the said Invention for "IMPROVED LIQUID STOVE POLISH," a communica-

page_text: .
To prepare the fluid stove polish we dissolve about one half pound
of alum in one-third of a gallon of water. Then take two and one half
pounds of plumbago, one pound of German black lead, and half a
pound of lampblack, and mix the same with about two-thirds of a
gallon of vinegar and half an ounce of essence of oil of almonds or
other extract, and then add the dissolved alum. These ingredients
must then be well mixed for about one hour, for which purpose we
prefer a closed cylinder provided with internal revolving projecting
flanches or arms; after which the mixture is ready to be filled in
bottles. This polish is applied with a sponge or hair brush to the
surface of the stove, and is then rubbed either with a polishing brush
or a woolen cloth till dry, and will produce a finer polish and last
longer than any other polish at present in use.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Robert Birch and William McGiffert in the Great
Seal Patent Office on the 20th April 1874.

.
-
The nature of this Invention consists in mixing plumbago, lamp-
black, and alum with vinegar, water, and essence of oil of almonds, or
other extract.
To prepare the fluid stove polish we dissolve about one half pound of
alum in one-third of a gallon of water, then take four pounds of
plumbago and half a pound of lampblack, and mix the same with
about two-thirds of a gallon of vinegar and a quarter of an ounce of
essence of oil of almonds, or other extract, and then add the dissolved
alum. These ingredients must then be well mixed for about one hour,
for which purpose we prefer a closed cylinder provided with internal
revolving projecting flanches or arms; after which the mixture is ready
to be filled in bottles. This polish is applied with a hair brush to the
surface of the stove, and when perfectly dry then rubbed with a
polishing brush, and will produce a finer polish and last longer than
any other polish at present in use.
What we claim and desire to secure by Letters Patent is, the above
described compound, substantially as and for the purpose herein set
forth.
In witness whereof, I, the said Robert Birch, have hereunto set my
