Abstract: 343,063. Spray carburetters. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(Moore Inventions Corporation; Slater Building, Worcester, Massachusetts, U.S.A.) Aug. 7, 1929, No. 24108. [Classes 7 (ii) and 7 (iii).] Fuel is introduced into the air stream on the engine side of the main throttle valve and the amount of fuel is controlled, directly or indirectly, by the pressure of the engine exhaust gas ; the fuel is lifted from a low-level tank and atomized by injector action of gas supplied from the combustion chambers. The gas is lead by a pipe 48 to a nozzle 28 which discharges at 32 into a choke tube 24 ; the suction thus produced draws liquid fuel up an annular passage 34 which is connected by a pipe line 60, 56, containing a liquid seal, to the fuel tank ; in the pipe line is included a gauze filter 74, and a needle valve 76 which is connected by a universal joint 80, to a large bellows 72 which is vented to atmosphere, or connected by a pipe 84, chamber 86, and pipe 90, to the carburetter air inlet adjacent the throttle valve 10. The exterior of the bellows is subjected to the exhaust gas pressure by connecting a chamber 70, in which it is mounted, by a pipe 96, containing a restriction 102, Fig. 1, and an enlargement 100 greater in volume than the space around the bellows, to the exhaust pipe 98 between the engine and the silencer; a spring 104, Fig. 3, modulates the effect of high exhaust pressure, play 107 putting it out of action at low pressure. Manual control of the fuel valve comprises a cam 108, having adjustable stops 114, 116, Fig. 4, and operated by a lever 119 either independently of, or conjointly with, the throttle valve lever 117, a shoulder 118a enabling the lever 117 to continue its motion after the cam 108 and the stop 116 are in contact. At small throttle openings, to reduce the fuel supply, the fuel is aerated in a chamber 64, Fig. 3, by air admitted through a passage 120 which is closed as the throttle is opened. When the engine is idling, a port 134 in the throttle valve provides the main air supply, and Fig. 6 shows a method of reducing the fuel supply; at starting a switch 146, preferably operated in conjunction with the ignition switch, is closed, and after the engine has warmed up the movement of the throttle lever 117 to its closed position closes a switch 148 and causes a solenoid 136 to be energized, and to attract an armature 140 on the bellows. Vaporizers, external.-A heating element in the induction manifold comprises a conical shell 75, Fig. 1, having heat radiating vanes and exhaust gas circulating pipes 75a, 75b. Specification 343,064 is referred to. Cylinders adapted to supply gas.-Cylinder gases are tapped by adjustable ball valves 40 and led through a manifold 42, piping 46,48 and a centrifugal separator 44 to the carburetter.

Abstract: 403,914. Rotary engines. KEMPTHORNE, J. L., 78, Hawthorne Place, Montclair, New Jersey, U.S.A. Sept. 2, 1933, No. 24422. [Class 110 (ii).] The capacity of a rotary engine or pump having a rotor 38, forming a segment of a sphere and an inclined abutment wall 38b, is varied by tilting the member 39 so that the wall 38b moves towards the vertical position. A sealing strip 47, which extends diametrically across the hemispherical working chamber, rotates with the rotor to pump fluid entering at a port 29 and leaving through a similar port. The square end of the driving shaft 33 fits into an elongated slot 41 in the rotor 38 so that the face 38a of the rotor may approach the abutment face. In a modification the abutment is formed by a plate screwed to the casing 30, and contains the inlet and delivery ports. In a further arrangement a rotating plate is secured to the sealing strip and ports in the plate co-operate with channels in the abutment which communicate with inlet and outlet ports. Fig. 12 shows a construction having the shaft 82 extended through the casing 70 to be coupled to another motor or pump shaft 85 by means of a key 84. The sealing strip 80 is circular and contacts partly within a rotating abutment disc 75 which contains ports 91, 92, leading to outlet and inlet ports 90, 89. Thrust bearings and collars on the shafts are provided. The ports in the abutment ring may be used as cut-offs, especially where steam is used to drive the rotor. Where several units are connected in alignment, the starting angles of the rotors may be different, to secure an even torque. In Fig. 13 rotating plates 117 divide a spherical space into two working chambers, wherein segmental rotors 118, 118a operate. Packing rings 125, 126, 127, are provided, and may be spring-pressed as by springs 127a. The shaft 113 has a polygonalshaped driving section extending through the centre 121. A spring 132 presses against a collar on the shaft. Intake ports 128 are furnished and the exhaust takes place through conduits 129 controlled by reed valves 130. The segments 118, 118a may be of different sizes and the two working chambers form two stages of a compound compressor. The outer radii of the two rotors may differ. This construction may be modified and arranged as a two stage steam, air, or internal-combustion engine, or one chamber may be used as an engine cylinder and the other as a compressor.
