This is anoriginal feature and evidently makes it possible to combinehigh piston speed with a moderate speed of revolution,both of which are desirable, the first, because it resultsin high power per unit of displacement and in the highthermal efficiency and the second, because it reduces thestrain due to centrifugal force on the engine structure. Poppet valves are not very suitable for use in a revolvingengine, owing to the effect of centrifugal force on theiroperation. In the engine here described a single sleevetype of valve is employed which has a combined rockingand reciprocating motion. Referring to the accompanying sectional view, the wholeengine is supported on a stationary hollow shaft, the for-ward end of which is held rigidly on a cross member ofthe frame. Combustible charge enters this hollow shaft atforward end and flows through ports in wall into a pas-sage leading to the cylinder inlet ports, the opening andclosing of which are controlled by the single sleeve Ncdomn Mnjdcr rerolfhiy air-rimlcd irohhlinr/ pinto engine 220 AUTOMOTIVE INDUSTRIESTHE AUTOMOBILE February S, 1921 The five cylinders, which have a bore of 2% and a strokeof 3% in., are cast of aluminum with the cooling ribsintegral. Into the outer ends of these cylinders are fittedcylinder heads of a form similar to those used in Knightengines, there being an annular space between the cylinderhead and the cylinder wall into which the sleeve spark plugs are located centrally in the cylinder valve sleeves are made of cast iron and the pistonswithin them of aluminum. The connecting rods are tubu-lar, with spherical heads, which are fitted respectively intothe piston and into sockets of the wobbling disk. Thewobbling disk is held against rotary motion relative to thecylinders by a guide secured to the engine housing andextending through a slot of the disk. The disk is sup-ported on two ball bearings mounted upon a hub surround-ing the stat
