page_text: the ends of which are connected to the supplementary sliding bar F by the upright
brackets N. By means of the band M attached to both the wheel I and the sliding
bar F the reciprocating rotary motion that the wheel receives from the sliding bar C
is transmitted to the sliding bar F.
Instead of the band M it is obvious as explained with reference to the band K
that a rack or other device may be employed for transmitting the movement of the
wheel I to the sliding bar F.
The sliding movement of the supplementary sliding bar F is greater and quicker
than that of the ordinary sliding bar C by reason of the circumference of the face i
of the wheel I which gears with the fixed band K attached to the channel being
less than that of the face which gears with the band carried by the supplementary
sliding bar F. The short travel of one tool length of the ordinary_sliding catch
bar C is thus converted into a long travel of the supplementary bar F sufficient. to
push a holder over the length of two three or more tools at that part of the lift
of the channel when all the flax is carried above the intersection of the hackling
sheets.
The distance of travel of the supplementary sliding bar F in relation to the
ordinary sliding bar C can be adjusted or regulated by the relative diameter of the
two faces of the wheel I. In practice however prefer to make the travel of
the supplementary bar F of the maximum length of the greatest number of the
hackle tools that I wish to skip and for the purpose of skipping or passing the
holders past a fewer number say one two or three tools, I place on the bottom of
the channel an inclined plane O the position of which can be adjusted. The dog or
pawl G depending from the supplementary bar F will come in contact with this
inclined plane O and so be raised to avoid the stud or pin a in the side of the
holder A and pass over it allowing the holder to be actuated only by the dogs or
pawls D of the ordinary bar until the dog or pawl G reaches the end of the incline
when it falls down and engages with the holder carrying it forward the desired
distance.
It is obvious that instead of mounting the wheel I upon the ordinary bar C
(which, however, is the method I prefer) another reciprocating sliding bar may be
used to carry a wheel such as I either moved to and fro by the bar C as it moves
or actuated independently from the same source of motion.
In operation the ordinary sliding bar C will be actuated and caused to move to
and fro in the usual way moving forward the holders A as the dogs or pawls D
come in contact with the pins a. The movement of the bar C will by the action
of the band K rotate the wheel I which it carries and the same will move the
supplementary bar F to and fro a greater distance than the bar C moves.
As the
supplementary bar F moves to and fro the dog or pawl G depending therefrom
(when not raised up by the ping resting on the inclined plane O) will come in
contact with the pins a of the holders A and move the holders a greater distance
than they would have been moved by the ordinary bar C and past the desired
number of the hackle tools so that the flax will miss or skip the action of
such tools.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. The mechanism for traversing the flax holders of hackling machines provided
with an additional or supplementary sliding catch bar actuated at a greater speed
than the ordinary catch bar by means of a wheel with two faces of different
diameters carried by the ordinary or other reciprocating sliding bar the face of
least circumference engaging with a stationary band or rack by which rotation is
imparted to it and the face of greatest circumference imparting motion to the
supplementary catch bar substantially as described.
2. In a machine for hackling flax the combination with the ordinary sliding
catch bar and a supplementary sliding catch bar of the double wheel or pulley with

page_text: faces of different diameters (or two wheels of different diameters) mounted upon
the ordinary or other reciprocating sliding bar, the fixed band or its equivalent
gearing with the face of least circumference and the band or its equivalent gearing
with the face of greatest circumference and attached to the supplementary catch
bar with or without the inclined plane or adjustable race by which the dogs or
pawls are lifted out of contact with the holders substantially as described.
3. In hackling machines the use of an inclined plane or adjustable race attached
to the channel in which the holders slide for the purpose of lifting the dogs or
pawls out of contact with the holders and regulating the number of holders actuated
or the distance the holders are traversed by the supplementary sliding catch bar
substantially as described.
4. In hackling machines the mechanism for traversing the flax holders con-
structed and arranged substantially as described and shown.
