"IMPROVEMENTS IN THE CONSTRUCTION OF MACHINERY OR APPARATUS FOR
SPINNING AND WINDING COTTON OR OTHER FIBROUS SUBSTANCES."
My Invention relates to the construction of a machine intended to spin yarn and
wind it into the form of a cop at one operation, which I propose to do by means of
a machine somewhat similar to that at present in use for putting twist into
rovings and winding the same onto bobbins, but with certain modifications as
hereinafter described.
In the first place I use a ring or hollow cylinder instead of a flyer in connection
with the spindle, and in order to attain a greater speed I substitute grooved
band pulleys for toothed wheels usually employed for driving the spindles and
rings or cylinders.
The latter I drive from a grooved pulley keyed direct on the main driving shaft,
which is driven at such a speed as will impart the requisite speed to give the proper
amount of twist to the yarn, carrier pulleys and bands being so arranged as to
allow the ring or cylinder to rise and fall as the yarn is wound onto the cop at the
same time that it is driven by the band, without the latter becoming slack.
On the end of the main driving shaft is keyed a spur pinion, which by means of
a train of spur gearing drives a cone (or frustrum of a cone) at a greatly reduced
speed. This cone or frustrum drives another cone or frustrum (with its apex
reversed), but instead of communicating the power by means of an endless strap I
make use of the following arrangement:―
On the surface of the driving cone or frustrum I fix or form a spiral projecting
strip, commencing at a point at the smaller end of the cone or frustrum, and after
passing in a spiral direction to the opposite point of diameter at the larger end,
returning spirally to the original point of departure at the smaller end of the cone
or frustrum.
The driven cone or frustrum is provided with a similar spiral projecting
strip.
The effect of this arrangement will be that the second cone or frustrum will be
driven at a gradually increasing speed for the first half of each revolution of the
driving cone, and at a correspondingly diminishing speed for the second half of each
revolution.

page_text: Or instead of the spiral projections, pegs may be fixed in a spiral line on one
cone, and corresponding holes formed in the other, or the latter may be simply
grooved in a longitudinal direction, which will produce the same effect.
The movement of the second (or driven) cone or frustrum is communicated
through a train of spur gearing to the spur wheel of what is well known as
an equational box," or "differential movement," (as employed in the "bobbin and
fly frame.")
"
The first mitre wheel of this movement is keyed fast outo the main driving shaft,
the second and third mitre wheels are carried in the web of the spur wheel above
mentioned round the first, and the fourth mitre wheel in gear with the second and
third is placed loosely on the main driving shaft, and to it is fixed the grooved
band pulley which drives the spindles.
The consequence of this arrangement of gearing is to cause the spindles to turn
at the same time as the flyers, and to gain the requisite motion in addition to
wind on the yarn, the action of the cone arrangement above described causing this
winding on movement to increase or decrease as the diameter of the cop alters by
the rising and falling of the ring or cylinder.
