Hair clippings are prevented from passing through the opening 23 by means of resilient sealing members 64 having T-shaped ends received in correspondinglyshaped slots 65 on each side of the armature laminations. One end of the shaft 33 is bifurcated to receive a rocker bar 48 provided with recesses 45 to receive the ends of springs 46 the other ends of which are received in recesses 47 in the inner faces of projections 19f, 19g on the support 19, the springs, which have a natural frequency approaching that of the alternating current supplied to the field winding 30, serving to bias the armature poles 38, 39 to the rest position, Fig. 3.
