COMPLETE SPECIFICATION.
Improvements in Spindles for Spinning Machines.
1, HERBERT HORTENTIOUS HAM, of 2 Arcade Street, Boston, in the County
of Suffolk, and State of Massachusetts, United States of America, Gentleman,
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 relates to spindles for spinning machines, more particularly to
the whirl thereof, and consists in the novel features of construction and relative
arrangement of parts hereinafter fully described in the Specification, clearly
illustrated in the drawings, and particularly pointed out in the claims.
Reference is to be had to the accompanying sheet of drawings forming a part
of this application in which like characters are used to indicate like parts wherever
they occur.
Fig. 1 represents in vertical sectional view a spindle constructed in accordance
with my invention.
Fig. 2 represents a detail view of the bearings between which and the whirl the
balls are arranged.
As the bolster rail and bolster case form no part of my invention I have not
illustrated them in my drawing, but only the bolster itself, the whirl and the
spindle.
The bolster a is provided with the usual small aperture or opening a¹ in which
the spindle or the bearing for the spindle is arranged. The bolster is provided at
its lower part with the usual screw threads a² with which it may be united with a
bolster case, not shown. Near its upper portion the bolster is formed with a
flange as having a depression a* on its upper side. b represents a detachable part
of the bolster provided with screw threads 6' and an internal bore 12. These
screw threads, as shown, engage similar screw threads on the inside of the main
part of the bolster. The part b has an outwardly projecting Hange 6³, and an
upwardly projecting hub 64. Secured to this flange by a pin 62 is a boss c screw
threaded upon its upper end as at c'. This boss is provided with a ball bearing
surface c² on its upper side. d represents a whirl provided near its ends with ball
bearing grooves d and with pins d' arranged to engage a collar f¹ upon a spindle f.
The spindle frests in the bore of the detachable part 6 of the bolster and is turned
by means of the pins. c represents a collar provided on its under side with a ball
bearing groove c. In assembling the parts the boss c is slipped down upon the
part 6 and secured thereto. The balls rare arranged between the bearings on the
lower part of the whirl and said boss. The balls are then dropped into the bearings
in the upper part of the whirl and the collar c screw threaded on its inside
engaging the screw threads on the boss c is then turned down until the parts are
bound together in any desired degree of firmness. A washer squared on one
side as his slipped down on the screw threaded end of the boss, and the squared
part of the washer engages a portion 10 on the boss in order to prevent the washer
from turning. A lock nut c¹ screw threaded upon its interior is then fitted upon
the end of the boss c as shown in order to retain the parts in place. Preferably
the collar fits in a recess d in the whirl. By constructing the bolster in two
parts the ball bearing whirl and the part of the bolster can be sold as separate
articles and manipulated without disturbing the boss.

page_text: From the foregoing it will be seen that by my invention a. decided step in
advance has been taken in the spinning industry. By the use of the ball bearings
on the whirl the power required is materially diminished.
I do not desire to limit myself to any particular construction of the bearing for
the boss nor with the arrangement of the whirl or the bolster. My invention
consisting broadly of a combination of a bolster, a whirl and ball bearings formed
on said parts and balls arranged in said bearings.
The lower end of the spindle may, if desired, be mounted to turn in a step a
that is arranged in the lower part of the bolster. The collar c¹ and the lock nut c¹2
may be provided with the usual openings r in which a spanner may be fitted for
turning these parts. The spindle and its associated parts being constructed and
arranged as described and power applied to the whirl as shown, the spindle will be
caused to rotate by means of the pin d engaging the collar f¹ by reason of the
ball bearings. There is but a slight friction between the parts, and the power
required to operate the spindle is exceedingly small. The connection between the
pins d² and the collar is preferably as is shown in the drawing where a collar is
illustrated as having slots 2 in which the pins d² are arranged. With this
construction provision is made for a lateral play of the collar upon the whirl.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. In combination a bolster and whirl, said parts being formed upon opposing
faces with ball bearings and balls mounted in said bearings, substantially as and
for the purpose described.
2. In combination a bolster, a boss mounted upon said bolster and secured
thereto, a ball bearing surface upon the lower part of said boss, a whirl mounted
upon said boss and provided with ball bearings on its upper and lower side, a collar
provided with a ball bearing upon its under side and secured at the upper end of
said boss, and balls arranged between the bearings on said boss and collar and the
corresponding bearings on said whirl, substantially as and for the purpose
described.
Dated this 24th day of May 1895.
