摘要： The specification describes an improved railroad track expansion joint which is comprised of a pair of longitudinally aligned elongated joint members interconnected with one another by means of a dovetail joint formed along abutting faces which extend at an acute angle to the members. The other ends of the joint members are connected to conventional rails and any expansion and contraction of the rails will cause the members to slide relative one another along the abutting face.

摘要翻译： 本说明书描述了一种改进的铁路轨道膨胀接头，其由一对纵向对准的细长接头构件组成，该纵向对准的细长接头构件通过沿着邻接面形成的燕尾接头彼此互连，该邻接面以与构件成锐角延伸。 接头构件的另一端连接到常规轨道，并且轨道的任何膨胀和收缩将导致构件沿着邻接面相对彼此滑动。
