PROVISIONAL SPECIFICATION.
Improvements applicable to Cutting, Cropping, and Clipping
Machines for Textile Fabrics.
I, RICHMOND INGLIS COCHRANE of the firm of J. R. Cochrane & Company of
47 Waddell Street, Glasgow in the County of Lanark, North Britain, Manufacturers,.
do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in cutting, cropping, or clipping machines.
for ornamental textile fabrics and is applicable to all kinds of such machines at
present in use,
and my said improvements have for their object to construct the said
cutting, cropping and clipping machines that they will work with less power, less
dust, less noise and less vibration as well as do the cutting work more efficiently
than before whether it be lappet pile or other fabric.
In carrying out my said invention I dispense with the use of the primary
reciprocating knife or cutter (and with or without the rotating spiral cutter) and in
lieu thereof I employ an endless steel band having a cutting edge formed on
one edge.
My improvements may also if desired be applied to machines for cutting pile
fabrics by cutting the pile in two so as to have two separate pile cloths which have
been woven double, (although face to face as one), the pile warp going from one
cloth to the other and which process is done by a reciprocating knife at present.
Dated this 5th day of July 1892.

COMPLETE SPECIFICATION.
Improvements applicable to Cutting, Cropping, and Clipping
Machines for Textile Fabrics.
I, RICHMOND INGLIS COCHRANE, of the firm of J. R. Cochrane and Company of
47 Waddell Street, Glasgow, in the County of Lanark, North Britain, Manufacturers,.
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 relates to improvements in cutting, cropping and clipping machines.
for cutting and removing the connecting or loose threads of lappet patterns or other
similar ornamental fabrics and is applicable to all kinds of such machines and my
said improvements have for their object to construct the said cutting, cropping or
clipping machines so that they require less driving power; work with less dust,.
noise and vibration, and do the cutting work more efficiently than hitherto whether
it be lappet, pile or other fabric that is being operated upon.
In carrying out my said invention I dispense with the use of the primary
reciprocating knife or cutter hitherto in use (and with or without the rotating spiral
cutter) and in lieu thereof I employ an endless steel band having a cutting edge.
formed on one edge.
Figure 1 is a part front elevation of the machine constructed in accordance with
my said invention and Figure 2 is an end elevation of the same.
The band knife A is led across the machine under the feelers or fingers B (in the
same manner as the reciprocating knife hitherto used) and around the pulleys C
mounted in brackets D, D' which are supported by the main standards or cheeks E
of the machine. The one bracket D is made adjustable as shown so that the tension

page_text: of the band knife may be regulated as desired. The pulleys C are shown mounted
at the sides of the machine so as to lead the return portion of the band knife
through the machine. The band knife is driven at a high speed by means of the
pulleys C and G and the band F or by other gearing from the main or other driving
shaft H of the machine.
The pulleys C may be varied in size and may be differently mounted according
to circumstances for example they might be mounted above the machine about the
same level as the pressing roller X or they might be mounted as large pullies at the
side of the machine, so that the return portion of the band knife either passes in
the former case above the machine overhead, or in the latter case low down through
or below the machine.
My improvements may also if desired be applied to machines for cutting pile
fabrics which have been woven double, that is to say, where two cloths are woven
face to face with the pile warp passing from one cloth to the other, the said cutting
of the fabrics into two separate pile cloths being effected by my band-knife in lieu
of by the reciprocating knife as heretofore.
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 machines for cutting, clipping and cropping textile fabrics, the employment of
an endless band-knife, substantially as and for the purposes hereinbefore described
and shown in the accompanying drawings.
