Patent ID: 7740059

Claim:
A device for perforating a well casing, comprising: a frame adapted to be inserted within said well casing and move in a direction parallel to a central longitudinal axis of said well casing; a lower perforator pivotally connected to said frame; wherein said lower perforator includes a plurality of spikes extending therefrom for engagement with said well casing; an upper perforator pivotally connected to said frame; wherein said upper perforator includes a plurality of spikes extending therefrom for engagement with said well casing; a lower spring connected to said frame on a first end and mechanically connected to said lower perforator and said upper perforator on a second end; wherein said lower spring imparts a pivotal downward force upon said lower perforator and said upper perforator so that said plurality of spikes of said lower perforator and said upper perforator automatically grab said well casing and pivot through said well casing with a change in directional movement of said frame; and an upper spring connected to said frame on a first end and mechanically connected to said lower perforator and said upper perforator on a second end; wherein said upper spring imparts a pivotal upward force upon said lower perforator and said upper perforator so that said plurality of spikes of said lower perforator and said upper perforator automatically grab said well casing and pivot through said well casing with a change in directional movement of said frame.
