          37. Gregg tilting hand brake.
        
        
          introduced by Gregg Manufacturing in the early 1930s. The tilt-
        
        
          ing brake wheel could function in both positions. When in the
        
        
          down position, it could impede a trainman attempting to board
        
        
          a moving train.
