Meaning of futre by Marco Moreno

When I was a girl, in the country in Chile where my mother lived, there were tremendous oak barrels of highs, wider than above. They had a ladder stuck to one side. They were on top of some kind of platform. These barrels had in the center a vertical piece of metal, threaded. As the harvest progressed, it was filled with grapes. When it was almost full, he put a wooden lid that curled into that piece of metal and crushed the grape inside the futre. I don't remember the mechanism for screwing the lid, as it was a very large lid. It was surely a manual-mechanical mechanism as there was no electricity, but as it was made at the top of the futre, and we were children, we could not see well. The juice is output by one of the lower side openings. In it was put one as a wooden key. This barrel was called futre. They were also used in threshing season, filled with wheat and in the other lower outlet, a little higher than that of the harvest, came the wheat that was filling the sacks that the workers held down. For that there was a base of a shovel that was threaded into the central iron and when moving it was pushing the wheat around, to facilitate the filling of the sacks. We loved getting on the futre when it was full of wheat, it was like a pool that instead of water had wheat grains.
