COMPLETE SPECIFICATION.
A Loose Ball Bearing Nest for Axles, Shafts, Spindles, and like
Rotating Objects.
I, ROBERT FREDERICK HALL, of Sherlock Street, in the City of Birmingham,
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 a loose nest or carrier for holding the ball bearings of
spindles, shafts, axles and other rotating bodies and consists in the employment of
a ring whose inside periphery, which constitutes the ball race, is fitted with cage
plates provided with part ball races on their inner sides and which both confine the
balls and form part races within which they run.
Such rings, nests or carriers are supplied to engineers, manufacturers and others
as an article of commerce in standard sizes. Engineers or manufacturers can bore
out any part of a machine requiring to be provided with ball bearings and fit the
said loose ring or nest of balls therein by any suitable means.
Figure 1 of the accompanying drawing represents a front elevation of a loose
nest of balls or ball bearing holder constructed according to my invention.
Figure 2 is a longitudinal vertical section and Figure 3 is a cross section of the
component parts of the nest separated.
Figure 4 is an inside view of one of the cage plates, showing the part ball race
formed on its side, adjacent to the inner periphery.
Figure 5 represents a cross section of the said nest applied to a machine and with
the spindle of a pulley passing through it.
The same letters of reference indicate corresponding parts in the several figures
of the drawing.
a is a ring or circular frame, interiorly fitted with opposite cage plates b,
separated from one another by a space about equal to the diameter of the ball
bearings c, and having upon their inner sides 6', immediately adjacent to the inner
periphery 62, a part ball race 3, (which prevent the balls from falling out of
place by contracting the distance between the inner edges of the plates) whilst the
distance between the inner and outer peripheries 3, 4, of the said cage plates
being slightly less than the height of the balls c, enclosed between them, and when
the said part ball race or cage plates b, are in position, an annular space or gap bo,
is left through which the contacts c', of the balls extend and upon which the
spindle d, or like rotating part revolves, although if required, the spindle may be
stationary and the nest may be rotated around it.
Where great weight is to be sustained, and one row of balls is insufficient, any
number of rings or nests of balls can be used side by side and where width and
rigidity of bearing is required, two such rings separated by a distance piece, may
be used.
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 ball bearing nest, consisting of a circular frame or carrier. having located

page_text: within it, a series of ball bearings confined by cage plates having part ball races or
flanges formed near their inner peripheries, as set forth.
Dated this 21st day of May 1896.
