Abstract
Abstract A forage blower having a recutter coaxial with an impeller mounted within a common housing. Material is entered axially into a cylindrical foraminous cage of the recutter and is sheared by blades of a chopper rotatable within the cage. The cut material is thrown circumferentially and radially out of the cage into the impeller paddles which sweep the recut material into an outlet.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
99 words
A material blower-recutter comprising a housing having a generally cylindrical peripheral wall with an outlet opening and axially spaced side walls interconnected with the peripheral wall, an impeller journaled between said side walls and having paddles about its periphery sweeping said peripheral wall, an open ended generally cylindrical recutter means between said walls and concentric with said impeller, said recutter means comprising a foraminous cage positioned concentric with the axis of said impeller in axial alignment with the inlet and having an impervious segment adjacent to the outlet opening to prevent material from being discharged across the outlet opening.
Claim 2
Dependent Claim
99 words
A material blower-recutter comprising a housing having a generally cylindrical peripheral wall with an outlet opening and axially spaced side walls interconnected with the peripheral wall, an impeller journaled between said side walls and having paddles about its periphery sweeping said peripheral wall, an open ended generally cylindrical recutter means between said walls and concentric with said impeller, said recutter means comprising a foraminous cage positioned concentric with the axis of said impeller in axial alignment with the inlet and having an impervious segment adjacent to the outlet opening to prevent material from being discharged across the outlet opening.
Claim 3
Dependent Claim
158 words
A material blower-recutter comprising a housing having a generally cylindrical peripheral wall with an outlet opening, axially spaced side walls interconnected with The peripheral wall, and a generally axial material inlet opening in one of said side walls, a cylindrical perforated screen mounted on said one of said side walls within said housing and concentric with said peripheral wall, a rotor journaled along the axis of said housing and having cutting blade means operatively disposed in shearing relationship with said screen, and an impeller disposed coaxially with said rotor, said impeller having paddle means disposed between said screen and said housing, said rotor and said screen projecting axially beyond said peripheral wall of the housing, a frusto-conical housing portion on said one of side walls enclosing the portions of the rotor and screen outside the peripheral wall and providing a sloping slide surface toward said peripheral wall for material cut by said rotor and passing through the screen.
Claim 4
Dependent Claim
