Improvements in Roller Bearings.
We, MOSSBERG ROLLER BEARINGS LIMITED, of 6, Victoria Street, London, S. W.,
Manufacturers, (a communication from Frank Mossberg, of 101, Sabin Street,
Providence, Rhode Island, United States of America, Manufacturer), do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement;-
-
This invention relates to roller bearings of such design as those described in
the Specification to Letters Patent No. 3414, dated 10th February 1898, granted
to Frank Mossberg, and had for its object to simplify the construction of the
cages employed for holding the rollers and to minimise the cost of production.
The invention consists in the formation of the cage of a roller bearing in such
a manner that the rollers may be introduced into their pockets longitudinally or
endwise and be retained in position by means of a ring that is shrunk, or mounted
upon the peripheral edge of the cage and secured in that position, as hereinafter
described.
The invention is illustrated in the accompanying drawing in which:
Figure 1 represents an axial sectional elevation of a hub fitted with roller
bearings according to the invention while,
Figure 2 represents in side sectional detail elevation the cage employed and
Figure 3 a front elevation corresponding thereto with elevation in section of the
retaining ring employed.
In carrying the invention into effect as illustrated in the accompanying draw-
ings a bearing ring A is shrunk upon the axle B, upon an enlargement 61 or is
otherwise affixed thereto by a key or by a square or other irregular formation of the
axle, and a corresponding bearing ring A is similarly mounted upon the reduced
extremity 62 of the axle. Upon the bearing rings A A¹ the roller cages C C¹ are
respectively mounted so that the peripheral surfaces of the rollers contained
therein which protrude beyond the interior face of the cages lie in contact with and
rotate upon such bearing rings.
The roller cages CC₁ are provided of relatively soft metal such as brass and are
formed with pockets 1) which are milled of such shape that the rollers E may
loosely fit therein and may protrude beyond their interior and exterior peripheries
so as to lie in contact and rotate upon the bearing rings A A' on the interior, and
upon the bearing faces G1 G2 of the sleeve G on the exterior.
The pockets D are open at one end C2 of the cage so that the milling of the
pockets may be conveniently effected but a continuous edge or flange C³ is left
upon which a ring H preferably of steel which may also be hardened is shrunk or
mounted after the series of rollers have been introduced into the pockets, so that
they are thereby retained.
The soft metal of the edge or flange (³ is burred over, spun, hammered or other-
wise forced against the edge of the ring H or into a peripheral rebate provided in
the ring so that the accidental displacement of the ring is entirely prevented.

page_text: The sleeve G is fixed within the timber I of the hub, and after the plate N is
applied to the boss O of the axle and secured in position by means of screws n,
and after the bearing ring A is mounted in position the cage C is applied and
the extremity of the axle introduced within the sleeve G. The bearing ring A¹
with its cage C¹ is mounted upon the extremity 62 of the axle, and the application
of the protecting plate or washer J and finally the nut K completes the adjust-
ment of the bearing, and the dust cap L is applied.
It is obvious that a roller cage such as herein before described may be used for
general purposes, and may be of conical or parallel form.
Having now particularly described and ascertained the nature of our said in-
vention, and in what manner the same is to be performed, we declare that
we claim is: -
1.—In roller bearings the formation of the cage for containing the rollers in
such a manner that the rollers may be introduced endwise and be retained in
position. by means of a ring shrunk or mounted upon the cage and secured sub-
stantially as herein before described and illustrated.
2. In roller bearings a cage for containing the rollers constructed as and for
the purpose hereinbefore described..
