Shaw, T M

In an internal combustion engine, a cylinder block is described having a cylinder head removably secured thereto by restraining bolts, the block comprising a cooling jacket having interconnected opposing load-bearing side and end walls and a floor section; a cylinder tube portion located substantially within the cooling jacket and comprising a plurality of relatively spaced substantially free-standing cylinder tubes supported by and perforating the floor section. The tubes, side walls, end walls and floor section are adapted to coact with the cylinder head to form a cavity through which a coolant is adapted to circulate; an elongated reinforcing rib disposed outside the cavity, the rib integral with and projecting downwardly from the floor section and having at least a portion thereof extending intermediate adjacent cylinder tubes. The portion has a lowermost free edge; means for receiving the restraining bolts and being positioned relative to the cylinder tubes for providing substantially uniform perimetrical support of the tubes when the restraining bolts are tightened to secure the head to the block; and means for substantially restricting radial movement of the upper portion of the cylinder tubes, the movement restricting means comprising elongated struts substantially radially extending from the cylinder tubes and connected to predetermined walls of the cooling jacket.
