Abstract:
1. In a fragmenting rotor assembly for waste wood and other fragmentable material: a. a drive shaft and mechanism for driving said shaft in a direction of rotation, said drive shaft incorporating axially spaced radially projecting rotors along its axis; b. a series of radially projecting side for side reversible hammer mounting hammer supports selectively situated along the axis of said shaft on said rotors and powered by said shaft, the hammer supports having radially outward heads with a rotatively leading face portion and a parallel trailing face portion adapted to selectively mount said hammers radially outward of said rotors; c. said hammers comprising fragmenting knives removably secured to the rotatively leading portions of said hammer supports; d. said knives having axially extending reducing edges; and e. said hammer supports being mounted at the sides of said rotors to partly overlie said rotors axially to define axially abutting adequate radial support for paths of knife travel.
