A method of manufacturing an engine block assembly which includes a one-piece cylinder block and cylinder head member including a cylinder block portion having a cylindrical bore with an inner end, and a cylinder head portion including a cylinder head surface at the inner end of the cylindrical bore, and a sleeve in the cylindrical bore and including an inner cylindrical surface engaging the cylinder head surface at the inner end of the cylindrical bore, the method includes the steps of fabricating a one piece cylinder head and cylinder block member including a cylindrical bore having, at the inner end thereof, a cylinder head surface, fabricating a sleeve with an inner cylindrical surface and an inner end, partially inserting the sleeve into the cylindrical bore such that the inner end of the sleeve is spaced from the cylinder head surface, boring the inner cylindrical surface of the sleeve, honing the inner cylindrical surface of the sleeve, and fully inserting the sleeve into the cylindrical bore such that the inner end of the sleeve engages the cylinder head surface.

Method of inserting, boring, and honing a cylinder bore liner

A variably unbalanced rotating mechanism comprising a frame, a main shaft having a longitudinal axis and supported on the frame for rotation about the longitudinal axis, a drive for rotating the main shaft, first and second eccentric weights mounted for rotation coaxially with the main shaft, and a mechanism for rotating the weights in common with the main shaft and for selectively rotating the weights in opposite directions relative to each other and relative to the main shaft and independently of main shaft rotation.

Shaking apparatus

A molding apparatus comprising a rigid mold flask adapted to contain a mold pattern and sand, and when containing sand, having a combined center of gravity, a support for resiliently supporting the mold flask for horizontal movement only of the mold flask as a whole body, and a vibrator for shaking the mold flask to provide horizontal vibrational forces directed in a horizontal plane extending approximately through the combined center of gravity.

Molding apparatus and process including sand compaction system

A mold pattern is held in position in a mold flask in an unconnected relation to the mold flask. Sand is supplied to the mold flask to surround the mold pattern while the mold flask is vibrated to compact the sand around the mold pattern.
