C. Winter

On 12th of April, 1859, C. Winter of Piqua, county of Miami and State of Ohio, was granted a 3-pages USA patent number 23637 for a single column adding device, which seems to be the second in the USA, after the machine of Parmelee, and fourth in the world, after the machines of Torchi and Schwilgué (see the first page of the Winter's patent below).

In contrast of the machine of his compatriot Parmelee however, the machine of Winter was manufactured and two devices are known today—one of them belongs to the Smithsonian Institution in Washington D.C., and second is a property of Auction Team Breker, Koeln, Germany (see the photos below).

The size of the machine is 27 x 22 x 25 cm. The box is made from oak, with ivory key taps and two dial faces on top of registers. The base part of the internal calculating mechanism is the ratchet-wheel (marked with K on the patent drawing), which is provided with 100 teeth, bevel-wheels j and i, pawls s and z, cord o, and pulley P. The big dial B is divided to 100 divisions, while the smaller dial C is divided to 6 divisions.
