A Trouble-Free Aerial Pole

"THERE is a method of mounting an aerial pole which is not a new idea, put which is not utilised as much as it should be, when the great convenience is considered. This system makes erection of the pole easy, and also allows of every access to the top at any time by simply withdrawing a bolt, releasing the backstay, and lowering the pole, hinged at its lower extremity. Reference to the diagram shows the arrangement in a way that requires little explanation. Two uprights of 8 x 2 timber are connected on their lower halves by suitable strips of timber, braced as shown. The space between the two uprights is the width of the pole, 2%

inches square being a suitable dimension for a 30 or 40ft. pole. Near the lower end of the pole a 4-inch hole is drilled, and corresponding holes in the uprights take a long half-inch bolt to act as a hinge. When the pole has been raised, it is held in place by @ bolt passed through .a hole drilled in each upright, and the pole, eighteen inches above the lower bolt. The usual stays are provided to steady the pole, which may easily be lowered at any time by two persons, only the backstay being released. The pole should, of course, be placed so that when lowered its length is clear of fences, and can lay along clear ground if possible. With such an arrangement the breaking of a halyard or pulley fastening will cause little ennearn to the owner.
