EDWIN AMBROSE BRYDGES of the Firm of Brydges & Co. Engineers and
Patent Agents of 73 Königgrätzer Str. in the City of Berlin and German Empire
and 6 St. Leonards Terrace, Upton in the County of Middlesex. "IMPROVEMENTS
IN METALLIC WHEELS FOR VEHICLES." A communication from Wilhelm Richter
of the City of Berlin in the German Empire aforesaid.
This Invention relates to improvements in metallic wheels for vehicles. These
said wheels consist of the following parts:
a) The nave or hub into which the axle box is slid or fitted.
b) The spokes which are fixed in the nave and are at the opposite end provided
with screw threads or screws and nuts.
c) The tyre provided on the inner surface with a substitute for the ordinary felly
consisting of angle iron.
The said metallic wheels are put together or mounted in the following manner:
After the screws to the spokes have been screwed into the nuts, the nave or
hub with the spokes inserted in the same can be placed inside the angle iron felly
attached to the tyre and the nuts turned until the heads of the screws are pressed
hard against the said angle iron felly.
As soon as the spokes are under proper tension and the wheel adjusted, the
spaces between the nuts and the heads of the screws are filled out with a suitable
molten metallic composition which is then well forced in by means of suitable
pincers, nippers or other suitable implement so that the pressure is removed from
the screw threads. This said method of attaching the spokes to the felly and to
the nave or hub enables single spokes to be removed without having to take the
whole wheel apart.
Another method of fastening the spokes to the felly consists in attaching a cap
to the outer end of each of the spokes which said cap is fitted with suitable
bearings or brasses or can be made of such form that extra brasses are not
required. This said second method consists further of a wedge of suitable width

wedge has originally one straight surface but after the same has been driven in
tight between the felly and the cap or bearing it assumes such a form that a
loosening of the wedge or a retrograde movement of the same is absolutely
impossible.
A layer of elastic material can be inserted if considered advisable in order that
the spokes may be better able to withstand concu-sion.
In case one of the spokes should after considerable wear and tear get loosened
it is only necessary to drive the wedge a little further in when the spoke will be
as firmly fixed as when the wheel was new. I prefer to make the spokes of
tubing although wood; rod or other iron or other suitable material can be
employed.
The nave or hub is so formed that the ends of the said spokes fit into suitable
cavities in the nave or hub or the said hub or nave can be provided with short
hollow arms to receive the said spokes.
