Connectors are often used to connect a cable held on a vehicle such as a truck, to circuitry that does not move with the truck, such as a circuit on a stationary facility. Occasionally, the vehicle is accidently driven away while the connectors are fully mated, resulting in breakage at some weakest location and possible damage due to overstress at other locations. The parts that are broken apart or damaged may be located where there is large cost and delay in repair. A break-away apparatus that resulted in a break at a location that could be repaired at minimal cost and with little downtime for the equipment, would be of value.

I agree with Ryan. Although i don’t know what he’s speaking of…Hooah!

It’s called a Flexture. It can handle loaded axially by can be bent a small amount to take into account small angular misalignments. I have seen them used in vibration and shock environmental test. A large test object is brought in and “isolated” on either large springs or airbags. At some point it is attached to a vibration exciter (shaker table or some other device) using the flexture. The flexture lets the unit under test bounces around a bit without putting large moments on the fragile vibration armature. Generally there are not huge loads going through the flexture but they usually attach at a load path which may have large bolt holes. The shakers generally have a standard bolt pattern (5/16 i think or maybe 1/2″) So the small side probably screwed into the shaker head with a lock nut to tighten it. The other side would do the same into whatever it was that needed testing. The rust also indicates that it was an environmental test. As they vibrate a test object they will also raise and lower the temperature and humidity. Flextures are normally made out of some springy steal that isn’t very good at corrosion.

Oh this one is so simple. It’s a bolt!

Its for some sort of scaffolding. The fat part goes into the top of the tube and the skinny part goes into the bottom of the next vertical tube. The nut is for leveling adjustment/locking. The cupped parts are at 90 degrees and thats where the horizontal poles are attached.

Just my guess. I have no idea of it name.

its some type of counter screw to stick in a drain basket, to help you unscrew the lock nut on the other side of a kitchen sink?

Maybe a steam valve for a double-acting steam engine? As it rotates, it directs steam in one side while venting the exhaust out the other. Rotate the valve 90 degrees and it repeats on the other side of the cylinder.

Toolaremia Says: “It’s the gozinta bolt for a harmonic fractilator. Typically the full-capacity fractilator.”

PUH-LEEZ! Look at the canting on the shroud manifold. Clearly that for a 3/4 capacity fractilator.

This looks like an internal 90 degree joiner bolt for railings or catwalks. It fits in a sleeve that has matching hole patterns and is locked down by the top nut/bolt. Just a guess.

Is is the radial-bore support for the cleaning mechanism of a rusty-trumpet?

Something scaffholding-related? Like a Kee Clamp, for holding tubing (with some missing bracketry). Just guessing.
