Abstract

721,888. Two-part couplings combined with switches. PARSONS, Ltd., C. H., and HANDLEY, G. B. Dec. 2, 1952 [Jan. 11, 1952; June 18, 1952], Nos. 857/52 and 15315/52. Class 38 (1). [Also in Group XXXVII] A cover, fuse holder, plug or other removable part is interlocked with an electric switch by co-operation of a spring-loaded obstructor on the switch and a locking pin on the removable part, so that this can be removed only when the switch is off, and the switch cannot be turned on when this part is absent. When switch lever 19 is moved, pin 21 carried by it and engaging in a hole in an arm 33 rotates this arm about its pivot 32 so that a finger 38 causes slide 41 to move to or fro. This movement is prevented when fuse holder 14 is absent, by the engagement with a shoulder 41a of slide 41 of a spring-loaded plunger 29 which projects through a plate 23 mounted on the switch base 11. When the fuse holder 14 together with cover 12 is replaced, pin 44 depresses plunger 29 and slide 41 is freed to move with its edge in a recess 45 in the pin, this engagement preventing the removal of the fuse carrier while the switch is on. In a modification the finger 38 of the pivoted arm 33 engages the plunger 29 itself, or moves when freed, in the recess 45 in pin 44, Figs. 4, 5 (not shown).
