An oil-making machine

This is an oil-making machine made of iron, and oil is produced here in a proper way. It can be seen that there is a handle, and there is a space inside where materials are placed and pressed. After that, oil comes out from the bottom.

The components there help to extract the oil smoothly, which is why this machine is widely used. It works quite well. I took some photos, which I have now shared with you.
