Improvements in the Manufacture of Presser. Flyers.
We, JOHN WARBURTON and HENRY STUTTARD, both of Priory Mill, Union
Street, Oldham, in the County of Lancaster, Spindle and Flyer Makers, do hereby
declare the nature of this invention to be as follows:-
This invention relates to the manufacture of presser flyers" such as are used in
connection with the spindles of slubbing intermediate and roving frames employed
in machinery for preparing cotton and other fibrous substances for spinning.
The invention consists in forging or otherwise forming a solid end to the hollow
leg of the flyer the hollow part being provided just above this solid end with a
notch or opening into the tube and the solid end being slightly excentric to the
hollow leg the cotton (or other fibrous substance) can pass through this opening to
the presser arm.
A neck is turned in the solid end of the hollow leg of the flyer to form a pivot
for the presser arm, and a lock or check is provided to limit the movement of the
latter.

COMPLETE SPECIFICATION.
Improvements in the Manufacture of Presser Flyers.
We, JOHN WARBURTON and HENRY STUTTARD, both of Priory Mill, Union
Street, Oldham, in the County of Lancaster, Spindle and Flyer Makers, do hereby
declare the nature of this invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement :-
This invention relates to the manufacture of " presser flyers" such as are used
in connection with the spindles of slubbing, intermediate, and roving frames
employed in machinery for preparing cotton and other fibrous substances for
spinning.
The nature of our said invention and the manner in which the same is to be
performed or carried into practical effect will be readily understood on reference to
the accompanying sheet of drawings and the following explanation thereof.
Fig. on the drawings is a face view and Fig. 2 an edge view of a presser flyer
made according to our invention and Fig. 3 is an underneath view of the presser
arm and lower end of the hollow leg.
Figs. 4 and 5 are face and edge views of a presser flyer showing how we should
adapt our invention to the alteration of flyers now in use and Fig. 6 is a section
taken through about the line A-B looking upwards.
The invention consists principally in forging or otherwise forming a solid end a*
to the lower end of the hollow leg a of the flyer, the hollow part being provided
just above the solid end with a notch or opening & into the tube, and the solid end a*
being preferably slightly excentric to the hollow leg, the cotton, or other fibrous
substance, can pass out through this opening to the presser arm c. The slit d
through which the sliver or roving is threaded of course terminates at the
opening.
A neck is turned in the solid end a* of the hollow leg a of the flyer to form a
pivot for the presser arm c to turn on.

page_text: The tail ex of the presser is carried upward and its upper end bent round the
upper part of the hollow leg.
In altering existing flyers this upper end may be bent in between the two lumps e
and formed with projections (see Fig. 1) which act against the top lump and thus
form a lock or check to limit the movement of the arm, but in making new flyers
we prefer to form a notch on one side of the solid end (see Fig. 3) and a stop or
projection on the presser c which answers the same purpose.
By making the lower end of the tube solid below the presser arm there is no
danger of closing the slit d or otherwise damaging the tube whilst putting on the
presser, as sometimes occurs, and another advantage is that owing to the position of
the opening being above the arm the sliver or roving is not bent backwards (as it
is when the opening is at the bottom below the arm) and as there is consequently
less strain and friction upon the roving we are enabled to wind a harder and heavier
bobbin.
Having now particularly described and ascertained the nature of our said inven
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
:-
The improvements in the manufacture of presser flyers consisting principally in
forging or otherwise forming a solid end to the hollow leg of such flyers, and
providing the hollow part of the leg just above the solid end with an opening for
the passage of the sliver or roving substantially as and for the purposes hereinbefore
described and as illustrated by the drawings annexed.
Dated this 5th day of March 1891.
