Improvements in Machines for Winding Yarn or Thread.
I ROBERT SEIFERT, Workmaster, of Oelsnitz in the Province of Saxony,
Germany, 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 :-
This apparatus is drawn in
Fig. I in a side view with the spool pressed close,
Fig. 2 in a section,
Fig. 3 in a side view with the spool disengaged, while
Fig. 4 shews somewhat altered details.

In the frame A of the winding-machine the drum, roller or disc B revolves, and
by its revolution takes along the spool C, which is pressed against it and drives it
round. The spool C is fixed in the fork-shaped end a₁ of a joint-lever D, revolving
at b. The other end a, of this joint-lever is also formed in the shape of a fork, and
carries in the fork a guide E, which can easily be adjusted by means of screws c
and d. This guide E is for a sliding-weight F. At the commencement of the
revolution of the spool, the end e, of the guide E lies somewhat lower than the
middle of the guide at the screw c, and at this lowest point is the weight F and it
thus presses the spool against B. In proportion as the spool is filled with thread,
thus receiving a greater diameter, the end of the joint-lever D, that bears the spool,
rises and with it the end of the guide, till at last, when the spool is full, the end e,
of the guide lies lower than e₁. On account of this the weight F slides towards
the end e, produces an over-weight at this point, and thereby throws the joint-
lever D backwards about b as far as the pin on the guide, which presses against
the frame of the winding machine, allows. Hereby the spool is lifted off or dis-
engaged. When a new spool is put in, a pressure of the finger on the horn g at the
point e, in the guide E, is sufficient to lower the guide in front, and to cause the
weight to slide forwards and the spool again to press against the driving-cylinder A.
If the sliding-poise F is of considerable weight, different sizes may be wound at
will with the same apparatus. It is only necessary by loosening or tightening the
screws c and d to raise or lower the end e, of the guide, according to the size of the
spools, in which case the bow h serves as guide. This bow should also be used for
marking the position of the guide for sizes of spools that are frequently being used,
in order to avoid the trouble of having to try, each time a different size is put on.
Instead of being fastened to the guide, as is done in the first three figures, the
bowh may also be attached direct to the fork a, of the joint-lever D.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what I
claim is:
Automatic arrangement for disengaging spools in winding-machines, worked by
the sliding-weight F, sliding in a guide E, which is so fastened to one end a, of the
joint lever D, that it can be adjusted, while the other end a, of the joint-lever D
which is attached to and revolves at the point b, carries the spool C.
