Improvements in Rubber Tyred Wheels.
We FREDERICK GEORGE HEATII 34 Clive Road, Redditch Manufacturer and
GEORGE FURNISS BAYLIS, of 3 Park, Road Redditch, Mechanical Engineer, both in
the County of Worcester do hereby declare the nature of our said invention and in
what manner the same is to be performed to be particularly described and ascer-
tained in and by the following. statement:-
Our invention has for its object Improvements in rubber, tyred wheels by which
we are enabled to obtain the same amount of resiliency as is obtained by a wheel
having a pneumatic tyre without the liability of puncturing which makes the
pneumatic tyred wheel so objectionable, we are also enabled to securely hold the
rubber tyre in the rim without the use of cement or the like..
In order that our invention may be clearly understood and easily carried into
practically effect we have appended hereunto a double sized sheet of drawings upon
which we have illustrated examples of our improved wheel:
Figure 1 is a perspective side view of a portion of a cycle wheel built according
to our invention.
Figure 2 is a cross sectional view of our rim shewing one method of attaching
the spokes.
Figure 3 is a part sectional side elevation shewing another method of attaching
our spokes.
Figure 4 is a cross sectional view of our rubber tyre.
Figure 5 is an enlarged view of a hub flange shewing the method of attaching
of spokes.
In carrying our invention into practice we form our spokes S from wire with the
coils at the end which is attached to the rim R. The other ends of these spokes
are attached to the flanges H and H of the hub by threading or passing the head. s³
through the enlarged end of the holes or key ways h² which are formed elongated
for this purpose. These key ways may be formed in any position or angle to suit
the arrangement of the spokes. The rim R to which the opposite ends of the
spokes are attached by the nipples ¹ is formed concave in the centre with two
grooves or concave portions 2 and 3 and the enlarged or circular edges. The
nipples which attach the spokes to this rim fit into holes formed in the side por-
tions 2 and 3, and the spokes which are attached at one end to the side cross
over and are attached at their other ends to the flange H and where the spokes
cross one another they are tied or bound together and soldered as shewn at in
Figure 1. In some cases we may secure the spokes to the hub direct without
crossing and lacing and then draw each pair of spokes together near the top and
secure them by soldering or otherwise in a similar manner as shewn at in
Figure 1.
At Figure 3 we have shewn our method for securing the spokes to the rim
without the use of nipples. In this case we form the required number of holes in
the side parts and of the rim and in each of these side parts we place a ring of
wire W having a number of loops 2 which protrude through the holes formed in
the side parts, the ends of the wires may be joined in any desired manner, We

page_text: then form the ends of the spokes which are attached to these loops hook shaped
and these hooked shaped ends are hooked onto the loops w² and then tied or secured
together as hereinbefore described, the coiled ends of the spokes maintaining the
required tension.
At Figure 4 we have shewn a cross sectional view of our improved rubber tyre T
which is formed with the recesses or grooves t¹ and 12 at each side respectively into
which the edges of the rim fit, and the inner convex portion 3 of the tyre fits
into the centre concave portion of the rim. The tyre is preferably formed hollow.
When fitting the tyre into the rim the edges are forced apart and when released
these edges spring back into the grooves or recesses thus firmly and securely
holding the tyre in position.
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:
CLAIMS.
First: The improvements in rubber tyred wheels consisting essentially of the
spokes such as S coiled at their upper ends and secured on each side of the rim and
to the flanges of the hub whether direct or laced and crossed and afterwards tied
together in the manner and for the purpose substantially as herein set forth and
as shewn upon the drawings.
Second: In rubber tyred wheels forming the spokes with a spiral coil at their
end nearest to rim and securing the same in position in the manner and for the
purpose substantially as herein set forth and as shewn.
Third: In rubber tyred wheels securing the spokes to the rim by wires having
a number of loops projecting through holes formed in the said rim to which the
spokes are attached in the manner substantially as herein set forth and as shewn.
Fourth In rubber tyred wheels forming key ways such as 2 in the flanges
of the hub in the manner and for the purpose substantially as herein set forth and
as shewn.
:
Fifth In rubber tyred wheels forming the rim with two side portions such
as 2 and 3 the centre portion being formed concave and having enlarged or cir-
cular edges such as in the manner and for the purpose substantially as herein
set forth and as shewn upon the drawings.
Sixth In rubber tyred wheels forming the tyre with the grooves or recesses
such as t¹ and 2 around its sides for the purpose substantially as herein set forth
and as shewn.
Seventh-In rubber tyred wheels securing the tyre to the rim of the wheel by
forming enlargements on the edges which take into grooves or recesses formed in
the sides of the tyre in the manner substantially as herein set forth and as shewn.
