Patent ID: 8256700

Claim:
A dispenser for dispensing a continuous feed material, said dispenser comprising: a housing; a first gear mounted in said housing, said first gear being rotatable about a first axis; a chassis movably connected to said housing; a second gear mounted on said chassis, said second gear being rotatable about a second axis that is parallel to said first axis; wherein teeth of said first gear and teeth of said second gear are configured to intermesh with each other and to allow continuous feed material to pass therethrough, said chassis being configured to maintain said first and second gears adjacent to each other while enabling a distance between said first and second gears to be adjustable; and a brake connected to one of said first and second gears that controls an amount of force required to rotate said one of said first and second gears, the brake comprising a resilient member mounted on an axle of said first gear and a screw threaded into said axle of said first gear, wherein loosening and tightening of said screw varies compression forces on the resilient member so as to adjust an amount of force required to rotate the first gear.
