Hi, restore49.
Those 'gadgets' were the ancestors of logging arches back before there was mechanical horsepower and logging was done with horse or bullock teams. They were a way of getting the front end of the log off the ground for easier pulling - went the way of the dodo bird and the dinosaurs when powered winches on tractors became a thing and logging arches became possible.
