Improvements in Spindles for Spinning Machinery.
A communication to me by the ST. BLASIEN SPINNING MILL COMPANY, of
St. Blasien, Baden, in the Empire of Germany.
I, EDMUND EDWARDS, of the firm of Edwards and Co., Patent Agents and
Engineers, of 35, Southampton Buildings, Chancery Lane, in the County of
Middlesex, 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 and accompanying drawing, that is to say :-
In the improved apparatus which forms the subject of this invention, the yarn or
thread issuing from the drawing rollers is guided in order to be wound either upon
the spindle or upon a paper sheath fixed thereon, in such manner that the cleaning
of the thread or yarn, or the removal of defective parts such as thickenings, are
effected, and the quality of the yarn greatly improved.
In the accompanying drawing which is in illustration of the invention, Figure 1
is a view of the spindle shewing the circular holder or frame in its lowest position.
Figure 2 is a longitudinal section of the spindle shewing the finished conical part of
the cop. Figure 3 is a view of a spindle shewing the circular holder in its highest
position, and Figures 4 and 5 are respectively a side view and plan of the winding
up apparatus.
The apparatus consists of a short tube A. to the lower part of which the disc B
is fixed, whilst its upper part carries a wire ring C capable of turning and sliding
up and down thereon, and furnished with eyelets which may be vertical or inclined.
The short tube A with the disc B and the wire ring C, are placed upon the empty
spindle E, which may be provided with a paper sheath D as shewn on the drawing,
or may be without the same. The paper sheaths are only used for imparting greater
strength to the cops for transporting purposes.
The yarn or thread proceeding from the drawing rollers is passed through one of
the eyelets of the wire ring C, and laid round the edge of the disc 13, being further
drawn through the rummer (r, moving upon the annular holder or frame F and fixed
at the bottom to the paper sheath B or to the spindle, so that at the commencement
of an operation the annular holder and the apparatus assume their lowest position,
as shewn in Figure 1.
When the spindle commences to rotate, all the parts of the apparatus are set in
motion, the disc B sets the runner G in motion, and the wire ring C holds the yarn
or thread against the disc B, so that a sufficient tension is thereby obtained.
The disc operates upon the runner with a force proportionate to the acuteness of
the angle formed by the disc and the frame, that is to say to the extent of motion of
the annular holder toward the disc. It is thus rendered possible to wind upon the
empty thin spindle. The runner and wire ring have the same speed, which increases
or decreases according to the diameter of the cop.
Owing to the movement of the traverse rail of the spinning machine, the annular
holder as well as the apparatus is constantly pushed upward, and the latter assumes
the position shewn in Figure 2, and when the cop is entirely finished the annular
frame or holder and the entire apparatus occupy their highest position, as shewn in
Figure 3. The disc B may have a diameter of any convenient size and may be
larger than the holder F.
As compared with other winding devices of a similar kind, this apparatus is
particularly advantageous for thin spindles having a high number of revolutions,
and for either warp or weft varns in fine numbers.

page_text: Having now particularly described and ascertained the nature of the said inven-
tion, and the manner in which the same is to be performed, I declare that what I
claim is
A
A winding up apparatus for spinning machinery, consisting of a short tube
placed upon the spindle and provided with a wire ring C capable of being rotated
and moved up and down thereon, and with a disc B, this tube being raised by the
annular frame or holder F, whilst the thread or yarn passed through an eyelet on
the ring C, laid round the disc B, and drawn by the runner G, is wound upon
the spindle as the latter rotates, substantially as described and shewn in the
drawing.
