Improvements in Elastic Wheel Tyres and in Felloes or Rims
therefor.
I, JOHANN KLAPKA, of Kerepesi-Ut 34, Buda Pesth, in the Kingdom of Hungary,
Carriage Builder, 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:-
The elastic wheel tyres hitherto in use have the disadvantage of being very
troublesome to take off and put on, so that damage to the tyre is frequently
unavoidable, and the tyres are quickly worn out which renders them very
expensive.
The object of the present invention is improvements in elastic tyres in which
the above mentioned disadvantages are entirely or partially removed.
In the accompanying drawings the improvements are illustrated in various
constructional forms.
Figures 1 to 17 show various forms of the rim of the wheel in sections which
enable the elastic tyres to be mounted and dismounted without injury to the
tyres.
Figures 18 to 34 show. many constructional forms of elastic tyres in sections.
In Figure 1, a is the felloe of the wheel, on which the usual iron tyre c is
shrunk. The elastic tyre bis simply pushed on sideways and secured in its
position by means of screws e, and in order to support the screw heads over the
elastic tyres b, an iron or steel hoop d is arranged.
In Figure 2 is illustrated an offlinary wheel with felloe a and iron hoop which
is provided with an elastic tyre 6 and iron or steel protecting hoops d. For
fixing the elastic tyre rings fare arranged on each side of the felloes, which
rings are fastened to the felloes by means of the screws g. The edges of the
hoops & project between the felloes f and have sufficient play to enable them to
move freely.
In Figure 3, an angle-shaped ring i is fastened to the felloes, on which ring
the elastic tyre is fixed with an angle shaped iron ring and screws g. The
elastic tyres can likewise be provided with an iron or steel supporting tyre, or may
even be employed without it.
In Figure 4 an elastic tyre bis drawn upon the iron tyre e of the ordinary
wheel, which is surounded outwardly by the angle shaped iron rings i and the
flat iron rings k which are held together by means of screws.
Leather tyres m are fastened on the angle shaped iron rings by bronze
rivets n. The rivets n are made of soft material in order that they may be worn
down together with the leather.
In Figures 5 and 6 (6' being a side elevation on a small scale) an elastic tyre b
is pushed sideways on the iron tyre c of the ordinary wheel which is fixed in such
a manner by means of clips l and screws g that the clips are fastened on the one
hand to the felloe a, and on the other hand to the elastic tyre b.
In Figures 7 and 8 the elastic tyre b is fastened between two angle shaped

page_text: iron rings i and it in the same way as in Figure 3. The iron angle ring i rests on
springs o which are inserted between iron angle rings II' in a similar manner to
that in which the iron angle rings i, are arranged.
The outside iron angle piece I forms the felloe of the wheel to which the spokes
are fixed in the usual manner.
Figure 9 shews a simplified form of the tyre fastening shewn in Figure 3. In
this modification a simple flat iron hoop takes the place of the angle-shaped
iron rim aforesaid.
Figure 10 is a further modified form of this construction (Figure 9) in which
the rings and all are provided with turned-in edges and the junction of the
rings and is constructed to overlap.
Figure 11 shews the same arrangement as Figure 3 with turned-in edges p.
In Figure 12 a flat iron ring f is arranged in place of the flat iron rim shewn
in Figure 9. It is also fixed to the wheel felloe a.
Figure 13 shews these devices carried out on both sides which is applicable to
an ordinary wheel with ring a and iron hoop c, similar to the construction shewn
in Figure 2.
Figure 14 shews a device similar to that in Figure 3, in which the iron angle-
shaped piece i forms the felloe of the wheel.
Figure 15 shews the same device with turned-in edges p.
Figure 16 shews a similar device to that in Figure 13 with iron fellocs instead
of wooden felloes.
Figure 17 shews the same construction as Figure 7, with wooden felloes in
which the flat iron pieces F are arranged instead of the iron angle pieces II¹,
similar to the device in Figure 2.
In all these constructions of the wheel, rubber tyres or other elastic tyres may
be employed instead of the elastic tyres 6 shewn.
In the Figures 18-34 are illustrated special constructional forms of such
elastic tyres as can be made more cheaply than rubber tyres.
In Figure 18 a wooden rim s is formed from one piece or put together from many
parts. Leather tyres are fastened on this wooden rim by means of wooden or
iron pins.
Figure 19 shews a tyre built up of strips of leather, which are held together by
means of wooden or iron pins.
In Figure 20, u is a U-shaped tanned leather tyre closed underneath by a
leather ring v.
The hollow space A is filled with any clastic material (rubber,
horeshair, hemp and the like). t is a protective ring against wear and tear of
the aforesaid tyre.
In Figure 21 is a leather tyre of U-shaped section, which is provided with a
woven lining w¹ (linen or the like). The hollow space of this tyre is filled with
cork, which is perforated throughout its whole length. In two places of the tyre
are arranged sidewise perforations z so that water from time to time can be
supplied to the filling of cork which soaks the cork and thus preserves its
elasticity.
Figure 22 shews a similar construction to Figure 20 in which the hollow space A
is filled with cork.
Figure 23 shews the same construction with iron or steel protective tyres t.
Figure 24 shews a similar construction to Figure 21, in which the hollow space
is filled with leather.
Figure 25 shews the same construction with wood filling.
Figures 26 and 27 (side elevation) shew two U-shaped rings u connected by a
longitudinal suture.
Figure 28 is the same construction as Figure 21, with U-shaped rubber tyres.
Figure 29 shews an elastic tyre b with iron or steel hoops y arranged at the sides
for strengthening the elastic tyre b.
Figure 30 shews a rubber tyre b with grooves a fitted in to which an iron or
steel protecting hoop is fastened by means of screws a¹.

page_text: Figure 31 shews a rubber tyre b with a hemp rope r which is rivetted to a flat
iron ring T. The head of the rivet is deeply embedded in the rope in order to
protect the rubber from injury.
Figure 32 shows the same device with iron angle-shaped rings T.
Figure 33 shows the same device with U-shaped rings T.
Figure 34 shows the same device as Figure 26 in which a leather protective
ring t is arranged.
