Abstract

133,924. Coles, C. H. June 24, 1919. Regulating-switches.-The switch arms 3, 3<a> which are used to regulate the current in two separate circuits, carry two links 6, 6<a> on pivots 5, 5<a> and connected by a pivot 7 at their outer ends which are provided with stops 8. The arms are shown in the off position. When one arm is moved to the full on position, the links 6, 6<a> are fully extended. If then the second arm is operated, the first arm is moved back to a corresponding extent as the second advances so that a certain aggregate current in the circuits cannot be exceeded. The circuits controlled may be of those of kinematograph projectors or of a projector and the lamps of the building.
