Year: 1861

page_text: LETTERS PATENT to Barnard Collingham, of Keighley, in the County of
York, Worsted Spinner, and Mark Mason, of Manchester, Engineer and
Machinist, for the Invention of "IMPROVEMENTS IN FLYERS EMPLOYED IN
MACHINERY FOR PREPARING AND SPINNING FIBROUS SUBSTANCES."
Scaled the 23rd November 1861, and dated the 24th May 1861.
PROVISIONAL SPECIFICATION left by the said Barnard Collingham.
and Mark Mason at the Office of the Commissioners of Patents, with
their Petition, on the 24th May 1861.
We, BARNARD COLLINGHAM, of Keighley, in the County of York, Worsted:
Spinner, and MARK MASON, of Manchester, Engineer and Machinist, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
FLYERS EMPLOYED IN MACHINERY FOR PREPARING AND SPINNING, FIBROUS SUL-.
STANCES," to be as follows:-
This Invention consists, firstly, in inserting glass, porcelain, or other vitreous.
substance into the eyes of flyers, to prevent them being cut by the rubbing
action of the fibrous substances in passing through the said eyes.
And, secondly, this Invention consists in constructing flyers to open. and

page_text: close in the head or boss. They are binged or jointed and pressed close by a
spring, so as to clip and hold on the spindle; the opening is effected by the
attendant pressing the prongs together, the object of which improvement is to
facilitate the doffing process.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Barnard Collingham and Mark Mason in the Great Scal
Patent Office on the 23rd November 1861.
"
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, BARNARD
COLLINGHAM, of Keighley, in the County of York, Worsted Spinner, and
MARK MASON, of Manchester, Engineer and Machinist, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-fourth day of May, in the year of our Lord
One thousand eight hundred and sixty-one, in the twenty-fourth year of Ier
reign, did, for Herself, Her heirs and successors, give and grant unto us,..the
said Barnard Collingham and Mark Mason, Her special license that we, the
said Barnard Collingham and Mark Mason, our executors, administrators, and
assigns, or such others as we, the said Barnard Collingham and Mark Mason, our
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 FLYERS EMPLOYED IN MACHINERY
FOR PREPARING AND SPINNING FIBROUS SUBSTANCES," upon the condition,
amongst others, that we, the said Barnard Collingham and Mark Mason,
our executors or administrators, by an instrument in writing under our, or
their, or one of our or their hands and seals, should particularly describo
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 we, the said Barnard Collingham and Mark Mason,
do hereby declare the nature of the said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained in and
by the following statement (that is to say):
This Invention consists, firstly, in inserting glass, porcelain, or other vitreous

page_text: substance into the eyes of flyers, to prevent them being cut by the rubbing
action of fibrous substances passing through.
And, secondly, in constructing flyers with joints, to open and close in the
licad or boss so as to facilitate the doffing.
In carrying the first part of this Invention into practice, we employ the
ordinary flyers as at present in use, or wo have them of similar construction or
form, but instead of being made of steel as at present we make them of either
wrought iron or maleable cast iron, on account of cheapness, and being less
liable to break by a fall. We then cut a groove across the face of the eye or
tweezle to about one-half the thickness of the substance of the metal, and on
that side of the eye or aperture on which the yarn or thread rubs, and at about
right angles to the line of its passage from the eye to the bobbin; we then
insert a slip of glass or other vitreous substance, which we embed in shellac or
other suitable cement, or we secure it therein by solder, or we form such
groove into a dovetail, and press or force the slips of glass or other vitreous
substance therein, which will be held by close contact with the metal, or we
bore through the substance of the metal forming the eye or tweezle at the
proper angle, and press or force a slip of glass or other vitreous substance
therein, which, as before stated, may be either secured by cement or by close
fitting. The advantages of flyers thus made or provided with glass on the
rubbing side of the eye or tweezle are, that they are not liable to break by a
fall, and do not wear by the rubbing action of the yarn in passing through,
consequently the cost of frequent repairs is avoided, and if such slips of glass
be broken or become worn, the flyers may readily be repaired by inserting
other slips.
The second part of our Invention is effected by placing a bridge-piece across
the flyer, which is hinged or jointed to the prongs or arms thereof, and by
cutting through the boss or head of the flyer it becomes capable of opening.
A C-spring is attached to the bridge, which clips on the boss to press and hold
it together, and when required to be opened the attendant presses on the
prongs below the bridge. By means of this improvement the flyers can readily
be removed from the spindles, and as readily replaced, whereby the the process
of doffing can be done with greater facility than heretofore.
Having thus described the nature of this our said Invention, and the manner
in which the same is performed, we would have it understood that we do not
confine ourselves to any particular mode of inserting and securing the slips of
glass; but what we claim as of our Invention, and which we believe to be
new is,―

page_text: Firstly, the inserting slips of glass, porcelain, or other vitreous substance
into the eyes or tweezle of flyers.
Secondly, the constructing flyers to open in the boss or head.
In witness whereof, I, the said Barnard Collingham, for and on behalf
of myself and the said Mark Mason, have hereunto set my hand and 5
seal, this Twenty-first day of November, One thousand eight hundred
and sixty-one.
BARNARD COLLINGHAM. (L.S.)
Signed, sealed, and delivered by the
within-named Barnard Collingham,
in the presence of
W. TASKER, Patent Agent,
Halifax.
