Description: |
| The focus of this patent is the two-stage movement during release of the lock. This two-stage movement is effected by the sliding connection between the adjustable link and the main lever handle. The same feature is shown in Patrick's parallel patent (no. 3,545,315), and appears on the CHANNELLOCK No. 910 GRIP-LOCK pliers.
The specifications cite patent nos. 2,853,910 and 2,997,903 as references. |
