Patent ID: 7891592

Claim:
A vibratory hopper and a shredder in combination, said combination being used for shredding paper material and comprising: a. a vibratory hopper for receiving said material to be shredded, said vibratory hopper having an open side that opens into a fixed hopper; b. said fixed hopper receiving said material from said vibratory hopper and being mounted on a frame of said shredder and being shaped to direct material from said vibratory hopper into said shredder; c. said vibratory hopper having at least one vibrator thereon, said vibratory hopper being supported by at least one vibration damper so that vibration of said vibratory hopper does not cause vibration of said fixed hopper; d. said open side of said vibratory hopper overlapping slightly said fixed hopper, said vibratory hopper being spaced slightly apart from said fixed hopper with openings therebetween being sufficiently filled with flexible barriers to substantially prevent paper from exiting through said openings without causing said fixed hopper to vibrate as said vibratory hopper vibrates.
