Abstract
Abstract An oil absorbent bib to be suspended under an engine for preventing oil drip, the bib comprising a first layer of wire mesh for strength, a second layer of a pad that absorbs oil and oil based fuels, a third layer of a perforated neoprene and a fourth layer of neoprene sheet that holds water not abosrbed in the second layer that may flow out between third and fourth layers. In the assembly of the bib provisions are made for adding a bib extension for extra long engines or mechanical devices that drip oil.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
126 words
A multilayer oil absorbent engine bib for installation under a mechanical device for absorbing oil drips therefrom, said engine bib comprising: a first layer of hardware cloth for providing mechanical strength to the engine bib, said first layer to be positioned facing the mechanical device and being the first layer to receive an oil drip; a second layer adjacent said first layer, said second layer formed of a material that absorbs oil and oil based fuels and rejects water, said second layer having a plurality of small spaced holes for passage of non-absorbent fluids; and a third layer of a neoprene sheet adjacent said second layer, said neoprene sheet having a plurality of small spaced holes for passage of fluids not absorbed in said second layer.
Claim 2
Dependent Claim
126 words
A multilayer oil absorbent engine bib for installation under a mechanical device for absorbing oil drips therefrom, said engine bib comprising: a first layer of hardware cloth for providing mechanical strength to the engine bib, said first layer to be positioned facing the mechanical device and being the first layer to receive an oil drip; a second layer adjacent said first layer, said second layer formed of a material that absorbs oil and oil based fuels and rejects water, said second layer having a plurality of small spaced holes for passage of non-absorbent fluids; and a third layer of a neoprene sheet adjacent said second layer, said neoprene sheet having a plurality of small spaced holes for passage of fluids not absorbed in said second layer.
Claim 3
Dependent Claim
39 words
The engine bib claimed in claim 1 wherein said first layer is larger in area than said second and third layers and extends around and under the edges of said second and third layers to secure said layers together.
Claim 4
Dependent Claim
47 words
The engine bib claimed in claim 2 further including a fourth layer of a neoprene sheet adjacent said third layer for sealing the engine bib against leakage through said fourth layer, non-absorbed fluids passing through said third layer being removed between said third and fourth neoprene sheets.
Claim 5
Dependent Claim
79 words
The engine bib claimed in claim 3 wherein said bib is rectangular in shape and wherein said four layers of said bib are secured together by rivets positioned along a plurality of spaced pairs of longitudinal rows, each of said pair of rows forming a longitudinal pocket between said third and fourth layers for slideably containing a structural member that may extend from the ends of the engine bib for lengthening said bib by attaching a second bib thereto.
