PROVISIONAL SPECIFICATION.
Improved Flax Hackle.
JOHN CARROLL Flax Dresser 33 Crocus Street Belfast Co. Antrim Ireland
do hereby declare the nature of this invention to be as follows:-
A wedge shaped slip placed in between hackle pins, longitudinally to press pins
into interstices between each pin at point & running in paralell, rows to each other,
in hackle stock. Such may also be done for machine hackles, by boreing holes in
at angle to throw pins in at point to each other & make closer object to set hackle
pins closer at points, than can be attained, by present system.
And by this form of setting, to take out & clean fine fibred flax free of naps or
lumps such wedge to be held in position by bracket or screw at each end of hackle
stock.

COMPLETE SPECI
CATION.
Improved Flax Hackle.
I, JOHN CARROLL of 33 Crocus Street Belfast in the County of Antrim in
Ireland, Flax Dresser, 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 the hackling of flax, preparatory to the process of
manufacturing the same into yarns, and consists in arranging two or more rows of
pins in the hackle stock so as to converge at the top and to form a single line
of points each of which almost touches those at either side of it, whereby such
points may be set closer than can be accomplished by the system hitherto commonly
practised, and fine as well as coarse fibred flax may be cleaned and rendered free
of naps and lumps.
For this purpose, and for utilizing the hackle stocks at present employed for
hand dressing I place a wedge shaped slip or bar of wood or iron longitudinally
between the second and third rows of pins in the hackle stock, the wedge being
firmly attached, with its thin edge downwards, to the ends of the hackle stock at
each extremity, by means of brackets or screws so as to keep it in position. The
broad or upper side of the wedge is so arranged as to width or position as to place
and retain in line the points of the pins in the first and second, and the third and
fourth rows on the hackle stock.
But in the construction of new hackle stocks I drill or bore the holes in which
the hackle pins in the front and back rows are to be placed at an angle so as to
throw the points of the pins in the first and last rows forward and backward
respectively to the points of the adjacent row of pins, and thus to form single lines
of the points.
And where the backle stocks are furnished with more than three rows of pins
I prefer to employ in the first and second rows shorter pins than are employed in
the other or others of such rows, so that the lines of points in the front and back
of the hackle stocks may be in a lower plane than that of the others.

page_text: In applying my invention to a machine hackle stock I drill or bore the same for
two rows of pins each of which I may set so as to incline towards the other, and
form a single line of points as in the pins of the stocks employed in hand dressing,
or I may drill or bore the stock so that the outer row will bo perpendicular to it,
and the inner row only will be set to incline to the outer row.
And in order that my said invention may be more fully understood I shall now
proceed to describe the figures thereof upon the sheets of drawings hereunto
annexed, the same letters of reference being used throughout all the figures to
describe the same or corresponding parts of the apparatus.
Fig. I. represents a cross section of a machine hackle having the two rows of
pins set in the hackle stock and inclined to each other, so that the points of both
rows form a single straight line.
Fig. II is a front elevation of part of a machine hackle.
Fig. III is a plan of the same.
Fig. IV represents a cross section of a machine hackle having the first row of
pins set perpendicularly in the hackle stock, and the second row only inclined so
that the points of both rows form a single straight line.
Fig. V is a front elevation of the hackle shewn in Fig. IV.
Fig. VI is a plan of the same.
Fig. VII represents a cross section of a hand hackle having the first and last
rows of pins set in the hackle stock and inclined to the rows adjoining them
respectively so that the points thereof form single straight lines, the pins being
shortened, and the points thus being in a lower plane than those of the other rows
of pins in the stock.
Fig. VIII is a plan of part of the hackle shewn in Fig. VII.
Fig. IX represents a cross section of a hand hackle as at present commonly
employed in which an inclination is only given to the second and third rows of pins
in the front and to the corresponding rows of pins at the back of the stock by
means of wedges firmly attached to the ends thereof as before mentioned, and
Fig. X is a plan of part of the hackle shewn in Fig. IX, a. is the hackle stock,
b. b. are the pins and c. c are the wedges I employ for inclining the pins in hand
hackles as at present commonly employed.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed I declare that what I
claim is.
The use of hackle stocks arranged with a double row or double rows of pins so
set or inclined that the points thereof form a single longitudinal straight line in the
manner and for the purposes hereinbefore described and shewn in the drawings
hereunto annexed.
