Improved Machine for Cutting or Tearing up Rags, Ropes and the like.
I, PETER JENSEN, of 77, Chancery Lane, London, Chartered Patent Agent, do
hereby declare the nature of this invention, a communication to me from abroad
by Hans Albert, of Kronstadt, in Transylvania, Hungary, Merchant, to be as
follows:-
This invention refers to a machine for tearing up rags, rope ends and similar
articles of any size for the purposes of paper and millboard manufacture, or for
spinning, weaving and rope making, and without the application of water, so that
the greatest possible uniformity and sufficient length of fibres are obtained while
the time required as compared with that by the ordinary rag engine is reduced
to a minimum.
The yield is by this construction many times larger than by the machines
usually employed in this branch.
The cutting apparatus forming an essential part of the invention consists of a
chambered nave or boss fixed on the spindle and helically grooved on the outside,
for receiving steel segments set close to each other and fixed to each other. The
outer peripheral helical edge of the segments is formed with teeth of the form of
those of a circular saw. This helical cutting blade at each end terminates at a
flange on the boss. The parts may be fixed by means of screw bolts. The flanges
are somewhat larger in diameter than the helical cutter so that the material to be
torn up may not escape laterally and also for keeping the dust from flying about
laterally. Between the windings of the cutter are provided wood stays to prevent
the cutter segments from being bent.
The length and shape of the teeth may vary and according to the length of
fibre required.
Instead of the helical cutter made of segments I may use a number of toothed
discs placed straight or slanting.
The material placed evenly on a travelling feeding table or endless apron
which feeds it in between two grooved iron rollers the upper one of which runs in
bearings that can move vertically and are kept down by weights. The material
thence passes into a throat or mouthpiece the upper part of which is also loaded
with weights and which can open more or less according to the thickness of the
material and the weights. The rollers and the mouthpiece are connected so that
the rear part of the latter is lowered when the upper roller is lowered while at
the same time the front side is lowered and squeezes together the material. It is
necessary for the production of material of uniform quality that the rags or other
material should be compressed as it comes in contact with the cutter edge.
guard is provided at the cutter and the motion of the cutter is regulated by a fly-
wheel.

The fibres loosened in each direction by the cutting through of the fabric are
disintegrated by the centrifugal force of the quickly rotating cutter and pass

Improved Machine for Cutting or Tearing up Rags, Ropes and the like.
I, PETER JENSEN, of 77, Chancery Lane, London, Chartered Patent Agent, do
hereby declare the nature of this invention, a communication to me from abroad
by Hans Albert, of Kronstadt, in Transylvania, Hungary, Merchant, and in what
manner the same is to be performed to be particularly described and ascertained
in and by the following statement:-
-
This invention refers to a machine for tearing up rags, rope ends and similar
articles of any size for the purpose of paper and millboard manufacture or for
spinning, weaving and rope making, and without the application of water so that
the greatest possible uniformity and sufficient length of fibres are obtained while
the time required as compared with that by the ordinary rag engine is reduced
to a minimum. The yield is by this construction many times larger than by the
machines usually employed in this branch.
The new machine is shown in the part sectional side view Fig. 1; Figs. 2 and 3
are detail views of the cutting apparatus forming the essential part of the inven-
tion. It consists of a chambered nave or boss b fixed on the spindle a and helically
grooved on the outside for receiving steel segments c set close to each other and
fixed to each other. The outer peripheral helical edge of the segments is formed
with teeth of the form of those of a circular saw. This helical cutting blade at
each end terminates at a flange on the boss. The parts may be united in the
known manner by means of screw bolts. The flanges & are somewhat larger in
diameter than the helical cutter so that the material to be torn up may not escape
laterally and also for keeping the dust from flying about laterally. Between the
windings of the cutter and against the flange d are provided wood stays to prevent
the cutter segments from being bent.
The length and shape of the teeth may vary and according to the length of fibre
required. Instead of the helical cutter made of segments I may use a number of
toothed discs placed straight or slanting.
The material is placed evenly on a travelling feeding table or endless apron e
which feeds it in between two grooved iron rollers f and f¹: the upper one f¹ runs
in bearings that can move vertically and are kept down by weights. The material
thence passes into a throat or mouthpiece g, g¹, the upper part of which is indepen-
dently loaded with weights and can rise and fall according to the thickness of the
material and the weighting of same, being pivotted to the spindle of the roller f¹,
by means of lugs passing over the ends of the spindle, or in any other convenient
manner. The roller and the mouthpiece g¹ being thus connected rise and fall
simultaneously. It is necessary for the production of material of uniform quality
that the rags or other material should be compressed as it comes in contact with
the cutter edge. A guard is provided at the cutter and the motion of the cutter
is regulated by a flywheel.
The fibres loosened in each direction by the cutting through of the fabric are
disintegrated by the centrifugal force of the quickly rotating cutter and pass

page_text: down an inclined plane in the machine enclosing box from whence they are
delivered into a receptacle.
This machine ensures certain and quick work, yields an excellent product and
can be easily and conveniently repaired.
Having now particularly described and ascertained the nature of the said in-
vention and in what manner the same is to be performed as communicated to me
by my foreign correspondent, I declare that what I claim is:-
1. A machine for cutting or tearing up rags, ropes, or the like characterized by
a helical saw toothed blade which operates upon the material that by means of an
endless apron and weighted grooved feed rollers is fed into a weighted movable
mouthpiece so that the material is cut up evenly and by centrifugal force
disintegrated substantially as set forth.
2. In a machine for cutting or tearing up rags, ropes, or the like a saw toothed
blade made in parts fixed in a boss between flanges in combination with suitable
feeding and squeezing devices for the material to be cut up substantially as set
forth.
3. In a machine for cutting or tearing up rags, ropes or the like the helical saw
toothed blade made of segments c fixed in a boss 6 between flanges & substantially
as set forth.
4. The construction of machine shown on the drawing.
