Abstract

197,914. Soc. Rateau. May 17, 1922, [Convention date]. Pumping machines and fan apparatus.-In a turbine - driven blower having axial- How turbine blades and blower blades on the same wheel, diffusing devices are provided producing a movement of the exhausted motive and actuated fluids in the same direction. The arms f, Fig. 1, carry a stationary spindle g supporting on ball-bearings the hub i with the blades a of the helicoidal blower. The blades are surrounded by a rim b carrying two rings of turbine blades c, c<1> separated by the stationary guide blades d mounted in the outer casing. Other guide blades p and a diffuser are arranged on the outlet side of the driving wheel. The intake e of the turbine is carried by the arms f. The turbine driving fluid passes through the rings of blades and the diffuser l to mix with the fluid drawn through the diffuser k and diffuser j, or if desired the turbine, driving fluid may be exhausted through a separate branch m. The Specification, as open to inspection under Sect. 91 (3) (a) comprises also the modification shown in Fig. 3 (Cancelled), in which the blades n of a radial turbine are mounted on the cheek o of a centrifugal blower and both fluids move radially outwards. Guide blades p cause the turbine driving fluid to be injected into the fluid from the blower to increase the suction effect of the blower, or the turbine driving fluid may pass through a separate exhaust s. This subjectmatter does not appear in the Specification as accepted.
