Abstract
An ice fishing tip-up includes a base frame adapted to span a hole in a layer of ice over a body of water, and carrying a mast which is extendible through the hole into the water. The mast includes a shaft fixed at its lower end to a spool of fishing line and at its upper end to a cam cylinder with a helical groove formed in its outer surface. A signal staff is spring-biased to a raised position and is movable to a lowered position received in one of the convolutions of the helical groove. A pull on the fishing line rotates the cam until the staff reaches the end of the helical groove, releasing it to its raised position, the amount of pull required to trip the staff being adjustable with the cam groove convolution in which it is retained.
