Improved Waggon Wheel.
We, BRONISLAW TUROWSKI and JAN ZARSKI, both Mechanicians, of 16, Wlod-
zimierska, Warsaw, Russia, do hereby declare the nature of this invention to be as
follows:
―
The present invention relates to railway waggon wheels, the object of which is
to suppress shocks and to prevent the breaking of the tyres by placing rubber
bands between the rims and the tyres.
These wheels may be constructed according to any type and their rim has a
protruding edge on one side over its whole circumference, and which, with a flat
ring fixed on the other side of the rim by means of bolts, forms a square or
rectangular sectioned groove in which the band of rubber or other suitable matter
is fixed.
The tyre of the wheel is fitted around the rubber band but in such a way
that the said band is not fixed tight against the tyre so that this tyre can turn on
the band during the passage of the waggon in the curves which cause frictions
resulting from the unequal speed of the wheels fixed on the same axle.
The flat ring fixed on the side of the rim, opposite to the protruding edge, is
intended to hold the rubber band and the tyre in order to prevent their slipping
sideways; moreover this ring protects the rubber band from the injurious
influences of the air.
Moreover, a brown coat may be formed on the rubber resulting from the com-
bination of the rust with the sulphur contained in the rubber; but this coat offers
no inconvenience and may easily be avoided by placing a thin band of brass
or other inoxidable metal between the rim and the rabber band and between this
latter and the tyre.
It is evident that the elastic bands, instead of being in rubber, may be in any
other suitable matter or composed of elastic contrivances in metal.
These elastic bands suppress the shocks, allow of the free dilatation of the tyres
and the application of every system of brake; moreover the eventual damaging of
the elastic bands has no prejudicial result.

page_text: We, BRONISLAW TUROWSKI and JAN ZARSKI, both Mechanicians, of 16, Wlod-
zinnerska, Warsaw, in the Empire of Russia, 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 object of this invention is to prevent in railway vehicles the concussions
so frequently occurring and disagreeable to passengers and to protect the tyres
against any rupture, the essential feature of the invention, for ensuring this object
being the arrangement of elastic mountings between the rims and the tyres of
the wheels.
A practical constructional form of the invention is represented in the accom-
panying drawing, in which:-Figure 1 shows two wheels fixed upon a common
axle, one of which being represented in vertical section and the other in side
elevation.
Figure 2 shows a wheel in front elevation partly sectioned, and
Figure 3 a modification in vertical section.
The rim of the wheels A which may be constructed on any suitable system,
is provided on one side with a collar with projecting flange D passing round
the rim and preventing the elastic ring H-which forms the mounting and the
ends of which can be connected or freely touch each other-from lateral slip.
After the tyre C has been put in place, a ring E is screwed by means of screws F
upon the other side of the wheel, that is to say, on the side opposite the collar D;
the said ring E forming with the latter a closed space for the elastic mounting H,
which on the other hand, may also be composed of several separate parts; this
closed space prevents at the same time the noxious action of the atmospheric air
upon the mounting H. The mounting must not however, be tightened against
the tyre and the latter must be enabled to turn on the mounting. It is a known
fact, that on describing curves, frictions are produced which result from the
difference of speed, at which the wheels, located on the same axle, are compelled
to turn.
These frictions and the vibrations resulting therefrom are prevented in this
improved construction owing to the fact that in this case the tyres, as has been
above stated, are enabled to turn on the mountings.
The mountings, instead of being made of indiarubber may also consist of any
other suitable material or may be formed of elastic devices of metal, and the
great advantage resulting therefrom is, that the tyres meet with no resistance
against expansion and contraction produced by changes of temperature, and are not
therefore subject to rupture. If the mountings are made of indiarubber and if—
in spite of the latter lying in a closed space-it should happen, that the inner
rubbed face of the tyre should become covered with rust, a brown layer is formed
upon the india rubber owing to the said rust entering into combination with the
sulphur contained in the indiarubber.
Although this layer does not present any inconvenience, this phenomenon may
be easily prevented by arranging-as shown in Figure 3-between the mounting H
the collar and the tyre; thin annular bands K, K, of brass or other sufficiently
hard metal not subject to rusting. The concussions of waggons in motion may be
considered as resulting from transverse, longitudinal, and vertical vibrations,
and experiments have shown, that the vertical vibrations not only are very
injurious to the health of passengers but are also those which occur most frequently.
These concussions naturally increase with the speed of rotation, so that 300 vertical
concussions per minute are not a rare occurrence. It must therefore be considered

page_text: as a great advantage, that precisely the most noxious concussions can be com-
pletely deadened by the wheels constructed in the manner, described, and it
should be further observed that all kinds of brakes known in practice can be
applied to these improved wheels. Finally any deteriorations occurring in these
elastic mountings are of no serious consequence.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is:-
(1) A waggon wheel in which between the rim, provided with a collar, and the
tyre an elastic mounting is arranged which is covered and fixed in position by
means of a ring to be fastened laterally, and upon which said mounting the tyre
is enabled to freely turn, as set forth.
(2) The new or improved waggon wheels substantially as above described and
represented in the accompanying drawing.
