Improvements in or connected with Axle Boxes.
I, ALBERT WEICKMANN, of 17 II Bogenhausen, Munich, in the Empire
of Germany, Engineer, do hereby declare the nature of this invention to be
as follows:-
This invention relates to an axle box for a roller bearing which is mainly
intended to be employed for heavy vehicles such as locomotives, railway wagons
and the like. In the axle boxes at present employed owing to the sliding move-
ment of the axle in the cheeks of the bearings a not inconsiderable power is
necessary for overcoming the frictional resistance which it is endeavoured by
the free use of lubricant to partially reduce. This frictional resistance, which
naturally also increases with the increasing weight of the load to be carried,
is so considerable in the case of heavy loads such as that of a locomotive, that
the quantity of lubricant necessary forms a not inconsiderable part of the work-
ing expenses.
In order to reduce the frictional resistance and thereby the consumption of
lubricant as well as to convert the sliding movement of the axle into a roller one
by the use of balls and rollers, it is sought thereby to form a roller bearing.
Such roller bearings have indeed already been constructed by others but hitherto
difficulties have been found in retaining the rollers in the bearings in a simple
manner and in preventing the axles from being displaced in the bearings through
lateral shocks.
The roller bearing hereinafter described attains this object by means of pro-
jecting rings or shoulders.
The axle is revolubly mounted on a suitable number of cylinders or rollers in
the body of the bearing and in the cover of the bearing. By turning out the two
parts of the bearing to receive the rollers and by shaping the parts of the bearing
to suit the projections of the journals, annular projections shoulders or rings are
formed which have for their object to receive lateral shocks. The lateral shocks
and pressures are here received by the bearing itself so that the rollers are entirely
relieved as regards same. The two parts, body and cover of the bearing are firmly
connected with one another by a frame formed of clamps and bolts with the
assistance of nuts, whilst the clamps resting in a recess of the two parts of the
bearing form at the same time slide surfaces for the axle fork, which latter is
fastened by means of rivets to the frame construction of the locomotive or the like.
The lubrication of the roller bearing takes place by means of a lubricator and
the cleaning of the same is also effected by the same, by petroleum being poured

page_text: in at the top and allowed after several revolutions of the axle to flow away at a
discharge orifice after a screw has been unfastened therein, the screw being again
tightened when the bearing is sufficiently clean.

I, ALBERT WEICKMANN, of 17 II Bogenhausen, Munich, in the Empire
of Germany, 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 relates to an axle box for a roller bearing which is mainly
intended to be employed for heavy vehicles such as locomotives, railway wagons
and the like. In the axle boxes at present employed owing to the sliding move-
ment of the axle in the cheeks of the bearings a not inconsiderable power is
necessary for overcoming the frictional resistance which it is endeavoured by
the free use of lubricant to partially reduce. This frictional resistance, which
naturally also increases with the increasing weight of the load to be carried,
is so considerable in the case of heavy loads such as that of a locomotive, that
the quantity of lubricant necessary forms a not inconsiderable part of the work-
ing expenses.
In order to reduce the frictional resistance and thereby the consumption of
lubricant as well as to convert the sliding movement of the axle into a rolling
one by the use of balls and rollers, it is sought thereby to form a roller bearing.
Such roller bearings have indeed already been constructed by others but hitherto
difficulties have been found in retaining the rollers in the bearings in a simple
manner and in preventing the axles from being displaced in the bearings through
lateral shocks.
The roller bearing hereinafter described attains this object by means of project-
ing rings or shoulders.
In the accompanying drawings,
Figures 1 and 3 are vertical, and Figure 2 a horizontal section of this improved
bearing.
The axle is revolubly mounted on a suitable number of cylinders or rollers c
in the body of the bearing and in the cover a of the bearing. By turning out
the two parts of the bearing to receive the rollers and by shaping the parts of the
bearing to suit the projections of the journals, annular projections, shoulders or
rings are formed which have for their object to receive lateral shocks. The
lateral shocks and pressures are here received by the bearing itself so that the
rollers are entirely relieved as regards same. The two parts, body and cover of
the bearing are firmly connected with one another by a frame formed of clamps
and bolts with the assistance of nuts m, whilst the clamps d d resting in a recess
of the two parts of the bearing form at the same time slide surfaces for the axle
fork e, which latter is fastened by means of rivets to the frame construction i of the
locomotive or the like.

The lubrication of the roller bearing takes place by means of a lubricator f
Figure 3, and the cleaning of the same is also effected by the same, by petroleum
being poured in at the top at f and allowed after several revolutions of the axle h

the screw being again tightened when the bearing is sufficiently clean.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:-
1. A roller-bearing axle-box for axles and shafts of all kinds characterised by
rings or shoulders (c) provided on the bearings and adapted to hold the rollers
and to also absorb lateral pressures and shocks acting axially on the shaft, sub-
stantially as herein before described.
2. In a roller-bearing axle-box such as described the application and use of a
frame formed by clamps (dd) and bolts (n) for connecting the body and cover
of the bearing and for preventing the mutual displacement or adjustment of the
lower as against the upper bearing, said clamps (d d¹) forming simultaneously
slide surfaces for the axle forks or jaws or the like constructive parts, substantially
as herein before described.
Deted this fith day of July 1898.
