Description
Patented Dec. 29, 1931 VICTOR WYLDES, OF TORONTO, ONTARIO, CANADA ALLOY 1V0 Drawing.
The invention relates to the production of an alloy which simulates gold both in appearance and characteristics, and mainly consists of the hereinafter described manner of compounding.
The ingredients employed in this process are as follows:
Pure alcohol 1 ounce The proportions given above are those preferred; variations may of course be resorted to still within the spirit and scope of the invention. The tin content also may be replaced by some other metallic chemical equivalent, such as zinc. Dry yeast may be substituted for magnesia. The effect, however, of substituting zinc and dry yeast is that the resultant alloy is somewhat harder.
Tn carrying out this process, the'copper is first melted in a. crucible or. the like and heated to twelve hundred degrees centigrade, the other constitutents being added in the order set forth in the herein formula at an interval of two minutes between the addition of each ingredient. The massis mixed for minutes and then boiled for minutes, the crucible being covered during boiling. The resultant alloy is subsequently poured into a mould and allowed to air-cool for half an hour following which it is immersed in clean cold water.
It may be stated that the use of fullersearth serves the double purpose of making the ingredients cohere and for coacting with the borax in lightening the colour of the alloy; the borax, of course, constituting the principal bleaching agent. The magnesia both clarifies and refines'the compound. The white precipitate (ammoniated mercury) accelerates amalgamation. The alcohol is introduced by reason of its tendency to impart lustre to the alloy, but may be omitted whenever a high degree of brilliancy is not required. Tin, as well known, produces hard- Application filed December 5, 1929. Serial No. 411,991.
ness, whilst additionally it aids in lightening the colour of the alloy. However ,for this latter purpose other white metals might be resorted to.
According to this process and method of compounding, an exceedingly lustrous metal is produced simulative of gold. It not only possesses the same physical properties, such as malleability and ductility but is found to have an even more desirable characteristic in that like gold it is immune from tarnishing. The possession of the above characteristics and the fact that this simulative gold can be produced cco omically renders it admirably suited for substituting gold in the manufacture of jewelry, and extend its use to such articles as name-plates, hand-rails, door handles, and many other articles where the high cost of gold practically prohibits its use.
What I claim is:
1. A process of producing an alloy of the class described consisting in melting 5 lbs. 10 ozs. copper, successively adding 3 ozs. fullers-earth, 7 ozs. borax, 3 ozs. white precipitate, 12 ozs. tin, 3 ozs. magnesia, and agitating the mixture.
2. A process of producing an alloy of the class described consisting in {melting 5 lbs. 10 ozs. copper, successively adding 3 ozs. fullers-earth, 7 ozs. borax, 3 ozs. white precipitate, 12 ozs. tin, 3 ozs. magnesia, and 1 oz. alcohol, and mixing and boiling the mass.
3. A process of producing an alloy of the class described consisting in melting and heat- 8 ing 5 lbs. 10 ozs. copper to about twelve hundred degrees centigrade, adding successively at two minute intervals 3 ozs. fullers-earth, 7 ozs. borax, 3 ozs. white precipitate, 12 ozs. tin,
3 ozs. magnesia, and 1 oz. alcohol, mixing the resultant mass for about thirty-five minutes, and boiling it for about forty minutes.
Signed at Toronto, Ontario, Canada, this 25th day of November, 1929.
