Improvements in Spindles for Spinning, Winding, or Twisting
Machines.
We, EDWARD JAY FENDERSON, of 159 Middlesex Street, Lowell, in the
County of Middlesex and Commonwealth of Massachusetts, one of the United
States of America, Machinist, and ALONZO AUGUSTUS COBURN, of 70 Rolfe
Street in said Lowell, Manufacturer of Cotton Machinery, 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 :-
Our 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, we make the spindle and whirl in separate parts
and support them independently of each other, so connecting them that a rotation
of the wheel 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 our invention, a
bobbin and cop on the spindle and the hook which prevents the spindle from being
lifted in doffing;

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 bobbin, the flange of said sleeve, the whirl and the upper part of the
bolster-case;
Fig. 3, a plan of the spindle and bolster-case and of a part of the spinning-rail ;
Fig. 4, a central vertical section of the bolster-case, bolster, whirl, sleeve-
bearing and an elevation of the body of the spindle.
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 the
spindle-rail, the latter being clamped between said head a and a nut a¹ which turns
on a threaded portion a² of the bolster-case against the under side 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 din a
well known manner. The lower end of said sleeve d' is provided with an
outwardly-extending horizontal projection, 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 dª 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 of said bolster above said shoulder and being
separated from the body of the spindle by said holster. The whirl is provided
with a band-groove, 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 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 d' 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 d' and serves the usual purpose of preventing the spindle
from being lifted out of the bolster C in the act of dofling the bobbins and said
hook may be turned in the usual manner to allow the spindle and whirl to be
removed when necessary.
passes
The top or bead a of the bolster-case A is provided, in the usual manner, with a
concavity a² to receive oil which flows down through an inclined oil-hole a' in snid
bolster-case into an oil-passage a. formed in either or both of the contiguous
threaded surfaces a' of the bolster-case and bolster and into an annular space a
between said bolster-case and bolster below said threaded surfaces and
through radial holes et which enter the central opening e 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 of the whirl,
and said central opening is
"rilled
or provided with a shallow left-hand
screw-thread, so that the rotation of the whirl, which turns in n right-hand
direction or with the sun, carries the oil down to the bottom of the whirl
and into an annular chamber in the top of the bolster-case, said whirl being
provided with a downhanging annular flange which extends into said annular
chamber a in such a manner that oil dripping from said flange and thrown
outward by centrifugal force will be caught in said chamber a", 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, we declare that what we
claim is;
1. The combination of a spindle and a 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

page_text: 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
specified.
