Year: 1862

page_text: LETTERS PATENT to William Bodden and William Mercer, both of the
Hargreaves Spindle Works, Oldham, in the County of Lancaster, for the
Invention of "IMPROVEMENTS IN CERTAIN PARTS OF MACHINERY FOR SLUBBING
AND ROVING COTTON AND OTHER FIBROUS SUBSTANCES."
Sealed the 24th October 1862, and dated the 2nd May 1862.
PROVISIONAL SPECIFICATION left by the said William Bodden and
William Mercer at the Office of the Commissioners of Patents, with
their Petition, on the 2nd May 1862.
We, WILLIAM BODDEN and WILLIAM MERCER, both of the Hargreaves
Spindle Works, Oldham, in the County of Lancaster, 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:-
Our Invention is chiefly applicable to the machines for preparing cotton
known as slubbing and roving frames, and it consists in certain improved
modes of connecting the pressers to the legs of the flyers, by which the
slubbings or rovings are wound on the bobbins. The flyer leg to which the
presser is connected is provided with a solid stud or bearing fixed in the lower
end of the flyer leg, and on this stud or bearing the presser is hinged, the
stud having a collar to support the presser which is held in its place between
the collar and the end of the flyer leg; the collar of the stud is of the required
shape to limit the range of the presser, the slit in the presser is thus dispensed
with, and the diameter of the socket of the presser is reduced to the diameter

page_text: of the flyer leg, thereby enabling a bobbin to be made of the diameter of the
inside of the flyer legs. An opening is made in the lower part of the flyer
leg, but above the joint of the presser, for the slubbing or roving to pass through
to the presser.
Our improvements are applicable to centrifugal and spring pressers, and to
double as well as single pressers.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Bodden and William Mercer in the Great Seal
Patent Office on the 31st October 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, WILLIAM
BODDEN and WILLIAM MERCER, both of the Hargreaves Spindle Works,
Oldham, in the County of Lancaster, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Second day of May, in the year of our Lord One
thousand eight hundred and sixty-two, in the twenty-fifth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto us, the said
William Bodden and William Mercer, Her special license that we, the said
William Bodden and William Mercer, our executors, administrators, and
assigns, or such others as we, the said William Bodden and William Mercer,
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 "IMPROVEMENTS IN CERTAIN PARTS OF
MACHINERY FOR SLUBBING AND ROVING COTTON AND OTHER FIBROUS SUBSTANCES,"
upon the condition (amongst others) that we, the said William Bodden and
William Mercer, 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.
NOW KNOW YE, that we, the said William Bodden and William Mercer,
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 (that is to say):-

page_text: Our Invention is chiefly applicable to the machines for preparing cotton
known as slubbing and roving frames, and it consists in certain improved
modes of connecting the pressers to the legs of the flyers by which the
slubbings and rovings are wound on the bobbins. The flyer leg to which the
presser is connected is provided with a solid stud or bearing fixed in the lower
end of the flyer leg, and on this stud or bearing the presser is hinged, the stud
having a collar to support the presser, which is held in its place between the
collar and the end of the flyer leg; the collar of the stud is of the required
shape to limit the range of the presser; the slit in the presser is thus dispensed
with, and the diameter of the socket of the presser is reduced to the diameter
of the flyer leg, thereby enabling a bobbin to be made of the diameter of the
inside of the flyer legs. An opening is made in the lower part of the flyer leg
but above the joint of the presser for the slubbing or roving to pass through to
the presser.
'
Our improvements are applicable to centrifugal and spring pressers, and to
double as well as single-pressers.
And in order that our Invention may be fully understood and readily
carried into operation, we will proceed to describe the accompanying Sheet of
Drawings, reference being had to the figures and letters marked thereon.
Figure 1 is an elevation; Figure 2, an edge view; and Figure 3 a plan.
in section of a presser and flyer suitable for a roving frame, to which one
mode of constructing our improvements is applied; Figure 4 is a section of
part of a flyer leg with the stud for the presser, and Figure 5 is a plan of
the stud.
a is the boss of the flyer; b, the solid leg; and c, the hollow leg; d is the
presser, and e, the weighted arm of the presser, the centrifugal action of which.
holds the presser against the bobbin in the usual manner.
a
Our improved mode of connecting the presser to the flyer leg is performed
in the following manner:-A solid stud or bearing f passes through a hole in
the presser, and into the end of the hollow flyer leg c, where it is secured by
pin, as shewn best in Figure 4, or in any other convenient manner; the stud f
forms the lower bearing for the presser; the head or collar of the stud f holds
the presser up, and the upper end of the weighted arm e of the presser clips
round the flyer leg in the usual manner. The collar of the stud f is provided
with two flat surfaces, as shewn best in Figure 5, and the lower end of the
presser arm is made with a projection e¹; the range of the presser is limited
by this projection coming against either one or the other of the flat surfaces
on the collar of the stud f. The full lines in Figure 3 represent the presser
bearing on the empty bobbin or spool, and the dotted lines indicate the

page_text: position of the presser when it is thrown back for doffing. Above the lower
bearing of the presser a hole g is made in the hollow flyer leg c, for the
slubbing or roving to pass through to the presser, by this means the slubbing
or roving is brought in a more direct line to the presser for being wound on
the bobbin or spool, and less drag is put on the slubbing or roving than by
the usual method in which the slubbing or roving is taken from the end of
the flyer leg and thence to the presser.
This part of our Invention is applicable to centrifugal and spring pressers
of the usual description.
:
Figures 6, 7, 8, 9 and 10, are various views of another flyer and presser
constructed according to our improvements; in this peculiar mode of con-
structing the flyer and presser, the stud f may be made fast to the flyer by
brazing or otherwise, or it may be forged to it; and the presser can be
connected to and disconnected from the flyer in the following manner :-The
head or collar of the stud f projects only at one side, as shewn best in Figure 4,
and at the other side it is bevelled off to allow the hole in the presser to slip
on to the stud; when the lower end of the presser is on the stud the upper
end of the weighted arm c is sprung on to the hollow leg c, thereby securely
connecting the presser above and below to the flyer. The range of the presser
is limited by the two projections e coming against the two sides of the collar
of the stud f. By thus inserting or fixing a stud or bearing to the lower end
of the flyer leg on which the presser swivels and by which it is supported,
all fixings or bearings on the outside of the lower end of the flyer tube are
avoided.
By dispensing with the slit heretofore necessary in the socket of the presser
for springing it on to the end of the flyer leg, the irregularities in the position
of the weighted arm of the presser resulting from the opening, closing, and
straining of the socket are avoided.
Another advantage of our improvements is that the socket of the presser
does not require to exceed in diameter the lower end of the leg of the flyer,
thus allowing a bobbin to be made equal in diameter to the space between the
legs of the flyer.
We wish to remark that our Invention may be modified by making the
stud hollow instead of solid, or by making the stud and presser fast together,
and inserting the stud into the lower end of the flyer leg; also that our
improvements are applicable to double as well as single pressers.
Figures 11 and 12 are two views of a flyer to which the presser is con-
nected in the ordinary manner; the hole g is similar to that before referred to
for the passage of the slubbing or roving to the presser; and as we propose in

page_text: all cases to place the hole g slightly above or in a line with the presser, it is
evident that the slubbing or roving is brought in a more direct manner and
with less drag to the presser.
Having thus stated the nature of our. Invention and described the manner
of performing the same, we declare that we claim,―
First, the improved modes of constructing pressers and flyers shewn and
described.
Secondly, the improved modes of connecting pressers and flyers as shewn
and described.
And, lastly, the opening in the flyer leg marked g for allowing the slubbing
or roving to pass to the presser from a point above or in a line with the
presser.
In witness whereof, we, the said William Bodden and William Mercer,
have hereunto set our hands and seals, this 29 day of October, in
the year of our Lord One thousand eight hundred and sixty-two.
