Abstract
563,542. Automatic circuit-breakers. LANDIS & GYR SOC. ANON. Feb. 26, 1943, No. 3185. Convention date, March 14, 1942. Addition to 563,528. [Class 38 (v)] The invention of the parent Specification is modified in that the release lever 12, which is freely rotatable on the cross-piece 4 connected to the toggle levers supporting the movable contacts (not shown), is formed as a flat piece with its centre of gravity located below the cross-piece 4, and cranked in one plane so as to define a centre part 12b, eyelets 48 by which it is pivoted to the cross-piece 4, and lugs 12a engaging in V-notches in bearing pieces 37 on the spring toggle-levers 8, 10. A catch 40 rotatable on a pin 41 secured within the button 1 has a shoulder 42 which engages cross-piece 4 to close the breaker when the button is depressed, the breaker being retained closed by hooks 50 engaging the cross-piece. During closure, the spring 45 changes its bearing point on catch 40 to a point above pivot 41 so that, when the operating force is removed and a spring (not shown) tends to return the button, the catch 40 is rotated'so that nose 43 engages under cross-piece 4 and holds the button. When the button is again depressed, surface 44 of nose 43 acting in the opening 49 in lever 12 rotates the latter so as to deflect hooks 50 and also to bear on surfaces 38 of bearing pieces 37 and break both toggles. If either toggle is broken on overload, its associated bearing surface 39 tilts lever 12 which acts on the surface 38 of, and breaks, the other toggle. Indicator.-The catch 40 is formed with " on " and " of " indicating plates 46 visible through a window 47 in the button.
