DescriptionThis spiral slide rule consists of three concentric cylinders. The outermost papier-maché cylinder is covered with the spiral slide rule scale. This cylinder is mounted on felt and smoothly slides over another cylinder within it.
This middle cyclinder is covered with paper printed with various mathematical and engineering tables. The cylinder is fixed to the wooden base and handle of the slide rule. The base supports a vertical brass index, which terminates in a point.
The innermost cylinder slides inside the middle cylinder, which is lined with thick felt. This cylinder is made of brass. The top of the cylinder is fixed to a wooden cap that funnels gracefully into an opening that enables one to look down the barrel of the cylinder. The wood cap carries the primary brass index for the slide rule. This brass index is graduated and has several notches.
The foot of the outermost cylinder and matching stop on the wooden base are both brass.
The mahogany case has a lock, but the key is missing.
