The machine is composed of a brass case with fine crafted shafts in ebony. The case stands on 4 small finely-worked ebony feet. The upper part of the machine is called the console, and consists of a top part containing windows. Through these windows, figures inscribed on cylinders can be seen. A moving bar enables either the upper or the lower row of figures to be masked, depending on the operation to be performed. In the upper position, it enables additions; in the lower position, it enables subtractions. The two rows comprise the totaliser. The lower part of the console contains the input register. This is composed of a series of wheels whose upper part is called the limb. Inside each wheel is a daisy wheel. It is by using these daisy wheels, placing the stylus between two branches of the wheel, that the numbers are input, by turning to the right and bringing the daisy wheel up to the limb end-stop. This model, called “the Knight Durant-Pascal’s machine”, had 5 wheels on its input register, and therefore 5 windows on its monetary-base totaliser. |
