Improvements in or relating to Wheel Tyres.
We, STANLEY COOPER PEUCHEN, of 393 Sackville Street, City of Toronto,
in the County of York and Province of Ontario, Canada, Manufacturer, and
PETER CLARKE, of 11 Washington Avenue, in the said City of Toronto,
Gentleman, 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 our invention is to devise a tyre for the wheels of bicycles and
other vehicles, which will possess all the advantages of an ordinary pneumatic tyre
without its liability to be punctured or become leaky, and which will at the same
time be both light and cheap, and it consists, essentially, in placing an outer rim
with a rubber tread outside of and concentric with the rim of the wheel and
connecting it with the said rim by tension springs, means being provided whereby
the tension of said springs may be adjusted, substantially as hereinafter more
particularly described.
Figure 1 is an elevation of a bicycle wheel provided with our improved tyre,
only four of the connecting springs being shown.
Figure 2 is a cross section through the tyre showing a spring and its
connections.
Figure 3 is a longitudinal section of the same.
Figure 4 is a perspective detail of the spring-holding plate of the outer rim with
its connecting pin.
Figure 5 is a perspective detail of the adjustable double hook which is connected
to the inner rim or felloe.
Figure 7 is a perspective view of an alternative form of this hook.
In the drawings, like letters of reference indicate corresponding parts in the
different figures.
The detailed construction of our invention is best seen on reference to Figures 2,
3, 4, 5 and 6 in which
A is the inner rim or felloe, to which the spokes of the wheel are connected in
the usual manner. B is an outer rim concentric to the former, and preferably
covered with a rubber tread C. Both these rims are preferably made of wood,
though we do not confine ourselves to the use of this material.
D is a metal plate connected to the outer rim B, by means of a pin E (see
Fig. 4), which passes through the rim and is held in place by the counter-sunk
nut F. This pin passes through a hole in the plate D, which is held in position
thereon by means of the cotter-pin G, (see Fig. 3) or in any other suitable
manner.
The plate D, is provided with two grooves H, to receive the parts of the
spring I, intended to lie therein. The edges of these grooves are curled
outwardly to reduce the possibility of chafing the spring. The outer edges of
these grooves are a sufficient distance from the inner side of the outer rim to allow
of the spring being pushed into the grooves without removing the plate D,
(see Fig. 3).
J is a pin passed through the inner rim A and held in position by a counter-
sunk nut K. A nut L is screwed thereon and is provided with a flange M. A
ring N, having a double hook O, integral therewith is slipped over the nut L, and
rests on the flange M.
P is a jamb nut, by means of which the nut L, may be held in any desired
position on the pin J, (see Fig. 6).

page_text: In Fig. 5, the spring is shown, which is preferably formed of a number of fine
rubber springs covered with a continuous braided covering. We mention this,
which is a commercial article, as being the best for our purposes. Of course any
durable rubber spring would answer the purpose. This spring is looped, as shown,
the loops a, lying in the grooves H, and the loops b, being caught on the hooks O.
When thus placed in position, any desired tension may be given to the spring by
adjusting the nut K, which may be either of hexagonal form as shown, or else
provided with butter-fly wings. A series of these springs and their connections
are of course placed around the rim, preferably between every other spoke, but a
smaller number may of course be found sufficient.
In Fig. 7 is shown an alternative form of connection for the hooks C. The
hooks are connected directly to the end of the pin J, which passes through the
bridge Q, and is adjusted by means of the nuts S. The connection of the spring
to the outer rim B, might also be considerably varied without departing from the
spirit of our invention.
As shown in the drawings, the spring I, passes on each side of the inner rim A,
which gives it the best position to withstand side strain on the outer rim B, but of
course it might be arranged in many different ways.
From the above description, it will be seen that we have devised a light, strong
and easily running tyre which is subject to none of the disadvantages of the
ordinary pneumatic tyre. It will also be seen that the tension of any or all
of the springs may be adjusted easily and quickly at any time and that any
damaged spring may be quickly taken off and replaced without interfering with
the others.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed we declare that what we
claim is ;-
1. In a tyre an outer rim and an inner rim or felloe in combination with a series
of tension springs connecting the said rims substantially as and for the purpose
specified.
2. In a tyre, an outer rim and an inner rim or felloe in combination with a series
of tension springs connecting the said rims and means for adjusting the tension of
the same substantially as and for the purpose specified.
3. In a tyre an outer rim and a ninner rim or felloe in combination with a series
of endless tension springs connecting the said rims substantially as and for the
purpose specified.
4. In a tyre an outer rim and an inner rim or felloe in combination with a series
of endless tension springs connecting the said rims and means for adjusting the
tension of the same substantially as and for the purpose specified.
5. In a tyre an outer rim and an inner rim or felloe in combination with a series of
springs connected to the inner side of the outer rim passing round the inner rim
and connected to the inner side of the same substantially as and for the purpose
specified.
6. In a tyre an outer rim and an inner rim or felloe in combination with a series
of springs connected to the inner side of the outer rim passing round the inner rim
and adjustably connected to the inner side of the same substantially as and for the
purpose specified.
7. In a tyre an outer rim having a series of plates D connected thereto each
provided with two grooves H au inuer rim or felloe having a corresponding number
of double hooks O connected to the inner side thereof in combination with endless
tension springs I looped to lie in the grooves G and hooks O substantially as and
for the purpose specified.
8. In a tyre an inner rim having a series of plates D connected thereto each
provided with two grooves H an inner rim or felloe having a corresponding number
of adjustable double hooks O connected to the inner side thereof in combination
