Stan Schulz FRANK MOSSBERG Co. Catalog No. 12 (archive.org)
|
Description: |
The patent mentions the sockets, universal joint, and rod handle shown in the drawings. The key item in the patent is the unique spring-loaded "slip-clutch" ratchet section.
The Frank Mossberg Co. took over U.S. production in 1909, and made the Auto-Cle the center of an extensive line of socket sets. A 1910 Frank Mossberg Co. digitized in archive.org provides details of these sets.
Contals' Nov. 7, 1916 "Extensible Tool" patent (no. 1,203,853) is based on the AUTO-CLE. |
