Summary

Description
English: Engraving of the first ratcheting socket wrench and two sockets, invented by J. J. Richardson and patented on June 18, 1863, from the article about it in Scientific American magazine. Instead of a male connector on the wrench, as modern socket wrenches have, in this tool the outside of the sockets (E) fit into the square hole (F) in the wrench. The ratchet (C) only turns in one direction; to turn nuts in the other direction the wrench is turned over and the socket is attached to the other side. Alterations to image: removed caption "RICHARDSON'S PATENT WRENCH" and converted to 4 greyscale PNG.
