Ice fishing tipup

Claim 2

In a tipup for fishing through a hole in ice, float means, a source of heat, means for applying the heat from the heat source to the float means to generally prevent the water in the fishing hole from freezing over, a vertically extending tubular member supported by the float means and projecting above and beneath the float means, a shaft rotatably disposed generally centrally of the tubular member, a fishing line spool carried on the lower end of the shaft beneath said tubular member and being rotatable with the shaft to play out fishing line, a trip lever carried at the upper end of the shaft above the tubular member and being rotatable with the shaft, and means provided on the tubular member and engageable with the trip lever to interrupt rotation of the trip lever, shaft and line spool and thereby set the fishing depth for the fishing line, said means engageable with the trip lever being releasable from said lever in response to the playing out of fishing line and rotation of the line spool as when a fish runs with the fishing line.

Claim 3

The structure as set forth in claim 1 wherein the float means comprises a bowl-like member and the tubular member is disposed generally centrally of the bowl-like member and is sealingly connected thereto, said bowl-like member being adapted to contain combustible material and serving as a heat source to generate heat upon ignition to generally prevent the fishing hole from freezing over.

Claim 4

The structure as set forth in claim 2 wherein a cover is provided for the bowl-like member, said cover being provided with a hole centrally thereof to pass over the releasable means engageable with the trip lever in its released condition, and the trip lever and the tubular member, said hole being sufficiently large to provide air for combustion when the cover is seated on the bowl-like member.

Claim 5

The structure as set forth in claim 3 wherein spring means serve to clamp the cover down onto the lip of the bowl-like member.

Claim 6

In a tipup for fishing through a hole in ice, a bowl-like member floatable on the water in the hole, a vertically extending tubular member disposed generally centrally of the bowl-like member and projecting above and beneath the bowl-like member and being sealingly connected to the bowl-like member, a shaft rotatably disposed generally centrally of the tubular member and projecting beyond the respective ends of the tubular member, a fishing line spool carried on the lower end of the shaft and being rotatable with the shaft to play out fishing line, a trip lever carried at the upper end of the shaft and being rotatable with the shaft, and signal means mounted on the tubular member and being releasably engageable with the trip lever, said signal means serving to interrupt rotation of the trip lever and shaft and line spool and thereby set the fishing depth for the fishing line when engaged with the trip lever and being releasable from the trip lever with rotation of the shaft to indicate the playing out of fishing line, said bowl-like member containing a combustible material to generate heat upon ignition to generally prevent the fishing hole from freezing over.

Claim 7

In a tipup for fishing through a hole in ice, a bowl-like member floatable on the water in the hole, a vertically extending tubular member disposed generally centrally of the bowl-like member and projecting above and beneath the bowl-like member and being sealingly connected to the bowl-like member, a shaft rotatably disposed generally centrally of the tubular member and projecting beyond the respective ends of the tubular member, a fishing line spool carried on the lower end of the shaft and being rotatable with the shaft to play out fishing line, a trip lever carried at the upper end of the shaft and being rotatable with the shaft, and signal means mounted on the tubular member and being releasably engageable with the trip lever, said signal means serving to interrupt rotation of the trip lever and shaft and line spool and thereby set the fishing depth for the fishing line when engaged with the trip lever and being releasable from the trip lever with rotation of the shaft to indicate the playing out of fishing line, said bowl-like member containing a combustible material to generate heat upon ignition to generally prevent the fishing hole from freezing over.

Claim 8

The structure as set forth in claim 5 wherein a cover is provided for the bowl-like member, said cover being provided with a hole centrally thereof sufficiently large to pass over the signal means in its released condition and the trip lever and the tubular member and to provide air for combustion when seated on the bowl-like member.

Claim 9

The structure as set forth in claim 6 wherein releasable spring means extend between the cover and the bowl-like member and serve to clamp the cover down onto the lip of the bowl-like member.
