Improvements in Roller Bearings.
We, THOMAS COOPER, of King's Lynn, in the County of Norfolk, Mechanical
Engineer, and WILLIAM HUGH WOODCOCK, of 25, Auckland Hill, West Norwood,
in the County of Surrey, Civil 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 following statement:-
Our invention relates to improvements in roller bearings for axles, shafting
and the like, and has for its object to prevent the rollers dropping out of the
cages or cradles, employed in such bearings for spacing or separating and guiding
said rollers, when the shaft, axle or journal is removed or when the outer casing
is removed from the bearing as the case may be.
The way in which we carry out our invention is as follows;-reference being
made to the accompanying drawings in which Figures 1 and 2 are part longi-
tudinal and cross sections respectively of a bearing comprising our improvements
applied to a case in which the axle, journal or shaft is required to be removed;
Figures 3 and 4 being similar views showing our invention as applied where the
outer casing of the bearing is required to be removed.
The same letters refer to the same or equivalent parts in the different figures.
Referring to Figures 1 and 2, on the ends discs or rings a of the cradle or
cage, which discs or rings are preferably formed solid with the spokes or bars
of said cage, we provide ribs on the lower side or edge of the inner faces of
said end discs or rings, and we provide the roller c with pips or projections c
one at each end, which bear or rest on said ribs or projections b when the axle,
journal or shaft is removed so that the rollers e will be retained in position in
the cage or cradle notwithstanding the removal of the axle, journal or shaft.
In Figures 3 and 4 the ribs or projections 6 on the inner faces of the end discs or
rings a of the cage or cradle are formed at the top or outer edges of said rings, the
rollers in this case being also provided with pips or end projections c which as
in the case of Figs. 1 and 2 will rest of the ribs b when the outer casing of the
bearing is removed thus retaining the rollers in position between the spokes or
bars of the cage.
We arrange that the diameter of the pips on the rollers e and the dimen-
sions of the ribs on the end discs or rings a of the cage or cradle are such that
when the rollers are in their working position the pips c' on the rollers do not
touch the ribs on the cage or cradle."
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:-
In roller bearings the combination, with the axle, journal or shaft and the
axle box or casing of the bearing-of a cage, cradle or frame having ribs or pro-
jections on the inner faces of the end discs or rings thereof, and rollers running
between and on the spokes or bars of said cage or cradle said rollers having pips
or projections on their ends of auch diameter that when the bearing is in run-

cage, substantially as herein set forth with reference to the accompanying draw-
