    Abstract: A door opener system which includes a compact unit containing a motor, circuitry and various accessories, which can be quickly connected to and disconnected from the operator system, said motor having a first gear which easily is positioned into a meshing relationship with a second gear upon connection of the compact unit to the operator system. The operator system further includes the use of only two common switch actuators for operating the motor to move the door in open and closed positions, and to stop the motor upon the door striking an obstruction in its path of travel, said actuators being cooperatively associated with a cam actuator and drive chain pressure responsive means. Also, a unitary gear and drive sprocket structure is utilized in the drive system. Finally, an adjustable shock absorber type draw bar interconnects the door to the chain drive.

    Abstract: An overhead control for raising and lowering garage doors and other cyclically operated devices which utilizes a unidirectional electric motor which drives an endless chain in only one direction. A follower rides on a rail and is coupled to the endless chain by a gear which engages the chain on one side so as to move the follower in a first direction. When the follower reaches the end of the rail, the gear of the follower rotates 180* so as to engage the opposite side of the chain and thus move the follower in the opposite direction. The tension may be adjusted so that a door will stop or reverse when it meets resistance sufficiently firm to shift the gear of the follower.

    Abstract translation: 用于提升和降低车库门和其他循环操作装置的顶置控制装置，其利用单向电动机，其仅在一个方向上驱动环形链。 跟随者骑在轨道上并且通过齿轮联接到环形链条，该齿轮在一侧与链条接合，以沿着第一方向移动从动件。 当跟随器到达轨道的端部时，从动件的齿轮旋转180°以与链条的相对侧接合，从而沿相反方向移动从动件。 可以调整张力，使得当门抵抗足够坚固以阻止从动件的齿轮移动时，门将停止或反向。
