Improvements in Disc Wheels.
I, ALPHONS KÜCHEN of 9 Hach Street, Bielefeld, in the Empire of-Germany,
Engineer, do bereby 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 a novel construction of wheel suitable for velocipedes,
rope pulleys and the like, and it differs from known constructions inasmuch as it
simplifies manufacture and when used for the construction of the wheels for
velocipedes it facilitates the formation of the rim to carry the tyre.
In the accompanying drawings which illustrate the construction of my improved
wheel :-
―
Figure 1 is a view in side elevation of a wheel suitable for velocipedes.
Figure 2 is a view in transverse section of Figure 1.
Figure 3 is a view in section of a hub with an elastic sleeve or cushion.
Figure 4 is a view in transverse section of Figure 3.
Figure 5 is a view in transverse section, showing another construction of elastic
hub,
Figure 6 is a view in transverse section of Figure 5, and
Figure 7 is a view in transverse section of the wheel on a large scale.
Throughout the views similar parts are marked with like letters of reference.
The novelty of these wheels consists in making the wheel rim and the spokes out
of two stamped steel discs m and m³, as shown by Figures 2 and 7 the said dises
being connected in pairs at suitable points by rivets o. The discs m and m' are so
shaped at their peripheries that when they are fixed together by rivets o, o, etc.,
they form a complete wheel rim n which when the wheel is to be employed as a
velocipede wheel, is shaped to receive the particular type of tyre fit is intended to
carry, which may be fixed to the wheel rim by means of rivets or ferrules o'.
When the wheel is to be used as a rope pulley or belt pulley, the rim is shaped
accordingly..
In order to keep the wheel as light as possible, the sheet metal discs m and m'
may be recessed by stamping out suitably shaped pieces.
In order to be able to construct disc wheels of this kind as elastic wheels, the
discs are connected to or combined with an elastic hub in the following manner :-
The discs are beaded or flanged over at that part adapted to receive the hub, the
said beads or flanges fitting between the flanges g of the hub which are formed
with radial recesses as shown by Figures 3 and 4, with which fillets projecting
from the beadings or flanges of the discs engage. Around the sleeve or barrel of
the hub is placed an elastic sleeve c which completely fills the space between the
two flanges of the hub.
The discs sliding in the recesses b in the flanges of the hub transmit by means of
their beadings or flanges the shocks received by the wheel rim to the elastic
leeve c.
The beadings or flanges on the discs may be guided in various ways according as
the discs are beaded or flanged on the outside as shown by Figures 3 and 4, or
on the inside as shown by Figures 5 and 6 in which construction the flanges g of
he hub carry pins and the discs a and a¹ have oval holes with which the said
þins engage, and this render them capable of transmitting the shocks they receive
o the elastic sleeve c.
I wish it to be particularly understood that I do not limit myself to the precize
letails of construction hereinbefore described and illustrated by the accompanying

page_text: drawing, but that I hold myself at liberty to make such changes and alterations as
fairly fall within the spirit and scope of my invention.
Having now particularly described and ascertained the nature of 'iny said inven-
tion and in what manner the same is to be performed, 1 declare that what I
claim is :-
The improved construction of disc wheel for velocipedes, rope pulleys etc. con-
sisting of two metal dises stamped or otherwise shaped so that beadings or flanges
are formed round the central hole adapted to engage with or fit on the hub, the
said beadings or flanges being adapted to slide radially between the flanges of the
hub and to be guided thereon, and so that their peripheries when rivetted together
form a rim to receive the tyre of the wheel, and of an elastic sleeve placed over the
barrel or sleeve of the hub for the purpose of receiving the shocks received from
the wheel rim, as set forth.
