UNITED STATES PATENT Enron.
FRANK J. BLAIN, OF CINCINNATI, OHIO, AND EVERETT RARDON, OF NEW- PORT, KENTUCKY.
PROCESS OF PREVENTING TARNISHING IN SILVER-WARE.
SPECIFICATION forming part of Letters Patent No. 312,954, dated February 24, 1885.
Application filed May 10, 1884. (No specimens.)
To all whom it may concern:
Be it known that we, FRANK J. BLAIN and EvERETr RARDON, both citizens of the United States, the former residing at Cincinnati, in
the county of Hamilton and State of Ohio, and the latter residing at Newport, in the county of Campbell and State of Kentucky, have invented certain new and useful Improvements in Paper and other \Vrapping Process for Preventing Tarnishing, of which the following is a specification.
The object of our invention is to prevent metals from becoming tarnished ordiscolored by the action of snlphureted hydrogen gas,
1 which floats in the atmosphere.
llIanufaeturers and dealers in solid and plated wares experience great difiiculty, especially with silver and brass wares, from the metals turning black or becoming tarnished by the action of sulphureted hydrogen gas floating in the atmosphere. Bronze and brass metals also tarnish from the same cause. XVe have discovered a remedy for this difficulty. It consists, first, in providing a wrapping for the metal wares dipped in a solution of metal salts, which metals have a greater aifinity for the sulphureted-hydrogen gas than the metals to be preserved.
The preferred plan of employing our-invention is as follows: Take fine tissue-paper and dip it in asolution of acetate of lead dissolved in water. One dram of lead to one ounce of water is the qjreferred strength of solution. Then the paper is dried, when it may be 3 5 wrapped around the wares or goods to be preserved. The sulphureted-hydrogen gas is absorbed or unites with the salts of lead, and does not attack the finer metals to which the wrapping is applied. After a long period of time, however, the paper turns black, and a new wrapping is of course required.
Instead of using paper, any other fibrous wrapping material-such as papcnmuslinmay be employed but the tissue-paper is the cheapest and best.
If the wares are desired to be kept exposed in a cabinet or closed case or upon a sideboard, large rolls, bales, or bundles of the paper treated in the solution of salts may be placed in close proximity to the metal. Or thin paper-muslin may be treated with the solution and used as a lining for the shelves or cabinet-case surrounding, butat some little distance from the wares.
The affinity of the salts for the sulphureted- V hydrogen gas is so great that it will be attracted by the salts upon the surface of the preserving material, and will not unite with the finer metal. By this means we avoid the use of all alkalies and chlorines, which are apt to deleteriously affect the silver. The acetates of lead, when dissolved and absorbed by fibrous material, will neutralize not only hydro-sulphuric gases,but ph sphoric and other similar gases, which pervade the atmosphere in towns and cities. These acetates are much more durable than chloride and alkaline salts hitherto employed for this purpose, and we disclaim the use of such preparations.
What we claim is- The herein-described process of preserving silver from tarnishing,which consists in wrapping or surrounding the wares with fibrous material impregnated with a solution of the acetates of lead dissolved in water, substan- 75 tially as herein specified.
In testimony whereof we have hereunto set our hands.
FRANK J. BLAIN. EVERETT RARDON.
