Improvements in Spindles for Spinning and like Machines.
We, JAMES BATTERSBY, of No. 3006, Poplar Street, Book-keeper, and
BANJAMIN WOLF FLEISHER, of No. 2301, Green Street, Manufacturer, both of
Philadelphia, Pennsylvania, United States of America, 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:-
Our invention consists in providing a bobbin or cop spindle with ball bearings,
whereby it is adapted to rotate with reduced friction and with greater freedom
and rapidity.
Figure 1 represents a side elevation of a spindle embodying our invention.
Figure 2 represents a longitudinal vertical section thereof."
Figure 3 represents a transverse horizontal section on line at Figure 2.
Figure 4 represents a vertical section of a portion on an enlarged scale.
Similar letters of reference indicate corresponding parts in the figures.
Referring to the drawings:
A designates a sleeve or casing, which by means of the shoulder B and nut C or
other suitable devices, is rigidly or stationarily secured to the portion or beam D
of a supporting frame.
E designates a spindle, which is firmly connected with the bolster F, to which
the pulley G is secured, the lower portion of said spindle entering the sleeve A.
Depending from the underside of the top H of the bolster is the neck J, whose
lower edge K is bevelled or conical, and contacts with the balls L, which are
supported in a recess in the collar M, the latter being seated on the shoulder N,
in the interior of the upper end of the sleeve A, said collar M being screwed or
otherwise secured to the adjacent portion of said sleeve so as to remain stationary
therewith.
To the interior of the lower end of the sleeve is secured the collar P, which
occupies the recess Q in the sleeve; a recess in the collar has seated therein the
balls R, which rest on the bevelled or conical face S of the nut T, which is screwed
to the lower end of the spindle E, so as to rotate therewith, said nut T being
retained in position by means of the washer U and lock-nut Von said spindle.
Depending from the lower end of the sleeve A and secured thereto is the
inverted cap W, the same closing the bottom portions of the device and consti-
tuting an oil chamber.
Rising from the shoulder B is the flange W, which enters the recess X in the
underside of the pulley G, for assisting to steady the latter and connected parts
in their rotation.
It will be seen that when power is applied to the pulley rotary motion is com-
municated to the spindle and connected parts, so that the spindle rotates on ball
bearings at the upper and lower portions of the spindle, formed respectively by
the neck J, balls L and collar M and the nut T, balls R and collar P, whereby it
moves with less friction than heretofore and consequently with great freedom and
rapidity or swiftness.
In order to adapt the collar M to receive its balls L, said collar is provided with
a ring M¹ made removable so that the balls may be placed in the recess of said

page_text: collar M, after which said ring M¹ is inserted in the collar over the balls whereby
the latter are prevented from dropping-out from said recess in assembling the
parts.
The neck J and adjacent portion of the bolster F serves to retain the ring M¹
in position.
The collar P is provided with a ring V₁ similar to the ring M¹ the said ring Vi
illing the recess in the collar below the balls, it being evident that the said collar
and ring may be readily removed and replaced, the said ring when in position,
being retained by a shoulder or flange T¹ on the adjacent portion of the nut T.
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 what we
claim is:-
1st. A bobbin or cop spindle having ball bearings therefor.
2nd. A bobbin or cop spindle, and a casing or sleeve therefor in combination
with ball bearings for said spindle interposed between the same and said sleeve.
3rd. A bobbin or cop spindle, a stationary casing or sleeve, a bolster, a collar
on the sleeve, and balls interposed between said bolster and collar in contact
therewith.
4th. A bobbin or cop spindle, a stationary sleeve therefor, a bolster and a
pulley to which said spindle is secured, a neck on the interior of said bolster, a
collar on said sleeve, and balls interposed between said neck and collar.
5th. A bobbin or cop spindle, a stationary casing or sleeve, a collar on said
sleeve, a collar on said spindle and balls interposed between said collars in contact
therewith.
6th. In a bobbin or cop spindle provided with ball bearings, a collar adapted to
receive the balls formed in sections, one being removable from the other.
