PROVISIONAL SPECIFICATION.
An Apparatus for use in Locking or Clamping the Fibre Holders of
Hackling and other like Machines.
I, MAURICE CHARVET of Armentières, Nord, France, Flax Spinner, do hereby
declare the nature of this invention to be as follows:-
My invention consists of an apparatus for use in locking or clamping the fibre
holders of hackling and other like machines, and its object is to effect the locking
or clamping automatically.
The said apparatus consists of a vertical rod to which an up or down movement
can be imparted from any suitable part of the hackling or other machine. This
rod which can also be caused to rotate on its axis by means of a pinion and rack
has at its lower end a socket to receive a square nut which socket rotates with
the rod. The pinion is keyed on the rod in such manner that the rod can move
longitudinally therein.
One part or half of the fibre holder has guide pins passing through holes in the
other part or half. A screw bolt also passes through the two parts and the nut
already referred to is fitted to it.
The apparatus works as follows: The fibre having been placed between the
parts of the holder this is placed horizontally under the rod; the rod descends so
that the socket fits over the nut, the descent of the rod then stops and it is caused
to rotate by the rack and pinion. This rotation is transmitted by the socket to the
uut which is consequently screwed up so as to lock or clamp the holder. The rod
then rises and frees the clamped holder which can then be moved to the part of the
machine where the fibre has to be operated upon.
One advantage due to this invention is that the fibre is always clamped to an
equal and pre-arranged extent in the holders and that the usual key for clamping
or locking by hand is dispensed with.

COMPLETE SPECIFICATION.
An Apparatus for use in Locking or Clamping the Fibre Holders of
Hackling and other like Machines.
I, MAURICE CHARVET of Armentières, Nord, France, Flax Spinner, 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 consists of an apparatus for use in locking or clamping the fibre
holders of hackling and other like machines, and its object is to effect the locking
or clamping automatically.
The apparatus is represented in the accompanying drawings.
Figure 1 shows it in elevation together with a fibre holder.
Figure 2 is a section on the line 1, 2 of Figure 1,
Figure 3 is a side view and Figure 4 a plan of the fibre holder.
The apparatus consists of a vertical rod A to which an up and down movement
can be imparted from any suitable part of the hackling or other machine, to which
it is connected by means of the joint at B. This rod which can also be caused to
rotate on its axis by means of a pinion E and rack F has at its lower end a socket C

page_text: to receive a square nut D which socket rotates with the rod A. The pinion E is
keyed on the rod A in such manner that the rod can move longitudinally therein.
JJ is the fibre holder; the part or half J has guide pins K. K passing through
holes in the other part or half J. A screw bolt L also passes through the two
parts, and the nut D already referred to is fitted to it. H and I are guides for the
rod A. G is a stop to limit the movement of the rod.
The apparatus works as follows:-The fibre having been placed between the
parts JJ of the holder this is placed horizontally under the rod A, the rod then
descends so that the socket C fits over the nut D; the descent of the rod now
stops and it is then caused to rotate by the rack F and pinion E, the rack being
driven from the hackling or other machine. This rotation is transmitted by the
socket to the nut D which is consequently screwed up so as to lock or clamp the
holder J J. The rod A. then rises and frees the clamped holder which can then
be removed to the part of the machine where the fibre has to be operated upon.
One advantage due to this invention is that the fibre is always clamped to an
equal and pre-arranged extent in the holders, and that the usual key for clamping
or locking by hand is dispensed with.
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 :-
The apparatus constructed and acting substantially as herein before described for
use in locking or clamping the fibre holders of hackling and other like machines.
