Description:
The patent describes a linkage in the frame which provides sufficient movement for the jaws to grip and release pipe. There are three pins and a slot in the linkage. The drawing shows the patent applied to a combination pipe and nut wrench.

The corresponding wrench has four rivits, and no slot. This makes the frame relatively solid, with no provision for the grip and release movement. The jaws have pipe gripping teeth. The wrench is marked UNCLE TOM WRENCH on the head, and PAT APL 26-12 on the threaded shank.
