Year: 1867

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
BSO ARAME THE DODDING "
Sealed the 4th April 1868, and dated the 9th October 1867.
PROVISIONAL SPECIFICATION left by the said John Speight at the
Office of the Commissioners of Patents, with his Petition, on the
9th October 1867.
I, JOHN SPEIGHT, of Bradford, in the County of York, Worsted Spinner,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
MACHINERY OR APPARATUS FOR SPINNING, TWISTING, AND ROVING WORSTED OR
OTHER FIBROUS SUBSTANCES TO FACILITATE THE DOPPING," to be as follows:-
This Invention relates to that class of machinery or apparatus for spinning,
twisting, or roving known as "throstle frames and "cap frames, and my
improvements consist in the employment of duplicate spindles or bobbins,
that is, in having two sets of spindles or studs so arranged that while one set
is in position for spinning, twisting, and roving the other set is in position for
doffing. Each set according to one method is mounted on a shaft capable
of turning on its axis and also sliding endwise, such shafts being placed
and operated so that each set of spindles or studs may change position
alternately, or as and when required, or other methods may be adopted of
applying duplicate spindles or studs.
In carrying out this Invention I either employ flyers suspended by their
necks to a rail over the spindles or studs in which they are capable of rotating,
or I use wharks or whiris constructed so as to be capable of rotating in

page_text: bearings formed in the lifter rails and traversed up and down thereby. A
guide eye is fixed in each wharle or whirle, and a central hole is formed
therein of sufficient diameter to allow the bobbin when filled with the spun
yarn to pass through it. When employing flyers I form a cup or cavity
over each end, and attached to the rail, to contain oil or other lubricant.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Speight in the Great Seal Patent Office on the
9th April 1868.
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 Ninth day of October, in the year of our Lord
One thousand eight hundred and sixty-seven, in the thirty-first 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, 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 TO FACILITATE THE DOFFING," upon the condition (amongst others)
that I, the said John Speight, my executors or administrators, by an instru-
ment 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 Seal 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 thereof and accompanying Sheet of Drawings (that is to say):
This Invention relates to that class of machinery or apparatus for spinning,
twisting, or roving known as throstle frames and cap frames, and my
0

page_text: improvements consist in the employment of duplicate spindles or bobbin studs,
that is, in having two sets of spindles or studs so arranged that while one set
is in position for spinning, twisting, and roving, the other set is in position for
doffing. Each set according to one method is mounted on a shaft capable
of turning on its axis and also of sliding endwise, such shafts being placed and
operated so as that each set of spindles or studs may change position alternately,
or as and when required, or other methods may be adopted of applying
duplicate spindles or studs.
In carrying out this Invention I either employ flyers suspended by their
necks to a rail over the spindles or studs in which they are capable of rotating,
or I use wharles or whirls constructed so as to be capable of rotating in
bearings formed in the lifter rails and traversed up and down thereby. A
guide eye is fixed in each wharle or whirl, and a central hole is formed therein
of sufficient diameter to allow the bobbin when filled with the spun or twisted
yarn to pass through it. When employing flyers I form a cup or cavity over
or in each flyer neck to fit a suspending boss or socket attached to the rail to
contain oil or other lubricant.
In order that this Invention may be clearly understood, I herein give
reference to an accompanying Sheet of Drawings of an ordinary worsted
spinning frame with my improvements applied thereto..
DESCRIPTION OF THE DRAWINGS.
Fig. 1 is a front elevation, and Fig. 2 is a cross section of the same taken
through the line A, B, in Fig. 1. In these Drawings I have shewn the
application of flyers specially constructed for carrying out this Invention;
these flyers marked C are suspended by their necks to a rail D fixed to the
ordinary top rail of the frame Ẹ. One set or series of the spindles or bobbin
studs Fare fixed on a shaft F, which is mounted in brackets F attached to
the ordinary lifter rail G; another set or series of spindles or bobbin studs H
are in like manner fixed to another shaft H', which is also mounted in the
said brackets F. These shafts are geared together by spur wheels I, and are
coupled by a double collar or link 1'; a lever handle J is fixed on the shaft
F, which passes through an oblique slot hole in a plate K fixed to the frame.
The set of studs F are shewn with the tubes a and bobbins or spools 6 thereon
and in proper position for the spinning process and for the yarn to be wound upon
them by the flyer in the usual manner, while the other set H are shewn
without the bobbins and placed out of position for the spinning process, but in
a suitable position to bavo the full bobbins doffed or removed therefrom and
empty bobbins placed thereon ready for the spinning, and winding the spun

page_text: yarn upon them. It will be readily seen that if the lever handle J be pressed
downward it will move in the slot and thereby turn both the shafts F¹ and H'
in opposite directions to each other, and also move them end wise, so that the
two sets of studs will change positions or places, or that the studs F will be
removed out of position for spinning and winding the spun yarn on the bobbins
but into position for doffing, and that simultaneously therewith the studs H
will be placed in position for spinning and winding the spun yarn on the
bobbins. A spring catch J' is attached to the handle J, which takes into a
notch plate J on the slot plate K for placing and holding the studs in proper
or true position. Rotary motion is communicated to the flyers from an
ordinary roller L by straps or bands L' acting on pullies or whirls L² fixed or
formed on the flyers. The tubes a, on which the bobbins or spools bare placed,
have rotary motion given to them by frictional contact with a strap M, which
is mounted on pullies fixed on upright shafts M and M, the latter of which
shafts being driven by a belt from a roller N. Fig. 3 is a full sized sectional
view of the flyer and the rail in which it is suspended and rotates, shewing its
peculiar construction and the method of suspension and the provision made
for the lubrication thereof, and also the bobbin studs and their shafts, one
of said studs having a spool bobbin thereon in proper form.
Figs. 4 and 5 shew full size the construction and method of applying wharles
or whirls to be used instead of flyers. P is the said wharle or whirl; and
Qthe rail in which it is suspended and in which it is capable of rotating,
the hole in the whirl being of suitable diameter to allow the spool when full of
yarn to pass through it, the tweezles p carrying the yarn around the bobbins
in the same manner as flyers do.
In witness whereof, I, the said John Speight, have hereunto set my
hand and seal, this Sixth day of April, One thousand eight hundred and
sirte-night
JOHN SPEIGHT. (L.S.)
