CERTAIN IMPROVEMENTS IN APPARATUS TO BE EMPLOYED IN SPINNING COTTON AND OTHER FIBROUS MATERIALS
Year: 1865

page_text: Sealed the 7th November 1865, and dated the 19th May 1865.
PROVISIONAL SPECIFICATION left by the said Thomas Marsden at the
Office of the Commissioners of Patents, with his Petition, on the 19th
May 1865.
I, THOMAS MARSDEN, of Pemberton, near Wigan, in the County of Lancaster,
Cotton Spinner, do hereby declare the nature of the said Invention for " CERTAIN
IMPROVEMENTS IN APPARATUS TO BE EMPLOYED IN SPINNING COTTON AND OTHER
FIBROUS MATERIALS," to be as follows:-
My Invention relates to a means of retarding the flanged bobbins employed
in spinning cotton and other fibrous substances, and is designed to affect a
light but regular "drag" on the said description of bobbins during their
revolution, which is generally called the "drag motion" and has hitherto
been effected by thick flannel or felt washers placed on the "bobbin rail,"
which method has created too much friction and been irregular in its action.

page_text: The improvements consist in attaching beneath the lower flange of the bobbin
or "spool" two or more pieces of thin flannel, felt, or equivalent material,
which shall revolve on the rail but with the bobbin being connected therewith;
the attachment may be made by tapering two ends of the felt and passing
them into holes drilled in the flange, securing the ends by glue or other
adhesive substance, or by other means, so that the surface of the felt is not
attached directly to the flange which would render it too solid. These pieces
of felt should be placed at each side of the vertical centre of the bobbin so
as to balance each other, or they may be placed triangularly or quadrangularly.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Thomas Marsden, in the Great Seal Patent Office on the
18th November 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
MARSDEN, of Pemberton, near Wigan, in the County of Lancaster, Cotton
Spinner, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Nineteenth day of May, 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 Thomas Marsden, Her special license that I, the said Thomas Marsden,
my executors, administrators, and assigns, or such others as I, the said
Thomas Marsden, 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 APPARATUS TO BE EMPLOYED IN SPINNING COTTON AND OTHER FIBROUS
MATERIALS," upon the condition (amongst others) that I, the said Thomas
Marsden, my executors or administrators, 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 Thomas Marsden, do hereby declare
the nature of the said Invention, and in what manner the same is to be

page_text: performed, to be particularly described and ascertained in and by the follow-
ing statement, and accompanying Drawings, that is to say :-
My Invention relates to a means of retarding the flanged bobbins employed
in spinning cotton and other fibrous substances, and is designed to effect a
light but regular "drag" on the said description of bobbins during their
revolution, which is generally called the " drag motion," and has hitherto
been effected by thick flannel or felt washers placed on the "bobbin rail,"
which method has created too much friction and been irregular in its action.
The improvements consist in attaching beneath the lower, flange of the bobbin
or "spool" one or more pieces of thin flannel, felt, or equivalent material
which shall revolve on the rail, but with the bobbin being connected therewith;
the attachment may be made by tapering two ends of the felt, and passing
them into holes drilled in the flange, securing the ends by glue or other
adhesive substance, or by other means, so that the surface of the felt is not
attached directly to the flange which would render it too solid. These pieces
of felt should be placed at each side of the vertical centre of the bobbin so
as to balance each other, or they may be placed triangularly or quadrangularly.
In order that the Invention may be better understood and explained in detail,
I have hereunto attached a Sheet of Drawings made about the full size.
Figure 1 represents an ordinary bobbin or spool employed upon the machines
known as "throstles," to the under surface of the bottom flange thereof my
improved "drag felt" is applied; Figure 2 represents the under surface of
the lower flange of the bobbin shewing the position and arrangement of the
several pieces of thin flannel, felt, or equivalent material, whereby the friction
upon the rail, and consequent drag upon the bobbin is effected; and Figure 3
represents a detached view of one of the pieces of felt shewing its form.
In Figures 1 and 2 a, a, is the bobbin or spool, to the lower flange of which
are secured the separate pieces of felt or other equivalent material b, b, b,
these pieces of flannel or felt are separately secured to the under side of the
lower flange of the bobbin by having their taper ends c, c, (seen in Figure 3)
glued and inserted into holes bored therein, so that the surfaces of the felt,
marked X, are not directly attached to the flange, which would render it too
solid.
Having now described the nature of the said Invention, together with
the method of carrying the same into practical effect, I wish it to be distinctly
understood that I claim the novel application and use of felt, flannel, or
equivalent material; permanently secured to the lower surface of the bobbins
so as to revolve with them, instead of placing the felt on the rail and detached

page_text: from the bobbin as hitherto employed, as herein-before described, set forth, and
fully illustrated in the Drawings.
In witness whereof, I, the said Thomas Marsden, have hereunto set my
hand and seal, this Seventeenth day of November, in the year of our Lord
One thousand eight hundred and sixty-five.
THOMAS MARSDEN. (L.s.)
