PROVISIONAL SPECIFICATION.
Improvements in Spindle Mountings for Spinning Machinery.
I JOHN MUIR HETHERINGTON of the Vulcan Works, Pollard Street, Manchester in
the county of Lancaster, Machine Maker do hereby declare the nature of this Invention
to be as follows:-
My Invention relates to the cases wherein the spindles of spinning machinery are
mounted in bolsters within which bolsters the spindles rovolve without the necessity
for extraneous bearings. In some arrangements the spindle has been so mounted as
that the part in which the spindle revolved has had an amount of freedom that is to
say it has not been rigidly fixed the intention being that it should accomadate itself
to the slight oscillations of the spindle when in rapid revolution, increased steadiness
being the result. In such cases the bearing for the spindle has been formed in one
part which has been made resilient or has been mounted within an elastic seating of
textile material or the circulating oil has served as an elastic seating. In order
principally to increase the steadiness of rotation of the spindle I mount the spindle
in two parts an upper bearing being formed in one part and a footstep bearing in the
other part The footstep part is suspended within the bolster by means of a collar or
of projections or of other means and extends downward into the oil reservoir formed
in the bolster. The upper bearing part is mounted within the upper part of the
bolster and rests upon the upper end of the footstep part or upon an interposed elastic
washer or spring or is separated by an intervening space as considered to be most
suitable. This upper part not rigidly fixed within the bolster but has a suitable
amount of play or freedom and may have an elastic seating or enclosure as for example
an envelope of cloth or textile material may be interposed between the said part and
the inner surface of the bolster or metal springs may be employed to impart elasticity
to the movements of the part or the downward flow of oil between the said part and
the said inner surface may be depended upon to furnish an elastic cushion. I prefer
in all cases to provide for a circulation of lubricant upward through the upper bearing
and downward between the upper bearing part and the bolster.

I JOHN MUIR HETHERINGTON of the Vulcan Works, Pollard Street, Manchester, in
the County of Lancaster machine maker 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 and accompanying drawings:-
-
My Invention relates to the cases wherein the spindles of spinning machinery aro
mounted in bolsters within which bolsters the spindles revolve without the necessity
for extraneous bearings. In some arrangements the spindle has been so mounted as
that the part in which the spindle revolved has had an amount of freedom-that is to
say it has not been rigidly fixed-the intention being that it should accomodate itself
to the slight oscillations of the spindle when in rapid revolution increased steadiness
being the result. In such cases the bearing for the spindle has been formed in one
part which has been made resilient or has been mounted within an elastic seating of
textile material or the circulating oil has served as an elastic seating. In order
principally to increase the steadiness of rotation of the spindle I mount the spindle in
two parts an upper bearing being formed in one part and a footstep bearing in the
other part each part being seated or mounted to have an amount of freedom of vibration
independently of the other.
The
In order that the nature of my invention and the manner in which I propose to
carry the same into effect may be fully understood I will describe the said invention
with reference to the accompanying drawings wherein are illustrated two examples of
spindles mounted in accordance with my invention. In the said drawings a is a
spindle curtailed in length for want of room is the bolster and c is the wharve. In
Figs. 1 and 2 the parts in which the spindles revolve are represented in vertical
section. In Fig. 1 the bolster is extended downward below the spindle rail and is
bored out to receive the parts in which the spindle bearings are formed. The said
bearings are formed in two parts d and e which for sake of distinction I will respectively
term the upper and tho lower bearing. The bore of the upper part of the bolster is
larger in diameter than that of the lower part so that a shoulder is formed at
lower bearing e is formed with a collar which rests upon the said shoulder the bearing
being thereby suspended in the chamber which is formed by the bore in the lower
part of the bolster. The space around the lower bearing constitutes a reservoir for
lubricant. In the bearing e is formed the footstep bearing. The upper bearing is
bored to suit the spindle and is turned to be an easy or slightly shaking fit in the
upper part of the bolster so that there shall be space for a film of oil between the said
bearing and the bore in the bolster. In the drawing this space is exaggerated in
width. The two bearings are prevented from revolving by suitable means.
In the
example each bearing is provided with a projecting key which when the bearing is
dropped into its place enters a groove formed in the bore of the bolster. It is intended
that oil from the chamber shall circulate through the bearings oil entering the lower
bearing through oil holes flowing upward through both bearings and overflowing at
the top of the upper bearing. The oil returns through the slight annular space
between the upper bearing the shoulder on the lower bearing and the bore of the
g

page_text: bolster and interposes a film of oil between the bearings and the bolster. To facilitate
the flow of oil the bearings are or may be suitably grooved and perforated. In the
example the upper bearing is grooved and the groove opens out at d¹ so that the oil
can flow out of the groove into the annular space which surrounds the upper reduced
end of the bearing and return as aforesaid. The part e being suspended by its upper
end is free to vibrate to some extent independently of the part d but I do confine
myself to the manner of suspension so long as each bearing part is so mounted as to
be free to vibrate to some extent independently of the other part. In the example
illustrated by Fig. 2 the part e in which the footstep bearing is formed is extended
upwards so as to partly enclose the upper bearing piece d. The upper end of the
tubular part e is bored to receive the bearing d which is turned to be an easy or
shaking fit in its seating in the part e as mentioned with reference to the fitting of the
part d'in Fig. 1. The footstep part e is suspended by its upper end so as to have a
limited amount of freedom of oscillation but is prevented from revolving. Fig. 3
illustrates the means adopted in the example for preventing rotation. The upper end
of the tube e is formed with a shoulder which rests at e¹ upon the margin of the
chamber which is bored in the holster and upon the same end of the tube are formed
two lugs which enter recesses in the bolster. The upper end of the bearing dis
provided with four lugs which enter notches cut in the upper end of the tube e the
said bearing being thereby suspended and at the same time prevented from revolving.
I do not confine myself to the formation illustrated by Fig. 3. Although I have
found that a film of oil between the part d and its seating imparts an amount of
restricted freedom to the said part which has a beneficial effect in imparting steadiness
to the motion of the spindle I may increase the freedom of the said part d in either
of the examples by surrounding such part with an envelope of clastic material such
for example as cloth or textile or felted material or of cork or other suitably elastic
material or I may form a seating for the said part of pieces of cork or of a suitably
clastic material or of metal springs and also if preferred the part e in either example
may be suspended by its upper end in or upon an elastic seating. I may employ the
loosely fitting or elastically seated upper bearing part d in cases wherein the part e in
which the footstep is formed is rigidly attached to the fixed bolster or consists of a
downward extension of the same.
Having now particularly described and ascertained the nature of the said invention
and in what manner the same is to be performed I declare that what I claim is :-
(1) The combination of parts formed fitted and arranged substantially as and for
the purpose set forth and indicated hereinbefore and in the accompanying drawings.
(2) In mountings for the spindles of spinning machinery the upper and lower
bearing pieces d and e made in separate parts the part e being suspended by its upper
end and the part being loosely fitted in its seating in combination with arrangements
for obtaining a flow of lubricant between the part d and the bore of the part in
which it is seated substantially as and for the purpose set forth and indicated.
(3) In such mountings an upper part constituting the upper bearing for the spindle
and a lower part formed in a separate piece and provided with a footstep bearing the
two parts having an amount of freedom to vibrate independently of each other
substantially as set forth.
(4) In such mountings the formation of the upper bearing in one part and the
footstep bearing in another part the upper bearing part being clastically seated or
being loosely fitted in a seating without freedom of revolution substantially as and for
the purpose set forth and indicated.
