Improvements in the Method of and Apparatus for Outting the
Float Threads in Tulles, Nets, Laces, Embroideries, and similar
Fabrics.
I, WILLIAM EDWIN HEYS, of 70 Market Street Manchester in the County of
Lancaster, Patent Agent, do hereby declare the nature of this invention to be as
follows:
Tulles, nets, laces embroidery and similar fabrics having floating threads such as
those which connect or bind the different paitt of flowers, embroideries, and devices,
are submitted to a final manipulation which consists in removing the threads by hand
after the fabric is finished.
This Invention relates to a method of and means for removing the threads by
mechanical devices. The fabric to be operated upon being stretched on the fixed
frame of the finishing apparatus, the cutting device which is the subject of this
Invention is passed under the floating threads which are then severed thereby.
The cutting device consists of a series of blades each of which is terminated by a
small ball or lenticular part which facilitates its introduction below the threads to
be cut. The blades are mounted parallel with each other and similarly to the
teeth of a rake and alternately with metallic stems which have for their object to
afford support for the thread upon the sharp edge of the blade. By the intro-
duction of the blades below the floating threads, the threaus are severed, and after
this operation the fabric is carried to a shearing or similar machine by means of
which the severed ends may be removed.
The blades hereinbefore referred to may be replaced by scissors or similar cutting
device..

Improvements in the Method of and Apparatus for Cutting the
Float Threads in Tulles, Nets, Laces, Embroideries, and similar
Fabrics.
I, WILLIAM EDWIN HEYS of 70 Market Street Manchester in the County of
Lancaster, Patent Agent, 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 :-
Tulles nets laces embroideries and similar fabrics having floating threads such
as those which connect or bind the different parts of flowers, embroideries, and
other devices, are submitted to a final manipulation which consists in removing the
superfluous threads by hand after the fabric is finished.
This Invention relates to a method of and means for removing the threads by
mechanical means. The fabric to be operated upon being stretched on the fixed
frame of the finishing apparatus, the cutting device which is the subject of this
Invention is passed under the float threads which are then severed thereby. The
cutting device consists of a series of blades each of which is terminated by a small
ball or lenticular part which facilitates its introduction below the threads to be cut.
The blades are mounted parallel with each other and similarly to the teeth of a
rake, alternately with metallic stems which have for their object to afford support

below the float threads, the threads are severed, and after this operation the fabric
is carried to a shearing or similar machine by means of which the severed ends may
be removed.
The blades herein before referred to may be replaced by scissors or similar cutting
devices.
And in order that my said Invention may be more readily understood and carried
into effect I have appended hereto a sheet of drawings which I will now proceed
to describe.

simplest form of the apparatus in plan and side view
the cutting blades upon the end of each of which there is
enlarged part B Between each of the cutting blades
parallel metallic stem D for the herein before described
Fig. 2 represents in side view and Fig. 3 in plan a modified form of the
cutting apparatus. L L are the knives or cutting blades which have lenticular
terminations and are mounted parallel with each other in a metallic frame () provided
with the handle P. The number of blades and their distances apart may vary and
will be governed by the character of the work to be performed by them. On the
opposite end of the frame C and precisely opposite each of the blades there is fixed a
flat spring R which terminates in a groove or sit lenticular part r. The point of
each blade L enters the slit in the corresponding spring and the blades and springs
are respectively so mounted in the frame that their lenticular parts are in a plane
inferior to the plane of the frame as indicated in the Figures The nature of
the spring compels the blade to be in constant contact therewith.
In using the apparatus the operative slides the frame by means of the handle so
that the parts come under the threads to be cut, and then draws the frame back-
wards towards herself. By this backward motion the threads are brought between
the springs and the blades by which they are severed.
The blades instead of being fixed upon the frame C may be mounted upon a
spindle fixed at a slight elevation above the frame and capable of turning in
bearings on the sides of the frame. The spindle is arranged to turn under the
influence of a spiral spring which tends constantly to press the ends of the blades
towards the lenticular parts.
The severed ends of the cut float threads are removed by a cropping or shearing
machine as hereinbefore described.
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.
(1) An apparatus for cutting float threads constructed and arranged substantially
as hereinbefore described and as illustrated by Fig. 1 of the accompanying
drawings.
(2) An apparatus for cutting float threads constructed and arranged substantially
as hereinbefore described and as illustrated by Figs. 2 and 3 of the accompanying
drawings.
(3) The hereinbefore described method of cutting float threads on tulles, nets,
laces, embroideries, and other similar fabrics and which consists in introducing below
the float threads a blade or blades having on the end of each blade a ball enlargement
or lenticular part, and in severing the threads by a further motion of the blade or
blades, substantially as herein before described.
