Improvements in or relating to Elastic Tyres for Wheels.
PIERSE FINUCANE Gent 19 Pembroke Road Dublin JOHN HENRY RYAN Civil
Engineer 22 Nassau Street Dublin do hereby declare the nature of this invention
to be as follows:-
An improved mode of constructing tyres for wheels which consists in having
the rim of the wheel made hollow semicircular square or angular in section or of
such a form as will permit of a spring or springs or a piece of rubber or other
elastic material solid round or tubular in form being placed therein to act as
a cushion; on the outside of this latter is to be placed a hoop piece to act as the
tyre proper of the wheel, composed of steel, iron or any metallic substance, of
sufficient thickness to fill up the space between the sides of the rim and the
cushion, the hoop piece or tyre to be in one piece or continuous or in one or
more segments; in which latter case the ends of each segment are to be cut
with a right and left handed screw alternately so as to engage a nut of same
thickness or diameter as the hoop (so as to be flush with the same) this nut is to
be also cut with a left and right handed screw which is to fit flush on the said
Screw ends of the segment or segments of the hoop or by some other means so
as to draw the said ends together thereby causing the hoop to be tightened on
the cushion and rim and so forcing itself into place between the sides of the
rim; in the former case (that is where the hoop would be in one piece or con-
tinuous) and where required to be put on an ordinary wheel of a vehicle an
inner and outer plate is to be attached to the felloe so as to form the groove in
which is to be placed the said elastic cushion or spring one of such plates to be
so attached as to be capable of easy detachment and so to allow of the cushion
and hoop to be removed at will.

We PIERSE FINUCANE, of 19 Pembroke Road Dublin Esquire, and JOHN
HENRY RYAN of 22 Nassau Street Dublin Civil Engineer 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:-
-
Our invention consists of improvements in the construction of wheel tyres for
all classes of vehicles such as railway and tramway rolling stock, omnibuses,

page_text: carriages motor cars, cabs, carts and such like, and has for its object the imparting
to such wheels a resilient, elastic or spring action and at the same time lessening
the noise usually caused by such wheels of ordinary construction when traversing
streets, roads or rails, it is also adaptable in a modified form to the wheels of
bicycles and tricycles wherein a tyre of metal or other hard and suitable substance
is always in contact with the surface of the streets roads or rails, thereby causing
less wear and tear and so preserving the life of a wheel, and so rendering the
air tube unpuncturable
The nature of our invention and the manner in which the same is to be per-
formed or carried into practical effect will be readily understood on reference
to the sheet of illustrative drawings hereunto annexed, the same reference letters
being used the indicate the same or corresponding parts where shown, and the
following explanation thereof.
Fig. I on the drawing is a section and Fig. 5 is a side view of a segment of
the rim of a wheel broken away, illustrating one method of applying our inven-
tion to any road vehicle wheel, we place on the periphery of the felloe A a
tubing B of rubber or other flexible material of suitable size and shape with a
valve tube attached for inflating the said tubing with air, and on the periphery
of the said tubing we place a metal ring or tyre D which forms the outer tyre
that comes in contact with the roadway when in use. The outer ring or tyre D,
the felloe A and the tubing B are all kept in position by side plates G G, which
at the same time allows of a certain freedom of movement of the tyre in the radial
direction. The aforesaid side plates G G are fixed in their places by bolts, nuts,
or screws II into or through the felloe A of the wheel.
Fig. 2 is a section illustrating the application of a solid piece of rubber Mor
other flexble material in place of the inflated tubing B herein described with
reference to Fig. 1.
Fig. 3 is a section and Fig. 7 is a side view of a segment of the rim of a wheel
broken away showing the application of our invention to bicycle or tricycle wheels
whereby a tyre D of metal or other hard suitable substance is always in contact
with the road surface, in order to keep the tyre in place we construct the periphery
or rim of the wheel of two pieces of metal shaped in section in some such seg-
mental form as is shown in drawing and lettored G G with lips or flanges FF
at top and bottom or at ends of each segmental section so as to enclose the tyre D
at the top and the spokes of the wheel at the bottom, the said lips or flanges are
secured together at the bottom by bolts I, I, the two said segments us bunt
up form a rim for a wheel and in the hollow H thus formed is inserted a
tubing B of rubber or other flexible material with a valve tube attached for
inflating the said tubing with air.
Fig. 4 is a section showing the application of our invention to the wheels of
railway or tramway rolling stock wherein we place in the space between the
under surface of the tyre D and the nave or boss of the wheel a set of metal
springs S either helical or of other form, the tyre D the springs S and the boss K
are all kept in position by side plates G G similarly as described with reference
t. Fig. 1; India rubber tubing either hollow or solid may be substituted for
the metal springs S as described with reference to Figs. 1 and 2. Fig. 6 is a
side view of a segment of the rim of a wheel with one of the side plates G
broken away in ander to show the application of our invention to the wheels of
ordinary vehicles wherein we place in between the under surface of the tyre D
and the felloe A a set of metal springs T flat or of other form, the tyre, springs
and felloe being all kept in position by side plates G G similarly as described
with reference to Fig. 1.
Having now particularly, described and ascertained the nature of our inven
tion and in what manner the same is to be performed, we declare that what we
claim is:-
Improvements in the construction
or arrangement of ranta

page_text: elastic tyre for wheels having a rim or tyre of metal or other hard substance in
combination with an elastic medium such as metal springs india rubber either
tubular or solid, or other elastic substance, and when an air tube is used it is
rendered puncture proof, substantially in the manner and for the purpose herein-
before set forth and described and illustrated by drawings annexed.
