PROVISIONAL SPECIFICATION.
Improvements in or connected with Machines for Cutting Fustians,
Cords, and Velvets.
We, JAMES SCHOFIELD, of the Brookfield Mill, Littleborough, in the County
of Lancaster, Fustian Manufacturer, and RALPH DODD, of 89, Victoria Street,
Littleborough, aforesaid, Foreman Cutter, do hereby declare the nature of this
invention to be as follows:
Our said invention relates to improvements in machines which are used to cut
the races of fabrics so as to form cords and velvets as is well understood.
In the type of machine to which our invention relates the cutting knife and
the guide therefor are carried by a bracket which is mounted so as to be capable
of oscillating on a pivot. During the cutting of a race if the knife meets with
any obstruction it is turned down, the bracket being thus oscillated and this
movement of the pivot of the bracket is utilized to bring into action a stop
motion which stops the machine. It is found in practice however that when an
obstruction is met with the knife when depressed bursts the fabric before it can
be stopped causing damage to the cloth which it is impossible to neatly repair.
The object of our invention is to overcome this defect.
This we effect by arranging below the guide bracket a suitable spring in
contact with the fabric so that when the knife is depressed and the stop motion
is set into action the spring is compressed and the force of the impact between
the guide and cloth relieved.
Thus instead of bursting the fabric as before, the fabric is only slightly
perforated, which perforation can be easily repaired without leaving any per-
ceptible flaw.
A convenient method of carrying our invention into effect is as follows. The
oscillating guide bracket is widened at the top to form a bearing for a flat spring
secured to the bracket. The flat spring is formed with a central slot for the
passage of the knife and guide, and is curled under the bracket to come into
contact with the fabric. The shape and arrangement of spring may however
be varied if desired without departing from the spirit of our invention.
We find that in addition to preventing the cutter from bursting the fabric,
the spring operates to greatly improve the general working of the knife, by
regulating the oscillations and directing the guide, also causing less frequent
"fettling" by the attendant.

We, JAMES SCHOFIELD, of the Brookfield Mill, Littleborough, in the County
of Lancaster, Fustian Manufacturer, and RALPII DODD, of 89, Victoria Street,
Littleborough, aforesaid, Foreman 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 and accompanying
drawings:-
Our said invention relates to improvements in machines which are used to cut
the races of fabrics so as to form cords and velvets as is well understood.
In the type of machine to which our invention relates the cutting knife is
carried by a bracket which is mounted so as to be capable of oscillating on a
pivot.
During the cutting of a race if the knife meets with any obstruction it is
turned down, the bracket being thus oscillated and this movement of the pivot
of the bracket is utilized to bring into action a stop motion which stops the
machine. It is found in practice however that when an obstruction is met with
the knife when depressed bursts the fabric before it can be stopped causing
damage to the cloth which it is impossible to neatly repair.
The object of our invention is to overcome this defect.
This we effect by arranging below the knife and bracket a suitable spring in
contact with the fabric so that when the knife is depressed and the stop motion
is set into action the spring is compressed and the force of the impact between
the knife and cloth relieved.
Thus instead of bursting the fabric as before, the fabric is only slightly
perforated, which perforation can be easily repaired without leaving any per-
ceptible flaw.
The accompanying sheet of drawings clearly illustrates our invention.
Fig. 1 shows in elevation so much of a machine for cutting pile fabrics as is
necessary to explain our invention.
Fig. 2 is a plan view of same, and
Fig. 3 a detail view.
In the drawings the knife carrier a provided with an adjustable guide b carries
a bracket c secured to the carriera by means of screws c¹. The bracket c forms
a bearing for a pivotted bracket d capable of oscillating upon a pivot e in the
bracket c. The bracket d is provided with a pendent arm d¹ in the lower end
of which is mounted the trunnion e¹ of the knife bracket f to which is secured
the knife g. The knife bracket f is capable of rocking on its trunnion e¹ in the
pendent arm d. It must be understood that the foregoing arrangement is the
usual construction and forms no part of our invention.
For the purposes of our invention we now form the knife bracket f to accommo-
date a flat spring h. The flat spring his slipped between guides f¹ on the
bracket from which it is readily removable. The spring may however be
secured to the knife bracket by soldering or by means of screws or rivets, or the
spring may be secured to any other adjoining bracket or portion of the machine
in connection with the bracket d. The spring his formed with a central slot h¹
for the passage of the knife g shown more clearly in the end view Fig. 3 and is
curled under the knife and bracket to come into contact with the fabric i.
The shape and position of the spring may however be varied if desired without
departing from the spirit of our invention.

page_text: In operation should the fabric i, which travels in the direction of the arrow,
present any obstruction to the knife 9 the knife is turned downwards on its
pivot e¹ the bracket d oscillated on the pivot e so as to actuate the stop rod j in
the usual manner. The spring his thus compressed relieving the force of the
impact between the knife and cloth or between the swinging bracket d and the
cloth as arranged. A slight perforation in the fabric only results instead of
a burst which perforation is easily repaired.
We find that in addition to preventing the cutter from bursting the fabric,
the spring operates to greatly improve the general working of the knife, by
regulating the oscillations and directing the knife, also causing less frequent
fettling" by the attendant.
By bending or curling the curved ends of the spring more or less the angle
at which the knife is presented can be varied to a certain extent.

Further the spring resting on the fabric prevents any tendency to lateral
movement of the knife.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is:-
In machines of the indicated nature for cutting the races of fabrics to form
cords and velvets, the provision of a spring arranged in conjunction with the
cutting knife in the manner, for the purposes and substantially as described
and illustrated.
