DAVID DAVIES, Mill Manager to Messieurs Samuel Hollins and Company, of
Astley Bridge, near Bolton, in the County of Lancaster. "IMPROVEMENTS IN THE
CONSTRUCTION OF MACHINERY OR APPARATUS EMPLOYED IN SPINNING AND
DOUBLING COTTON AND OTHER FIBROUS SUBSTANCES."
The object of this Invention is to obtain greater perfection and higher speed in
machinery of the ring frame and throstle class, and it is applicable to the spinning
and doubling of cotton, wool, silk, flax, and other vegetable and animal fibres.
To carry into effect these improvements I employ a stationary tube or bolster
fixed in a suitable rail, and the interior of the said tube may be chambered out to
diminish the friction.
In this stationary, tube is a loose running tube so formed as to fit only at each
end, to which is firmly attached an inverted flyer having a ring fixed to the upper
part of the wings to stiffen them, and render the flyer capable of high velocity.
This arrangement creates no obstruction or impediment to the doffing of the
bobbin or cop, which can be done with the greatest facility. On the upper part of
the loose tube and below the flyer a wharve or pulley is firmly fixed, by means of
which the tube with its accompanying flyer is driven by a band direct from the
tin roller.
The spindle passes through this tube and up the centre of the flyer to the desired
height and carries the yarn, whether it be spun upon the bare spindle, or upon a
tube, or a bobbin placed thereon. If a tube or bobbin be used I fix a collar on the
spindle (above the boss of the flyer) to support the same. The spindle is not
driven directly, but merely dragged down by the yarn, thus acting as a "drag."
Should more "drag" be required than the spindle itself imparts, it may be obtained
by fixing a light wharve or pulley to the spindle, against the circumference of
which a band may be caused to bear with a small weight attached to keep it in
position, and the "drag" can thus be nicely adjusted by giving the band a greater
or less amount of friction against the wharve, either by moving it along a notched
plate fixed upon the rail, or by a self acting mechanical adjustment or otherwise.
This mechanical adjustment may be effected by means of a ratchet wheel and
worm attached to the notched plate, or by other mechanical appliances, thus moving
the plate slightly to cause greater friction of the band against the wharve as the
[Prins 211

page_text: bobbin or cop increases in size, by this means equalizing the " drag" from the
beginning to the end of the set.
The twist is imparted to the yarn by means of a disc plate or ring in which are
fixed one or more small hooks or guides through which the yarn is passed, and this
disc plate or ring being fitted, but not fixed to the wings of the flyer is rotated by
them at great speed, and so gives twist to the yarn; and being carried by a suitable
rail or bar, which is caused to rise and fall by means of a traversing motion, it will
wind the yarn properly upon a bobbin, or will build it in the form of a cop, as may
be required.
