Abstract
Abstract A combination breather cap and oil can piercer device for use on automotive engines for replacement of existing breather caps. A collapsible sleeve and plate attached thereto guide a manually held oil can into opening contact with a stationary piercer element normally shrouded by the extended sleeve. Closure means normally seals the lower end of the tubular piercer element to prevent engine entry of foreign objects while a removable cap closes off the internal sleeve area to prevent the deposit of dirt particles on the can piercing element. Normal breather cap functions are provided for which may include directing crankcase vapors into the fuel-air intake system.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
189 words
A combination breather cap and oil can piercer device for use on an automotive engine, said device comprising, a base includung mounting means removably engageable with an engine component, said base adapted to permit passage of engine produced vapors, a plate outwardly spaced from said base and including means for positioning an oil can thereon, said plate apertured at its center, a collapsible sleeve interposed between said base and said plate including means biasing said plate away from the base, a tubular can piercing element centrally mounted on said base and normally concealed within said sleeve when the latter is in its extended position, closure means for said piercing element adapted for opening movement during the collapsing of said sleeve permitting the passage of oil therepast while at other times serving to close off the lower end of said tubular piercing element, and said device permitting the opening and addition of canned oil to an engine upon placement of the can on said plate with subsequently exerted downward force causing said sleeve to collapse with resultant can piercing contact of the piercing element and opening of said closure means.
