IM- PROVEMENTS IN CERTAIN PARTS OF MACHINERY FOR SLUBBING AND ROVING PROVISIONAL SPECIFICATION
Year: 1856

page_text: LETTERS PATENT to William Seed, of Preston, in the County of Lancaster,
Spindle and Flyer Maker, and William Ryder, of Bolton-le-Moors, in
the same County, Spindle and Flyer Maker, for the Invention of "IM-
PROVEMENTS IN CERTAIN PARTS OF MACHINERY FOR SLUBBING AND ROVING
PROVISIONAL SPECIFICATION left by the said William Seed and
William Ryder at the Office of the Commissioners of Patents, with their
Petition, on the 5th November 1856.
We, WILLIAM SEED, of Preston, in the County of Lancaster, Spindle and
Flyer Maker, and WILLIAM RYDER, of Bolton-le-Moors, in the said County,
Spindle and Flyer Maker, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN CERTAIN PARTS OF MACHINERY FOR SLUBBING AND ROVING
COTTON AND OTHER FIBROUS MATERIALS," to be as follows:-
Our Invention relates, first, to certain improvements in centrifugal presses
for the flyers of slubbing and roving frames, and consists in supporting the
presser in bearings projecting more than usual from the flyer leg, by which
means the finger and the counterbalance of the presser are brought to the same
side of the flyer leg. The leg or counterbalance of the presser is so shaped that

page_text: the centrifugal action produced by the revolving flyer maintains a uniform or
nearly uniform pressure of the presser during the accumulation of the slubbings
or rovings on the spool or bobbin. The weight and cost of the presser are
reduced, and the equibrium of the flyer is maintained during the filling of the
bobbin or spool.
Another part of our Invention consists in forming the bearings to support
pressers of iron, steel, brass, or other sheet metal bent to the required shape,
and soldered or otherwise fixed to the flyer leg, whereby the weight and cost
of the bearings are reduced.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Seed and William Ryder in the Great Seal Patent
Office on the 4th May 1857.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, WILLIAM
SEED, of Preston, in the County of Lancaster, Spindle and Flyer Maker, and
WILLIAM RYDER, of Bolton-le-Moors, in the same County, Spindle and Flyer
Maker, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fifth day of November, in the year of our Lord
One thousand eight hundred and fifty-six, in the twentieth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto us, the said
William Seed and William Ryder, Her special licenso that we, the said
William Seed and William Ryder, our executors, administrators, and assigns,
or such others as we, the said William Seed and William Ryder, 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 mako, use, exercise, and vend, within
the United Kingdom of Great Britain and Ireland, the Channel Islands, and
Isle of Man, an Invention for "IMPROVEMENTS IN CERTAIN PARTS OF MACHINERY
FOR SLUBBING AND ROVING COTTON AND OTHER FIBROUS MATERIALS," upon the
condition (amongst others) that we, the said William Seed and William
Ryder, our executors or administrators, by an instrument in writing under
our or their, or one of our or 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 we, the said William Seed and William Ryder, do
hereby declare the nature of our said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained in
and by the following statement, reference being had to the accompanying
Drawings, and to the letters and figures marked thereon (that is to say) :-
Our said Invention relates, first, to certain improvements in the pressers for
the flyers of slubbing and roving frames, known as "Seed's patent centrifugal
pressers," and consists in so shaping the counterbalance of the presser that
the centrifugal action produced by the flyer when revolving maintains a
uniform or nearly uniform pressure of the presser during the accumulation of
the slubbings or rovings on the spool or bobbin.
Secondly, our Invention consists in forming the bearings to support pressers
of iron, steel, brass, or other sheet metal bent to the required shape, and
soldered or otherwise fixed to the flyer leg.
And in order that the said Invention may be properly understood, we will
now proceed to describe the several Figures on the Sheet of Drawings.
appended hereto for the purpose of shewing certain forms under which our
improvements may be advantageously carried out in practice.
Figure 1 on the Sheet of Drawings is an elevation, Figure 2 an edge view,
and Figure 3, a plan of a roving frame flyer of the ordinary construction, to
which one of our improved pressers is applied. a is the hollow leg of the
presser, to which are soldered or otherwise attached the bearings 6 and c.
These bearings project more than usual from the flyer leg, and may be made
in the ordinary manner, or of sheet metal bent to the proper shape, and
soldered or otherwise fixed to the flyer leg. The finger or presser d is of the
usual shape, but the counterbalance of the presser marked e is so shaped as to
form a crank between the bearings b. and c. The full lines in Figures 3 and 4
represent the finger or presser d in contact with the bare spool or bobbin f,
and the dotted lines shew the position of the parts when the presser is laying
the roving on the full bobbin indicated by the dotted circle f. Figure 5 is
an elevation, Figure 6 an edge view, and Figure 7 a plan of a modification of
our improved pressers; the principal difference between this presser and the
one above described is that the bearings b and c are not longer than those
usually employed, and that the finger or presser is not at the same side of the
flyer leg as the bearings; by this arrangement the counterbalance of the
presser is taken in the direction from the flyer leg instead of towards it, as
before described, and the roving after passing down the leg a is brought more
directly to the finger of the presser, thereby reducing the drag on the roving at
that particular point. The action of this presser is similar to that above

page_text: described. The advantages resulting from our improvements are a reduction
in the weight and cost of the prossers, and the capability of working the
spindles and flyers at great velocities with less vibration, owing to the lightness
and equilibrium of the pressers.
Having now described and particularly, ascertained the nature of our said
Invention, and the manner in which the same is or may bo carried into effect,
we would observe, in conclusion, that we do not confino or restrict ourselves to.
the precise details or arrangements shewn and described, as the same may be
varied without departing from the peculiar character of our Invention; but
what we consider novel or original, and therefore claim as the Invention
secured to us by the herein-before in part recited Letters Patent, is,-
First, the improved centrifugal pressers, as shewn and described, in which
the counterbalance is supported between two bearings fixed to the flyer leg,
and cranked or shaped to produce the required pressure on the presser..
Secondly, bringing the finger of the presser under the open leg of the flyer,
as shewn and described in reference to Figures 5, 6, and 7.
And, lastly, forming the bearings to support the pressers of flyers of sheet
metal, as shewn and described.
In witness whereof, we, the said William Seed and William Ryder,
have hereuunto set our bands and seals, this Second day of May,
in the year of our Lord One thousand eight hundred and fifty-seven.
