Description:
Most of the patents prior to 1836 were lost in the Dec. 1836 fire. Only about 2,000 of the almost 10,000 documents were recovered. This is one of the recovered patents. This patent is in the database for reference only.

For an improvement in the Rubbing Down and Polishing Combs by "twin buffs;" Lewis B. Prindle, and David Curtis, Fairfield, Connecticut, October 10.

"Instead of using one buff, in the ordinary way, the patentees cause two circular buffs to revolve in reverse directions, with their faces in contact; these buffs are covered with some spongy material, and are charged with pulverized English brick, for rubbing down, and with rotten stone for polishing, or with any substances possessing similar properties. Between these buffs, the backs of the combs to be rubbed down, or polished, are to be held.

It is unnecessary to describe the mode of driving the mandrels upon which the buffs are placed, as any workman can effect this. The novelty for which the patent is taken, is, manifestly, the twin buffs."

Description from the Journal of the Franklin Institute, V5 1830 pg. 24.
