Abstract

322,884. Burleigh, D. S. Nov. 30, 1928. Driving-arrangements.-A flexible and electrically insulating coupling between the spindle b of an electric motor a and the worm spindle e of a gramophone gearing consists of a helically coiled spring whose centre convolutions f<2> are more widely separated than the end convolutions f<1>, f<1> which engage collars k on the spindles b, e. The ends of the spring are seated in annular grooves m cut in annular insulating discs l pressed into the collars, and for positive engagement the springs may have axial pin portions f<3> which enter holes n in the insulating discs.
