PROVISIONAL SPECIFICATION.
Improvements in or applicable to the Rollers of Drawing, Slubbing,
Spinning, and other like Machines used in the Treatment of
Fibrous Materials.
I CURSETJEE CAWASJEE FAUZDAR of Hubli, Dharwar, Bombay Presidency,
India, Mill Manager, do hereby declare the nature of this invention to be as
follows:-
My said invention relates to improvements in the rollers of drawing slubbing
intermediate spinning or other machines used in drawing spinning or twisting
fibrous materials such as cotton and has for its principal object to provide continuous
automatic lubrication for such rollers.
When applying my said invention to what are commonly known as loose boss
rollers in which a loose sleeve revolves freely on an inner shaft or axle I make
the said axle hollow so as to form an oil reservoir. The walls of the said hollow
axle are perforated by one or more fine holes or ducts through which the oil is
discharged or drawn by the revolving outer shell. By this means a continual
supply of oil is supplied between the inner surface of the loose boss and the outer
surface of the shaft or axle on which it is mounted.
To prevent lateral displacement of the loose boss when the roller is removed I
provide the loose boss with a pin screw or projection the inner end of which takes
into a cylindrical groove turned in the axle. A longitudinal groove extending
from the said cylindrical groove to the end of the axle enables the loose boss to be
slid into position. It cannot however be displaced longitudinally unless the afore-
said inner projection is purposely placed opposite to the longitudinal groove.
In the case of solid rollers working in bearings at or near the ends the minute
perforations of the oil reservoir are placed in such a position as to discharge the
oil between the roller and the bearing in which it works.
For closing the oil reservoir and enabling it to be filled I use in some cases a
ball valve kept automatically closed by a spring and which can be readily opened
by the insertion of the point of a funnel or oil can.
In other cases I use a screw
or plug in lieu of an automatic valve.
The oil reservoir may extend continuously from end to end or may be divided
into two reservoirs.

Improvements in or applicable to the Rollers of Drawing, Slubbing,

Fibrous Materials.
I CURSETJEE CAWASJEE FAUZDAR of Hubli, Dharwar, Bombay Presidency,
India, Mill Manager, 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 and accompanying drawings
My said invention relates to improvements in the rollers of drawing slubbing
intermediate spinning or other machines used in drawing spinning or twisting

page_text: fibrous materials such as cotton and has for its principal object to provide
continuous automatic lubrication for such rollers.
When applying my said invention to what are commonly known as loose boss
rollers that is to say those in which a loose sleeve revolves freely on an inner
shaft or axle a as shown in Figure 1 which is partly in section I make the said
inner axle hollow so as to form an oil reservoir the walls of which are perforated
as at m m by one or more fine holes or ducts through which the oil is discharged
or drawn by the loose boss b as it revolves. A continual supply of oil is thus
delivered between the inner surface of the loose boss band the outer shaft of the
axle a.
To prevent the displacement of the loose boss b when the roller is removed I
provide it with a pin or screw d the inner projecting end of which takes into a
cylindrical groove turned in the axle. A longitudinal groove d² extends from
the said cylindrical groove to the end of the axle When putting on the loose
boss 6 the point of the pin d is slid along the groove d². The loose boss cannot be
slid off unless the point of the pin d is brought in line with the groove d².
In the case of solid rollers as shown in Figure 2 that is to say such as have no
loose boss and which work in bearings in or near the ends the minute oil ducts m
are placed in such positions as to deliver the lubricant between the journal and its
bearing.
The oil reservoir a' may extend from end to end as shown in Figure 1 or may
be divided into two reservoirs as shown in Figure 2.
For closing the oil reservoir and enabling it to be filled I use in some cases a ball
valvefkept normally closed by a spring f¹ but which can be easily opened by inserting
the point of a funnel or oil can through the orifice k. In other cases I use a screw
or plug c as in Figure 2 for closing the oil supply hole.
The extreme ends of the oil reservoirs are closed by screw plugs as g.
By the hereinbefore described means constant and uniform lubrication is obtained
over long periods and owing to the absence of external open oil holes the entrance
of dirt and dust is to a great extent prevented.
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. A loose boss roller having an internal oil reservoir a¹ and provided with
ducts m for delivering the lubricant as set forth and shown.
2. The combination of the hollow axle a¹ (provided with a ball valve for
supplying oil to the interior thereof and having ducts m for delivering the oil)
with a loose boss the whole constituting a self-lubricating loose boss roller as set
forth and shown.
3. The herein described improvement in loose boss rollers consisting of the
projecting pin d taking into a cylindrical groove d' communicating with the slot or
groove d² as and for the purpose set forth.
4. In a roller without a loose boss the herein described internal oil reservoir
having ducts leading therefrom for the purpose of supplying oil to the bearing
surfaces as set forth and shown.
