QELECTROTYPE PLATE Filed larch 11111 24 Patented July 7, 1 925. 7 I V UNITED STATES HENRY A. IBZEl-tli. OF CHICAGO, ILLINOIS.
ELECTROTYPE PLATE.
Application filed March 17, 1924. Serial R 899,794.
To all whom it. may concern: U Be it'known'that I, HENRY A. Hnnn, a citizen of the United States, residing at Chicago, in the county of Cook and State of- 5 Illinois, have invented certain new and use ful Improvements in Electrotype Plates, of which the following is a specification.
I In electrotype processes it is necessary to employ plates having a very hardsurface and for that reason electrotype plates are usually constructed of copper owing to the hardness of the material, with the result that a printing surface which isquite durable will be produced. These copper plates,- however, after a number of impressions have been takentherefrmri, wear out, oftentimes before the completion of the job, particularly if a great many'copies arev pulled or taken therefrom. It is one of the objects of the present invention to increase the life of a copper electrotype plate by increasing the hardness of the printing surface thereof. c
By actual test it has been found that the been treated in accordance with the present invention has been increased to such an extent that substantially five times as many more copies or impressions havebeen obtained therefrom than from the ordinary or usual copper faced electrotype plate which has not been .treated according to this inven- -with this invention, such attacks upon the plate are resisted and the life of the plate will be materially increased. Furthermore life of a plate of this character which has ployed but in practice a solution consisting of sixteen ounces of sulphate of iron; eight ounces of ammonia; one ounce of boric 4.- acid, to which is added a sufficient quantity of water to produce one' gallon of the solution, has been employed with eflicient result-s.
In use the copper plate isfirst cleaned and the iron solution. is then deposited upon the surface of the plate ,by any suitable and well-known electrolytic process, after which the plate will then be ready for use.
In practice it has been found that some of the inks contain certain chemicals and ingredients which attack or eat the copper of the plate,- but with a plate of this character having an iron coating thereon in accordance the cost of producing or treating a plate with this solution will'not be materially increased.
VVhat is claimed as new is 1. A copper electrotype plate having its printing surface coated with iron.
2. A copper electrotype plate having a deposit of iron upon its printing surface.
3. A'copper electrotype plate having an ironv printing surface.
4. The method of'preparing a copper electrotype plate by coating the printing surface thereof with a deposit of iron.
' 5. The method of preparing a copper faced electrotype plate by depositing iron upon the printing surface thereof by electrolytic process.
In testimony whereof I have signed my name to this specification, on this 14th day of March, A. D. .1924.
