CERTAIN IMPROVEMENTS IN MACHINERY OR APPARATUS FOR PREPARING AND SPINNING COTTON AND OTHER FIBROUS MATERIALS
Year: 1866

page_text: LETTERS PATENT to William Shorrock Ashton, Spinner and Manufac-'
turer, and James Johnson, Manager, both of Darwen, in the County of
Lancaster, for the Invention of "CERTAIN IMPROVEMENTS IN MACHINERY
OR APPARATUS FOR PREPARING AND SPINNING COTTON AND OTHER FIBROUS
MATERIALS."
Sealed the 9th April 1867, and dated the 1st November 1866.
PROVISIONAL SPECIFICATION left by the said William Shorrock
Ashton and James Johnson at the Office of the Commissioners of
Patents, with their Petition, on the 1st November 1866.
We, WILLIAM SHORROCK ASHTON, Spinner and Manufacturer, and JAMES
JOHNSON, Manager, both of Darwen, in the County of Lancaster, do hereby
declare the nature of the said Invention for "CERTAIN IMPROVEMENTS IN.
MACHINERY OR APPARATUS FOR PREPARING AND SPINNING COTTON AND OTHER
FIBROUS MATERIALS," to be as follows:-
Our Invention relates and is applicable to all descriptions of mechanism
employed for preparing and spinning fibrous materials, wherein top and
bottom rollers, called "drawing and delivery rollers," are used; and the
Invention is designed to collect the "fly" or loose fibrous material, and
prevent the same accumulating on the said rollers.

page_text: The improvements consist in the employment, adaptation, and application
of a bar "clearer" blade or plate in the space between the front rollers and
the back roller; the upper surface of this plate is situated slightly below
the highest surface of the rollers and parallel to the axes thereof; and as the
rollers revolve the "fly" instead of passing back from the front rollers and
accumulating on the back rollers is intercepted by the edge of the plate, and
lodges on the broad surface thereof, and is prevented from passing beyond,
the accumulation thereon being removed when necessary by hand.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Shorrock Ashton and James Johnson in the
Great Seal Patent Office on the 30th April 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, WILLIAM
SHORROCK ASHTON, Spinner and Manufacturer, and JAMES JOHNSON, Manager,
both of Darwen, in the County of Lancaster, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the First day of November, in the year of our Lord
One thousand eight hundred and sixty-six, in the thirtieth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto us, the
said William Shorrock Ashton] and James Johnson, our Her special license
that we, the said William Shorrock Ashton and James Johnson, our
executors, administrators, and assigns, or such others as we, the said William
Shorrock Ashton and James Johnson, 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
"CERTAIN IMPROVEMENTS IN MACHINERY OR APPARATUS FOR PREPARING AND
SPINNING COTTON AND OTHER FIBROUS MATERIALS," upon the condition (amongst
others) that we, the said William Shorrock Ashton and James Johnson,
our executors or administrators, by an instrument in writing under our or
one of our, 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 calendar months next and immediately
after the date of the said Letters Patent.

page_text: NOW KNOW YE, that I, the said William Shorrock Ashton, 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) :-
My Invention relates and is applicable to all descriptions of mechanism
employed for preparing and spinning fibrous materials wherein top and bottom
rollers, called "drawing and delivery rollers," are used; and the Invention is
designed to collect the "fly" or loose fibrous materials, and prevent the
accumulating on the said rollers.
The improvements consist in the employment, adaptation, and application
of a "clearer bar" blade or plate in the space between the front rollers and
the back rollers; the upper surface of the plate is situated slightly below the
highest surface of the rollers, and parallel to the axis thereof; and as the
rollers revolve the "fly" instead of passing back from the front rollers and
accumulating on the back rollers is intercepted by the edge of the plate, and
lodges on the broad surface thereof, and is, prevented from passing beyond,
the accumulation thereon being removed when necessary by hand.
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.
Fig. 1 represents a plan view of the top drawing and delivery rollers of a
first slubbing frame shewing the improved "clearer bar" or plate applied
thereto; and Fig. 2 represents a vertical end section of the drawing rollers
and stand, shewing more particularly the position which the "clearer bars" or
plates occupy between the middle and back top rollers.
'
In Figs. 1 and 2, a, a, is the beam or framework of the slubbing frame
which supports the roller stand and top roller bars c, c.; the clearer bar or
plate is placed in and occupies the space d between the top, middle, and
back rollers d and e, such "clearer bar" being supported and held in position
by means of the top. roller bars c which pass through holes formed in the
mid-feather of the plate f, which when in position is secured to such bars by
means of the set screws g. The upper surface of the plate f is situated
slightly below the highest surface of the rollers d and e, and parallel to the
axis thereof, so that as the rollers revolve the filaments of cotton or "fly"
is intercepted by the edge of the clearer bar or plate f, and is deposited and
accumulates thereupon, whence it is removed when necessary by the attendant
operative.

page_text: 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 we claim the novel application, adaptation, and use of
"clearer bars or plates "situated between the front and back rollers to
remove and to receive the "fly" therefrom in machinery employed in pre-
paring cotton and other fibrous substances, as herein-before described, set
forth, and fully illustrated in the Drawings attached.
In witness whereof; I, the said William Shorrock Ashton, have here-
unto set my hand and seal, this Twenty-ninth day of April, in the year
of our Lord. One thousand eight hundred and sixty-seven.
WILLIAM SHORROCK ASHTON. (L.s.)
