PROVISIONAL SPECIFICATION.
Improvements in Flyer Machinery for Drawing, Spinning, and
Twisting Fibrous Material.
We, WILLIAM WADSWORTH, of 13, Southfield Square, Bradford, in the County
of York, Spinner, and RICHARD HARTLEY, of Farnhill, Kildwick, in said
county, Manager, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in that class of flyer machinery for
drawing, spinning, and twisting fibrous material in which the flyer is inverted that
is to say the arms or wings of the flyer point upwards instead of downwards and
the object of the invention is to facilitate lubricating the flyer bearing as well as
economise the lubricant.
For this purpose the driving wharle or pulley is mounted upon the top of a
comparatively long sleeve secured to the base of the flyer. This sleeve is mounted
upon a hollow stationary stud through which the spindle carrying the bobbin or
its equivalent, is passed. An outer sleeve or covering is formed on or secured to
the lower end of the said hollow stud by an oil tight joint, and this outer sleeve is
sufficiently large to leave an annular oil space between it and the sleeve secured to
the flyer.
By this arrangement the bearing of the sleeve (secured to the flyer) upon the
hollow stud is practically immersed in oil and such sleeve may have holes formed
in it or other provision made to facilitate the free admission of the oil from the
above mentioned annular space to the bearing of the sleeve upon the said hollow
stud.
As a modification the bearing of the sleeve secured to the base of the flyer
may be formed in the interior of the said outer sleeve and an annular oil space
left between the interior of the inner sleeve and hollow stud.
A tube may be used to support the bobbin or its equivalent when a light "drag"
is required. This tube is normally supported by its blind end resting upon the
top of the spindle but a disc is provided upon the spindle below so that by placing
a suitable washer upon said disc the bottom of the tube rests thereupon and the
drag" is increased.

Improvements in Flyer Machinery for Drawing, Spinning, and
Twisting Fibrous Material.
We, WILLIAM WADSWORTH, of 13, Southfield Square, Bradford, in the County
of York, Spinner, and RICHARD HARTLEY, of Farnhill, Kildwick, in said county,
Manager, 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 improvements in that class of flyer machinery for
drawing, spinning and twisting fibrous material in which the flyer is inverted that
is to say the arms, or wings of the flyer point upwards instead of downwards and

page_text: the object of the invention is to facilitate lubricating the flyer bearings as well as
economise the lubricant.
T.
For this purpose the driving wharle or pulley is mounted upon a comparatively
long sleeve secured to the base of the flyer. This sleeve is mounted upon a
hollow stationary stud through which the spindle carrying the bobbin or its
equivalent is passed. An onter sleeve or covering is formed on or secured to the
lower end of the said hollow stud by an oil tight joint, and this outer sleeve is
sufficiently large to leave an annular oil space between it and the sleeve secured to
the flyer.
Reference is to be had to the accompanying sheet of drawings forming a part of
this Specification, in which similar letters of reference indicate corresponding parts
in each of the figures.

Figure 1, represents an elevation of a flyer and spindle mounted in accordance
with our invention. The lower end of the spindle is broken away.
Figure 2, represents a similar view in section with the spindle represented
raised by the lifter plate and a portion of the latter is represented with the spindle
attached.
The hollow stud A is secured by the nut B in a hole in the top rail C (a portion
only of which is shown) of the spinning frame and the spindle D passes freely
through the hole a through the stud and is fixed by the nuts F, F, or in any other
convenient manner, to the lifter plate G, a portion only of which is shown... The
flyer H is fixed upon the top of the sleeve J mounted upon the hollow->stud A, so
as to be free to revolve thereon, and the driving wharle K'is fixed upon the sleeve.
Figure 5, is a separate sectional view of this sleeve-and, wharle. An outer
sleeve L is secured upon the base of the stud A and forms an oil, tight joint:
therewith leaving an annular space N above. The upper end of L extends up
into a recess O formed in the underside of the wharle K, Figure 4, represents a
separate sectional view of the stud with the outer sleeve L mounted therein.
Figure 3, is a cross section of the same.
'
In practice the: cup formed by the annular space N is more or less filled with a
suitable lubricant and the rotation of the spindle causes the lubricant to pass up
between the stud and the interior of the sleeve J and thus efficiently: lubricating
the full length of the bearing so long as any appreciable quantity of lubricant
remains in the annular space.
***37
We have not found it necessary but it may be advisable to form one or more
holes R (Figure 5) through the sleeve below the level of the lubricant.
As a modification the bearing of the sleeve secured to the base of the flyer may
be formed in the interior of the said outer sleeve and an annular oil space left
between the interior of the inner sleeve and hollow stud but such an arrangement
requires slightly more driving and is otherwise not quite so satisfactory...)
fi:
The bobbin. is mounted upon the top of the spindle and rests upon the disc or
shoulder piece S fixed. upon the spindle. Washers may be used. in the ordinary
way introduced between the underside of the bobbin and S to regulate the "drag."
Or when a light drag is required the bobbin may be mounted upon a tube T
(shown in section in Figure 1) loosely fitting the top of the spindle and having a
blind top resting upon the more or less pointed end U of the spindle. The tube
has a circular flange V at the bottom to support the bobbin, and washers may be
introduced between this flange and the shoulder S to increase the drag.
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:
!!! 'J.
1. A spinning device of the inverted flyer type, consisting of a flyer mounted
upon a rotary sleeve supported by a hollow stud and having the bobbin spindle
passing through said stud and flyer and free to be moved longitudinally therein,
substantially as herein shown and described.
.
2. The combination with a spinning device of the inverted flyer type having the

page_text: flyer mounted upon a rotary sleeve with the bobbin spindle passed through it and
free to be moved longitudinally therein, of an annular oil space arranged
substantially as herein shown and described.
3. The combination with an inverted flyer, having the bobbin spindle free to
move longitudinally in relation to the flyer, of the tube T arranged substantially
as herein shown and described and for the purpose specified.
