Abstract
435,487. Valve gear; casings. SLATER, R., 2, Avenue de LutÞce, La Garenne, Seine, France. March 24, 1934, No. 9246. [Classes 7 (ii) and 7 (vi)] In engines having overhead valves, the valveoperating mechanism lying above or adjacent the valves is carried by means pivotally connected to the engine about an axis located, in the case of an overhead cam shaft, coaxial with a cam-shaft driving-member whose axis is parallel to the cam shaft Or cylinder axis, or, in the case of push-rods actuated by remote cams, located in line with the joints between the push rods and cam rockers or tappets. Fig. 4 shows an overhead cam shaft 22 which is driven by bevel gear 24, 25 from a vertical shaft and is supported in a housing 4 which may be swung aside, as shown, about the axis of the vertical shaft. When in position over the valves 3, the housing 4 is secured to the cylinder head by bolts 14. One side of the housing is detachable to allow the housing to be swung without being obstructed by the valves. In another form, in which the cam shaft is driven by a chain, the cam shaft housing is secured to the chain housing, and both swung aside about the axis of the lower chain sprocket. Fig. 12 shows another form in which the valves are actuated through push rods 38 and rockets 35, all carried by a housing 4 pivoted at 59 for swinging aside as shown. The pivoted housing may carry engine auxiliaries. Cylinder pipes and passages.-Down-draught carburetters may be attached to flanges 52, Fig. 4, on the housing 4, inlet passages 60 therefrom leading to openings 60<1> formed in the cylinder head and connected with inlet passages 53.
