A NEW COP-WINDER.
In Germany extensive use is made of a cop-winding machine in which the
wooden spindle consists of a cone moved by a screw, and the position of
which is horizontal. Fig. 1 shows the primitive type of the German
apparatus, in which the cone that forms the cop is set in motion by a
horizontal screw. It is at first the greater diameter of the cone that
moves the tube, and permits the thread to accumulate beneath the narrow
extremity. But, as soon as a core of thread has been formed, it is in
contact with the entire surface of the cone, and thus revolves with a
mean velocity until it is finished.
In the new model (Fig. 2) the arrangement is different. Here A is the
paper tube, with wooden base, to which it is freely attached, and C is
the cone that moves over the screw, D. The thread passes into a groove
which makes one revolution of the cone, and from thence over the paper
tube, where it receives the form of a cop by reason of the transverse
motion of the cone upon the screw. This transverse motion is at first
prevented by the click, F, which falls into the teeth of the
ratchet-wheel fixed behind the cone. The shaft revolves continuously,
but has, at the same time, a to and fro motion in the direction of its
axis, so as to cause the thread to move forward constantly and form a
cop.
