IMPROVE- MENTS IN CERTAIN PARTS OF MACHINERY FOR SLUBBING AND ROVING COTTON AND OTHER FIBROUS SUBSTANCES
Year: 1855

page_text: LETTERS PATENT to William Ryder, of Bolton-le-Moors, in the County
of Lancaster, Spindle and Flyer Maker, for the Invention of "IMPROVE-
MENTS IN CERTAIN PARTS OF MACHINERY FOR SLUBBING AND ROVING COTTON
AND OTHER FIBROUS SUBSTANCES."
Sealed the 26th June 1855, and dated the 20th April 1855.
PROVISIONAL SPECIFICATION left by the said William Ryder at the
Office of the Commissioners of Patents, with his Petition, on the
20th April 1855.
I, WILLIAM RYDER, of Bolton-le-Moors, in the County of Lancaster, 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 SUBSTANCES" to be as follows:-
In slubbing and roving frames of the ordinary construction, the presser,
which is hinged or jointed to the flyer leg, is pressed by a spring, or by the
centrifugal action of a weight against the spool or bobbin on which the slub-
bings or rovings are wound. Now, my Invention consists in attaching a tube
or socket to the presser, which, tube or socket fits with sufficient tightness on
the leg of the flyer that the friction between them holds the presser against the
spool or bobbin; by this means, when the slubbings or rovings accumulate on

page_text: the spool or bobbin, the presser is gradually forced out by the slubbings or rovings
under operation. The presser is held on the flyer leg, and the amount of its
motion is regulated by a stud or pin entering a radial slot in the friction tube.
I propose to make the pressers of hollow sheet metal to reduce their weight,
and to make the shank of the presser either plain or in the form of a screw to
guide the slubbing or roving from the flyer leg to the eye of the presser.

SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Ryder in the Great Seal Patent Office on the
20th October 1855.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
RYDER, of Bolton-le-Moors, in the County of Lancaster, Spindle and Flyer
Maker, send greeting.
i. b.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twentieth day of April, in the year of our Lord
One thousand eight hundred and fifty-five, in the eighteenth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said William Ryder, Her. special license that I, the said William Ryder, my
executors, administrators, and assigns, or such others as I, the said William
Ryder, 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 "IMPROVEMENTS IN
PARTS OF MACHINERY FOR SLUBBING AND ROVING COTTON AND OTHER FIBROUS
SUBSTANCES," upon the condition (amongst others) that I, the said William
Ryder, by an instrument in writing under my hand and seal, should parti-
cularly 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 imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said William Ryder, do hereby declare the
nature of my said Invention, and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following Speci-
fication thereof, reference being had to the accompanying Drawing (that
is to say)-

page_text: The nature of my Invention consists in producing by friction the requisite
pressure on the pressers of flyers used in slubbing and roving frames for
winding the rovings on to the bobbins or spools, also in making the pressers of
flyers of hollow sheet metal to reduce their weight.
And in order that my Invention may be fully understood and readily
carried into effect, I will proceed to describe the means pursued by me.
Figure 1 of the said Drawing is an elevation of an ordinary roving frame flyer
to which my improvements are applied; Figure 2 is a side view; and Figure 3,
a plan in section of the same. a, a, are the legs of the flyer, to one of which is
applied my improved presser, consisting of a sheet metal tube band of the
finger c; the tube 6 is open at d, as shewn in the plan, Figure 3, and it is made
to fit so tight on the leg of the flyer, that the friction between the inner surface
of the tube and the exterior of the flyer leg will not only resist the centrifugal
action of the finger c when the flyer is at work, but will also impart the
requisite pressure to the finger for winding the rovings on the spool or bobbin ;
the presser is held on the flyer leg by the stud e, which fits in a radial slot in
the tube b, the length of the slot being sufficient to allow the presser finger c
to be pushed back for piecing and doffing. The presser finger c is made of
hollow sheet metal, which I prefer to stamp in suitable dies in two pieces, and
then solder together along the line f, in Figure 3; the presser finger c when
complete is soldered to the tube b. By so constructing the presser finger the
weight thereof is very materially reduced; consequently the variations in the
balance of the flyer and the centrifugal action of the presser are proportion-
ately diminished. I wish to remark here that I do not limit myself to the
combination of giving pressure to pressers by friction, and constructing such
presser fingers of hollow sheet metal, as the presser fingers of the ordinary
construction may be pressed against the spool by friction; and hollow sheet
metal presser fingers may be used when the requisite pressure is imparted by
springs, or by the centrifugal action of a weight, as in the presser flyers of the
ordinary construction.
Having thus stated the nature of my Invention, and described a mode of
performing the same, I would observe, that whereas in the Provisional Specifi-
cation I stated that I intended to make the shank of the presser in the form
of a screw to guide the slubbing or roving from the flyer leg to the eye of the
presser, I wish it to be understood that since the filing of the said Provisional
Specification I have found that such mode of constructing the said shank of
the presser is not practically beneficial, I therefore make no claim in respect
theroof; but that what I do claim is,-

page_text: First, the application and use of friction for giving pressure to the pressers
of flyers, whether the same be produced as described or otherwise.
And, secondly, constructing the fingers of pressers of hollow sheet metal, as
described.
In witness whereof, I, the said William Ryder, have hereunto set
my hand and seal, this Nineteenth day of October, in the year of our
Lord One thousand eight hundred and fifty-five.
Witness,
H. B. BARLOW,
Manchester.
