��A Machine to Pull up old Telegraph Poles

ONE of the most difficult tasks fall- ing to the lot of the telephone or telegraph lineman is that of removing a pole which has been firmly embedded in the ground for a number of years. It is often necessary to dig the post out of its bed.

A Chicago concern has recently placed on the mar- ket a jack which is said to be able to accomplish this task in a few minutes. The device is very similar to an ordinary automobile jack, but is larger and many times as powerful. In the illus- tration is shown a pole which was fixed five feet in the ground, and which had been embedded for eight years. It took the jack nine- teen minutes to pull the pole from the ground.

A chain, with a grab hook attached, is fixed to the Hft of the jack, and is passed once about the pole. The lift extends two feet; then it may be lowered and the chain given a new grip. The capacity of the jack is fifteen tons, large enough, it is claimed, to uproot the most stubborn pole. The amount of time and labor saved by this machine are worth considerine.

The vehicle is composed mainly of outer cases, which range in size from twenty-eight by three up to thirty-seven by four and one-half inches and are set upon a frame of light timbers. The seat is formed of cartons containing' inner tubes; the dash is made of cardboard, on which are fast- ened patches and repair ma- terial tins to imitate speedom- eter and lighting systems ; the exhaust is composed of a tube, stiflfened within by card- l)oard to keep it rounded. In the seat is a driver who gives the final racing touch by grip- ])ing the famous Barney (^Id- liold cigar in the comer of his mouth. As yet, no one has tried to buy this car. though it will undoubtedly be sold piece by piece.
