Report data errors or omissions to steward Russ Allen.
Description:
Made out of flat stock with a "T" and two series of graduated shoulders running diagonally with provisions to receive a pencil or handle at the end rather than the earlier Lufkin style with a finger hole. Strangely, the patent drawing's first two figures show the type of gage this patent is intended to improve upon rather than the item to be patented.
