variety of methods of connecting
and operating sections of the forming rolls.
The rolls may consist each of four or other number of hinged or connected part
rolls so mounted that on withdrawal of one division or key part the others are
brought in or fall together.
Or, the bilged collapsing roll may be arranged to slide on a rotating or other
supporting means and after withdrawal of the grooved key or slide which may be
in two or more parts the bilged roll can be drawn off and collapsed by any suitable
mechanical means, or the parts forming said roll may be fixed to an inner or
supporting frame, disc or chuck capable of contraction and expansion by screw cam
or hydraulic means.
This may be attained by the divisions of the rolls collapsing on the end of the
barrel shape, or by a movement of the parts parallel relatively to the line of the
axis.
The collapsing of the parts on centres borne by one end piece of the rotating
frame may be controlled by a sliding plate, a cam, or inclined groove engaging
studs operating connections to the sections.
For the collapsing of the sections by motions parallel to the axis of the cylinder
a sliding or rotating bar or axis carrying inclines or wedging parts controlling the
sections and preferably with a wedging section acting to key the whole tightly into
the perfect bilged forming roller.
The wedging section may be linked to or mounted on hinges or arms from a
central or other axis or slide or in equivalent manner brought in and out of position
for completing the circle and its movement also controlling the movements of the
other sections.
Also the invention relates to the construction of a bilged making roll composed of
woodite, vulcanised rubber or other compressible material, to be compressed into
the desired shape by any suitable mechanical or other means so as to allow of the
said making roll by the releasing of the said pressure assuming its normal shape in
order to permit of the withdrawal of the manufactured barrel tube in its bilged
shape or condition.

indicate the lines of traverse of the extremities of the leaves a¹, a².
Figure 3 shows by a longitudinal sectional view and Fig. 4 by an end view a
modification of the arrangements for enabling the bilged roll or shell to be reduced
in size to release it from the formed pulp article.
Figure 5 is a plan view of the inner roll or cylinder 6 showing the keyways b' b
on which the projections or wedge shaped tongue pieces c', c', attached to the outer
(say brass) shell c, slide and by which their motion is controlled. d is a slide or
filling piece running at each edge in a locking groove d' in the outer shell c.
The keyways b', 6' are formed in the part 2 of the roll b which part may be
attached by screwing to the part mounted fixedly on the axis e. On this axis e is
also mounted loosely the wheelf having on its periphery the inclined fin f' which
fin engages the lugs (one of which is seen in Figure 3) formed on the end of each
tongue piece c' and serves to draw and force these pieces c¹ and with them the shell e
to and fro and by such movement to tighten and hold the parts. This wheelf may
be turned by levers inserted in holes formed therein. is another lug on the
shell c and engaged by the inclined fin f1 to press the shell to its place.
In use for enwrapping with pulp the shell with the slide d form one continuous
bilged contour, but for withdrawal the slide is drawn out from the shell c and the
shell released from the grooves is collapsed and withdrawn from the pulp form.
Figure 6 shows another modification of the apparatus in which the shell a is
formed of india rubber or woodite or like suitably elastic material and this shell can
be transformed in contour from a plain cylinder as indicated by the full lines to a
bilged form as indicated by the dotted lines by traversing the nuts 6* on the screwed
threads of the central shaft e towards the centre of the roll and the reverse operation
can be performed by reversing the screwing of the nuts.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is:
1. The combination or arrangement and use of means or apparatus for the manu-
facture of bilged barrels or other like bilged forms from paper or similar pulp
substantially as set forth.
2. In means or apparatus for the manufacture of barrels or other like forms, from
paper, or other similar, pulp, the combination or arrangements of parts as set forth
in respect of Figures 1 and 2.
3. In means or apparatus for the manufacture of bilged barrels or other bilged
forms from pulp the combination of parts as set forth in respect of Figures 3, 4
and 5.
4. In means or apparatus for the manufacture of bilged barrels or other bilged
forms from pulp the combination of parts as set forth in respect of Figure 6.
