Year: 1870

page_text: LETTERS PATENT to John Speight, of Bradford, in the County of
York, Worsted Spinner, for the Invention of "IMPROVEMENTS IN
MACHINERY OR APPARATUS FOR SPINNING, TWISTING, AND ROVING WORSTED
OR OTHER FIBROUS SUBSTANCES."
Sealed the 8th November 1870, and dated the 9th May 1870.
PROVISIONAL SPECIFICATION filed by the said John Speight at the
Office of the Commissioners of Patents, with his Petition, on the
9th May 1870.
I, JOHN SPEIGHT, of Bradford, in the County of York, Worsted
Spinner, do hereby declare the nature of the said Invention for "IM-
PROVEMENTS IN MACHINERY OR Apparatus for Spinning, Twisting, and Roving
WORSTED OR OTHER Fibrous SubstANCES,” to be as follows :—
One part of this Invention relates to means or apparatus for simul-
taneously lapping the ends of yarn around the empty bobbins when'
the full ones are doffed or removed, and consists in the employment of a
series (one to each bobbin) of bosses, rings, or collars with projecting
fingers mounted in the lifter rail, and geared together so as to be
capable of rotating in the proper direction, the bobbins being so
arranged as to traverse through them, or the bosses may be formed
into wharles, and in such case I use cylinders or rollers and bands to

page_text: give motion to the said bosses similar to the usual method of driving
spindles of spinning frames. When motion is given to the bosses, rings,
or collars the fingers catch the ends of the yarn and lap or turn them
around the bobbins, and then the motion of the bosses, rings, or collars
ceases and the bobbins are caused to rotate in the usual manner, or as
herein-after described.
Another part of my Invention relates to an improved mode of doffing
in either cap or flyer frames, and consists in means of removing a series
of caps or flyers simultaneously. For this purpose I prefer to employ
those caps which have respectively a flange around the exterior surface
intermediately in the length thereof, and I employ bosses constructed
as above referred to of suitable size for the bottom part of the said caps
to pass through and for the flanges to rest upon. The lifter rail I
arrange and operate so as to be lifted clear above the cap studs with the
caps resting thereon, and enable the full bobbins to be doffed and empty
ones substituted; the lifter rail is then lowered and the caps are
replaced on their studs ready for work again. For flyer frames I have
the openings in the bosses large enough for the flyer to pass through,
and I apply one or more sliding rods to the lifter rail, which are capable
of passing under the head of the flyer, and which when the rail is lifted
will lift the flyers off their spindles in a similar manner to the caps, and
when the rail is lowered will replace them on the spindles.
Another part of the said Invention relates to means of driving tubes
or bobbins, and also dispensing with lifter rails, and consists in having
the bottom or flange of the said tubes or bobbins formed to fit within
concentric grooves in the sides of discs fixed on a horizontal shaft which
is both capable of rotating and also. of. being lifted and lowered, so that
the discs give rotary motion to the tubes by frictional contact, and the
said tubes or bobbins are also traversed by the lifting and lowering of
the shaft.

NOW KNOW YE, that I, the said John Speight, do hereby declare
the nature of my said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by
the following statement, and the two accompanying Sheets of Drawings
(that is to say)
One part of this Invention relates to means or apparatus for simul-
taneously lapping the ends of yarn around the empty bobbins when the
full ones are doffed or removed, and consists in the employment of a
series (one to each bobbin) of bosses, rings, or collars, with projecting
› fingers mounted in the lifter rail and geared together so as to be capable
of rotating in the proper direction, the bobbins being so arranged as to
traverse through them, or the bosses may be formed into wharles, and
in such case I use cylinders or rollers and bands to give motion to the
said bosses similar to the usual method of driving spindles of spinning
5 frames. When motion is given to the bosses, rings, or collars, the
fingers catch the ends of the yarn and lap or turn them around, the
bobbins, and then the motion of the bosses,, rings, or collars ceases and

page_text: the bobbins are caused to rotate in the usual manner or as herein-after
described.
Another part of my Invention relates to an improved mode of doffing
in either cap or flyer frames, and consists in means of removing a series
of caps or flyers simultaneously. For this purpose I prefer to employ
those caps which have respectively a flange around the exterior surface
intermediately in the length thereof, and I employ bosses constructed'
as above referred to of suitable size for the bottom part of the said caps
to pass through and for the flanges to rest upon. The lifter rail I
arrange and operate so as to be lifted clear above the cap studs with the 1
caps resting thereon, and enable the full bobbins to be doffed and
empty onès substituted; the lifter rail is then lowered and the caps
are replaced on their studs ready for work again. For flyer frames I
have the openings in the bosscs large enough for the flyer to pass
through, and I apply one or more sliding rods to the lifter rail, which 1
are capable of passing under the head of the flyer, and which when the
rail is lifted will lift the flyers off their spindles in a similar manner to
the caps, and when the rail is lowered will replace them on the
spindles.
Another part of the said Invention relates to means of driving tubes 2
or bobbins, and also dispensing with lifter rails, and consists in having
the bottom or flange of the said tubes or bobbins formed to fit within
concentric grooves in the sides of discs fixed on a horizontal shaft,
which is both capable of rotating, and also of being lifted and lowered,
so that the discs give rotary motion to the tubes by frictional contact, 2
and the said tubes or bobbins are also traversed by the lifting and
lowering of the shaft.
In order that the Invention may be fully understood I herein give
Fig. 1 is part of the front elevation of an ordinary spinning frame
with my improvements applied thereto, and Fig. 2 is part of an end
elevation of the same.
The ordinary spinning frame being so well known I have not deemed
it necessary to shew the whole of the parts thereof, but only such as are 3
requisite to shew the application of these improvements.

page_text: The first part is shewn as follows:-A are the bosses, rings, or collars,
with projecting fingers a mounted in the lifter rail B, and which may
be either constructed and applied so as to rotate in the said rail, or they
may be fixed therein, the finger a being fixed in a ring or collar capable
of rotating on the boss, as here shewn, and this ring or collar may be
cither formed into a toothed wheel or into a wharle or pulley for tho
purpose of receiving rotary motion. If formed into a toothed wheel
then the whole series of them on one side of the frame are geared
together by intermediates, so as that motion may be given in the proper
direction to the whole train at the same time from one end of the frame.
If formed into a wharle or pulley then I mount a roller C on brackets
fixed to the lifter rail, so as to be carried up and down thereby, and by
having bands passing around the same and the series of wharles or
pulleys. I give motion to them by turning the said roller C. This is
shewn full size at Fig. 3. This part of my said Invention is more par-
ticularly applicable where two sets or series of spindles or bobbin studs
are employed, as shewn at D and E, and for which Letters Patent were
granted to me, dated the Ninth day of October 1867, and numbered
2841. In the Specification of which Patent it is shewn and explained,
that while one set or series of spindles are in position for spinning the
other are in position for doffing, also that the yarn is severed by knives
as shewn in these present Drawings at F, the ends of the said yarn aro
then pressed against the bobbins by sliding fingers and caught by
notches in the bottom flanges of the bobbins or tubes, which by their
rotation lap the said ends of yarn around the empty bobbins. These
rotary bosses, rings, or collars with fingers are therefore to be or may
be used instead or in substitution of the sliding fingers above referred
to, the said sliding fingers however being equally applicable and
advantageously useful for the purpose.
.
The second part of this Invention, the mechanical means of doffing
cither caps or flyers simultaneously is shown in these Drawings, whercin
G are the caps, which for this purpose have each a flange G' inter-
mediately or about their middle, as shewn full size at Fig. 4, and the
lifter rail is constructed so that the bottom part of the cap will pass
through it, and the flange will rest upon the said rail, and thus by the
lifting of the said rail the caps will be lifted-off their studs. In this
caso the lifter rail is not used for the ordinary purpose of traversing the
yarn on the bobbins, but simply for the purpose of doffing or for lifting
the caps off their studs when about to doff, or remove the full bobbins.

page_text: of
and place empty ones thereon. For this purpose I employ a series of
pulleys H fixed on a shaft H', on which is also fixed a handle I, and to
the said pullies are attached chains or cords connected to slide rods J,
which are fixed to the said lifter rail. By operating the handle in one
direction the lifter rail will be raised, and thereby lift the whole series 5
caps off their respective studs, and by turning the handle in the other
direction the said rail will be lowered, and thereby replace the said caps
on their studs. In the case of flyers a similar arrangement of lifter rail
is used, but so constructed that the flyers can pass through it, and I
employ a slide bar with fingers, as shewn at Fig. 5, which when the 1
flyers are required to be lifted off their spindles the rail is placed in
suitable position, so that on the slide bar being moved endways the
fingers will be passed under the heads of the flyers, and consequently
by lifting the rail, as herein-before explained the said flyers will also
be lifted off their respective spindles, and by lowering it they will be 1
again replaced in a similar manner as with the caps.
The third part of this Invention, being the means of driving tubes or
bobbins by friction and the dispensing with lifter rails, is also shewn
in these Drawings, where K are the bottom flanges of the tubes or
bobbins which fit within concentric grooves formed in discs L fixed 2
on a horizontal shaft M, which is not only capable of rotating so as to
give rotary motion to the tubes or bobbins by frictional contact, but is
capable of being raised and lowered, and thereby capable of raising and
lowering the said tubes or bobbins.
The operation is as follows:-When rotary motion is given to the 2
shaft M in any convenient manner, such motion will be communicated
to the tubes or bobbins by the discs, as will be readily seen, and motion
is communicated from the drawing rollers N by means of strap and
pullies O and P, worm and wheel Q, shaft R, and worm and wheel S, to
the cam or tappet T, which operating upon the lever U gives oscillatory 3
motion to the segment wheels V, which gearing in racks W capable of
moving up and down on the rods ✗ gives a rising and falling or a
traversing motion to the shaft M, so that rotary motion is given to the
tubes or bobbins, and they are also traversed by the combined motious
or operations of the said shaft M.
Sometimes I traverse tubes or bobbins by ordinary means, and in
I do not turn on mice this viving and falling motion to the

friction disc L.
Fig. 7 is an end elevation of the frame shewing the method or
means of driving the shaft M by cords Y and Y from the double
pulley Z.
Having thus described the nature of the said Invention, and shewn
by Drawings and description the manner in which the same is or may
be performed or put into practical operation, I would have it understood
that what I claim as of my Invention is,―
Firstly. The means or method of lapping or attaching the ends of
yarn to the empty bobbins simultaneously, as shewn and described.
Secondly. The method or means, substantially as shewn and described,
for lifting caps and flyers simultaneously from their studs or spindles for
the purpose of doffing the bobbins.
Thirdly. The method of driving or giving rotary motion to tubes or
bobbins by friction, as shown and described, whether the driving shaft
be traversed or not.
Fourthly. The method of traversing tubes or bobbins by giving a
traverse motion to the driving shaft, as shewn by the Drawings and
herein described.
In witness whereof, I, the said John Speight, have hereunto set my
hand and seal, this Eighth day of November, in the year of. our
Lord One thousand eight hundred and seventy.
