ADJUSTABLE HEIGHT PROPELLER AND DRIVE ASSEMBLY Filed March 15, 1963 a z 7w itlll-lllllli INVENTOR. Tneoooznc B. Eowgzos A-rw-oeNey ing screw 42 prevents the elevating screw from being withdrawn completely from nut 43;
It should be obvious that other elevating means may be. substituted for elevating screw 4-2 to effect the raising and lowering of steering bar 26. For example a rack and pinion arrangement might be used with the rack afiixed to the steering bar and the elevating motor atlixed to worm gear 30 but placed off to one side from which point it could drive the rack member in an upward or downward direction by a pinion gear. The elevating screw arrangement illustrated is to be preferred, however, since it is the more compact and less subject to breakdown.
The mode of operation of the adjustable height propeller and drive assembly will be reviewed. The propeller is driven by the crafts engine through driving memher 6, upper bevel gears 12 and 13, driving sleeve 14, vertical drive shaft 17, lower bevel gears 22 and 23 and propeller shaft 24. For steering or reversing the craft, the propeller assembly 26 is caused to rotate about a vertical axis by the rotation of steering bar 26. Bar 26 is turned by steering tube 27 and worm gear 30 in response to the action of steering motor 38. Propeller assembly 20 is raised or lowered along a vertical axis by elevating motor which through the interaction of ele vating screw 4-2 and nut 43 causes steering bar 26 to slide up and down within steering tube 27. i
Many changes may be made in the mechanism illustrated without departing from the spirit of the invention. For example, the steering and elevating motors might be removed to remote locations. and suitable mechanical link- .13
age used to turn steering tube 27 and elevating screw 42; or the steering tube and elevating screw might be operated manually.
