A t'rick wheel comprising a series of a trick comprising l-nib, a. series? of relatively resilient rings paced longitudinally, of

substantially parallel grooves in the periphery of the wheel, a series of lugs interchangeably mounted in said grooves between adjacent rings respectively, a tit on each lug arranged to enter an opening in one of said rings to secure the lug in the ring, andla second titon eachfllngarranged to enter an adjacent opening in the ring to se -l cure-the-lug against movement in the wheel.
