page_text: LETTERS PATENT to Jean François Chevalier, of Lyons, France,
for the Invention of "A NEW LIQUID POLISH FOR CLEANSING AND BRIGHT-
THING Dia VARVESTED
AND MA
"
Sealed the 6th March 1874, and dated the 26th September 1873.
PROVISIONAL SPECIFICATION left by the said Jean François Chevalier
at the Office of the Commissioners of Patents, with his Petition,
on the 26th September 1873.
I, JEAN FRANÇOIS CHEVALIER, of Lyons, France, do hereby declare
the nature of the said Invention for "A NEW LIQUID POLISH FOR CLEANSING
AND BRIGHTENING PAINTED, VARNISHED, GLAZED, AND METALLIC SURFACES," to
be as follows:-
My Invention relates to the preparation and application of a liquid for
cleaning and polishing pictures, painted and varnished articles, metals,
glazed and varnished fabrics. The preparation of this liquid is effected
in three stages as follows:-
First. To prepare 22 gallons of the liquid. 22 gallons of water are.

page_text: poured into a trough, to this are added 36 pounds of hydrochloric acid,
and the same weight of alumino-calcareous earth, preferably that found
in the mine of Rosières in the French department of Haute Loire.
The mixture is allowed to stand a day while the carbonic acid is
disengaged.
Secondly. Ivory black in cake to the amount of 15½ pounds is
pulverised and strewn over the liquid resulting from the first operation.
It is again allowed to stand a day.
Thirdly. The mixture is now stirred until the carbonic acid is
thoroughly disengaged, it is then left to settle, and after the third day
the liquid is carefully filtered off.
The proportions may be somewhat varied from those stated above, and
the aluminous and calcarcous ingredients may-be obtained from other
minerals or calcined bones. Also glycerine and colouring matters may
be added.
In applying the liquid prepared in the manner set forth to varnished
articles, such as carriage panels, furniture, or wall surfaces or to metals,
as to mouldings and mountings, to lamps and reflectors, to paintings and
other objects, the surface is first moistened with the liquid applied by a
sponge or cloth and allowed to stand about two minutes till the cloudy
coating or tarnish becomes decomposed. The surface is then rubbed
with a brush or woollen cloth till the tarnish is removed, farther moisten-
ing with the liquid being resorted to if the tarnish should be thick or
difficult of removal. The surface is then washed with water applied by
another sponge or cloth and allowed to dry till it presents a dull appear-
ance resulting from the presence of the material which constitutes
the polish. It is then rubbed with chamois leather till the polish is
brought up.
With the exception of articles gilded with leaf, fresco paintings, and
iron surfaces, which should not be treated with this material, almost
all other articles of furnature, ornament, or decoration susceptible of
polish can be cleaned and brightened by its use in the manner described
above.
