Turret Gun Mounting Christie Gledhill and Carington Original Patent Lithograph 1888
On this original linen-backed lithograph from 1888, R. C. Christie, M. Gledhill and H. H. S. Carington patented a turret gun mounting that facilitates the working of guns mounted on minimum embrasure carriages. The gun, with its carriage and slides, is vertically adjusted about a virtual pivot in or near the center of the embrasure. Two guns may be mounted side by side, and the elevating gear connected so that the weights balance each other, on gun rising while the other falls. Hydraulic elevating-cylinders may also be provided beneath the slides.
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.
