IMPROVEMENTS IN MACHINERY FOR WINDING YARN
Year: 1876

page_text: LETTERS PATENT to William Henry Hacking, of Bury, in the County of
Lancaster, Machine Maker, and Thomas Edward Wilson, of Lille, France,
Engineer, for the Invention of "IMPROVEMENTS IN MACHINERY FOR WINDING
YARN."
Sealed the 23rd February 1877, and dated the 6th September 1876.
PROVISIONAL SPECIFICATION left by the said William Henry Hacking and
Thomas Edward Wilson at the Office of the Commissioners of Patents on the
6th September 1876.
WILLIAM HENRY HACKING, of Bury, in the County of Lancaster, Machine
Maker, and THOMAS EDWARD WILSON, of Lille, France, Engineer. "IMPROVEMENTS
IN MACHINERY FOR WINDING YARN."
This Invention consists,-
First. In certain improvements upon the machinery for which Letters Patent
were granted to Edward Booth on the 20th day of March, 1873, Number 1040.
And, Secondly. In an improved mode of constructing pirn bobbins.
In the winding machine above referred to-patented by the said Edward Booth
the pirn bobbin required a conical head and was turned by contact with a corre-
sponding conical disc, now our Invention consists in driving the spindle first by a
friction pulley on the spindle diiven by the outer circumference of the conical disc,
whereby the yarn is wound on a paper or metal tube, or on the bare spindle, and
the conical head of the pirn bobbin is dispensed with.
Our improved pirn bobbin consists of a metal tube on which are corrugations or
projections to prevent the slipping of the yarn when it is drawn off, and of a
conical head made of wood or other suitable substance.

IN MACHINERY FOR WINDING YARN."
The nature of our Invention consists,―
First. In certain improvements upon the machinery for which Letters Patent
were granted to Edward Booth on the 20th day of March, 1878, Number 1040.
And, Secondly. In an improved mode of constructing pirn bobbins.
Our improvements upon the machinery above referred to consist in certain
additions thereto whereby the machine is adapted to make.cops on the bare spindle,
or on paper or metal tubes.
In carrying out our improvements we make the spindles on which the pirns or
cops are formed loose, and to revolve in bearings instead of being fixed to the
presser, as shewn in the Patent of Edward Booth above referred to. The spindle is
shewn at A in Figs. 1 and 2 of the accompanying Sheet of Drawings, and it revolves
in the presser T and footstep M.
The presser T is fitted in one arrangement with a steel point or centre, shewn at 1
in Fig. 1, which is made to work in a countersink in the end of the spindle A; also
with a steel bit 2 to keep the spindle in a vertical position, and a box or hollow
part 3 in which a little greasy wool is put to lubricate the spindle end.
In another arrangement the presser is fitted with a step of lignum vitae wood,
shewn at 1 in Fig 2, and the spindle end is round or egg shaped. This wood boing
hard and of a greasy nature is very suitable for this purpose The footstep M
consists of a bracket with a hole or slot through which the spindle slides.
Fig. 1 shews our improvements as arranged to wind yarn on paper or metal
tubes; and Fig. 2 shews the arrangement to wind yarn on the bare spindle. In
Fig. 1 B is the paper or metal tube on the spindle, and C the disc which turns the
same. Fig. 1 shows the arrangement at the moment the cop is commenced, and
Fig. 2 when the cop is partly formed.
In making cops either on the spindle or on tubes it is necessary to form the
conical foundation of the same by driving the spindle or cop in some other way
than that contemplated in the Patent previously mentioned, because at the com-
mencement the cop has no contact with the conical part of the driving disc. In
order to make the spindle rotate while the conical bottom or foundation is formed
we apply at the top of the spindle A, Figs 1 and 2, a movable friction pulley G
which is attached to the spindle A by a fast key, but can move up and down
between the collars E and H freely. The friction pulley G is made to come into
contact with the driving disc C when the cop begins to be formed, and this contact
causes the spindle to rotate. As the layers of yarn accumulate the spindle rises,
but the friction pulley G falling on the spindle by its own weight remains in
contact with the disc C until the conical part of the cop is formed; after this the
further contact of the friction pulley G with the disc ceases by the collar H carrying
it upward with the ascent of the spindle. The conical part of the cop being thus
formed the remainder proceeds in the usual way, the spindle being driven by the
contact of the cop with the disc till the cop is completed
Our improved pirn bobbin is shewn in Fig. 3, and consists of a metal tube X
made of thin sheet steel, iron, or other metal, on which are slights corrugations
which are for the purpose of holding the yarn placed on it, and effectually preventing,
the same from slipping off; or the same object may be obtained by dispensing with
the corrugations and covering the tube with paper or other material which by its
roughness will hold the yarn The conical part of the pirn Z is made of wood,
fitted very tightly on the metal tube; the advantages of such pirns being great
durability and a capability of holding more yarn than pirns made entirely of wood
in the usual way.

page_text: Having thus stated the nature of our improvements, and described how the same
are to be carried into operation, we claim as our Invention,-
First The revolving spindle fitted up with presser and footstep, as shewn and
described.
Secondly. The method of forming the conical foundation of the cop wound on
the bare spindle, or on paper tubes, metal tubes, or any mere modification of the
same.
And, Thirdly. The improved pirn with metal stem or tube and wood conical
part.
In witness whereof, I, the said William Henry Hacking, for myself and of
behalf of the said Thomas Edward Wilson, have hereto set my hand and
seal, this Second day of March, One thousand eight hundred and seventy-
seven.
