Jenney Versus Deadman Convenience Should Be Sacrificed to Safety inRaising Poles By G. H. McKelway Engineer of Distribution, Brooklyn Rapid Transit System IN THE Aug. 17 number of the Electric RailwayJournal, Charles R. Harte continued the series ofadmirable articles on overhead construction which hehas been contributing by explaining the proper way toset wood poles. I have found these articles the bestand most helpful that I have ever seen on the subject. In the latest article he mentions the jinny as asubstantial prop of Y-shape about 7 ft. long. Whilethat name may be the one commonly used for the toolin Connecticut, it is a misnomer so far as some otherparts of the country are concerned. In order to assure. SETTING A STEEL POLE WITH A JENNEY myself of the fact, I looked the tool up in severalcatalogs of line material which are distributed overall of the United States, and found that in them thejenny or jenney is made in the shape of an Xrather than a Y, and is therefor built to rest with twofeet on the ground. The prop of Y-shape is generally spoken of as eithera mule or, more commonly, a deadman. Whilethe latter is the more universally used, principallybecause of its greater convenience, yet the other type,which is not mentioned in Mr. Hartes article, is thesafer, though undeniably the more clumsy. With theordinary deadman there is always the possibility ofa pike or piker slipping or something else occurring,which will throw the entire weight of the pole to oneside. In such a case it is very difficult to keep thedeadman upright and there is great liability of thepole tumbling to the ground and seriously injuring oneof the men who are attempting to raise it.
