This is a fairly simple and useful design, covering a slotted bar with an adjustable mortise point, and an unusual head retaining mechanism. Of interest in this design is that the adjustable point is the outbound point-- almost all other designs have the outbound point fixed.

The head locking mechanism is also quite clever, using tension on a collar around the bar to hold it in place. This would hold quite firmly without marring the bar.
