This invention relates to amusements devices and par
ticularly to that type of device 'or apparatus commonly
called a Ferris wheel.
It is an object of this invention to provide a novel
Ferris wheel apparatus for use by a single individual
wherein the individual can rotate himself within the
apparatus in a vertical plane and through .a complete
Another object of this invention is to provide a Ferris
wheel apparatus capable of the use described above which
is economical of manufacture, effective and safe in use,
and which is readily assembled and disassembled.

at the other end 34. A roller bearing 36 is `inserted with
avpair of washers 37 and 38 into the open end 34 and
receives one end of a shaft 39 the other end of which
is secured to a bolting plate 41. A spacer 42 is mounted
on the shaft 39 between the plate 41 and the outer
washer 33.
The cage assembly 12 includes .a pair of rectangularly
shaped frames 43 (FIG. 1') and 44 of tubular -material
connected together in aligned relation by a pair of corner
crossbars 46 and 47 at what shall be designated the
top 48 of the cage assembly 12, and by another pair of
corner crossbars‘fà? and S1 at what shall be designated
the .bottom 52 of the cage assembly. The common sides
53 and 5d of the cage frames 43 and 411 are also inter
