page_text: Improvements relating to Ball Bearings.
We, CHARLES RILEY GARRARD and CHARLES GEORGE GARRARD, both of 6,
Oliver Road, Birmingham, Engineers, do hereby declare the nature of this
invention to be as follows:-
This invention consists of improvements relating to ball bearings for line
shafting, dynamos, cycle hubs, crank axles, and for other purposes, our object
being to so construct and arrange such bearings as to prevent abrasion or crushing
of the surfaces on which the balls run, and to permit of universal adjustment in
a very simple and effective manner.
The
In the application of our invention we mount a bush or sleeve upon the shaft,
such sleeve being either secured to the shaft or left free thereon to allow it to
accommodate itself by endwise movement to the shaft and the bearing.
external surface of the bush or sleeve we make to a tapered or conical form corre-
sponding with the tapered or conical bore of the outer case of the bearing. We
make the conical bore of the case sufficiently larger than the conical sleeve to
permit of the interposition of rows of balls between the two parts.
To provide for the adjustment of the balls between the sleeve and the outer
casing we employ a washer or cap at one or both ends of the sleeve arranged to
be locked in the required position within the range of adjustment in any ordinary
manner. We preferably interpose a ring of balls between the inner face of the
adjustment washer or cap and the adjacent end of the outer case.
The outer case has preferably a circular or spherical configuration, and is
mounted within a correspondingly cupped aperture of the standard or supporting
body of the bearing.

described and ascertained in and by the following statement:-
This invention consists of improvements relating to ball bearings for line
shafting, dynamos, cycle hubs, crank axles, and for other purposes, our object
being to so construct and arrange such bearings as to prevent abrasion or crushing
of the surfaces on which the balls run and to permit of universal adjustment in
a very simple and effective manner.
The drawing on the attached sheet represents, in sectional elevation, a ball
bearing constructed and arranged in accordance with our invention for service
with ordinary line shafting or with other journals.
In the application of our invention we mount a bush or sleeve as A upon
the shaft B, such sleeve being preferably of case-hardened metal and either
rigidly secured to the shaft in any convenient manner or caused to rotate with
the same whilst being left free to accommodate itself by endwise movement.
The external surface of the bush or sleeve A we make to a tapered or conical form
corresponding with the tapered or conical bore of the outer case D of the
We
bearing, such case being also preferably formed of case-hardened metal.
make the conical bore of the case I) sufficiently larger than the conical sleeve A
to permit of the interposition of rows of balls as illustrated between the two
parts.
We
To provide for the adjustment of the balls between the sleeve and the outer
casing we employ a screwed cap or nut as E and E' at one or. both ends
of the sleeve arranged to be locked in the required position within the range
of adjustment by the nuts F and F¹ or in any other ordinary manner.
preferably interpose a ring of balls between the inner face of each of the adjust-
ment washers or caps and the adjacent end of the outer case D) as illustrated.
The outer case has preferably a circular or spherical configuration, and is
mounted within a correspondingly cupped aperture of the standard or supporting
body C of the bearing.
By our invention we are readily enabled to produce ball bearings of such a
length and diameter as will carry the load without excessive pressure per ball,
and yet to be universally adjustable.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is :-
1. In ball bearings for line shafting and for other purposes, the use of a
bush or sleeve rotating with the shaft or journal on which it is mounted and
having rows of balls interposed between its external surface and the internal
surface of an outer casing, substantially as described.
2. In ball bearings for line shafting and for other purposes, the combination with
a bush or sleeve as claimed in the preceding claim, of a screwed adjustment cap
or nut on one or both ends of the said bush or sleeve, substantially as described.
3. Ball bearings for line shafting and for other purposes constructed and
arranged substantially as described and as illustrated.
