PROVISIONAL SPECIFICATION left by the said John Speight at the
Office of the Commissioners of Patents, with his Petition, on the
29th November 1869.
I, JOHN SPEIGHT, of Bradford, in the County of York, Worsted
Spinner, do hereby declare the nature of the said Invention for "IMPROVE.
.MENTS IN MACHINERY OR APPARATUS FOR SPINNING, TWISTING, AND ROVING
WORSTED OR OTHER FIBROUS SUBSTANCES," to be as follows:-
The first part of this Invention relates to certain machinery for which
Letters Patent were granted to me dated October 9th 1867, wherein two
sets of spindles or studs are so arranged that whilst one set is in position
for spinning, twisting, or roving the other set is in position for doffing;
and the present improvements consist in the application of means for
Paice d

page_text: lapping or attaching the yarn to the empty bobbins when placed in
position and when the full ones are removed. For this purpose I
prefer to use bobbins formed with two flanges at the bottom end or
with a nick cut therein and a notch in one part thereof, and I mount
two slidcable rods underneath the lifter rail, each carrying a finger for
cach spindle or stud so arranged that when the change of sets is made a
slide motion is given to these two rods in contrary directions when the
fingers approach each other and press the yarn against the rotating
empty bobbins, the notches in which catch and lap or carry the same
around the bobbin.
Secondly. In means of cutting the yarn at such change of the sets of
spindles or studs, which consist in forming notches or serration's in the
front of the lifter rail, arranged one to each bobbin in a set for the yarns
to pass in contact with. Also in the application of a slidable bar
carrying a series of knives equal in number to the notches so arranged
that when slide motion is given thereto in the proper direction they will
close upon the notches with the yarn betwixt, and thereby cut the
same.
Thirdly. The Invention relates to means of giving rotary motion to
tubes working on fixed spindles or studs, which consist in the application
of toothed gear wheels for this purpose, by preference bevil wheels, but
other kinds may be adopted.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Speight in the Great Seal Patent Office on
the 27th May 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
SPEIGHT, of Bradford, in the County of York, Worsted Spinner, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-ninth day of November, in the
year of our Lord One thousand eight hundred and sixty-nine, in the
thirty-third year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said John Speight, Her special licence
that I, the said John Speight, my executors, administrators, and
assigns, or such others as I, the said John Speight, my executors,

page_text: administrators, and assigns, should at any time agree with, and no
others, from time to time and at all times thereafter during the term
therein expressed, should and lawfully might make, use, exercise, and
vend within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
MACHINERY OR APPARATUS FOR SPINNING. TWISTING, AND ROVING WORSTED OR
OTHER FIBROUS SUBSTANCES," upon the condition (amongst others) that I,
the said John Speight, my executors or administrators, by an instrument
in writing under my, or their, or one of their hands and seals, should
particularly describe and ascertain the nature of the said Invention,
and in what manner the same was to be performed, and cause the
same to be filed in the Great Scal Patent Office within six calendar
months next and immediately after the date of the said Letters
Patent.
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 accompanying Sheet of Drawings (that is
to say):-
The first part of this Invention relates to certain machinery for which
Letters Patent were granted to me dated the Ninth of October One
thousand eight hundred and sixty-seven, wherein two sets of spindles or
studs are so arranged that whilst one set is in position for spinning,
twisting, or roving the other set is in position for doffing; and the
present improvements consist in the application of means for lapping or
attaching the yarn to the empty bobbins when placed in position and
when the full ones are removed. For this purpose I prefer to use
bobbins formed with two flanges at the bottom end or with a nick cut
therein and a notch in one part thereof, and I mount two slideable rods
underneath the lifter rail, cach carrying a finger for each spindle or stud
so arranged that when the change of sets is made a slide motion is given
to these two rods in contrary directions when the fingers approach cach
other and press the yarn against the rotating empty bobbins, the notches
in which catch and lap or carry the same around the bobbins.
Secondly. In means of cutting the yarn at such changes of the setts
of spindles or studs, which consist in forming notches or seriations in the
front of the lifter rail arranged one to each bobbin in a set for. the yarns
to pass in contact with. Also in the application of a slideable bar

page_text: carrying a series of knives equal in number to the notches, so arranged
that when slide motion is given thereto in the proper direction they
will close upon the notches with the yarn betwixt, and thereby cut the
same.
Thirdly. The Invention relates to means of giving rotary motion to
tubes working on fixed spindles or studs, which consist in the application
of toothed gear wheels for this purpose, by preference bevel wheels, but
other kinds may be adopted.
My Invention will be better understood by reference to the accom-
panying Drawings:-
Fig. 1 is a part of the front elevation of a frame or machine for
spinning, twisting, and roving worsted or other fibrous substances
constructed after my method already patented and herein-before referred
to, and to which my present improvements are adapted; and Fig. 2 is
part of a vertical cross section of the same.
The parts marked A and B are respectively the two series of spindles
or studs fixed upon the shafts A' and B', which are geared and operated
in such manner that the spindles A. on which the full bobbins C are
represented, are lowered into the position B for doffing, while the
spindles B with the empty bobbins thercon are raised simultaneously
into the position of the spindles A for spinning, twisting, or doubling
each series, changing places alternately.
To separate or cut the thread or threads of one series of bobbins and
attach them to the other series rapidly and simultaneously by mechanical
means is the object of the first part of my Invention. It is for this
purpose I use bobbins formed with two flanges at the bottom, one of
which is notched (see Figs. 3 and 4, where the bobbins C and D are
shewn full size), and under the lifter rail there are two slide rods or bars
capable of sliding, with projecting fingers or lappers F and F', to which
motion is given in opposite directions. When the yarn or thread needs
to be lapped around or attached to the other series of bobbins the said
fingers approach each other, and pressing the yarn against and into the
groove of the rotating empty bobbins the notches F catch and lap or
carry the same around the said bobbins (see Figs. 5 and 6, which arc
represented full size). At the same time or a little after another slide
rod G carrying a series of knives or cutters G' press the yarn between or
against the notches H formed upon the front part of the lifter rail, and
cuts the threads or yarn of the series of bobbins which are turned down

page_text: or back for doffing, while at the same time the bobbins which are placed
in position for spinning or doubling have the yarn lapped around them
by means of the fingers F and F', as aforesaid. I are a series of bevel
pinions fixed upon the tubes which bear or carry the bobbins C and D
upon the spindles or studs A and B, and J are other bevel wheels fixed
upon a shaft K gearing into the pinions I. Rotary motion is given to
this shaft by any convenient means, and which motion is thereby com-
municated to the tubes and to the bobbins.
In Figs. 1 and 2 of these Drawings I have represented at L that class
of flyer which is known under the name of ring flyer, shewn in section,
full size, at Fig. 7, but I propose to employ also in certain cases in place
of these ring flyers such flyers as are shewn at Figs. 8 and 9. The body
of the flyer in this case is formed so as to rotate upon a bush N fixed
either upon the lifter rail or upon the guide rail of the frame. The body.
of this flyer M is formed into a wharle or pulley, and there is an annular
groove N¹ formed in the bush N to contain oil or other lubricant, in
which the bottom part of the flyer head rests, and is immersed in the
oil, which thereby keeps it always lubricated, and at the same time the
lower flange of the wharle effectually prevents dirt from getting in.
In Figs. 1 and 2 are also represented self-acting means or apparatus
which I employ in case of breakage of the yarn between the drawing
rollers P and the bobbins C or D to prevent the yarn continuing to pass
through or between the drawing rollers. S is a lever which is hinged
at T, and to one end of this lever two projecting fingers U are attached,
between which the yarn passes as it is delivered from the drawing rollers
to the bobbins, and at the other end of the said lever there is fixed a
knife or cutter V; this lever is arranged in such a manner that so long
as the yarn is unbroken it keeps the knife or cutter in the position shewn
in the Drawing, but should the yarn break between the drawing rollers
and the bobbins the end U falls and the knife or cutter V is raised into
contact with the plate or table W, when by the drag of the rollers P the
yarn is cut, and thereby is prevented from passing through the said
rollers. This apparatus is represented at Fig. 10 full size, but as it
does not form any part of this my said Invention I make no claim
to it.
Having thus described the nature of my said Invention, and shewn
by Drawings how or in what manner the same is to be or may be
nerformed or carried into practical operation, I would have it under-

page_text: stood that I do not claim the whole of the parts, nor do I confine or
restrict myself to the precise details of means or apparatus and arrange-
ments herein set forth; but what I claim as my said Invention, and
what I believe to be new is,-
Firstly. The means or method of lapping or attaching the yarns to
the empty bobbins simultaneously, as hercin described and shewn by
Drawings.
Secondly. The means or method of cutting the yarns asunder
simultaneously, as described and shewn by the Drawings.
Thirdly. The method of giving rotary motion to tubes when working
on fixed spindles or studs by toothed gear wheels.
In witness whereof, I, the said John Speight, have hereunto set my
hand and seal, this Twenty-sixth day of May, in the year of our
Lord One thousand eight hundred and seventy.
Signed, sealed, and delivered by the
within-named John Speight in
the presence of
