CERTAIN IMPROVEMENTS IN MACHINERY OR APPARATUS FOR PREPARING, SLUBBING, AND ROVING, COTTON AND OTHER FIBROUS MATERIALS
Year: 1846

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
WARBURTON, of Kearsley, in the County of Lancaster, Tinsmith, send
greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Eighth day of October, in the tenth year of Her reign,
and in the year of our Lord One thousand eight hundred and forty-six, did, for
Herself, Her heirs and successors, give and grant unto me, the said John
Warburton, Her especial licence, full power, sole privilege and authority,
that I, the said John Warburton, my executors, administrators, and assigns,
and such others as I, the said John Warburton, my executors, administrators,
or assigns, should at any time agree with, and no others, from time to time and
at all times during the term of years therein expressed, should and lawfully
might make, use, exercise, and vend, within England and Wales and the
Town of Berwick-upon-Tweed, my Invention of "CERTAIN IMPROVEMENTS IN
MACHINERY OR APPARATUS FOR PREPARING, SLUBBING, AND ROVING, COTTON AND
OTHER FIBROUS MATERIALS;" in which said Letters Patent is contained a proviso
that I, the said John Warburton, shall cause a particular description of the
nature of my said Invention, and in what manner the same is to be per-
formed, to be enrolled in Her Majesty's High Court of Chancery within
six calendar months next and immediately after the date of the said in part
recited Letters Patent, as in and by the same, reference being thereunto had,
will more fully and at large appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
John Warburton, do hereby declare that the nature of my said Invention, and
the manner in which the same is to be performed, is particularly described
and ascertained in and by the Drawings hereto annexed, and the following
explanation thereof (that is to say) :-
My Improvements in Machinery or Apparatus for Preparing, Slubbing.
and Roving, Cotton and other Fibrous Materials apply solely to machines
employed in such processes, and commonly called " presser frames," and more
particularly to the part or parts of such machines called the "flyer." As
many Inventions have lately been practised, wherein a great variety of novel
modes of giving elasticity to that part of the flyer called the "presser" have
been the subject of improvement, I would, for the sake of distinction, state
that my improvements apply to the old " presser flyer," or that in which the
long tail spring is used, attached at the upper end to the flyer leg, and consist,
first, in a simple method of regulating the action of such spring, and also of
applying the spring to the presser lever in such a manner that, when the bobbin
is filled, and it is required to "doff" or remove it from the spindle, the
"presser" can be readily shifted backwards, and caused to stand out of the
way whilst the attendant is doffing the bobbin, without any risk of damage
to the full bobbin whilst being removed, or the necessity of the presser being
held back or kept off the bobbin by the hand of the attendant, as usual.
In order that these improvements may be better explained and fully under-
stood, I have attached to these Presents several views of the apparatus, and
the application of the same to old "presser flyers" (or those originally in
use), for the purpose of shewing their practical utility, and have marked the
same with figures and letters of reference corresponding with the following
explanation thereof, the Drawings being made full size, and having the novel
parts, as applied, shaded with color, the old mechanism being shewn in outline,
merely to illustrate their relative positions.
In the Drawing accompanying these Presents, Figure 1 represents a front
view of a spindle and flyer with my improvements applied thereto; Figure 2,
a side view of the same; Figure 3, a sectional plan or horizontal view,
taken at the line A, B, in Figure 1; and Figure 4, a similar view, taken at
the line C, D, in the same Figure. a, a, is the spindle; b, b, the flyer; c, c, the
bobbin of rovings, &c.; and d, d, the tail spring of the ordinary "presser
frame."
My improvements consist.―
Firstly, in the application to one or both legs of the flyer, as the case may
be, of the guide-piece e, with its inclined slot or opening, as seen best in Figure 3,

page_text: Secondly, in the employment or use of a small link g, or intermediate con-
necting piece, for attaching the spring d to the presser f, which, being allowed
to swivel loosely at both ends, enables the presser f to be pushed back, and
secured out of the way of the full bobbin whilst doffing, as shewn in dotted
lines, Figure 4. Detached views of the presser f and its attaching link g are
shewn at Figure 5.
Having now described the nature of my said Invention, and the manner of
carrying the same into practical effect, I desire it to be understood that I
claim,
Firstly, with reference only to those machines used in the preparing,
slubbing, and roving of cotton and other fibrous materials, wherein the
ordinary "presser flyers" are used, the application or employment of the
grooved guide-piece e, or other similar contrivance, for the purpose of regu-
lating the action of the tail spring d upon the presser; and,
Secondly, the adaptation and use of the connecting link g, or other similar
contrivance, whereby the tail spring is enabled to retain the presser f in the
required position whilst doffing, and also to impart the necessary elasticity to
the presser.
In witness whereof, I, the said John Warburton, have hereunto set my
hand and seal, this Sixth day of April, One thousand eight hundred
and forty-seven
