Abstract: An improved cover lock apparatus comprises a rotatable and axially slidable crank plate connected to a plurality of retractable lock rods. The crank plate is disposed between the cover and a lock plate and is slidably and rotatably mounted to the lock plate. The crank plate has two upwardly protruding lock pins oriented to engage mating holes in the lock plate and is upwardly biased against the lock plate by a spring. When the lock pins are engaged in these holes, the crank plate cannot be rotated to retract the lock rods. Before the crank plate can be rotated to retract the lock rods, the lock pins must be disengaged from the mating holes in the lock plate by forcibly pushing down on the crank plate via a special lock key to overcome the spring bias that normally holds the crank plate pins in the engaged position. Once the crank plate is pushed downward enough to disengage the lock pins, it can be rotated to retract the lock rods.

Abstract: A stripper for separating a print substrate from a fuser member in an electrostatographic printing machine has a substantially flat, thin, resiliently flexible finger-like member having a raised dimple-like bump adjacent one end of the finger-like member for contacting the print substrate when stripped from the fuser member, the finger-like member being coated on both sides with a smooth low surface energy film.

Abstract: An endless belt driven wood lathe or the like is disclosed as having an endless belt tension adjustment device for a motor driven belt pulley and associated endless belt. The belt pulley is driven by a generally horizontal shaft extending from a motor that is pivotally mounted to a motor housing. The motor is pivotally mounted to the motor housing along a shaft that is generally parallel to the motor shaft about which the belt pulley is journalled. An endless belt adjustment device is connected to the motor through adjustable slot means in the motor housing to cause the motor to be pivoted relative to the motor housing while predetermined spring tension force is applied to the motor, including the motor shaft journalled belt pulley and endless belt entrained thereabout. The belt pulley preferably includes a series of stepped pulley sections each having an outer surface which is configured to engage a poly-V endless belt in a compact and efficient construction.
