Improvements in Shakers or Willeys employed in Removing Dust
from Rags, Shoddy, Flocks, or other Fibrous Materials.
I, JOHN ILLINGWORTH, of the Ridings Mill, Whitelee, Batley, in the County
of York, Flock Manufacturer, do hereby declare the nature of this invention to be
as follows:-
.This invention has reference to that class of machine commonly called shakers
or willeys and which are employed to remove dust from flocks, shoddy and the
like. According to the present construction of machine a revolving spiked cylinder.
is employed within suitable framework for carrying and shaking the materials, a
fun is also employed for carrying off the dust. The revolving spiked roller forces
the fibres out of the machine through a grate which in practice both breaks the
fibre and consolidates it. The object of my invention is to remove the dust and
shake the fibre without breaking the staple and without consolidating it.
In constructing a machine according to my invention I employ a cylinder
preferably without teeth, the periphery of which is perforated. The fibre to be
treated by this machine is arranged to fall upon the top of the revolving perforated
cylinder which shakes and carries the fibre around, discharging it at any con-
venient part, and I employ an exhaust fan which draws the dust through the
perforated cylinder and carries it away through piping to any suitable place
prepared for it. In consequence of drawing the dust and air through the
perforations in the cylinder, the loose fibre has a tendency to adhere to, or stick
onto the periphery of the cylinder and to be carried round with it, I therefore fix
a segment or bar within the cylinder arranged close to the underside of the
perforated sheeting, so that the exhaust fan cannot draw air through the
perforations at the part covered by the segment, consequently the fibre will not
adhere or stick at this particular point whereby I am enabled to strip the fibre or
cause it to leave the cylinder. The fibre may be stripped from the cylinder by means
of an ordinary form of doffing comb or by means of revolving brushes, or a stationary
pad or other suitable devices may be employed for that purpose. One end of the
revolving perforated cylinder is made with an opening from which to draw the dust
on it entering therein. The cylinder end is flanged and is borne by and runs upon
a suitable pedestal. By drawing the dust through a perforated cylinder as herein
described, the flocks or shoddy is not broken or hardened as is the case with the
present construction of the machine but the staple remains unbroken and it leaves
the machine in a light and lofty condition and will be found useful for being
manufactured into the yarn or for upholstery and other like purposes. Although
I have described the use of a perforated revolving cylinder without spikes or teeth,
the said perforated cylinder may have rows of teeth projecting from it, but between
the rows of teeth the cylinder must be perforated.

Improvements in Shakers or Willeys employed in Removing Dust.
from Rags, Shoddy, Flocks, or other Fibrous Materials.
I, JOHN ILLINGWORTH, of the Ridings Mill, Whitelee, Batley, in the County
of York, Flock 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:-
This invention has reference to that class of machine commonly called shakers
or willeys and which are employed to remove dust from flocks, rags, shoddy and
the like.
According to the present construction of machine, a revolving spiked cylinder is
employed within suitable framework for carrying and shaking the materials.
This spiked cylinder is partly surrounded by circular grates covered with fine or
open wire work and the dust is drawn out of the rags or fibres through these
grates by means of a fan. When the material is light the "willey" has to be
worked full of material in order to keep the wire clear and allow of the proper
working of the fan which causes the staple of the fibre to be broken and
consolidated.
The object of my invention is to remove the dust and shake the fibre without
breaking the staple and without consolidating it.
My invention will be more fully understood by reference being made to the
accompanying drawings forming a part of this Specification, wherein
Fig. 1 is a cross section of my improved willey or shaker and Fig. 2 is front
elevation of same partly in section.
A is the cylinder or shaker having a flange a at one end which engages with
and is capable of revolving on a hollow bearing b and secured at the opposite end
to a shaft B supported in bearing e said shaft being driven by pulley and strap
(not shewn) in the ordinary way. C is the framing which encloses the cylinder
provided with an opening C₁ for the delivery of the materials. The periphery of
the cylinder A is perforated or is formed of iron wire of suitable mesh secured to
flanges D and the ends of the cylinder are closed in. The fibre to be treated by
the machine is delivered direct from the rag machine by pipe E and falls upon the
top of the revolving perforated cylinder which shakes and carries it around until it
is stripped by the revolving card covered roller F which deposits it onto the floor
or into a suitable receptacle placed to receive it. The dust in the fibre is drawn
through the perforations or openings in the periphery of the cylinder by means of
an exhaust fan G supported on a bracket G₁ and secured to the bearing or
pedestal at one side of the machine which has an opening I therein corre-
sponding to an opening in the side of the fan box, so that the dust drawn through
the periphery to the interior of the cylinder passes through the opening I and is
discharged by the fan at the pipe K, which conveys it away to any suitable
place.
Instead of a revolving card covered roller being employed to strip the fibre off
the cylinder A, I may employ a revolving brush or a pad or comb or other suitable
devices for this purpose.
The roller or brush F is driven by strap from the fan shaft.
At Figs. 3 and 4 I shew a modification of the means for bringing about the
discharge of the fibre from the cylinder, although I do not prefer to use it.
In this case the shaft B is stationary being secured by a cap to the neck in the
hollow bearing b, and supported loosely in a neck d at the opposite side of
the machine. The cylinder A is driven by strap and pulley mounted on the short
shaft or pin B' secured in one end of the hollow tube or bush e.
On the shaft B
are mounted two or more segments L to which a plate M is secured arranged close
to the perforated sheeting or periphery of the cylinder. The tendency of the

page_text: action of the exhaust fan is to cause the fibre to adhere to the periphery of the
cylinder, but at the point covered by the plate M the exhaust fan cannot draw air
through the perforations and consequently the fibre falls off onto the floor.
By drawing the dust through a perforated cylinder as herein described, the
flocks, rags, or shoddy are not broken or hardened as is the case with the present
construction of the machine but the staple remains unbroken and it leaves the
machine in a light and lofty condition and will be found useful for being
manufactured into yarn or for upholstery and other like purposes.
Although I have described the use of a perforated revolving cylinder without
spikes or teeth, the said perforated cylinder may have rows of teeth projecting
from it, but between the rows of teeth the cylinder must be perforated.
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 :-
•
In shakers or willeys for removing dust from rags, shoddy, flocks or other
fibrous materials, the combination with an exhaust fan drawing from the interior
of the machine of a perforated cylinder with or without one or more rows of
teeth or spikes and means for removing the fibre therefrom substantially as shewn
and for purposes described.
