These rubber tires or treads are desirable both when the
The embodiment of my invention illustrated is adapted
for use both on a hard surface, land, pavement, ice or the
tricycle is operated on ice or on land ‘or pavements or
like, and in water. It is desired to point out, however,
the like.
The ?xedly connected parts are desirably connected
that certain features relate particularly to use in water and
would be of importance if the tricycle were designed for 50
use only in water. The embodiment of my invention
illustrated comprises the rear Wheels 1-1 and front
wheel 2, all three of which are designed to constitute air
chambers. The rear wheels 1 comprise the rims or treads
3 which are of substantial width, and in the embodiment 55
illustrated are provided with annular reinforcing ribs 4.
The inner and outer side Walls 5 and 6 are of conical
shape and their outer edges or peripheral edges 7 project
beyond the tread 3 and constitute outer walls for the tire
seats 8, the tread being inset to coact with these rim por
tions 7 to provide seats for the tires 9 which are desirably
by solder or welds as indicated at 44 in FIG. 8, for ex
ample, but such connections are not further described.
With the parts arranged as illustrated, the wheels may be
formed of relatively light material and at the same time
are strong and rigid. One of the attained objects is that
the entire structure is relatively light and at the same time
is strong and durable.
I have illustrated and described my invention in a highly
practical embodiment thereof. I have not attempted to
illustrate or describe certain modi?cations and adaptations
60 which might be desirable for particular uses, as the struc
ture illustrated is adapted for use both on land and water
by people skilled in using or manipulating bicycles on
of solid resilient material, although a substantial degree
of resilience is not required.
