Abstract
Abstract A device and method for covering pilings of piers and the like includes a plastic cover or sheet which is wrapped around the piling for protecting the piling against rot, weather and wear. The plastic sheet ends overlap as they wrap around the pile. The ends are sealed and secured by a heatable strip extending between the overlapped ends of the sheet and which forms a fused plastic seam between the overlapped ends as the sheet is held tightly about the pile. A strap and a bar which presses over the heatable strip is provided for temporarily cinching the plastic sheet tightly about the pile and holding it while the heat fusing occurs.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
98 words
A method of covering a pile with a plastic material comprising: extending a plastic sheet having first and second ends around a pile such that said first end overlaps said second end and a strip heatable by electrical resistance heating extends therebetween; sliding said first end over said second end until said plastic sheet is tightly cinched around said pile; and, after said extending and sliding steps applying an electric current to said heatable strip so as to fuse and seal by electrical resistance said first end to said second end forming a fused, tightly wrapped pile cover.
Claim 2
Independent Claim
98 words
A method of covering a pile with a plastic material comprising: extending a plastic sheet having first and second ends around a pile such that said first end overlaps said second end and a strip heatable by electrical resistance heating extends therebetween; sliding said first end over said second end until said plastic sheet is tightly cinched around said pile; and, after said extending and sliding steps applying an electric current to said heatable strip so as to fuse and seal by electrical resistance said first end to said second end forming a fused, tightly wrapped pile cover.
Claim 3
Dependent Claim
98 words
The method of claim 1 wherein said sliding step comprises: connecting a bar to said first end of said plastic sheet so as to retain said end as said bar is moved and so as to reside over said heatable strip between said first and second ends; connecting a tightenable strap to said bar about said pile and sheet; and tightening said strap so as to pull said first end of said sheet over said second end of said sheet and so as to urge said bar to press said heatable strip between said first and second ends.
