Improved Apparatus to be Employed for Winding Work on Beams,
or Unwinding Warps or Fabrics from Beams.
I HORACE ARTHUR FISKER, Newcastle Circus, the Park, Nottingham, Lace
Manufacturer, 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 :-
Figure 1 shows a front view of my improved apparatus as applied to the right end
of the work beam of a twist lace machine.
Figure 2 shows a plan of the same.
The ordinary method of winding up the work beam in a twist lace machine, makes
it necessary to change the toothed wheel at the end of the axle of a worm from two
to four or more times in the length of a piece, increasing the number of teeth in the
wheel, as the diameter increases with the work wound on the beam.
To avoid changing the wheel and yet ensure an automatic and equal adjustment of
the winding up, from end to end of the piece I employ an arm A rocking on an
axle secured in the framing A¹ of the machine, the lower end of the arm A is hinged
to the upper end of a link B, both rocking on an axle secured in the lower end of a
reciprocating arm C the arms A and C being of equal length, the lower end of the
link B is hinged to the right end of a lever D, carried on an axle D', at the centre of
its length, secured to the framing of the machine. The left end of the lever D forms
a bearing, in which a stud projecting from a forked bracket D2 rocks, the bracket
supports a roller D³ which revolves on and is pressed up to the work on the beam G
by a spring D secured to the framing, the upper end of the arm C, carries an axle
on which the upper end of a rod E and the outer end of a rod F rocks. The rod E
is capable of adjustment in length and is caused to rise and fall, by a suitable cam, or
by the operation of the jacquard in the usual way.
The inner end of the rod F, either carries a friction clutch F', to give a certain
motion to a friction wheel F, secured on the axle F³ of a worm which gears with a
toothed wheel F attached to the end of the work beam's axle, or a click or driver
may be employed to move a toothed wheel secured on the worm axle, instead of a
friction clutch and wheel.
When employing the above described apparatus for winding up work on the beam G,
it is adjusted in the following way.
When commencing with the work beam empty the lever D stands horizontal the
roller D³ pressing on the empty work beam.
The arms A and C coincide at the centre of the upward motion of the rod E in
such a position that they make equal angles with the rods E and F.
Then as the diameter of the beam G increases with the work wound on it, the
outer end of the lever D raises the link B and the centre on which the lever C rocks,
thus lessening the feed of the friction or toothed wheel by which the worm gearing
in the worm wheel F is caused to revolve, in exact proportion to the increased
diameter of the work on the beam. Thus having once regulated the upward stroke
of the rod E to produce a certain quality of work, the same quantity will continue
to be made until the rod E is readjusted for another quality.
When unwinding a warp from a full beam, the lever D stands in such a position
that when the roller D³ is pressed on the warp the outer end of the lever D is raised a
distance above a horizontal position equal to the difference in radius of the beam
empty and full. The lever D gradually falling till it is in a horizontal position when
the beam is empty.

page_text: The centre on which the lever Crocks will as it falls increase the feed of the friction,
or toothed wheel by which the beam G is revolved in exact proportion to the decreased
diameter of the warp.
Although I have only described my improved apparatus as applied to twist lace
machines, it is equally applicable to winding up the work beams in other fabric
making machinery, and to automatically control the letting off or unwinding of warp
or fabrics in other machinery.
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 :-
1. The construction and employment of an automatic self-adjusting winding up
apparatus, substantially as described and illustrated in the Drawings annexed.
2. The construction and employment of an automatic self-adjusting unwinding
apparatus, substantially as described and illustrated in the Drawings annexed.
