Improvements in and connected with Ball Bearings.
Year: 1898

page_text: I, EDWARD SMITH HIGGINS, of 33, Comyn Road, Wandsworth Common, Engineer,
do hereby declare the nature of this invention to be as follows:-
This invention relates to the construction of ball bearings and connected parts,
the invention being particularly applicable for the chain wheels of mortising
machines, cycles, or for similar purposes.
According to this invention the external face of the wheel ring is given the
desired formation for the purpose for which it is to be employed, while the interior
of the ring is adapted to form the outer face of the ball race. Loosely fitting
within one side of the opening in the wheel ring is a disc having inclined inner
faces and a central projection or boss adapted to carry the shaft or pin, and on
the opposite side of said wheel ring is a second disc or ring with inclined inner
faces and a central hole adapted to fit upon the boss of the disc first described,
the inclined faces of the two discs forming when in position the inner ball race.
The two discs when placed together have preferably a slightly greater width
than the width of the wheel ring so that such discs may be tightly held together
between brackets or other parts which will in no way bind upon the wheel ring.
The two discs are provided with inner contacting faces so that no undue pressure
may be exerted on the balls.
Dated this 18th of August 1890.

Improvements in and connected with Ball Bearings.
I, EDWARD SMITH HIGGINS, of 33, Comyn Road, Wandsworth Common, Engineer,
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 follow-
ing statement--
This invention relates to the construction of ball bearings and connected parts,
the invention being particularly applicable for the chain wheels of chain mortising
machines, and like wheels where an outer ring runs freely on an inner part.
In order that the invention may be clearly understood reference is made to
the accompanying drawings in which the invention is shown when applied to

page_text: a grooved wheel ring such as is frequently employed for carrying the cutting
chains of a chain mortising machine but it will be understood that the external
face of such wheel ring may be of any desired configuration so as to form say a
sprocket or other wheel.
In the drawings Fig. 1 is a side elevation, Fig. 2 a cross sectional view on the
line y of Fig. 1, and Fig. 3 a sectional elevation on the line z z of Fig. 2.
According to this invention the external face of the wheel ring a is given the
desired formation for the purpose for which it is to be employed, while the interior
of the ring is adapted to form the outer face of the ball race b. Loosely fitting
within one side of the opening in the wheel ring a is a disc c having inclined
inner faces d and a central projection or boss e adapted to carry the shaft or pin,
and on the opposite side of said wheel ring is a second disc or ring with inclined
inner faces and a central hole adapted to fit upon the boss e of the disc c, the
inclined faces dg of the two dises forming when in position the inner ball race.
The two discs when placed together have preferably a slightly greater width than
the width of the wheel ring a as more clearly seen in Fig. 2 so that such discs may
be tightly held together between brackets or other parts which will in no way
bind upon the wheel ring. The two discs are provided with inner contacting
faces so that no undue pressure may be exerted on the balls ; no matter how
closely the discs c and f may be pressed or screwed together.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what I
claim is:-
1. The improvements in ball bearings consisting of the combination of an
outer wheel ring the inner face of which forms the outer portion of the ball race
with inner discs fitting within said wheel ring and provided with inclined faces
which form the inner side of the ball race and balls within said race one of the
said discs being provided with a boss or hub and the other with a hole or recess
adapted to fit upon said boss or hub and contacting faces between said discs to
prevent undue pressure upon the balls, substantially as set forth.
2. The improvements in ball bearings consisting of the combination of an outer
wheel ring the inner face of which forms the outer portion of the ball race with
inner discs fitting within said wheel ring and provided with inclined faces which
form the inner side of the ball race and balls within said race one of the said discs.
being provided with a boss or hub and the other with a hole or recess adapted to
fit upon said boss or hub and contacting faces between said discs to prevent undue
pressure upon the balls, and to cause the outer faces of said discs to extend slightly
beyond the plane of the outer wheel ring substantially as set forth.
