PROVISIONAL SPECIFICATION.
Improved Apparatus for Cutting Shavings for Fire-lighters and the
like.
I, OLOF PETTER MAGNUSSON, of Ostersund, Sweden, Merchant, do hereby declare
the nature of this invention to be as follows:-
This invention relates to an apparatus for cutting shavings in the form of
spitals for fine-lighters and the like This can not be properly done with the
planing machines hitherto used, because the shavings are rolled too hard and
are soon broken, so that it depends too much upon chance to get shavings of
such shape as to be suitable for the intended purpose When using common
planers for directly cutting out spual shaped shavings for fire-lighters, it is
therefore necessary to throw away at least half of the shavings Said incon-
venience is removed by this invention according to which the shavings are rolled
in the shape of a loose spiral with a certain uniform distance between the turns
or layers. This invention consists in so arranging the apparatus that the end
of the rolling iron at the beginning of the stroke of the machine in a given
direction is located just behind the cutting edge of the cutting steel, and during
the stroke moves somewhat slower than the latter so that the end of the rolling
11 on automatically recedes or moves from the cutting edge, thus causing the
shaving to acquire a uniform and continuous curvature
In the accompanying drawing is shown a suitable apparatus for carrying out
this invention
Figs 1 and
show the machine in two projections at right angles to each
other (Fig 2 partly in section)
Figs 3 and 4 show the cutting steel with the rolling iron at the beginning
and the end of a stroke of the machine (from the right to the left hand side)
The machine consist essentially of a reciprocating slide 1, in which the cutting
steels 2 and the rolling irons 3 are placed As shown in Fig. 2 the cutting
steels are inclined in opposite directions so that during the reciprocating motion
of the slide the machine will always be at work. The slide is moved by means
of a connecting rod 5 attached to the clank wheel 4 or in any other suitable
manner
To the said slide is attached a plate 6 or the like, to which two pans of rocking
arms 7 are pivotally connected, said arms being put in oscillating motion by
means of an eccentric connecting rod 8 The two pairs of rocking arms are
connected to each other and to the eccentric connecting rod by means of rods 9
which run in guides 10 The rocking arms are, preferably at their middle part,
provided with oblong apertures for bolts 12 fastened to the links 11
are connected by means of bolts with the rolling irons The latter are pressed
by springs 13 against the cutting steels
Said links
The crank pin of the connecting rod 8 is located somewhat nearer to the centre
of the crank wheel than the crank pin of the connecting rod 5. The latter
moves along the dotted circle 14 (Fig 1), while the former moves along the

page_text: dotted circle 15 During the rotation of the crank wheel the ends of the rocking
aims 7 will, therefore, move a shorter distance than the ends attached to the
slide, the locking aims thus being made to oscillate and move the rolling nons
in relation to the cutting steels It will be seen that the rolling nons alternately
approach to and recede from the edges of the cutting steels, in such a manner
that the lower end of the rolling iron 18 near the edge of the cutting on (see
Fig 3) when the spiral commences to be formed, and recedes while the spiral 18
being formed.
It is obvious that the means for reciprocating the rolling irons relative to the
cutting steels may be varied in several ways, as long as they are suitable for
causing the rolling nons to move from the cutting edge of the cutting on during
the formation of the wood spirali,

COMPLETE SPECIFICATION
Improved Apparatus for Outting Shavings for Fire-lighters and the
like.
I, OLOF PETTER MAGNUSSON, of Östersund, Sweden, 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.-
This invention relates to an apparatus for cutting shavings in the form of
apuals to fie-lighters and the like This can not be propeily done with the
planing machines hitherto used, because the shavings are rolled too hard and
are soon broken, so that it depends too much upon chance to get shavings of
such shape as to be suitable for the intended purpose When using common
planers for directly cutting out spiral shaped shavings for fue-lighters, it is
therefore necessary to throw away at least half of the shavings Said incon-
venience is removed by this invention according to which the shavings are rolled
in the shape of a loose spal with a certain uniform distance between the tuins
or laveis. This invention consists in so alanging the apparatus that the end
of the rolling on at the beginning of the cutting stroke of the machine 18
1ocated just behind the cutting edge of the cutting steel, and during the stroke
moves somewhat slower than the latter so that the end of the rolling iron
automatically recedes or moves from the cutting edge, thus causing the shaving
to acquie a uniform and continuous curvature
In the diawing left with the Provisional Specification 16 shown a suitable
apparatus for carrying out this invention
Figs 1 and 2 show the machine in two projections at right angles to each
other (Fig 2 partly in section)
Figs 3 and 4 show the cutting steel with the rolling iron at the beginning
and the end of the cutting part of a stroke of the machine (from the night to the
left hand side)
The machine consists essentially of a reciprocating slide 1, in which the cutting
steels 2 and the rolling irons 3 are placed As shown in Fig. 2 the cutting
steels are inclined in opposite directions so that during the reciprocating motion
of the slide the machine will always be at work. The slide 18 moved by means
of a connecting rod 5 attached to the crank wheel 4 or in any other suitable
manner
To the said slide is attached a plate 6 or the like, to which two pairs of rocking

page_text: arms are pivotally connected, said arms being put in oscillating motion by
means of an eccentric connecting 1od 8 The two pans of rocking aims are
connected to each other and to the eccentric connecting 1od by means of 10ds 9
which run in guides 10 The 1ocking aims are, preferably at then muddle part,
provided with oblong apertures for bolts 12 fastened to the links 11 Said links
are connected by means of bolts with the rolling mons The latter are pressed
by springs 13 against the cutting steels
The crank pin of the connecting 1od 8 18 located somewhat nearer to the centie
of the crank wheel than the crank pin of the connecting rod 5. The latter
moves along the dotted circle 14 (Fig 1), while the former moves along the
dotted circle 15 During the rotation of the clank wheel the ends of the rocking
aims 7 will, theirfoie, move a shorter distance than the ends attached to the
slide, the rocking aims thus being made to oscillate and move the rolling ons
in relation to the cutting steels It will be seen that the rolling nons alternately
approach and recede from the edges of the cutting steels, in such a manner
that the lower end of the rolling iron is near the edge of the cutting on (see
Fig 3) when the spiral commences to be folmed, and recedes while the spiral is
being formed
It is obvious that the means for reciprocating the rolling ons relatively to the
cutting steels may be varied in several ways, as long as they are suitable for
causing the rolling nons to move from the cutting edge of the cutting iron during
the formation of the wood spial
Having now particularly described and ascertained the nature of this said
invention, and in what manner the same is to be performed, I declare that what
I claim 18.
-
1 In a machine for cutting shavings for firelighters and the like, a mechanism
connected to the rolling irons so as to give the latter a reciprocating motion in
elation to the cutting steels, in such a manner that the rolling ons at the
beginning of the cutting part of the stroke are located just behind the edges of
the cutting steels, from which edges the rolling irons continually recede during
the cutting part of the stroke of the machine and to which they approach during
the return part of the stroke, substantially as and for the purpose set forth
2 In an apparatus of the class described, the combination of 1ocking arms
pivoted to the slide holding the cutting steels, 1olling irons on said cutting steels
pivotally connected to said rocking arms, and a connecting rod connected to said
1ocking aims and a crank the excentricity of said crank being smaller than that
of the crank driving the said slide, substantially as and for the purpose set forth.
3 The combination and arrangement of parts constituting an apparatus fo.
cutting shavings for firelighters and the like, substantially as described in the
specification and illustrated by the drawings
