Improvements relating to Spindles for Spinning and Twisting Frames.
I, LUCIEN ERNEST GILLON of Barentin (Seine Inferieure) in the Republic of
France, Spinner; 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 a novel mode of mounting the spindles of spinning
and twisting frames, the object being to avoid the waste of lubricant at present
experienced, and to keep the bearings clear from fibre and dust, liable to accumu-
late on, and retard the free rotation of the spindles.
In the accompanying drawing, Figure 1 shews, in elevation, a flyer spindle of
a spinning frame mounted according to my invention, the bearing, footstep, and
rails, together with the novel parts, being in section, and Figure 2 is a partial
external view of the same. The spindle which is selected for illustration is an
ordinary spindle such as is used for dry spinning frames for flax, hemp, or jute,
having a taper or conical neck, which fits the ordinary brass conical bearing,
but my invention is equally applicable to spindles with parallel necks. A (Figure 1)
is the flyer spindle, formed with a conical neck a. B is the brass bearing carried
by the bearing rail, and held in place by an adjustable hook b. In this bearing,
which is formed as usual to receive the lubricant, the spindle rotates, extending
down from the bearing B, is a tube C, forming part therewith, and surrounding
the lower end of the tube C is a short tube D, for the purpose to be presently
explained. E is the whorle keyed to the spindle A, and slotted throughout its
length at e, so as to form a passage, or passages, for the lubricant escaping from
the bearing B. The spindle A is carried by a footstep F of the usual construction,
and fitted to its cover is a tube G, which reaches up to the whorle, and overlaps
a tubular extension el on the underside of the whorle. An annular groove is
formed in the top and bottom of the whorle. In the upper groove, the tube I
rests, and into the lower groove, the tube G projects. From this description it
will be seen that there is a covered passage extending from the bearing B to the
footstep F. The lubricant, therefore, escaping from the bearing B, instead of
being wasted, will flow slowly down into the footstep, thereby lubricating the
spindle foot, before escaping from the footstep. Thus, the spindle will be efficiently
lubricated without waste of lubricant. As the spindle is covered from the bear-
ing B to the footstep F by the stationary tubular casing extending from the
bearing B to the whorle E, and from the whorle E to the footstep F, no portion of
the rotating spindle below the bearing bar will be exposed to the dust and
floating fibres surrounding the spindles. The tendency, therefore, of the spindles.
in their rotation, to collect the floating matters in the atmosphere, will be avoided,
and as no dust or fibres can accumulate thereon, the liability of the bearing
surfaces to become clogged will be removed, which clogging seriously retards the
rotation of the spindles, or increases the stress employed to drive the spinning
frame. The tube D which bears upon the whorle E is free to slide longitudinally
over the tube C, it being provided internally with a pin d, which takes into a
longitudinal slot e in the end of the tube C. The object of this arrangement is

page_text: to provide for the vertical adjustment of the conical bearing B, when the tendency
of the spindle to rattle necessitates the readjustment of the conical surfaces
relatively to each other. When this adjustment takes place, the distance between
the whorle and the bearing will be contracted, which is provided for by the
sliding of the tube at D 'to a corresponding extent on the end of the tube C.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:
The means above described for enclosing flyer spindles, and providing a passage
for conducting the lubricant from the spindle bearings to the footsteps, as and for
the purpose above set forth.
