Automatic gate

An improved electrically operated gate comprising:

• a rectangular frame having a top horizontal rail, a bottom horizontal rail, and vertical ends;
• a roller adjacent each end extending below said bottom rail by which the gate rolls from an open to a closed position and vice versa, the gate moving in a longitudinal vertical plane;
• means engaging said top rail to maintain said frame in a vertical plane;
• an inverted horizontal rack affixed to said frame on one side thereof, the rack providing a series of equally spaced teeth;
• an electric motor drive means affixed at a stationary position adjacent the gate frame and having a pinion drive gear rotatably extending therefrom, the pinion drive gear being below said rack and in engagement with the rack teeth;
• and
• means of resiliently urging said pinion gear upwardly into engagement with said rack teeth whereby when said electric motor drive means is energized said gate frame is longitudinally moved to open or close the gate depending on the direction of rotation of the pinion gear.
