COMPLETE SPECIFICATION.
Composite Washer for the Prevention of Friction in Mechanism, and
for similar purposes.
We, WILLIAM WOODALL, THOMAS WILLIAM WOODALL, HARRY LEE
WOODALL, and GEORGE JAMES WOODALL, all of 33 Newton Street, Piccadilly,
Manchester, in the County of Lancaster, trading as The Patent Washer Company,
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 washers such as are interposed in mechanism between
one part which is moveable and an adjoining part which is stationary in order to
prevent friction, and for similar purposes. Said washers have hitherto been
formed of leather and the object of this our invention is to effect economy in
washers that may be employed as hereinbefore named. We effect this object by
the means hereinafter described and as shown in the accompanying sheet of
drawings in which
Fig. 1 represents a front view and Fig. 2 a sectional edge view of a leather
washer such as is now used:
Fig. 3 is a front view, and Figs. 4 and 5 are sectional edge views of a washer
according to this invention.
We construct washers of any size, shape and thickness that may be required for
the purposes herein before named, by a combination with a backing of thin leather
as a Fig. 4 or other suitable material such as canvas or like fabric, of a composition
consisting of ground cork 12 parts, oil 3 parts, red lead part, yellow ochre 1 part
and resin part, or in such proportions that when mixed and laid on or spread
over said leather or other backing said composition will form a firm but flexible
substance as that is equal in resistance to the washers which are made wholly of
leather as at present used. The aforesaid washers may also if required be faced
with leather as d Fig. 5. By these means we obtain a washer that is equal to
leather in durability at a greatly reduced cost, and said washers may be employed
in all places where friction is produced by rubbing surfaces. Holes as may be
formed in said washers if required as when employed on the axles of carriages and
like vehicles.
Having now particularly described and ascertained the nature of this our said
invention and in what manner the same is to be performed we declare that what
we claim is :-
1st. Composite washers that are formed of a composition consisting of cork, oil,
red lead, yellow ochre and resin in combination with a backing of leather or other
suitable material such as canvas or like fabric, and interposed in mechanism
between one part which is moveable and an adjoining part which is stationary, and
for similar purposes substantially as herein before described.
2nd. Composite washers that are formed of a composition consisting of cork,
oil, red lead, yellow ochre, and resin in combination with a backing of leather or
other suitable material such as canvas or like fabric for use on the axles of
carriages and other vehicles substantially as and for the purpose herein before
described.
