GEORGE PETER LEIGH, of Manchester, in the County of Lancaster. "IMPROVE-
MENTS IN THE CONSTRUCTION OF MACHINES KNOWN AS SLUBBING, INTERMEDIATE,
AND ROVING FRAMES USED IN THE PREPARATION OF COTTON AND OTHER FIBROUS
SUBSTANCES FOR SPINNING."
My Invention relates to that class of slubbing, intermediate, and roving frames,
wherein the flyer, instead of being fixed on the top of the spindle and driven
thereby as usual in such machines, is entirely disconnected from the spindle, and is
driven independently thereof.
According to my Invention a short tube or neck at the top of the flyer is carried
in a fixed longitudinal rail (or rails), or in brackets attached to the front of the
roller beam, and the bearing or journal of the same is secured by a cap or caps
placed loosely in a recess or slot in the longitudinal rail or bracket so as to be
easily taken out when required. The flyer is not detached for doffing. The flyer
is driven from a flange on a skew bevil wheel (which at present drives the bobbin),
and has a disc or ring rivetted onto its lower arms or legs, which ring is provided
with holes or notches, in which pass studs which project upwards from the flange
of the wheel and thus drive the flyer; or the ends of the flyer-arms may pass into
holes in the flange wheel, which thus drives the flyer direct; or to shorten the
flyer legs the same can be driven by long hollow studs or tubes secured in the
flange of the wheel to allow the flyer legs to drop into them.
This gear is attached to a fixed rail, which also carries long bolsters, in which
the spindles revolve.
The lower rail, which carries the footsteps supporting the spindles, is movable,
and has a rising and falling motion, carrying the spindles and their driving gear
with it, and has also a copping motion applied to it. This rising and falling
motion for winding on the roving may be imparted to the spindle rail by either
toothed gear or screws.
The upper end of the spindle is reduced in diameter to admit a smaller size of
tube or bobbin which is driven by the spindle. The tube or bobbin may be of
metal, paper, or wood, and is doffed from the spindle (when lowered to its lowest.

to commence winding on a fresh tube from the top, so as to get a firmer bobbin
and more uniform winding or taking up at the commencement.
The taking up is regulated by varying the speed of either the spindle or the
flyer by means of the usual cone drums applied to either of them.
The spindles may be made of cast iron or the ordinary steel, and by preference
hollow. The flyer tops are made of cast iron in preference, and the legs or arms
steel, and screwed to the tops.
The rail gear, which drives the flyers, being stationary, the casings for the
spindle wheels can be made in panels reaching from the same to the floor, and
made to open in sections for cleaning and oiling when required.
The balance chain or rope for the counterweights for balancing the spindle rail
are secured by eyelet bolts fastened to the centre of the lifting rail, and the first
carrier pulley for the same is fixed to the centre of the rail above to give a more
direct lift when working.
The spindle rail can be more perfectly worked by sliding up and down vertical
single column or double columns in lieu of the present system.
