PROVISIONAL SPECIFICATION.
Improvements in the Means or Method of Lubricating the Spindles,
Wharles, and Tubes of Spinning and Twisting Machinery.
We, JOHN DAWSON and ROBERT SOUTHWORTH DAWSON, both of Bower
Green Shed, Leeds Road, Bradford, in the County of York, Spinners, do hereby
declare the nature of this invention to be as follows:-
This invention relates to improvements in or appertaining to lubricating devices
commonly called lubricating washers for the spindles, wharles and tubes of cap
and other spinning machinery requiring such washers, and its object is to efficiently
lubricate these parts and economise the lubricant.
For this purpose we employ a cup or recessed washer adapted to hold a wad and
be supported by the lifter plate in the ordinary way. The bottom of this cup is
made deeper at the outer edge than close to the spindle or is inclined downwards
from the spindle to the periphery, or a raised lip may be formed around the central
hole for the spindle, or a recess or recesses may be otherwise formed in the bottom
of the cup below the level of the central hole adapted to retain the lubricant which
is fed to the spindle as required by the capillary action of the wad.
The tube, and the wharle may be supported by an annular projection on the
base revolving upon a suitable washer which may rest directly upon the wad. But
to remove the pressure off the wad projections may be formed on the bottom of
the cup to support the said washer or this washer may be provided with arms or
their equivalent arranged to rest upon a shoulder or the like formed on the internal.
periphery of the cup.
To collect the lubricant thrown off by the centrifugal force, and return it to the
wad or the recess below, we employ an externally flanged or a dished cover the
periphery of which fits into the top of the lubricating cup. The top of this cover
lies above the bottom of the said projection on the base of the wharle and a central
hole is made in the cover to allow the said projection to freely pass through. This
central hole may be formed with the flange extending downwards to prevent the.
lubricant rebounding out of the cover. A wad may be placed in the cover.

We, JOHN DAWSON and ROBERT SOUTHWORTH DAWSON, both of Bower

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 improvements in or appertaining to lubricating devices.

page_text: commonly called lubricating washers for the spindles, wharles and tubes of cap and
other spinning machinery requiring such washers, and its object is to efficiently
lubricate these parts and economise the lubricant.
For this purpose we employ a cup or recessed washer adapted to hold a wad and
be supported by the lifter plate in the ordinary, way. The bottom of this cup is
made deeper at the outer edge than close to the spindle or is inclined downwards
from the spindle to the periphery, or a raised lip may be formed around the central
hole for the spindle, or a recess or recesses may be otherwise formed in the bottom
of the cup below the level of the central hole adapted to retain the lubricant which
is fed to the spindle as required by the capillary action of the wad.
The tube and the wharle may be supported by an annular projection on the base
revolving upon a suitable washer which may rest directly upon the wad. But to
remove the pressure off the wad projections may be formed on the bottom of the
cup to support the said washer or this washer may be provided with arms or their
equivalent arranged to rest upon a shoulder or the like formed on the internal
periphery of the cup.
To collect the lubricant thrown off by the centrifugal force, and return it to the
wad or the recess below, we employ an externally flanged or dished cover the
periphery of which fits into the top of the lubricating cup. The top of this cover
lies above the bottom of the said projection on the base of the wharle and a central
hole is made in the cover to allow the said projection to freely pass through. A
wad may be placed in the cover..
Reference is to be had to the accompanying sheet of drawings forming a part of
this Specification, in which similar letters of reference indicate corresponding parts
in each of the figures.
Figure 1, represents an end view of a lifter plate of a spinning frame and a
wharle with a portion of the tube and spindle having our improved lubricator
applied thereto.
Figure 2, is a similar view with the lubricator in section.
Figure 3, represents a plan view of Figure 1 without the wharle and tube.
Figure 4, represents a diametrical section of the said cap or cover.
Figure 5, represents a diametrical section of said cup together with the washer
for supporting the wharle.
Figure 6, is a plan view of the same with a felt wad therein.
Figures 7 and 8 respectively represent a side view and plan view of a conical
ring upon which the wharle revolves.
The lifter plate A, the spindle B, the tube C and the wharle D may be of
ordinary construction excepting that the projection D' on the under side of the
wharle is preferably made a little longer than usual and its lower end D³, passing
through the central hole E in the cap or cover E³, is made larger in diameter than
the part immediately above it therefore when the wharle is in operation centrifugal
force checks any tendency of the lubricant to creep up the projection.
The bottom of the cup F is raised around the central opening F³ for the
spindle B and thus forms an annular recess to receive and hold the lubricant. A
felt wad or wads G are placed in this recess and as the supply of lubricant is
excessive in case the wad touches the spindle all round the hole through the wad
may be heart shaped as shown by the broken lines G and only touch the spindle
at the point G³, Figure 6. The perforated washer or disc H is placed over the
wad G and it is preferably supported by the shoulder F formed around the interior
of the cup. The conical ring J is preferably placed on the centre of the disc H
for the projection D2 to revolve upon and forms a readily renewable bearing.
The cap or cover E is placed over the disc Hand its annular sides pass well
down into the cup and rest upon the said disc. This cap or cover, besides excluding
dust and the like, collects any lubricant that may be thrown off at the base of the
projection D and allows it to gravitate back to the wad. The top of the cap is
preferably dished or inclined towards the centre to facilitate supplying the lubricant
to the cup through the hole E instead of lifting the cap.

page_text: 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 :
1. A lubricator for the spindles of spinning or twisting machinery consisting of
a cup adapted to receive a wad and having a support for the wharle, and a
top of which extends above the bottom of the projection upon which the wharle
the
cap
revolves and the sides of said cap extend down into the said cup, substantially as
herein shown and described.
2. The combination with the cup F' the bottom of which is formed to receive
and hold a supply of lubricant of the cap E' the sides of which fit into the said cup
said cap having a central hole for the projection on the underside of the wharle to
pass into, substantially as herein shown and described and for the purpose
specified.
3. The combination of the cup F2, the cap E' and the washer or disc H, formed
substantially as herein shown and described and illustrated in the accompanying
drawings.
