Launch Control
As a kid in the '50s, there was a sand bank on the crest of a hill, at the side of the road, far to the north. Ice age sand, perfectly clean, about forty feet high. Tobogganing down on corrugated cardboard packing boxes from the grocery store, because we could fit in the boxes. Great mems. A happy place.[This message has been edited by Valkrie9 (edited 03-11-2023).]

The jumping bull... That 'little dog' is a blue heeler (sometimes called an Australian cow dog) and heelers are named that for a reason. Nice gentle friendly dogs until their owner gives them an order and they turn into a buzz saw. Agility and quickness wins out over bigger opponents. Cattle, sheep, bigger heavier dogs are no match for them.
The double hinge gates have been around for a long time out in the Southwestern US and other places. In open range counties and states , there were 'bump gates' where a car (back when cars had real front bumpers) would drive up to a closed gate, bump the gate and it could be pushed open by the vehicle and it worked same going either direction because of that type hinge. I was around 13-14 first time I saw one.[This message has been edited by maryjane (edited 08-21-2022).]

Don, I'm quite curious what the top hinge looks like... because it's gotta be different than the bottom one!

Same as the bottom but the pins each have a flat flange welded on top of them...like a big washer, and most importantly, a support cable that runs diagonally from the top corner at the far end of the gate , up to a tall pole the hinge support is on. It's this cable and it's precise length that allows (forces) the gate to swing back to a closed position eah time it is opened.
In some cases, the top part is inverted, pins facing downward to prevent livestock from just putting their heads under the gate and lifting it off the pins. They don't work well for a gate that is operated (opened/closed) frequently, as the plate under the bottom hinge wears[This message has been edited by maryjane (edited 08-22-2022).]

Ah, that's the (previously) untold secret... a support cable! I knew there had to be something to keep the gate from simply tipping downwards and falling off the top hinge!
Thanks Don.

it also might have a helper wheel on the other end too.
