Year: 1858

page_text: LETTERS PATENT to John Platt, of Oldham, in the County of Lancaster,
Mechanical Engineer, for the Invention of "IMPROVEMENTS IN MACHINERY
OR APPARATUS FOR SPINNING AND DOUBLING OR TWINING COTTON AND OTHER
FIBROUS MATERIALS."
Sealed the 2nd July 1858, and dated the 5th January 1858.
PROVISIONAL SPECIFICATION left by the said John Platt at the Office
of the Commissioners of Patents, with his Petition, on the 5th
January 1858.
I, JOHN PLATT, of Oldham, in the County of Lancaster, Mechanical
Engineer, do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN MACHINERY OR APPARATUS FOR SPINNING AND DOUBLING OR TWINING COTTON AND
OTHER FIBROUS MATERIALS," to be as follows:-
The first part of this Invention relates to a method of driving the tin drum
of the mule, and consists in adapting thereto a force exerted in opposite direc-
tions, so that the said drum becomes as it were suspended; and to accomplish
this I arrange the driving band or bands on the drum so that it or they will
pass on either side thereof, a suitable distribution of guide pullies being pro-
vided for the purpose.
The second part of the Invention consists in the adaptation of the apparatus
termed in mules the "quadrant," for regulating the winding on to the
"twining jenny;" also in the said machine I cause the chain which proceeds
from the slide to pass over a pulley or equivalent apparatus connected to the
nut of the regulating screw and from thence to the drum.

by the said John Platt, in the Great Seal Patent Office on the
5th July 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
PLATT, of Oldham, in the County of Lancaster, Mechanical Engineer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fifth day of Jauuáry, in the year of our Lord One
thousand eight hundred and fifty-eight, in the twenty-first year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said John Platt, Her especial license that I, the said John Platt, my]
executors, administrators, and assigns, or such others as I, the said John
Platt, 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 AND DOUBLING OR TWINING COTTON AND
OTHER FIBROUS MATERIALS," upon the condition, aniongst others, that I, the
said John Platt, by an instrument in writing under my hand and seal, 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 imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said John Platt, do hereby declare the
nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement and accompanying Drawings (that is to say):-
The first part of this invention relates to a method of driving the "tin
drum" of the "mule," and consists in adapting thereto a force exerted in
opposite directions, so that the said drum becomes as it were suspended; and
to accomplish this I arrange the 'driving band or bands on the drum so that
it or they will pass on either side thereof, a suitable distribution of guide
pullies being provided for the purpose.
The second part of the Invention consists in the adaption of the apparatus
termed in mules the quadrant," for regulating the winding on to the
"twining jenny," and in the said machine. I. cause the chain which proceeds

page_text: from the "slide," to pass over a pulley or equivalent apparatus connected to
the nut of the." regulating screw" and from thence to the drum.
Having thus stated the general features of my Invention, I will proceed to.
point out how the same may be carried into practical operation.
The first improvement is shewn in the isometrical perspective view, Fig. 1;.
which represents so much of a mule as is necessary to explain the method of
driving the spindles. The rim wheel is shewn at a, the tin drúm at b and c ;.
d, e, f, g, are guide pullies; the course of the driving band over these is as
follows-Starting from the point A it passes, as indicated by the arrow, over
the guide pulley c, and from thence around the tin drum 6 back to the guide
pulley d, from thence it passes direct to the underside of the pulley e, and
having gained the upper side thereof, passes around the tin drum 6 on the
opposite side to that which it previously traversed, but driving it in the same
direction; after this it proceeds over the guide pulley f, over another guide:
pulley g, and from thence to the rim wheel a. It will be perceived that by
this arrangement the driving power is exerted in opposite directions, and that
the drag, therefore, upon one side of the bearings is avoided.
The second part of the Invention is shewn at Fig. 2, which represents a
portion of a twining jenny constructed for adaptation to the self-acting principle.
The headstock may be of that arrangement for which Letters Patent were
granted to me, bearing date the Second day of December, One thousand eight
hundred and fifty, or of other construction, and I have in the accompanying
Drawing exhibited those parts only connected with my present Invention.
The slide or moveable creel is shewn at a, to each side of which is adapted a
cord b, capable of adjustment by means of the ratchet wheels c. This cord
passes over guide pullies d, and from thence around a pulley e, upon the axis
of which is a pinion f, taking into the teeth of the quadrant g, formed upon the
arm or lever h, which carries the regulating screw i. The usual nut of this
screw is shewn at k; but it is in this instance provided with a pulley 1, over
which the winding-on chain m passes, one end thereof being attached to the
slide or moveable creel at n, and the other being connected to the winding-on
drum o.
As the slide or creel moves to-and-fro it communicates motion by
means of the cord 6 to the pulley e, and thus, by the pinion f, the quadrant g
and regulating screw i are caused to perform their necessary vibratory motion
and to govern the winding-on through the chain m, as is well understood, the
pulley being moved with the nut as usual in the self-acting mule.
Having thus described and ascertained the nature of my said Invention,
and the manner of carrying the same into effect, I desire it to be understood
that I claim as secured to me under the above in part recited Letters Patent,

page_text: Firstly, in reference to mules, the method of driving the "tin drum" or tin
"roller," whereby it is drawn in opposite directions, and becomes as it were
suspended or balanced..
Secondly, in reference to machinery for doubling or twining, and "known as
the twining jenny, the application of the apparatus termed in mules the
"quadrant," for regulating the winding-on; also, in reference to the same
machinery, I claim the application to the nut of the regulating screw of a
pulley or equivalent apparatus for carrying the winding-on chain.
In witness whereof, I, the said John Platt, have hereunto set my hand
and seal, this Second day of July, in the year of our Lord One
thousand eight hundred and fifty-eight.
