Abstract
377,816. Retarding action of switches. MUDIE, A. B., 81, Billesley Lane, Moseley, Birmingham. July 31, 1931, No. 21857. [Class 38 (v).] An adjustable dashpot for use with electric switches has a series of holes or recesses formed in the cup or sleeve and an external lug on the sleeve or cup, the lug carrying a locking member for co-operating with these holes or recesses. As shown in Figs. 1 and 3 the cup or cylinder which is screwed to a threaded portion 17 of a sleeve 13 has a helical row of recesses 21 formed in its outer surface, these recesses corresponding to a number of settings of the dashpot. On a flange 16 of the sleeve 13 is secured a lug 18 in which is mounted a laterallyprojecting screw 22 having a pointed end which can be screwed inwardly to lock a projection 20 of a blade spring 19 secured to the lug into engagement with any particular selected recess 21. When the screw is slackened and the cup rotated the projection 20 clicks into the recesses 21 in succession until the desired recess is reached when the screw 22 can be retightened. The screw thread 17 is a quick pitch thread or a double thread may be used. The lug may alternatively be mounted on the cup and the series of holes or recesses provided in the sleeve.
