Abstract: A guy yoke for use in a guyed structure terminate two support guys coupled to said structure and to transfer loads entered on said supported guys to anchor means, said guy yokes includes two arms pivotally coupled to an anchor plate at one end and coupled to guy wires at the other end. A spreader arm is coupled to the arms to maintain them in a fixed position for forces transmitted by the guy lines which are below a predetermined level. The spreader arm is coupled to the two arms by shear bolts or pins. When the forces transmitted to the yoke are at or exceed the predetermined level, one or both of the shear bolts or pins is severed permitting the two arms to swing toward each other and thereby add effective length to the guying.

Abstract: A device is described which operates as a "mechanical fuse" in a guy arrangement such that when loading forces on the guyed structure exceed a predetermined level, the device will add length to the guy arrangement. The device includes two plates coupled by a hinge bolt and a shear bolt. When the force exceeds the predetermined level, the shear bolt is severed by the plates allowing the plates to "scissors" open about the hinge bolt.

Abstract: A lightweight ladder includes a vertical member of flat sided tubing, rungs formed of angle metal, and ladder feet adapted to engage retaining clips mounted on a vertical structure. The ladder feed are designed to provide wedging between the clips and the vertical structure such that set screws are not required to keep the ladder in place and stable.

Abstract: A pole includes a lower tubular steel section having a multi-sided wall. A diaphragm is disposed at a predetermined height within said lower section, and cooperates with the wall of the lower section to form a chamber for receiving a wooden upper pole section.
