PROVISIONAL SPECIFICATION.
Improvements in Wheels suitable for Velocipedes, Perambulators,
and the like.
I, JOHANNES DAME, of Neuwerkstrasse 9, Erfurt, Germany, Ironmonger, d
hereby declare the nature of this invention to be as follows :-
This invention relates to wheels suitable for velocipedes, perambulators and the
like. According thereto the outer rim which is provided with an elastic tyre is
not rigidly connected with the spokes, but through the medium of springs arranged
between the said outer rim and an inner rim, with which the spokes are connected
in any well known manner. Wheels according to this invention are designed to
supersede wheels with pneumatic and other elastic tyres as heretofore constructed.
In the accompanying drawings
Fig. 1 is a side, elevation of a wheel according to this invention.
Fig. 2 is a cross section of the same.
Figs. 3 and 4 illustrate to a larger scale in cross section and longitudinal section
respectively, the elastic connection of the outer rim with the inner rim.
The inner rim a is connected by spokes & with the nave e in any suitable way.
The outer rim d is provided on each side with a flange e between which is
arranged a rubber tyre f which is cemented in the groove formed by the said
flanges on the rim d. The connection of the inner rim a with the outer rim d is
effected by means of compression springs g which are fixed to the rims by means of
screw bolts h and nuts i, the said springs being sufficiently strong to transmit the
rotary motion of the inner rim to the outer rim d, and sufficiently elastic to
completely take up the jolts caused whilst riding over uneven roads, without
transmitting such shocks to the spokes and nave.
Wheels according to this invention are cheaper to manufacture than wheels the
running surface of which is a hollow rubber tube filled with air, and they can be
easily repaired when necessary.
Dated this 15th day of June 1892.

COMPLETE SPECIFICATION.
Improvements in Wheels suitable for Velocipedes, Perambulators,
and the like.
I, JOHANNES DAME, of Neuwerkstrasse 9, Erfurt, Germany, Ironmonger, 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 wheels suitable for velocipedes, perambulators and the
like. According thereto the outer rim which is provided with an elastic tyre is
not rigidly connected with the spokes, but through the medium of springs arranged
between the said outer rim and an inner rim, with which the spokes are connected
in any well known manner. Wheels according to this invention are designed to
supersede wheels with pneumatic and other elastic tyres as heretofore constructed.
In the drawings filed with my Provisional Specification,
Fig. 1 is a side elevation of a wheel according to this invention.
Fig. 2 is a cross section of the same.
Figs. 3 and 4 illustrate to a larger scale in cross section and longitudinal section
respectively the elastic connection of the outer rim with the inner rim.

page_text: The inner rim a is connected by spokes 6 with the nave e in any suitable way.
The outer rim d is provided on each side with a flange e between which is arranged
a rubber tyre f which is cemented in the groove formed by the said flanges on the
rim d. The connection of the inner rim a with the outer rim d is effected by means
of compression springs 9 which are fixed to the rims by means of screw bolts and
nuts the said springs being sufficiently strong to transmit the rotary motion of the
inner rim to the outer rim d, and sufficiently elastic to completely take up the
jolts caused whilst riding over uneven roads, without transmitting such shocks to
the spokes and nave.
g
Wheels according to this invention are cheaper to manufacture than wheels the
running surface of which is a hollow rubber tube filled with air, and they can be
easily repaired when necessary.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The hereinabove described improvements in wheels for velocipedes, perambu-
lators and the like in which an inner rim a is elastically connected with an outer
rim d by means of compression springs g.
2. In wheels of the kind referred to in Claim 1, the arrangement of side flanges e
on the outer rim d for holding the rubber tyre f which is cemented in the groove
formed thereby substantially as described.
