Improvements in Apparatus used for Spinning and Doubling Cotton
and similar Fibrous Substances.
I BENJAMIN WHITELEY of Brampton House, Elland, in the County of York,
Cotton Spinner, do hereby declare the nature of this invention and in what
manner the same is to be performed to be particularly described and ascertained
in and by the following statement:-
This invention relates to that kind of spinning apparatus for which Thomas
Ashworth obtained Letters Patent No. 11547, bearing date September 12th 1886,
the object of the present invention being to render the action of the said apparatus
more practically successful.
My improvements will be readily understood from the following description on
reference to the accompanying drawings.
On Sheet 1 Fig. 1 is a vertical section of so much of a spinning frame as is
necessary to illustrate certain parts of my invention and Fig. 2 is a detached view
of my improved tension pulley and its bearing, hereafter more fully described,
drawn to a larger scale.
On Sheet 2 Fig. 3 is a sectional elevation of the dead spindle, cup spindle, and
other parts hereafter described, Figs. 4, 5, 6 and 7 shew detached parts hereafter
more particularly referred to.
a a is the framing of the machine, 6 the bobbins on which the yarn is wound,
c the cup spindles, d the fixed rail, e the lifting rail, and f the tin roller or drum
from which the cup spindles c are driven.
It has been found in practice that when the side cup spindles c are driven in the
usual way by bands and wharves at very high speeds, say ten or twelve thousand
revolutions per minute, the bands were liable to become too slack to drive at full
speed and so to make soft yarn.
I therefore drive the said cup spindles by a strap or belt of suitable material
(preferably woven belting) and for this purpose I provide the cup spindles c with
pulleys c¹ as seen at Figs. 1 and 3 instead of the usual wharves.
Also in driving two spindles on each side of the frame by a single tape or strap g
passing round a tension pulley / mounted on a weighted lever i in the well known
way, I. employ special means for keeping the tension pulley h well lubricated. I
provide the pulley h with a hollow spindle ', as seen at Fig. 2, and I slightly
incline upwards the bush which carries the spindle h'. The lower end of this
bush terminates in a small oil reservoir 2 fixed or cast on the lever i. A hole h*
is made in the inner end of the hollow spindle which is also made with a spiral
groove on the outside thereof and running from end to end thereof, see Fig. 2.
Thus when the pulley his revolving the oil will run upwards to the hole * and flow
out between the spindle and the bush it, and into the spiral groove which will
return it to the reservoir, and thus a constant circulation of the oil will be kept
up and the bearing can not become clogged up with dust or "fly," as the bush runs
right up inside the pulley as shewn on Fig. 2.
I sometimes provide the lever i with a tube leading to the reservoir ², and a
receiver (see Fig. 1) so that the oil can be supplied to the reservoir 2 from above
(say through a hole in the thread board).
Thus the tape or strap g can be driven at a very high speed, and, the lubrication
of the parts being very perfect, there will be no tendency to breakage, and the use
of the said strap or tape ensures the full speed being imparted to the spindles.
Another part of my invention relates to the "dead" spindle k (see Figs. 3
and 7) which I make of a drawn steel tube. I fit a suitable footsten k¹ therein.

page_text: which supports the short spindle which carries the bobbin b, and also a bush k* at
the upper end to keep the spindle 1 steady. I bore a hole through the centre of
the footstep k¹, and this hole serves both to give a little drag to the bobbin
spindle as the bobbin b becomes fuller and heavier, and also to allow dirt to fall
through into the space 2 formed below the footstep by the filling piece k¹ inserted
in the spindle. This filling piece k may be made of cork or wood or be otherwise
removable.
I also form or fix an oil cup ³ at the top of the spindle the lower flange of the
bobbin serving as a cover therefor, (see Fig. 1) and I bore a hole in the
spindle & immediately below the bush k so that the spindle is lubricated.
At the bottom of the spindle I provide another oil cup m, which is adjustable
(as shewn at Figs. 3, 4, 5 and 6) in the weight n; the oil cup m is made with a long
boss m having a screwed thread on the outside, the weight k (see Fig. 4) being
tapped with a similar thread (see Figs. 3 and 6).
A locking ring o (see also detached views Fig. 5) is provided.
This ring is made with a downward projection ol and an inward projection o²;
the former (o) engages with one of a series of notches n' cut in the upper surface
of the weight n, and the latter (o²) engages in a vertical groove in the screwed
boss m'. The ring can thus be raised away from the weight n, when adjusting
the height of the oil cup m, and dropped down to prevent the screwed boss m¹
from turning when the proper height is attained, the projection o¹ engaging in one
of the notches n' before described.
The oil cup m is so set that the oil therein will be raised by the lifting rail up
to the boss p through which the spindle k works, the end of the said boss p dipping
into the oil when the rail is at its highest point (see Fig. 1). The lower part of
the space between the boss and the spindle k will be thus constantly filled with
oil and any vibration or jarring arising from any part being not perfectly balanced
will thus be prevented or softened.
The end of the dead spindle k is notched (see Figs. 3 and 7) and rests upon a pin
or peg m² driven through the boss m¹ near to the bottom thereof.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:
1. The general construction and arrangement of spinning mechanism substantially
as hereinbefore described and illustrated by the annexed drawings.
2. The means for driving the cup spindle c by a strap or tape at high velocities
as hereinbefore described.
"
3. The combination with the weighted tension lever of an inclined bush for
carrying the spindle of the tension pulley, and means for lubricating the said bush
and spindle substantially as herein before described and illustrated by the annexed
drawings.
4. The construction of the dead spindle substantially as herein set forth.
5. The combination with the dead spindle of an oil cup at the upper end thereof
for lubricating the bobbin spindle substantially as set forth and illustrated by the
annexed drawings.
6. The combination with the dead spindle and lifting rail of an oil cup (adjustable
as to its height) to prevent or soften jarring or vibration substantially as herein-
before set forth and illustrated by the accompanying drawings.
