The shoes are constructedin the following manner: One man brings the large pieces A to a red heat in the furnace,Fig. 2; a second man fastens the piece B by striking it from theside, inserting a piece of sheet zinc mm in thickness betweenthe contact surfaces; the same man assists in inserting the wedgeby holding a heavy hammer against the surface. A third man takes the glowing piece Aout of the furnace andplaces it in position directlyopposite the smaller pieceB. He then strikes it witha heavy hammer and insertsthe wedge C. Before thisact, however, the secondman has placed a piece ofsheet zinc mm in thick-. are to be removed the shoe can be taken off without very muchdifficulty, and can be used again. The shoes, which have been usedon six street railways, two mountain roads and one heavy steamroad in Austria, are said to have stood severe tests most success-fully during the past year in all sorts of weather. Not a singleshoe has become loose, and the electrical contact was reported tohave been as good after a years usage as it was at the beginning. -Measurements made by the K. K. Railway department at Linzhave shown that while the tracks moved formerly about 45 mmeach year, this had been decreased to 9 mm when the boltless shoewas used. It was further shown that the expansion of the railswas in no way interfered with, and that the cars could pass overthese rails without any jars or jolts. The shoe is made in lengths
