James Tilghman, New York city.--This is a combined brush and stopper,
consisting essentially of a handle having a stem and a flat end
corresponding to the top of the cork. The brush has a flat head,
corresponding to the bottom of the cork. The cork is interposed
between the said head and end of the handle, and held in place by the
central stem.
