Abstract:
In a generally horizontal wood material comminuting machine comprising:a. a generally longitudinally disposed frame with front and rear ends and spaced apart side walls; b. a crosswisely extending rotatably mounted rotor shaft on said frame mounting a rotor having a periphery comprising comminuting members moving in a path of rotation; c. a crosswisely extending anvil carried on said frame above said rotor shaft outwardly of said periphery to coact with said comminuting members in reducing said material; d. a feed works connected with said frame forwardly of said rotor including a material support surface on which said material is supported and a powerdriven feed member having a generally horizontal axis extending generally parallel to said rotor axis mounted above said support surface for feeding said material toward said rotor; e. a drive for moving said rotor shaft and rotor in an uphill path of rotation upwardly relative to said material support surface; and f. lift arms pivoted on said frame rearwardly of said feed member pivotally carrying said feed member for swinging vertical movement toward and away from said material support surface; the improvement comprising in combination: g. a material deflector plate carried on said frame independently of said lift arms to substantially crosswisely span said rotor extending from a forward edge rearwardly toward said anvil to deflect material comminuted by said comminuting members traveling in said uphill path of rotation toward said anvil; and h. a crosswisely disposed lift arm plate, carried on said arms to move relatively upwardly and downwardly with respect to said deflector plate, having a downwardly curving surface coacting with said deflector plate to prevent fragmented material from flying past said forward edge of said deflector plate.
