Description: |
| Claim 1: "A ratchet wrench comprising: a ratchet head including a ratchet system for rotating a shank about an axis; a handle; a pin connecting said ratchet head and said handle, said connecting pin being aligned along an axis which is substantially parallel to the shank axis; said connecting pin extending through an orifice in one of said ratchet head and said handle, said one having said orifice being slidable between a locked position and an unlocked position on said connecting pin; in said unlocked position, said orifice being disposed about a portion of said connecting pin which is shaped to allow said one having said orifice to rotate about said connecting pin axis; and in said locked position, said orifice being disposed about a portion of said connecting pin which is shaped to engage said one having said orifice to prevent rotation thereof about said connecting pin axis."
Postings in a "Garage Journal" thread noted Cole produced this design under "SUPERIOR TOOL COMPANY" and "SUPEIOR RATCHET AND TOOL CO.}, and licensed the design (along with 5,775,184) to Snap-On.
