In 1893, H. P. Ranger was granted Patent No. 505,127 for a “Mirror For Use In Photography.” This was a device comprised of two adjustable mirrors set at an angle. When a subject was placed in front of it, his or her image was reflected in each mirror and that reflection was again reflected, resulting in five or more figures—the number of figures determined by the angle of the mirrors.
The above schema is from an article published in Scientific American in the 1890s that was included in the 1896 book Photographic Amusements by Frank R. Fraprie and Walter E. Woodbury. My husband and I own a copy of the 1931 edition that still contains the original illustrations.
Also from the book is the illustration above: “Diagram Showing The Method Of Production Of Five Views of One Subject By Multiphotography.”
