AN IMPROVEMENT IN THE CONSTRUCTION " OP BOBBINS EMPLOYED IN SLUBBING, ROVING, AND OTHER SIMILAR MACHINES USED IN THE PREPARATION OF COTTON FOR SPINNING
Year: 1869

page_text: LETTERS PATENT to John Wilson, of Stockport, in the County of
Chester, for the Invention of "AN IMPROVEMENT IN THE CONSTRUCTION
"
OP BOBBINS EMPLOYED IN SLUBBING, ROVING, AND OTHER SIMILAR MACHINES
USED IN THE PREPARATION OF COTTON FOR SPINNING."
Sealed the 14th September 1869, and dated the 1st May 1869.
PROVISIONAL SPECIFICATION left by the said John Wilson at the
Office of the Commissioners of Patents, with his Petition, on the
1st May 1809.
I, JOHN WILSON, of Stockport, in the County of Chester, do hereby
declare the nature of the said Invention for "AN IMPROVEMENT IN THE
CONSTRUCTION OF BOBBINS EMPLOYED IN SLUBBING, ROVING, AND OTHER SIMILAR
MACHINES USED IN THE PREPARATION OF COTTON FOR SPINNING," to be as
follows:-
This Invention relates to the tubular bobbins without ends used in
all such machines where "presser flyers" are employed, and consists
principally in forming such bobbins from a piece of sheet iron cut to a

page_text: suitable width and bent by means of rollers or dies into a cylindrical or
tubular form.
I take a piece of sheet iron of the required-thickness and of a width
equal to the length of the bobbin, and by means of a "guillotine" or
other suitable apparatus I cut it into strips equal in width to the
circumference of the bobbin; I then bend these strips by means of
rollers or dies into a cylindrical form with their edges meeting and
forming a longitudinal joint; I next cut the requisite number of notches
in the end to receive the driving bits and then slightly splay or spread
out the ends.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Wilson in the Great Seal Patent Office
on the 1st November 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
WILSON, of Stockport, in the County of Chester, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the First day of May, in the year of our
Lord One thousand eight hundred and sixty-nine, in the thirty-second
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, the said John Wilson, Her special license that I, the
said John Wilson, my executors, administrators, and assigns, or such
others as I, the said John Wilson, 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 "AN IMPROVEMENT IN THE CONSTRUCTION OF BOBBINS
EMPLOYED IN SLUBBING, ROVING, AND OTHER SIMILAR MACHINES USED IN THE
PREPARATION OF COTTON FOR SPINNING," upon the condition (amongst others)
that I, the said John Wilson, my executors or administrators, by an
instrument in writing under my, or their, or one of their hands 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

page_text: calendar months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said John Wilson, 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 and accompanying Drawings (that is to say):-
This Invention relates to the tubular bobbins without ends used in
all such machines where "
presser flyers" are employed, and consists
principally in forming such bobbins from a piece of sheet iron cut to a
suitable width and bent by means of rollers or dies into a cylindrical or
tubular form.
Such being the nature and object of my said Invention for "An
Improvement in the Construction of Bobbins employed in Slubbing,
Roving, and other similar Machines used in the Preparation of
Cotton for Spinning," I will now proceed to describe more in detail
the manner in which the same is to be or may be performed and
carried into practical effect, and in order that the same may be
clearly understood I have annexed hereunto a Sheet of Drawings
illustrative thereof, and have marked the same with figures and letters
of reference corresponding with those in the following explanation
thereof:-
I take a piece of sheet iron of the required thickness and of a width
equal to the length of the bobbin, and by means of a "guillotine" or
other suitable apparatus I cut it into strips equal in width to the
circumference of the bobbin (see Fig. 1, which shows the size for a
slubbing frame bobbin); I then bend these strips by means of rollers
or dies, or both rollers and dies, into a cylindrical form with their edges
meeting and forming a longitudinal joint, as shown in the side view,
Fig. 2, and end view, Fig. 3. I next cut the requisite number of
notches a, a, a, in the end to receive the driving bits, and then slightly
splay or spread out the ends, as shown in the Drawing, in order to
facilitate the placing of the tubes on the spindles.
Having now described the nature and object of my said Invention,
together with the manner in which the same is to be or may be per-
formed or carried into practical effect, I would remark in conclusion that
it will be evident that if required tubular metal bobbins might be made
in this manner with equal facility from sheet steel, brass, or other metal,

page_text: but I prefer sheet iron as being stronger and more economical in price.
I I may also observe that if preferred the tubes may be made solid by
welding, soldering, or otherwise uniting their edges, but I consider it
unnecessary, and it adds materially to their cost. I wish it therefore to
be distinctly understood that what I claim as my Invention is, the
construction of such bobbins from sheet iron or other suitable metal,
substantially in the manner hercin-before set forth.
In witness whereof, I, the said John Wilson, have hereunto set my
hand and scal, this
day of October, in the year of
our Lord One thousand eight hundred and sixty-nine.

Clerk to George Davies, C.E.,
