Improvements relating to Roller Bearings.
We, MOSSBERG ROLLER BEARINGS, LIMITED, of 6, Victoria Street, Westminster,
S.W., Manufacturers, (a communication from, Franklin Orris Andrews, of Rock-
land Maine, United States of America), do hereby declare the nature of this
invention to be as follows:-
This invention relates to roller bearings, and has for its object to simply and
effectively secure the bush upon which the rollers or balls rotate on a shaft in
any such position as may be required.
The invention consists in providing for one form of bearing a sleeve with a
tapered exterior corresponding to a tapered interior upon the bush of which
the rollers or balls rotate, the sleeve being preferably provided with axial slits
so as to enable it to be bound tightly upon the shaft on the bush being forced
thereupon by such means as a nut for the purpose.
In carrying the invention into effect in its application to bearings for a shaft
hanger we provide a bracket centrally formed with a hole through which the
shaft or spindle passes, the bracket having recesses at each end in which the
roller cage and rollers and the respective bushes are mounted. "Sleeves are
introduced from each end and their rear opposite edges abut against a thrust
ring. Each of the sleeves is provided with axial slits to permit of its being
compressed so as to be bound upon the shaft and each has its exterior tapered.
A hardened steel bush is provided having its interior tapered of a taper corre-
sponding to the exterior taper upon the sleeves and such bush is fitted upon cach
of the sleeves, and a nut is provided to screw upon the screw threaded extremity
of the sleeve
the
SO as to force the bush home and thereby bind
sleeve upon the shaft. Hardened steel bushes are fitted upon each end
of the bracket to form the exterior bearing surface and between the two bushes
thus mounted the roller cage provided axially with rollers is inserted and
retained in position by means of a cap or plate. By this arrangement the
bracket may be secured to the shaft or spindle in any desired position and the
use of keyways in the shaft or spindle and keys are obviated.
When applying our improvements to a long bearing we mount one or more
roller cages upon bushes placed upon the shaft or axle and we sometimes make
the outer faces of such bushes with conical recesses or beds into which like
tapered or conically ended tubular distance pieces may engage. One abutment
end for the distance pieces we form upon the inner shoulder or collar of the
journal upon the axle or shaft while the other abutment we form upon an
adjustably sliding collar carried upon the recessed end of the shaft so that
when a locking nut or the like is screwed up or adjusted the distance pieces may
be firmly pressed against the roller cage bush or bushes which is or are thereby
secured in the desired position upon the revolving shaft or journal.
When arranging a series of such roller rings or cages upon bushes kept apart
by distance pieces having conically bearing ends, we find it advantageous to

page_text: introduce metal or other suitable material keeps between the bushes and the
ends of the bearing or axle box so as to prevent too great a lateral movement
of the rollers and their cages.
We do not limit the application of our invention to any special form of
bearing or axle box and we modify the methods of securing the adjustment of
the bush or bushes to suit the type and form of bearing or axle box to which
the improvements are to be adapted.

Improvements relating to Roller Bearings.
'We, MOSSBERG ROLLER BEARINGS, LIMITED, of 6, Victoria Street, Westminster,
S.W., Manufacturers, (a communication from Franklin Orris Andrews, of Rock-
land Maine, United States of America), 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:-
1
This invention relates to roller bearings and has for its object to simply and
effectively secure the bush upon which the rollers or balls rotate on a shaft in
any such position as may be required.
The invention consists in providing for one form of bearing a sleeve with a
tapered exterior corresponding to a tapered interior upon the bush on which the
rollers or balls rotate, the sleeve being preferably provided with axial slits
so as to enable it to be bound tightly upon the shaft on the bush being forced
thereupon by such means as a nut for the purpose.
In the accompanying sheet of explanatory drawings;
Figure 1 is a sectional elevation of our improved bearing, and Figure 2 is an
end elevation of the same one half of such being shown in section.
In carrying the invention into effect in its application to bearings for a shaft
hanger we provide a bracket or carrier A centrally formed with a hole, through
which the shaft or spindle B passes, the bracket having recesses C at each end
in which the roller cage 1) and rollers E and the respective bushes are mounted.
We introduce a sleeve F from each end and cause their rear opposite edges f to
abut against a thrust ring G. Each of the sleeves F is provided with axial slits
or formed with other openings in the surface to permit of its being compressed
so as to be bound upon the shaft and each has its exterior tapered. A hardened
steel bush H is provided having its interior formed of a taper corresponding to
the exterior taper upon the sleeves F and such bush is fitted upon each of the
sleeves, and a nut J is provided to screw upon the screw threaded extremity of
the sleeve so as to force the bush home and thereby bind the sleeve upon the
shaft. Hardened steel bushes K are fitted upon each end of the bracket to
form the exterior bearing surface for the rollers and between the two bushes K
and H thus mounted the roller cage D provided axially with rollers E is inserted
and retained in position by means of a cap or plate. By this arrangement the
carrier boss or bracket A may be secured to the shaft or spindle B in any
position and the use of keyways in the shaft or spindle and keys is obviated.
When applying our improvements to a long bearing we mount one or more
roller cages upon bushes placed upon the shaft or axle and we sometimes make

page_text: the outer faces of such bushes with conical recesses or beds into which like
tapered or conically ended tubular distance pieces may engage. One abutment
end for the distance pieces we form upon the inner shoulder or collar of the
journal upon the axle or shaft while the other abutment we form upon an adjust-
ably sliding collar carried upon the recessed end of the shaft so that when a
locking nut or the like is screwed up or adjusted the distance pieces may be
firmly pressed against the roller cage bush or bushes which is or are thereby
secured in the desired position upon the revolving shaft or journal.
When arranging a series of such roller rings or cages upon bushes kept apart
by distance pieces having conically bearing ends, we find it advantageous to
introduce metal or other suitable material keeps between the bushes and the
ends of the bearing or axle box so as to prevent too great a lateral movement of
the rollers and their cages.
We do not limit the application of our invention to any special form of
bearing or axle box and we modify the methods of securing the adjustment of
the bush or bushes to suit the type and form of bearing or axle box to which
the improvements are to be adapted.
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 a roller bearing or shaft carrier the arrangement of a sleeve or bush
having its outer surface tapered and provided with openings or yielding passages
therein and having a tightening nut attached upon its end for keeping it in
position upon a shaft and also for securing upon its tapered outer surface a
bush upon which the rollers revolve substantially as herein before described and
as illustrated in the accompanying drawings.
2. In a roller bearing the combination of a loose contracting shaft sleeve
with a bush fitting thereon for carrying a cage or ring of rollers, and having a
thrust ring or rings placed within the recess into which such combined sleeve
and bush is inserted substantially as hereinbefore described and as illustrated in
the accompanying drawings.
