Abstract
412,481. Cooling cylinders. PRESTWICH, J. A., 28, Canfield Gardens, Kilburn, London. Nov. 11, 1933, No. 31494. [Class 7 (ii).] Radiating ribs b of an air-cooled cylinder are connected at intervals near their peripheries by extensions c cast integral with them ; the natural frequency of the unsupported parts of the ribs is thus raised above the limit of audio frequency and the tendency of the ribs to vibrate owing to engine noises is reduced. For casting, the mould is formed by inserting a series of rods in the pattern, which rods are withdrawn after the sand has been rammed and before the pattern is removed.
