A Machine for Nicking or Scoring Leather and the like.
We, FRANK ERNEST WHEELER, of 14, Lancaster Road, Leicester, Engineer, and
PEARSON AND BENNION, LIMITED, of Union Works, Leicester, Engineers, do hereby
declare the nature of this invention to be as follows:-
Our invention relates to machines for cutting, nicking or scoring leather, card-
board and the like and consists chiefly of a knife, feed-roll, presser, guides, and
means of actuating same.
The knife is actuated by a crank, eccentric, cam or other suitable means and may
have a straight or curved motion and the path of the cutting edge may be either
tangential with the surface of the feed-roll or radial with its axis or in any
position between these extremes and it may be adjustable; the depth to which
the knife penetrates the material is also adjustable.
or continuous feeding
The feed-roll may be actuated by any intermittent
mechanism and the distance the material is fed for each stroke of the knife may be
adjustable.
The material being operated upon is pressed in contact with the feed-roll by
springs or weights acting on a plate, roller or lever.
Guides are provided by means of which the material is accurately guided
through the machine.

A Machine for Nicking or Scoring Leather and the like.
We, FRANK ERNEST WHEELER, of 14, Lancaster Road, Leicester, Engineer, and
PEARSON AND BENNION, LIMITED, of Union Works, Leicester, 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 relates to machines for nicking, scoring or cutting leather, card-
board and the like, and consists chiefly of a knife, feed-roll, presser, and guides,

page_text: According to our invention the nicking or scoring is effected by a knife having
a straight or curved motion imparted to it by an eccentric, crank, or other suitable
means, and the path of the cutting edge may be either tangential with the surface
of the feed-roll or radial with its axis or in any position between these extremes.
The leather or the like to be nicked or scored, while passing over the feed-roll is
submitted to the action of the knife, the depth to which the latter penetrates the
material being adjustable. The invention will be understood by reference to the
drawings accompanying this specification, in which Fig. 1, shows an elevation
and Fig. 2, a plan of a machine constructed in accordance with one form of our
invention. Fig. 3 is a central vertical section and Fig. 4, a sectional plan taken
on the line Z, Z, of Fig. 3. Like letters of reference refer to like parts throughout
the several figures.
The frame A has sides A¹. A shaft B carried in the said sides A' has fixed
thereon by the screw C₁ an arm C which carries at its further end the knife D
held by the screws D₁ which passing through slots in the said knife allow of it
being adjusted in height in respect to the said arm and kept in position by the
set screws D³. To impart the necessary movement to the said knife D the arm C
carrying the said knite is connected by a pin C to the lower end of an eccentric
rod E, formed with straps in the well-known manner to surround the eccentric E¹
which is fixed in any desired way on the driving shaft F, the latter being carried
in the sides A¹ of the frame A. It is obvious however, that instead of the
eccentric E the shaft F may be cranked to effect the same purpose.
The said shaft F is revolved by hand or by a band, belt or strap (not shown in
the drawings) passing round the grooved pulley or equivalent F₁ from any con-
venient source of power. It will be readily understood that the knife D instead
of being mounted on the arm C, as shown in the drawing, could be effectively
arranged to move in slides which could be mounted upon quadrants and the latter
so pivotted to the sides A that any desired angle or pitch could be given to the
knife. The feed-roll G which is preferably milled on its circumference may be
formed solid with its journals G¹ or fixed on a shaft carried in bearings A2 in the
said frame A. Motion is imparted to the said feed-roll G by the slotted lever H
fixed on the shaft B by the screw H₁ engaged by the bolt B3 passing from the
extension H2, on the arm J' of the boss J mounted on the screw J, which, passing
into the shaft or journal G¹ secures a plate J hereinafter mentioned in position.
Mounted on the square end G2 or otherwise fixed to the shaft or journal G¹ and
revolving therewith is a disc K having a flange K¹ which is gripped and tensioned
by the dogs L. The boss J (see Fig. 1) has depressions or flats J* cut opposite
each other; the corners serving as the pivot upon which the dogs L may turn.
The said dogs L are recessed at L¹ to engage the flange K¹ of the disc K by means
of the springs K2 whose ends are connected to the arms and said dogs L, by
which means the feed-roll is tensioned or controlled. The said dogs L are kept in
proper relation to the face of the flange K of the disc K by means of the plate J
before mentioned. The guides M are adjustable in relation to each other for
varying widths of material by means of the right and left screw N whose ends N¹
are mounted in the lugs O secured to the frame A as shown in Figure 3, or the
said lugs may be cast on the frame and a sleeve driven in one lug after the said
screw is in position. The material when being operated upon is pressed, in contact
with the feed-roll G by the presser P', the sides P¹ of which are pivotted on the
spindle Q carried in the sides of the frame. The said presser P has a slot 12 formed
therein to allow of the operation of the knife. Pressure is preferably put upon
the extensions P³ on the sides of the presser P by means of the springs R surround-
ing the spindles S, though it is obvious that pressure may be applied to the
presser in several ways other than as described. A stud T is fixed in one side
of the frame upon which the thumb of the operator may be placed when the
presser requires to be raised by means of its handle P. Although the machine
as described embodies the most satisfactory constructional arrangement it is clear
that various modifications of several features may be effected within the scope of

page_text: our invention, i.e. the machine may be made of any convenient width and
provided with more than one pair of guides M and one long knife D or a series of
short knives and also a series of pressers, by which means several pieces of material
can be operated upon at the same time. Also a ratchet and pawl form of feed
may be used, operated from any convenient moving part of the machine, or a
continuous movement can be given to the feed-roll & by bevel wheels and worm
gear. It will also be understood that the knife is not limited to cutting square
across the material; it may also cut at any angle, and the cutting edge may be
straight, concave, or convex.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is:-
1. In machinery for nicking or scoring leather, cardboard or the like, the
employment of a knife operated in the manner substantially as described.
2. in machinery for nicking or scoring leather, cardboard or the like the con-
bination with the feed-roll of a knife and means for adjusting said knife to increase
or decrease the depth of the nick or score substantially as described.
3. In machinery for nicking or scoring leather, cardboard or the like the
combination of a feed-roll, horizontally adjustable guide plates, a knife adjustable
for varying depths of nick or score and means for actuating the said knife, sub.
stantially as described.
4. In machinery for nicking or scoring leather, cardboard or the like the com-
bination of a knife and means for actuating same, a feed-roll and means for
tensioning or controlling the said feed-roll substantially as described.
5. In machinery for nicking or scoring leather, cardboard or the like, a knife
and means for adjusting and actuating same, arranged and operating substantially
in the manner described and illustrated in the accompanying drawing.
6. The improved machine for nicking or scoring leather, cardboard, or the
like described and illustrated in the accompanying drawing.
