Improvements in the Manufacture of Paper and Cardboard Boxes
and in the Machinery employed therein.
I, WILLIAM HARVEY, of 9 Grosvenor Street, Piccadilly, Manchester, in the County
of Lancaster, Paper Merchant, do hereby declare the nature of this invention to be as.
follows:-
In the manufacture of paper and cardboard boxes it is now customary to employ
two or more machines to cut and score the blanks from which the boxes are to be.
made.
In applying my improvements to a machine for making boxes or lids continuously
from cardboard cut to the required width, or cut by any ordinary mechanism attached
to the box machine I secure the cornering knives or dies, the scoring lips and a cutting
off knife or shear to a movable frame which works in combination with a suitable bed
provided with cutting and scoring surfaces. The cardboard is fed under the cutting
and scoring mechanism and remains stationary while the movable frame is brought
down upon it to corner and score the board transversely, when this has been done.
the frame is raised and the board fed forward the required distance when the frame is
brought down again, cutting, scoring and detaching the lid previously partly finished,
and finishing the first end of the next lid and so on. It will be understood that in
this arrangement the lids may be made any length without altering the machine.but
the rims will be of uniform depth and for any different depth of rim the cornering
knife with its counterpart on the bed would need to be changed and the scoring lips
readjusted.
It is obvious that the machine could be made to corner and score several lids or
boxes at each operation of the movable frame the longitudinal cutting discs being
arranged to suit.
In applying my invention to the manufacture of odd sizes of boxes and lids 1
employ a suitably sized table prepared with adjustable gauges, on this table are
mounted knives or dies for cutting out corners, also grooved or other adjustable
scoring surfaces, and shear or cutting edges used for trimming or squaring the boards...
Attached to the machine are brackets for supporting a movable frame to which are
secured cornering dies or a cutting surface where cornering knives are secured to the
bed, and scoring lips in addition to transverse cutting knives or shears.
In operation I propose to take two pieces of board say one for a lid and the other
for a box; these boards are placed in position on the table so that when the movable
frame is brought down on to the table, one edge of each board is cut off or squared,
a corner cut out and one edge scored simultaneously; when this has been done the
boards are moved round on the table until each side in turn has been trimmed,
cornered and squared.

Improvements in the Manufacture of Paper and Cardboard Boxes
and in the Machinery employed therein.
I, WILLIAM HARVEY, of 9 Grosvenor Street, Piccadilly Manchester, in the County
of Lancaster, Paper Merchant, 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 :-
In the manufacture of paper and cardboard boxes it is now customary to employ
two or more machines to cut and score the blanks from which the boxes are to be
made, and the chief object of my present improvements is to enable these operations
to be carried out on one machine.
And in order that my invention may be fully understood and readily carried into
effect I will describe the accompanying sheet of drawings reference being had to the
figures and letters marked thereon.
Figure 1 is a front elevation Fig. 2 an end elevation and Fig. 3 a plan of my
improved machine for making boxes or lids of odd sizes from paper cardboard or
similar material and Fig. 4 is an enlarged section taken on the line A B Fig. 1.
In this machine I secure the cornering knives or dies b, the scoring lips c and a
cutting off knife or shear d to a movable frame e which works in combination with
a suitable bed or table f provided with adjustable gauges a for holding and regulating
the position of the cardboard or other material. The adjustable gauges a a are of
novel construction, those marked a having a separate sliding extension a" which
for large work can be dispensed with. It is obvious that by varying the relative
positions of the gauges a¹ and all or a that any sized pieces of material can be
accurately guided beneath the cornering scoring and cutting mechanism. The cutting
off knife d is supported in a knife carrier d' to which is secured a screwed stud dii
which is adjustable by means of a handwheel g threaded to fit on the stud di and
prevented from moving longitudinally by a plate e¹ secured to the movable frame e.
The movable frame e with its appurtenances is actuated in the ordinary way by
means of eccentrics on the shaft h which is driven by gearing as shown from the main
shaft i.
The paper or cardboard is fed under the cutting and scoring mechanism and
remains stationary while the movable frame e is brought down upon it by the eccentrics
to corner and score the material.
In operation I propose to take two pieces of material say one for a lid and the
other for a box, so that when the movable frame e is brought down on to the table f
as described one edge of each piece is cut off or squared, a corner cut out and one
edge scored simultaneously, and when this has been done the pieces are moved round
on the table until each side has been trimmed, cornered and squared in turn.
It is obvious that the machine could be made to completely corner and cut
several lids or boxes at each downward stroke of the movable frame by simply
re-arranging the cutting and scoring mechanism.
In applying my improvements to a machine for making boxes or lids continuously
from a web or roll of material I dispense with the gauges a, and furnish the machine
with ordinary rotary cutters for cutting the material to the required width and
with the cutting off knife or shear d as before described. In this case double
cornering knives would be employed so as to cut off the corners from two edges
simultaneously.
The web of material is fed into the machine under the cutting and scoring
mechanism by which it is cornered scored and cut and after the movable frame e has
been raised the material is fed forward the required distance the frame e again
brought down thereby cornering scoring and detaching the lid or box previously
partly finished and finishing the first end of the next lid or box and so on.
It will be understood that in this arrangement the lids may be made any length

page_text: without altering the machine but the rims will be of uniform depth and for any
different depth of rim the cornering knife would have to be changed and the scoring
lips re-adjusted.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
1 claim is :-
1. The combination with a bed or table which supports the cardboard or other
material for the blanks, of a movable frame furnished with a fixed cornering knife
or knives, a fixed scoring lip or lips, and an adjustable cutting off knife or knives
whereby blanks for lids or boxes can be cornered scored and cut at one operation and
in one machine.
2. The arrangement use and application of adjustable gauges substantially as and
for the purposes herein described with reference to the drawings.
3. The combination and general arrangement of parts embodying my improvements
in machines for manufacturing paper and cardboard boxes, substantially as herein
shown and described.
