A railway anchor spreader has a rotating plate on each side of each rail, with the bottom of each rotating plate having a pair of jaws. The tie plates are lowered until the jaws strike the ballast, and the tie plates are then pivoted first in one direction, and then in the opposite direction, by a hydraulic cylinder located near the top of the anchor spreader plates. The jaws will thereby strike the tie plates, first pushing them in one direction and then in the opposite direction, to move the rail anchors away from the tie. The shape of the jaws ensures that pivoting the anchor spreader plate will not cause the jaws to strike the tie as well as the tie plate. A rail clamp capable of grabbing rails of various sizes is also provided.

A tie exchanger assembly is mounted upon a truck and is used for removal and insertion of ties in a railroad roadbed. A boom is mounted to a rail clamp table which is vertically movable between an upper stored position and a lowered operable position. The boom is mounted to the center of the rail clamp support table and is rotatable 180. degree. about a vertical axis so that the boom may be used for manipulating ties on both sides of the vehicle. Rail clamps and rail engagement wheels are mounted to the underside of the rail clamp table. The boom is pivotable about a horizontal pivot axis. A tie clamp is mounted at a distal end of the boom. A self-aligning tie clamp may advantageously be used so as to clamp concrete ties or other ties with irregular or concave surfaces.

A rail maintenance vehicle includes a slide frame along which a grinder may move while the vehicle remains stationary. The grinder may be moved automatically away from the rail as the grinder moves longitudinally along the rail away from the center of a weld bead in order to smooth the grinding at the weld bead. The slide frame is connected by a linkage mechanism such that the grinder may be oriented at different grinding angles over a range of 200. degree. The grinder is mounted upon a lateral displacer such that the grinder may be moved from one side of the vehicle to the other for grinding on rails on either the right or left side of the vehicle. A turntable system allows the turntable cylinder to pivot up and out of the way to a horizontal position so that the lateral displacer may move the grinder from one side of the vehicle to the other without interference from a vertical turntable cylinder.

A tie remover/inserter machine uses the vehicle and bucket of a conventional backhoe with various modifications. Grader blades are added to the loader bucket such that the machine may be used for grading ballast along a railroad track. Rail engagement wheels which may be raised and lowered are mounted to the chassis of the vehicle. A three section telescopic boom is equipped with a tie clamping device that also has the ability to tilt a tie in relation to the boom. The boom may be pivoted about horizontal and vertical axes. The boom is mounted to the vehicle by way of a side shift carriage which allows the proximal end (i. e. , end closest to the vehicle) of the boom to be moved towards the center line of the vehicle so as to allow the vehicle to meet road clearance limitations.

A tie replacement vehicle uses a tie feed arm to turn ties upon the main frame of the vehicle upside down such that they may be gripped by a tie inserter having a boom mounted below the main frame of the vehicle. The tie inserter has a tie clamp which may be shifted in the lengthwise direction of the vehicle in order to shift old ties out of the way. A tie pickup is mounted at each end of the vehicle for moving ties from the main frame of the vehicle to the rails. A conveyor system on the vehicle allows ties to be moved under the operator cab and engine.

A rail spike feeder, which may feed regular spikes, hairpin or lock spikes, and coach screws, uses a holder which receives spikes from a spike chute. The spikes do not assume any secure position from exiting the spike chute until after contact with the holder. The holder uses a four bar linkage arrangement such that the holder pivots about ends of first and second links at the same time the opposite ends of the links are swinging or pivoting about their mounts. This maintains a proper orientation for spikes moved into a spiking position whereat a spiker head, such as a spike hammer, may insert the spikes into tie plates and ties. A counterweighted finger assembly is used to maintain spike orientation as spikes are transferred from the spike chute to the holder.

A guide wheel apparatus and vehicle typically used in railroad applications, using the apparatus has a double overcenter linkage arrangement to secure rail wheels in both road and rail positions for respectively traveling on roads and rails. An electric motor is coupled to the linkage by way of a planetary gear train.

A rail engagement apparatus to allow a highway or road vehicle to travel along a railway includes a wheel support having railway wheels. When the rail support is in a lower position corresponding to a rail mode, the wheel support bears against the underside of the vehicle axle. Vibration and shock from contact between the railway wheel and rails will therefore be dampened by the vehicle suspension. The wheel support may be disposed in an upper position corresponding to a road mode such that there is no contact between the wheel support and the vehicle axle.
