Improvements in Machines for the Manufacture of Paper, Pasteboard,
Thin Wood, or other Flexible Folded Boxes.
We, ARTHUR BUCKLEY WEBB and JOHN WATSON of the Globe Works, Factory
Fold, Hollinwood Engineers do hereby declare the nature of this invention to be as
follows:-
Our invention applies to machines for the manufacture of flexible folded boxes of.
the form as described in Specification No. 1931 A.D. 1874, & consists of a new
arrangement of the punching heads & parts, whereby the adjustment of the punches
& dies is simply & quickly effected, so that one set of dies supplied with the machine
will suffice for various sizes of boxes.
In this machine we use four punching heads, consisting of the punching ram
guides and the bases upon which the die plates are secured, so arranged as to secure
perfect truth between the punches & dies. These have each lateral adjustment for
varying sizes of boxes, & slide in a groove in the back plate of the machine, being
secured, when set, by suitable set screws.
Blanks of the required size are prepared & are placed on the machine, from the
front, by hand, suitable guides marking the exact position for placing. The punches
are actuated by a solid eccentric shaft extending the whole width of the machine
so that, when the punching heads are being set, the rods for working the rams
simply slide along the shaft, & need no uncoupling.
The adjustment for varying the length of cut of the punches & dies is obtained
as follows:-
-
The punches employed for forming the tongues of the boxes are made in two
parts, one portion, forming the tongue proper, being a fixture, the other portion,
for cutting the slot, so arranged as to slide between this fixed portion and the punch
holder making the cut longer or shorter as required. The other punches are made in
a single piece & long enough for the longest slot which the machine will be required
to cut. For other sizes part of the punch is allowed to project beyond the blank
which is being operated upon, this projecting portion being greater or less according
as the slot being cut is less or greater.
The dies at bottom are also made to project beyond the blank, & are in two
pieces, one of which is formed in the shape of an inverted L, with a longitudinal
slot cut in the perpendicular leg, through which screws pass for securing this
portion in position. The other portion is fixed. This movement of the die plate is
to allow the bottom die to be set to correspond with the punch above, making a
longer or shorter slot as required.

We ARTHUR BUCKLEY WEBB and JOHN WATSON of the Globe Works Factory
Fold, Hollinwood Engineers 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 :-
Our Invention applies to machines for the manufacture of flexible folded boxes
of the form described in the Specification No. 1931 A.D. 1874 and consists of a new

page_text: arrangement of the punching heads and parts whereby the adjustment of the punches
and dies is simply and quickly effected so that one set of dies supplied with the
machine will suffice for various sizes of boxes..
In this machine we use four punching heads consisting of the punchingram guides
and the bases upon which the,die plates are secured so arranged as to secure perfect
truth between the punches and dies. These have each lateral adjustment for varying
sizes of boxes and slide in a groove in the back plate of the machine being secured “
when set by suitable set screws.
Blanks of the required size are prepared and are placed on the machine from the
front by hand suitable guides marking the exact position for placing. The punches
are actuated by a solid eccentric shaft extending the whole width of the machine so
that when the punching heads are being set the rods for working the rams simply slide
along the shaft and need no uncoupling.
Both the punches and the dies are adjustable for varying the length of cut.
In order that our said Invention may be fully understood and readily carried into
effect we will proceed to describe the drawings hereunto annexed.
DESCRIPTION OF THE DRAWINGS.
Figure 1 shows a piece of cardboard cut suitably for folding into a box as described
in the Specification No. 1931 A.D. 1874.
Figure 2 shows part of a piece similarly cut to form a box of larger size and of
different proportions.
Figure 3 is a front elevation of a machine for punching or shaping the ends of the
cardboard. This machine is made in accordance with our Invention and can be
adjusted to cut either of the forms above shown, and other similar forms suitable to
make boxes of many sizes and various proportions.
Figure 4 is an end elevation of the machine.
Figure 5 is a side elevation to a larger scale of one of the punching heads but
without the punches and dies.
Figure 6 is a section on the line 6. 6 in Figure 5.
Figure 7 is a section on the line 7. 7. in Figure 5.
Figure 8 is a section on the line 8. 8. in Figure 5, in this figure the lower dies
or die plates are shown in place.
Figures 9. 10 and.11 are similar to Figure . these four figures show the arrange-
ment of the dies upon the several punching heads forming the series of heads which
operate: simultaneously upon the cardboard or material..
Figures 12. 13. 14 and 15 show front elevations of the corresponding punches
together with the lower end of the punching rams by which the same are carried.
Figures 16. 17. 18 and 19 show horizontal sections on the lines 16. 16. 17. 17.
18..18 and 19. 19. in the Figures 12, 13, 14 and 15 respectively.
a a are base frames on which a table is carried; also standards c.c and a back
plate d.
In the. back plate d is a longitudinal slot d eeee are the punching-heads, they
stand 'upon the table band an enlargement el upon each enters the slot d'. In the
said enlargement also there is a tapped hole which receives a bolt passing through
the slot and serving to clamp the head to the back plate in any required position.
999, 9 are punching rams working up and down in guides in the heads e; they
receive movement through connecting rods h, h, h, h from. ther shaft i. which is
turned eccentric to. the necks at its ends. The shaft is carried in bearings
upon the standards.c cand upon one of the necks is a.spur, wheel:k.. The wheelk
gears with a pinion. on a shaft I also carried in bearings on the standards.c. are
belt pulleys on the shaft by, which the machine is driven. When the eccentric.
shaft or continuous eccentric is rotated, it imparts a reciprocating movement to the.
ramis g
The base of each head e carries the lower dies in figures 8, 9. 10 and 11 these
are marked m³, m², m³; m², m³, m³, m², and m³. The dies are angular pieces of

page_text: steel with cutting edges where they meet the punches; they are clamped to the
bases e by screws n. The screw passes through the die and enters a tapped hole
in the base.
The hole in the die is elongated so that the die can be set forward or backward
upon the base as may be required. In the cases of the dies me and m² however this
adjustment is not required.
The punching rams at their lower ends receive the punches and these are lettered
n³, n², n³, n', no, no, n², and n³. Shoulders are formed upon the rams for the punches
to abut upon and each die is secured to the ram by a screw o passing through it
horizontally and entering a tapped hole in the side of the ram. In the punches n¹, n³,
n³, n the holes for the screws are elongated to admit of the punch being set forward
or back upon the ram but in the other punches this adjustment is not required.
The cardboard or material to be made into a box is first cut into rectangular pieces
of suitable size and it is scored or cut half through along the lines on which it is
required to fold. The cardboard or material thus prepared is laid on to the machine
by hand between the punches and the dies by the aid of the gauges p p against which
the side and the back edges of the sheet rest. The sheet thus placed is supported
upon the dies m¹ to m³ and where the box to be made is of large size other pieces may
be fixed on the bases e in front of the dies to aid in supporting the sheet.
When the punches descend all the cuts are simultaneously made. The corner
marked 1 in Figure 1 is cut out by the punch n¹ operating in conjunction with
sharpened edges upon the dies m' and m³. The hole marked 2 in Figure 1 is cut
out by the die m² and the punch n². The hole marked 3 in Figure 1 is cut out by
the die m³ and punch n³. The slit marked 4 in Figure 1 is cut out by the punch n
operating in conjunction with sharpened edges upon the dies m³ and "m'. All these
cuts can be produced nearer to the front or nearer to the back as required by.
shifting the dies and punches upon the bases and punching heads.
The slit 5 in Figure 1 is produced by the punch n operating in conjunction with
sharpened edges on the dies m³ and me. The die m is adjustable to vary the length
of the slit but the punch n is not in itself adjustable, it is changed for a longer or
a shorter ono when alteration in the length of the slit is required. The form of
this punch is such that it is very simply made and there is no inconvenience in
having occasionally to change it. The tongue 6 in Figure 1 is produced by the
die m and the punch n these are always in the same position upon the punching
head. The slit 7 and the tongue 8 are similarly produced by dies m² and m³ and
punches and n³. The punch n' is changed when a flap of another length has to
be produced.
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 :-
