I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co., Patent Agents
Southampton Buildings, London, do hereby declare the nature of this invention to bo
as follows:
My invention relates to that class of spindles having a sleeve whirl, and having its
bearings combined with a bolster case or support; and it has for its object to provide
a construction and arrangement of the spindle and its bearings which shall enable the
spindle to run steadily at high speed under all the conditions occurring in practical
use, and at the same time retain the spindle in a permanent vertical position with
relation to the ring.
It is a well known fact that spindles of this class cannot be operated satisfactorily
if held in bearings that are entirely rigid and unyielding. To provide for the
necessary adjustment various plans have been shewn heretofore, as for instance;
certain forms have been constructed having step bearings loosely fitted within a bolster
case and free to move laterally with the foot of the spindle without restraint and
without limit until checked by contact with the interior of the bolster case. This
freedom of movement and the consequent contact, operate in effect as a series of
rapid blows against the foot of the spindle, inducing vibration and increasing the
wear of the bearings.
Other forms have been made with the bolster and step bearing integral and loosely
fitted within a bolster case throughout the entire length of such bearing. This form
cannot be maintained in a permanent vertical position and thereby causes great
trouble with relation to the ring.
It has been found by experience however, that these defects can be overcome, and
the desired results obtained by supporting the step bearing without lateral contact at
or near the foot of the spindle; the bearing being provided with a fixed vertical
support either from above or below, which shall be so constructed as to be able to
spring by reason of its own elasticity and thereby permit the step bearing to yield to
the lateral pressure of the foot of the spindle when acted upon by the forces developed
by the rotation of an unequally distributed bobbin load.

page_text: It has also been found that this result is rendered more complete and satisfactory
by locating the bolster bearing wholly above the bolster support or neck and con-
structing it in such a way that it also may be adapted to spring or yield by reason of
its own elasticity, and thereby conform more freely to the movements of the step
bearing below.
The step bearing is suspended within the bolster case by means of the thin con-
necting sleeve the upper end or connection of the sleeve being enlarged and closely
fitted within the bolster case and fixed therein so that it shall have its movement at
that point.
Below such fixed point the walls of this sleeve are made of such a thickness that
they are elastic or flexible and will spring sufficiently to permit the step bearing to
yield to the lateral pressure of the foot of the spindle.
It is obvious that if the step bearing were left entirely free to move laterally without
restraint as heretofore, it would strike from side to side and would lack the necessary
lateral resistance to steady the spindle against gyration. With this construction how-
ever the elastic support combines the very important and double function of permitting
the step bearing to yield to the foot of the spindle, whenever such yielding is necessary
to accommodate the spindle and its load, and at the same time the support offers
a sufficient resistance to such movement to steady the spindle against gyration
and limit the movement so that no contact can be had with the interior of the
bolster case.
In order that the full benefit of this construction may be obtained the spindle is
tapered upward to a point above the plane of the bolster neck, so that the entire bolster
bearing surface shall be located above the rigid lateral support of such neck, and the
bolster bearing is thereby not only much less dead to the pressure of the spindle than
if located within the rigid bolster neck, but it is enabled to yield slightly by reason of
its own elasticity and thus conform to the movements of the step below.
The extent of this movement required to accommodate the spindle and its load is
much less at the bolster bearing than at the neck as the centre of motion will always
be at a point within the plane of the band groove.
It is obvious that the extent or degree of flexibility to be allowed the parts
can easily be regulated in accordance with the bobbin load to be carried by the
spindle.
I do not limit myself to any particular means of securing such flexibility as I may
secure that function either by forming the parts from thin metal or by grooving them
spirally or by the use of a non-metallic and flexible material such as wood or
vulcanized fibre.
The bolster bearing is fixed to the bolster case by means of its lower end or
extension, which is driven firmly into the neck or may be screwed in if preferred.
By thus fixing the bolster to the case no looseness or play is allowed it, and as it
cannot yield at the plane of the band pull the spindle is maintained in a permanent
vertical position with relation to the ring. It also operates to support the upper end
of the bolster in a positive manner, so that no movement can be had there, except from
its own elasticity and such elasticity co-operates with the step bearing to steady the
spindle against gyration.
I do not limit myself to the application of the elastic step with such a bolster, as I
may use such improved step bearing in connection with a loose or rocking bolster
bearing if preferred.
I consider the fixed bolster bearing as the most desirable however.
The bearings have no movement in common, but are entirely independent in
operation, although formed for convenience from one piece.

page_text: I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake, and Co., Patent Agents,
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 :-
My invention relates to that class of spindles having a sleeve whirl, and having its
bearings combined with a bolster case or support, and it has for its object to provide
a construction and arrangement of the spindle and its bearings which shall enable
the spindle to run steadily at high speed under all the conditions occurring in practical
use, and at the same time retain the spindle in a permanent vertical position with
relation to the ring.
It is a well known fact that spindles of this class cannot be operated satisfactorily
if held in bearings that are entirely rigid and unyielding. To provide for the
necessary adjustment, various plans have been shown heretofore, as for instance ;
certain forms have been constructed having step bearings loosely fitted within a
bolster case and free to move laterally with the foot of the spindle without restraint
and without limit until checked by contact with the interior of the bolster case.
This freedom of movement and the consequent contact, operate in effect as a series
of rapid blows against the foot of the spindle, inducing vibration and increasing the
wear of the bearings.
Other forms have been made with the bolster and step bearing integral and
loosely fitted within a bolster case throughout the entire length of such bearing. This
form cannot be maintained in a permanent vertical position and thereby causes great
trouble with relation to the ring. It has been found by experience however, that
these defects can be overcome, and the desired results obtained by supporting the
step bearing without lateral contact at or near the foot of the spindle; the bearing
being provided with a fixed vertical support either from above or below, which shall
be so constructed as to be able to spring by reason of its own elasticity and thereby
permit the step bearing to yield to the lateral pressure of the foot of the spindle
when acted upon by the forces developed by the rotation of an unequally distributed
bobbin load.
It has also been found that this result is rendered more complete and satisfactory
by locating the bolster bearing wholly above the bolster support or neck or so that
it shall not be rigidly held above said bolster support or neck and constructing it in
such a way, that it also, may be adapted to spring or yield by reason of its own
elasticity, and thereby conform more freely to the movement of the step bearing
below.
In the accompanying drawing
Figure 1 is a sectional elevation showing the spindle in elevation, and the sleeve-
whirl, bolster-rail, bolster-case, and bearings in section.

page_text: Figure 2 is an elevation showing a modification of the step support.
Figure 3 is a sectional view similar to Figure 1, showing another modification of
the invention.
In Figure 1 it will be seen that the step-bearing a is suspended within the bolster
case b by means of the thin connecting sleeve c, the upper end or connection of
the sleeve being enlarged and closely fitted within the bolster case 6 and fixed
therein so that it shall have no movement at that point.
Below such fixed point the walls of this sleeve are made of such a thickness that
they are elastic or flexible and will spring sufficiently to permit the step bearing
to yield to the lateral pressure of the foot of the spindle s.
It is obvious that if the step bearing were left entirely free to move laterally with-
out restraint as heretofore, it would strike from side to side and would lack the
necessary lateral resistance to steady the spindle against gyration. With this
construction however the elastic support c combines the very important and doublo
function of permitting the step bearing to yield to the foot of the spindle, whenever
such yielding is necessary to accommodate the spindle and its load and at the
same time the support offers a sufficient resistance to such movement to steady the
spindle against gyration and limit the movement so that no contact can be had with
the interior of the bolster case.
In order that the full benefit of this construction may be had, the spindle s is
tapered upward to a point above the plane of the bolster neck e as shown, so that the
entire bolster bearing surface shall be located above the rigid lateral support of such
neck, and the bolster bearing d is thereby not only much less dead to the pressure of
the spindle, than if located within the rigid bolster neck, but it is enabled to yield
slightly by reason of its own clasticity and thus conform to the movements of the
step below.
The extent of this movement required to accommodate the spindle and its load is
much less at d than at a, as the centre of motion will always be at a point within the
plane of the band groove g.
It is obvious that the extent or degree of flexibility to be allowed the parts c and d
can easily be regulated in accordance with the bobbin load to be carried by the
spindle.
I do not limit myself to any particular means of securing such flexibility, as I
may secure that function either by forming the parts of thin metal, as shown in
Figure 1, or by grooving them spirally as shown in Figure 2, or by the use of a
non metallic and flexible material such as wood or vulcanised fibre.
The bolster bearing d is fixed to the bolster case by means of its lower end or
extension, h, which is driven firmly into the neck e, or it may be screwed in if
preferred. By thus fixing the bolster to the case no looseness or play is allowed it,
and as it cannot yield at the plane of the band pull the spindle is maintained in a.
permanent vertical position with relation to the ring. It also operates to support tho
upper end of the bolster in a positive manner, so that no movement can be had there,
except from its own elasticity and such elasticity co-operatos with the step bearing to.
steady the spindle against gyration.
I do not limit myself to the application of the elastic step with such a bolster, as I
may use such improved step bearing in connection with a loose or rocking bolster
bearing if preferred.
I consider the fixed bolster bearing as the most desirable however.
It will be seen that the bearings a and d Figure 1, have no movement in common
but are entirely independent in operation, although formed for convenience from one
piece.
In Figure 3, I have shown the bolster tube as composed of spirally wound wire,
whereby the step bearing a is given an elastic connection with the bolster bearing at
the point or points where it is fixed in the bolster case, and the bolster rendered more
elastic throughout, so that it may be more sensitive to the movements of the step. In
this construction I prefer to extend the bolster case b to the top of or above the bolster,
as shown at r, reducing the thickness of such extended portion, to render it elastic,

page_text: so that the relationship of the bolster to the bolster case will be substantially the same
as is represented in Figure 1, it having a fixed or rigid relation with the bolster case
only at a point substantially corresponding to the extension h in said last mentioned
Figure.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, as communicated to
me by ny foreign correspondent, I declare that what I claim is :-
First. The combination with a spindle and its sleeve whirl, of a closed bolster case
or support therefor provided with a bolster bearing for said spindle, and provided also
with an independent step bearing having an elastic extension or sleeve, fixed at its
upper end within the bolster case and adapted to suspend the step bearing within such
case and at the same time permit the step bearing to yield laterally with the foot of
the spindle.
Second. A spindle and its sleeve whirl, a closed bolster case therefor, a bolster
bearing fixed to the said case and having its bearing surface located wholly above the
plane of said case, combined with an independent step bearing suspended within the
bolster case by means of an elastic or flexible connecting sleeve fixed at its upper end
within the bolster case and adapted to suspend the step bearing in a flexible or elastic
manner, as set forth.
Third. The combination with a spindle and its sleeve whirl, of a closed bolster case
therefor provided with a compound bearing tube for the said spindle consisting of an
upper part or section fixed to the bolster case and adapted to afford a bolster bearing,
a lower part or section to receive the foot of the spindle and afford a step bearing, and
an intermediate, elastic or flexible part or section adapted to suspend the said lower
section within the bolster case and at the same time permit such section to yield
laterally with the foot of the spindle.
Fourth. A bolster tube, combined with a bolster bearing fixed therein, and a step
bearing connected with the bolster bearing by means of a spirally wound wire, as
set forth.
•
Fifth. A step bearing for spindles suspended by means of a spirally wound wire,
substantially as set forth.
Sixth. A combined step and bolster bearing formed from spirally wound wire,
substantially as set forth.
