Rochdale in the County of Lancaster for an Invention of IMPROVEMENTS
IN MACHINERY FOR PREPARING SPINNING AND DOUBLING COTTON SILK
PROVISIONAL SPECIFICATION left by the said Thomas Berry at the Office
of the Commissioners of Patents on the 14th September 1882.
THOMAS BERRY, Machinist, Barlow Street, Water Street Rochdale in the
county of Lancaster IMPROVEMENTS IN MACHINERY FOR PREPARING SPINNING
AND DOUBLING COTTON SILK WORSTED AND OTHER FIBROUS SUBSTANCES.
I propose in Slubbing Intermediate Roving, Spinning or Doubling frames, to
form the top of the spindle or flyer, straight, taper or round with one or more
grooves in it for the yarn to pass through, and to this part I apply a bearing which
also has a slit formed in it for the yarn to pass through; this bearing is attached
to the machine by any convenient means but so as to be lifted off the top of the.
spindle when required for changing the bobbins or other purpose. When applied
to spinning or doubling frames propose to attach this bearing to the guide wire
board or guide plate; by this means it can be easily lifted off the top of the
spindle. On the top of this bearing is formed or fixed a wing which has a slit
or slits made in it to catch the yarn when it snarls. Along side of the bearing
is formed a cavity which is filled with sponge or other absorbent material to
contain oil; this cavity is connected with the hole into which the spindle or flyer
top passes, by means of a groove or channel, for the oil to pass through to the
spindle or flyer top, to lubricate it.

IMPROVEMENTS IN MACHINERY FOR PREPARING SPINNING AND
DOUBLING COTTON SILK WORSTED AND OTHER FIBROUS SUBSTANCES
"
My Invention relates to improvements in Slubbing, Intermediate Roving
Spinning and Doubling Frames and consists in forming the top of the spindle
or flyer straight taper or round with one or more grooves in it for the yarn to
pass through and to this part applying a bearing which also has a slit formed
in it for the yarn to pass through, this bearing is attached to the machine by any
convenient means but so as to be lifted off the top of the spindle when required
for changing the bobbins or other purpose. When applied to spinning and
doubling frames this bearing may be attached to the guide wire board or guide
plate (by this means it can easily be lifted off the top of the spindle) and on the
top of the bearing I form or fix a wing which has a slit or slits made in it to catch
the yarn when it snarls. Fig 1 is an elevation and Fig 2. a plan of the bearing
as it may be applied to Slubbing Intermediate and Roving Frames. a is the top
of the flyer which revolves in the bearing b. which is connected to the bracket c.
by the joint d. the bracket c. is fastened to the roller beam e. by any convenient
means. The spring f. keeps the bearing b. down on the flyer top when in the
position shown and when lifted up for changing the bobbins or other purpose
prevents it falling again. Fig. 3 is an elevation partly in section and Fig 4. a plan
view showing another way of applying my Invention to Slubbing Roving and
Intermediate frames. a is the flyer top and b. the bearing which goes inside the
flyer top instead of outside as shown in Figs 1 and 2. If required the bearing
might go both inside and outside the flyer top. Fig 5. is an elevation and Fig 6.
a plan of the bearing as applied to the spindle tops of spinning and doubling
frames a. is the top of the spindle which has a groove formed in it for the thread
to pass through this is supported by the bearing b. which is fastened to the wire
board c. which is fastened to the roller beam d. by the hinge e, by this means
the bearing can be lifted off the top of the spindle when required f is a projection
formed on the bearing b. with a slit cut in it which takes hold of the yarn when
it snarls and thus prevents waste. The bearing b. might take hold of the top
of the flyer when the grooves for the yarn to pass through would have to be
formed in the flyer top. Having now described my Invention and shown how
the same may be carried into effect I wish it to be understood that what I claim
as my Invention is: 1st. The bearing b. which takes hold of the top of the Flyer
in Slubbing Intermediate and Roving frames which is fastened by means of a
hinge to the roller beam or other convenient place so as to be easily lifted off the
top of the flyer when required for doffing or other purpose substantially as described
in reference to Figs 1. 2. 3 and 4. 2nd The bearing b. which takes hold of the top
of the spindle or flyer in spinning and doubling frames substantially as shewn
and described in reference to Figs 5. and 6 3rd The projection f. with slit to catch
the yarn when " snarling" see Figs 5. and 6. 4th Forming a groove or grooves in
the top of the spindle or flyer of spinning and doubling frames for the yarn to pass
through substantially as shown and described in reference to Fig. 5.
In witness whereof I the said Thomas Berry have hereunto set my hand
and seal this thirteenth day of March in the year of Our Lord One thousand
eight hundred and eighty three.
