Description:
Most of the specifications are a detailed discussion of the relationship between the pitch of the cam, its ability to hold the adjustment, the size of the center pivot bolt, and the range of jaw settings. A friction spring holds the cam's adjustment against incidental movement.

The cam-adjust nut wrench marked *CHARLES RICHARDS & SONS LTD. DARLSTON, ENGLAND // BURSTON 1-26-32 BRITISH PAT 384468* closely resembles this patent.
