JOSEPH HENRY PICKLES of Burnley, in the County of Lancaster
MENTS IN MACHINERY FOR WINDING LINEN, COTTON, AND OTHER THREADS
This Invention has reference to machinery employed in unwinding thread off a
warping bobbin or reel, onto a pirn or spool bobbin or onto a spindle and the
object of my Invention is to fill such pirn, spool, or spindle hard with thread, and
this I accomplish by winding the thread thereon in such manner that more drag
or tension shall be put on the yarn whilst it is being wound upon the small part of
the pirn than at any other part, by which I obtain a good hard foundation which
prevents the thread slipping off when in the shuttle as is now the case.
For this purpose I employ self-acting mechanism which regulates the drag on
the warp bobbin or creel whether the thread is being wound upon the small part
or thick part of spool and this is effected without any attention on the part of the
workman.
The apparatus I employ consists of a bell crank lever hinged on a lever operated
by the "heart motion" of the machine. One end of this bell crank lever rests upon
the warp bobbin or creel and its weight thereon is regulated at the right time by
the lever operated by the "heart motion' so that most tension or drag is put on
the thread when it is being wound upon the small part of the pirn and the least
tension when winding upon the thickest part.
"
By this means most tension is put on the thread when it can stand most, and
least when less is required, consequently a firm and hard spool is produced fewer
breakages take place and therefore the machine can be run quicker.
The bell crank is so hinged that when the warp bobbin is full it bears with
more friction thereon than when it is getting empty and less in diameter.

This Invention has reference to machinery employed in unwinding thread off a
warping bobbin or reel onto a pirn or spool bobbin or onto a spindle; and the
object of my Invention is to fill such pirn, spool, or spindle with thread so that it
feels firm and solid when squeezed by the hand, and this I accomplish by winding
the thread thereon in such manner that more drag or tension shall be put on the 1
yarn whilst it is being wound upon the nose or small part of the pirn than at any
other part, by which means I obtain a good hard foundation which prevents the
thread slipping off when in the shuttle as is now the case.
For this purpose I employ self-acting mechanism which regulates the drag on
the warp bobbin or creel whether the thread is being wound upon the small part 1
or thick part of spool, and this is effected without any attention on the part of the
workman,
The apparatus I employ consists of a bell crank lever hinged on a horizontal
lever operated by the "heart motion" of the machine.
One end of this bell crank lever rests upon the warp bobbin or creel and its
weight thereon is regulated at the right time by the horizontal lever, so that most
tension or drag-is-put-on-the thread when it is being wound upon the small part
of the pirn, and the least tension when winding upon the thickest part.
In order that my Invention may be better understood, reference is given to the
accompanying Sheet of Drawings where Fig 1 is end elevation of a winding
machine having my improvements applied thereto which is shewn at A and
consists of a bell crank lever having its lower end a heavier than its upper end b,
whereby the upper end is always bearing upon the yarn as shewn in the drawings.
The lever is placed loosely upon a rod B extending the full length of the machine,
the rod being connected to, and actuated by a lever C whose fulcrum is at D. On
one part of the lever C is an anti-friction pulley working in cam grooves formed in
the wheels E (called the "heart motion ") by which an upward and downward
motion is given to the said lever. As will be understood and hereafter explained,
the upper end b of the lever A does not bear upon the bobbin F with the same
amount of pressure or weight continuously, as the fulcrum of the lever A by
means of the lever C is taken sometimes above, and sometimes below the centre of
the bobbin F consequently there is a varied amount of drag upon the yarn, and
this is regulated so as to be heaviest when it is necessary, and this happens when
the yarn is being wound upon the nose of the cop G, and the drag is lightest
when the yarn is being wound upon the largest diameter of the cop. The drawings
appended herewith illustrate exactly what is meant, the left hand end of the
lever C being in that position when the fulcrum of the lever A is below the
centre of the bobbin, the position of the said lever being such as to put more drag
upon the bobbin than when the fulcrum of the lever A is above the centre of the
bobbin as shewn at the right hand end of the lever C. The details Figs 2
and 3 illustrate the two positions of the lever A, the former showing the position
of the lever when acting upon a full bobbin, and the latter when acting upon
the barrell of the bobbin. It will be seen that when the apparatus herein
shewn and described is once set and adjusted, that it will be perfectly self
acting and reliable, allowing the yarn to be wound at a uniform tension from

page_text: the full down to the empty bobbin, and producing good solid pirns throughout.
By this arrangement there is also fewer breakages, as the greatest tension is
put upon the yarn when, practically it can endure most, and least tension when
it can endure least, consequently the machine can be run quicker and more work
produced in a given time.
I Claim.
The use and employment of mechanism for putting a varying drag upon the
yarn substantially as herein shewn and described.
In Witness whereof I the said Joseph Henry Pickles have hereunto set my
hand and seal this Twenty third day of April, in the. year of our Lord
one thousand eight hundred and eighty three.
