Description:
This patent covers a new type of construction for "Continental-pattern" double gages of the type favored by the German and Dutch carpenters.

This gage uses a metal shell covering a thin wood head, and using the double-wedge locking system common to these type of gages. This construction would be very strudy and cheap to produce.
