Improvements in Knives for Cutting the Pile on Fustians, Velvets,
Velveteens, and similar Fabrics.
I, CHARLES BROUGH of Shakspere Street, Ardwick, Manchester, in the
County of Lancaster, Velvet Manufacturer, do hereby declare the nature of this
invention to be as follows:-
In the cutting of fustians it has hitherto been usual to cut with a single bladed
knife and although attempts have been made to make such knives with two or more
blades I do not consider that any such attempts have been successful and have
designed this invention with the object of providing a knife that will cut two or
more rows or races at the same time.
The invention consists essentially in constructing a fustian cutting knife with two
or more blades so shaped that the cutting part of each shall lie in approximately
the same straight line the point of one reaching a few inches behind that of
another so that two or three rows can be cut at one stroke or operation without
one interfering with the working or action of the other.
In carrying the invention into effect for a hand knife I fit two or more blades-
preferably either two or three into a handle somewhat similar to that at present in
use but made sufficiently wide at the fore end to receive the two or three blades.
One, two, or all of the blades are cranked or bent in their length so that the axis
of the cutting part does not correspond with that of the upper end of the blade by
this means two or three blades can be fitted into one handle and the cutting part of
the blades all lie in the same line--or as near to the same as required-the point of
one being at a distance of from about four to six inches behind that in front of it
and clear of the other part of the blade.
For a three bladed knife I prefer to place the blades side by side in the handle
and one may be straight while the other two are cranked so as to bring the points
to the proper position or all three may be cranked if found more easy of
adjustment.
For a two bladed knife the blades may be set either side by side or one above
the other and so cranked or bent as to give the desired result. Where one blade
is placed above the other the upper one will be cranked preferably downwards and
the lower one may be straight or cranked a little to one side and where one is
placed beside the other one may be straight and the other cranked side ways.
The socket of the handle into which the ends of the blades fit is made so that
the blades may be readily removed and replaced in position and the end of the
blade is made with a T-head or ball-head or other device to correspond with the
socket in the handle into which it fits.

Improvements in Knives for Cutting the Pile on Fustians, Velvets,
Velveteens, and similar Fabrics.
I, CHARLES BROUGH, of Shak pere Street, Ardwick, Manchester, in the
County of Lancaster, Velvet Manufacturer, 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 :-
In the cutting of fustians and similar fabrics it has hitherto been usual to cut
with a single bladed knife and although attempts have been made to make such
knives with two or more blades I do not consider that any such attempts have been.
successful and have designed this invention with the object of providing a knife
whereby two or more rows or races may be cut at the same time.
The invention consists essentially in constructing a fustian cutting knife with two
or more blades so shaped that the cutting part of each shall lie in approximately
the same straight line the point of one reaching a few inches behind that of another
so that two or three races can be cut at one stroke or operation without one inter-
fering with the working or action of the other.
It will be fully described with reference to the accompanying drawings, two
arrangements of double bladed hand knives being shown as examples.
Fig. 1, side elevation showing the two blades placed in the same vertical plane
one above the other.
Fig. 2, plan showing the two blades placed in the same horizontal plane one
beside the other.
The blades A and B which form the knife are fitted into a handle or socket C.
The blade A is straight and similar to the blade of a single bladed knife such as is
at present in use. The blade B is cranked bent or curved in its length so that the
axis of the cutting part does not coincide with that of the upper end of the blade
by this means two or three blades can be fitted into one handle and the cutting
part of the blades all lie in adjoining races or as nearly in the same line as required.
The straight blade A is preferably shorter than the bent blade B the point of the
blade A being at a distance of from about three to six inches behind that of the
blade B and clear of the other part of the blade.
At present I prefer to use two blades in one knife one blade placed above the
other as in Fig. 1 each blade is fitted into a handle or socket C. The straight
blade A is placed beneath the bent blade B and the handle of the latter lies on top
of that of the other, the two being grasped in the hand of the operator together.
When the blades are placed side by side as in Fig. 2 the socket or handle C into
which the ends of the blades fit may be made single and so that the blades may be
readily removed and replaced in position and the end of the blade may if desired
be made with a T-head or ball-head or other device to fit a corresponding socket
in the handle into which it fits.
For a three bladed knife I prefer to place the blades side by side in the handle
and one may be straight while the other two are cranked so as to bring the points
to the proper position or all three may be cranked if found more easy of
adjustment.
When in operation the bent blade is always the first to commence work with the
straight blade working in the adjoining race. The cutting edges of both blades
work on the same level the straight blade at the distance of a few inches behind
the bent one and not abreast of it. In a three bladed knife where all are bent
except one each succeeding blade is bent with a greater bend than its predecessor.
In this case the blade with the greatest bend commences work first, the one with
the next greatest bend second in the adjoining race and so on, the straight one
being last.
The advantage which this invention effects is that it enables a fustian cutter to

page_text: work with two or more fustian-cutting blades simultaneously and in combination
and to make them essentially into one knife cutting adjoining races in the cloth,
whereas the knife hitherto in use has been a one-bladed knife.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what
I claim is
1. A knife for cutting fustians and similar fabrics having one straight blade and
one or more bent blades so that the cutting parts thereof may lie when in operation
in adjoining races one a few inches behind the other substantially as described.
2. A blade for a fustian cutting knife cranked bent or curved in its length so
that the axis of the cutting part does not coincide with that of the upper end
substantially as and for the purpose described.
