R.F. Sedgley "Hexall" hex-drive socket set Patent 1289558 Dec. 31, 1918
R.F. Sedgley, 2311 North Sixteenth Street, Philadelphia, Pennsylvania USA
Founder and inventor Reginald F. Sedgley apparently manufactured these as early as January 24, 1916, according to the November 25, 1916 "Hardware Age" magazine advertisement and the patent document for his "Hexall" trademark.
Best known for their line of "Hexall" sockets, Sedgley also manufactured other tools (photos of which can be found at Alloy-Artifacts.org. and in a couple other threads on this site.)

This 1/4" hex drive SAE socket set includes seven plain steel sockets, none of which have any markings, and an "ELL" wrench, which is marked only with the patent date of Dec. 31, 1918.


The sizes on the six-point sockets are 1/4", 5/16", 11/32", 3/8", 7/16", 1/2", and the round knurled socket.
Similar sets were later manufactured by other tool makers, among them New Britain Machine Co., Duro Metal Products Co., and Indestro Mfg. Corp., as well as several offshore tool makers (presumably Japanese.)
