SIMPSON SHEPPARD Sculptor 10 Alphonsus Avenue Drumcondra and JAMES
RISPIN Merchant 20 Leinster Road Rathmines both in the City and County of
Dublin do hereby declare the nature of this invention to be as follows:-
We put on the wheel au iron or steel tyre. The wire spokes are screwed or
riveted to the iron or steel tyre in the iron or steel tyre is any required number of
holes to screw or make fast the tubes. In the tubes we put spiral or other suitable
springs. In the tubes and on the spiral springs is an iron rod or plunger with a
suitable shaped end on it for the rubber tube to work on. We make a round hoop
of steel the diameter suitable for the wheel. The hoop is left open. The end of
the open hoop is put into rubber tubing. The rubber tubing is pushed around the
steel hoop. The ends of the steel hoop is brought together and suitably fastened.
The steel hoop is covered all around with the rubber tube. The tubes with the
spiral springs iron rod or plunger with a suitable end for the rubber tube to work
on the rubber tube is put in its place and the other end of the iron rod or plunger
works out and in. On the end of the tube nearest the centre of the wheel is a
screw that keeps the rubber tyre in its proper place.

An Improved Wheel for Bicycles, Tricycles, and other Vehicles.
SIMPSON SHEPPARD, Sculptor, 10 Alphonsus Avenue Drumcondra, and JAMES
RISPIN, Merchant, 20 Leinster Road Rathmines both in the City and County of
Dublin, 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 relates to an improved wheel for bicycles tricycles and other
vehicles.
We attain these objects by the mechanism illustrated in the accompanying
drawings, in which―
Fig. 1 is an elevation of a wheel with spiral springs ;
Fig. 2, is an elevation of a wheel with a number of semi-circular springs;
Fig. 3, is an elevation of Fig. 2 with some of the spokes removed;
Fig. 4, is a plan of the semi-circular spring;
Fig. 5, is an enlarged detail of a part of the steel tyre, semi-circular spring and
the india rubber tyre.
Similar figures refer to similar parts throughout the views.
We put on the wheel, an iron or steel tyre; and the wire spokes are screwed or
riveted to the said iron or steel tyre. In the said iron or steel tyre is any required
number of holes to screw or make fast the tubes 1. On the tubes we put a spiral
spring or springs 2, around the outside of the tubes, or the spiral springs may
inserted in the inside of the said tubes. On the spiral springs is an iron rod or
plunger 3, with a suitable shaped end on it for the rubber tube to work on.
make a round hoop of steel the diameter suitable for the wheel. The hoop is left
open. The end of the open hoop & is put into the rubber tubing. The rubber
tubing is pushed around the steel hoop 8 when the ends of the steel hoop 8 are

together and fastened, the steel hoop 8 being thus covered all round with the rubber
tyre. The tubes with the spiral springs and the plunger is provided with a suitable
end for the rubber tube to work on. The rubber is fixed in its place and the other
end of the plunger in the tube with the spiral spring works out and in. On the end
of the tube nearest the centre of the wheel is a screw or split key 4, to keep the
rubber tyre in its place. We can also apply eliptic springs 5, as in Figs. 2, and 3,
between the inner and outer tyres. The eliptic springs are properly fastened to
the steel tyre 6, with the ends of the said springs attached to the rubber tyre.
The steel hoop that is covered with the rubber tube can be laped around with
rubber cord.
In Fig. 1, we show a double rimmed wheel with an inner and outer rim, the
inner rim 6, has any required number of holes for the tubes. The tube 1, is flanged
at one end and the flanged ends rests on the rim 6. The tubes 1, is put into
the holes in the rim 6. On the tubes 1, we place nuts to screw up against the
inner rim 6, the said rim being situated between the flange on the end of the
tube and screw nut. In the tubes 1, we form a slot in order to permit a split.
pin 4, to pass through; and the spiral springs 2, are placed around the outside of
the said tubes. The object of the split pin 4, being to keep the spring 2, in its
place. The iron rod or plunger 3, (the end of the plunger) is put into tube 1, and
in the end of the plunger 3, is a hole for a split pin to pass through the slot. In
the tube 1, the split pin is put into the slot and passes through the hole in the end
of plunger 3. The spiral springs 2, being pushed up tight towards the pin in the
end of the plunger so that the pin put through the other end of the tube may
keep the spring tight on the end of plunger.” The plunger with suitable ends
keeps the outer rim or tyre in its place.
In Figs. 2, and 3, we describe a double rimmed wheel having an inner and outer
rim. The inner rim 6, is provided with any required number of holes for the
purpose of fixing the eliptic springs 5. They are made fast with a set screw and
nut that passes through the hole in the eliptic springs, and the inner rim 6, and
screwed tightly together.
To put on the outer rim 7, we screw one of the cliptic springs 5, on the inner
rin 6, and place the outer rim 7, in its position on the spoon shaped ends of the
eliptic spring 5, and so proceed to fix the required number of eliptic springs in the
same or a similar way.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is :-
1. The combination of the inner and the outer rims, with the plungers, tubes and
springs, for a bicycle, tricycle or other vehicle wheel, substantially as herein
described and according to Fig. 1, of the accompanying drawings.
2. In a wheel for a bicycle, tricycle or other vehicle, the combination of the
inner and the outer rims, with the eliptic springs, substantially as herein described
and according to Figs. 2, 3, 4, and 5, of the accompanying drawings.
