Show Automatic Elevator Door Closer A simple and inexpensive construction has been devised for automatically operat ing the sliding doors guarding the exposed ex-posed landings of passenger elevators and by means of which all the doors in the elevator shaft are held positively closed except the door at the particular landing where the car is stopped The car can thus be moved from a remote landing and brought to any other above or below closing the door of the landing it leaves without requiring the services of an attendant at-tendant on the car The apparatus may be readily applied to all elevators old or o new where the doors slide on rollers and can be easily manufactured and put in place by any good mechanic Kew York Telegram |
