Description: |
| A spring-loaded central pin in the center of a ratchet driver has a indentation into which the spring ball or detent which holds a socket can retract.
The patent was the basis for SEARS, ROEBUCK & Co.'s quick release feature on CRAFTSMAN ratchets, and the center of protracted litigation between SEARS and the inventor.
