I JAMES RAPER THAME of 3 Winders Road, Battersea in the County of Surrey,
Engineer do hereby declare the nature of this invention to be as follows:-
The object of the present invention is the manufacture of seamless paper boxes
cases or enclosing receptacles for articles of various kinds such as gunpowder and
other goods.
In carrying out my invention I take a seamless tube of paper for which purpose I
find tubes produced according to the process and by apparatus such as is described in
the Provisional Specification left with my Application for Letters Patent of
August 8 1887 No. 10879 suitable, which said tube while in a moistened state I
place in a mould of the desired shape and insert within said tube a matrix or plunger
composed of one or more parts so arranged that they can be expanded or contracted
in various directions or a central matrix or plunger as above described may be used
and have the outer mould made of a number of parts so as to be readily expanded or
contracted, by the operation of one or both of the above moulds I cause the round
tube to assume the desired shape.
In some cases I use a central matrix or plunger having the top part made with
parallel sides and the lower portion prolonged of a conical or taper form. This
plunger may be in whole or part collapsible.
These moulds may be arranged with wire gauze, felt, or other suitable material
round them or may be made of fine wire backed with stronger material or they may
be made of perforated metal
The tops and bottoms of boxes made according to this invention 1 mould or block
in suitable moulds or it may be in the manner described for the blocking of the
bottoms and tops of barrels in the Provisional Specification left with my Application
for Patent aforesaid.

page_text: In some cases it is convenient to leave the seamless tube long enough to form
the bottom or top for the box or lid this prolongation of the tube serving to
form the bottom or top as the case may be on the application of suitably applied
pressure.

COMPLETE SPECIFICATION.
Improvements in the Manufacture of Paper Boxes, Cases, or
Receptacles, and in Means or Apparatus Employed therein.
I JAMES RAPER THAME of 3 Winders Road, Battersea, in the County of Surrey,
Engineer, 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 :-
The object of the present invention is the manufacture of seamless paper boxes,
cases, or enclosing receptacles for containing articles of various kinds to which such
are suited, such as for the packing of gunpowder, blasting powders and preparations
also for packing matches and other goods.
In carrying out my invention I take a seamless tube of paper, for which purpose I
find the tubes as produced according to the process and by apparatus such as is
described in the Provisional Specification and Complete Specification respectively
left with my application for Letters Patent dated the 8th day of August 1887
No. 10879 very suitable, which description of paper tube, while in its then wet or
moist condition, I place in a mould of the desired shape and I insert within the tube
a matrix or plunger composed of one or more parts so arranged that the several
divisions can be forced apart or expanded and reassembled or contracted in various
directions, or a central matrix or plunger, as above described, may be used and may
have the outer mould constructed as a number of parts so as to be capable of readily
being expanded or contracted.
By submitting such a wet paper tube to one or to both of such moulding devices,
I cause the round tube to assumie a square box shape or other desired form.
In some cases I employ a central matrix or plunger having the one part
made with parallel sides and the other part or portion prolonged of a conical
or tapered form.

page_text: Such a plunger may be in whole or in part collapsible.
These moulds may be arranged with wire gauze, felt, or other suitable material
around them, or may be made of fine wire work, backed with perforated work of
stronger material or texture, or the moulds may be made of perforated metal.
The tops or covers, and the bottoms or end covers, for boxes or cases made
according to this present invention. I mould or block to shape from moist paper
material, in suitable moulds similar to those described, only varied in arrangement
to the shapes required, or I manufacture them after the manner described for the
blocking of the bottoms and tops or end covers of barrels set forth in the Specification
of Patent aforementioned.
In some cases it is convenient to leave the moist seamless tube of paper
sufficient in length to permit of the end or bottom of the box, or top of a lid, as
the case may be, to be formed from such extra length of moist tubular paper
material, by applying a correspondingly shaped pressing part to crush the mass
into a homogeneous solid surface.
DESCRIPTION OF THE DRAWINGS.
Fig. 1 is a side view partly in section of an arrangement of mechanism adapted to
press a wet cylindrical tube, of the kind described, into a rectangular box form,
leaving it without an end, or with material adapted to be pressed into a closed end.
One side (in said Figure) of the expansible slides is removed.
Fig. 2 is a plan view of Figure 1.
Fig. 3 is a vertical section on the line A A. of Fig. 4, of such an arrangement of
internal expansible plunger or former as is adapted to operate within the shape operated
on by the external parts illustrated by Figs. 1 and 2, except that size of the square
would be reduced to that of the block within Figs. 1 and 2.
Fig. 4 shews a plan view of Fig. 3.
Fig. 5 is a plan view of a tube such as could be treated and blocked to a square
shape, such as represented by Fig. 6, which square would be that represented by the
block in Fig. 1.
Fig. 7 shews by a side view partly in section a modification of the arrangement
shewn by Fig. 1 in which the arrangement of the screws for operating the slides d,d d' d'
is varied.
.
Fig. 8 is a plan view of Fig. 7.
Fig 9 is a vertical section of a central matrix having the lower part with parallel
sides and the upper portion prolonged of a taper form.
Fig. 10 is a cross section on the line A B of Fig. 9.
This arrangement shown by these Figures 7 & 8 only differs in the mode in which
the screw pressure is transmitted, in Figs. 1 & 2 as will be described the operating
screws are arranged below the platform whereas in Figs. 7 & 8 the axes are divided,
thus the axis e* operated for rotation by suitable power represented by the handle
wheel has mounted on it tooth wheels e which gear with intermediate wheels et
which engage other tooth wheels e which give rotation to the screw axes e to cause
the slides d, d. d, d¹ to work to and fro.
a represents a central former of reticulate metal or reticulate metal covered with
wire gauze, as represented by a portion at b, the rest of the cover of a being supposed
to be broken away.
This former a is affixed to the platform c, or may be carried by a
central stem, as hereafter described in respect of Fig. 3, the sides being expansible.
d, d, d, dare the movable sides for blocking the exterior of a tube of wet paper
material placed over block a supported on slides d², d², d³, d³ respectively, and
traversing between guides d'. These sliding movable sides dd, d¹ d¹ are respectively
moved by screw axes e, e, e¹, e¹ turning loosely in bearings c', et affixed to the platform
and other similar bearings, on extensions of the platform not shewn. These shafts
are turned by suitable pulleys adapted to receive bands driven by suitable power
represented in the drawing by hand pulleys which for adjusting purposes may be
added and the screw threads on these shafts engage corresponding threads formed in
C

page_text: the lugs d, carried down through the platform c. ffff are four divisions of the
central plunger or former capable of sliding out in radial directions on the supporting
cam and guideways g, g, on the platform. These divisions provided with studs * top
and bottom, which studs pass into curved eccentric grooves in the wider portion of
the double cams, the narrower portions of these cams being adapted only to press
out the divisions to the positions indicated by the dotted lines. These cams are
mounted on, and rotated by, the central shaft * mounted at foot in the base plate c,
and above in suitable framing, not shewn, as it may be of any ordinary description
and the means of causing rotation of the shaft ³ may be by any ordinary and
suitable gearing. As the inner cams 2 are only provided for greater strength in the
thrusting motion they can be suppressed, and the slotted plate / perform the double
operation, or the cams 2 may alone be used to expand the division, and spring parts
may retract the pins and their divisions.
In reference to Figs. 9 and 10 the form of central matrix or former a is varied in
that the sides of the parallel portions f,ff, f³ are capable of being somewhat
projected and of being retracted by the links or arms i hinged to those sides and to a
central block having a screwed socket in which engages a screw ho formed on the
vertical axis ³ which axis may be rotated by means of power applied at the exterior of
the axis as by the handle wheel . are tie rods between the platform c and the
head of the matrix h.
The tube of pulp having been placed over this matrix or central former, the sides
may be protruded by rotating the axis h³ and by the screw 5 lowering the block *
thereon bringing the links into a horizontal position and to retract them the reverse
movement is made.
This former a may be used in conjunction with the external shaping means d, d. d¹ d'.
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
In the manufacture of boxes, cases or other receptacles for gunpowder or other
uses the production of square or other angularly shaped forms from wet or moist paper
material by the aid of expansible and retractible moulds or matrices and corre-
spondingly expansible and retractible plungers, separately used, or in combination as
set forth.
