Improvements in Wool Willows or Machines for the Primary
Loosening and Cleaning of Wool.
1, ARCHIBALD THOMSON, of Springfield Mills, Alloa, in the County of Clackmannan,
North Britain, Manufacturer, do hereby declare the nature of this Invention to be as
follows, that is to say:-
My said Invention has for its object to provide a willow or machine for the primary
loosening and cleaning of wool with improved and simple automatic mechanism for
effecting the intermittent feeding-in and delivering operations.
In machines of the kind for which my improvements are designed a certain quantity
of wool is introduced into the machine by the action of a feed apron or lattice and
feeding-in rollers; the feeding is then stopped whilst the wool taken in continues to
be operated on by the rotating fan or beater of the machine during a suitable period
at the end of which a discharge door at the further side of the machine is temporarily
opened and a quantity of wool that has been operated on is delivered. A further
quantity is next fed in and operated on in a similar manner.
In carrying out my Invention I employ a spurwheel which is in any convenient
way made to rotate at a suitable comparatively slow speed, this spurwheel being in
gear with a pinion giving motion to it. On the wheel there is fitted a toothed seg-
ment or are of a size corresponding to the feeding-in period the remainder of the
circumference corresponding to the period during which the feeding-in is stopped.
The toothed segment gears with a small intermediate spurwheel which is on a stud and
which gears with a pinion on the spindle of the lattice roller and with a pinion on
one of the feeding-in rollers. The toothed segment is not fixed rigidly to the wheel
but is capable of being pressed inwards against a rubber or other spring should its
teeth encounter the outer ends of the teeth of the intermediate spurwheel. The dis-
charge door is opened by means of a rod adjustably connected to it and which is
acted on by a tappet or cam on the boss or shaft of the wheel fitted with the toothed
segment.

Improvements in Wool Willows or Machines for the Primary
Loosening and Cleaning of Wool.
I, ARCHIBALD THOMSON, of Springfield Mills, Alloa, in the County of Clackmannan,
North Britain, 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, that is to say :-
My said Invention has for its object to provide a willow or machine for the primary
loosening and cleaning of wool with improved and simple automatic mechanism for
effecting the intermittent feeding-in and delivering operations.
In machines of the kind for which my improvements are designed a certain quantity
of wool is introduced into the machine by the action of a feed apron or lattice and
feeding-in rollers; the feeding is then stopped whilst the wool taken in continues to
be operated on by the rotating fan or beater of the machine during a suitable period,
at the end of which a discharge door at the further side of the machine is temporarily
pened and a quantity of wool that has been operated on is delivered.
quantity is next fed in and operated on in a similar manner.

page_text: And in order that my said Invention and the manner of performing the same may
be properly understood I hereunto append a sheet of explanatory drawings to be
hereinafter referred to and showing my improvements.
Figures, 1, and 2, on the accompanying sheet of drawings are partial end and side
elevations showing my improvements; and figures 3, and 4, are enlarged views of
details. In these drawings the same reference letters are used to mark the same or
like parts wherever they are repeated.
In carrying out my Invention I employ a spurwheel, A, on one end of a shaft, B,
carried by the framing, C, of the machine. This spurwheel, A, is in any convenient
way made to rotate at a suitable comparatively slow speed being driven by a pinion, D,
on a second shaft, E, deriving its motion from any suitable source. On the inner
side of the wheel, A, there is secured a toothed segment or arc, F, (shown enlarged
in figures, 3, and 4) of a size corresponding to the feeding-in period, the remainder of
the circumference corresponding to the period during which the feeding-in is stopped.
Figure, 3, represents the face of the toothed segment, F, which is applied to the
inner side of the wheel, A, which latter is not shown in figure, 3. In figure, 4, part
of the wheel, A, and of the toothed segment, F, are shown in section. The toothed
segment, F, gears with a small intermediate spurwheel, G, which is on a stud, H, and
which gears with a p'nion, J, on the spindle, K, of the lattice roller and with a
pinion, L, on the spindle, M. of one of the feeding-in rollers. The toothed segment, F,
is not fixed rigidly to the wheel, A, but is jointed on a stud at, N, and is held at its
other end, P, by means of a bolt, Q, passing through a slot, R, in the segment, F, and
fixed in the wheel, A, so that the segment, F, is capable of being pressed inwards
against a rubber (or other) spring, S, should its teeth encounter the outer ends of the
teeth of the intermediate spurwheel, G, when entering into gear with that spurwheel.
The spring, S, is held in a box, Y, bolted to the wheel, A. The discharge door which
is indicated by dotted lines is hinged on a shaft, T, held in the framing, C, and is
opened by means of a rod, U, the outer end of which is adjustably connected to a
slotted lever, W, on one end of the shaft, T, a pin, X, near its other end being acted
on by a wiper or cam, Z, on the boss or shaft, B, of the wheel, A.
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 :-
In a willow or machine for the primary loosening and cleaning of wool, effecting
the intermittent feeding-in, by means of a toothed segment or arc, arranged and
operating substantially as hercinbefore described.
