Abstract

There is disclosed a mechanism adapted to produce a plurality of different motions of a member affording a point for application of a force comprising: fixed disc means held in a fixed orientation; and at least one moveable disc means adapted to rotate around its origin and around the origin of the fixed disc means under the influence of the applied force; in which: the ratio of the radius of the fixed disc means to the radius of the moveable disc means is 2:1; the position of the point which the force is applied to is radially variable relative to the origin of the moveable disc means; and the moveable disc means is in communication with the fixed disc means so that rotation of the moveable disc means around the origin of the fixed disc means at a frequency f causes rotation of the moveable disc means at a frequency of 2f.
