Year: 1856

page_text: LETTERS PATENT to William Macpherson, of the City of Manchester,.
Manager, for the Invention of "CERTAIN IMPROVEMENTS IN MACHINERY
FOR SPINNING AND DOUBLING COTTON AND OTHER FIBROUS MATERIALS."
Sealed the 5th June 1857, and dated the 24th December 1856.
PROVISIONAL SPECIFICATION left by the said William Macpherson
at the Office of the Commissioners of Patents, with his Petition, on
the 24th December 1856.
I,. WILLIAM MACPHERSON, of the City of Manchester, Manager, do hereby
declare the nature of the said Invention for "CERTAIN IMPROVEMENTS IN
MACHINERY FOR SPINNING AND DOUBLING COTTON AND OTHER FIBROUS MATERIALS,"
be as follows:-
The nature of my Invention consists, first, in the application of a ring or washer
to the inside of the boss of flyers used in machinery for spinning and doubling,
by which the friction, of the bobbin head on the yarn may be entirely
avoided.
Another part of my Invention consists in the application of a ring or rings
to the legs of flyers used in machinery for spinning and doubling, to prevent
the expanding of the legs of such flyers by the action of centrifugal force.

by the said William Macpherson in the Great Seal Patent Office on
the 24th June 1857.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
MACPHERSON, of the City of Manchester, Manager, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-fourth day of December, in the year of our
Lord One thousand eight hundred and fifty-six, in the twentieth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said William Macpherson, Her special licence that I, the said William Mac-
pherson, my executors, administrators, and assigns, or such others as I, the said
William Macpherson, 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, exer-
cise, and vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "CERTAIN IMPROVEMENTS
IN MACHINERY FOR SPINNING AND DOUBLING COTTON AND OTHER FIBROUS MATERIALS,"
upon the condition (amongst others) that I, the said William Macpherson,
my executors or administrators, by an instrument in writing under my, or
their, or one of their bands 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 William Macpherson, 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 (that is to say):-
My Invention relates to that part of the machinery for spinning and
doubling called the flyer, and consists in the application of a ring or washer to
the inside of the boss of the flyer, to guide the yarn beyond the bobbin head,
and thereby to avoid friction; also in the application of a ring or rings to the
legs of the flyers, to prevent the expanding thereof by the centrifugal action
of the same when revolving, and to guide the yarn beyond the head of the
bobbin.

"...
And in order that my Invention may be fully understood and readily carried
into ellect, I will proceed to describe the accompanying Sheet of Drawings,
reference being had to the figures and letters inarked thereon.
Fig. 1 is an elevation of the spindle of a throstle spinning frame, and of a

page_text: flyer to which part of my improvements are applied; Fig. 2 is another
clevation; and Fig. 3, a plan of my improved flyer. a, a, are the legs of the
flyer, which are connected together at the boss b, to the under side of which is
soldered or otherwise attached the ring or washer c. The flyer is screwed to
the spindle d, which is provided with a bobbin e, for the yarn to be wound on
in the usual manner. The yarn is conveyed from the guide wire above the
point of the spindle, over the ring or washer c, to one of the flyer legs, as shewn
by a dotted line in Fig. 1, around which it is wound once or more times, and
after passing through the eye of the flyer leg it is wound on the bobbin e; the
ring or washer c thus serves as a guide to prevent the yarn coming in contact
with the head of the bobbin, thereby avoiding the friction of the yarn on the
bobbin head.
Fig. 4 represents a flyer to which a modification of my Invention is applied;
and Fig. 5 is a plan of the same. In this instance the ring or washer c, under
the boss, is dispensed with, and a ring f is soldered or otherwise attached to the
flyer legs; this ring f serves to guide the yarn over the bobbin head, and
prevents the expanding of the legs by the action of centrifugal force. By
means of my improvements, a more even yarn is produced by avoiding the
friction on the bobbin head, and the flyers may be made to revolve at greater
velocities than heretofore, owing to the ring f preventing the expansion of the
flyer legs.
Having thus described the nature of my Invention, and the manner of per-
forming the same, I wish it to be understood that I do not limit myself to the
details set forth, as the ring or washer c and the ring f, instead of being used
separately, may be combined, and the position of the ring f may be varied; in
some cases two or more rings, similar to f, may be applied to the same flyer.
But what I do claim is,-
First, the ring or washer c applied to the inside of the boss of the flyer, in
the manner and for the purposes described; and,
Secondly, the ring or rings f, for guiding the yarn and for preventing the
expansion of the flyer legs.
In witness whereof I, the said William Macpherson, have hereunto set
my hand and seal, this Twenty-third day of June, in the year of our
Lord One thousand eight hundred and fifty-seven.
WILLIAM MACPHERSON. (L.B.)
