IMPROVEMENTS IN MULES FOR SPINNING AND DOUBLING
Year: 1865

page_text: LETTERS PATENT to John Dodd, of Oldham, in the County of Lancaster,
Mechanical Engineer, for the Invention of "IMPROVEMENTS IN MULES FOR
SPINNING AND DOUBLING."
Sealed the 19th September 1865, and dated the 25th March 1865.
PROVISIONAL SPECIFICATION left by the said John Dodd at the Office
of the Commissioners of Patents, with his Petition, on the 25th March
1865.
I, JOHN DODD, of Oldham, in the County of Lancaster, Mechanical
Engineer, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN MULES POR SPINNING AND DOUBLING," to be as follows:-
The first part of my Invention relates to a combination of parts by which
the "nut" of the "winding-on screw" is made self-acting. For this purpose
I form the said screw variable in pitch, and connect it for the necessary
regulation to the ordinary faller, "star plate," and endless band arrangement
of the governor.
The second part of my Invention consists in mounting the "star plate" on
a lever which is connected to the faller, whereby the said "star plate" is
caused to rise with the faller during the inward run of the carriage, whereby
the "counterfaller" can put the "governor " into action by the same amount
of deviation from its proper winding position at any part of the inward run of
the carriage.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
DODD, 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 Twenty-fifth day of March, in the year of our Lord
One thousand eight hundred and sixty-five, in the twenty-eighth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said John Dodd, Her special licence that I, the said John Dodd, my
executors, administrators, and assigns, or such others as I, the said John
Dodd, 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 MULES FOR
SPINNING AND DOUBLING," upon the condition, amongst others, that I, the said
John Dodd, 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
immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said John Dodd, 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 Drawings, that is to say:-
My Invention relates to a combination of parts by which the nut of the
"winding-on screw" is made self-acting. For this purpose I form the said screw
variable in pitch, and connect it for the necessary regulation to the ordinary
faller, star plate, and endless band arrangement of the governor.
'
Figure 1 represents a side elevation of the winding-on apparatus of a mule
and parts connected therewith, and Figure 2 a detached view of the winding-on
screw I employ. This form of screw I do not claim as my Invention, but have
shewn and will now describe it for the purpose of explaining the combination
I claim. The screw is shewn at a, formed with a thread upon it of varying pitch,
the end-a¹ being the quicker, and intended to be used at the commencement of
the cop; while the end a³ is much slower in pitch, and is designed for use

page_text: when the cop is in an advanced state. The nut for this screw, and which is
mounted in the quadrant after the usual manner, is shewn at b. It consists
of a block with a smooth socket bored through it equal in diameter to the
outward circumference of the screw. In this block is formed a chamber c,
within which is placed a cylindrical piece with a projecting part as seen
detached at d; the said projecting part, when adapted, extending into the
thread of the screw. When therefore the said screw is caused to revolve the
cylindrical piece can turn upon its centre so as to accommodate the projecting
part to the varying pitch of the screw. The screw thus constructed is placed
in the quadrant after the usual manner of regulating screws, and upon its axis
is mounted a bevil pinion e taking into another, on the axis of which is a
pulley carrying the ordinary winding-on band g. At h is the star wheel,
which, together with the drum i, is mounted loosely upon the axis k. The
faller and counterfaller shafts are shewn at l, m, upon the former of which is
mounted an arm n, to this and to the counterfaller is attached a chain o,
which supports the ordinary lever p, turning upon a centre 9 attached to the
carriage. When the counterfaller is depressed the chain o allows the lever p
to descend, and brings a stud r projecting therefrom in contact with the star
wheel, which being thus held fast causes the travelling of the carriage to turn
the regulating screw through the medium of the band g, as is well understood.
By thus combining the ordinary star wheel and faller motions with a screw
of variable pitch I find that, an increased delicacy of action in the regulation
of the winding-on is effected.
Having thus described and ascertained the nature of my said Invention,
and the manner in which the same is to be performed, I desire it to be under-
stood that I claim as secured to me under the above in part recited Letters
Patent the use of a winding-on screw of variable pitch worked by the
ordinary faller, star plate, and endless band arrangement.
In witness whereof, I, the said John Dodd, have hereunto set my hand
and seal, this Twenty-third day of September, in the year of our
Lord One thousand eight hundred and sixty-five.
JOHN DODD. (L.S.)
