Rail anchor isolator
The present invention provides an isolator particularly adapted for use with a rail anchor utilized in an application where railroad rail is installed on concrete ties. The isolator protects the concrete tie from contact with the rail anchor caused by longitudinal movement of the rail due to train acceleration of deceleration or expansion and contraction due to temperature changes. In one embodiment, the isolator is comprised of a structural plastic material and includes a front face section and a rear face section. The front face section and rear face section each comprise a generally rectangular structure, having a top edge, bottom edge, and side edges. A center section joins the front face section and rear face section and forms part of the top of the isolator. In another embodiment, the front face section includes a top section and bottom section, with the top section having a lower edge projecting laterally at an acute angle from the bottom section. Similarly, the rear face section includes a top section and a bottom section, with the top section having a lower edge projecting laterally at an acute angle from the bottom section.

Railway anchor applicator
A railway anchor applicator for applying an anchor to a rail includes a frame configured for movement in a specified direction of travel along a track, and a workhead assembly movably mounted on the frame for movement toward and away from the rail. Also provided is an anchor receiving mechanism configured for movement between a first position receiving an anchor from an anchor input and a second position placing the anchor away from the anchor input. An anchor positioning mechanism moves between a retracted and extended position for positioning the anchor adjacent to the rail at either the field or gage side of the rail. An anchor clipping mechanism engages the anchor onto the rail by applying pressure on the anchor from the side of the rail and compresses the anchor between components of the anchor clipping mechanism so that compressive forces act on the anchor transversely across the rail.

InactiveUS9139959B2Minimise the emitted soundsRail anchorsRail fastenersEngineeringMechanical engineering
A system includes a guide plate, a fastening member and a resilient member, for fastening a rail on a solid base. The guide plate serves as a guide for the rail in the horizontal direction and as a stop for movements of the rail in the vertical direction. The guide plate has a contacting surface against which the longitudinal side of the foot of the rail rests. The resilient member which rests on the guide plate exerts substantially no hold-down force on the rail and merely supports the guide plate elastically against the clamping member. The resilient member is of a W-shaped or S-shaped configuration and, in the fitted state, a portion thereof projects sufficiently far over the foot of the rail for it to be retained resiliently by the resilient member if it is moved upwards in the vertical direction.
