PROVISIONAL SPECIFICATION.
Improvements in or connected with Machinery Employed for
Cropping or Shearing Worsted and other Textile Fabrics.
We, ALFRED SYKES, Cloth Finisher, and W. E. YATES LIMITED, Woollen
and Worsted Manufacturers, all of Bramley, near Leeds, in the County of York,
do hereby declare the nature of this invention to be as follows:-
The object of this invention, is to actuate the revolving cutter in such a manner
that the cropping operation is more perfectly performed, uneven wear in the bushes
or bearings of the said cutter is prevented, and the fixed horizontal knife is kept
perfectly smooth throughout its length.
According to our invention, we provide a suitable flanged disc, which is situated
on the shaft of the cutter outside the bearings. A rocking bell crank lever is
fulcrumed to a bracket on the frame of the machine, in such a manner that one
end of the said lever passes in between the flanges of the disc, whilst the other end
engages with a suitable cam situated on the drawing roller shaft, or on some other
convenient moving part of the machine.
On the machine being set in motion, a reciprocating movement is given to the
revolving cutter, through the medium of the parts above described. This combined
revolving and reciprocating movement crops the material under operation in a
more effectual and efficient manner, whilst at the same time the steady backward
and forward movement of the cutter shaft prevents uneven wear of the bushes,
and grooving of the fixed horizontal knife is also obviated by the constantly varying
position of the revolving cutter.
It must be clearly understood that we do not confine ourselves to the particular
cam motion described, as any suitable mechanism may be employed for reciprocating
the revolving cutter.

Improvements in or connected with Machinery Employed for
Cropping or Shearing Worsted and other Textile Fabrics.
We, ALFRED SYKES, Cloth Finisher, and W. E. YATES LIMITED, Woollen
and Worsted Manufacturers, both of Bramley, near Leeds, in the County of York,
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 :-
The object of our invention, is to construct machinery for cropping or shearing
worsted and other textile fabrics, in such a manner that the cropping operation is

page_text: more perfectly performed, uneven wear in the bearings or bushes of the said cutter
is prevented, and the fixed horizontal knife is kept perfectly smooth throughout
its length.
In order that our invention may be clearly understood, we will proceed to
describe same with reference to the accompanying drawing, in which similar letters
of reference refer to like parts in both figures.
Figure 1 is an end view and Figure 2 is a front view, of a portion of a cropping
machine with our invention applied thereto.
A is the framework of the machine, and B is the revolving cutter, which is
mounted on the shaft C and carried in bearings D. E is a flanged disc which is
mounted on the shaft C, and F is a double ended lever fulcrumed on a bracket G
connected with the framework A. One end of the lever F works in the groove in
the disc E, and the opposite arm of the said lever F works in a cam way H
situated in the cam K, which latter is mounted on the drawing roller shaft L.
On the machine being set in motion, the rotation of the cam K causes the lever F
to be rocked on its fulcrum on the bracket G, and the upper end of the lever F
thereby rocks the disc E, which being attached to the shaft C reciprocates same
in its bearings D, thereby reciprocating the revolving cutter B. This combined
revolving and reciprocating movement of the cutter B, crops the material under
operation in a most effectual and efficient manner, whilst at the same time the
steady backward and forward movement of the cutter shaft C prevents uneven
wear of the bushes or bearings D, and grooving of the fixed horizontal knife M
is obviated by the constantly varying position of the revolving cutter B.
The reciprocating action of the revolving cutter B, causes same to give a cross
cutting effect to the goods under treatment, thus giving a smarter and cleaner
appearance to the fabric, which is of the greatest importance in close cut worsted
goods.
Although we have described and shewn certain mechanical parts whereby the
revolving cutter B may have a reciprocating movement imparted thereto, we would
have it clearly understood that we do not confine ourselves to such particular
means, as any other suitable mechanism might equally well be employed for
reciprocating such cutter.
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 we
claim is
1. In machinery for cropping or shearing worsted and other textile fabrics,
the reciprocating of the revolving cutter, substantially as and for the purposes
set forth.
2. In machinery for cropping or shearing worsted and other textile fabrics, the
combination of the shaft C, flanged disc E, lever F, and cam K, substantially as
and for the purposes set forth.
3. In machinery for cropping and shearing worsted and other textile fabrics,
the general arrangement, construction and combination of the various parts forming
our invention, substantially as and for the purposes set forth.
