PROVISIONAL SPECIFICATION.
Improvements in Bearings for Spindles used in Spinning and like
Machinery.
We, EZRA SYKES and DAVID SYKES, of the firm of John Sykes and Sons, of
Turnbridge Machine Works, Huddersfield, Yorkshire, Machine Makers, do hereby
declare the nature of this invention to be as follows:-
This invention refers to improvements in bearings for spindles used in spinning,
twisting, winding, and like textile machinery, and its object is to reduce friction, and
to prevent vibration, or oscillation of the spindle when rotating, whereby we are
enabled to drive the spindles at a greater speed and with less wear and tear than is
possible at present.
In order to carry out our invention when applied to spindles supported in single
bearings, we employ a metal ball which is placed in the bottom of the bearing and is
free to turn around therein. The lower extremity or foot of the spindle is flattened,
and when inserted into the bearing rests upon the metal ball in the bottom thereof,
the parts being so arranged that when the said spindle is driven, it becomes self
balancing by means of the metal ball bearing, and although driven at a higher speed
than is usual it remains perfectly true, and there is no perceptible vibration or oscil-
lation thereof. The ball being capable of turning around in any direction and
continually presenting different portions of its surface to the bottom of the spindle and
also to the sides and bottom of the cup or footstep in which it is placed, the points of
contact between the parts named being so slight that friction is thereby reduced to a
minimum. Instead of only one ball being employed, we may employ three additional
smaller balls, the sum of whose diameters equals the diameter of the large ball, which
is arranged to rest upon them, and supports the spindle as before described, or the
three smaller balls may be used alone.
In addition to placing a ball or balls in the bottom of the cup or footstep, we may
insert two or more metal balls into the cup or footstep near the top thereof, so as to
surround the spindle.
When applying our improvements to the collar and footstep bearings at present
mostly employed for supporting the spindles, we preferably use a metal ring or rings
within or between which are held a number of balls, the said ring or rings being
driven or screwed into the collar and a similar one secured in the footstep, so that the
balls, which project beyond the inner surface of the ring or rings, shall surround
and bear against the spindle, and operate as and for the purposes above set forth.
When the parts in contact with each other become worn and the balls do not abut
against the spindle, we may renew the bearings again and again by screwing down
the ring or upper ring, which forces the balls nearer the centre of the spindle and thus
renews the bearings.

Improvements in Bearings for Spindles used in Spinning and like
Machinery.
We, EZRA SYKES and DAVID SYKES, of the firm of John Sykes and Sons, of
Turnbridge Machine Works, Huddersfield, Yorkshire, Machine Makers, 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 refers to improvements in bearings for spindles used in spinning,
twisting, winding, and like textile machinery, and its object is to reduce friction and
to prevent vibration or oscillation of the spindle when rotating, whereby we are
enabled to drive the spindies at a greater speed and with less wear and tear than is
possible at present.

In order that our invention may be better understood, we will now proceed to
describe the same more fully, and for that purpose make reference to the accom-
panying sheet of drawings, wherein Fig. 1 is a vertical section of a "Rabbeth
spindle bearing, shewing the application thereto of three antifriction bowls a resting
in the bottom of a cup or thimble within the tube e The spindle d is made at its
lower end with a pivot or point, and it rests and is balanced within the conical shaped
cavity formed between the three balls as will be well understood. As the point of the
spindle is borne in the cavity left between three antifriction bowls, there is very little
friction on the spindles, consequently they can be run at a high speed with little
expenditure of power. Fig. 2 of the drawings is a section through line A B of
Fig. 1.
In Fig. 3 we have shewn the application of ball bearings placed near the top of the
tube in addition to those upon which the spindle rests, which serves to balance and
steady it. These antifriction bowls are inserted into a groove formed near the top of
the tube c, and they are kept in position by means of a collar or ring g which is driven
tightly into position. Fig. 5 is a cross section of Fig. 3 through line CD. In Fig. 4
we have shewn the application of ball bearings in the footstep e carried by the low
spindle rail, and also the application of antifriction bowls in the bearing carried by
the top spindle rail in this case the point of the spindle does not rest in the cavity
formed by the antifriction bowls, but the said bowls bear against the periphery or
outer surface of the spindle. We may, however, if required, rest the spindle shewn
in Fig. 4 upon three antifriction balls as illustrated in Fig. 1. When the parts in
contact with each other become worn, and the balls do not touch the spindle, the
bearings may be renewed as occasion requires.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that we are
aware of the Specification of the Patent of Walter Chatwood Burton No. 10,02587
and we make no claim to anything described and claimed therein; but what we
claim is :-
Firstly. The combination of antifriction balls to Rabbeth and other like spindle
bearings, as described and illustrated in the accompanying drawings.
Secondly. The combination with spindles used in spinning and other like machinery,
of ball bearings arranged at the foot and side of spindles, as shewn in Fig. 3 of the
accompanying drawings.
Thirdly. The combination with spindles used in spinning and other like machinery
of ball bearings arranged at the foot and side of the spindle, as shewn in Fig. 4 of the
accompanying drawings.
