the motor 54 the pendulum arms 18 may be freely adjusted in length to control the desired frequency of operation of the reciprocation referring now to fig1 and 5 by mounting the motor 54 in a central location on the hanger bar 16 access on either side of the motor may be had for hangers 24 and the loading of the hanger bar 16 may be evenly distributed reducing any tendency of the hanger bar to reciprocate off the lateral axis 20 a cover 64 may be placed over the motor 54 and attached to the ceiling 14 or to an upper cover and to the rear wall 70 of the cabinet to fully enclose the mechanism of the motor 54 the coupling between the motor 54 and the side walls 12 of the cabinet is force limited by the elastic cord 60 and thus the hanger bar 16 protruding from the cover 64 may be stopped by hand and high forces are not generated in the event of jamming of the hanger bar 16 or catching of clothing or the like adjustment of the force may be by adjustment of the spring constant i e thickness of the elastic cord 60 and the eccentricity of the crank disk 56 the cover 64 may include courtesy lamps 66 for lighting the inside of the cabinet when the cabinet.
