ABSTRACT:
An electric motor moves drapes on a carrier by a cord wound on a sheave attached to a shaft thereof. The motor is attached to a housing along with a second shaft. The second shaft has an arm on an end thereof and carries a disc with first and second cam surfaces thereon and an axial projection. An arcuate slot on an end cap receives the projection on the disc. In response to an actuation signal, a control activates the motor causing the shaft and sheave to rotate and linearly move the cord and drapes. A limit member on the cord engages the arm and rotates the second shaft causing the first cam to close a first switch and cancel the actuation signal while the second cam closes a second switch such that the rotational direction of the shaft is reversed on receipt of a next actuation signal.
