I, WILLIAM PHILLIPS THOMPSON Fel. Inst. P. A. of the Agency for Foreign
Patent Solicitors 6, Lord Street Liverpool, in' the County of Lancaster and
323 High Holborn in the County of Middlesex, Civil Engineer do hereby declare
the nature of this invention (a Communication from abroad by Julius Geiger of
Stuttgart in the Empire of Germany, Manufacturer), and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement:―
The construction of composite boxes, and the like out of cardboard of various
kinds and qualities, has hitherto been effected by preparing the pieces of cardboard
by nicking or cutting along the lines of the outer edges or by cutting them away
on the inside ones; both these processes diminish the strength of the box very
seriously, because the thickness of the cardboard is greatly reduced at these
points.
Now by this invention by means of the pressing in of grooves or depressions in
the cardboard, either in the cold or preferably when heated according as the
material requires that in the first place the full strength of the cardboard is
preserved, and moreover that these grooves or depressions can be rolled not only
in the rough state, but also when finished and covered with the finest satin-paper,
art-paper, or leather-paper, or other decorative material without risking a fracture
of the material outside or in.
In the accompanying drawing
Figures 1 to 4 shew the rolling machine by means of which the bending of
the material or rather the rolling of the grooves in the same is preferably
accomplished.
Upon the frame a, a, are placed two rolls b and c in such a manner that they
can be adjusted by means of the screw f and spring g, upon these rolls are placed
loosely the two discs d and e, which can be fixed by the screws 1, 1, upon b and c.
The divided rings k, k, are designed to impress in the cardboard the grooves
required, and are of any required shape according to the size or depth of the

page_text: grooves required in the material. These rings are fixed by means of screws i, i,
in their proper places upon the discs d and e. Upon the support o rests the table n
from off which the materials to be operated on are fed between guides m, m,
between the rolls and discs.
In order to heat the rolls and the cardboard passing between them, the gaspipe h
provided with small burners is passed into the hollow rolls b and c. To make
cardboard boxes and the like the sides of which are not held together by glueing
or sewing, but by metallic connecting pieces, the cardboard to be used receives the
shape shown in Figure 5:
་
Grooves are impressed on the inner side by means of the rings h, k, and the
side pieces are cut or slit at p, p. Figures 7 and 8 shew the metal clamps serving
to unite the side pieces, the side claws 8, 8, of which (Figure 6) are bent over
mechanically and inserted in the slits p, p, and clinched on the inside. A finished
box is shown in Figure 9. The metal clips may have any desired shape or pattern
according to requirements and are provided with a number, proportioned to their
size of side projections 8, 8, and according as they are designed for the lid (Figure 8)
or for the lower part of the box (Figure 7).
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, I declare that what
I claim is
1. The impressing of grooves or hollows in cardboard pieces, with or without
application of heat, in the process of manufacturing boxes and the like.
2. A roller apparatus designed for the impressing of grooves of any required
section in cardboard provided with the discs d, e, with changeable impressing
rings k, k, and with hollow cylinders b, c, provided with a heating arrangement.
3: In the construction of composite boxes and the like from cardboard and
similar materials the use of the metal clamps r, r, for uniting the sides, by means
of the slits p, p, and the projections 8, 8, pushed through the said slits and clenched
inside.
