Abstract:
An improved braking roller apparatus mounted on a roller frame comprising:(a) a generally cylindrically shaped driving roller housing having circumferentially spaced-apart, longitudinally extending ear receiving grooves; and(b) a driven assembly telescopically receivable within said roller housing, said driven assembly comprising:(i) a shaft having first and second ends connected to the roller frame;(ii) a roller clutch assembly mounted on said shaft for free rotation in a first direction, but for impeded rotation in an opposite, second direction, said roller clutch assembly including a hub portion and a radially outwardly extending flange portion;(iii) a first rotor mounted on said hub portion, said first rotor having circumferentially spaced-apart ears receivable within said ear receiving grooves;(iv) a rotor friction disk mounted on said hub portion intermediate said first rotor and said flange portion of said roller clutch;(v) second and third friction disks mounted on said hub portion;(vi) a first shim mounted on said shaft intermediate said second and third friction disks;(vii) a second rotor rotatably mounted on said hub portion proximate said third friction disk; and(viii) biasing means mounted on said hub portion for urging said first, second and third friction disks toward said roller clutch.
