Haff Game Counter, U.S. Patent Office Model

Haff, Le Roy B. · 1881

This small and incomplete model from the U.S. Patent Office well illustrates the technology used to store information about patent models. Attached to the knob by red tape are two labels. The smaller tag records the entry of the model into the office on March 17, 1881. It indicates in pen the name of the inventor, Leroy B. Haff, the type of the invention (a game counter) and the date received. The front of the tag also is marked in pencil “issued.” The back of this tag also has the pen marks S 28482, 23 Div, and 84/1044.
