ADJUSTABLE PROPELLER

Some interesting claims are made for ', a new adjustable propeller which has recently been- tested in a Swedish auxiliary' sailing vessel. The Kamewe propeller ,as it is called, .is based upon an invention for turbine machinery made by Professor Kaplan 25 "years ," ago, and is being manufactured by. Karlstads Mek. Verkstads. Sweden,says an overseas exchange. It has been fitted to the auxiliary vessel Bane, of Nordvik. The hydraulic method.. employed for the new propeller is said' to be extremely simple; all that~~~is needed is a small lever like that on an engine-room'telegraph, and the effect' is immediate. Lubrication is automatic, and the results attained with the Rane have fully come up to expectations. The propeller has also been found; to have excellent qualities when passing through ice. . It often happens that vessels have to change their propellers . in order to obtain' the most efficient result, but this is unnecessary when a ' Kamewe propeller is fitted, as the angle of the blades can easily be adjusted to the most effective position.v Furthe- .\ more;; it-is claimed,f the prpneller'caa|~ be usfed'to a niuCh greater"ej^te"nt;for;" manoeuvring purposes; 1 the machinery -~ can run at full speed while the speed*'. and direction ahead or astern of the vessel is being controlled by changing' the angle of the propeller blades.
