Abstract

451,936. Door-operating appliances. HASLAM, F., 9, Ash Grove, Timperley, Cheshire. Feb. 5, 1935, No. 3656. [Class 65 (i)] A power-operated vertically moving shutter carries on its leading edge c a movable guard rail d, which actuates a limit switch to stop the motor when the closing movement of the shutter is prevented by any obstruction. In the form shown, the guard rail comprises two sections, each mounted on a pair of parallel-motion links and having a pin f<6> engaging a lever plate f<5> hinged to the shutter c and arranged to operate a plunger f<3> to open the switch. The switch is also opened at the end of the door movement by the guard rail striking the door sill.
