Improvements in Brushes or Swabs for Liquid Blacking and
the like.
I GEORGE SIGFRIED WOLFF of 927 North Front Street in the City of Phila-
delphia State of Pennsylvania United States of America Manufacturer of Chemical
Compounds 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 :--
My invention comprises an improvement in that class of brushes or swabs in
which the swab holder consists of a wire suspended from the bottle cork my
invention relating especially to the brushes or swabs used in connection with
blacking compounds having alcohol as a solvent, and the object of my invention
being to prevent decomposition or deterioration of such compounds when the same
are kept in stock or are not used for long periods of time.
This object I attain in the manner hereinafter set forth, reference being had to
the accompanying drawing which represents a bottle of blacking having a swab
constructed in accordance with my invention.
It is a common practice to provide bottles of shoe blacking and like compounds
with brushes or swabs suspended from the bottle cork by means of a wire, for
instance, in the drawing, a represents such a swab, b the cork, and d the suspending
wire.
When such compounds have alcohol as a solvent, however, it has been found that
after a time the compound is decomposed and the new compounds formed are
worthless for the purposes for which the original compound was intended. This
decomposition I believe to be due to the presence of the naked metal wire in the
compound and my present invention consists in providing the said wire with a
coating or covering insoluble in alcohol, that which I have found to be preferable
for the purpose being simply a coating of glue, under which term may be included
animal glue, gelatine, fish glue, isinglass and the like.
In addition to coating the suspending wire it is also preferable to coat the bottom
of the cork so as to prevent deterioration due to evaporation through the pores
of the cork, the coating being applied after the wire has been inserted in the cork,
so that the said coating is continuous, that is to say, without the break which would
be caused if the wire were inserted into a previously coated cork.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is.
First. The within described swab or brush for bottles containing alcoholic
blacking compounds, or the like, the said swab or brush having a suspending wire
provided with a coating insoluble in alcohol, substantially as hereinbefore
specified.
Second. The within described swab or brush for bottles containing alcoholic
blacking compounds, or the like, the said swab or brush having a suspending wire
provided with a coating of glue substantially as hereinbefore specified.
Third. The within described swab or brush for bottles containing alcoholic
blacking compounds, or the like, the said swab or brush having a wire suspended
from the cork and provided with a coating insoluble in alcohol and extending
