My invention relates generally to wheel structures and more particularly to wheel structures
having demountable rims on which tires are
ing rings l1 and it which are in turn supported
by a pressed fit within element II as shown.

My invention is directed toward the problem
- of simple and easy replacement of worn tires on
a manner suggesting the spokes of a wheel. The |
circumierential edge of the disc portion I is bent
the rubber-tired trucks which are in use about
railway stations and in other industrial uses.
It is important that the change. of tires be ac-
v10 complished quickly and" without extensive and
heavy apparatus. The pressed-0n type of tire
which is frequently met with in industry limits

is duplicated on the other side .0! the disc 901'

movable ring 2i. The ring 24 is secured to the 10
disc portion 3 by a fastening means composed of
bolts 26 and nuts 21 with lock washers of a usual

tus which cannot be widely dismbuted
