IMPROVEMENTS IN MACHINERY OR APPARATUS FOR SPINNING AND DOUBLING SILK, COTTON, AND OTHER FIBROUS PROVISIONAL SPECIFICATION
Year: 1860

page_text: LETTERS PATENT to Thomas Dickins, of Middleton, in the County of
Lancaster, Esquire, and Gilbert McCulloch, of Manchester, in the said
County, Mechanic, for the Invention of "IMPROVEMENTS IN MACHINERY OR
APPARATUS FOR SPINNING AND DOUBLING SILK, COTTON, AND OTHER FIBROUS
PROVISIONAL SPECIFICATION left by the said Thomas Dickins and
Gilbert McCulloch at the Office of the Commissioners of Patents, with
their Petition, on the 25th May 1860.
We, THOMAS DICKINS, of Middleton, in the County of Lancaster, Esquire,
and GILBERT MCCULLOCH, of Manchester, in the said County, Mechanic, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
MACHINERY OR APPARATUS FOR SPINNING AND DOUBLING SILK, COTTON, AND OTHER
FIBROUS MATERIALS," to be as follows:-
Our Invention relates to an arrangement whereby the flyer is dispensed
with, and the twist is obtained by a bobbin which revolves bodily, turning at
the same time upon its axis in order to effect the winding. The former of
these motions is gained by mounting the bobbin in brackets which are carried
by the spindle. For the latter, a worm wheel is carried round the spindle, which
wheel is in gear with a helical or spiral groove, so that as it is carried bodily
onward, it is caused to revolve slowly, and communicate rotary motion to a
pulley by means of a worm and pinion or other gearing; and the said pulley,
by means of a band, causes the bobbin to rotate. Or, in place of the pulley
and band, worms and worm wheels, or other gearing, may be adopted..

by the said Thomas Dickins and Gilbert McCulloch in the Great Seal
Patent Office on the 24th November 1860.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, THOMAS
DICKINS, of Middleton, in the County of Lancaster, Esquire, and GILBERT
MCCULLOCH, of Manchester, in the said County, Mechanic, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-fifth day of May, in the year of our Lord
One thousand eight hundred and sixty, in the twenty-third year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us, the
said Thomas Dickins and Gilbert McCulloch, Her special license that we,
the said Thomas Dickins and Gilbert McCulloch, our executors, adminis-
trators, and assigns, or such others as we, the said Thomas Dickins and
Gilbert McCulloch, our executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times there-
after 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 AND DOUBLING SILK, COTTON, AND OTHER
FIBROUS MATERIALS," upon the condition, amongst others, that we, the said
Thomas Dickins and Gilbert McCulloch, or one of us, by an instrument in
writing under our bands and seals, or under the hand and seal of one of us,
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 Thomas Dickins, do bereby declare
the nature of our 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 Drawings, that is to say:
Our Invention relates to an arrangement whereby the flyer is dispensed
with, and the twist obtained by a bobbin which revolves bodily, turning at the
same time upon its axis in order to effect the winding on.
In the accom-
panying Drawing the improvement is shewn in two views taken at right angles
to each other. The spindle is at a, turning at its lower end in a footstep
carried by a rail 6; the upper end is supported by a bush c fixed to a rail d, upon
which bush are formed spiral grooves e, constituting a worm. The upper end
of the spindle carries a bracket f, in which is mounted a shaft g, provided with

page_text: a toothed wheel h, taking into the spiral grooves of the worm e.
The shaft g
also carries a pulley i, around which a band passes, and from thence to
another pulley k formed upon the bobbin l, which bobbin turns in bearings
formed within the bracket f. Upon the shaft 9 is a worm m, in gear with
which is a pinion n mounted upon a shaft, which turns within a boss o, and
carrying at the opposite end to the pinion n, a crank pin p. This crank pin
is situate within a slot formed in a bell crauk q, q*, the part q* of which is a
wire extending upward, and provided with a curl at its end. Upon the
spinlle a is mounted a disc r, so connected as to revolve therewith by means
of a feather, but free to slide upward and downward. This disc rests upon the
edge of another dises mounted upon a line shaft t. The rails is provided
with slots, through which a handle u passes, which handle has an inclined part
capable of lifting the disc r by being drawn forward. The operation is as
follows:-Motion being communicated to the shaft t, the disc s will drive the
other r, and thus give rotatory motion to the spindle a. The bracket f being
by this means caused to revolve, will carry the pinion h around the inclined
grooves of the worm e, by which means rotatory motion will be given to
shaft g, and from thence through the pullies i, k, to the bobbin l. The shaft
by thus revolving will at the same time give motion to the pinion n through
the worm m, and the crank pin p being thus caused to rotate, will turn the
bell-crank q, q, upon its centre, so as to cause the curl q* through which the
material passes to traverse, and thus distribute the thread upon the bobbin.
When it is desired to arrest the motion of the spindle, the handle u is drawn
forward, and the incline thereon will lift the disc r from the driving power.
We have in the above alluded to a particular method of driving the spindle,
but we do not confine ourselves thereto, as that operation may be effected by
any of the usual methods.
Having thus described and ascertained the nature of our said Invention,
and the manner of carrying the same into effect, we desire it to be understood
that we claim as secured to us under the above in part recited Letters Patent,
the use of the pinion h moving around a worm or inclined groove, for the
purposes aforesaid.
In witness whereof, I, the said Thomas Dickins, have hereunto set my
hand and seal, this Twenty-third day of November, in the year of
our Lord One thousand eight hundred and sixty.
THO. DICKINS.
