I, JOSEF KORBULY of Arad in the Empire of Austria, Engineer, 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 relates to axle bearings and is an improvement in the bearing
making the object of Letters Patent No 112 dated 2nd Jan. 1894.
In the annexed drawing:
Fig. 1 is a longitudinal vertical section of the improved axle box with leather
washers for, tightening.
Fig. 2 is a transversal section.
Fig. 3 is a transversal section showing the tightening arrangement.
Fig. 4 shows a detail of Fig. 1.
Fig. 5 is a longitudinal vertical section of the improved axle-box, with tightening
leather crowns.
Fig. 6 is a transversal section of the tightening arrangement.
Fig. 7 shows a detail of Fig. 5.
Fig. 8 shows an improved axle-box to be used for axles having no button at
their extremity.
Figs. 9 and 10 show details of the tightening nut.
Figs. 11 and 12 are sketches of the axle-bearings as they are used for any kind
of axle-box.
Figs. 13 and 14 show the same with ring connections. With the axle-boxes
for railway wagons (Patent No 112 of the 2 Jan. 1894) it has been proved that in
practical use the wearing of the axle-bearings is insignificant and consequently,
the faculty of rotation of the bearings is of no importance. Moreover, it has been
proved that through the rapid rotation of the axle, an empty space is produced in
the narrow box, between the axle and the bearing by which the lubrication oil
is sucked through the lubricating holes.
Conformably with these authentications and in order to manufacture axle boxes
more simply and cheaper, we may proceed with the following improvements.
The flanges of the axle box and the sleeve with its annular projection of
Patent No 112 of the 2 Jan. 1894 are done away with, on the contrary in the
improved axle box the casing or axle-box A (Fig. 1) is placed directly on the
parts of the brasses d d' and its displacement is prevented by the screw t. Under
the casing A is a moulding B which is in connection with the interior of the casing.
The lower
To the lower part of the casing is cast or screwed a suction pipe 7.
brass d' is alone provided with a lubricating hole which coincides with the axis
of the suction pipe.
The hermetical closing of the axle-box is done by means of the leather washers S,
of the iron ring r and of the tightening arrangement ef opg the latter protected
by Patent No 112 of 1894. The bearing is oiled at m and the tightening is done

at m. With axles which have a very short end, that is, when the wheel is near
the extremity, the tightening arrangement (protected by Patent No 112 of 1894)
is lodged in the groove i with this improvement that the groove in the point of
view of solidity and to facilitate the fabrication of grooved sides, is formed by
collar y screwed separately (Figs. 5 and 7) and in this case the cover of the tighten-
ing chamber is likewise suppressed. On second class railways and industrial railways
where the axle trees have no button at their extremity the axle-box is used without
brasses. The air-tightening is effectuated in the manner indicated in Figs. 1
and 5.
In order that the divers axle-boxes used on railways in which semi-brasses
are almost exclusively used, might be transformed in such a way that the
lubricating arrangement or system becomes useless and that the axle journal is
protected. I apply to the semi-brasses D¹ (Figs. 11 and 12) a lower separate
part D to which is also cast a suction pipe / connected by the screws k k or by
rings Z Z (Figs. 13 and 14).
To render these axle-boxes air-tight I dispose a collar y represented in Fig. 7.
Having now particularly described and ascertained the nature of this said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is: :-
1. A mode of execution of the axle-box protected by the Patent No 112 of 1894
distinguished by the casing or axle-box A, being placed directly on the brasses d d¹
and prevented from slipping by the screw t, the axle-box being also provided
with a moulding B in which is placed the suction pipe I cast or screwed to the lower
half d' of the brasses and through which the axle sucks and crushes the oil, owing
to the vacuum produced by its rapid rotation, the air tightening being operated
as already in the Patent No 112 of 1894 by a leather crown (Fig. 5) and a tighten-
ing arrangement ef op g (Figs. 9 and 10) or by a leather washer S (Fig. 1)
and the tightening arrangement ef op g.
2. A mode of execution of the axle-box claimed in 1 distinguished by the
groove Fig. 5 which serves to receive the tightening arrangement being formed
by a collar y to be separately screwed Fig. 7.
3. A mode of execution of the axle-box claimed in 1 distinguished by the casing
or axle-box A. Fig. 8, being used without brasses with axles which have no button
at their forward extremity.
4. The transformation of the different axle-boxes actually in use according to
which I fix on the half brass Figs. 11 and 12, a lower and separate part, pro-
vided with a suction pipe by means of the screws kk Figs. 11 and 12 or by
means of rings Z Z in order to obtain a suction such as mentioned in 1 to protect
the axle trees from injurious shocks and in order to be able to do away with
lubricating pads.
5. The transformation of the different axle-boxes actually in use according to
which I screw a separate collar r, Fig. 4 or y, Fig. (an auxiliary tightening
box) so that the tightening arrangement S and ef pog, Figs. 4, 9, 10 or S and
efpog, Figs. 6, 9, 10 might be hermetical.
