The ratchet head is connected to the frame by pivot connections. A lever link can "pinch" the side frame members against the ratchet head to hold its orientation. The end of the frame terminates in a tang for a brace chuck. Known example marked only "PAT APLD FOR," the assumption is they were made by the patentee.
