Abstract

843,995. Axial-flow fans. HUDSON ENGINEERING CORPORATION. May 27,1958, No. 16859/58. Class 110 (1). The conical shank 13 (Fig. 1) of a fan blade 10 is mounted in a correspondingly tapered opening in a hub 11 and can be moved axially outwardly from an initial position, in which the blade is free to be turned to vary its pitch, to a fixed position, in tight non-rotative engagement with the opening, by a device 20 engaging a fixed shoulder 14 on the hub which applies an endwise force without substantial torque to the inner end of the blade shank. The opening is formed in a clamp secured to the hub and comprising members 15, 16, bolted together, and an aperture 21 is formed in the clamp to give access to the device 20 which comprises a head 24 and a part 23 having a threaded connection with the shank. In the case of a blade, e.g. of plastic material, having a shank hollowed by a recess 25 (Fig. 3), the part 23 engages a threaded opening in a metallic disc 28 abutting a resilient plug 26 fitting the recess, to provide an even distribution of pressure. The plate 28 bears directly against the end of the shank if the latter is solid, or the part 23 may engage a threaded bore in the shank, no plate then being required. The cylindrical shank (Fig. 6) of a conventional blade may be provided with a suitably tapered exterior by means of a bushing 33 retained thereon by a disc 32 secured to the shank. The device 20 may abut the end of the shank and have threaded engagement with the hub.
