PROVISIONAL SPECIFICATION.
Improvements in Cutting the Pile of Weft Pile Fabrics.
I, GEORGE ROGER, of 40 Padgate Lane, Warrington, Master Fustian Cutter,
do hereby declare the nature of this invention to be as follows:-
:-
The improvements relate to the cutting of weft pile fabrics, and are more
particularly applicable to cutting on what is known as the long run, although they
may be adapted to the short frame if requisite, and have for object greater facility
in connection with such cutting.
To accomplish this and to effect my improvements, I mount in any convenient
manner at each end of a stretched piece of cloth in a cutting frame, a drum or
pulley, either vertically, horizontally, or at an angle, around which pulleys I cause
to pass an endless cord, wire or band-or it may be a light chain gearing-which
cord, wire or band stretches above the surface of the fabric, in sufficiently close
proximity thereto.
To this cord, wire or band I attach at two points a light frame, by means of
which the cutting knife is actuated in its travel in such manner that, as the band is
moved, the knife is pulled or pushed along in the race of the fabric.
Attached to, connected with, or forming part of each of the pulleys aforesaid
may be arranged a second pulley, preferably concentric with the first, and of
smaller diameter, around which smaller pulleys a second cord, wire or band is
caused to pass.
Thus, as the operator moves the last named band, the pulleys are revolved, and
the band passing over the larger pulleys is moved to a greater distance than the
actuating band, whereby a distance of race is cut, at one operation, which may
greatly exceed the travel of the operator; or the operator may remain stationary,
moving the cord only within arms length, and yet cause the knife to travel a
considerable distance."
Or in lieu of this second set of pulleys and bands, a handle may be attached to
one of the first named pulleys and thereby the knife may be carried forward by the
simple turning of such handle. In like manner, a handle may be attached to one
of the secondary pulleys above named, and the actuation effected thereby in an
analogous manner.
At the same time, the operator can readily become sensibly aware of any varying
action given to the knife arising from penetration of the fabric, or other cause, by
means of a screw or other tension apparatus for stretching apart the pulleys to the
proper degree requisite for the purpose.
Variations in detail, such as the dimensions and number of the pulleys, and
method of mounting the same with or without a turning handle; the manner of
attaching the knife carrier to the band, and in the mode of applying the tension to
such band or bands, together with the design and material of the various parts, may
be made without departing from the peculiar character of the invention.
Dated this 15th day of October 1895.

1, GEORGE ROGER, of 40 Padgate Lane, Warrington, Master Fustian Cutter,
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 improvements relate to the cutting of weft pile fabrics, and are more
particularly applicable to cutting on what is known as the long run, although they
may be adapted to the short fraine if requisite, and have for object greater facility
in connection with such cutting.
To accomplish this and to effect my improvements, 1 mount in any convenient
manner at each end of a stretched piece of cloth in a cutting frame, a drum or
pulley, either vertically, horizontally or at an angle, around which pulleys I cause
to pass an endless cond, wire or band-or it may be a light chain gearing-which
cord, wire or band stretches above the surface of the fabric in sufficiently close
proximity thereto.
To this cord, wire or band I attach at two points a light frame, by means of
which the cutting knife is actunted in its travel in such manner that, as the band is
moved, the knife is pulled or pushed along in the race of the fabric.
Attached to, connected with, or forming part of each of the pulleys aforesaid
may be arranged a second pulley preferably concentric with the first, and of
smaller diameter around which smaller pulleys a second cord, wire or band is
caused to pass, in such manner that, as the operator moves the last named band,
the pulleys are revolved, and the band passing over the larger pulleys is moved to
a greater distance than the actuating band, whereby a distance of race is cut at
one operation, which may greatly exceed the travel of the operator;
or the
operator may remain stationary, moving the cord only within arms length, and yet
cause the knife to travel a considerable distance.
Or in lieu of this second set of pulleys and bands, a handle may be attached to
one of the first named pulleys, and thereby the knife may be carried forward by
the simple turning of such handle. In like manner, a handle may be attached to
one of the secondary pulleys above named, and the actuation effected thereby in an
analogous manner.
At the same time, the operator can readily becomo sensibly aware of any varying
action given to the knife arising from penetration of the fabric, or other cause, by
means of a screw or other tension apparatus for stretching apart the pulleys to the
proper degree requisite for the purpose.
But that the improvements may be better understood, I will with the aid of the
accompanying drawings, proceed more fully to describe means employed by me.
DESCRIPTION OF DRAWINGS.
Fig. 1 shows an elevation partly in section, and Fig. 2 a plan view of apparatus
árranged in accordance with one form of my invention, at the operating end of the
stretched piece of cloth; while Fig. 3 shows an elevation partly in section, and
Fig. 4a plan view of apparatus arranged in accordance with a like form of my
invention, at the opposite end of the strained piece of cloth.
The same letters indicate corresponding parts wherever they occur.
a is a portion of the framing carrying the tightening rollers & for the purpose of
stretching the cloth to be cut, as will readily be understood, and all details of which
are omitted for the sake of clearness. care the pieces of cloth, although only one
may be operated upon at once; but it is practicable to operate two as shown,
which may be arranged either to averlan auch other in their width

page_text: arranged clear of each other side by side. is a portion of the framing carrying
the special apparatus to be described, the other end being supported by the
ordinary framing a, although, if preferred, the framing may be designed to carry
the apparatus independently.
e shows a weft pile cutting knife, which is carried forward by means of the
carrier actuated by the band or cord y, which passes round the pulley /, to which
is attached the smaller pulley, and which is driven by the band or cord j passing
round the third pulley k, which is operated by the handle 1, as will be readily
understood. The cord or band g traverses the length of the strained portion of
cloth and round the pulley m, which is mounted on the stud n, attached to the
sliding plate or frame o. In similar manner the pulley is mounted on the slide p,
which carries with it the pulley k, with its handle 1, by means of the projection 7,
the end of which rests and slides on the bar forming part of or attached to the
frame a.
The slide is caused to synchronize with the slide o by means of the cord.or
bands, passing from its attachment of the one slide to the attachment of the other
slide, round the pulleys t, u, and v. In addition, counterbalancing cords w and w
are shown in Figs. 2 and 4, passing over pulleys, and to the ends of which weights
are attached, but which are omitted in the other views for the sake of clearness.
Any suitable means may be employed for adjusting the length of this cord, for the
purpose of keeping the slides in their proper relative positions, and in Fig. 2 a
ratchet wheel, and pawl a, is shown on the shaft or drum, upon which a cord,
whose other end is fixed as at y, is wound at intervals by such ratchet wheel and
pawl, but the slide may be actuated by a worm or screw or other mechanical
equivalent for this purpose, if desired.
To keep the band of the requisite degree of tension, the screw extension is
provided, whereby the pulleys and are forced apart or drawn together as
desired.
In operation, the knife is set in to the "race" in the ordinary manner, when the
handle is turned and the knife carrier travels with the knife to the opposite end,
and is brought back by reversing the motion of the handle. The knife may be
attached loosely to the carrier by means of a cord and hook, or other convenient
arrangement to ensure the same being brought back to the operator. When two
pieces of cloth are strained as shown, a knife carrier is provided to both halves of
the cord in such manner that one goes forward as the other returns.
By means of the adjustment of tension of the actuating cord j, great delicacy of
operation may be obtained, so as to enable the operator to readily feel any variation
in the resistance to the force required to actuate the knife. Only just sufficient
tension may be given to the actuating cord to enable it to propel the knife when
cutting a single "race," so that in the event of the knife meeting with any
obstruction or more than normal resistance to its travel, the actuating cord will
slip on the pulley, and the knife will then cease to travel, so that if the kuife turns
into the "slip" or double race, or makes a hole in the cloth, it stops in its progress,
and thus avoids further damage to the cloth.
In lieu of the handle pulley, a pulley without a handle, as already described, may
be employed, and the operator would in that case actuate the apparatus by pulling
the cord to and fro.
As a variation the pulley moved by the operator may be made to drive the
pulley which carries the travelling cord by frictional contact, or by means of a
brush wheel, adjusted by a screw or tension apparatus as before mentioned, so as
to enable the operator to feel any varying resistance to the knife. Or in lieu of a
handle, a foot treadle and crank may be employed, or a driving pulley and strap
may be substituted when steam or other power is desired, as will be readily
understood.
Also when only one knife is employed, the pulleys carrying the band g may be
mounted in other positions than the horizontal as shown, and the design of the parts
and precise mode of actuating and connecting the same, may be made, together

page_text: with other variations in detail, without departing from the peculiar character of the
invention.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I would have it understood
that I do not claim the employment of a running band and travelling knife per se,
but what I claim is :-
:-
1. In apparatus for cutting weft pile fabrics by means of a travelling knife or
knives actuated by running cord or band, the combination of the pulleys and m
carrying the band or cord, with the pulleys and mounted in connection, and
with the band actuating the cutting knife, for the purpose and in manner substan-
tially as herein shown ñud described.
2. In apparatus for cutting weft pile fabrics by means of a travelling knife or
knives actuated by a running cord or band, the combination of the connecting
cords, and pulleys t, u, v, with the sliding plates p, and o, whereby the two pulleys
may be moved synchroniously across the piece by means of the ratchet .r, and
paul 2, or other traversing motion, for the purpose and in manner substantially as
herein shown and described.
3. In apparatus for cutting weft pile fabrics by means of a travelling knife or
knives netunted by a running cord or band, the combination of a tension screw
or other adjustment, for regulating the operating power of the travelling cord
upon the knife, by tightening or otherwise the secondary driving cord or band j,
for the purpose and in manner substantially as herein shown and described.
4. In apparatus for cutting weft pile fabrics by means of a travelling knife or
knives actuated by a running cord or band, the special combination of parts
arranged as illustrated in the drawings, or their mechanical equivalents, for the
specific purpose and in manner as herein shown and described.
