A flexible gate is disclosed which comprises a plurality of segments. The segments may be connected by at least one coupling. When the flexible gate is acted on by a force, the flexible gate may flex. When the force is no longer present, the flexible gate may return to a substantially straight position. The segments may be removed or added as needed to repair broken segments or to adjust the length of the flexible gate.

A railway switch stand includes a housing with a vertical shaft having a lower end connected to the switch throw rod, the shaft being rotatable to reciprocate the throw rod. A plate is mounted orthogonally on the shaft for rotation with the shaft, and has a plurality of bearings projecting upwardly therefrom around the shaft. A cam follower is mounted to move along a circle with the same radius as the bearings, with a spring mounted above the cam follower to apply a downward biasing force on the cam follower to retain the cam follower between a pair of bearings. A motor has a drive shaft oriented orthogonal to the vertical shaft and includes a drive crank affixed orthogonally to the drive shaft with radially projecting ends. One end of the crank is connected to a U-shaped yoke which in turn is pivotally connected to the cam follower. The other end of the crank has a counterweight, such that the crank will rotate the vertical shaft approximately one-quarter turn upon rotation of the crank approximately one-half turn on the drive shaft.

An adjustable level having an angled base with legs extending normal to one another from a common edge and with magnets spaced along and extending fully through each leg; an L-shaped bracket having at least one bubble housing fixed to a leg thereof; a post extending from the base and through a hole in the bracket; a spring on the post and between a head on the post and the bracket to bias the bracket towards the base and to thereby engage ribs on the bracket into grooves on the base; and a retainer for retaining the level to objects, including a flexible cord connected to a return spring and a loop and hook to secure the cord in a pulled out condition surrounding an object.
