PROVISIONAL SPECIFICATION:
Improved Machinery for Drawing Waste Silk, Wool, and other
Fibres.
I FREDERIC TEr Weele of 21 Boulevard Poissonnierė, Paris in the Republic
of France, Engineer, do hereby declare the nature of this invention to be as
follows:-
The object of this invention is to effect the even drawing of short fibres more
effectually than heretofore.
To this end, I provide for every gill or card roller in the machine, whether two,
three, or more are used; a pair of retaining rollers, which rollers will, while feeding
forward the fibres, ensure their entering well between the pins of the gill or card
roller, thus enabling the fibres to offer a proper resistance to the action of the
drawing rollers. The fibres supplied to the machine enter first between a pair of
ordinary feed rolls. They next pass between a pair of retaining rollers, which
deliver the fibre to the first gill or card roller.
This roller delivers the fibre to a pair of drawing rollers, which serve also as
feed rollers to a second gill or card roller. From this roller, the fibres pass to a
second pair of drawing rollers, whence they are delivered out of the machine, or,
if desired, the drawing action may be continued by means of an additional gill or
card roller and drawing rollers corresponding thereto, the drawing rollers of the
second gill roller acting in such case as retaining rollers.
The gill rollers I mount somewhat above the line of bite of the retaining and
drawing rollers, and-by this means ensure the fibres bedding well into the pins of
the rotating gill or card rollers. The surface speed of the various rollers will be
adjusted to suit the amount of "drawing" required.
Dated this 2nd day of September 1892.

.
I FREDERIC TER WEELE of 21 Boulevard Poissonnierè, Paris in the Republic
of France, Engineer, 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 object of this invention is to provide for the even drawing of short fibres
more effectually than heretofore.
.
To this end, I apply to every gill or card roller in the machine (whether two,
three, or more are used) a pair of retaining rollers, which rollers will, while feeding
forward the fibres, ensure their entering well between the pins of the gill or card
roller, thus enabling the fibres to offer a proper resistance to the action of the
drawing rollers. The fibres supplied to the machine enter first between a pair of
ordinary feed rolls. They next pass between a pair of retaining rollers, which
deliver the fibre to the first gill or card roller.
This roller delivers the fibre to a pair of drawing rollers, which serve also as
feed rollers to a second gill or card roller. From this roller the fibres pass to a
second pair of drawing rollers, whence they.are delivered out of the machine, or,
if desired, the drawing action may be continued by means of an additional gill.or

second gill roller acting in such case as retaining rollers.
In the accompanying drawing,
:
Fig. 1 shows in longitudinal section so much of a fibre drawing machine, with
iny improvements applied thereto, as will serve to explain the mode of carrying
out my invention.
Fig. 2 is a transverse, section in the line 1. 2 of Fig. 1, and
Fig. 3 is a partial plan view, seen from above.
In my system of drawing, A A' are the gill or card rollers, interposed between
which is a smooth feed roller B', surmounted by a pressure roller C', also smooth,
in metal, or covered with wood or leather, which feed rollers are the counterpart of
the rollers B, C. This arrangement of card and feed. rollers is preceded by a
grooved delivering roller D, with pressure roller E, and followed by a grooved
drawing roller F, with pressure cylinder G, covered with caoutchouc, parchment,
or leather.
The feed rollers B B' are moved by gearing, while their pressure cylinders C C¹
may be moved by gearing, or by simple contact. These last may naturally vary
in diameter; their pressure may also be augmented by the help of weights or
.springs.
The gill or card rollers A A' may be disposed in such a manner that the material
passes above or below them, which does not alter the result.
To provide for the proper drawing action, the surface speed of each gill or card
roller is made slightly superior to the surface speed of the rollers by which it is
fed, and in the case of the feed rollers which act also as drawing rollers, their
surface speed will be slightly superior to that of the card roller from which they
draw the fibres.
The gill or card rollers, and the feed and drawing rollers, are supported.by a
metallic block I, covered with a cap I', held down by the bolts and b', one of
which,, in concert with that c, serves to fix the said block I on the frame J of the
machine. The pressure rollers are, mounted in grooves a a, which leaves them free,
and permits of varied diameters of pressure rolls being used. The pressing roller G
is mounted in a bracket 1', on the side of which is formed a trough destined to
support the axis of a licker-up cylinder, covered with plush, and designed to clean
the cylinder G.
The gill rollers, it will be seen, stand up above the line of bite of the retaining
and drawing rollers, and by this means l'ensure the fibres bedding well into the
pins of the rotating gill or card rollers. The surface speed of the various rollers
will be adjusted to suit the amount of "drawing" required.
The interposition of the feed rollers between the gill or card rollers, permits of
the engaging of the material more regularly into the pins of the second and
following gill or card roller, and that by a distinct action for each gill or card
roller. Further, the fibres are better disposed to be regularly drawn, in the sense
that they are alternately retained by the pins of a gill or card roller, which enter
into the
mass of the sliver, and by the feed and pressure rollers, which, in
compressing the sliver, detain the fibres better than the pins of the gill or card
rollers.
It will be understood, that the number of gill or card rollers arranged in series,
with interposed feed rollers, may vary according to requirements, and that I
reserve to myself the right to change the forms, dimensions, and material of each
of the constituent organs of my system of drawing.
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
The novel arrangement of machinery above described for drawing waste silk,
wool, or other textile materials, in which two or more card rollers are employed,
each gill or card roller being preceded by a feed and pressure roller, the interposed

page_text: rollers having for their object the better engaging of the material in the pins; of
acting as a retaining device during the drawing, and of acting equally as a
drawing device for disengaging the material from the pins of the preceding gill or
card roller.
