page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, OTTO
ROTTON, of Gracechurch Street, in the City of London, Doctor of Medicine,
send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Royal Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Twenty-sixth day of April, in the fifth year of Her reign,
did, for Herself, Her heirs, and successors, give and grant unto me, the said
Otto Rotton, Her especial licence, full power, sole privilege and authority,
that I, the said Otto Rotton, my executors, administrators, and assigns, and
such others, as I, the said Otto Rotton, my executors, administrators, or,
assigns, should at any time agree with, and no others, from time to time and
at all times during the term of years therein mentioned, should and lawfully
might make, exercise, and vend, within England, Wales, and Town of
Berwick-upon-Tweed, and in all Her Majesty's Colonies and Plantations
abroad, and in the Islands of Jersey, Guernsey, Alderney, Sark, and Man, an
Invention of "CERTAIN IMPROVEMENTS IN MACHINERY OR APPARATUS FOR SPIN-
NING COTTON, WOOL, SILK, AND OTHER FIBROUS SUBSTANCES," being a communi-
cation from a foreigner residing abroad; in which said Letters Patent is
contained a proviso, obliging me, the said Otto Rotton, by an instrument in
writing under my hand and seal, particularly to describe and ascertain the
nature of the said Invention, and in what manner the same is to be performed,
and to cause the same to be inrolled in Her Majesty's High Court of Chancery
within six calendar months next and immediately after the date of the said in
part recited Letters Patent, as in and by the same, reference being thereunto
had, will more fully and at large appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
Otto Rotton, do hereby declare that the nature of the said Invention, and the
manner in which the same is to be performed, are particularly described and
ascertained in and by the following description thereof, reference being had to
the Drawings hereunto annexed, and to the letters and figures marked thereon
(that is to say):
This Invention of improvements in machinery or apparatus for spinning
cotton, wool, silk, and other fibrous substances, consists in a peculiar com-
bination or arrangement of machinery constituting what is commonly called a
throstle, such arrangement having the bobbins, spindles, and flyers disposed in
a circular range, in contradistinction to the ordinary arrangement, according to
which those parts are situated in right lines; this disposition of the parts
permitting the use of the peculiar feature of this Invention, which consists in
a mode of, driving the bobbins, spindles, or flyers of spinning machinery by
means of friction through the intervention of a bevelled-edged horizontal
wheel, without the assistance of bands and riggers.
In the accompanying Drawings, Fig. 1 represents a side elevation of the im-
proved arrangement of the throstle; Fig. 2, a horizontal view of the same, as
seen from above; Fig. 3, a vertical section, taken about the line a, b, in Fig. 2,
looking towards the left-hand end thereof; and Fig. 4 is a horizontal section,
shewing the lower part of the machine, taken through the line c, d, in Fig. 3;
in all of which Figures similar letters denote the same parts. The spindles,
flyers, and bobbins used in this machine are nearly the same as some commonly
employed, but a slight difference exists, which I will now point out. Fig. 5 repre-
sents one of the spindles with its bobbin, in vertical section. The spindles a, a,
when affixed to the machine, are intended to be stationary, and each provided
with a cylindrical cavity in its upper end, which receives the rotary spindle b, b;
upon this the flyer c, c, is screwed, the spindle 6 being provided with a shoulder
d, which bears upon the top edge of the stationary spindle a, a. The bobbin
shewn at e, e, is placed loosely upon the spindle a, a, and is capable of revolving
freely thereon; it is of the usual construction, with the exception of the bottom
flange e, e, which is here formed as the frustrum of a cone, for the purpose
herein-after described, which frustrum of a cone may be made of any suitable
material. The spindles, bobbins, and flyers thus constructed are mounted upon
the large circular rail f,f.f, (as shewn at Figures 1 and 3,) the spindles a, a, a,
being firmly secured to the rail f,f,f,f, by screws, as represented in the
Drawing. The roller stands or brackets j,j,j, which carry the drawing rollers
i, i, i, are affixed to an upper polygonal rail or plate h, h, that plate being sup-
ported by arms 9, 9, extending upwards from the circular rail f. The front and

page_text: second rollers i, i, i, turning in the roller stands or brackets j, j,j, are arranged
in this Figure in pairs, and disposed in a polygonal form, as shewn in Fig. 2,
in order to accommodate them to the circular arrangement of bobbins and
flyers upon the circular rail f,f. A frame k, k, k, k, above is attached to the
roller plate h, h, parts of which are capable of turning upon hinges in segments,
corresponding to each set of rollers, in order to admit of doffing. To each of
these segments are affixed a series of eyes or thread guides m, m; another
frame of wood n, n, n, is also mounted upon the roller plate h, h, h, within the
circle of rollers, for the purpose of supporting the creel, as shewn at 0, 0, 0,
which creel is provided with eyes or staples to receive the tops of the creel
axles p, p, upon which the material to be spun is wound in cops; the lower
end of those creel axles turn in sockets or steps set in the frame n, n, n. The
lower conical flanges e* of the bobbins e, e, e, bear against the wheel or disc
99, 9.9, fixed on the vertical shaft r, which wheel or disc is shewn in the
Drawings to be conical on its upper surface, and corresponding to the bevelled
ends of the bobbin flanges e*, e, e*. The vertical shaft r, carrying the disc or
wheel q, is capable of being moved up and down by the action of a lever M,
which supports it below. Motion is communicated to the mechanism by the
following ineans:-The horizontal or main driving shaft s, s, (in Figs. 1 and 4).
is provided with the usual fast and loose pullies, to be driven by a band from
any first mover. On the inner extremity of this shaft s is affixed the bevelled
wheel t, t, which takes into another bevelled wheel u, turning loosely in a
bracket v, which pinion u is connected to the vertical shaft r by a rib or key,
allowing the shaft to slide up through it, and hence the shaft r is turned round
as the pinion u revolves. By these means rotary motion is communicated
from the horizontal shaft s to the vertical shaft r, and to the wheel or disc q, q.
affixed to about the middle of that shaft by a socket; this wheel or disc in
revolving turns the bobbins e, e, e, round upon their spindles, by the friction of
contact between the flanges e*, e*, e*, and the periphery of the disc or wheel
99,9; in the centre of the plate h a socket y is affixed, in which socket a
bevel pinion is inserted, turning loosely, and this pinion is connected to the
upper end of the shaft r by a rib or key, so that the pinion shall be turned by
the rotation of the vertical shaft, which slides through it. The wheel x, at the
top of the shaft r, gears into a wheel w, affixed to the inner end of an upper
horizontal shaft z, (seen best in Fig. 2.) At the outer extremity of this shaft
z there is a bevelled wheel A, taking into the wheel B on the tangent shaft C,
upon which shaft are also mounted bevelled wheels D, D, driving correspond-
ing wheels on the ends of the front drawing rollers i, i; the two inner tiers
,,, of drawing rollers are driven at a suitable speed by means of the

page_text: ordinary gear shewn in the Drawings. Rotary motion is thus communicated
to the first set of rollers at each end of the tangent shaft C, and by means of
teeth cut in the ends of the rollers, corresponding motion is communicated to
the remaining bottom rollers in the series. The copping motion which I have
employed is effected by the following means:-Upon the main driving shaft
8, s, is affixed the worm or endless screw E, taking into the worm wheel F,
(see Figs: 1 and 4,) which worm wheel is mounted upon a tangent shaft G.
At the reverse end of this shaft G is a worm H (shewn by dots in Fig. 4),
taking into the worm wheel I (seen by dots in Figs. 1 and 4) affixed to
the shaft J (seen in dots in Fig. 4, and in section in Fig. 3). Upon this
shaft J is also affixed the heart wheel K, which in revolving, by means of
the train of gear above described, operates upon the roller L, on a stud in the
lever M, vibrating upon a fulcrum in the stationary standard (shewn in Fig. 3).
The lever M will thus be caused to rise and fall upon its fulcrum, and by so
doing to lift the vertical shaft r, r, which bears upon the end of its shorter
arm. The shaft r, r, with the horizontal wheel or disc q, q, is raised and
suffered to descend by the action of the heart wheel K, and the bobbins being
supported by the wheel or dise q, q, rise and fall with it, and thus effect the
copping of the yarn.
I have in my Specification described the manner of driving bobbins only by
this newly-invented niethod, as it will be obvious to any competent workman
how to apply this Invention to drive the flyers and spindles; the application of
more than one wheel to drive another set of bobbins. above the first must be
equally obvious.
In witness whereof, I, the said Otto Rotton, have hereunto set my hand
and seal, this Fourth day of August, in the year of our Lord One
thousand eight hundred and forty-two.
OTTO ROTTON. (L.S.)
AND BE IT REMEMBERED, that on the same Fourth day of August,
in the year above mentioned, the aforesaid Otto Rotton came before our Lady
the Queen in Her Chancery, and acknowledged the Specification aforesaid, and
all and every thing therein contained, in form above written. And also the
Specification aforesaid was stamped according to the tenor of the Statute in
that case made and provided.
