    Abstract: A door holder-closer comprising a conventional door closer and a novel electromechanical door holder attached to the drive spindle of the door closer. The door holder features a lever which is coupled to the drive spindle of the door closer by an adjustable clamp comprising mating rotor and cone elements. Both the rotor and the cone are seated over the drive spindle with the cone being fixed to the spindle. The rotor is formed with a projecting rotor tab which is selectively engaged by a pawl. The lever is formed with a notch which selectively engages a roller driven by an electromagnet-actuated armature. The motion of the door closer spindle is restrained by a primary latch formed when the roller is seated within the lever notch in response to an energized electromagnet, and by a secondary latch formed when the pawl engages the rotor tab. The primary latch supports and controls the secondary latch. Hold-open door control occurs when both latches are in effect concurrently. If the primary latch is broken, either in response to deenergization of the electromagnet or the application of a manual overriding force on the controlled door, the secondary latch is automatically released and the hold-open mode terminates. The hold-open mechanism, which has as its principal components the rotor-cone clamp, the pawl-rotor latch and the electromagnetically actuated lever-roller latch, may be fabricated as a separate and integral unit that is simply seated upon the door-closer drive spindle to add a door-hold function to the door closer.

    Abstract: A sliding door is operated automatically by means of a nut and threaded rod which are driven by a reversible motor and constitute a reversible-action motion converter. The motor supply circuit comprises a switchable speed-reduction resistor, a protective resistor in series with the motor and a switchable voltage-limiter which can be connected in shunt across the motor terminals at the end of travel of the door-leaf.
