PROVISIONAL SPECIFICATION.
Improvements in Cop or Pirn Winding Machinery.
We, EZRA SYKES and DAVID SYKES, of Turnbridge Iron Works, Huddersfield,
in the County of York, Machine Makers, do hereby declare the nature of this
invention to be as follows:-
Our invention has reference to machines employed in winding yarn upon a bobbin
or spool driven by a vertical spindle. In this class of machine the bobbin rises
vertically as the yarn is being wound upon it, and it has hitherto been unpracticable
to wind yarn upon a long bobbin, because when the said bobbin was nearly full it
projected or stood up to such an extent as to vibrate considerably and would jump
from between the cones or out of the cup in which it was rotating. The object of
our invention is to provide means whereby the spindle and bobbin may be steadied
and the vibration complained of avoided. In carrying out our invention we employ
one or more upright pillars on which is placed loosely, a boss or collar for the
purpose of bearing upon the upper end of the spindle or upon the upper end of the
bobbin. The boss is free to slide up and down the pillar or pillars so that as
the bobbin rises as each layer of yarn is wound upon it, the boss rises with it
whereby the spindle and bobbin are kept perfectly steady and permits us to run
the spindles at a greatly increased speed, consequently a large amount of work can
be done in a given time. When doffing or changing the bobbins, the boss is slided
up its pillar or pillars and held there by a catch so that it does not stand in the
way of the operative.
When winding strong yarn and a firm solid cop is required, the sliding boss
which bears upon the top of the bobbin or spindle may be weighted so as to apply'
friction on the yarn; but when winding tender yarns, we propose to connect a
weighted cord or chain to the sliding boss so as to counterbalance the weight of the
boss, by which means the weight of it, is removed off the bobbin or spindle whereby
it steadies the spindle without weighting it. Instead of the spindle being free at
both ends, we may construct the upper end of it with a ball and socket joint and
connected with the sliding boss in which case the bobbin would be drawn off the
bottom of the spindle, instead of the top as at present.

Improvements in Cop or Pirn Winding Machinery.
We, EZRA SYKES and DAVID SYKES, of Turnbridge Iron Works, Huddersfield,
in the County of York, Machine Makers, 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:-
Our invention has reference to machines employed in winding yarn upon a bobbin
or spool driven by a vertical spindle. In this class of machine the bobbin rises
vertically as the yarn is being wound upon it, and it has hitherto been impracticable
to wind yarn upon a long bobbin, because when the said bobbin was nearly full, it
projected or stood up above the cones or cup to such an extent as to vibrate
considerably and would jump from between the cones or out of the cup in which
it was rotating. The object of our invention is to provide means whereby the
spindle and bobbin may be steadied and the vibration complained of avoided.

page_text: Such being the nature and object of our invention, we will now proceed to describe
the same more fully, and for that purpose make reference to the accompanying
sheet of drawings, wherein Fig. his front elevation of our improved apparatus and
Fig. 2. is. side elevation of same... A represents the spindle, the bottom of which
enters into a recess in the top of the wharle B' by which the said spindle is driven.
Care cones capable of revolving lightly upon centres D, and they are placed in an
oblique or angular position so as to form: or leave a conical space between them for
the purpose of forming or building up the cop as-is well understood and which forms
no part of our invention. Our improvements comprise devices or appliances to
enable us to wind yarn upon a long bobbin placed in a vertical position as shewn
at E. The cones revolve on the base plate F which is attached to the framework
of the machine; and rising up vertically above base plate Fare two pillars G
connected together at the top by a bar or bridge H, and upon these pillars are
bosses I placed loosely thereon and free to slide up and down. The two sliding
bosses are connected together by cross piece also carrying a boss K'which
receives the upper end of the spindle A whereby it is steadied and oscillation
thereof prevented. In cominencing to wind the yarn upon the bobbin the boss k
rests: upon the head of the bobbin, and as each layer of yarn is wound upon the
bobbin the latter rises in the same proportion and this goes on until the bobbin'" iš
full, and as the bobbin and spindle are kept perfectly steady by the means' above
describedt we can run the spindle at a greatly increased speed consequently a larger
amount of work can be done in a given time. When doffing or changing the
bobbin the bosses are slided up the pillars and retained there by the catch L so that
the bosses and cross piece do not stand in the way of the operative:
Wien' winding strong yarn, and a firm solid cop is required, the sliding boss K
which bears upon the top of the bobbin or spindle may be weighted so as to apply
friction on the yarn; but when winding tender yarns, we propose to connecti a
weighted cord or chain to the sliding boss K so as to counterbalance the weight of
the boss, by which means the weight of it is removed off the bobbin or spindle,
whereby it steadies the spindle without weighting it. Instead of the spindle being
free at both ends, we may construct the upper end of it with a ball and socket
joint and connected with the sliding boss, in which case the bobbin would be drawn
off the bottom of the spindle, as at present.
!
Having now particularly described and ascertained the nature of our said inven-
Lion,, and in what manner the same is to be performed, we declare that. what we
claim is :-
Firstly. In a cop or pirn winding machine,. the combinationt therewith of the
vertical pillars G and sliding weight K operated in the manner and for the purpose
described herein.
Secondly. In a cop or pirn winding machine, the use of the catch L for holding
or retaining the sliding weights in manner substantially as shewn and described.
Thirdly. In a cop or pirn winding machine,. thé. means and method substantially
as herein shewn and described for steadying the spindle and bobbin asset forth.
