Drapery actuating mechanism having dual timer

In a mechanism for opening and closing at least one closure member, a cord being associated with the closure member and having a bight portion and a pair of reaches extending from the bight portion, the mechanism comprising a drive roller for driving engagement with the bight portion of the cord, and electric motor means having first and second winding portions for respectively rotating said drive roller in opposite directions, the improvement comprising:

• first and second timed switching means for selectively supplying power to said electric motor means, said first timed switching means having first adjustment means for setting times at which power to said electric motor means is initiated, said second timed switching means having second adjustment means for setting an interval after which power to said electric motor means is terminated, each of said timed switching means including at least one pair of contacts and control means for selectively opening and closing the associated pair of contacts, and third switching means having first and second sets of contacts respectively disposed in opposite conditions and direction control means for controlling the conditions of said sets of contacts, the control means of said first timed switching means being coupled across a source of power and being operative to close its associated pair of contacts for selected durations in accordance with the setting of said first adjustment means, the contacts of said first timed switching means being coupled in series with the source of power and the control means of said second timed switching means, the contacts of said second timed switching means being coupled in series with the source of power and said direction control means, said first set of contacts being coupled in series with the source of power and said first winding portion, said second set of contacts being coupled in series with the source of power and said second winding portion, said direction control means being responsive to said second timed switching means for reversing the conditions of said first and second sets of contacts each time said second time switching means is actuated, whereby said motor means is caused to rotate in a direction opposite to its direction of rotation the previous time power was supplied to said electric motor means.
