I'ROVISIONAL SPECIFICATION.
A New or Improved Alloy.
I, ALEXANDER MELVILLE CLARK, of the firm of A. M. and Wm. Clark, of
53, Chancery Lane, in the County of Middlesex, Follow of the Institute of Patent
Agents, do hereby declare the nature of this Invention a communication to me from
abroad by La Société en participation Bourbouze et Compagnie of 340 Rue Saint
Jacques, Paris, France to be as follows:-
This invention consists in the production of a new metal or alloy constituted by
the combination of aluminium and tin in the combining proportions of one hundred
parts of aluminium and ten parts of tin.
No special processes or furnaces are needed for the production of this new metal or
alloy, the furnaces and crucibles ordinarily employed in metallurgy being available.
The density of this new alloy is 2.85 and its index of specific heat is 0.180. It
possesses in the highest degree the characteristic propertics of pure alupiinium vz.,
strength, lightness, inoxidability, ductility &c.
If by accident an excess of tin should be added at the time of fusion the true
nature of the alloy would not be affected as in no case would a larger proportion of
tin than that indicated enter into combination, the tin in excess would merely remain
in admixture with the metal or alloy from which it would be expelled immediately
the alloy is subjected to the operation of rolling.

COMPLETE SPECIFICATION.
A New or Improved Alloy.
1, ALEXANDER MELVILLE CLARK, of the firm of A. M. and Wm. Clark, of
53, Chancery Lane, in the County of Middlesex, Fellow of the Institute of Patent
Agents, do hereby declare the nature of this invention (a communication to me
from abroad by La Société en participation Bourbouze et Compagnie, of 340, Rue
Saint Jacques, Paris, France,) and in what manner the same is to be performed, to
be particularly described and ascertained in and by the following statement :-
This Invention consists in the production of a new alloy constituted by the com-
bination of aluminium and tin in the combining proportions of one hundred parts of
aluminium and ten parts of tin.
No special processes or furnaces are needed for the production of this new alloy, the
furnaces and crucibles ordinarily employed in metallurgy being available.
The density of this new alloy is 2-85 and its index of specific heat is 0.180. It
possesses in an eminent degree the characteristic properties of pure aluminium, viz.
strength, lightness, inoxidability, ductility, etc.
If, by accident, an excess of tin should be added at the time of fusion, the true
nature of the alloy would not be affected, as in no case would a larger proportion
of tin than that indicated enter into combination; the tin in excess would merely
remain in admixture with the alloy from which it would be expelled immediately the
alloy is subjected to the operation of rolling.

page_text: Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, I declare that what I
claim is ;-
The manufacture of the herein described new alloy composed of one hundred parts
of aluminium to ten parts of tin, the density of said alloy being 2.85 and its index of 5
specific heat 0.180, as specified.
Dated this 2nd day of January 1.
