- For general vise and fixture use. A press on the locking
lever actuates the eccentric crank which tilts
- the locking ring, thereby
gripping the entire circumference of the center bar, forcibly moving the
jaw
- forward against the workpiece. Raising the locking lever to vertical
position permits the spring to return
- the locking ring to neutral position,
allowing the jaw to slide back, releasing the workpiece. Adjusting
- screw,
locked by cover plate, controls amount of pressure.
- "PA" Series Locking Mechanism,
- with Pumping Action
- Operator is able to advance the jaw forward by "pumping"
the locking lever, thereby "taking up" on compressible
- materials
such as warped castings, wood or metal laminations, plastics, etc. The
addition of a holding ring holds the jaw
- against work with 200-350 pounds
of pressure while the locking lever is at a 60-80 degree angle.
- The holding
spring returns the holding ring to neutral position.
