Description:
This small device has a tin case painted yellow and green on top and red around the edge. The top of the case has four wheels drawn on it, each of which has the digits from 1 to 9 drawn around the edge. The digits go clockwise for the first and third circles (marked “Cents” and “Dollars” and counterclockwise for the second and fourth circles (marked “Dimes” and “Dollars”). At the top of each circle, at the zero position, is a window that reveals a rotating disc below. The discs are rotated using thumbscrews that protrude from the back of the instrument. An arm on top of each circle points to a digit on the wheel. The discs advance when they are rotated in the direction of increasing digits and remain fixed when the arrows are moved back to zero.
The machine is marked on the front: SALES REGISTER. It is also marked there: E.J. HOADLEY (/) MANUFACTURER OF SPECIALTIES IN CONFECTIONERY. HARTFORD, CONN, U.S.A..
The Brooklyn City directory for the year ending May 1, 1890 lists ten men named William Lang.

Lang, a tuning-peg.
