Many parts or assemblies used in business equipment must be accessed by either operators, service technicians, riggers, etc. These parts or assemblies must be moved in order to facilitate jam clearance, cleaning adding consumables etc. from their normal position to a temporary position. It is frequently desirable to ensure that these parts or assemblies remain in the temporary position without manual assistance while one performs one of the above-mentioned functions. A device that allows parts and assemblies to remain in a temporary position is shown the Figure in the form of a counterbalance apparatus 10. As shown in the Figure, a clutch housing 13 is supportably mounted on a shaft 11 with a one-way clutch positioned within the housing. A rotating housing 15 is mounted on shaft 11 adjacent one end of housing 13 and is backed up by a non-rotating disk 20 which is held in position by Belleville washerb) 17 that is compressed against the non-rotating disc by adjustable nut 19. An arm 30 extends from housing 30 for rotating the housing by hand.
