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.
Claims13
An improvement in a drive tumbler moving a drive pad wherein said drive pad includes a plurality of drive cleats which are engaged about the circumference of said tumbler, said tumbler including a plurality of radially extending support members mounted on a central hub for connection to a drive mechanism, the improvement comprising:
- (a) a circumferential reel member defining a plurality of angularly spaced outwardly facing openings therein said openings having a dimension substantially larger than said drive cleats;
- and
- (b) a plurality of wear members detachably affixed within each of said openings having an outwardly flared opening formed therein for receiving said cleats.
Apparatus for reconditioning a worn drive tumbler for a pad drive comprising:
- (a) a reel assembly adapted for affixation to a hub of a worn drive tumbler wherein said hub and a portion of a plurality of radial gussets support said reel assembly for engagement with said pad drive;
- and
- (b) a plurality of wear members detachably secured within a plurality of angularly spaced apertures defined by said reel assembly.
A method of refurbishing a drive tumbler comprising the steps of:
- (a) reducing the diameter of said drive tumbler by removing from the periphery thereof substantially all of the material exhibiting wear thereto;
- (b) affixing to said tumbler a plurality of radially extending gussets, partially replacing the removed material;
- (c) affixing to said gussets a reel member having a plurality of opposing outwardly facing seats formed therein, said seats being angularly spaced apart and said reel member being held in parallel spaced relation by said gussets;
- and
- (d) detachably affixing a plurality of wear members to said reel member, each wear member of said plurality being received in a pair of opposing seats in said reel member.
