Abstract
5805. Flood, W. H. March 10. [Cognate Application, 15,211/09.] Switches, quick-action.-In a quick make-and break electric switch, the movable contacts are provided with lateral pins which move in slots in a frame, the slots being inclined to one another ; the movable contacts are carried by the frame and a driving-plate is pivoted to it and is actuated at one end by the switch handle, and at the other end engages the movable contact. As applied to a single-pole switch, the fixed contacts b, Fig. 4, are mounted upon the base a and the movable contacts c are mounted upon the ends of two rods d, the other ends of which pass into holes in the block e. Between the block e and stop f<1> upon the rods, spiral springs f are coiled. Projecting from the block e and the stop f<1> are pins h<1>, i<1> which move in slots h, i respectively in the frame g. The handle j is forked to engage with the block e, and the driving-plate k is pivoted at the centre ; one end engages with the handle, and the other end engages with the movable contact. To move the switch from the open position to the closed position shown, the handle is moved to the right, the pins h<1> are lifted from the bottom of the slots h, and the movable contact is pressed down by the driving-plate k, the springs upon the pins d producing a quick movement of the contact c towards the fixed contacts while the pins i<1> pass along the slots i. As applied to a switch which may serve as a single-pole, double-pole, change-over or two-way switch as desired, the movable and fixed contacts are duplicated, as shown in Fig. 6, and the projecting ends of the pins h<1>, i<1> engage in notches o in the driving-plate p pivoted upon the casing g. The handle j engages both the pins h', one on each moving member. In operation, starting from the position shown in Fig. 6, one or other of the contacts c, c<1> may be moved into the closed position by turning the handle in one direction or the other. In this movement, one of the pins h<1> serves as a stationary fulcrum for the handle while the other is moved by it. By pulling the handle away from the base, both driving-plates are operated at once and both switches closed. In this position, either of the switches may be opened by turning in one direction or the other.
