G. MEIER PROPELLER BLADE Feb. 21, 1950 Filed June 4, i946 R M o a VM mw fi A .af
Patented Feb. 21, 1950 UNITED STATES PATENT OFFICE 2,498,170 7 PROPELLER BLADES Gustav Meier, West New Brighton, N. Y. Application June 4, 1946, Serial No. 674,267 2 Claims. (Cl. 170-170) This invention relates provements in propellers and it has for its specific of water from the center the tips of the propeller so-called slip.
Thus the main object of the present invention is to attain a reduction in said slip.
Another object of the invention is to increase the efliciency of the propeller blades.
A further object of the invention is to increase the speed of a ship.
A still further object of the invention is to increase the pulling power of the propeller.
A further object of the invention is to increase the pulling power of a ship.
An ancillary object of the present invention is to reduce the economical cost per shaft horsepower.
With the above and other objects in view, this invention consists of the novel features of construction, combination and arrangement of parts, hereinafter fully described, claimed and to new and useful imwith two or more blades, object to reduce the flow of the propeller towards blades to minimize the parts in all views, and in which:
Figure 1 is an elevation of a left hand propeller.
Figure 2 is an elevation of a right hand propeller.
Figure 3 is a top plan view of a propeller, as shown in Figure 1, looking down towards the propeller shaft.
Figure 4 is a top plan view of a propeller, as shown in Figure 2, looking down towards the propeller shaft.
Figure 5 is a section on the line 5-5 in Figure 1, showing the ribs cast in the propeller blade.
Figure 6 is also, a section in part, on the line 55 in Figure 1, but showing the ribs bolted to the propeller blade by countersunk screws, or the like.
mounted upon a shaft 19 the said blade has its entering edge as indicated at 12, and the blade is formed with one or more ribs I 3,
a certain distance from one another, and concentric with the bore of the propeller hub.
In Figure 2 is shown a right hand view of a )ropeller blade l0 adapted for 10w revolution, ind secured to a hub ll; said blade has its enering edge at 12' and is formed with eccentricaly arranged ribs I 3', which ribs, one or more, are tapered, as shown at 14 in Figure 4, comnencing and narrowing from the edge entering be water towards the edge leaving the water.
and described herein.
What I claim as new, and desire to secure by Letters Patent of the United States, is:
1. A propeller having a number of blades and a narrowing from the edge entering the water towards the edge leaving the water.
2. A propeller having rowing from the edge the edge leaving the water.
