Improvements in Tires for Cycles and other Vehicles.
We ALOYSIUS JOSEPHUS JOHANNES LINDNER, Cork Manufacturer, and
MAURICE ADLER, Student, both of Singel 417, Amsterdam in the Kingdom of
the Netherlands, 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 tires for cycles and other vehicles, and consists in the
improvements constituting the tire hereinafter described, to which we have given?
the name "Arrektos."
Reference being made to the annexed drawing,
Fig. 1 is a side elevation of the tire, or a portion thereof, with exterior envelope-
removed showing the tire attached to the rim.
Fig. 2 is a longitudinal section on line 2. 2. Fig. 3.
Fig. 3 is a cross section through the tire, rim, and envelope on line 3. 3. Figs. 1
and 2.
.3
Fig. 4 is a side elevation of the tire when under compression, the exterior:
envelope being removed.
The tire consists of three parts or layers, an inner layer of cork, as a preferable-
material, B, having its outer surface serrated or corrugated so as to form alternately.
raised ridges 6 and hollows b¹; a middle layer C consisting of a flat band of gutta
percha or equivalent rubber composition; and an outer layer A, preferably of
cork having its inner surface serrated or corrugated so as to form alternate ridges a
and hollows a¹.
These three parts are assembled as shown in Fig. 1 so that the ridges a are above
the hollows band-the ridges b under the-hollows.a¹..
The inner layer B is secured to the rim, and by preference we use a hollow
rim D with a flat bed surface for the tire and turned up edges bent inwards at d to.
secure the tire. to the rim.
The faces of the ridges a and b are cemented to the band C.
This tire, we enclose in an envelope E which may be of usual construction being
made thicker at the sole e and attached on the rim for instance at e' by cement, or
any of the known methods of fastening such envelopes.
When this tire is compressed by contact with the ground the layers A and B are-
pressed together and with the band C assume the position shown in Fig. 4. When:
the pressure ceases the parts return to their original position as in Fig. 1 owing to.
the elasticity of the band C.
The resiliency of this tire and its suitability for different vehicles, road surfaces,
or weights of load, may be varied by varying the thickness of the band C, by
varying the tension of this band which may be put on loosely or under tension, by
altering the pitch or distance from centre to centre of the teeth and making them.
broader or finer; or lastly by making the teeth higher or lower.
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. In a tire for cycles or other vehicles the combination of an inner layer B.
serrated on its outer surface, a resilient middle layer C and an outer layer A.
serrated on its inner surface, the serrations of the layer A being alternated with.
regard to those of the layer B substantially as and for the purpose set forth.

page_text: 2. In a tire for cycles or other vehicles, the combination of an inner layer B
serrated on its outer surface, a resilient middle layer C cemented to the summits
of the said serrations, and an outer layer A serrated on its inner surface and having
the said serrations cemented to the middle layer C in positions intermediate between
the serrations of the layer B substantially as and for the purpose set forth.
3. In a tire for cycles or other vehicles, the combination of a layer B transversely
serrated on its outer face, an intermediate resilient and in normal position flat
layer C, and an outer layer A transversely serrated on its inner face, the latter
serrations being alternated with the former substantially as and for the purpose set
forth.
4. In a tire for cycles or other vehicles, the combination of an inner layer B
having on its outer face transverse ridges 6 and transverse recesses 61 between said
ridges, the latter being wider at the mouth than the outer faces of the ridges; an
intermediate resilient band C in contact with the outer faces of the ridges; and an
outer layer A having on its inner face transverse ridges a and transverse recesses a¹
between said ridges, the faces of the ridges a being in contact with the outer face
of band C at surfaces opposite the recesses b¹, substantially as and for the purpose
set forth.
5. In a tire for cycles or other vehicles the combination of a serrated inner
layer B, a resilient middle layer C and a serrated outer layer A arranged as set
forth, with an enclosing envelope E, the whole substantially as and for the purpose
set forth.
6. In a cycle or other vehicle, the combination of a hollow wheel rim D with
inturned edges d; with a tire composed of serrated inner layer B, resilient middle
layer C and serrated outer layer A arranged substantially as set forth; and an
exterior envelope E, the whole for the purpose described.
