PROVISIONAL SPECIFICATION.
Improvements in Lubricating Washers for Cap Spinning and
Twisting Frames.
I, CHARLES BRIGG, of Evergreen Cottage, Manchester Road, Bradford, in the
County of York, Washer Manufacturer, do hereby declare the nature of this
invention to be as follows:-
This invention relates to improvements in lubricating washers used in cap
spinning and twisting machinery for separating the wharles from the lifter plate
and particularly to the washer for which Letters Patent were granted to me on
the 7th day of January 1884 numbered 893 and the object of the invention is to
enable the central portion of the washer to be removed or replaced when it
becomes reduced. or worn away by the action of the wharle without the necessity
of replacing the whole of the washer.
For this purpose I employ a metal shell having a recess underneath for the wad
and an annular perforated recess in the top face and also a projecting claw on the
periphery to engage the edge of the lifter plate to prevent the washer rotating.
An opening of circular or other suitable form is made in the centre of the shell
adapted to receive a box wood, anti-friction metal, composition fibre, or other
suitable plúg the upper face of which forms the bearing for the wharle. In order
to retain this plug in position the central. opening in the shell is provided with a
raised rim cut or broken at suitable intervals so as to leave the rim more or less
springy or pliable and enable it to grip the plug which is forced into position.
The shell may be made of thin sheet metal stamped or pressed to form and
having an inner piece fitted therein. to receive the wad provided with holes or
perforations corresponding to the perforations in the annular recess of the shell.
The.claw for engaging the side of the lifter plate may be formed upon this inner
piece and project through an opening in the periphery of the shell. And to retain
the inner piece in position spring or clip pieces may be cut in the periphery of the
shell-to engage the. inner piece or to engage dovetail or under-cut projections
thereon.

Improvements in Lubricating Washers for Cap Spinning and
Twisting Frames.
1, CHARLES BRIGG, of Evergreen Cottage, Manchester Road, Bradford, in the
County of York, Washer Manufacturer, 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 :-
This invention relates to improvements "in lubricating washers used-in- cap
spinning and twisting machinery for separating the wharles from the lifter plate
aud, particularly to the washer. for which Letters Patent were granted to me on
the 7th day of January 1884 numbered 893 and the object of the invention is to
enable the central portion of the washer to be removed or replaced, when it becomes

reduced or worn away by the action of the wharle, without the necessity of
replacing the whole of the washer.
Reference is to be had to the accompanying sheet of drawings forming a part of
this Specification, in which similan letters of reference indicate corresponding
parts in each of the figures.
Eigure 1, represents an elevation of the lower end of a spindle of a cap 'spinning
machine with a cross section of the lifter plate, and a diametrical section of my
improved washer with the wharlé in position thereon.
Figure 2; is a separate elevation of the washer.
Figure 3, is a diametrical section of the same and
Figure 4, is a plan view of the same without the renewable portion shown in the
next figure.
Figure 5, is a separate view of the removable central portion of the washer.
Figures 6 to 12 illustrate a similar-washer-constructed-in-a-somewhat different
manner.
In Figure 1, the lifter plate A, the spindle B and the wharle and tube C are of
the ordinary form and a recess D is formed in the lifter plate to receive a
lubricating wad in the ordinary way. The shell E or outer portion of the washer
formed of metal, but similar to that shown in the above cited Letters Patent, is
provided with a recess F beneath to receive a lubricating wad, a hook G to engage
the back of the lifter plate to prevent the washer rotating and an annular recess H
at the top to receive the lubricant and having inclined radial ducts J
communicating with the recess F.
A concentric opening K is formed through the shell E having radial
projections L formed thereon and three or more claw pieces M upon the upper
edge. The renewable centre N of anti-friction metal, compressed fibre or
imitation leather commonly called_composition. fibre, box-wood, or other suitable
substance is placed in the opening K and is supported by the radial projections L.
The claws M are then pressed or bent inward so as to clasp the centre N and
retain it in position.
In the modified construction shown in Figures 6 to 12 the shell is formed in
two pieces an outer portion E¹ stamped from thin sheet metal and an inner
portion E which may be made of malleable cast iron.
Figure 6, illustrates a diametrical section of this arrangement. Figure 7, is a
separate plan view of the outer portion E and Figure 8, is a diametrical section
of the same. Figures 9 and 10 are respectively a plan and cross section of the
inner portion E³. Figures 11, and 12 are a sectional view and a plan view of the
renewable centre.
The hook G is formed on E² and is passed through an opening O made in the
side of E' and to hold the portion E tightly in position within the portion El
dovetail shaped or undercut pieces P are formed upon the periphery of E³ to engage
the spring clips R cut in the sides of E'.
The central opening K in the shell E' may be made D shaped or of polygonal
section and the renewable centre made of a similar form, to fit so as to prevent it
rotating. The sides M of the opening K are preferably formed with slits S so as
to make them more or less springy and tightly hold or clasp the renewable
centre..
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the samé is to be performed, I declare that what I
claim is :
1. A lubricating washer for the spindles of a cap spinning and twisting machine,
having a replacable or renewable central bearing for the 'wharle, substantially as
hereip shown and described.
2. A. lubricating washer-for the spindles of cap spinning and twisting machines,
in which the permanent portion is enclosed within a thin sheet metal-shell, sub-
stantially as herein shown and described.
:

page_text: 3. A lubricating washer having a renewable central bearing of circular,
polygonal or other suitable shape retained in position by spring pieces or clips
forming the side of a concentric opening in the permanent portion of the washer,
substantially as herein shown and described.
