Abstract

The device is used to balance two movable machine parts, one of which is carried by the other. The first is mobile in the vertical sense on a base and the second is pivoted (6) on the first about an horizontal axis. The counterweight (4) is connected to a flexible, inextensible tie (15), part of which passes onto one or more guide pulleys (16) carried by the base (1) of the machine. The other part also passes over a guide pully (18) carried by the base and is connected to the second machine part (5, 11) by links so that its direction passes through a particular joint (A) of the second machine part in projection, and between two points (G, O) which are the projections onto the vertical plane of the centre of gravity of the second machine part (5, 11) and of the pivoting axis (6) respectively.
