We JOHN FARRAN of 17, Trafalgar Square, Brooks' Bar, Manchester, in the
County of Lancaster, Mechanician, and FREDERICK CHARLES CRAWFORD of 70 New
Lane, Barton-upon-Irwell in the County of Lancaster, Fustian Cutter, do hereby
declare the nature of this invention to be as follows:-
Our invention relates to such of the machines for "cutting,"
cropping" the
"
"
८८
shearing" or
face" ог pile of "pile fabrics" and other fabrics, as are
provided with revolving "spiral" cutters or other revolving cutters.
We shall hereinafter refer to the revolving "spiral" cutter or other revolving
cutter of each machine as the revolving cutter.
Beneath the revolving cutter and parallel to the axis thereof we place a bar of
triangular or other suitable form, which bar is secured at its ends to the end-framings
or other suitable parts of the machine. The axle of the revolving cutter is at each
end carried by and free to be rotated in bearings formed upon or in a lever jointed
to an arm capable of being turned upon a stud or pin mounted in or upon a bracket
secured to or formed upon the end-framing or other suitable part of the machine.
The said lever, arm and bracket are provided with set screws by means of which the
revolving cutter can be adjusted in position horizontally and vertically. The arm
before mentioned is guided vertically by a bracket secured to the end-framing or
other suitable part of the machine. To the end-framings or to other suitable parts
of the machine we secure brackets which support so that they are capable of revolving
therein, the ends of a shaft provided with arms or levers which by means of con-
necting rods are each connected to the arms by which the revolving cutter is sup-
ported. The shaft before mentioned is provided with a hand-wheel by means of which
the revolving cutter may be quickly raised clear of the "cloth or fabric being
operated upon and may be retained clear of such fabric by means of a ratchet wheel
and pawl. We support the "ledger blade" at its ends in brackets capable of being
slidden upon other brackets secured to the end-frames or other suitable parts of the
machine. The brackets at the opposite ends of the "ledger blade" we provide with
screws by which the "ledger blade" may be adjusted so as to be nearer to or farther
from the above mentioned bar of a triangular or other suitable form.
"
The fabric or "cloth" to be "cut," "shorn" or "cropped" is passed over a roller;
then over the bar above mentioned of a triangular or other suitable form and then
over another roller. The said rollers are provided with needles, pins, or spikes. We
cause the surface of one of the said rollers to move somewhat more quickly than the
surface of the other roller so that the fabric or "cloth" will be kept in a state of
tension. In order that the "cloth" or fabric may after being operated upon by the
revolving cutter, be disengaged from the second roller provided with needles, pins, or
"
cloth or
spikes we employ a revolving brush so placed that it will cause the said
fabric to be disengaged from the needles, pins, or spikes of the said roller. We impart
rotary motion to the said revolving brush in any suitable manner.
We impart
rotary motion to the rollers above mentioned by means of suitable gearing and a
suitable clutch by means of which the said gearing may be connected to or discon-
nected from a rotating shaft which receives rotary motion in any convenient manner.
We also employ a rod extending across the machine and connected to a lever provided
with suitable jaws by means of which when the said rod is moved in a suitable
direction a portion of the clutch above mentioned may be connected to or disconnected
from the rotating shaft and we thus enable the rollers above mentioned to be
started and stopped as required.

page_text: cutter 29, be disengaged from the pins, needles, or spikes of the roller 59, we employ
a. revolving brush 60, so placed that it will cause the said cloth or fabric 1. to be
disengaged from the needles, pins, or spikes of the roller 59.
"
The revolving brush 60 receives rotary motion from the roller 58 by means of the
wheels 61, 62, and 63. The rollers 58, 59 and the revolving brush 60 are mounted
in bearings formed in or carried by the end-framings of the machine. Carried by
and capable of being rotated in bearings formed in the end-framings of the machine
is a shaft 64, which by means of a pulley 64", receives rotary motion in any
suitable manner. Fast upon the shaft 64 is a pulley 64, which, by means of a
band or cord 64° imparts rotary motion to the revolving cutter 29. The band or
cord 64 passes over a tightening pulley 64. Mounted upon the shaft 64 is a
wheel 65. The wheel 65 at times imparts rotary motion to the roller 59 by means
of the train of wheels 66, 67, 68, 69, 70, 71 and the wheel 72 fast upon the axle
of the roller 59. Gearing into the wheel 72 is a carrier wheel 73, which, being
rotated, imparts rotary motion to a wheel 74 gearing into a wheel 75 fast upon the
axle of the roller 58. The wheel 72 is of less diameter than the wheel 75, so that
the "cloth or fabric I. passing over the rollers 58, 59 will be kept in a state of
tension. In some cases, instead of causing a tension on the cloth or "fabric" I.
by rotating the roller 59 at a greater speed than the roller 58 by means of
wheels such as 61, 62, 63, we retard the rotation of the roller 58 by means of
a brake, for which purpose we secure upon the axle of the roller 58 a grooved
pulley 58, around which passes a rope or strap 58b, secured at one end to a stud 58°,
secured to the end-frame 27. We put a tension upon the rope or strap 58b by
means of a spring 58d or by means of a weight. The pulley 58%, rope or strap 585,
stud 50, and spring 58d are only indicated in dotted lines in Figs. 1 and 2.
Secured to the end-framings 27, 27 are brackets which support, so that it is capable
of being slidden longitudinally therein, a rod 76 extending across the machine.
One end of the rod 76 is jointed to one end of a lever 77, carried by and capable
of turning upon a stud 78. The end 77 of the lever 77 is formed with jaws, the
ends of which pass into a groove formed in a collar 65" capable of being slidden
longitudinally upon the shaft 64. Formed upon the collar 65 is one part 65 of
a clutch, which may at times engage with or be disengaged from another part 65°
fast with the wheel 65, which is loose upon the shaft 64. The part 65 of the
clutch receives rotary motion from the shaft 64 by means of a key and groove, so
that the collar 65 is at liberty to be slidden longitudinally upon the shaft 64 while
being caused to rotate. By the rod 76 being moved in the direction indicated by
the arrow J. the part 65 of the clutch may be removed from the part 65°, and
thus the rotation of the rollers 58, 59 may be stopped. When it is desired to
again start the rollers 58, 59 the rod 76 is moved in a direction opposite to that
indicated by the arrow J. and the part 65° of the clutch is thus caused to engage
with the part 65º.
"
In some cases we cause the "cloth" or fabric I. during its passage to the first
of the rollers 58, 59 provided with needles, pins, or spikes, to pass over a
"roller
temple' or a bar or plate provided with grooves and ridges, by passing over which
"roller temple," or bar or plate the cloth or fabric I. will be caused to be free from
folds or creases before passing upon the said roller provided with needles, pins, or
spikes.
The arrangements above described enable the revolving cutter 29 and "ledger
blade 26 to be readily and accurately adjusted into proper working position, and
cause the "cloth "
or fabric to be readily drawn forward beneath; the revolving
cutter 29, or stopped, as may be 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 we
claim is
