Abstract: A camera dolly has a track wheel system including a kingpin pivotally supported on a dolly chassis. A kingpin tube extends laterally from the kingpin. An axle is pivotally supported within the tube on pins. A track wheel around a bearing is supported on a bushing on the axle. A knob unit threaded into the axle may be turned into a locked position wherein the track wheel is supported as in a conventional axle. For use on curved track, the knob unit is released or backed out, allowing the track wheel to shift laterally, to accommodate moving on curved dolly track, and to allow the wheel to steer on the track at a proper steering angle, by pivoting on the pins.

Abstract: A railway axle assembly with orientable wheels (8) is compensated in width when passing on a railway track curve. The assembly comprises side beams (5,5') articulated to the opposing ends of a telescoping axle (4). The side beams (5,5') are coupled to each other by at least one connecting rod device comprised of at least one broken rod (13) hinged at a breaking point to a lever-relay (15,25) carried by the axle (4) so as to entrain the breaking point in an angular displacement of an arc of a circle in a direction opposite to that of the beams (5,5') in order to compensate for the width loss of the axle when taking curves.

Abstract: A variable wheel-spacing truck includes a pair of left and right bogie frames which are transversely movable relative to each other and can be fixedly connected with each other by releasable locking devices. At least one of the wheels is slidable relative to the wheel shaft in an axial direction of the shaft. When the truck moves from one railway onto a junction railway of a different track gauge, running paths push auxiliary wheels of the locking devices upwards to release the locking devices. When the truck moves through the junction railway section, a pair of guide rails or a pair of rails push the wheels of the truck, thereby laterally shifting the left and right bogie frames relative to each other. After a predetermined relative transverse movement of the bogie frames and wheels is completed, the running paths lower the auxiliary wheels of the locking devices, thereby activating the locking devices into a locking condition.

Abstract: A variable wheel-spacing truck is equipped with axle boxes slidably mounted on axles extending between side beams of a bogie frame. Axle box receivers are selectively and releasably connected with the axle boxes at a plurality of predetermined positions by locking members. When the truck is moved from a first railway to a junction railway, auxiliary wheels mounted on the axle box receivers engage with running paths and raise the truck and a vehicle body except the wheel sets and release a locked condition by the locking members. When the truck is moved through a region where the track gauge of the junction railway is changing or where the spacings of inside or outside guide rails is changing, the wheels are pushed by a pair of guide rails or a pair of junction railway rails and shifted transversely together with the axle boxes relative to the axle.
