DESCRIPTION:

On this original linen-backed lithograph from 1898, Joshua Pusey, a citizen of the United States of America, patented improvements in wrenches. The improved wrench is composed of a combination of the following essential parts; a forward and rear jaw, a guide-stem connecting them upon which one of the jaws is adapted to slide and a handle between bifurcations of which the jaws are placed, and to which the front or outer jaw is pivoted; together with lugs or projections of the handle which are adapted to bear and slide against rear surfaces of the rear or inner jaw.

All patent lithographs sold by Maymont Group are 100% ORIGINAL.

These documents are NOT reproductions or posters (patent art).

These are the original lithographs found in books obtained from the Patent and Trademark Office directly.

 

In the 1800's and early 1900's, inventors would submit a detailed drawing of the invention and/or improvements to the patent and trademark office. Once received and if approved, the Patent office would then send a letter of confirmation to the inventor and begin to take that drawing and etch it into stone in order to create and print this linen-backed lithograph. These documents are the original hard copies that were created by the patent office's artists, and act as patent examiner reference material. With that being said, these are 100% original and are the only physical copies in existence.
