Improvements in Machinery for Hackling Flax and other Fibrous
Materials.
I, HENRI RYKBOSCH of 26 Rue du Nazaro, Marcq en Baroeul, France,
Spinning Manager, do hereby declare the nature of this invention to be as
follows:-
My invention has reference to machinery for hackling flax or other fibrous
materials and the objects are, first to obtain stricks or tresses of flax or other fibre
capable of producing finer "numbers" than those obtained with ordinary hackling
machines, the classification being raised 10 to 15 "numbers" or more; to enable
weak flax or other fibres to be hackled equally well as hard fibres in the same
machine; to submit the fibres to a preliminary hackling process at a slow or
reduced speed in the first of two coupled machines, the fibres then proceeding to
the second machine in which they are hackled at a greater speed (these speeds. can
be varied at will and made equal if necessary); to prevent the breaking of the ends
of the material before its entry into the machine; and to construct the machinery
without complication, the two coupled machines being actuated by means of one
shaft driven by one belt.
In my improved machinery I couple or combine, as already above intimated, two
hackling machines; these may be either of one type or of different types provided
that the same clamps or holders can be used in both.
The first of these machines, which may appropriately be termed the preparing
machine, gives the material a preliminary hackling at a slow speed, this hackling
having the effect of softening the material while acting upon it. The hackling is
continued in the other machine which may be called the hackling machine proper
and works at a different speed to that of the first machine.
The driving of these coupled machines is effected by means of one shaft which
is actuated by a single belt. The said shaft is preferably placed in line with the
machines in their longitudinal direction and outside same, the two machines being
placed end to end. The hackles of the two machines are each preferably driven
as follows:-A pinion keyed on the pulley shaft drives a permanent intermediate
wheel which gears with a change wheel on the shaft of which is keyed a change
pinion. The said change wheel and change pinion will be varied as may be
required. The change pinion drives one of a pair of wheels which move the straps
that carry the hackles.
The fibres in their clamps or holders are introduced at one end of the first
machine and pass gradually to the other end; as they proceed they are submitted
to the action of hackle pins of gradually increasing fineness and closeness; they
then pass to and through the second machine in which they are again submitted to
the action of pins of gradually increasing fineness and closeness.
If thought desirable two pairs of coupled machines can be connected together.

Improvements in Machinery for Hackling Flax and other Fibrous
Materials.
I, HENRI RYKBOSCH of 26 Rue du Nazaro, Marcq en Baroeul, France,
Spinning Manager, 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 :-
My invention has reference to machinery for hackling flax or other fibrous
materials, and the objects are, first to obtain stricks or tresses of flax or other fibre
capable of producing finer "numbers" than those obtained with ordinary hackling
machines, the classification being raised 10 to 15 "numbers"
or more; to enable
weak flax or other fibres to be hackled equally well as hard fibres in the same
machine; to submit the fibres to a preliminary hackling process at a slow or
reduced speed in the first of two coupled machines, the fibres then proceeding to
the second machine in which they are hackled at a greater speed (these speeds can
be varied at will and made equal if necessary); to prevent the breaking of the
ends of the material before its entry into the machine; and to construct the
machinery without complication the two coupled machines being actuated by means
of one shaft driven by one belt.
The accompanying drawings represent hackling machinery constructed according
to my invention.
Figure 1 is a side elevation, Figure 2 an elevation of the right hand end of the
first of the two coupled machines and Figure 3 an elevation of the left hand end of
this machine.
Figure 4 is a section of the second of the two machines on the line A B of
Figure 1 and
Figure 5 an elevation of the left hand end of this machine.
In my improved machinery I couple or combine, as already above intimated,
two hackling machines X and Y ; these may be either of one type or of different
types provided that the same clamps or holders can be used in both.
The first of these machines X, which may appropriately be termed the preparing
machine, gives the material a preliminary hackling at a slow speed, this hackling
having the effect of softening the material while acting upon it. The hackling is
continued in the other machine Y which may be called the hackling machine
proper and works at a different speed to that of the first machine.
The driving of these coupled machines is effected by means of one shaft D which
is actuated by a single belt C passing over a pulley E.
The said shaft D is preferably placed in line with the machines in their
longitudinal direction and outside same as shown the two machines being placed
end to end. The hackles of the two machines are each preferably driven as
follows: A pinion a keyed at the end of the shaft D (one pinion a for each
machine) drives a permanent intermediate wheel 6 which gears with a change
wheel c on the shaft of which is keyed a change pinion d. The said change wheel
and change pinion will be varied as may be required. The change pinion drives
one of a pair of geared wheels ee the shafts of which actuate the straps F F that
carry the hackles.
The fibres in their clamps or holders are introduced at one end of the first
machine, that is to say, at the part marked 1 and pass gradually to the other end;
as they proceed they are submitted to the action of hackle pins of gradually
increasing fineness and closeness; they then pass to and through the second
machine in which they are again submitted to the action of pins of gradually
increasing fineness and closeness; they leave this second machine at the part
marked 2.

page_text: Although I have stated that the two machines may if desired be driven at the
same speed, this should only be for special reasons; it is of great importance to
drive the second machine at a greater speed than the first for it is chiefly upon this
differential speed that the obtaining of finer "numbers" depends.
If thought desirable two pairs of coupled machines can be connected together.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. In hackling machinery, the coupling together of two machines, substantially
as herein before described, the one machine being a preparing or preliminary
hackling machine and the other a hackling machine proper as set forth.
2. The driving of two coupled hackling machines such as referred to in Claim 1
from one shaft driven by a single belt as set forth.
3. The improved hackling machinery constructed substantially as herein before.
described and represented in the accompanying drawings.
Dated this 5th day of April 1894.
