    Abstract: The present invention discloses an improved chain assembly and a method for making the same. In general, the method of making a chain assembly in accordance with the present invention, comprises forming a plurality of links having a preselected shape and placement of apertures therein. A plurality of wire blanks are formed having an outer diameter to permit insertion into the apertures of the links. Such link is retained in a fixed position and a wire blank is inserted into each aperture of the link. On one end of each wire blank, a head is formed having a diameter larger than the aperture into which the wire blank is inserted. A mating link is placed into engagement with each link containing wire blanks with the end of each blank inserted in one aperture of the mating link in a manner to form a chain assembly. On the other end of each wire blank, a head is formed to complete interlocking of the links and blanks in forming the chain assembly.

    Abstract: A system for controlling a gate includes a microprocessor which normally automatically recloses a gate after it has been opened in response to a radio or sensor loop signal, and which normally locks the gate against movement when the gate motor is stopped. When an obstruction is sensed in the path of the gate, the automatic reclosing feature and the sensor loops are disabled, the gate drive remains unlocked even though the motor is stopped, and the response of the system to a radio signal is changed to produce alternating opening and closing of the gate on successive radio signals. At all times, the gate drive lock is released before the motor is started and is not engaged until after the gate has come to rest. Field adjustment of the obstruction sensor is avoided by generating an obstruction signal only when the gate speed falls below the operating speed of a gate imposing the largest design load on the motor, and the speed at which an obstruction is sensed is adjustable in discrete increments by digital switches so that the specific load level at which the system sees an obstruction may be selected to fit various conditions.

    Abstract: A device for automatically opening and closing a hinged door includes a motor having a drive shaft, a speed reducer, an operating shaft adapted to be connected to the hinged door and operatively coupled through the speed reducer to the drive shaft, a chain sprocket fixed to the operating shaft, a chain trained in mesh around the chain sprocket, a first rod having an end coupled to an end of the chain, with a first fixed to an opposite end of the first rod, a second rod having an end coupled to an opposite end of the chain, with a second flange fixed to an opposite end of the second rod, a first tubular body in which the first rod is axially movably disposed, a first spring disposed around the first rod within the first tubular body for normally urging the first flange in a direction away from the chain sprocket, a second tubular body in which the second rod is axially movably disposed, and a second spring disposed around the second rod within the second tubular body for normally urging the second flange in a direction away from the chain sprocket. One of the first and second springs has a smaller spring force.
