WILLIAM WHITELEY, of the Firm of William Whiteley and Sons, of Lockwood,
near Huddersfield, in the County of York. "IMPROVEMENTS IN MACHINERY OR
APPARATUS FOR SPINNING WOOLLEN OR OTHER FIBROUS SUBSTANCES."
This Invention relates more particularly to machinery for spinning, for which
Letters Patent were granted to me, bearing date the 21st May, 1874, No. 1804, and
the 26th June, 1876, No. 2628.
The object of the first part is to effect variations in the tension on the yarn
during the draught similar to that which takes place in mule spinning, caused by
the thread slipping off the top of the spindle. I accomplish this by means of
oscillatory fingers or rods, so arranged as to bear upon the thread at intervals, and
by forcing them out of their ordinary line and then releasing them and allowing
them to return there; the tension is varied as desired to any required extent.
Secondly. My Invention relates to the employment of mechanism for retaining
the end of the yarn during the process of dofting or changing bobbins, cops, or
spools, so as to dispense with the necessity of attaching each thread of yarn
separately to the new bobbin. Upon the spindle I attach by set screw or peg, or
other equivalent, a cap, which is about the same size, and serves in place of the
ordinary "button" or spool rest. A portion of the flange or rim of this cap is cut
away for the purpose herein-after described. A suitable distance below this is a
washer or collar, either fast to the spindle or moveable only in one direction. Between
the collar and the cap is a spiral spring, one end of which rests on the washer or
collar, and the other bears against an internal rim or flange formed on the top of a
barrel or tube which covers the said spiral spring, and is of sufficiently large
diameter to slide over the bottom washer or collar upon which the spring rests. The
top of the barrel or tube enters the cap first mentioned, and the upper part of each
barrel or tube passes through a hole in a rail called the barrel rail, extending from
end to end of the machine, and which is capable of being raised or lowered by hand
wheel, levers, or other means.
When the machine is ready for doffing, the rings of an ordinary ring spinning or
doubling frame are let down below the bobbin, and the barrel rail is also depressed

page_text: or lowered a little, coming into contact with projections on the bottom portion of
the said barrel or tube, causing an opening between the top of the barrel and that
portion of the cap where the rim is cut away. The whole of the spindles then
receive a turn by hand, which causes the yarn to enter these openings, after which
the barrels or tubes are released and the spiral spring nips the yarn firmly between
the barrel or tube and cap, so that when the bobbin is doffed the yarn will break,
leaving one end nipped fast in between the flange or rim and barrel or tube.
Empty bobbins being supplied the rings are raised to the proper position, and the
thread commences at once to wind on the bobbin, and after it has got well hold the
barrels or tubes are again depressed whilst the machine is in motion, and the ends
thus released fly out by centrifugal force.
This latter part of my Invention is equally applicable to ordinary spinning
frames as well as to those constructed according to the Patents herein-before
referred to.
