Improvements in and connected with Machines for the Manufacture
of Wood Wool or similar Product.
I, CAESAR HASS, of 261 Burdett Road, Limehouse, London, Manager and
Director, do hereby declare the nature of this invention to be as follows:-
The object of my invention is improvements in and connected with machines for
the manufacture of wood wool or similar product such as wood fibre used for the
manufacture of paper pulp, whereby greater efficiency of action of the machine is
ensured and a larger quantity of material produced.
The main features of my invention are:-
Constructing a continuous row of metal slats, rivetted to a broad band arranged
over pullies, in such a manner that on a straight line each slat will support its
neighbour edgeways and thus in conjunction with the slides form a complete
solid table to give sufficient resistance to the pressure of the knives against the
wood.
Providing a small roller suspended by a hinged frame the piece of wood which
is being worked to rest against such roller which is put as near the working surface
that when the wood is cut down to a residue of about 1 inch, the roller will be
forced up by the wood and the latter be thrown out of the machine automatically.
Providing a knife cleaner placed as close as possible to the place where the wood
is cut. Such knife cleaner consisting of a wheel of wood, or other material softer
than iron and is driven at a far greater speed than the knives but in the same
direction and will thus by coming in contact with the latter clean them from any
chips which might remain thereon.
For the purpose of my invention, I construct a framing and affix therein in
suitable bearings two or more pullies carrying an endless band to which are attached
by rivets or otherwise metal slats, each slat being of greater length than the
width of the endless band and in fairly close proximity to each other around
the belt.
On each slat and preferably at those outside the endless baud I affix by screw
rivets or otherwise steel or hard metal plates, these being of such a degree of
hardness as to withstand for a length of time the friction created when the machine
is in work, and these plates being attached to the slats by screw rivets or similar
appliances can when worn down be easily renewed without destroying the slats.
от
and
Certain slats and plates preferably at equal distances apart, are provided with
holes or slots for containing the knife or knives or scorers used for scoring cutting
the wood under operation, said knives or scorers being adjustable as to depth or
angle of cut by a screw pin which engages with a projection formed on or attached
to the under part of the slat through which the hole is cut.
The metal slats are formed with projecting corners, so that each one is in touch
with its neighbour at those points only when they are in a straight line; thus
they will support each other and by their conjunction with the plates form a
sufficient resistance to the action of the knives when at work and so prevent great
strain upon the machine.
On each side and in line with the upper edge of the pullies I arrange tracks
having bearing surfaces and over which the endless band of slats and plates move,
grooved or other guides being fitted on the under or inner side of the slats for

page_text: engaging the bearing surfaces of the tracks and preventing side motion of the
band thus keeping the knives always in the proper line and position for work.
Adjacent to the hoppers or feed entries of the machine is a hinged rod or rods
carrying a roller or other appliance which rests against the piece of wood under
operation and when the wood is cut down by the knives to about inch in thickness,
or just below the centre line of the roller, the knives acting on the wood meeting
with no resistance force the piece of wood under the roller and along to the end of
the machine and automatically ejects it clear of the machine, a fresh piece of wood
taking its place to be acted upon by the knives following.
I also arrange as near as possible to the place where the wood is cut, a knife
cleaner which consists of a roller or wheel of wood or other material softer than
the knives or cutters, said roller or wheel being arranged on a hinged frame and
by gearing or belting driven to a far greater speed than the knives motion but in
the same direction so that it will by coming in contact with the knives clean them
from any chips or other debris which might remain thereon.
The pulley bearings are so arranged as to be adjustable for taking up any slack
of the endless band.
The machine is fed by hand with pieces of wood of a given size and between
the pullies above the tracks and the operators holding the top piece or pieces of
wood down to give sufficient resistance to the knives which cut the bottom piece
of wood from underneath, or a number of pieces of wood may be arranged one
above the other to create weight to give the necessary resistance. The product is
guided by a shield or shields to the sides and clear of the machine and can be
readily removed by an attendant.
The endless band of slats is driven by pullies or gearing arranged at one side
of the machine and on one of the band pullies axle.
By the improvements herein before set forth, wood wool of any degree of thickness
and width can be produced in a rapid and less costly manner than by machines at
present constructe 1.

Improvements in and connected with Machines for the Manufacture
of Wood Wool or similar Product.
I, CAESAR HASS, of 261 Burdett Road, Limehouse, London, Manager and
Director, 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 :-
The object of my invention is improvements in and connected with machines for
the manufacture of wood wool or similar product such as wood fibre used for the
manufacture of paper pulp, also for manufacturing matches and match splints and
the like, whereby greater efficiency of action of the machine is ensured and a larger
quantity of material produced.
The main features of my invention are:-
Constructing a continuous row of metal slats rivetted to a broad band arranged
over pullies in such a manner that on a straight line each slat will support its
neighbour edgeways and thus in conjunction with the slides form a complete
solid table to give sufficient resistance to the pressure of the knives against the
wood.
Providing a small roller suspended by a frame for each piece of wood which is

page_text: being worked to rest against such roller which is put as near the working surface
that when the piece of wood is cut down to a residue of about half an inch the
roller will be forced up by the wood and the latter be thrown out of the machine
automatically, the roller returning to its working position by a spring.
Providing a knife cleaner placed as close as possible to the part where the wood
is cut, such knife cleaner consisting of a wheel of wood or other material softer than
iron and is driven at a far greater speed than the knives but in the same direction,
and will thus by coming in contact with the latter clean them from any chips which
might remain thereon.
My invention will be clearly understood from the following description, reference
being had to the annexed drawings in which
Figure 1 is a longitudinal sectional view of a machine (through the line a, b, of
Figure 2).
Figure 2 is a plan of the machine.
Figures 3 and 4 are sections looking towards either end section of the machine
through the lines c, d, and e, f, of Figure 1 respectively.
Figure 5 is an edge view on an enlarged scale of a portion of the broad band
having affixed thereto the metal slats and plates and showing a multiple grooving
tool and a plain edged knife in position.
Figure 6 is a plan, also on an enlarged scale, of some of the metal slats and plates
showing the position they occupy one with the other, and with three plates removed
to show the construction of the corners of the metal slats.
Figure 7 is a section on line g, h, of Figure 6 showing the band, metal slats,
plates, and guides combined.
A is a framing to which is affixed in suitable bearings B, pullies C, D, carrying
an endless band E to which are attached by rivets or otherwise metal slats F, F,
each slat being of greater length than the width of the endless band E and arranged
next each other around the band E but with a narrow space between each. On
each slat F and preferably at those parts outside the endless band E, I affix by
screw rivets or otherwise steel or hard metal plates G, these being of such a
degree of hardness as to withstand for a length of time the friction created when
the machine is in work, and these plates G being attached to the slats F by screw
rivets or similar appliances, as at Figure 6, can when worn down be easily renewed
without destroying or interfering with the slats F.
Certain slats Fand plates G preferably at equal distances apart, are provided
with holes or slots H, Figures 5, 6, and 7, for containing the groovers or scorers I
and knives I used for grooving or scoring and cutting the wood under operation,
said groovers or scorers and knives being adjustable as to depth or angle of cut
by a screw pin J which engages with a projecting portion K attached to the under
part of the slat through which the hole H is cut.
or
The groovers or scorers I (which may be of any construction) are arranged
alternately so that the wood under operation is first grooved or scored by the
groovers or scorers to the depth and width required according to the nature of the
product required and in the case of grooving the wood the remaining projecting
parts between the grooves are cut off by the knife following so as to make the wood
flat or comparatively flat on the operative surface ready for the next grooving tool
to act upon it but in the case of simply scoring the wood the width required, the
knife would slice off to the desired depth the whole surface of the wood to
produce the wood wool or other product, or each groover or scorer and knife may
be combined in one article as is well known.
The metal slats F are formed with projecting corners L for each one to be in
touch with its neighbour at those points only when they are in a straight line, thus
they will support each other, and by their conjunction with the plates form a solid
band sufficient to form resistance to the action of the groovers and knives when at
work and so prevent great strain upon the machine. In the event of any of the
slats not touching its neighbour, a simple knock by a hammer at the projecting
corner will force it into contact with its neighbour.

page_text: .
On the under or inner side of the slats F'and outside the edges of the belt E
I affix segments M having an opening lengthwise, somewhat of U shape, and at
about the outside edge of the slats I affix other segments N, these being of flat
shape, but they may have the U shaped opening lengthwise.
These segments are in close proximity to each other end ways and form guides all
round the inner side of the slats, and being angled faced at their ends can partake
of the circular shape of the pullies C, D, when passing around them.
The guides M, N, run upon tracks P, Q, the tracks P being arranged on each
side on an inner framework A¹ of the machine, and the tracks Q upon the outer
framework A of the machine; the working surface of the tracks being in line with
the upper edge of the pullies C, D, so as to form a solid table for the cutting to
be effected on and by the shape of the guide M and track P all side motion of the
band is obviated and consequently the cutters are always in the proper line and
position for working.
The outer tracks Q are preferably of greater length than the tracks P so as to
keep the outer edge of the endless band of slats and plates in proper position when
coming on to the inner tracks.
Adjacent to the hoppers or feed entries R of the machine is a hinged frame S
carrying rollers T, T, or other appliance against which one end or ends of the piece
or pieces of wood under operation abuts, and when a piece of wood is cut down by
the knives to about inch in thickness or just below the centre line of the roller T,
the knives acting on the wood meeting with no resistance force the piece of wood
under the roller and carrying it along to the end of the machine automatically
ejects it through the opening U clear of the machine, a fresh piece or pieces of
wood taking its place to be acted upon by the groovers or scorers and knives
following. The rollers are kept to their working position by suitably arranged
springs T and limited in their downward movement by the stop T or other
device.
The roller frames instead of being hinged as shown may be arranged perpendicular
or otherwise and in other frames so as to be slid up by the wood when sufficiently
cut down, the rollers returning to their working position by springs.
I also arrange, as near as possible to the place where the wood is cut, a knife
cleaner V which consists of a roller or wheel of wood or other material softer than
the knives or cutters, said roller or wheel V being arranged on a hinged frame W
and by gearing or belting X, X', and pullies Y, Y, Y, Y³, driven from the main
driving axle Z to a far greater speed than the knives motion but in the same
direction, so that it will by coming in contact with the knives clean them from any
chips or other debris which might remain thereon.
The pulley bearings B are so arranged as to be adjustable for taking up any
slack of the endless band and preferably by the means shown in Figure 1 by
simply loosening the nuts e', e', and shifting the bearing by moving the screw f1.
9, 9', are bearings for the axle carrying the kuife cleaner frames W and
pullies.
The pullies C, D, are driven at one side of the machine from belting attached to
a fast pulley i fixed on the axle Z of the large pulley D.
n is the loose pulley.
The machine is fed through the openings or hoppers R by hand or other means
of pressure with pieces of wood to a given size between the pullies above the
tracks and the operators holding the top piece or pieces of wood down to give
sufficient resistance to the kuives which cut the bottom piece of wood from
underneath, or a number of pieces of wood may be arranged one above the other to
create weight to give the necessary resistance.
In the first instance just mentioned, the blocks of wood when cut to a thin strip
would be automatically discharged, as heretofore described; but if one, two, or
more blocks are placed upon the block being cut, then said latter named block
would be entirely eaten up, and there would be no need for the roller T.
The product, wood wool, or the like, is guided to outside of the machine by

page_text: chutes k, l, which are arranged directly under the cutting portion of the machine
and with their upper edges at or near the inside tracks, and their lower edges
outside of the machine so that the material, as it is cut, is prevented from falling on
the band, and thus interfering with the action of the machine.
m is a metal plate having openings corresponding to the hoppers R and arranged
above the knife band to give steadiness to the wood and prevent it being moved
sideways from its position during the working of the knives.
Should occasion require, such as when working hard wood, that extra stability
be given to the band, another set of guides may be affixed to the upper or outer
portion of the band or plates to run on tracks arranged under the top of the
machine for which provision is made by extra holes in the band or plates.
By the improvements hereinsetforth, wood wool or similar product of any degree
of fineness or thickness and width can be produced in a rapid and comparatively
inexpensive manner.
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 :-
1. The improvements in and connected with machines for the manufacture of
wood wool or similar product substantially as herein set forth and as represented on
the annexed drawings.
2. So attaching transversely arranged metal slats that a portion of each is
connected directly to an endless band, and the other or extensions therefrom have
other or shorter plates affixed, and to ride on and be guided by tracks on an
underframe some of said extensions carrying the knives or cutters, as set forth.
3. In a machine for manufacturing wood wool and the like, attaching a continuous
row of metal slats transversely on an endless band, each slat being of greater length
than the width of the endless band and carrying metal plates or working faces at
the parts outside of the band, certain slats and plates being provided with knives,
or groovers, or scorers, the slats being kept a slight distance apart by projecting
corners or distancing pieces, and in such a manner that each slat will support its
neighbour edgeways, and thus in conjunction with the guides and tracks form a
complete solid table to give sufficient resistance to the pressure of the knives against
the wood, as set forth.
