Improvements in Railway Carriage Wheels and the like.
We, ALFRED RITTER VON DUTCZYNSKI, of North Railway Station
Department XII, Vienna II, and GEORGE XANTHO, of Kantgasse 1, Vienna I,
Doctor, both in the Empire of Austria, 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 railway carriage wheels and similar heavy wheels the
web of which, that is to say, the disc between the tire and the hub consists of a
number of concentrically undulated and superposed sheet iron discs, which are fixed
on the hub in a particular manner.
In the annexed drawing
Fig. 1 is a side view of the wheel.
Fig. 2 is a central cross section and
Fig. 3 is the half of Fig. 2 on a larger scale.
As Fig. 3 shows, the middle part or web A consists of a number (in the
drawing 16) of sheet iron discs a which are undulated in the middle part and
which produced by hydraulic pressure in correspondingly shaped steel forms, are
pressed upon another and connected together by means of the rivets f. The centre
of the disc is fixed in the hub in the following manner: The hub consists of two
parts B and C of which the first forms a cylindrical body with flange e, the
cylindrical part corresponding in its exterior diameter to the bore of the web A.
The part d'of the hub B lying above the disc A is at its lower part a little thinner
than the cylindrical part aforesaid, but increases conically outwards and has on its
outer side again the same diameter as the cylindrical part. The web A is placed
with its bore upon the hub B and then a ring C in a red hot condition is placed
over it, this ring having at first the cross section indicated in dotted lines in Fig. 3,
whereupon it is pressed or hammered so that it fits completely to the conical part
of the hub B and when cooling it gives a great pressure upon the nave and will
not come off. The ring receives then a convenient form by means of turning.
The exterior border of the web A is bent rectangularly from the middle of the
thickness of the web to both sides over these parts 99 are placed the border
rings G G hook like in their cross section, which reach with their exterior
borders h h into corresponding annular grooves of the tire H, whilst bolts I or
rivets keep the parts A, G, G, and H together. The fastening between the web A
and the tire H might also be effected in another manner for instance, also as shown
at the hub.
Having now particularly described and ascertained the nature of this said inven-
tion and in what manner the same is to be performed we declare that what
we claim is :-
1. A wheel, in which the web between the hub and the tire consists of several
sheet iron discs which pressed upon another and undulated in their middle part
are connected together by means of rivetting.
2. In a wheel with web as described in Claim 1, a hub consisting of a cylindrical
body B which has on one side a flange and is formed conically on the other side

page_text: upon which cylindrical body is placed the web A whereupon a red hot ring is
placed and pressed upon the conical part.
