Abstract: 577,794. Retarding action of switches. GENERAL ELECTRIC CO., Ltd., TURNER, H. C., and BRETT, F. J. May 15, 1942, No. 6619. [Class 38 (v)] [Also in Group XXXII] Relates to an electric circuit breaker arrangement of the type comprising an overload trip relay, the contacts of which are adapted to be closed on the occurrence of an overload by the movement of a movable element, and a dashpot adapted to restrain the movement of the element, so as to retard the closure of the contacts, in accordance with the rate at which liquid passes through a narrow channel. According to the invention, the dashpot comprises a relatively wide channel bypassing the narrow channel and means are provided for opening or closing the by-pass according as the pressure difference between the ends of the wide channel, produced by the movement of the movable element towards closure of the overload trip relay contact, is respectively above or below a predetermined limit. As shown, the movable element is constituted by the piston rod A which terminates in a piston B working in the dashpot cylinder C, upward movement of the rod, to close the relay contacts beingrestrained by flow of fluid between the periphery of the piston and the cylinder wall or by a hole in the piston constituting the narrow channel. An orifice D in the bottom of the cylinder is connected by a valve chamber J and pipe E with the part of the cylinder above the piston, flow of fluid from the pipe E and out through the orifice D, which parts constitute the wide by-pass channel, normally being prevented by a screw-adjustable, spring-pressed ball-valve F. In an alternative construction in which the downward movement of the piston is resisted, the ball-valve co-operates with the orifice D. With normal overload the normal time-delay occurs but with an abnormal overload the delay is greatly reduced.
