dip Stlirtnlt man?! in in time Eaters patent ma muting part at tlge time."
TO ALL WHOM IT MAY CONCERN:
Be it known that we, ACIIILLE Scmuxrrn and HrLAmnANnni: LEVALLOIS, of Paris, France, manufacturers,
have invented New Alloys, so-cal led Mock-Silver," (minargent,) composed of difl'erent metals, and applications thereof; and we do hereby declare that the following is a full, clear, and exact description of the same.
Our invention consists in certain alloys composed of diflerent metals, which alloys we designate by the name of mock-silver, (minargent,) and in the various applications of the same. 'Thisso-called mock-silver may be compared to silver at .900 standard on account of its whiteness, malleability, ductility, tenacity, sonority, and density; it is even of a superior brightness, notso liable to wear, withstands in agrater measure the emanations of sulphured hydrogen, and is less fusible. w
The mock-silver (minargent) is fitted to receive all the applications of not only silver, but also of any white metal and alloy. It is composed as follows: Unalloyed copper, one thousand parts; unall oyed nickel, seven hundred parts; unalloycd tungsten, fifty parts; unalloyed aluminum, ten parts. But we do not confine ourselves to the exact above proportions, which may vary, and are only given here as a mere specimen and type. of
our invention.
-What more particularly characterizes our mock-silver, is introducing unalloyed tungsten and unalloyed aluminum among its constitutive alloys, and the-above considerable proportion of nickel, the anti-aifinity of which for aluminum is well known, and which we have made alloyable. We do therefore claim not only the above typic proportions, but any proportions which in practice will answer the purpose.
We will actually describe thenoperation: We first melt togethe r the first three elements, having care to cover them with some lumps of coal. We cast them in small shots, which we melt again afterwards, adding thereto the above-mentioned proportion of aluminum and one-half per cent. 'of a flux composed of one part of borax and one of calcic fluoride, which proportions of said flux may diminish when the fusions are more considerable. As to the casting into ingots or moulding in sand, these operations take place in the usual way, care being taken that the material shall keep remounting, or in half ascent at lea be smeared with some fatty bodies, such as tallow or common rosin. The forging, rolling, drawing into wires, and annealing are efiected by the usual and known methods, avoiding, however, to use sulphurous-fuel. As to the whitening of the material, we eifect it by means of diluted sulphuric acid, a-nd the tarnish is removed by means of nitric acid, as-sold by trade.
Claims.
1. The new alloy so-called mock-silver, (minargent,) composed of different metals, as described.
2. Introducing in our so-called moclrsilver unalloyed tungsten, unalloyed aluminum, and a considerable proportion of nickel, the anti-afiinity of which for aluminum is well known, and which we have made alloyable.
3. And we claim not only the above-mentioned typic proportions, but also any proportions which will answer the purposes.

LEVALLOIS.
