LARS SEVERIN ZACHARIASEN of Christiania in the kingdom of Norway
IMPROVEMENTS IN RADIATING AXLES FOR RAILWAY AND OTHER CARRIAGES
According to my Invention the axles for railway and other carriages are made
to radiate by the use of a separate frame for carrying the usual fittings which
frame is independent of the carriage and connected to it all as hereafter
particularly described and illustrated in the accompanying drawings wherein
similar letters of reference refer to like parts in all the Figures.
Figure 1, Elevation shewing the radiating axle frame placed under the carriage
under frame a.
Figure 2, Transverse section on line u z Figure 1 shewing elevation of axle.
Figure 2 Transverse section on line x. y of Figure 1 and
Figure 3 is plan of same.
Figure 3 plan with carriage under frame removed.
a is the carriage under frame, b brackets fastened to the bottom flange and
stiffened by the bars c. Axle boxes h move in ordinary axle guards i, which
are fastened to a separate frame d, consisting of the necessary longitudinal and
transverse beams and braces put together as shown on drawing or in any other
convenient manner and supported on suitable bearing springs carried by the axle
box, directly or indirectly. This frame is provided with a suitable bracket bat
each corner from which are suspended links f, the other ends of which rest on the
brackets b, on the carriage under frame above described. These movable links
form the sole connection between the carriage frame and the radiating axle frame,
and allow a movement between the two frames. In passing round curves, the
axle frame will take a radial position, while the carriage frame will keep the

page_text: tangential, a movement thus occurring between the two frames causing the links
to change position and thereby forcing the carriage body out of the normal
position. The natural tendency of this to recover itself will cause the axle frame
to return to the normal position as soon as the force which caused its swinging
out cease to act. i.c. when the carriage again enters the straight line.
The weight of the carriage body will thus always tend to keep the axles parallel
on the straight line and prevent overiding in curves. In order to guard against
the axles turning round under the carriage in case of leaving the line or other
accidents, stoppers may be provided on the carriage body at such distances from
the axle frame as will give this frame free movement in all 'curves only aiding as
soon as an over-riding occurs
The links may be hung vertically or inclined as shown on the drawing
according to circumstances may be made of any convenient length and of the form
shown on drawing; or with ball socket or universal joints or in any other way
capable of giving a free movement in one or more directions. The axle frame
may also be made in any suitable way and of any suitable material and may be
adapted to different kinds of springs as circumstances and the different kinds of
carriages may require.

Having now described the nature of my Invention, and how the same may be
carried into practical effect I declare that I claim :—
First: For radiating axles for railway and other carriages, the use of a separate
frame provided with the usual attachment of horn plates, springs axle boxes and
wheels independent of the carriage frame and connected with it by movable links,
_in the manner before described.
Second: For radiating axles the application of novable links for connecting
the two wheeled axle frame with the carriage body, the said links being in the
form of ordinary chain links or of other forms with ends furnished with ball and
socket or with universal joint or with hinge joint or other suitable joint; so as to
permit free motion_in_one or more directions, substantially_as_set_forth.
In Witness whereof I the said Lars Severin Zachariasen have hereunto set
my hand and seal this twenty fourth day of July in the year of our Lord one
thousand eight hundred and eighty three."
