Which of the following most accurately describes the problem?

FUR many years copper and asbestos gaskets have been used to form joints between cylinder blocks and cylinder heads and to make watertight connections. These have been satisfactory in many cases, but where the duty of the joint is of a particularly arduous nature some conventional patterns have been known to disintegrate.

Coopers Mechanical Joints, Ltd., Manor Works, 88i, Lower Kennington Lane, London, S.E.11, has produced

special gaskets of copper, or copper and asbestos, to withstand modern conditions. Among the types listed are reinforced gaskets in which the overlap joint is strengthened by an extra copper sheet about 5 mm. wide; a second pattern has a double overlap joint. Yet another type has a plain overlap and a U-shaped strip inserted at the end where the joint occurs, thus providing a double wall of copper around the combustion space and two extra thick

mecca of copper where the greatest pressure is required between the cylinder head and the block.

For cases where plain copper gaskets are required these may be obtained in standard or reinforced patterns ; a more ductile design is the laminated copper variety; the gas seal is made by the bottom layer of copper, which is used to clip together the laminations. The water seal is made on the outside edge of the gasket by the same means.
