Until 1880 the US Patent Office required that all patent applications be accompanied by a model; in the case of mechanical objects by a working model. Almost from its inception the USPO was vulnerable to fires, with perhaps the most serious one being that of 1877, when 80,000 patent models were destroyed. Fortunately many survived unscathed and among them this 1875 model for a dental drill issued to S.S. White, this country’s most successful 19th-century manufacturer of dental instruments. Dental patent models are quite scarce. Until the Gary Lemen collection was sold in 2012 I had never seen one for sale. This one is ex-Lemen Collection. It was bought by Dr. Lemen in the 1960s as part of a small collection he came across in a Washington,DC antiques shop. The patent for the drill was issued on August 31, 1875 (No. 167,208). If you go to Google Advanced Patent Search and enter that number you can read the details of the submission.
