UNITED STATES PETER MABCZYNSKI, or MILWAUKEE, WISCONSIN PROPELLER Application filed October 22, 1927. Serial No. 227,996. I
My invention refers to propellers, the same main blade, in the event of damage to the I i being equally adaptable to marine and air propulsion.- I v The object of my invention isjto increase 5 the efficiency of'the standard propeller, and
with this in view, provision'is made for increasing the area: of the propeller blades by v the application thereto of multiple auxiliary vanes.
With the above object in View the inven tion consists in certain peculiarities of construction and combination-of parts as are to be hereinafter set forth with reference to the accompanying drawing.
- The drawing illustrates a face view of the propeller,embodying the features of my in vention.
Referring by characters to thedrawing, 1
represents any type.v of standard hub having extended therefrom standard radial blades 2-2. It is understood that these blades may be varied to meet the requirements and in o f the county of Milwaukee, and State ofW1s- 7 accordance with well-known principles 0 standard propeller construction.
I. Secured tothe ends of the blades 2 in this exemplification ofmy invention, are pairs of auxiliary vanes 3-3, which vanes are spaced "from the main propeller blade in each instance, and" are rigidly secured thereto by I posts forming a triangular tying connection posts 4 and 5, it being preferable to provide 7 a single intermediate post and a pairof outer I to the main blade. 1
Obviously the auxiliary blades may be varied innumberto meet certain requirements,-
and the'shapes of said auxiliary vanes preferably coincide with the shape of the ends of the standard blade.- a
It isobvious from the foregoing descrip- 'ing or'pushingpower of the propeller, and
7 that said propeller so arranged can be rotated efficiency is maintained. '7 Furthermore, the
at a slower speed and at the same time greater auxiliary vanes, would still function.
-While I have shown and described one simple 'exemplification of my invention as a pair of auxiliary vanes associated with each of said main vanes and of the same size and shape and located adjacent the outer ends and on opposite sides of the main vanes, said auxiliary vanes being of oval shape with their larger ends outermost and rigidly secured to said main vanesby a pair of laterends and an inner post at their inner and smaller ends.
In testimony that I claim the foregoing I have hereuntosetmy hand at Milwaukee, in
consin.
ally spaced posts at their. outer and larger 7 tion that the great increase in area at the ends I i ofthe blades will materially increase the pull-
