Abstract
Abstract In a study of the equilibrium swelling of rubber in thick oils, thin samples, about 0.1 mm thick, were required so that equilibrium could be reached within a reasonable time. Thin sheets can be molded, but they are frequently very anisotropic and therefore undesirable. Although it is possible to microtome very thin samples of rubber at sufficiently low temperatures where it is relatively stiff, only small areas are obtainable, and it is a difficult and inconvenient process if several square centimeters are required. An oscillating blade microtome of simple design was therefore constructed, capable of cutting sufficiently thin slices, about 2 cm square, at room temperature. Because of the sawing action of the blade the cutting force is greatly reduced and deformation of the sample is minimized.
