Abstract

254,052. Lord, A. O. May 8, 1925. Cylinders, valve claests and covers for, passages of, and arrangement of igniters in.-A cylinder head for an overhead valve engine comprises a one piece casting having two outwardly extending casings g carrying cam-shafts s at their extremities. Bearing blocks o are mounted in notches in webs in the casings g and covers g<1> are secured to bearing caps b'. The cam shafts may be driven by chain gearing as described in Specification 248,961, [Class 7 (vi), Internal-combustion engines, Valves &c. for]. The valves i, e are arranged at 45‹ to the cylinder axis, and the sparking plug p are placed in recesses in the trough t between the casing g and may be arranged out of the plane of the valves i, e. The inlet and exhaust passages k l are arc-shaped. The invention is (particularly applicable to small multi-cylinder engines.
