Apparatus for Scoring Paste, Straw, Card, and like Boards for
Boxes and Cases.
I HENRY GARDNER of 166 Fleet Street, London, Patent Agent, do hereby declare
the nature of this invention, to be as follows:-
This invention relates to certain detail construction or arrangement of apparatus
described in the specifications of Letters Patents Nos. 5894 and 12,477 of the year
1886. In the specifications of those Letters Patents, the circular cutters are con-
nected to distinct holders which are adjustable in V or other grooves of a beam so as
to suit the angle at which said circular cutters having a chamfered face on both sides
can be set and also to suit their distance apart to accomodate them to the distance the
incisions have to be made.
A third frame is described as adjustable in a groove in back of the beam and carries
a chisel, plane iron or gouge tool for removing the material that is between the two
incisions, the cutting edge or face of the chisel, plane iron, or gouge being between
the two circular cutters and directly behind where they penetrate the board, so as to
cut the strip out simultaneously with the action of the circular cutters, thereby
forming a groove or scoring in the board on what is to be the inside of the box.
This adjustment requires great attention on the part of the operator to set both the
circular cutters, to corresponding angles so that the incisions are properly inade.
Now, the object of the present invention is to obviate this inconvenience and this is
effected by coupling the frames of the two circular cutters by a link or saddle pieco
at their upper ends and in fitting to the lower part of the two frames a double action
screw pin, the threaded ends of which engage in studs fitted in recesses at the back
and in which said studs have a circular motion for adjustment as the lower parts of
the two frames are thrown farther apart by turning the screw pin.
One of the frames has a leg piece in which the chisel, plane iron, or gouge is set
centrally between the two circular cutters by a screw bolt and pinch nut.
By this arrangement the back frame for carrying the chisel, plane iron, or gouge
tool, is dispensed with and the appliance for forming the groove or scoring is more
compact than heretofore.

Apparatus for Scoring Paste, Straw, Card, and like Boards for
Boxes and Cases.
I HENRY GARDNER of 166 Fleet Street, London, Patent Agent, do hereby declare
the nature of this invention which has been communicated to me from abroad by Jean
Scherbel and Teodor 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 :-
This invention relates to certain detail construction or arrangement of apparatus
described in the specifications of Letters Patents Nos. 5894 and 12,477 of the year
1886; in the specifications of those Letters Patents the circular cutters are connected
to distinct holders, which are adjustable in V or other grooves of a beam so as to suit
the angle at which said circular cutters, having a chamfered face on both sides can be
set and also to suit their distance apart to accomodate them to the distance the
incisions have to be made. A third frame is described as adjustable in a groove in
back of a beam and carries a chisel, plane-iron, or gouge tool for removing the
material that is between the two incisions, the cutting edge or face of the chisel,
plane-iron, or gonge being between the two circular cutters and directly behind
where they penetrate the board so as to cut the strip out simultaneously with the
action of the circular cutters thereby forming a groove or scoring in the board on
what is to be the inside of the box. This adjustment requires great attention on the
part of the operator to set both the circular cutters to the necessary angles, so that the
incisions are properly made.
Now the object of the present invention is to obviate this inconvenience and this is
effected by coupling the frames B, B, of the circular cutters A, A, by'a link or saddle
piece R at their upper ends, as seen in Figure 1 of the annexed drawings, and in
fitting to the lower part of the two frames B, B, a double action screw pin S, the
threaded ends S, S', of which engage in studs T, T, fitted to swivel in recesses U, U,
(see Figure 2) in the frames B, B, and in which recesses U, U, said studs T, T, have
a swivel or circular motion for adjustment as the lower parts of the two frames B, B,
are thrown further apart by turning the screw pin S such as when a thicker plane-iron
has to be fitted in for making a wider groove.
One of the frames has a leg piece (see Figure 3) in which the chisel, plane-iron
or gouge J is set centrally between the two circular cutters A, A, by a clip screw
bolt W, and pinch nut X (see Figures 3 and 4). E is the roller which carries the
board through the apparatus for the groove to be cut.
By this arrangement the separate frame for carrying the chisel, plane-iron, or
gouge tool is dispensed with and the appliance for forming the groove or scoring is
more compact than heretofore.
It is evident on reference to the drawings (Figure 1) that the two frames B, B,
when the nuts I, I, are loosened, can be set at any desired angle so that one circular

page_text: cutter A may cut vertically and the other circular knife cut at an angle, the swivelled
studs T, T, adjusting themselves in the recess U, U, to suit, the hole Z through which
the screw passes being enlarged outwardly for this
purpose.
Having now particularly described and ascertained the nature of this invention and
in what manner the same is to be performed I declare that what I claim is
1 In a paper board scoring machine, linking or coupling two frames B, B, and
combining with such frames a double action screw pin S, and swivel studs T, T, for
adjusting and determining the distances the two knives A, A, shall be set apart, as.
described.
2 In a paper board scoring machine, affixing the plane-iron or gonge tool J to a
leg or projection Q of the frame B which carries one circular cutter A as and for the
purpose described and substantially as shown in the annexed drawings.
