Improvements in Roller Bearings.
I, EDWARD JONES, of Kynoch Limited, Lion Works, Witton, in the County
of Warwick, Engineer, do hereby declare the nature of this invention to be as
follows.-
-
This invention consists of improvements in roller bearings for shafting and for
like purposes, my object being to so construct and arrange such bearings as to
enable the shaft or journal to be revolved with but a minimum frictional loss
and to permit of the ready and convenient mounting of the same for running
or of its detachment from the bearings when required
In the application of my invention to the construction and aliangement of a
roller bearing suitable for ordinary line shafting, I employ a 1oller frame or
cage consisting of a pair of two pait 1ings forming the end pieces, with distance
rods or pins between them, the ends of such rods being pivotted or otherwise
secured to the 1ngs after the intermediate or distance rollers, hereinafter
described have been placed in position on the iods The parts of each ing
are so scarfed or arranged that when placed in position in the body of the bear-
ing they will hold together and be thus prevented from relative movement.
Upon the distance iods between the ing like end pieces of the frame or cage
I place tubular rollers, preferably employing a number of short lengths of
tube on each rod rather than one length corresponding with the distance
between the end pieces The external diameter of such 1olleis 18 less than the
depth or thickness of the metal in the rings or end pieces, and as the 1ods are
arranged between the inner and outer edges of the rings the rollers do not touch
either the shaft which is embraced by the rings on the body of the bearing
supporting the shaft I sometimes use the rods only without the small 1ollers
The intermediate rollers with the distance rods on which they are mounted
are so pitched as to permit of the insertion between the rolleis or 1ods of other
tubular rollers having a diameter greater than the depth or thickness of the
metal in the ings or end pieces The larger rolleis, which ale preferably
arranged in short lengths as with the smaller and intermediate rolleis herein-
before described, touch both the shaft and the body of the bearing and transmit
the pressure from one to the other As the shaft revolves both the laige and
small rollers are caused to 10tate about their longitudinal axes whilst the com-
plete frame or cage with the whole of the contained rollers is caused to revolve
in the body of the bearing, by arranging the larger and smaller 1olleis alter-
mately and in the manner described, such revolution 18 effected with but a
minimum frictional loss.
I preferably form both the larger and smaller rollers from weldless steel tube
cut into the required short lengths the internal diameter of the small tubes
being such as to permit of their free rotation upon the distance rods or pins
In mounting a shaft for running on my improved bearings I first place one
half of the cage in position with the large or main rollers between the smaller
or intermediate rollers or rods The shaft being lowered on to such half of the

page_text: cage the upper half is placed in position upon the shaft and the main rollers
inserted herein. The upper portion of the cage is secured by the cap or detach-
able portion of the body of the bearing

Improvements in Roller Bearings.
I, EDWARD JONES, of Kynoch Limited, Lion Works, Witton, in the County
of Warwick, Engineer, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement.-
This invention consists of improvements in roller bearings for shafting and for
like purposes, my object being to so construct and arrange such bearings as to
enable the shaft or journal to be revolved with but a minimum frictional loss.
and to permit of the ready and convenient mounting of the shaft or journal fol
running or for its detachment from the bearings when required
In the three accompanying sheets of explanatory drawings to be hereinafter
referred to..
Figure 1 is an end elevation, with one half in section, and Figure 2 a plan of
a plummer block with a swivelling roller bearing constructed and arranged in
accordance with my invention

The same reference letters in the different views indicate the same parts
In the application of my invention to the construction and arrangement of
a roller bearing suitable for ordinary line shafting, I emplov a roller frame or
cage consisting of a pair of two part rings as A A¹ forming the end pieces,
with distance 1ods or pins as B between them, the ends of such rods being
rivetted or otherwise secured to the rings A. A¹ after the intermediate or other
rollers, hereinafter described, have been placed in position on the 1ods
parts of each ing are so scarfed or arranged that when placed in position in
the body of the bearing they will hold together and be thus prevented from
relative movement. Figures 4 and 5 show the two parts of each ring held
by dowel pins or studs as a' but I sometimes scarf the two parts together as
shown at Figures 6 and 7.
The

page_text: Upon the distance rods B between the ring like end pieces A A¹ of the frame
or cage, I place tubular rollers as C (Figure 1) preferably employing a number
of short lengths of tube on each rod rather than one length corresponding with
the distance between the end pieces. The external diameter of such rollers is
less than the depth or thickness of the metal in the rings or end pieces, and
they do not touch either the shaft D which is embraced by the rings or the
body E of the bearing supporting the shaft I sometimes use the rods only
without the small rollers, as shown at Figure 8
The distance rods B are so pitched as to permit of the insertion between the
rods, or the rollers mounted thereon, of other tubular rollers as F having a
diameter slightly greater than the depth or thickness of the metal in the rings or
end pieces A A. The said larger or main rollers F, which are preferably
arranged in short lengths as with the smaller and intermediate rollers herein-
before described, touch both the shaft and the body of the bearing and transmit
the pressure from one to the other As the shaft revolves both the large and
small rollers are caused to rotate about their longitudinal axes whilst the com-
plete frame or cage with the whole of the contained rollers 18 caused to revolve
in the body of the bearing, by arranging the larger and smaller rollers alter-
nately and in the manner described, their meeting surfaces are caused to 1oll
together as 18 clearly indicated by the diagram at Figure 10, and thus the revo-
lution of the shaft 19 effected with but a minimum frictional loss at its bearings
I preferably form both the larger and smaller rollers from weldless steel tube
cut into the required short lengths the internal diameter of the small tubes
being such as to permit of their free rotation upon the distance 1ods or pins
Such hollow rollers very slightly yield or flatten under the pressure imposed
upon them at their points of contract, but as the metal returns or springs back
to its original form as it moves out of contact, no permanent set or change of
form is imposed upon the rollers The said yielding or spring of the rolleis in
addition to providing an increase of the bearing su face enables the shaft to be
run quietly and steadily at high speeds or under heavy pressures
In mounting a shaft for running on my unpioved bearings I first place one
half of the cage in position in the lower part of the bearing body E, supported
by the plummer block, the said half cage having the larger or main rollers dis-
posed between the smaller or intermediate olleis o rods, as herembefore
described. After the shaft has been lowered on to such half of the cage the
upper half is placed in position upon the shaft, the main rollers of the said
upper half are then inserted therein The upper portion of the body E of the
bearing which 18 finally placed in position over the upper portion of the cage,
is retained by, but is free to move witlun, the plummer block
I sometimes mount the main rollers upon the distance rods of the frame or
cage and dispense with the intermediate rollers, as illustrated at Figure 11, the
internal diameter of the rollers being made slightly larger than the diameter of
the rods on which they are mounted, and the said rods being so pitched that the
rollers shall not touch each other.
For the purpose of locking and securing together the upper and lower parts
of the body E of the bearing to prevent end movement of the one part relatively
to the other, I cut or form a circular groove at the juncture of the two parts for
the reception of a plate as secured in position by a screw as e¹. The bearings
are lubricated through apertures at e² and in the upper part of the body or
casing E
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what I
claim 19-
1 In roller bearings, the combination with the shaft or journal to be sup-
ported of tubular rollers arranged in a frame or cage substantially as described
and as illustrated.
