Improvements in Machines for Hackling Flax and other like Fibres.
I, JOHN ERSKINE, of Wolfhill Mill, Ligoniel, Belfast, Ireland Manager, do
hereby declare the nature of this invention to be as follows:-
This invention relates to machinery for purpose aforesaid, and comprises
improvements on Patent granted to Applicant 8th May 1889 No. 7695 to be
employed in conjunction with a fixed stationary, or a raising or a lowering
"channel," and lowering traversing or rotating hackles and nippers or cutters for
hackling and for "ending" the fibre.
According to this my invention, sliding or sliding and reciprocating bars are
mounted within guides, or in slots, the said guides or the sliding or reciprocating
bars being provided with bowls or runners for reducing friction and carry one, two
or more hackles either in pairs or single hackles the nipper ends of the sliding or
reciprocating bars are preferably connected by straps or chains passing over
pulleys and provided with balance weights and receive the requisite movement
preferably through connecting rods operated by discs, cranks, or cam plates, or the
lower portion or lengths of said bars may have a reciprocating and an end wise
motion towards and from each other in order to insert cr pass the hackles through
and along the fibre the hackles being connected to, or operated by the said bars.
Or in conjunction with a fixed or stationary or a raising or a lowering "channel"
the hackles may be affixed to endless sheets, link chains or spaced around bosses
or wheels, or worked by screws, similar to screw gills but some of the parts having
preferably intermittent or variable motion imparted by ratchet and catch cam plate
or the like so as to afford the requisite dwell whilst the nippers or cutters are
66 ending" the fibre.
It is desirable the hackles should be arranged on parallel lines overlapping a
little on the same or separate planes or spaced so as to just clear each other. The
ending nippers or cutters (straight or spiral knives) may be attached to and receive
their motion from the connecting rods referred to, or they may have an independent
motion imparted to them from any convenient going part of the machine.
The improved apparatus or some of the parts herein set forth may be applied to,
and work in conjunction with an ordinary hackling or dressing machine, or sheet
machine or may be constructed on separate framework and be employed apart
from the ordinary machines just referred to, or some classes of existing hackling
machines may readily be altered to embrace some of the improvements herein
mentioned.

mprovements in Machines for Hackling Flax and other like Fibres.
I, JOHN ERSKINE of Wolfhill Mill, Ligoniel, Belfast, Ireland 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:-
This invention relates to machinery for purpose aforesaid and comprises
| improvements on Patent granted to Applicant 8th May 1889 No. 7695 to be

page_text: employed in conjunction with a fixed stationary, or a raising or a lowering
"channel" and lowering traversing or rotating hackles and nippers or cutters for
hackling and for "ending" the fibre.
According to this my invention sliding or sliding and reciprocating bars are
mounted within guides, or in slots, the said guides or the sliding or reciprocating
bars being provided with bowls or runners for reducing friction and carry one, two
or more hackles either in pairs, or single hackles the nipper ends of the sliding and
reciprocrating bars are preferably connected by straps or chains passing over
pulleys and provided with balance weights and receive the requisite movement
preferably through connecting rods operated by discs, cranks or cam plates or the
bars have a reciprocating and an endwise motion towards and from each other in
order to insert or pass the hackles through and along the fibre. Or in conjunction
with a fixed or stationary or a raising or a lowering "channel" the hackles may be
affixed to endless sheets link chains or spaced around bosses or wheels, or worked
by screws similar to screw gills but some of the parts having preferably intermittent
or variable motion imparted by ratchet and catch cam plate or the like so as to
afford the requisite dwell whilst the nippers or cutters are "ending" the fibre.
It is desireable the hackles should be arranged on parallel lines overlapping a
little and on nearly the same planes or spaced so as to just clear each other. The
ending nippers or cutters (straight or spiral knives) may be attached to and receive
their motion from the connecting rods referred to, or they may have an independent
motion imparted to them from any convenient going part of the machine.
The improved apparatus or some of the parts herein set forth may be applied to
and work in conjunction with an ordinary hackling or dressing machine or sheet
machine or may be constructed on separate framework and be employed apart
from the ordinary machines just referred to or some classes of existing hackling
machines may readily be altered to embrace some of the improvements herein
mentioned.
Such being the nature and object of my said invention the following is a
complete description of same reference being had to the accompanying drawings
in which
Figs. 12 and 3 are elevations of the apparatus for hackling or combing.
Fig. 1 being most suitable for machines having short traverse or lift and fall of
"channel" and Fig. 3 is applicable to fixed channels as well as raising and lowering
channels one side being open for admittance of fibre as shewn by dotted line.
Fig. 4 is a like view of the apparatus for "ending.".
Fig. 5 is a modification of Fig. 4.
Fig. 6 is view of spiral and straight edge knife for "ending."
The
At 1-1, are sliding bars mounted on runners so as to move freely in slots formed
in the uprights 2. 2. the bars 1. 1. carry the hackle pins 3.. The back of each of
the bars 1, 1. is connected by strap cord or chain passing over pulleys 5, 5. and
provided with balancing weights 6. The requisite vertical movement is imparted
to the hackle 3 by means of the connecting rod 7 operated from crank pin disc or
cam plate as at 8. 8. whilst the opening and closing movements of said hackles is
effected through the arms, 9. 10 link 11 and arm 12 on the axis 13 14.
hackles 3 are tippled as ordinary and cleaned on the brushes 15. 16. Or instead of
the hackles 3 just described there may be employed in conjunction with fixed or
stationary channels, or in conjunction with raising and lowering channels hackle
pins affixed to shafts or cross bars 17 and the latter carried by endless sheets or
chains 18 working over pulleys (see Fig. 3) or the hackles 3 may be applied at
spaced intervals of the diameter of rollers 19 and be provided with cleaning brushes
as at 20 (see Fig. 2) the pins being so spaced and arranged as shewn that the pins
of each series enter the fibre almost on the same plane that is to say directly
opposite each other instead of alternately at intervals and that the pins may if
desired slightly overlap each other.
The above are examples of devices to be employed in combination with fixed or
removeable channels for effecting the hackling of the fibre.

page_text: The
For operating the "ending" nippers for pulling and breaking off the ends I
employ connecting rods 1-1 (see Fig. 4) working through guides 2.2. and
attached to the nipping arms 3ª, 3 the amount of movement of the arms 3ª, 3ª being
determined by the collars 4, 4 which are adjustable on the rods 1-1.
arms 3,3 are mounted on the axles or centres 5.5 said arms having a counter
balance weight and each time the channel ascends and descends the arms 3, 3ª are
lifted and depressed on the axis 5. 5. (moving to the position shewn by dotted
lines) they then catch nip and break off the ends of the fibre. At 21. 22. are a
pair of pressers which may be attached to the frame of the ordinary holder, and
raised and removed thereby against runners 23. 24. the runner 23 being on a fixed
stud, the runner 24 being carried on a sliding frame or centre or centre balance
lever these presses are for purpose fully set out in Specification of Letters Patent
Number 76959 granted to the present Applicant.
The arms 3*3* (see Fig. 5) may form portions of a circle or segment and be
provided with corrugated or serrated nipping surfaces for nipping and pulling off
the ends motion being derived from the rods 1-i as described.
And it will be seen that the devices for hackling such as illustrated by Figs. 2
and 3 are applicable for ending it being provided that instead of the pins or
hacklers sharp cutting edges are employed between which the ends will be nipped
held and pulled out or cut off. Suitable knives or cutting surfaces for purpose
aforesaid are spiral knives similar to those used on cropping machines, or perpetuals.
The straight knife (Fig. 6) being connected to a rocking lever operated by rod
and crank or cam so that the knife opens intermittently clearly of the circular
knife so as to admit the next and succeeding length of fibre to be ended and in
combination with such device it must be understood that the raising and lowering
"channel" is to be employed.
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. The general construction arrangement and combination of parts (for purpose
of hackling flax and other like fibres) as herein fully described and illustrated by
Figs. 1 2. 3 of annexed drawings.
2. Hackles mounted in a sliding frame such as 1. operated vertically by rod and
crank and reciprocated by levers and links as herein fully described and illustrated
by annexed drawings.
3. The appliances illustrated by Figs. 2 and 3 and employed in combination
with the raising and lowering "channel for purpose herein set forth.
"
4. The improved apparatus for "ending" Hax and other like fibres illustrated
by Figs. 4. 5. 6 of annexed drawings and herein fully described.
