CERTAIN IMPROVEMENTS IN COP TUBES
Year: 1860

page_text: LETTERS PATENT to Samuel Cheetham, of Manchester, in the County
of Lancaster, Engineer, for the Invention of "CERTAIN IMPROVEMENTS IN
COP TUBES."
Sealed the 11th October 1860, and dated the 17th April 1860.
PROVISIONAL SPECIFICATION left by the said Samuel Cheetham at
the Office of the Commissioners of Patents, with his Petition, on the
17th April 1860.
I, SAMUEL CHEETHAM, of Manchester, in the County of Lancaster, Engincer,
do hereby declare the nature of the said Invention for "CERTAIN IMPROVE-
MENTS IN COP TUBES," to be as follows:-
My Invention relates to certain articles employed in the operation of spin-
ning cotton and other fibrous substances, now well known as "cop tubes,"
being tubes placed upon the spindles, upon which "cops" are built or wound
instead of upon the spindles themselves, and used for the prevention of waste.
The Invention is principally applicable to "cop tubes" formed of metal, but
is also applicable when made of paper, papier machie, or stiffened woven fabric,
and consists, first, in forming an opening or slot in the tube in the direction of
its length, so that when placed upon the "skewer" in the shuttle for weaving,
the skewer spring" may project through such slot and press upon the
interior of the cop to retain it in its proper position, or if pressed such slot
may extend from end to end of the tube for the same object.

page_text: Secondly, the improvement consists in increasing the diameter of the larger
end of the tube, which renders the tube "trumpet-mouthed," or better adapted
to the interior form of the cop than tubes regularly tapered from end to end.
And, thirdly, in providing a fastening or method of attaching the tube to
the shuttle skewer, which may be effected by means of a pin upon the skewer,
which will enter a hole in a projection upon the larger end of the tube, or the
pin may be upon the projection of the tube and the hole in the skewer.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Samuel Cheetham, in the Great Seal Patent Office on the
17th October 1860.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, SAMUEL
CHEETHAM, of Manchester, in the County of Lancaster, Engineer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Seventeenth day of April, in the year of our Lord
One thousand eight hundred and sixty, in the twenty-third year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Samuel Cheetham, Her special license that 1, the said Samuel Cheetham,
my executors, administrators, and assigns, or such others as I, the said
Samuel Cheetham, 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 "CERTAIN IMPROVE-
MENTS IN COP TUBES," upon the condition, amongst others, that I, the said
Samuel Cheetham, by an instrument in writing under my hand and scal,
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 Samuel Cheetham, 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) :-
My Invention relates to certain articles employed in the operation of
spinning cotton and other fibrous substances, now well known as "cop tubes,"

page_text: being tubes placed upon the spindles upon which "cops" are built or wound,
instead of upon the spindles themselves, and used for the prevention of waste.
The Invention is principally applicable to cop tubes formed of metal; but is
also applicable when made of paper, papier mache, or stiffened woven fabric,
and consists, first, in forming an opening or slot in the tube in the direction
of its length, so that when placed upon the "skewer" in the shuttle for
weaving, the "skewer spring" may project through such slot and press upon
the interior of the cop to retain it in its proper position; or, if preferred, such
slot may extend from end to end of the tube for the same object.
Secondly, the improvement consists in increasing the diameter of the larger
end of the tube, which renders the tubo "trumpet-mouthed," or better
adapted to the interior form of the cop than tubes regularly tapered from en
to end.
And, thirdly, in providing a fastening or method of attaching the tube to
the shuttle skewer, which may be effected by means of a pin upon the
"skewer," which will enter into a hole in a projection upon the larger end of
the tube, or the pin may be upon the projection of the tube, and the hole in
the skewer.
In order that the Invention may be better understood and explained in
detail, I have hereunto attached a Sheet of Drawings, made about the real
size.
Fig. 1 represents a cop tube," having an opening or slot formed therein
from end to end for the spring on the "skewer" to pass through; Fig. 2
shows a tube, having a slot for a like purpose, but not continued to the ends,
the edges of the metal forming the tube overlapping at each end; a shorter
tube of the same construction being represented by Fig. 3; Fig. 4 shews a
tube having the edges of the metal overlapping at one end only, the slot being
continued to the other end; Fig. 5 shews a tube closed from end to end, the
edges of the metal overlapping to prevent the thread or yarn catching the
overlapping edge, being formed of a curve or series of curves for the same
purpose; and Fig. 6 represents a tube, formed with an enlarged or "trumpet-
mouthed "end.
In Figs. 1 to 4, a is the "cop tube," upon which the "cop" is "built" or
wound; 6 is the slot or opening for the spring, to project through when the
cop is placed upon the "shuttle skewer;" and c is the projecting piece, in which
the hole or pin is placed to retain the tube upon the skewer. The end d of
the tube is sometimes closed by soldering, fitting on a cap, or any other method,
for the purpose of preventing the thread catching.
In the above description, reference is made more particularly to "cop

page_text: tubes" formed of sheet metal bent round into the tubular form; but the Inven-
tion is applicable to tubes made by other methods and of other materials, as
the slot 6 may be cut or " punched" after the tube is formed.
Having now described the nature of the said Invention, together with the
manner of carrying the same into practical effect, I wish it to be distinctly
understood that I claim,-
Firstly, forming slots in "cop tubes" for the purpose of allowing the
"skewer spring" to press upon the cop, and of balancing the tube whilst in
the process of formation.
And, secondly, I claim securing "cop tubes" upon the "skewer" by means
of a pin entering a hole conveniently disposed for the purpose.
In witness whercof, I, the said Samuel Cheetham, have hereunto set
my hand and scal, this Sixteenth day of October, in the year of our
Lord One thousand eight hundred and sixty.
