Improvements in and connected with Washers for Bolts, Studs,
Spindles, and the like.
I, WILLIAM EDWIN HEYS of 70 Market Street, Manchester in the County of
Lancaster, Patent Agent, do hereby declare the nature of this invention to be as
follows:-
This invention relates to washers for bolts studs spindles and the like, and
particularly to such washers as are used in machinery and, generally, between a
fixed and a vibrating or rotating surface, its object being to reduce friction and to
prevent motion being conveyed through the washer from one part to another, as
to a nut for example. According to this invention the washer is made in such a
manner that one of its plane surfaces is capable of rotation relatively to the other.
Between these two parts, balls are inserted, so that the moving part rolls upon the
balls and these roll upon the part which is stationary in use. The two parts are
secured together by an annular connection or connections.
Dated this 8th day of November A.D. 1894.

Improvements in and connected with Washers for Bolts, Studs,

1, WILLIAM EDWIN HEYS of 70 Market Street Manchester in the County of
Lancaster, Patent Agent, do hereby declare the nature of this invention, and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement :-
This invention relates to washers for bolts studs spindles and the like, and
particularly to such washers as are used in machinery and, generally, between a
fixed and a vibrating or rotating surface, its objects being to reduce friction and to
prevent motion being conveyed through the washer from one part to another, as
to a nut for example.
According to this invention the washer is made in such a manner that one of its
plane surfaces is capable of rotation relatively to the other. Between these two
parts balls are inserted, so that the moving part rolls upon the balls and these roll
upon the part which is stationary in use. The two parts are secured together by
an annular connection or connections.
In order that this invention may be more readily understood I have hereto
appended a sheet of drawings reference to which is made hereinafter.
Figures 1 and 2 respectively represent au edge elevation and a transverse section
of one form of the improved washer.
Figures 3 and 4 illustrate respectively the same washer in plan and in plan with
one part removed.

page_text: Figure 5 shews in cross section a modified form of washer which is also shewn in
plan with one part partially broken away in Figure 6.
Similar letters of reference are used to indicate similar parts where they occur
in the different figures.
It will be seen on referring to the drawings that a washer constructed according
to this invention consists essentially of two parts A and B between which are
arranged balls C so that the two parts may rotate one upon the other. In the form
illustrated by Figures 1 to 4 a perforated plate D is loosely placed between the
parts A and B and one of the balls C fits loosely within each perforation. The
inner faces of A. and B are suitably recessed for the reception of the balls. Fitting
tightly upon the upper part of B is a collar ring or the like E furnished with a
flange extending over the edge of the part A in such a manner as to hold the two
parts together without interfering with their independent rotation. It will be
noticed that the part A projects beyond the plane of the restraining ring E so as to
ensure that the nut cotter or other device against which it bears does not come into
contact with the part B.
In the washer shewn in Figures 5 and 6 the plate D is dispensed with and the
balls are arranged to fill or nearly fill the grooves in the adjacent faces of the
parts A and B. These two parts are held together by the edge of the part B
being turned over to engage loosely with the part A. If desired however the
collar E shewn in the previous figures may be employed, and, alternatively, the two
parts of the washer illustrated in Figures 1 to 4 may be held together by turning
the edge of one part over the other.
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
A washer consisting of two parallel parts capable of relative rotation and
between which balls are placed, substantially as and for the purpose hereinbefore
described and as illustrated by the accompanying drawings.
