WHEREAS Her present most Excellent Majesty Queen Victoria, by -Her
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, the Twenty-second day of April, in the eighth year of Her reign, and
of our Lord One thousand eight hundred and forty-five, did, for
Herself, Her heirs and successors; give and grant unto me; the said James
Ivers, Her especial license, full power, sole privilege and authority, that I,' the
said James Ivers, my executors, administrators, and assigns, and such others
as I, the said James Ivers, my executors, "administrators, and 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 POR PREPARING, ROVING, AND SLUBBING COTTON, WOOL, AND OTHER
FIBROUS SUBSTANCES," in which said Letters Patent is contained a proviso that
I the said James Ivers, shall cause a particular description of the nature of
my said Invention, and in what manner the same is to be performed, to be
inrolled 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
James Ivers, 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 liereto annexed, and the following expla-
nation thereof (that is to say):-
My Improvements in Machinery or Apparatus for Preparing, Roving, and
Slubbing Cotton,, Wool, and other Fibrous Substances, are applicable to the
ordinary machinery employed for the above-named purposes, and particularly
to that part of the same called the "flyer."
My improvements consist,―
Firstly, in the novel and peculiar manner of applying the pressure to those
commonly called the "presser flyers," by the adaptation of a double elastic
spring, which has its fulcrum on a central stud attached to the tubular arm of
such flyer; and,
Secondly, in the novel application of either steel or case-hardened iron
presser levers or spurs to the flyers, which will be found to be a considerable
improvement, both in lightness and durability, in comparison with the
ordinary brass "pressers" now in use.
of steel or case-
. And the third part of my improvements consists in being enabled (if it be
preferred) to form a hard or pressed bobbin of rovings, perfectly cylindrical,
from one head or shroud of the bobbin to the other, instead of forming the
bobbin of rovings with conical ends as usual. As this can only be done by
the use of the improved mode of forming the presser
hardened iron, and thereby making it so light as to be capable of winding
on a hard or pressed bobbin completely up to the shrouds or ends, my
Invention will be readily understood by reference to the accompanying
Drawing, in which Figure 1 is a front elevation, and Figure 2 a side elevation
of my improved "flyer" complete, with spindle and bobbin attached, and of
the real size, as employed in roving frames in the preparation of cotton for
spinning. a is the spindle; b, b, the flyer, one arm being solid and the other
tubular, for the passage of the roving; and c is the "presser lever" (formed
as usual for conducting the roving and winding it on to the bobbin & com-
pactly), but in this instance being made of steel or iron case-hardened, instead
of brass, as in common use. Now it will be seen that the principal feature
of novelty consists in the employment, application, or use of the double elastic
spring e, e, by which the "presser" is kept against the bobbin of rovings as it
is formed, the upper end of this spring having a fixed bearing at f, and the
lower end of the same acting against the tail of the "presser" at 9, as usual,
and having as it were a double elastic action by means of its central fulcrum
swivelling on the stud h, which is fast to the arm of the flyer.

page_text: Having now fully described the nature and object of my said Invention, and
exhibited the same most distinctly in the Drawings attached to these Presents,
I desire it to be understood that I claim as my Invention, and which is secured
to me by virtue of the above-recited Letters Patent, the novel and particular
construction of "presser flyers," to be, employed in the preparation of cotton for
spinning, as herein described and set forth; and particularly the application and
use of the double elastic spring e, e, and also the application and use of steel
or case-hardened iron "pressers," instead of brass or composition metal, as
usually employed; and also the making or forming of cylindrical pressed bobbins
of rovings without taper ends, by the use of the above-described "presser
flyer."
In witness whereof I, the said James Ivers, have hereunto set my hand
and seal, this Twenty-first day of October, in the year of our Lord
Inrolled the Twenty-second day of October in the year above written.
