page_text: I HENRY GARDNER of 166 Fleet Street, City of London, Patent Agent, do hereby
declare the nature of this invention which has been communicated to me from
abroad by :-Jean Scherbel and Theodor Remus both of Dresden, Kingdom of
Saxony, Empire of Germany, Manufacturers, to be as follows:-
In the manufacture of boxes and cases from paste and like boards the practice
in many establishments is, as a preparation for the bending over of the edge, to
make a little fissure or slit in the piece of card on the outside and also a stainped
crease on the inside. Now this invention relates to an apparatus destined to cut
out a two or three sided channel in the surface of paste and like board by adjustable
circular cutters and an adjustable plane or gouge tool if desired these being
supported by a beam and used in combination with a roller or surface on which
the pasteboard travels.
The apparatus consists of a slotted horizontal beam carrying adjustable arms
which carry at their lower ends in forks circular cutters or knives which can be
brought to any desired part of the whole length of the beam and be fixed vertically
or at any desired angle or at any suitable angle to each other.
Between the two forked adjustable circular knife carriers and on the beam a
planing or gouge tool may be arranged also capable of being set at an angle and
adjustable as to position both in height and in the slot of the beam.
Under the axes of the two circular cutters and parallel to the beam is a feed
roller on which the paste board is supported and on which it travels.
The incisions or channels made in the paste board are cut to the depth determined
by the operator and the circular cutters if used alone cut two angled sides only
such as is necessary for thin paste board but for the stiffer or thicker kind of paste
or like board the plane is used in addition to the circular cutters whereby a
groove or channel is made having a flat or comparatively flat bottom surface or
quadrangular grooved slit or incision,

I HENRY GARDNER of 166 Fleet Street, City of London, Patent Agent do
hereby declare the nature of this invention which has been communicated
to me from abroad by Jean Scherbel and Theodor Remus both of Dresden,
Kingdom of Saxony, Empire of Germany, Manufacturers and in what manner the
same is to be performed to be particularly described in and by the following
statement
In the manufacture of boxes and cases from paste boards and like boards the
practice in many establishments is, as a preparation for the bending over of the
edge to make a little fissure or slit in the piece of card on the outside and also a
stamped crease on the inside. Now this invention relates to an apparatus destined
to cut out a two or three sided channel in the surface of card, paste and like board
by adjustable circular cutters and an adjustable plane or gouge tool if desired
these being supported by a beam and used in combination with a roller or surface
on which the pasteboard travels.
The apparatus consists of a slotted or grooved horizontal beam carrying
adjustable arms which carry at their lower ends in forks circular cutters or knives
which can be brought to any desired part of the whole length of the beam and be
fixed vertically or at any desired angle, or at any suitable angle to each other.
Between the two forked adjustable circular knife carriers and on the beam a
plane or a gouge tool may be arranged also capable of being set at an angle and
adjustable as to position both in height and in the slot of the beam.
Under the axes of the two circular cutters and parallel to the beam is a feed
roller on which the paste board is supported and on which it travels.
The incisions or channels made in the pasteboard are cut to the depth determined
by the operator and the circular cutters if used alone cut two angled sides only,
such as is necessary for thin pasteboard, but for the stiffer or thicker kind of card,
paste or like board, the plane is used in addition to the circular cutters whereby
a groove or channel is made having a flat or comparatively flat bottom surface or
quadrangular grooved slit or incision.
The invention will be clearly understood by reference to the annexed drawings
in which at Figure 1 I show in elevation two circular cutters A A carried by
holders B, B, set at such an angle in the beam C that the cutters A form two
incisions meeting at the bottom and form a V groove or channel in the card or
other board D which is passing under them by the roller E due to the pressure
between said roller and the circular cutters. The depth of the incisions in the card
board in which the circular cutters A make their cut is regulated by the screw

page_text: bolts F which bear upon blocks G arranged in V or other shaped grooves H of the
beam C, said holders being fixed in position by the pinch nuts I.
The circular knives A and holders B can be set at any angle by loosening the
pinch nuts and moving the holders farther apart to determine the distance the
incisions should be apart this being mainly determined by the thickness of card
and like board being operated upon.
The circular cutters have an angled face from both sides and when set at an
angle such as is represented at Figure 2, a plough knife, a plane or gouge J is
employed to remove the strip of board that is between the two angle cuts of the
circular knives and thus form a flat or nearly flat base to the channel or groove.
When the plough, plane, or gouge tool J is used, it is set from the back of the
machine in a holder K and adjustable in a slot of the beam C so that the plane
iron or gouge can be set and occupy a position between the two circular cutters as
seen at Figure 3. The holder K is adjustable as to height by its screw bolt L and
can be set as to angle by its pinch nut M acting on the block N and nipping it in
the groove in the back of the beam C.
The lower part of the holder K is curved as seen at Figure 2 so that the strip P
which is removed from the card by the plane iron or gouge J may rise over the
said lower part Q and be kept clear of the appliance as removed from the card
board.
The cardboard is placed upon a table R and is pushed forward for the roller E
and the circular cutters A to grip it, the rotation of the roller carrying it rapidly
through the machine.
The roller E may be driven by gearing S from a treadle T as seen at Figures 4
and 5 which are respectively a back and side elevation of sufficient of the machine
in which the grooving or scoring of paste, card, straw and other like boards can be
effected.
Boards, such as card and paste board, grooved or scored with a V groove in the
manner above set forth and as shown at Figure 6 and bent at right angles as shown
at Figure 7 have a rounded outside edge the sides of the groove formed by the
cutters abutting upon each other as shown, but with boards of great thickness
such as straw boards and the like it is necessary that the channel or groove should
be made wider and for this purpose the circular cutters are set farther apart and
the plane iron or gouge is used for removing the strip from between the two
incisions made by the circular cutters, the groove being of the form shown at
Figure 8 so that the board when folded as at Figure 9 has a rounded edge as in
the previous case, that portion of the board which is left solid at the bottom of the
groove will yield to the bend without cracking the under or outer surface.
This invention enables boards to be completely prepared before grooving that is
to say they may be lined or covered with plain or coloured paper as a lining or
facing and as far as the four edges are concerned they are in a finished state when
folded and do not require binding strips or to be covered with paper or other
material as is usually practised with the present system in making paste board and
like boxes.
In Figure 3 the plane iron or gouge is shown between the circular cutters and
directly behind their point of contact with the roller so that the strip P is removed
simultaneously with the making of the incisions but the strip removing operation
may be effected at a distance from the circular cutters in the same machine or in
a separate machine as desired.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what
I claim is
1. Scoring, grooving or cutting channels with angled sides in pasteboards and
the like by circular cutters A, A, having an inclined face on each side and arranged

page_text: in carriers B B which are adjustable as regards angle and distance apart upon the
beam C with or without an adjustable planing or gouge tool J in combination with
a feed roller E as set forth and substantially as shown in the annexed drawings.
2. The employment of a plane iron or gouge tool to remove the strip from card,
straw or like boards from between where incisions have been made by circular
cutters as described and substantially as shown in the annexed drawings.
