c NI'IED'STATES EDMOND BOY, OF NEW YORK, N. Y.
IMPROVEMENT IN ELECTROPLATlNG-BATHS.
Specification forming part of Letters Patent No. 155,700, dated October 6, 1874; application filed July 3, 1874.
- the following is a specification:
The object of this invention is to produce a peculiar plating solution, from which will be deposited a metallic alloy of great beauty for the ornamentation of articles of copper, iron, brass, or other metals or alloys.
I make a solution of arsenic, using pure or distilled water-about two hundred parts, by weight, of water, and twenty parts of powdered arsenic. The water is to be heated to dissolve the arsenic. I add to the foregoing twenty parts of cyanide of potassium, and allow the liquid to remain until it is clear. I take about one part of sulphate of copper, one part of sulphate of zinc, and four parts of carbonate of soda, and grind them together, and diss'olr e them in water, and mix the same with the solution before named, and the liquid is' thoroughly stirred and allowed to subside. A small quantity of cyanide of potassium may also be required to perfect the solution.
The solution is washed and filtered to remove any impurities and prepare the solution for use in the plating-bath.
This solution is placed in an iron or porcelain lined or other bath, and kept in a boiling condition by steam or fire heat. The article to be plated is suspended in the solution, and
the negative pole of a galvanic battery is connected thereto. The positive pole terminates in a strip of platina or other metal placed in the solution contiguous to the article to be plated.
A rather strong current is required to perform the plating, and the article should be clean and polished previous to immersion in the solution. With copper it is best toclean it with muriat-ic acid and brown it with sulphuric acid.
The plating,with this alloy, is of a lustrous bronze color and highly ornamental. It may be cleaned from time to time, or it may be pro tected with lacquer.
I claim as my invention The bath for electroplating, prepared of the materials and in the manner specified, for depositing the metallic alloy set forth. r
Signed by me this 29th day of June, A. D. 187 4.
EDMOND. BOY.
