Mulholland Porter, of Belfast, in the County of Antrim, Ireland, for the
Invention of "IMPROVEMENTS IN WINDING MACHINES FOR MAKING PIRNS
OR COPS."
Sealed the 6th April 1877, and dated the 25th October 1876.
PROVISIONAL SPECIFICATION left by the said Joseph Richardson Turtle
Mulholland and William Mulholland Porter at the Office of the Commissioners
of Patents on the 25th October 1876.
JOSEPH RICHARDSON TURTLE MULHOLLAND and WILLIAM MULHOLLAND PORTER,
of Belfast, in the County of Antrim, Ireland. "IMPROVEMENTS IN WINDING
MACHINES FOR MAKING PIRNS OR COPS."
This Invention relates to an improved and novel method of forming and rotating
or driving the pirns or cops in winding machines. To attain this object we use
revolving conical pullies for driving the pirns or cops by friction of contact with the
corresponding conical surfaces thereof instead of employing fixed cups or guides and
driving the pirn or cop through its centre. These conical pullies are caused to
revolve by suitable mechanism, and they give rotary motion to the pirn or cop
which is formed between the two adjacent cones, which all turn in the same direction.
The diameters and pitches of these conical pullies or drivers can be so arranged that
the pirns or cops are formed in each space between the conical pullies, and as they
are all in line they balance each other and prevent side wear. These conical drivers
may be placed either horizontally, inclined or vertically, and be driven by either
bands, tapes, gearing, or other mechanism, the conical surface of the pirn or cop
being pressed by suitable mechanism against the revolving surface of the conical
pullies, the apex of the pirn or cop coming into contact with the base or larger
diameter of the conical driving pullies.

JOSEPH RICHARDSON TURTLE MULHOLLAND and WILLIAM MULHOLLAND PORTER,
of Belfast, in the County of Antrim, Ireland. "IMPROVEMENTS IN WINDING
MACHINES FOR MAKING PIRNS OR COPs."
This Invention consists of an improved and novel method of forming and driving
the pirns or cops in winding machines.
The means whereby this is accomplished will be understood from the following
description and the accompanying Drawing, wherein the same figures and letters of
reference always apply to corresponding parts.
Fig. 1 is a sectional elevation or transverse vertical section of the machine; Fig. 2,
a partial plan; and Fig. 3 is a side view of a portion of the winding machine.
The peculiarity of this Invention is the use of the revolving conical pullies a
working in contact with the corresponding conical surface of the pirn or cop 6 instead
of using fixed cups or guides and driving the pirn b or cop through its centre, which
is the usual method. The pirn b or cop spindle is carried upon a spindle 6¹ which is
free to move endwise and rotate in its collar or neck c, the spindle 6' being supported
by a footstep e which is carried upon a lever e¹, Fig. 1, which is carried on a stud e¹
and balanced by a weight e². On this lever e¹ or handle is a wedge-like projection es
with a notch in the apex; this wedge e³ is acted upon by a weighted leverf which
presses on the surface of the wedge e³ so as to lift the spindle b¹ when on one side
and lower it when on the other. As the point of the weighted lever passes the
point or apex of the wedge e on the balanced lever e¹ it reverses the action, so that
when the point of the weighted lever f goes into the notch in the apex or point of
the wedge es it moves the pirn b just out of contact with the conical driving pulleys a
and retains the pirn b in that position when the pirn is full until the attendant
removes it and puts an empty one in its place. He then lifts the lever e¹ which
carries the footstep e into such a position that the weighted lever f presses on the
side of the wedge e³ so as to lift or press the pirn or cop into contact with the
conical pulleys a. The conical pulleys a are caused to revolve by pulleys and bands
as shown in the Drawing, or by any other suitable mechanism, and they give
rotary motion by friction of contact to the pirn or cop b which is formed between
two adjacent cones a as shown at Fig. 3, as these cones all turn in the same
direction.
The diameters and pitches of these conical pullies a or drivers are so arranged
that the pirns or cops b are formed in and fit each space between the conical
pulleys a, and as these are all in a line they balance each other and prevent
side wear. The yarn to be wound on to the pirns b or formed into cops by this
method is guided on to the pirn or cop b by oscillating or other guides b², Fig. 1,
actuated by a heart or other suitable mechanism in order to give the required
traverse to the yarn as it goes on to the pirn b. These conical driving pulleys may
be placed either horizontally, or inclined, or vertically, as shown in the Drawings,
and may be driven by either bands, tapes, gearing, or other mechanism.
The conical surface of the pirn or cop being pressed (by the mechanism just
described) against the revolving surface of the conical pulleys the apex of the pirn
or cop comes in contact with the base of the conical driving pulleys u.
Having now set forth the nature of our Invention of "Improvements in Winding
Machines for making Pirns or Cops," and explained the manner of carrying the same
into effect, we wish it to be understood that under the above in part recited Letters
Patent we claim, the use in winding machines of conical driving pulleys arranged
substantially as above described for driving pirns or cops by friction of contact,

page_text: whether the spindles be placed vertically, inclined or horizontally, and whether
winding from bobbins, spools, or banks.
In witness whereof, we, the said Joseph Richardson Turtle Mulholland and
William Mulholland Porter, have hereunto set our hands and seals, the
Twenty-third day of February, in the year of our Lord One thousand eight
hundred and seventy-seven.
