Abstract
A gasket for internal combustions is held together by form-locks that do not extend beyond the outer surfaces of the gasket. The form-locks are established in regions where some of the sheets of the gasket do not extend and thus do not incorporate the thickness of those sheets, yet all of the gasket sheets are securely joined.

A gasket for an internal combustion engine, comprising:
- first and second metallic sheets each having an outer surface, an inner surface, and at least one opening formed therein,
- at least one inner sheet disposed between the inner surfaces of the first and second metal sheets, the inner sheet having at least one opening formed therein,
- said openings being aligned to form an aperture in the gasket, and
- a form-lock joining two of the sheets at the aperture,
- wherein the form-lock is disposed entirely within the planes defined by the outer surfaces of the first and second metal sheets.
A gasket for an internal combustion engine, comprising:
- first and second metal sheets each having an outer surface, an inner surface, and first and second openings formed therein,
- at least one inner sheet disposed between the inner surfaces of the first and second metal sheets, the inner sheet having first and second openings formed therein,
- said first openings being aligned to form a first aperture in the gasket,
- said second openings being aligned to form a second aperture in the gasket,
- a first form-lock joining the first metal sheet and the inner sheet at the first aperture, and
- a second form-lock joining the second metal sheet and the inner sheet at the second aperture.
A method of forming a gasket for an internal combustion engine, comprising:
- providing first and second metal sheets each having at least one opening formed therein,
- providing at least one inner sheet having at least one opening formed therein,
- disposing the inner sheet between the first and second metal sheets,
- aligning said openings to form an aperture in the gasket, and
- joining two of the sheets in a form-lock at the aperture in a manner whereby the form-lock is disposed entirely within planes defined by outer surfaces of the first and second metal sheets.
A method of forming a gasket for an internal combustion engine, comprising:
- providing first and second metal sheets each having at least first and second openings formed therein,
- providing at least one inner sheet having at least first and second openings formed therein,
- disposing the inner sheet between the first and second metal sheets,
- respectively aligning said openings to form first and second apertures in the gasket,
- joining the first metal sheet and the inner sheet at the first aperture, and
- joining the inner sheet and the second metal sheet at the second aperture.
A gasket for an internal combustion engine, comprising:
- at least three sheets arranged in a laminate fashion,
- a plurality of apertures formed of aligned openings in the sheets, and
- a plurality of form-locks joining said sheets at the apertures,
- each of said form-locks joining fewer than all the sheets,
- said form-locks being so distributed that each of the sheets is joined by at least one of said form-locks to each adjacent one of the sheets.
