  • Stamper having adjustable die depth
    Patent number: 5115729
    Abstract: A pre-inked stamper has an adjustable die depth to accommodate shrinkage and to vary die impression. Adjustment is accomplished by rotation of a handle about a shaft which is attached to the die to thereby alter the stroke. A ratchet and pawl mechanism includes a plurality of grooves having camming surfaces formed on an end of the shaft located adjacent the handle. A pawl selectively engages the grooves and biases the handle against unintended rotation.
