Description:
The handle section has a box wrench at one end and a pin at the other. The additional flat wrench pieces are double-ended, with a slot running a portion of their length, and paired hook-shaped projections on one side. A clamping bolt of some type holds the set together; the one described and shown in the patent has a cam-action.

In use, the selected wrench piece is slid out of the stack sufficiently to engage the hook around the pin.
