Abstract
210,169. Reyrolle & Co., Ltd., A., and Mirrey, J. Oct. 27, 1922. Oil switches; covers. - Means for securing the cover of, for example, an oil-immersed switch-fuse box comprise two catches at the front of the cover, both being eccentrically mounted on a common operating shaft carried by the casing, and other catches, one on each side, near the back or hinged portion of the lid, which are mounted on eccentric bushes linked to the operating shaft, so that all the catches can be operated by a single handle. Arms mounted on the operating shaft assist the initial opening movement of the cover when the catches are released. The cover A<1> is counterweighted and hinged at B, and carries lugs D, D<1> cooperating with catches C, of which two are mounted on eccentric bushes E on a shaft F, and two on eccentric bushes E'. The catches C are simultaneously operated by a handle G, which first lifts them by means of the eccentrics E, E<1> and then, by rotating the cranks H, J to engage pins C', rotates them free of their lugs D, D'. The catches are restored by spring plungers K engaging their tail ends C', while arms C<2> thereon engage the lid to assist the initial opening movement. Padlocking means are also provided to prevent unauthorized use, and if the box is mounted high up, the handle is extended so as to be within reach from the floor level.
