PROVISIONAL SPECIFICATION,
Improvements in and connected with the Spindles of Ring Spinning
and Doubling Frames.
I, JOHN ORMEROD COTTRILL, of The Bee Hive Works, Bolton, in the County
of Lancaster, Engineer, do hereby declare the nature of this invention to be
as follows:-
My said invention relates to the spindles of ring spinning and doubling frames,
and has reference to the lubrication of spindles of the self-contained type.
In such spindles it is desirable to clean and lubricate the same without:
stopping them and for this purpose the bolster has been provided with a re-
movable oil cup, the lubricant contained therein having access to the spindle
through apertures in the footstep bearing.
My invention relates to such removable oil cups.
In carrying my invention into effect, I bore out the holster to accommodate
a tubular oil cup surrounding the footstep of the spindle. This footstep is pro-
vided as usual with suitable apertures through which the lubricant in the oil.
cup obtains access to the spindle. To provide means for preventing the escape
of lubricant I form the upper interior portion of the bolster with an annular.
lip so as to form a recess within which sits the upper portion of the oil cup. For
the ready attachment and detachment of the oil cup I form the lower portion
thereof with a quick single screw thread engaging with a corresponding thread
formed in the lower end of the bolster. The oil cup having been supplied with
lubricant is slipped within the interior of the bolster and surrounding the foot-
step. On the screw threads of the cup and bolster engaging the cup is revolved
until the upper portion enters the annular recess and the flat top of the cup
beds tightly against the flat roof of the recess.
The annular lip may be dispensed with and the flat top of the oil cup bed
against a flat roof formed in the bolster.
The bottom of the oil cup may be formed with a squared or other shaped head
so that the cup may be readily revolved by means of a key.
Dated the 26th day of August 1898.

Improvements in and connected with the Spindles of Ring Spinning
and Doubling Frames.
I, JOHN ORMEROD COTTRILL, of The Bee Hive Works, Bolton, in the County
of Lancaster, Engineer, do hereby declare the nature of this invention and in
what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement and accompanying drawings:-
My said invention relates to the spindles of ring spinning and doubling frames,
and has reference to the lubrication of spindles of the self-contained type.
In such spindles it is desirable to clean and lubricate the same without
stopping them and for this purpose the bolster has been provided with a re-
movable oil cup, the lubricant contained therein having access to the spindle
through apertures in the footstep bearing.
My invention relates to such removable oil cups.
The accompanying sheet of drawings clearly illustrates my invention.
In the said drawings.
Fig. 1 shows in elevation a self-contained spindle partly in section with my
invention applied.
Fig. 2 is a modification.

In carrying my invention into effect I bore out the bolster a of the spindle
to accommodate a tubular oil cup b surrounding the footstep e of the spindle.
This footstep is provided as usual with suitable apertures c through which the
lubricant in the oil cup 6 obtains access to the spindle. To provide means for
preventing the escape of lubricant I form the upper interior portion of the
bolster with an annular lip d so as to form a recess within which sits the
upper portion of the oil cup. The flat top of the oil cup beds against the flat
cup
roof of the recess d¹. For the ready attachment and detachment of the oil
I form the lower portion thereof with a quick single screw thread e engaging
The oil
with a corresponding thread formed in the lower end of the bolster a.
cup having been supplied with lubricant is slipped within the interior of the
bolster a and surrounds the footstep bearing c of the spindle. On the screw
threads of the cup b and bolster a engaging the cup is revolved until the upper
portion enters the annular recess and the flat top of the cup beds tightly against
the flat roof of the recess as shown in Fig. 1.
The annular lip d may be dispensed with if desired.
In this case the oil tight joint is formed by the flat top of the oil_cup_b
bedding tightly against the flat roof of the bolster a as shown in Fig. 2.
In this fig. the oil cup b (is drawn in outside view to more clearly show the quick
single screw.
When the spindles are secured to the rail in the usual manner the oil cup b)
may be readily removed, cleansed and replenished with lubricant without stopping
the spindle. The bottom of the oil cup is formed with a squared head f so that
it may be readily revolved by hand or by means of a key.
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) The improved arrangement for lubricating spindles of the self-contained
type for ring spinning and doubling frames consisting of a tubular oil cup b,
fitting within the bored out bolster a which is formed with an annular lip d
and recess d, the flat top of the oil cup entering such recess and bedding

page_text: against the flat roof thereof, the oil cup being readily attachable and detachable
by means of a quick single screw thread formed thereon engaging with a corre-
sponding thread in the interior of the bolster substantially as described and
illustrated in Fig. 1.
2) For lubricating spindles of the indicated type the oil cup 6 fitting within
the bored out bolster a the oil cup being formed with a flat top to bed tightly
against the flat roof of the recess in the bolster, and also provided with a quick
single screw thread to engage with a corresponding thread formed in the bolster
in the manner for the purposes and substantially as described and illustrated
in Fig. 2 of the drawings.
