Improvements in the Process and Apparatus for Removing Burrs and the like from Wool.
Year: 1897

page_text: Improvements in the Process and Apparatus for Removing Burrs and
the like from Wool.
We, SAM JOWETT, of Montserrat Mills, Dudley Hill, near Bradford, in the
County of York, Wool Comber, and JOHN DODSON, of Tong Street, Dudley Hill,
aforesaid, Combing Overlooker, do hereby declare the nature of this invention
to be as follows:-
-
This invention relates to improvements in the process of and apparatus for
removing burrs or the like from merino and other burry wool.
We crush the burrs by means of the machine hereinafter described after the
wool is washed and preparatory to carding. Crushing the burrs at this stage
greatly facilitates their removal during the carding process as they are free to
be extracted or removed from the very commencement of this process.
The machine we employ consists of a suitable screw gill or preparing box and
at the delivery end of the box we fit a pair of crushing rollers between which the
film of fibres passing from the delivery rollers of the box is passed.
These crushing rollers may be located a suitable distance away from the box
delivery rollers and be driven at a greater peripheral speed. The fibres may be
supported in their passage from the box delivery rollers to the crushing rollers
upon an endless apron, and a rotary beater may be employed to throw off the fibres
as they leave the crushing rollers. Any suitable arrangement is provided to
prevent the rollers lapping.
Means are preferably provided for heating the feed apron or feed device of the
box as well as the gills or fallers.

Improvements in the Process and Apparatus for Removing Burrs ana
the like from Wool.
We, SAM JOWETT, of Montserrat Mills, Dudley Hill, near Bradford, in the
County of York, Wool Comber, and JOHN DODSON, of Tong Street, Dudley Hill,
aforesaid, Combing Overlooker, do hereby declare the nature of this invention

page_text: and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:―
This invention relates to improvements in the process of and apparatus for
removing burrs or the like from merino and other burry wool.
We crush the burrs by means of the machine hereinafter described after the
wool is washed and preparatory to carding. Crushing the burrs at this stage
greatly facilitates their removal during the carding process as they are free to
be extracted or removed from the very commencement of this process.
The machine we employ consists of a suitable screw gill or preparing box and
at the delivery end of the box we fit a pair of crushing rollers between which the
film of fibres passing from the delivery rollers of the box is passed.
These crushing rollers are preferably located a suitable distance away from
the box delivery rollers and are driven at a greater peripheral speed. In this
case the fibres are supported in their passage from the box delivery rollers to the
crushing rollers upon an endless apron, and a rotary beater is employed to throw
off the fibres as they leave the crushing rollers. Any suitable arrangement is
provided to prevent the rollers lapping.
To fully describe our invention reference is made to the accompanying sheet
of drawings forming a part of this specification, in which similar letters of refer-
ence indicate corresponding parts in each of the figures.
Figure 1, represents a side elevation of such parts of a screw gill box as are
necessary to illustrate the application of our improvements. The lower part of
the framework is broken away to economise space.
Figure 2, is a plan view of the same.
Figure 3, is a cross section of the delivery rollers of the gill box, the crushing
rollers and certain other parts.
The gill box A is of any ordinary construction and the wool may be fed by
hand on to an endless travelling feed apron travelling over a steam chest B
located inside the apron. It has not been deemed necessary to show the screw
gills, the feed rollers or the feed apron as their use and construction are well
known. Aa apron formed of metal laths or the like linked together is however
preferably used as it permits the heat from the steam chest to reach the wool on
the apron. A steam chest C is preferably placed under the gills.
An endless leather apron D passes between the delivery rollers E, round the
small roller F and guide roller G and carries the wool from the rollers E to the
crushing rollers H and H. As the wool leaves the crushing rollers it is caught
by the rotary beater T and thrown forwards on to the floor. An endless leather
apron mounted on the rollers L and M is provided to assist the rubber R2 in
keeping the roller H from lapping, and the apron D keeps the roller H2 from
lapping. The arrows in Figure 3 show the direction of the motion of the parts.
The roller H2 is mounted in bearings in the standards N, N and the roller H is
supported in bearing blocks 0, 0 hung by the rods P, P to the caps R, R of the
standards. The roller H is adjusted just to clear the roller H2 and allow the
fibre to pass through without damaging it but the rollers are not sufficiently apart
to permit burrs to pass without crushing them. The roller H is made sufficiently
large that by its weight alone it crushes the burrs, but provision may be made
for keeping it down if required.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what I
claim is:
1. The improved means or method of removing burrs from wool by passing
the wool through burr crushing rollers preparatory to carding, substantially as
herein shown and described.

3. The combination with a screw gill box, of the crushing rollers located at
the delivery end of the box, the beater T and the apron D, substantially as herein
shown and described.
