Abstract
A tiltable table has a pneumatic actuator and a locking system for establishing and maintaining a table position. The locking system is operated by an air cylinder that engages a dog with a ratchet plate secured to the table. The dog is spring-biased to locking position, and is air-operated for release against the action of the biasing spring. On lowering the table, air is permitted to escape through a restriction orifice at a slow enough rate to maintain sufficient air pressure to keep the locking system disengaged, but sudden release of all the air pressure will again permit the spring to re-lock the system to prevent a downward slamming of the table surface.
