Brush

These small brushes served several purposes in clockmaking and watch repairing. One of their functions was to help correct the gradual accumulation of dirt in the watch or clock wheels. Nathaniel IV probably made these brushes by encasing hog bristle in copper tubes. Eighteenth- and early-nineteenth-century sources do not illustrate brushes used by clock- and watchmakers, perhaps because they were made by the craftsmen who used them and were not commercially available in quantity as were many other tools.
