    • 428,301. Spray carburetters. MANNERS, W. H., and CHAPMAN, W. R., 42, Main Street, Sparkbrook, Birmingham. Nov. 20, 1933, No. 32227. [Class 7 (iii)] In a carburetter in which interconnected valves control an air inlet and a mixture outlet, disposed at opposite ends of a body portion, and a variable fuel nozzle between them, the air inlet and mixture outlet are disposed at right angles to the flow of mixture through the body and their valves move longitudinally therein or thereon. A barrel throttle valve 13 and a sliding air valve 6 adjustably connected together by rods 22 control respectively the outlet of mixture and inlet of air to a cylindrical casing 1 having diametrically across it a fuel nozzle 32 provided with a discharge orifice 36. A rotatable sleeve 7 within the casing determines the maximum size of the air inlet port 4, and may close it for starting. One side of the port 4 is curved to ensure a proper air-fuel ratio at all throttle openings. The throttle valve 13 works in a sleeve 25 having oppositely arranged openings 29, 30 governing the maximum throttle opening and the admission of secondary air through a port 31 in the casing 1. The air valve 6 is coupled to a plate 43 mounted on the rods 22 and provided with holes 47 for the reception of two pins 42. These pins engage levers 40, 38 mounted respectively on a sleeve 37 screwed on the top of the nozzle tube 32 and an outer sleeve 39 screwed, with an opposite thread, on the sleeve 37. The sleeve 39 supports the fuel needle valve which is lifted by the operation of the threaded sleeves when the levers 38, 40 are rotated by movement of the plate 43. An eccentric may be associated with the air inlet sleeve 7 to displace the plate 43 and provide additional fuel at starting.

    • 1,045,904. Outboard propelled craft with ski members. W. R. CHAPMAN. Aug. 4, 1964 [July 16, 1963], No. 30573/64. Headings B7A and B7V. A catamaran comprises a pontoon member 12 (Figs. not shown), a crossboard 18, said crossboard having attached to its ends ski members 14, 16, a pair of foot pockets 58 positioned on said crossboard on either side of the pontoon member, motor means 22 carried by the pontoon member and handle means 24 secured to the motor,said handle means including a handle portion 132 disposed for gripping when the operator stands in the pockets 58. As shown, when in position, the operator stands with his feet in pockets 58, inside a loop formed by the handle 132. The handle when moved, rotates the outboard motor for steering purposes when the craft is running at slow speeds. When running at fast speeds the pontoon member 12 planes and sinks at the stern, bringing the skis 14, 16 into contact with the water. Steering at high speeds is effected by the operator transfering his weight to the appropriate side of the pontoon A receptacle 140 for receiving a fuel container 142 is positioned on the crossboard.
