Improvements in Axle-boxes for Railway and Tramway Carriages
and the like.
I, FREDERICK WILLIAM GOLBY, of 36, Chancery Lane, in the County of Middle-
sex, Patent Agent, do hereby declare the nature of this invention and in what
manner the same is to be performed, as communicated to me by Herrmann Otto,
of I, Zittauerstrasse, Görlitz, Germany, Merchant, to be particularly described
and ascertained in and by the following statement:
This invention which relates to axle-boxes for railway and tramway carriages
and the like consists substantially of an axle box, which is displaceable horizontally
in two directions i.e., in the direction of travel, as well as at a right angle thereto.
and is returned to its normal position by means of spiral springs and a guiding
frame, which is connected with the bearing spring, in order that a complete radial
adjustment of the axle end may be secured at every bend of the road, and, thereby
the wear of the tyres and rails considerably reduced, when running on curves.
Furthermore, in consequence of the radial adjustment of the axles the distance
between them when running on a curve will be increased thereby a smoother
travel is obtained, and the carriage is prevented from running off the track.
Fig. 1 of the accompanying drawings is a vertical section of an axle box con-
structed according to the invention,
Fig. 2 a horizontal section &
Fig. 3 is a vertical cross section of same.
Fig. 4 is a front view elevation of same,
Fig. 5 is a diagram showing part of the track and the radial adjustment of
the carriage axle on a curve.
The fixed guiding frame a on which the bearing spring b is arranged, is fitted
with two spiral springs c lying opposite to one another at a right angle to the
axle, and bearing on the opposite sides of the axle box d so that the end of the latter
may be displaced in the direction of travel. The axle box d is fitted with two
spiral springs e arranged parallel to the axle to enable the end of the latter to be
displaced in the direction of its length i.e., at a right angle to the direction of
travel.
The construction of the present axle box differs essentially from those hitherto
known, in the fact that the actual axle box is displaceable horizontally in a fixed
guiding frame a in the direction of travel as well as at a right angle thereto.
The axle box is closed at the end by a cover g which is kept closed by means of an
iron piece or pivotted strap f. This last mentioned piece is screwed up tightly
by means of a winged screw i. A lubricating apparatus prevents the axle from
becoming hot in the axle bearing. By removing the cover g, the lubricating
vessel can be conveniently removed. Packing rings, or the like, arranged at
suitable spots prevent dust, dirt, or other matters, from penetrating to the axle
bearings.
The axle box herein before described can be applied to all carriages running on

of the axle, is purely constructional in its nature.
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: :-
An axle box for railway- and tramway carriages and the like distinguished by
the actual axle box being horizontally displaceable, in a fixed guiding frame, in
the direction of travel, as well as at a right angle thereto, and brought back again
to its normal position by spiral springs, for the purpose of securing a complete
radial adjustment of the axle end at all windings of the road, in order thereby
to reduce considerably the wear of the tyres and rails, when running on curves,
as well as by reason of the radial adjustment of the axle to ensure an easy running
of the carriage, and, as far as possible, to prevent the carriage from running off
the track substantially as described.
