Title: Drive device, especially for washing machines
IPC: D06F37/36
Filed: 1982-08-30
Abstract: In a drive device, especially for washing machines, two concentric belt pulleys of differing diameter are mounted freely rotatably on a hub designed to be coupled to a drive source, whilst essentially radially movably guided flyweights, spring-loaded towards the axis of rotation and carrying coupling elements for the large and the small belt pulley, rotate together with the hub. When the flyweights are in a radially outer position, the hub is coupled to one (the large) belt pulley by means of coupling elements arranged on the flyweights, whilst, when the flyweights are in a radially inner position, the other (smaller) belt pulley is connected fixedly in terms of rotation to the hub via such coupling elements of the flyweights. A randomly trippable retention device having a trip element actuatable from outside makes it possible to lock the flyweights in the radially inner position. In order to achieve silent operation, along with low wear and a long lifetime and along with a simple construction, the retention device (20, 26, 18) has a control device (30, 41) which automatically acts dependent on rotational speed and by means of which the flyweights (13) can be held in a middle position, in which the coupling elements (17, 18) are out of engagement with their two belt pulleys (3, 21).

The interval between the intants of closure of the two switches represents the amplitude and rapidity of movement of the object. Slight displacements or vibrations will not cause both switches to close due to the distance separating them but sudden violent displacements caused by a bag being snatched will cause an alarm. - The switches may be constituted by interdigitated printed conductors on a circuit board, the spacing between the conductors being such as to allow them to be bridged by the conductive sphere. Various forms of electronic monitoring circuit are described to trigger an alarm device in response to the two switches being closed in response to violent movement of the conductive sphere, using bistable circuits. The path has zones of differing curvature to provide a variation of the movement sensitivity.  (4/55)
