Improvements in Roller Bearings.
We, GEORGE DANIELS, Fitter, and GEORGE GUNNELL, Tinsmith, both of 20,
Compton Road, Wyld's Lane, Worcester, 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 for improvements in roller bearings has for its object an im-
proved arrangement whereby the friction is still further reduced and the rollers
are caused to wear evenly; and consists essentially in arranging the rollers so
that they do not all bear upon the same portion of the shaft thus ensuring that all
portions of the shaft bear upon one or other set of rollers.
In order that this invention may be more clearly understood, reference is had
to the accompanying sheet of illustrative drawings on which
Fig. 1 is an elevation showing a roller bearing constructed according to this
invention the axle box or bearing not being shown and
Fig. 2 is a cross sectional view of the same on the line A B, Fig. 1.
The cage A for supporting the rollers is adapted to be fitted into the axle box
or bearing in a manner well understood. The cage A is provided with the end
plates a al between which the spindles B are supported. The spindles B are
attached at one end to the end plate a and their other ends are formed with square
portions b and pass through the other plate a¹. Nuts 6' secure them together and
the square portions 6 prevent the spindles from turning. The rollers C C¹ are
mounted on these spindles B and support the shaft or axle D between them.
These rollers CC of which there are several, (in this case three) on each spindle
are arranged so that they do not all bear on the same portions of the shaft or
axle D. Thus the rollers C are nearer together than the rollers C¹. Sleeves c on
the same spindles as the rollers C make up the necessary width and retain the
rollers C in their proper positions.
It will therefore be seen that the shaft or axle D is supported for the whole of
the width of the cage A while all the rollers do not bear on the same portions
thus causing the rollers to wear more evenly, and lessening the friction on the
shaft or axle D. The bearing can, moreover, be readily got at and taken to
also be varied.
pieces when required. The arrangement of the rollers can
Although only two different arrangements of the rollers are shown on the draw-
ings it will be readily understood that there may be three or more different
arrangements if desired.
Roller bearings constructed according to this invention can be used in axle
boxes for railway and tramway and other vehicles also for supporting shafting
generally and for other purposes for which roller bearings can be applied.
When applied for shafting the end plates a a¹ are made in halves secured

page_text: Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is:-
-
(1) An improved roller bearing having sets of rollers mounted on spindles
around the shaft or axle to be supported, the sets of rollers being so arranged
that they do not all bear on the same portions of the said shaft or axle, sub-
stantially as described, and for the purposes specified.
(2) An improved roller bearing comprising the cage A supporting the
spindles B, rollers CC mounted on the said spindles in such manner that they
do not all bear on the same portions of the shaft or axle D, and sleeves c on the
same spindles as the rollers C to make up the necessary width and retain them
in their proper positions, substantially as described with reference to the accom-
panying drawings and for the purposes specified.
