Abstract
616,899. Two-part couplings. DUKE, G. E., and NICHOLSON, C. H. Oct. 15, 1947, No. 27966/46. [Class 38 (i)] Closure of a circuit through the coupling 10, 15 by rotation of a switch-operating spindle 14 by a handle 39 is prevented if the removable part 15 of the coupling is not in position on the fixed part 10; further, a lug 48 prevents removal of the part 15 when the switch is " on," by engaging a cam plate 36 fixed to a non- circular portion 32 of the spindle 14. The latter is slidable and rotatable in a flanged bush 13 and is connected by a fork 25, urged by a spring 30, to a switch-operating member 26. The cam plate 36 and the bush 13 enclose a spring 43 and have co-operating conical surfaces. The handle 39 has projections 38 engaging the cam plate, and a sleeve portion 40 containing a spring 50 which is retained by a washer 35 secured to the end of the spindle 14. When the handle is turned with the part 15 not in position, a lever arm 45 on the cam plate is obstructed by a stop 18 of the coupling part 10, but when the coupling part 15 is in place an inclined surface 46 of the cam plate engages the lug 48 and is moved upwards, thereby raising the arm 45 clear of the stop 18 and permitting closure of the switch. Removal of the part 15 enables a lid 22 to drop by gravity and close the part 10.
