Description
Louis A. Matos (ca. 1837-1910)—a Cuban immigrant who worked as a pharmacist in Philadelphia and assisted in the Spanish edition of the United States Pharmacopoeia—submitted this model, along with his patent application, to the U.S. Patent Office in 1868. The “BUCKELEW & WATERMAN PHILADA.” inscription refers to the firm that made the model. John D. Buckelew was a wealthy farmer from New Jersey who provided the capital for the scale maker, Albert G. Waterman. The “PATD JULY 7, 1863” inscription indicates the date of a patent issued to Sandy Harris, a former employee of the Customs House in Philadelphia. Matos’ counter balance was a modification of Harris’ design.
