COMPLETE SPECIFICATION.
Improved Polishing Cream.
;
We, CARL SCHMIDT, and EMIL LOH, Proprietors of the firm of August Loh
Söhne, Army Contractors, of 22 Wilhelm Strasse, Berlin Germany, do hereby
declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:
The present invention consists of a cream for polishing metallic surfaces.
The creams, paste, and the like for polishing metallic surfaces up till now in use,
possess many faults for instance many smear the surface when brought into contact
with the same, all contain more or less poisonous ingredients, very many contain
emery powder which scratches the surface of the metal or they contain a certain
quantity of acid which is very injurious to the said metallic surface.
Particularly the red polishing pastes, which have been much in employment
hitherto, have the great disadvantage that after having been in use a certain time
they discolor the metal entirely. This is due to the fact that every metal is, to a
more or less extent, porous, and particles of the red paste set in the said pores, so
that after a certain time the metal surface gradually begins to assume a red or
reddish brown tinge, which entirely destroys its good appearance.
The object of the present invention is to produce a polishing cream having none
of these disadvantages and the inventors have found that a cream composed of the
following ingredients, attains this purpose :-
1: It does not smear or smudge the surface on which it is rubbed.
2: It contains no poison and is consequently of particular advantage for
household use.
3-lt is white and does not therefore discolor the metal in any way, as is the
case with the red polishing paste.
4-It contains no emery and consequently cannot scratch or mar the surface of
the metal.
5 It contains no acid.
In order to carry our invention into practice, the ingredients are mixed in about
the following proportions :-
Stearine oil
White tripoli
Ceresine
Oil (mineral)
54-74%
36.50°
7.30%
1.46%
The ingredients are mixed, melted down together and stirred, and allowed to cool
down to a thick cream.
The proportions may be slightly varied if so desired for different purposes.
Metallic surfaces, cleaned by means of this cream receive a bright and durable
polish, will never be discolored, and will not be scratched or marred in any way.
Instead of stearine oil, oleine may be employed, the effect being the same.
As this cream contains neither acid nor emery it may be used for polishing the
softest metals, whilst the fact of its containing no poisonous ingredients renders its
adoption for household use most advantageous and desirable.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is performed, we declare that what we
claim is :-
1 A polishing cream consisting of the combination of stearine oil, white tripoli,
ceresine and mineral oil melted down together in, the specified proportions and
allowed to cool down to a thick cream substantially as described and for the purpose
specified.
2-In the composition of the polishing cream covered by Claim 1, the substitution
of oleine for the stearine oil substantially as specified.
