PROVISIONAL SPECIFICATION.
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 further improvements in machines for purpose aforesaid
for which Letters Patent No. 7695 dated 8th May 1889 were granted to the present
applicant.
According to this invention a second or duplicate pair of hackles or combs for
imparting additional combing of the "ends" are employed, these being mounted
upon levers in conjunction with the hackles described in Specification referred to,
or they may have separate mountings. The said additional hackles are held in
operating position, and are tumbled or moved out of the way as required by the
action of a cam slot formed in the plates or mountings of said combs. Or the said
combs may be held in position by balance weights but in either case their position
is adjustable to the requirements of staple of different lengths.
The breaking rollers are scored or cross cut at an angle over their surfaces,
which materially adds to their efficiency, and the larger of such rollers I find it
advantageous to drive at an increased speed than the smaller one, and in some
cases I employ a set of such rollers at each end of the combs.

Fibres.
1 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 further improvements in machines for purposes aforesaid
for which Letters Patent No. 7695 dated 8th May 1889 were granted to the present
applicant.
According to this invention a second or duplicate pair of hackles or combs for
imparting additional combing of the "ends" are employed these being mounted
upon levers in conjunction with the hackles described in Specification referred to,
or they may have separate mountings. The said additional hackles are held in
operating position, and are tumbled or moved out of the way as required by the
Or the said
action of a cam slot formed in the plates or mountings of said combs.
combs may be held in position by balance weights but in either case their position
is adjustable to the requirements of staple of different lengths.
The breaking rollers are scored cross cut or slightly grooved at an angle over
their peripheries and the larger of such rollers I find it advantageous to drive at a
greater surface speed than the smaller roller and in some cases I employ a set of
such rollers at each end of the comb.
Such being the nature and object of my said invention the following is a

rawing
which:-
Fig. 1 is end view of hackling ending machine having my improvement
applied thereto.
Fig. 2 is an enlarged view of the duplicate hackles and their carrying arm
opened, or drawn apart.
Fig. 3 is an enlarged view of one of the upper pair of hackles and of its carrying
arm and cleaning brush.
Fig 4 is a like view of one of the lower pair of hackles on the same carrying
arms as hackle shewn at Fig. 3 and shewing clearing brush.
Fig. 5 illustrates in elevation like duplicate pair of hackles mounted upon sliding
plates.
At 1 is a cam plate driven from any convenient going part of the machine aud
which by anti-friction bowl 2 rocks the arm 3 on its fulcrum 4-and by links 5 and 6
opens out or extends laterally the arms 7-8 to the position shewn by Fig. 2 the
return motion or closing of said arm is effected by the counterbalance weight and
lever 9.
At 11. 11, are the upper pair of hackles carried and working on the studs 21. 21
(latter adjustable in slot 22) the said hackles 11-11 being dropt or tilted to the
position shewn at Fig. 2 by reason of the outward or expanding movement of the
arms 7-8 and by means of the parts 11*11* which are free to move in a slide
formed in parts 11° 11° parts 11" 11" carry at one end the brushes 13. 13 and rock
on the stud 20 adjustable in the slot 22. When the arms 7. 8 expand the stop
pieces 11° 11° come in contact with the fixed pins 11ª 11ª the slides 11 11
hackles 11. 11 brushes 13. 13 and counterbalance levers 10. 10 are tilted to the
position shewn by Fig. 2 the brushes 13. 13 clear off any residum and soon as
the arms 7, 8 approach each other, the stops 11° 11° are carried away from the
pins 11, 11d and the weighted arms 10. 10 return the hackles and parts to the
position shewn by Figs. 1-3—4.
Referring now to the lower pair of hackles 12. 12 best seen at Figs. 2 and 4
the hackles are carried on slotted arms 18. 18 latter are mounted and free to tilt on
the studs 19. 19 the tilting being effected through the expanding movement of the
arms 7. 8 fixed pins 19" 19" and the cam slots 17. 17 the sliding and tilting action
of the brushes 14. 14 for clearing the said hackles being effected by the rods, fixed
at 17 so that as the arms 7. 8 expand, the rods 24 push the slides 25 carrying the
brushes 14. 14 forward and the brushes are tilted along with the slotted arms 18. 18
thereby clearing the hackles.
The studs 19. 19 are each fixed in a plate (shewn by dotted line) attached to
the arms 7. 8 said plates being adjustable vertically on the said arms according to
requirements of various length of staple.
Tow catches A. A-B. B. are employed (in connection with the duplicate pairs
of hackles and brushes) operated as above described as set forth in Specifica-
tion 7695 of 1889. The duplicate tow catchers A. A. B. B. are connected
together by the links C.
It is obvious that in lieu of the slots formed in the plates or mountings 18. 18 of
the combs or hackles that such hackles or combs may have separate mountings and
that a cam groove such as 24 (see Fig. 5) may by acting on the pin 25 operate the
slide plates 26 to which the duplicate hackles 11. 12 are attached said plates 26
being carried in slide supports 27 bolted to the gables in such case the duplicate
hackle combs 11. 12 may have a tumbling motion, but such motion is not
indispensable as, the said hackles may be worked by being caused to slide to and
fro, or in and out. Both cam plates 24 may be driven or one only of said plates
may be driven and motion be transmitted from one to the other by chain and
pulley as shewn by the drawing Fig. 5 the weights 29. 29 are for ensuring the
closing of the duplicate hackles, at 30 are stop pieces against which the slide plates
rest when brought together by the weights.
The breaking rollers are scored roughed cross cut or slightly grooved at an angle

page_text: over their surfaces which materially adds to their efficiency and the larger of such
rollers I find it advantageous to drive at a greater surface speed than the smaller
roller and in some cases I employ a set of such rollers at each end of the combs.
It is obvious that the upright arms 7. 8 may be operated both ways by cam
plate but I prefer the single acting cam and the lever and weight 9 as described.
The improvements herein described are applicable whether used in conjunction
with an ordinary hackling machine or they may be employed as separate and
independent.
Having now particularly described and ascertained the nature of my invention
and in what manner the same is to be performed and carried into practise 1
declare that what I claim is :-
1. The employment of duplicate pairs of hackles or combs for purpose set forth
and operated as and by means herein fully described and illustrated by Figs. 1. 2
and 5 of annexed drawings.
2. The employment of duplicate pairs of hackles in combination with and
mounted upon and carried to and fro or in and out by means of sliding plates as
herein fully described.
