Abstract

926,396. Switch handles. LICENTIA PATENT - VERWALTUNGS - G.m.b.H. June 16, 1961 [June 23, 1960], No. 21823/61. Class 38 (5). [Also in Group XXIV] In a removable crank handle for a power transformer tap-changing device, a slip-on sleeve 2, having a drive-slot 1. is connected to a crank-arm 13 through an adjustable slip coupling comprising a friction or facially toothed disc 6 clamped between a disc 5 pinned to the sleeve 2, and a disc 7 welded to the arm 13, by a spring 8 adjustable by a nut 10 covered by a screwed cap 12.
