Abstract: A one piece, panel-like and generally diametric blade is mounted upon one end of a shaft portion for rotation therewith. The blade is generally S-shaped in configuration as viewed along the center axis of the shaft portion and includes a pair of inner and outer cutting blade edges extending along each of the wing portions of the blade disposed on opposite sides of the shaft portion. The inner ends of the inner cutting blade edges terminate a spaced distance outwardly of the center axis of the shaft portion, the inner and outer cutting blade edges are each outwardly inclined away from the axial direction of the shaft portion in which the blade edges face.

Abstract: A fishing tip-up utilizes a rocker arm which is pivotally mounted to a body member for oscillation about a horizontal axis to effect an up and down jigging movement of a hook and bait on a line associated with the arm so as to attract fish. The oscillation of the arm is accomplished through the use of a wind vane attached to the arm which serves to cause a movement of the arm in response to air movement coming into contact with the vane. An adjustable spring is operably attached to the pivotal arm so as to assist the wind vane in creating the up and down movement, and a tip-up flag assembly is provided to signal a remotely-located fisherman that a fish has taken the bait. The fishing line is wound on a spool journaled on the arm with the spool including an adjustable friction brake structure and the line extends through an aperture in the vane.

Abstract: A signalling device for use when ice fishing which includes a flag that is retained in a generally horizontal retracted position when the device is set for use and moved to an upright signalling position when the fish takes the hook and pulls fishing line from a reel. The device also includes a frame supported on the ice in transverse relation to an ice hole in which the frame includes a unique structure which enables it to be easily lifted from the ice even if it is placed on the ice surface when the surface is somewhat slushy and becomes frozen to the ice thereby facilitating the fisherman pulling out a fish or removal of the device when it is desired to leave the fishing area.
