Screw Eye: Parmelee's One-Piece Wire Eye with a Stop-Ring
A screw eye bent from one piece of wire, by Arthur W. Parmelee of Worcester, Massachusetts (US 350,209, 1886). One end is threaded to turn into wood, the other bent into a closed eye. His addition is a ring closed into a groove around the shank: it stops the screw at the right depth, looks neat, and is left a little loose so the eye can turn without marking the wood under it.
The patent gives no metal or sizes. Iron wire, the 3 mm size, the pliers and the die are ours. The picture: Figs. 1-3 and 10-11 of the patent.
