Original linen-backed patent lithograph for an improvement in electric safety fuses by the Edison & Swan United Electric Light Co., one page, 13.5 x 10, October 26, 1895. The fuse wire is fitted on a holder so that it may be readily removed, and clamped to contact plates by a pair of nuts. The base carries notched contacts into which the contact pieces are dropped. The top border reads: "A.D. 1895. Oct. 26. No. 20,237. The Edison & Swan United Electric Light Co,. [Ld.] & another's Complete Specification." The lower border features the printed text: "London. Printed by Darling and Son Ld. for Her Majesty's Stationery Office. 1896" and "Malby & Sons, Photo-Litho." The right border reads: "This Drawing is a reproduction of the Original on a reduced scale." In fine condition. Formed by merger in 1883, the Edison and Swan Electric Light Company combined the incandescent lamp bulb manufacturers founded by Thomas Edison and Joseph Swan in order to avoid litigation over patent infringement.
