Patent number: 4466570Abstract: An insulated joint is provided for use between sections of rail that are disposed in adjacent signal circuits. The insulated joint includes a separator disposed between a pair of dielectric end posts. The end posts have a plan configuration substantially identical to the cross section of the rail sections with which they are used. The separator is constructed from a material having sufficient strength to enable it to withstand the forces exerted by the wheels of the train. The insulating fabric disposed between the joint bar and the rail is removed at least in the portion thereof adjacent the separator head portion thereby avoiding the problem of having the insulating fabric wear adjacent the separator. In locations where the separator would be subject to greater than normal forces, a head portion with a height greater than that of the rail sections is provided to increase the strength of the separator.Type: GrantFiled: September 16, 1982Date of Patent: August 21, 1984Assignee: New York City Transit AuthorityInventor: James T.

Patent number: 4464831Abstract: A method of fabricating an insulating joint between a pair of end abutting rail sections of a railroad track includes the suspension of a pair of opposed fishplates at the rail joint at spaced distances outwardly of the rail sides, and simultaneously heating the rail sections and the fishplates to a predetermined temperature for activating a heat-activatable adhesive provided in fabric cuffs which are disposed between the fish surfaces and the fishplates. The fishplates are shifted along guide rods of their support assemblies inwardly toward one another into place against opposed fish surfaces of the rail sections, and are thereafter bolted in place. A device for fabricating the joint includes a box-like hood on which heaters are mounted, or a shear assembly supporting the heaters and being clamped onto the rail head. The heaters may be adjusted to accommodate various rail profiles.Type: GrantFiled: February 10, 1982Date of Patent: August 14, 1984Assignee: Klockner-Werke AktiengesellschaftInventors: Lothar Weber, Friedhelm Wojtek, Horst Schwarzbach

Patent number: 4256259Abstract: A rail joint includes an insulative base piece insertable between a rail base flange and a joint bar. The ends of the base piece project longitudinally beyond the respective ends of the joint bar to provide exposed terminal sections with an intermediate central section. Longitudinal migration of the base piece during travel over the rail joint is precluded by one or more end abutment members fixedly disposed relative the base piece and including an elevated inner abutment surface intermediate the central section and each terminal section and engaging the joint bar ends. The abutment members may comprise integral elevated tabs cut from the base piece or alternatively, separate members insertable through cut-out portions in the base piece terminal sections.Type: GrantFiled: May 30, 1978Date of Patent: March 17, 1981Assignee: Portec, Inc.Inventor: William C.
