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 :-
The object of this invention is to plane out by a planing tool or chisel that
portion of a paste, straw, card or like board that is between slits formed by
circular or other cutters employed for the preparation of such boards for boxes and
cases, said planing being effected simultaneously with the other cutters or at
distinct times and in one or the same machine or in different machines. The paste,
straw, card or other like board may be in the rough, be rolled, glazed printed or
otherwise surfaced or the said board may be covered by say a paper or other cover
or liner on the side on which the cutting and ploughing is effected or on the
opposite side or on both sides by the same or by different coloured papers so that
said board when folded in the crease or tissure has a rounded edge perfectly
smooth and clean, the box or half box or the lid as the case may be without
requiring edge paper or edge coverings or binder strips as is usual with such boxes
as at present made.
I employ circular knives chamfered on both sides to a cutting edge and fitted
loosely in frames which are adjustable both as to depth which said knives shall.
penetrate the board and as to angle at which such cut shall be made and also as to
the distance apart of such cutting. I also employ with the said circular knives
and either in the same machine or in a different machine a planing tool or chisel
with a cutting edge or face corresponding in width to that of the board at the
bottom of and between the two slits made by the circular cutters to slice that
portion from the board, thus leaving say two angled side walls looking in opposite
directions with a flat or nearly flat base between them but having sufficient
thickness of material that when the folding takes place the two angle faces abut

splitting or tearing the same, the rounded portion being perfectly smooth and in a
finished state.
The plane iron or chisel is set in an adjustable frame and has its cutting edge or
point formed from two inclines one of which is in contact with the base of the
scored groove to smooth the surface and also to prevent the board bending or
buckling in its transit through the machine.
I prefer that the chisel or planing tooling acts simultaneously with that of the
angle cutting the face or edge of the plane being directly behind where the circular
cutters have made their incisions.

The paste or other board is carried through the machine by a roller under the
pressure of the circular cutters, but other pressure rollers may be employed to keep
the board flat during the cutting operation.
In front of the roller is a slab or table provided with a guide which can be set
to ensure the proper position of the scoring groove at the same time it acts as a
straight edge. When large size boards are being score grooved two of said guides
can be used.

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 and ascertained in and by the following
statement:
The object of this invention, is to plane out by a planing tool or chisel that
portion of a paste, straw, card, or like board that is between slits formed by
circular or other cutters employed for the preparation of such boards for boxes
and cases, said planing being effected simultaneously with the other cutters or at
distinct times and in one or the same machine or in different machines. The paste,
straw, card, or other like board may be in the rough, be rolled, glazed, printed, or
otherwise surfaced or the said board may be covered by, say, a paper or other
cover or liner on the side on which the cutting and ploughing is effected or on the
opposite side or on both sides by the same or by different coloured papers so that
said board when folded in the crease or fissure has a perfectly rounded edge smooth
and clean, the box or half box, or the lid as the case may be without requiring
edge paper or edge coverings or binder strips as is usual with such boxes as at
present made.
This invention is based upon my previous Application for Patent No. 5894
dated 30 April 1886, in the Specification of that Patent I describe the employment
of circular cutters with or without a plough knife, plane, or gouge and according
to the present invention I always employ a planing tool for completing the scoring
whether the circular cutters be used at the same time as the planing tool or at
different times, the circular cutters being so set as to make the incisions and the
planing tool to remove the strip from between.
For the purpose of this invention, I employ circular knives A. A as shown in the
annexed drawings front and side view respectively chamfered on both sides to a
cutting edge and fitted loosely in frames B which are adjustable as to depth by the
screw pin F, which said knives A shall penetrate the board, and as to angle by
bolt G and pinch nut I at which such cut shall be made and also as to the distance
apart of such cutting, the holders B being carried by screw bolts G affixable in a
V or other groove of a beam C and by pinch nuts I.
I also employ with the said circular knives A and either in the same machine or
in a different machine, but preferably in the same machine a planing tool or
chisel J the fore part of which is between the two circular cutters A with a
cutting edge or face, hollow or not, and in position to cut simultaneously with said
circular cutters. The planing tool or chisel J corresponds in width to that of the
board D at the bottom of and between the two slits made by the circular cutters to
slice that portion P from the board D thus leaving two angled side walls looking
in opposite directions with a flat or nearly flat base between them but having
sufficient thickness of material that when the folding takes place the two angle

page_text: faces abut against each other and leave the outside edge of rounded form without
cracking, splitting, or tearing the same, the rounded portion being perfectly smooth
and in a finished state.
The plane, iron or chisel J is set in an adjustable frame K and has its cutting
edge or point formed from two inclines one of which is in contact with the base of
the scored groove.
The frame K is adjustable as to the depth of its cutting by the
screw pin Land can be set to any part of the beam and fixed by the bolt N and
. pinch nut M.
The paste or other board is carried through the machine by a roller E under the
pressure of the circular cutters A, but other pressure rollers may be employed to
keep the board flat during the cutting operation.
In front of the roller E is a slab or table R provided with a guide which can be
set to ensure the proper position of the scoring groove at the same time it acts as
a straight edge. When large size boards are being score-grooved two of said guides
can be used.
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
The employment of a plane or chisel faced tool for removing a strip by a cutting
operation from between two incisions made by circular cutters in paste, straw,
mill, or other like board for scoring the same for the manufacture of paper, card-
board, and like boxes as herein before described and substantially as shown in the
annexed drawings.
