IMPROVEMENTS IN SPINDLES AND BOLSTERS FOR SPINNING MACHINES
Year: 1886

page_text: I, HERBERT JOHN HADDAN, of 67, Strand, in the County of Middlesex, Civil
Engineer, do hereby declare the nature of this invention for IMPROVEMENTS IN
SPINDLES AND BOLSTERS FOR SPINNING MACHINES, a communication to me from
abroad by Eva Colby, of 22 Manahan Street, Lowell, Massachusetts, one of the
United States of America, Widow, and in what manner the same is to be performed
to be particularly described and ascertained in and by the following statement:-
The objects of this invention are to simplify and lessen the cost of construction
of the devices in question, to more effectively lubricate the spindle, and so construct
and support the spindle and bolster bearing that the former may be run at high
speed, without vibration.
This invention can be best understood by reference to the accompanying drawings
in which is shown a means for carrying it into effect.
Figure 1 is a vertical section of a bobbin spindle and bolster, embodying this
invention.
Figure 2, is a perspective view of a section of the bolster and supporting parts.
Referring to the drawings, A indicates a portion of the rail of a spinning frame,
Ba spindle adapted to be rotated by the whirl C which is attached thereto, and
D the bobbin carried by the spindle.
The
The bearing for the spindle is furnished by the bolster tube E, and a step to
properly support the lower end of the spindle is also provided, preferably by
inserting in the lower end of the bolster E, a vertically adjustable plug e.
bolster is supported by a surrounding tube F of greater diameter with which it is
connected by a thin horizontal web f.
It is preferred to connect the web f with the bolster E at about the middle of
the latter and to place the whirl C carried by a downwardly extending sleeve C¹,
in substantially the same horizontal plane as the web. It will be seen that by this
arrangement, while the bolster at its upper and lower ends may be somewhat
deflected from the axis of the supporting tube F and thus accommodate itself to
the spindle, the web ƒ forms at the centre of resistance of the bolster a bearing
which is unyielding laterally, so that the bolster as a whole does not change its
Paine B1

in line with the immovable portion of the bolster E, and therefore does not affect
the yielding action of the bolster.
It is preferred to construct the supporting tube F, bolster E and web f in one
piece, the annular chambers G and H being formed in casting or bored out. The
attachment of these parts to the rail A may be effected by a screw I, which passes
through the rail and engages with the supporting tube F.
It is preferred to make the screw I; with a chamber i to receive the lower end of
the bolster. Besides thus enabling the latter to be made of greater length and to
extend down to or below the upper side of the rail A, making the device more
compact, an oil cup is provided for lubricating the lower end of the spindle. This
is effected through a hole e¹ in the lower end of the bolster. The oil entering the
bolster by the hole e¹ is carried around and up by the action of the spindle and
overflows from the upper end of the bolster E into the chamber G. Thence it passes
through perforations in the web f into the lower chainber H and cup i again, thus
effecting a constant and thorough lubrication of the spindle. To prevent the oil
as it issues from the upper end of the bolster from being forced over the top and
onto the outside of the tube F, the spindle is provided with a flange or collar b.
The spindle B may fit the tube E for the whole length of the latter, or it may
be tapered more than the said tube and fit the latter only at its upper end, thus
giving the lower end of the spindle some freedom of lateral movement on the slip.
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:-
1. A supporting tube and a bolster tube connected by a thin transverse web,
substantially as set forth.
2. A supporting tube and a bolster tube connected by a transverse web at the
middle of the bolster tube, substantially as set forth.
3. A supporting tube and a bolster tube formed in one piece and connected by
the transverse web f, substantially as set forth.
4. The combination with the spindle of a supporting tube and bolster tube
connected by a transverse web, and a whirl attached to the spindle and situated,
substantially in the plane of the web, as set forth.
5. A supporting tube and a bolster tube connected by the web f, the bolster
tube being provided with the adjustable step e in the lower end thereof, sub-
stantially as set forth.
6. A supporting tube and a bolster tube connected by the transverse web f, in
combination with the screw I, adapted to engage with the supporting tube, and
having the chamber i, substantially as set forth.
