Brush chipper assembly with counter-rotating feeder rollers and actuating chipping heads

A brush chipper assembly comprising:

• a housing;
• a feeder subassembly connected to the housing;
• the feeder subassembly including opposed, first and second feeder rollers;
• when the feeder subassembly is actuated, the first feeder roller is operable to rotate in a first direction and the second feeder roller is operable to rotate in a second direction so as to draw feedstock to be chipped into the housing;
• the first direction being opposite to the second direction;
• whereby the first and second feeder rollers are biased in respective first positions;
• when the feeder subassembly is actuated, the first and second feeder rollers being capable of being actuated to second respective positions, thereby adjusting the size of a gap defined by outer boundaries of the first and second feeder rollers;
• a chipping subassembly substantially contained within the housing behind the feeder subassembly;
• the chipping subassembly including first and second, opposed chipping heads and a drive assembly for driving rotation of the first and second chipping heads;
• each chipping head carrying a plurality of cutting teeth for chipping the feedstock fed into the brush chipper assembly;
• whereby the first and second chipping heads are biased in respective first positions;
• when the chipping subassembly is actuated, the first and second chipping heads are capable of being actuated to second respective positions, thereby adjusting the size of a gap defined by outer boundaries of the first and second chipping heads for allowing the chipping subassembly to accept feedstock with a diameter exceeding the diameter of the first and second chipping heads;
• and whereby the chipping subassembly is actuated, the first chipping head is operable to rotate in a third direction and the second chipping head is operable to rotate in a fourth direction;
• the third direction being opposite to the fourth direction and the first direction;
• the fourth direction being opposite to the second direction.

A method of chipping brush, comprising the steps of:

• providing a housing;
• providing a feeder subassembly connected to the housing;
• the feeder subassembly including opposed, first and second feeder rollers;
• when the feeder subassembly is actuated, the first feeder roller is operable to rotate in a first direction and the second feeder roller is operable to rotate in a second direction so as to draw the brush to be Chipped into the housing in a horizontal direction;
• the first direction being opposite to the second direction;
• providing a chipping subassembly substantially contained within the housing behind the feeder subassembly so that said feedstock is fed by said feeder subassembly directly into said chipping subassembly in said horizontal direction;
• the chipping subassembly including first and second, opposed chipping heads and a drive assembly for driving rotation of the first and second chipping heads;
• each chipping head carrying a plurality of cutting teeth for chipping the brush fed into the brush chipper assembly;
• when the chipping subassembly is actuated, the first chipping head is operable to rotate in a third direction and the second chipping head is operable to rotate in a fourth direction;
• the third direction being opposite to the fourth direction and the first direction;
• the fourth direction being opposite to the second direction;
• rotating the first feeder roller in a first direction and rotating the second feeder roller in a second direction;
• the first direction being opposite to the second direction;
• rotating the first chipping head in a third direction and the second chipping in a fourth direction;
• the third direction being opposite to the fourth direction and the first direction;
• the fourth direction being opposite to the second direction;
• feeding feedstock into the brush chipper assembly;
• and
• splitting the inner portion of the feedstock from the inside of the feedstock toward the outside of the feedstock, as the feedstock is urged deeper into the chipping subassembly.
