Abstract

1,175,763. Marine-propeller assemblies. T. G. SATTERTHWAITE AND J. B. MACY. 17 May, 1967 [7 July, 1966], No. 22834/67. Heading B7V. A marine-propeller assembly comprises a hub 19 that is rendered hollow and integral with a plurality of blades 21, a portion of said being cylindrical and supported by a bearing bush 13 lodged within a cylindrical opening 11 in the stern 10 of a ship. The end of the hub remoted from the blades is furnished with a flange that is coupled to shafting 36 by a plurality of bolts 41. The bush 13 is constituted by a plurality of axially-orientated rubber segments or staves 12, which are retained in the opening 11 by a ring 16 and a seal assembly 14. A slot (35), Fig. 3 (not shown), may be formed between two of the blades 21 to facilitate insertion of the staves 12 into the opening 11. In a second embodiment, Fig. 4, the blades 51 are removable from a hollow cylindrical hub 52 that is lodged in a bearing bush 53 and coupled to shafting 36 by studs 57, said bush being similar to the bush 13 aforesaid. A cap 59 is bolted to the rearward end of the hub to seal a central bore 58 that gives access to studs (63) or 77), Figs. 5 and 6 (not shown), which retain conic roots (62 or 72) on the radially innermost ends of the blades within recesses (61 or 73) of similar shape in the hub.
