Improvements in Spindles for Spinning Machines.
I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent Agents,
45 Southampton Buildings, in the County of Middlesex, 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 spindles for spinning machines and has for its object to
enable such spindles to run steadily at a high rate of speed without being affected
by the lateral pull of the driving band on the whirl. Usually the whirl is rigidly
attached to the spindle concentrically therewith and every variation in the tension
of the driving-band has a tendency to cause a lateral motion of the whirl and
spindle which tendency is resisted by the spindle-supports as bolsters and steps, but
as the spindle-supports and the bearing-surface of the spindle become worn the
disturbing effect of the driving-band becomes greater. To obviate this effect of
the driving-band on the spindle, the spindle and whirl are made in separate parts
and supported independently of each other, they being so connected that a rotation
of the whirl will produce a rotation of the spindle, while a slight lateral movement
of the whirl is not communicated to the spindle.
In the accompanying drawings,
Fig. 1 is an isometric view of a part of a spindle-rail, the bolster or spindle-
support, the spindle and whirl, constructed in accordance with the invention, a
bobbin and cop on the spindle and the hook which prevents the spindle from being
lifted in doffing;
Fig. 2, a front elevation of a part of the spindle-rail and bolster-case, the nut
which retains the bolster-case in the rail, the bolster, a part of the spindle and the
hook and a central vertical section of the sleeve which forms the lower bearing
of the body, the flange of said sleeve, the whirl and the upper part of the
bolster-case;

Fig. 4, a central vertical section of the bolster-case, bolster whirl, sleeve-bearing
and an elevation of the body of the spindle.
the
The bolster-case, A, is supported in the spindle-rail, B, in a well-known manner,
said bolster-case having an enlarged head or upper end, a, which rests upon
spindle-rail, the latter being clamped between said head, a, and a nut, a', which
turns on a threaded portion, a³, of the bolster-case against the underside of said
spindle-rail. Within a vertical opening in the bolster-case is secured the bolster, C,
the same having a central vertical opening, c, to receive the lower part of the
spindle, D, which has a running fit therein in the usual manner.
The body of the spindle, D, is of the usual form and is made in a separate piece
from the whirl, E, but is provided with the sleeve, d', which usually connects said
spindle and whirl, said sleeve serving as the lower bearing of the bobbin, F, in the
usual manner.
If desired, the bolster, C, may extend up into said sleeve, d', in a
well-known manner. The lower end of said sleeve, d', is provided with an
outwardly extending horizontal projection, d², represented as an annular flange of
about the same diameter as the whirl, E, and is provided with one or more radial

page_text: slots, a, to receive a corresponding number, of pins, e, which project upwardly from
the top of the whirl and loosely engage said slots.
The bolster, C, is provided below its upper end with a shoulder, c', represented
as a collar or external annular flange, which supports the whirl, E, said whirl
surrounding the upper part, c², of said bolster above said shoulder, c', and being
separated from the body of the spindle by said bolster. The whirl is provided
with a band-groove, e¹, to receive the driving-band in the usual manner. It is
evident that a rotation of the whirl in the usual manner will rotate the spindle, the
flange, d,-with-its-radial-slots forming one counterpart and the whirl with its
pins, e, forming the other counterpart of a clutch, but the bolster is so rigid and
the pins, e, are so loose in the slots, d³, that any lateral movement of the whirl
caused by the tension of the driving-band is not communicated to the spindle.
The hook, G, extends over the flange, d², and serves the usual purpose of
preventing the spindle from being lifted out of the bolster, C, in the act of doffing
the bobbins, and said hook may be turned in the usual manner to allow the spindle
and whirl to be removed when necessary.
The top or head, a, of the bolster-case, A, is provided in the usual manner with
a concavity, a³, to receive oil which flows down through an inclined oil-hole, a', in
said bolster-case into an oil-passage, a³, formed in either or both of the contiguous
threaded surfaces, as e³, of the bolster-case and bolster and into an annular space, a²,
between said bolster-case and bolster below said threaded surfaces and passes
through slots or holes, c, which enter the central opening, c, of the bolster to
lubricate the bearing surface of the spindle. As the spindle gradually increases in
diameter from its lower end to the top of the bolster, the rapid rotation of the
spindle will carry the oil to the top of the bolster, and throw said oil over the top
of the bolster, against the sides of the central opening, e², of the whirl, and said
central opening is "rifled" or provided with a shallow left-hand screw-thread so
that the rotation of the whirl which turns in a right-hand direction or with the
sun, carries the oil down to the bottom of the whirl and into an annular chamber, a³,
in the top of the bolster-case, said whirl being provided with a down-hanging
annular flange, 3, which extends into said annular chamber, a³, in such a manner
that oil dripping from said flange, e, and thrown outward by centrifugal force will
be caught in said chamber, as, from which it passes through the inclined oil-hole, a*,
which passes through a corner of said chamber, as shown in Fig. 4.
The above described invention is applicable to any spinning, winding, or twisting
machine in which the spindle is rotated by a whirl and band and in which it is
desirable to prevent a lateral motion of the whirl being communicated to the
spindle. Said invention also allows of the spindle being removed and replaced
without removing the band from the whirl or removing the whirl from its bearing
and thereby allows spindles of different lengths to be used with the same whirl.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, as communicated to me
by my foreign correspondents, I declare that what I claim is :-
1. The combination of a spindle and whirl, formed in separate parts, one of
which parts has vertical pins adapted loosely to engage slots with which the other
of said parts is provided, with a bolster having an internal bearing for said spindle
and an external bearing for said whirl, as and for the purpose specified.
2. The combination of a spindle and a whirl, formed in separate parts, said
spindle having a flange provided with slots, and said whirl having pins which loosely
engage said slots, with a bolster having separate bearings for said spindle and
whirl, as and for the purpose specified.
3. The combination of the bolster provided with an external shoulder, the
spindle, supported in said bolster, and a whirl surrounding said bolster and
supported on said shoulder, said spindle having a flange provided with slots and
said whirl having pins, loosely to engage said slots, as and for the purpose
described.

page_text: 4. The combination of the spindle with the whirl constructed in separate parts,.
and supported independently, and operative connections between the same, con--
structed and arranged to produce a rotation of the spindle while a slight lateral
movement of the whirl is not communicated to the spindle, all substantially as set-
forth.
