An Arrangement for Cleaning Hackle Pins Used in Machines for
Hackling Flax or other Fibres.
JOSEPH MALCOMSON GREEVES Mill Manager of Glenside Strandtown near Belfast
County Down Ireland and THOMAS LUCAS Mechanic of 212 Grosvenor Road Belfast
County Antrim Ireland do hereby declare the nature of this invention to be as
follows
The object of this invention is to prevent and remove the deposits of dirt which are
liable to form especially on the side of the pins which pass first through the material
being hackled.
This arrangement for cleaning hackle pins while at work in machines for hackling
flax or other fibres consists of a series of brushes in which the bristles are set in rows
and are made to come in contact with the front or cutting side of the hackle pins end
on and at about right angles thereto and as near to the roots of the pins as is
desirable.
The brushes whilst thus in contact with the cutting side of the hackle pins are made
to move along the pins from the roots to the points and thus carry away any dirt and
so prevent its accumulation on the pins.
The brushes act upon that portion of the hackle pins which is untouched by the
ordinary brushes employed for removing the tow thus the entire surface of the pins is
effectually cleaned.
This is accomplished by making the brushes of the same length and of a pitch cor-
responding with the series of hackles to be cleaned the brushes being carried on bars
which slide to and fro in slots formed in a plate and radiating from a common centre
round, which they are carried the to and fro motion being given by pivots on the ends
of the bars which move in fixed grooves of suitable shape.
The slotted plates which carry the brush bars are caused to rotate by being con-
nected by suitable geering to the shafts which carry or drive the hackles thus the
hackles and brushes move contemporaneously.
When the hackles arrive at that portion of their passage in which they are out of
action with the material and freed from tow by the usual means for this purpose the
hackles are then submitted to the brushes for removing the dirt.
This arrangement of brushes is applicable to hackling machines whether the tow is
removed from the hackles by stripper bars or by brushes and doffers.
This arrangement of brushes can also be employed for cleaning hackles when out of
the machines by mounting them temporarily on endless sheets corresponding in pitch
with the cleaning brushes.

COMPLETE SPECIFICATION.
An Arrangement for Cleaning Hackle Pins Used in Machines for.
Hackling Flax or other Fibres.
We JOSEPH MALCOMSON GREEVES Mill Manager of Glenside Strandtown near Belfast
in the County of Down Ireland, and THOMAS LUCAS, Mechanic of 212 Grosvenor Road
Belfast in the County of Antrim Ireland, do hereby declare the nature of this inven-
tion 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 this invention is to prevent accumulation and remove any deposit of

page_text: dirt especially on the side of the pins which first pass through the material being
hackled.
This arrangement for cleaning. hackle pins while at work in machines for. hackling
flax or other fibres consists of a series of brushes in which the bristles are set in rows
and are caused to come in contact with the front or cutting side of the hackle pin's 5
end on and at about right angles thereto and as near to the roots of the pins as is
derirable.
The brushes whilst thus in contact with the cutting side of the hackle pins are made
to move along the pins from the roots to the points and thus carry away any dirt and
so prevent its accumulation on the pins.
The brushes act upon that portion of the hackle pins which is untouched by the
ordinary brushes employed for removing the tow thus the entire surface of the pins is
effectually cleaned.
This is accomplished by making the brushes of the same length and of a pitch cor-
responding with the series of hackles to be cleaned the brushes being carried on bars
which slide to and fro in slots formed in a plate and radiating from a common centre
round which they are carried the to and fro motion being given by pivots on the ends
of the bars which move in fixed grooves of suitable shape.
The slotted plates which carry the brush bars are caused to rotate by being con-
nected by suitable gearing to the shafts which carry or drive the hackles, thus the
hackles and brushes move contemporaneously.
When the hackles arrive at that portion of their passage in which they are out of
action with the material and freed from tow by the usual means for this purpose, the
hackles are then submitted to the brushes for removing the dirt.
This arrangement of brushes is applicable to hackling machines whether the tow is
removed from the hackles by stripper bars or by brushes and doffers.
This arrangement of brushes can also be employed for cleaning hackles when out
of the machine by mounting them temporarily on endless sheets corresponding in
pitch with the cleaning brushes.
Such being the nature and object of this our said invention the following is a
complete description of same reference being had to the accompanying drawings in
which
Fig. 1 is a section of the arrangement for cleaning hackle pins together with so much
of the hackle sheets,, brushes and doffers as is necessary to show the application.
Fig. 2 is a section of the end portion of the arrangement through the line on
fig. I.
Figs. 3, 4, and 5 are detached views of parts.
!...
The brushes are made of the same length and of a pitch corresponding with the
series of hackles a to be cleaned the brushes being carried on bars which are
caused to slide, to and fro in slots e formed in a plate c¹ and radiating from a common
centre round which they are carried, the to and fro or sweeping motion of the
brushes being given by the pivots 62 on the ends of the bars 6 which move in
fixed grooves d of the cam plate d' fixed to the framing of the machine and its
grooves. being made of suitable shape to give the to and fro motion at the proper
time in their revolution...
The first portion of the path Y-Z brings the brushes into position before the
hackles, and the other portion of path Z-W drawing them away gives the sweeping
action. A
The slotted plates which carry the brush"
b bars 6 are keyed on a shaft 'm which
is caused to rotate by being connected by suitable gearing e to the shafts,a which
carry or drive the hackles.
The action is as follows
וני
"
Firstly the brushes" are advanced in front of the pins 'allowing the pins to overtake
the brush then the latter is drawn alon
along from the root to and off the point of the pins,
and by the employment of the combined rotary and radial motions' sufficient line is
afforded for the requisite movements, and correct timing of the movements of the hackle
pins and cleaning brushes is ensured:

page_text: When the hackles a arrive at that portion of their passage in which they are out of
action with the material and freed from tow by any of the usual means for this
purpose the hackles a are then submitted to the brushes b for removing the dirt.
In practice any number of brushes short of the full compliment may be used
according to the ease with which the pins are cleaned.
This arrangement of brushes 6 operated as described is applicable to backling
machines whether the tow is removed from the hackles a by stripper bars or by
brushes and doffers h.
In the portion of a hackling machine shewn in fig. 1, brushes f and doffers h
are employed to remove the tow from the hackles a.
This arrangement of brushes b operated as described can also be employed for
cleaning hackles when out of the machine by mounting them temporarily on endless
sheets corresponding in pitch with the cleaning brushes.
For the purpose of removing any tow that may accumulate upon the brushes b
we employ a line of pins / that can be brought into contact with the brushes b
by means of one movement of a hand lever and drawn therefrom by the reverse
movement of k¹ thereby stripping adhering fibres from the bristles.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed we declare that what we
claim is
The employment of brushes for purpose aforesaid having the rotary and radial
movements imparted thereto by means such as the plates c and d or their
equivalents operating and operated in manner described and substantially as
illustrated.
