Improvements in the Manufacture of Presser Flyers.
I GEORGE FREDERICK COOKE of Kearsley Spindle and Flyer Works Farnworth near
Bolton, in the County of Lancaster Spindle and Flyer Maker do hereby declare the
nature of this invention to be as follows:-
My 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 object of
the invention being to facilitate the attaching of the "presser" to the hollow arm of
the flyer and to allow of its ready removal therefrom when required for repairs or
otherwise.
•
In the class of flyers to which my invention. relates the "presser" consists of a
vertical'rod or wire, the lower end of which is bent at right angles and is formed into
the "presser arm."
وو
The vertical rod is pivotted to the hollow leg of the flyer at the top and bottom and
by its centrifugal action as the spindle revolves it presses the free end of the "presser
arm" against the bobbin.
I braze both of the two lumps or fixings to the hollow leg of the flyer, the upper
fixing having a hole upon its upper side and the lower one a hole on its under side.
I bend the upper end of the vertical rod of the presser inwards and downwards in
the form of a hook which is supported in the hole of the upper lump or fixing, and at
the junction of the lower end of the vertical rod with the presser arm I form a pap
which comes just beneath the lower lump or fixing.
This pap (and the arm) is drilled and tapped and I fix the lower end of the presser
by passing a screw into this tapped hole so that its upper end projects into the hole
in the under side of the lower lump or fixing and forms the bottom pivot of the
" 'presser."
The screw head is countersunk flush with the surface of the ".
"
presser arm so that
there is no roughness or projection and it will be evident that by simply removing this

screw the "presser-arm can at any time be removed and replaced whilst the two
fixings always remain firmly brazed to the flyer-leg.
As a modification of the above I propose sometimes to substitute a pin for the
screw.
In this case the pin is driven tight into the hole in the lower lump or fixing; the
hole in the arm is not screwed, but a vertical slit is sawn or cut through one side
thereof, so that upon opening this slit the pin can be passed into the hole sideways, and
the slit is then closed up so as to hold the pin in its place.
I consider however that the first described arrangement is preferable.

My 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 object
of the invention being to facilitate the attaching of the "presser" to the hollow arm of
the flyer and to allow of its ready removal therefrom when required for repairs or
otherwise.
In the class of flyers to which my invention relates the "presser" consists of a
vertical rod or wire the lower end of which is bent at right angles and is formed into
the "presser arm." The vertical rod is pivotted to the hollow leg of the flyer at the
top and bottom and by its centrifugal action as the spindle revolves it presses the free
end of the "presser-arm" against the bobbin.
The nature of my invention and the manner in which it is to be performed or
carried into practical effect will be readily understood on reference to the annexed
sheet of illustrative drawings and the following explanation thereof.
Fig. 1. is an elevation of a presser flyer manufactured according to my invention
and Figs. 1 1, 2 and 3. are detached views of certain portions thereof hereinafter more
particularly referred to.
a, a is the flyer having one leg solid and one tubular as usual (see Fig. 1.)
I braze both of the two lumps or fixings b, b and c, c (see Figs. 1ª and 1') to the
hollow leg a¹ of the flyer, the upper fixing b, b having a hole upon its upper side and
the lower one c, c a hole on its under side (see Figs 1 and 1').
I bend the upper end of the vertical rod d, d of the presser inwards and downwards
(see Fig. 2 detached) in the form of a hook e, which is supported in the hole of the
upper lump or fixing b, band at the junction of the lower end of the vertical rod d, d
with the presser arm ff, I form a pap g which comes just beneath the lower lump
or fixing c, c.
This pap g, g (and the arm) is drilled and tapped and I fix the lower end of the
presser ff by passing a screw h into this tapped hole so that its upper end projects
into the hole in the under side of the lower lump or fixing c, c and forms the bottom
pivot of the "presser" f, for the screw may be fast in the lump, and work loose in the
pap:
The screw head is countersunk flush with the surface of the "presser-arm" so that
there is no roughness or projection and it will be evident that by simply removing this
screw the "presser-arm" f, f can at any time be removed and replaced whilst the
two fixings b, b and c, c always remain firmly brazed to the flyer leg a¹.
As a modification of the above I propose sometimes to substitute a pin for the screw.

page_text: In this case the pin is driven tight into the hole in the lower lump or fixing c, c
the hole in the arm is not screwed but a vertical slit ii is sawn or cut through one
side thereof as shown detached at Fig. 3. so that upon opening this split i, i the pin
can be passed into the hole sideways and the slit is then closed up so as to hold the pin
in its place. I consider however that the first described arrangement is preferable.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed I declare that what I claim is :-
In that class of presser flyers wherein the presser consists of a vertical rod or wire
the lower end of which is bent at right angles and formed into the presser arm,
brazing the top and bottom lumps or fixings on to the hollow leg of the flyer, and
providing the presser arm with a pap by means of which it is jointed to the lower lump
by a removable screw or pin substantially as hereinbefore described and illustrated
by the drawings annexed.
