ABSTRACT:
An improved tumbler for use in pad driven machinery or the like utilizes a plurality of replaceable wear members mounted to a reel assembly on the conventional tumbler hub. The wear members engage the cleats of the pads to impart relative motion and bear the brunt of the wear generated thereby. The wear members are designed to wear faster than the cleat or reel assembly and are mounted for relatively easy replacement, thus eliminating replacement of worn tumblers.
