and other Metals.'
I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake, Co., Patent Agents,
Southampton Buildings, in the County of Middlesex, do hereby declare the nature
of this invention to be as follows:
-
This invention relates to an improved composition designed to polish and renovate
copper or other metals and to the method of applying the same.
The proportions of the various substances of which my composition consists can
vary considerably, I have however, found the following to give excellent results
viz:-
130 to 150 grams of Venitian tripoli; which can be substituted wholly or in part
by rotten-stone or the like.
4 to 6 grams of brown red or peroxide of iron or other colouring matter not
attacking the metal; the said colouring matter being intended only to affect the
appearance of the product, and not its qualities.
75 to 100 grams of oxalic acid serving as a mordant; the oxalic acid being in
some cases wholly or in part replaced by bioxalate of potash.
0.140 litres of oleine, for transforming the substance into a paste and producing
upon the copper or other metal the brilliancy necessary for obtaining a perfect
polish.
The paste obtained by mixing these substances is put in boxes of tinned sheet
iron, or in bottles, or other suitable receptacles for trade purposes, and can therefore
be transported with facility.
In applying this paste it is diluted with boiling water in the receptacle itself or in
any other suitable vessel. The article to be polished is rubbed with the liquid thus
obtained by means of a piece of wool, cloth, flannel, or the like, and in a short time a
very beautiful polish is attained.

foreign correspondent I declare that what I claim is
First. An improved composition designed for polishing and renovating copper
or other metals, consisting of a paste obtained by mixing in suitable proportions
venetian or other tripoli and olcine, with or without brown red or peroxide of iron,
and with or without oxalic acid substantially as described.
Second. The method of applying the above described composition which consists in
diluting it with boiling water and applying the liquid thus obtained by means of a
suitable piece of wool, cloth or the like upon the article to be polished, for the
purpose of imparting lustre thereto as above described.
