Bearings of Spindles and for Attaching Flyers thereto.
I JAMES MARSH of number 12A Park Parade, Ashton-under-Lyne in the County
of Lancaster Machinery Agent do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN THE METHOD OF AND MEANS FOR LUBRICATING THE
BEARINGS OF SPINDLES AND FOR ATTACHING FLYERS THERETO to be as follows:-
--
My Invention relates principally to the lubrication of the spindles of the
machinery used in the preparation, spinning and doubling of cotton and other
Textile materials. The said spindles revolve on vertical or inclined axes and
owing to the great increase in the speed of revolution it is a matter of importance
that the bearings should be well supplied with lubricant. In most cases these
spindles revolve in upper bearings or bolsters and in bottom bearings or footsteps.
To lubricate the upper bearings I apply an oil cup below the bolster the said oil
cup being formed with an exterior annular chamber into which the oil has access.
This outer chamber is formed with a lip which projects inward and which may
also project downward to retain the oil. I prefer to provide the outer chamber
with a cover which is slit so as to have an amount of spring the lip of the chamber
being formed with a groove into which the cover is sprung. The bottom of the
bolster extends nearly to the bottom of the inner cup. The lubricant ascends the
bearing and overflowing at the top is returned outside the bearing to the cup.
When the spindle is revolving rapidly the oil lies into the outer chamber wherein
the dirt is deposited the clean oil returning to the inner cup to lubricate the
bearing at te times when the rapid rotation ceases. At the upper end of the
bolster I form an oil cup or recess to receive the overflowing oil and this I provide
with a cover which has an upward tubular extension to the top or to a point a
little above the top of the bolster this extension clearing the bolster sufficiently to
provide a passage for the returning oil. This tubular part is also extended
downward nearly to the bottom of the oil cup which has a communication with
the lower oil cup herein before described. For some purposes the said cover may
be formed with a flange on which the bobbin may rest and to prevent the cover
from being lifted off when doffing I spring a split ring into a groove turned in the
upper end of the bolster,

page_text: To lubricate the footstep bearings I provide an oil trough or receptacle which
may serve for but one spindle or for a number of spindles. Above the footstep is
an oil cup from which a passage extends to the said oil trough. A second passage
extends from the trough to the bottom of the bearing. By preference these
passages and the oil trough are so arranged as that the oil descends from the
trough to the bearing and after ascending to the oil cup descends to the trough in
which the dirt will to a great extent be deposited. The dirt in the trougli and
also in the aforesaid annular chamber can readily be removed without dismounting
the spindle. I provide the oil trough with a hinged cover and in some cases
I provide this cover with a cup communicating with the trough below so that the
latter may be supplied with oil without raising the cover. For some purposes
I apply a similar oil trough to the upper bearings the passages being so arranged
as that the overflowing oil passes into the trough and is returned to cups below
the bearings. In some cases I cut a spiral groove in the bearing and the spindle
the groove in one part being a right hand and in the other part a left hand spiral
whereby the oil is caused to circulate In cases in which an oil cup is secured to
the lower ends of the bolster I form the said cup in one piece with the bolster and
provide it with a cover which can be lifted to furnish access to the cup for
cleansing and in the cases of mule spindles I extend this cup upward and steady
the upper end by means of a rail or bracket. In cases wherein flyers are attached
to the spindles I dispense with the screw thread and employ a split ring and
groove attachment the end of the spindle being squared or flattened to furnish the
driving connection.

My Invention relates principally to the lubrication of the spindles of the
machinery used in the preparation, spinning and doubling of cotton and other
textile materials. The said spindles revolve on vertical or inclined axes and
owing to the great increase in the speed of revolution it is a matter of importance
that the bearings should be well supplied with lubricant.
My Invention will be best described with reference to the accompanying
drawings wherein Fig. 1 represents a Throstle Spindle mounted in bearings
constructed in accordance with my Invention. In the said Fig. a is the upper
bolster or bearing separately represented by Fig. 2, b. is an oil cup which is secured
to the spindle and c. is the foot-step or bottom bearing the said bearings being

which the lower end of the bolster projects and with an outer annular chamber b².
The cover bs is soldered or otherwise tightly secured to prevent the escape of oil.
At the upper end of the bolster a second oil cup al is provided with a cover a²
which is held in position by the spring or elasticity of the cup which has slits in
its edge as shown at Fig. 2. A passage x. in the bolster conveys the oils upplied to
the upper cup into the lower cup the oil having access through an aperture into
the outer cup. During the revolution of the spindle the oil rises in the bearing
and descends through the said passage x. into the chamber 61. The outer cup
serves to retain deposit which determines into the said cup by reason of the rapid
revolution of the cup the clean oil flowing back to lubricate the spindle on the
rapid revolution ceasing. In place of providing the cup b2 with a cover I may
form it with an inwardly projecting lip as indicated in Fig. 3. The footstep is
also formed with a double chambered oil cup. The oil rising in the bearing into
the inner cup c¹ flows through an aperture into the outer cup c² whence it descends
through a second passage c³ to the bottom of the bearing the dirt settling in the
outer cup. Figs. 4 and 5 illustrate slight modifications in the formation of this
double chambered foot step the circulating action of the oil being the same in all
The flyer is secured in an improved manner as shown in Fig. 1 to
facilitate doffing. I turn a groove in the upper end of the spindle and into this
groove I spring a split ring d. which when the flyer is pressed down into its place
expands into a recessed annular chamber formed in the eye of the flyer. This
construction enables the flyer to be quickly lifted off and replaced. The upper
0 end of the spindle is squared or flattened or to prevent the flyer from revolving.

revolution of the lower cup has a tendency to clear the oil by causing the dirt
to be deposited as in the case of the corresponding cup in Fig. 1. A ring i
sprung into a groove in the spindle prevents the tube e¹ from being lifted
off the spindle in the doffing operation. Fig. 7 illustrates a slight modification

Fig. 9 being a plan of the upper oil cup and trough and Fig. 10 a plan of the
footstep trough. In this example the upper cup a¹ is provided with an outer
trough a into which the oil is introduced. The oil passes from this trough into
the cup a¹ and has access from thence to the bearing in the bolster as in the
preceeding examples. The outer trough a² is by preference provided with a
hinged cover a³. The footstep bearing is similarly provided with an outer oil
trough f. from which the oil is supplied to the footstep. Above the footstep is a
chamber g. into which the oil rises and from which it flows back into the outer
trough. In both cases the dir an be readily removed from the outer troughs
without disturbing the spindles. The arrangement as illustrated is suitable for
mule spindles the oil troughs being single or one trough serving for two or more
spindles. In some cases I extend the oil cup or chamber g. upward nearly to the
whirl and steady the upper end of such cup by means of a rail in the manner
indicated in Fig. 11 wherein h. represents the said rail. Instead of the said rail h.
a supporting bracket may extend from the upper rail. Fig. 12 illustrates a further
modification wherein an oil cup to supply lubricant to the footstep bearing is
formed in one piece with the bolster. In the said Fig. k. is the bolster and is a

also at the part which revolves in the upper bearing and in the said upper bearing
is also cut or formed a spiral groove but in the case of these two upper spiral
grooves one is a right hand spiral and the other a left hand spiral. These
grooves assist in lifting and circulating the oil.
